Answer: 6 teaspoons of sugar
Step-by-step explanation: Create a proportion
4 ounces of frosting = 2 teaspoons of sugar
8 ounces of frosting = 4 teaspoons of sugar
12 ounces of frosting = 6 teaspoons of sugar
To make 12 ounces of frosting, you would need 6 teaspoons of sugar.
Explanation:To find out how much sugar is needed to make 12 ounces of frosting, we can set up a proportion using the given information. The recipe calls for 2 teaspoons of sugar for 4 ounces of frosting. We can set up the proportion: 2 teaspoons / 4 ounces = x teaspoons / 12 ounces.
To solve the proportion, we can cross multiply and divide. So, (2 teaspoons)(12 ounces) = (4 ounces)(x teaspoons). This simplifies to 24 = 4x. Dividing both sides by 4, we find that x = 6 teaspoons.
Therefore, you would need 6 teaspoons of sugar to make 12 ounces of frosting.

A tangent to a circle at point A is given, and point A is an endpoint of a chord, which is the same length as radius of the circle. What is the measure of angle between the tangent and the chord?
PLS HELP SQDANCEFAN!!!!! I NEED HELP I DON'T GET IT :((((
Answer:
30°
Step-by-step explanation:
Call the other end of the chord point B and the center of the circle point O. Then triangle AOB is an equilateral triangle, since OA = OB = AB.
Angle OAB is the internal angle of that triangle, so is 60°. Since OA is perpendicular to the tangent line (makes an angle of 90°), The angle between the tangent line and the chord must be ...
90° - 60° = 30°
___
The other way you know this is that central angle AOB is 60°, and the tangent-to-chord angle is half that, or 30°.
_____
One way to remember the angle relationship between a tangent line and a chord is this:
Consider a point C on long arc AB. The measure of inscribed angle ACB is half the measure of central angle AOB, no matter where C is on the circle. (If C happens to be on the short arc AB, then central angle AOB is a reflex angle, but the relationship still holds.) Consider what happens when C approaches A. The angle at vertex C is still the same: 1/2 the measure of central angle AOB. This remains true even in the limit when points A and C become coincident and line AC is a tangent at point A.
In what quadrant of the coordinate plane is the graph of the direct proportion located which is parallel to the graph, expressed by the formula:
Note: Please answer both questions in the same format (The direct proportion is ____. The graph is located on quadrants ___ and ___.).
Answer:
Part 1) The direct proportion is [tex]y=0.8x[/tex]. The graph is located on quadrants I and III
Part 2) The direct proportion is [tex]y=-0.4x[/tex]. The graph is located on quadrants II and IV
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]y=kx[/tex]
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
Part 1) we have
[tex]y=0.8x-1.6[/tex]
Remember that
If two lines are parallel, then their slopes are the same
In this problem, the slope of the given line is [tex]m=0.8[/tex]
therefore
The direct proportion is [tex]y=0.8x[/tex]
The graph is located on quadrants I and III
see the attached figure to better understand the problem
Part 2) we have
[tex]y=-0.4+1[/tex]
Remember that
If two lines are parallel, then their slopes are the same
In this problem, the slope of the given line is [tex]m=-0.4[/tex]
therefore
The direct proportion is [tex]y=-0.4x[/tex]
The graph is located on quadrants II and IV

Answer:
left 3 units and up 6 units
Step-by-step explanation:
we know that
The rule of the translation is equal to
[tex](x,y)------> (x-3,y+6)[/tex]
That means
(x-3)-----> The figure is moved 3 units to the left, because the number is negative
(y+6)----> The figure is moved 6 units up because the number is positive
Answer:

