Answer:
If Kevin can ride 13/2 kilometers in 3/5 of an hour then he can ride 13/6 in 1/5 of an hour. If you multiply 1/5 of an hour by 5 you would get an hour which would also be 5x the distance as 13/6. Kevin can bike 65/6 or 10 and 5/6 kilometers in an hour.
The measures of two consecutive angles of a parallelogram are in the ratio 6:3. What is the measure of an acute angle of the parallelogram?
A) 15° B) 30° C) 60° D) 90°
Help Plz I'm Almost Done
Answer: choice C) 60 degrees
smaller angle = 3*x; larger angle = 6*x
The two angles are supplementary, so they add to 180
6x+3x = 180
9x = 180
x = 180/9
x = 20
If x = 20, then,
smaller angle = 3*x = 3*20 = 60 degrees
(the other angle being 6*x = 6*20 = 120; note how 60+120 = 180)

Which value of x makes the inequality 2(8 – x) < 4 true?
A. x = –16
B. x = –9
C. x = 4
D. x = 10
First, let's ignore the answer choices and solve for a value of x ourselves.
2(8 - x) < 4
Distributive property.
16 - 2x < 4
Subtract 16 from both sides.
-2x < -12
Divide both sides by -2 (and flip the inequality sign)
x > 6
The value of x is going to be greater than 6, and so, we can observe the answer choices, and whichever value is greater than 6, is the correct answer.
In this case, there is only one answer, and that is D, x = 10.Answer:
d x=10

A furniture maker is building a bookshelf. He needs to cut rectangular pieces of wood to a length of 5/12 foot and a width of 2/3 foot.What is the area of a piece of wood that size?
Answer:
[tex]\frac{5}{18}[/tex] square feet.
Step-by-step explanation:
We have been given that the length of a rectangular piece of wood is 5/12 foot and width is 2/3 foot.
Since area of a rectangle is width times length, so to find the area of piece of wood we will multiply 5/12 by 2/3.
[tex]\text{Area of wood}=\frac{5}{12}\times \frac{2}{3}[/tex]
[tex]\text{Area of wood}=\frac{5}{6}\times \frac{1}{3}[/tex]
[tex]\text{Area of wood}=\frac{5}{6\times 3}[/tex]
[tex]\text{Area of wood}=\frac{5}{18}[/tex]
Therefore, area of piece of wood will be [tex]\frac{5}{18}[/tex] square feet.
A can has a radius of 2 inches and a volume of 62.8 cubic inches. Find the height of the can.
The formula for the volume of a cylinder is V=\pi r^2h V = π r 2 h . Rewrite this formula to solve for h.
Use your formula to find the height, h, of the can. Use 3.14 for \pi π .
By rearranging the formula for the volume of a cylinder to solve for height, and substituting the given values for volume and radius, we find that the height of the can is 5 inches.
To solve for the height h of the cylinder, we need to rearrange the formula for the volume of a cylinder, V =
2h, to solve for h. This is done by dividing both sides of the equation by
2, thus isolating h on one side of the equation.
The rearranged formula becomes:
h = V / (2)
Using the given volume of the can, 62.8 cubic inches, and the given radius of 2 inches, we plug these values into our formula:
h = 62.8 / (3.14 × 2²)
h = 62.8 / (3.14 × 4)
h = 62.8 / 12.56
h = 5 inches
Therefore, the height of the can is 5 inches.
You will always get the same result in a numerical expression no matter the order in which you perform the operations
Answer:
i just did the quiz and its FALSE i got it wrong so i thought you should have a right answer
Step-by-step explanation:
The order of operations in mathematics ensures that the result of a numerical expression is the same regardless of the order in which the operations are performed. - True
Explanation:In mathematics, the order of operations is a set of rules that dictate the order in which mathematical operations should be performed in an expression. Following these rules ensures that you always get the same result, regardless of the order in which the operations are performed.
The order of operations, also known as PEMDAS, stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). For example, in the expression 4 + 5 × 2, according to the order of operations, you would perform the multiplication first and then the addition. So, the correct way to evaluate this expression would be 4 + (5 × 2) = 4 + 10 = 14.

