What is the measure of Angle 1 and 2? Enter your answer as a number.
Answers
The measure of angles can be in degrees, minutes of arc, and seconds of arc, with the example given (9:00 a.m. clock hands) resulting in a 90-degree angle.
Explanation:The measure of angles is often given in degrees, minutes of arc, and seconds of arc.
These units subdivide a degree into finer measurements, where one degree equals 60 minutes and one minute equals 60 seconds.
One example of using these measurements is in Astronomy, where astronomers measure the angular separation of stars in the sky.
Angles are crucial to understanding the positions and movements of celestial bodies.
Returning to the practice problem provided: 'What is the angle in degrees between the hour hand and the minute hand of a clock showing 9:00 a.m.?', we can calculate this using the understanding that each hour on the clock represents 30 degrees (360 degrees / 12 hours).
At 9:00 a.m., the hour hand is on the 9 and the minute hand is on the 12, creating a 90-degree angle between them.
Question 11(Multiple Choice Worth 5 points) Perform the requested operation or operations. f(x) = 4x + 6, g(x) = 5x2 Find (f + g)(x).
Answers
Answer:
(f + g)(x) = 5x^2 + 4x + 6
Step-by-step explanation:
The given functions are f(x) = 4x + 6 and g(x) = 5x^2
(f + g)(x) = f(x) + g(x)
= 4x + 6 + 5x^2
= 5x^2 + 4x + 6

a sample of 144 was taken from a population with a standard deviation of 36 inches. In this case the sample mean will be within how many inches of the population mean 99.7% of thew time?
Answers
Answer:
9 inches
Step-by-step explanation:
The population is within 6 standard deviations of the mean with a confidence of 99.7 percent, 3 above and 3 below
The standard deviation of the sample mean is equal to the population standard deviation divided by the square root of the sample size
population standard deviation = 36
sample size = 144
standard deviation of the sample mean = 36/ sqrt(144)
=36/12
=3
The margin of error is the number of standard deviations above the mean * the standard deviations
margin of error = 3 * 3
= 9 inches

What is the value of Y who knows please help me
Answers
Answer:
y =65
Step-by-step explanation:
We will call the unknown angle in the triangle x
Angle x plus 130 form a straight line
x+130 = 180
Subtract 130 from each side
x+130-130 = 180-130
x = 50
The three angles in the triangle add together to make 180 degrees
x+y+y = 180
We know angle x = 50
50 + 2y = 180
Subtract 50 from each side
50+2y-50 = 180-50
2y = 130
Divide each side by 2
2y/2 = 130/2
y = 65

FInd the slope of a line
Answers
Answer:
First I'm not exactly sure what you're asking but the equation for slope is:
Y2-Y1/X2-X1=M
Step-by-step explanation:
M is your slope
X1 and Y1 represent your first point
X2 and Y2 represent your second point
To translate you are finding the rate of change (slope) between two points
Answer: Slope = ∆y/∆x = y2-y1/x2-x1
Step-by-step explanation:
The slope of a line which is also known as the gradient can be gotten by taking the ratio of the change in coordinate of y-axis to the x-axis of the line.
Change in y axis = y2-y1
Where y2 and y1 are final length and initial length respectively on the y axis
Change in x axis = x2-x1
Where x2 and x1 are final length and initial length respectively on the x axis.
The slope of the line therefore gives;
Slope = ∆y/∆x = y2-y1/x2-x1

Step-by-step explanation:
This question asks us to find the difference in output or y values or consecutive x-values (values 1 unit away from each other). This is just a rate of change or slope. We will use the slope formula:
Slope:[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
We substitute [tex]x_1=-3\\y_1=-57.6[/tex] and [tex]x_2=-2\\y_2=-36.4[/tex]
[tex]m=\frac{-36.4-(-57.6)}{-2-(-3)}[/tex]
[tex]m=\frac{-36.4+57.6}{-2+3}=\frac{21.2}{1} =21.2[/tex]

Xavier downloaded 40 songs last week, including 14 jazz songs. What percent of Xavier's downloads were jazz songs
Answers
About 35% of the songs Xavier downloaded were jazz songs. This was calculated by dividing the number of jazz songs (14) by the total number of songs (40) and then multiplying the result by 100.
Explanation:Xavier downloaded a total of 40 songs. Out of these, 14 were jazz songs. To find the percentage of jazz songs out of the total, we need to divide the number of jazz songs by the total number of songs and then multiply the result by 100.
So, the calculation would be (14/40) * 100. When we do the math, we find that about 35% of Xavier's downloads were jazz songs.

triangle a'b'c' is a dilation of triangle abc. which is the correct description of the dilation?
Answers
Answer: A
Step-by-step explanation:
[tex]\overline{AB}[/tex] has a length of 6
[tex]\overline{A'B'}[/tex] has a length of 6 + 12 = 18, which is 3 times the length of [tex]\overline{AB}[/tex]
B = B' so this will be the center point
⇒ center B and a scale factor of 3
Answer:
Option A is the answer.
Step-by-step explanation:
Triangle A'B'C' is a dilation of triangle ABC.
We can apply the formula to get the scale factor as
Scale factor = [tex]\frac{\text{One side of triangle A'B'C'}}{\text{Corresponding side of triangle ABC}}[/tex]
= [tex]\frac{A'B'}{AB}[/tex]
= [tex]\frac{AB'+AA'}{AB}[/tex]
= [tex]\frac{6+12}{6}[/tex]
= [tex]\frac{18}{6}[/tex]
= 3
Therefore, ΔABC has been dilated with a scale factor of 3 about the point B as the center.
Option A is the answer.

Answers
$9.0.
Each person will owe $9.0.
STEP-BY-STEP SOLUTION:
Total amount of people:
= 3
Total bill:
= $31.84
Discount off total bill:
= 15%
Total bill after discount:
= 31.84 × ( 100% - 15% )
= 31.84 × 85%
= 27.064
Total bill after discount split evenly / Amount each person will owe:
= 27.064 ÷ 3
= 9.0213 ( 3 repeater )
= $9.0 ( rounded to the nearest tenth )
What are the coordinates of the midpoint of the segment whose endpoints are A (-1, -2) and B (6, 12)
x-coordinate:
y-coordinate:
Answers
Answer:
Mid point = [tex](\frac{5}{2} ,5)[/tex]
Step-by-step explanation:
We are given the coordinates of the end points of a line segment AB and we are to find the coordinates of its mid point.
The coordinates of the end points are: A (-1, -2) and B (6, 12).
We know the formula of the mid point:
Mid point = [tex](\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )[/tex]
So putting in the given values to find the mid point of line segment AB:
Mid point = [tex](\frac{-1+6}{2} ,\frac{-2+12}{2} )[/tex] = [tex](\frac{5}{2} ,5)[/tex]

Elaine has a $350 gift card to Target. Elaine spent $334.50 on a sound bar at Target. If the sales tax is 8%, what was her final bill? Does she have enough money on the gift card to pay for the sound bar?