Step-by-step explanation:
In a city school, 60% of students have blue eyes, 55% have dark hair, and 35% have blue eyes and dark hair. What is the probability (rounded to the nearest whole percent) that a randomly selected student will have dark hair, given that the student has blue eyes?
Hint:
P(A|B)=P(A∩B) / P(B)
64%
58%
80%
20%
Answer:
58%
Step-by-step explanation:
This is a problem of conditional probability.
Let A represent the event that student has dark hair.
So P(A) = 55% = 0.55
Let B represents the event that student has blue eyes.
So, P(B) = 60% = 0.60
Probability that student has blue eyes and dark hairs = P(A and B) = 35% = 0.35
We are to find the probability that a randomly selected student will have dark hair, given that the student has blue eyes. Using the given formula and values, we get:
[tex]P(A|B)=\frac{P(A \cap B)}{P(B)}\\\\ P(A|B)=\frac{0.35}{0.60}\\\\ P(A|B)=0.58[/tex]
Therefore, there is 0.58 or 58% probability that the student will have dark hairs, given that the student has blue eyes.
The figures below are similar. Compare the smaller figure to the larger. Which of the following is the ratio of the perimeters of the figures?
Answer: first option
Step-by-step explanation:
As you can see in the figures shown in the image attached, the lenght of a side of the smaller figure is 2 inches and the the lenght of a side of the larger figure is 4 inches.
Therefore, you can find the ratio as following:
[tex]ratio=\frac{2in}{4in}[/tex]
Now, you must reduce the fraction. Therefore, you obtained that the ratio of the perimeters of the figures is:
[tex]ratio=\frac{1}{2}[/tex]
Which can be written in the following form:
[tex]ratio=1:2[/tex]
Then, the answer is the first option.
Lori bought gifts for her 3 borthers and 6 cousins. She bought 4 toy cars for each
Answer: 36 toy cars
Step-by-step explanation: If Lori bought gifts for her 3 brothers and 6 cousins then she bought gifts for 9 people (3+6). Since she bought 4 toy cars for each of them she bought 36, which is calculated by multiplying 9 x 4.
9 x 4 = 36
Lori bought a total of 36 gifts for her three brothers and six cousins since she bought four gifts for each of them. This was calculated by multiplying the total number of recipients (3+6) by the number of grants each person got (4).
Explanation:The question is asking how many gifts Lori bought in total. Since Lori bought four toy cars for each of her three brothers and six cousins, we need to multiply the total number of recipients by the number of gifts per person. This gives us (3 brothers + 6 cousins) * 4 skills = 36. So, Lori bought a total of 36 grants.

similarities between finding the perimeter and area of a polygon with and without the coordinate plane
A Polygon is shape with straight sides and must be closed. Polygon sides never touch and are classified according to the number of its sides. So:
A Triangle is any polygon with exactly 3 sidesA Quadrilateral is any polygon with exactly 4 sides. A Pentagon is any polygon with exactly 5 sides. An Hexagon is any polygon with exactly 6 sides. A Heptagon is any polygon with exactly 7 sides. An Octagon is any polygon with exactly 8 sides. A Nonagon is any polygon with exactly 9 sides. Decagon is any polygon with exactly 10 sides.1. WITH THE COORDINATE PLANE:If you have the coordinate plane, there are several ways to calculate the perimeter and area. If the polygon meaning that every side must have the same length and every angle must have the same measure, you just need the coordinates of two points and by using the distance formula you can calculate the length of that side. Then you must multiply the number of sides by that distance and this is the perimeter, but if the polygon is irregular you must calculate the length of each side of the polygon using the distance formula and then make the sum. To compute the area, you must divide the entire polygon in triangles, rectangles, parallelograms, etc, and then calculating the area of each figure using the formulas known for each type of figure.
2. WITHOUT THE COORDINATE PLANE:If you don't have the coordinate plane, you need to have the length of each side to calculate the perimeter or each side should be calculated by using trigonometry and other mathematical skills. If the polygon is regular or is a known figure (trapezoid, parallelogram, triangle) you can use the formulas you know to compute the area of that figure. On the other hand, if the polygon is irregular you should divide the polygon in other simple figures and calculate each area and then making the sum.
_______________________
In conclusion, for both ways you need to have the length of each side to find the perimeter and can use well known formulas to find the area of the figure.

Given sin0=6/11 and sec 0<0 find cos0 and tan0 (picture provided)
Answer:
[tex]cos(0\°)=-\frac{\sqrt{85}}{11}[/tex]
[tex]tan(0\°) = -\frac{6}{\sqrt{85}}\\\\[/tex]
Step-by-step explanation:
We know by definition that:
[tex]cos ^ 2(x) = 1-sin ^2(x)[/tex]
We also know that:
[tex]tan(x) = \frac{sin(x)}{cos(x)}[/tex]
[tex]sec(x) = \frac{1}{cos(x)}[/tex]
Then we can use these identities to solve the problem
if [tex]sin(0\°) = \frac{6}{11}[/tex] then [tex]cos^2(0\°) = 1-(\frac{6}{11})^2[/tex]
[tex]cos(0\°) = \±\sqrt{\frac{85}{121}}\\\\cos(0\°)=\±\frac{\sqrt{85}}{11}[/tex]
As [tex]sec(x) <0[/tex] then [tex]cos(x) <0[/tex]. Therefore we take the negative root:
[tex]cos(0\°)=-\frac{\sqrt{85}}{11}[/tex]
Now that we know [tex]sin(0\°)[/tex] and [tex]cos(0\°)[/tex] we can find [tex]tan(0\°)[/tex]
[tex]tan(0\°) = \frac{sin(0\°)}{cos(0\°)}\\\\tan(0\°) = \frac{\frac{6}{11}}{\frac{-\sqrt{85}}{11} }\\\\tan(0\°) = -\frac{6}{\sqrt{85}}\\\\[/tex]