Given quadrilateral ABCD, if diagonals AC and BD bisect each other, and angle ABC=91°, but you know nothing about any lengths in the diagram, what special figure MUST ABCD be? A rhombus or a parallelogram? HOW DO YOU KNOW.
Answer:
ABCD must be a paralellogram
Step-by-step explanation:
In parallelogram, rectangle, square and rhombus the diagonals bisect each other. Since angle ABC=91°, then this quadrilateral cannot be rectangle and cannot be square, because rectangle and square have all right angles (90°).
If diagonals of a quadrilateral bisect each other, then quadrilateral is parallelogram. A rhombus is a parallelogram with all congruent sides.
You know nothing about any lengths in the diagram, then you can state that this quadrilateral is parallelogram (always) and can be rhombus (sometimes).

Answer:
[tex]3m^2+5n^2+8mn[/tex]
[tex]x^2-11x+17[/tex];0
Step-by-step explanation:
We have been given [tex]m^2+3mn−n^2 [/tex] and [tex]4m^2+5mn+6n^2[/tex]
for (1) we will subtract [tex]4m^2+5mn+6n^2[/tex] from [tex]m^2+3mn−n^2 [/tex] that is:
[tex]4m^2+5mn+6n^2-m^2+3mn-n^2[/tex]
Now, simplify the like terms we get:
[tex]4m^2-m^2+6n^2-n^2+5mn+3mn[/tex]
After simplification we get:
[tex]3m^2+5n^2+8mn[/tex]
Hence, [tex]3m^2+5n^2+8mn[/tex] is the required result.
(2) Now, we need to find how much less than [tex]3x^2-7x+9[/tex] is [tex]2x^2+4x-8[/tex]
Subtract [tex]3x^2-7x+9[/tex] from [tex]2x^2+4x-8[/tex] we get:
[tex]3x^2-7x+9-2x^2-4x+8[/tex]
After simplifying like terms
[tex]x^2-11x+17[/tex]
When x=2 the the above expression becomes:
[tex](2)^2-11(2)+17[/tex]
[tex]4-22+17=0[/tex]
For the first question, 4m^2+5mn+6n^2 is 3m^2+2mn+7n^2 greater than m^2+3mn-n^2. For the second question, 3x^2-7x+9 is x^2 -11x + 17 less than 2x^2+4x−8 and the value of the result when x=2 is 12.
Explanation:For the first question, begin by subtracting the given expressions (m^2 + 3mn - n^2) from (4m^2+5mn+6n^2). This equates to:
(4m^2 + 5mn + 6n^2) - (m^2 + 3mn - n^2) = 3m^2 + 2mn + 7n^2
For the second question, we subtract (2x^2+4x−8) from (3x^2−7x+9). This is equal to:
(3x^2−7x+9) - (2x^2+4x−8) = x^2 -11x + 17
To find the value of the result when x=2, simple plug in '2' wherever x is in the equation, giving the result 17 - 22 + 17 = 12

What is the largest number of identical goody bags that can be using 50 bouncy balls and 110 pokemon cards?
Answer:
10 goody bags.
Step-by-step explanation:
We are asked to find the largest number of identical goody bags that can be using 50 bouncy balls and 110 pokemon cards.
In order to solve our problem we will use GCF (Greatest common factor). Let us find out GCF of 50 and 110.
The factors of 50 are: 1, 2, 5, 10, 25, 50.
The factors of 110 are: 1, 2, 5, 10, 11, 22, 55, 110.
We can see that GCF of 50 and 110 is 10 as 10*11=110 and 10*5=50.
Therefore, the largest number of identical goody bags is 10 with 5 bouncy balls and 11 pokemon cards in each goody bag.