Looking at the figure, the rectangle has the vertexes (2,1), (3,-3), (-5,-5) and (-6,-1). The parallelogram has the vertexes (2,7), (3,3), (3,-3), and (2,1).
The area of a parallelogram is base times height. We have 2 vertical lines at x=2 and x=3, so the height is 1. And the length of the line from (3,3) to (3,-3) is 6, so the base is 6. Therefore the area of the parallelogram is 1*6 = 6.
The rectangle is a tad trickier since it's not aligned with either the x or y axis. But we can use the Pythagorean theorem to get the lengths.
L = sqrt((2 - -6)^2 + (1 - -1)^2)
L = sqrt(8^2 + 2^2)
L = sqrt(64 + 4)
L = sqrt(68) = 2*sqrt(17)
W = sqrt((2-3)^2 + (1- -3)^2)
W = sqrt((-1)^2 + 4^2)
W = sqrt(1 + 16)
W = sqrt(17)
And the area is length * width, so:
2*sqrt(17)*sqrt(17) = 2 * 17 = 34
And the total area is the sum of the areas, so
34 + 6 = 40
So the area of the figure is 40 square units.
Answer:
40 units ^2
Step-by-step explanation:
when finding an odd shaped figure, make sure to divide it up into porportions. Then figure out the square and then the triangles.
the answer would be: 40 units ^2

B. None of these plants is yet producing actual widgets.
C. Plant A is the closest to producing actual widgets.
Answer:
B. None of these plants is yet producing actual widgets.
Step-by-step explanation:
As we can see in the graph, the number of days is on the x axis, and the number of widgets at y axis.
At 10 days, no line is above the '0' means no one is producing widgets at 10 days point.
Since the y axis represents number of widgets produced, this means none of the plants have produced more than 0 widgets yet.

a.) 0.0825 years of age per year
b.) 0.825 years of age per year
c.) 1.21 years of age per year
d.) -1.21 years of age per year
Answer:
a.) 0.0825 years of age per year
Step-by-step explanation:
By the given table,
The median age at the time of first marriage on 1950 = 22.8 years,
While, the median age on 1990 = 26.1 years,
Hence, the average rate of change in median age per year from 1950 to 1990
[tex]=\frac{22.8 - 26.1}{1950 - 1990}[/tex]
[tex]=\frac{-3.3}{-40}[/tex]

tabitha defines a sphere as the set of all points equidistant from a single point. Is Tabitha's definition valid?
answer; it is valid because all spheres fit this definition, and figures that are not spheres do not fit this definition.
definition is valid since center is exactly 1radius away from any point on the outersurface.
other figures do not fit this defn
Answer:
Tabitha's defintion is valid.Step-by-step explanation:
Her definition is valid because the sphere is basically defined by its radius, which is the equidistant points towards a center. If points are not equidistant, then that's not a sphere.
Also, Tabitha is considering "a set of points" referring to infinite points on the surface of the sphere. The single point she mentioned is the center.
Therefore, Tabitha's definition is valid because she's considering all elements that define a sphere.

A certain drug is made from only two ingredients: compound A and compound B. There are 3 milliliters of compound A used for every 4 milliliters of compound B. If a chemist wants to make 533 milliliters of the drug, how many milliliters of compound B are needed?
Answer:
[tex]304\dfrac{4}{7}\ milliliters[/tex]
Step-by-step explanation:
If there are 3 milliliters of compound A used for every 4 milliliters of compound B, then we can denote that we use 3x milliliters of compound A and 4x milliliters of compound B to get 533 milliliters of the drug. Thus,
[tex]3x+4x=533,\\ \\7x=533,\\ \\x=\dfrac{533}{7}\ milliliters.[/tex]
Hence, a chemist must take
[tex]4\cdot \dfrac{533}{7}=\dfrac{2132}{7}=304\dfrac{4}{7}\ milliliters[/tex]
of compound B.
Answer:
228.43 ml
Step-by-step explanation:
The ratio of compound A to compound B will be; 4: 3
4:3 is the same as 4x:3x where 4x is compound A and 3x is compound B.
We can solve for "x":
If amount of compound A is 4x and compound B is 3x;
Then; 4x + 3x = 533
7 x = 533
x = 533/7
Then amount of compound B is 3x = 3(533/7)
= 228.43 ml
Me banks left work at 5:15cpm it took him 1 1/4 hours to drive home at what time did me banks arrive home

the answer would be 6:30 pm
Step-by-step explanation:
if you left work at 5:15 and it took 1 1/4 min to get home
you would
find 1/4 witch would be 15 min because 60/4= 15
then add 1:15 to 5:15
1:15 + 5:15 = 6:30 pm
you arrived home at 6:30 pm
Mr. Banks would get home at 6:30 PM after leaving work at 5:15 PM and driving for 1 hour and 15 minutes.
The student asked what time Mr. Banks would arrive home if he left work at 5:15 PM and took 1 and 1/4 hours to drive home. To solve this, we need to add the travel time to the departure time. Since 1 and 1/4 hours is the same as 1 hour and 15 minutes, we simply add this to 5:15 PM. Adding 1 hour to 5:15 PM, we get 6:15 PM. Then, adding the remaining 15 minutes, we get 6:30 PM. This means Mr. Banks would arrive home around 6:30 PM.

A line has a slope of -3 and y-intercept of 5. write the equation of the line in slope intercept. form and explain how you would use the slope and y-intercept to graph the equation.
Equation: y= mx + b
y = -3x +5
Graph the y intercept first.
Go down three times on the y axis.
Go across one because of -3/1 .
The equation of the line is y = -3x + 5. To graph the equation, plot the y-intercept and use the slope to find additional points on the line.
Explanation:
The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. In this case, the slope is -3 and the y-intercept is 5, so the equation of the line is y = -3x + 5. To graph the equation, start by plotting the y-intercept of (0, 5). Then use the slope to find additional points on the line. For every increase of 1 on the x-axis, the y-value decreases by 3. You can use this pattern to plot more points and draw a straight line connecting them.

Step-by-step explanation:
Fixed Cost Per Deck = Total Fixed Cost/Estimated Deck Sales
Fixed Cost Per Deck = 85000/13000
Fixed Cost Per Deck = $7.08
Break Even Point in Units = Fixed Costs/ Sales Price per Unit - Variable Cost
Break Even Point in Units = 85000/11.95 - 3
Break Even Point in Units = 9497
Fixed Cost Per Deck = Total Fixed Cost/Estimated Deck Sales
Fixed Cost Per Deck = 85000/10000
Fixed Cost Per Deck = $8.50
Break Even Point in Units = Fixed Costs/ Sales Price per Unit - Variable Cost
Break Even Point in Units = 85000/12.95 - 3
Break Even Point in Units = 8543
Break Even Point in Units = Fixed Costs/ Sales Price per Unit - Variable Cost
Break Even Point in Units = 85000/13.45 - 3
Break Even Point in Units = 8134
1.Total Cost = Variable Cost/unit x Units Produced + Fixed cost
Total Cost = (3 x 13000) + 85000
Total Cost = 39000 + 85000
Total Cost = $124000
2.Total Cost = Variable Cost/unit x Units Produced + Fixed cost
Total Cost = (3 x 10000) + 85000
Total Cost = 30000 + 85000
Total Cost = $115000
3. $12.95 and $13.45.
Because the total cost is greater than the revenue.
Let's try at $12.95:
Revenue = 12.95 x 8000
Revenue = $103600
Total Cost = (3 x 8000) + 85000
Total Cost = 24000 + 85000
Total Cost = $109000
Profit = Revenue - Total Cost
Profit = 103600 - 109000
Profit = $-5400
Now at $13.45:
Revenue = 13.45 x 7000
Revenue = $94150
Total Cost = (3 x 7000) + 85000
Total Cost = 21000 + 85000
Total Cost = $106000
Profit = Revenue - Total Cost
Profit = 94150 - 106000
Profit = $-11850
4. The fixed costs to produce $13.45 decks is so much greater than the fixed costs to produce 10.95 due to the estimated deck sales.