Seattle, wa and san francisco, ca lie on the same longitudinal line. san francisco is at 38° latitude and seattle is at 47° latitude. if the earth is a sphere of radius 4000 miles, use arc length to find the distance between the cities. [use π = 3.14, and round to the nearest mile.]
Step 1.
Calculate measure of angle α:
[tex]47^o-38^o=9^o[/tex]
Step 2.
Calculate what fraction of the angle 360° is the angle α:
[tex]\dfrac{9^o}{360^o}=\dfrac{1}{40}[/tex]
Step 3.
Calculate the circumference of the Earth (circle):
[tex]C=2\pi r\to C=2\pi\cdot4000=8000\pi\ mi[/tex]
Step 4.
The length of arc is equal 1/40 of the circumference:
[tex]\dfrac{1}{40}C=\dfrac{1}{40}\cdot8000\pi=200\pi\ mi[/tex]
[tex]\pi\approx3.14\to\dfrac{1}{40}C\approx200\cdot3.14=628\ mi[/tex]
The distance between San Francisco, CA, and Seattle, WA, along the longitudinal line is approximately 628 miles, calculated using the formula for arc length of a sphere, considering the Earth's radius and the difference in degrees of latitude.
Explanation:The question revolves around the concept of calculating the arc length in degrees, which is a topic in mathematics, specifically trigonometry.
The formula for calculating the arc length of a sphere is arc length = radius x angle (in radians).
We already know the radius of the earth (4000 miles) and the difference in latitude between Seattle and San Francisco (47°-38°=9°).
However, in the formula, we need the angle to be in radians. To convert degrees to radians, we use the formula 1 degree = π/180 radians.
So, 9° equals 9*(π/180) = 0.157 radians.
Now, we substitute the values into the formula: arc length = 4000 miles * 0.157 radians. This gives an answer of approximately 628 miles.
Therefore, the distance between San Francisco, CA, and Seattle, WA, along the longitudinal line is about 628 miles.

Answer:
40% of the pieces of fruit in the Bowl are apples.
Step-by-step explanation:
Given the statement:- There are 15 pieces of fruit in a bowl and six of them are apples.
⇒ Total number of pieces of fruit in a bowl = 15 pieces
and
Number of pieces of apple in a bowl = 6 pieces.
To find the percentage of the pieces of fruit in the Bowl are apples.
[tex]Percentage = \frac{Number of pieces of apple in bowl}{Total number of pieces of fruit in Bowl} \times 100[/tex]

A company makes and sells charm bracelets. The cost of producing x bracelets is represented by the function. C(x)=180+8x. The revenue earned for selling x bracelets is represented by the function R(x)=20x. Write and simplify a function P the represents the profit made from selling x bracelets. How many must the company sell to break even
Answer:
Minimum 15 bracelets to be sold to meet the break even.
Step-by-step explanation:
The cost price of bracelets is represented by C(x) =180+8x
The revenue earned (selling price) is represented by R(x) =20x
In these two functions x represents number of bracelets.
If P represents the profit then P = 20x-(180+8x)
P = 20x-180-8x = (12x-180)
For break even profit P = 0
12x-180 =0
12x = 180
x = 180÷12
x = 15
So minimum quantity of bracelets to be sold is 15 for the break even.

if a normal distribution has a mean of 132 and a standard deviation of 20 what is the value that has a z score of 1.8?
Answer:
168 = x
Step-by-step explanation:
mean = u=132
standard deviation =sigma = 20
z score =z=1.8
The formula is
z = (x-u)/ sigma
Substituting what we know
1.8 = (x-132)/20
Multiply by 20
1.8*20 = (x-132)/20 *20
36 = x-132
Add 132 to each side
36+132 = x-132+132
168 = x
Multiply the standard deviation by the z-score and add that to the mean:
Value = 132 + (20*1.8) = 132 + 36 = 168
The value would be 168.
