Brendan ran a total of 8 miles over the course of 4 track practices.
How many track practices would it take for Brendan to run 10 miles? Solve using unit rates.
Answer:
5 track practices
Step-by-step explanation:
So if he ran 8 miles in 4 track practices, he ran 2 miles in each.
So it would take 5 track practices to do it.

The radius of the cone is 7 in and y = 25 in. What is the volume of the cone in terms of r?
х
O 392nt in
O 408rt in
0 112r in
O 117rt in
Answer:
Hi there!
The correct answer is: 408r in
Step-by-step explanation:
The formula for the volume of the cone is: V = [tex]\frac{1}{3}[/tex]π[tex]r^{2} h[/tex]
where h stands for height, in this case it's y=25
r stands for radius, in this case it's 7 in
when it says leave in terms of "r" it simply means don't multiply the π in
Answer:
392nt in

find the value of p in the equation 2p-1 over 5= p-1 over 3
Answer:
p = -2
Step-by-step explanation:
(2p -1)/5 = (p-1)/3
Using cross products
(2p-1) *3 = (p-1)*5
Distribute
6p-3 = 5p -5
Subtract 5p from each side
6p-5p -3 = 5p-5p -5
p -3 = -5
Add 3 to each side
p-3+3 = -5+3
p =-2

Area of trapezoid: a+b/ 2 * H
a = top, b= bottom, H = height
6+14/2 * 8
20/2 *8
10*8
80
Answer:
20
Step-by-step explanation:
To find area using coordinates, you would take the y-value of the first coordinate and the x-value of the second coordinate and multiply them. Then, take the x-value of the first coordinate and multiply it with the second y-coordinate. Take the second number and subtract it from the first number. for multiple coordinates, you would multiply the first and the second, the second and the third, and so on. Once you reach the last coordinate, just multiply it by the first again. then, take all of the numbers, from multiplying your coordinates and add them together and divide them by 2 to find your area.
We would start with coordinate (8,1) here because it's letter variable is W, which is first of the others alphabetically.
(8,1) (1,1)
1 x 1 = 1
8 x 1 = 8
1 - 8 = -7
next coordinate:
(1,1) (2,5)
1 x 2 = 2
1 x 5 = 5
2 - 5 = -3
next:
(2,5) (5,5)
5 x 5 = 25
2 x 5 = 10
25 - 10 = 15
next:
(5,5) (8,1)
5 x 5 = 40
5 x 1 = 5
40 - 5 = 35
-7 - 3 + 15 + 35 = 40
40/2 = 20

Write the standard equation of a circle with center (-9,-4) and radius 15.
(x + 9)2 + (y + 4)2 = 5
(x + 4)2 + (y + 9)2 = 5
(x - 4)2 + (y- 9)2 = 5
(x - 9)2 + (y - 4)2 = 5
Answer:
Equation of a circle:
radius = the sq. rt of (x - h)^2 + (y - k)^2
Plug in the values for the center of a circle and the radius:
15 = the sq. rt of (x + 9)^2 + (y + 4)^2
(x + 9)^2 + (y + 4)^2 = 225
The answer is A or the first one.

The graph of a line in the xy - plane passes through the point (8,6) and
crosses the y axis at the point(0, -18). What is the x-intercept of the
line?
Answer:
(6,0)
Step-by-step explanation:
First, let's find the line. We can do that by using the slope-intercept form of a line which is y = mx + b where m and b are the slope and y-intercept respectively. We know b = -18 and we can find m by doing (-18 - 6) / (0 - 8) = -24 / -8 = 3. Therefore, the equation of the line is y = 3x - 18. To find the x-intercept, we'll set y equal to 0. We get 0 = 3x - 18 → 3x = 18 → x = 6. Therefore, the x-intercept is (6,0). Hope this helps!

The human body has a normal temperature of 98.6°F. Doctors will get worried if a sick patient has a temperature that
varies from the normal by more than 3°F. Create an absolute value inequality and solve it to determine what body
temperatures would be considered unhealthy.
Answer: | t- 98.6 | ≤ 3
Temperatures less than 95.6 and higher than 101.6 will be considered unhealthy.
Step-by-step explanation:
Hi, to answer this question we have to write an inequality
.
| t- 98.6 | ≤ 3
Where t is the body temperature.
The absolute value inequality has 2 solutions:
1st solution
t-98.6≤ 3
t ≤ 3+98.6
t≤ 101.6
2nd solution
-(t-98.6) ≤ 3
-t+98.6 ≤ 3
98.6-3 ≤ t
95.6≤ t
Both:
95.6≤ t ≤ 101.6
Temperatures less than 95.6 and higher than 101.6 will be considered unhealthy.

Find the distance between the points A and D.
Answer:
So we can first use the distance formula which is for 2 dimensional but seen as we're in 1 dimensions we dont have to use it. So we can just get the distance between them using a formula I made -
|a-d| = distance
So if we use that formula we can get that -7-(-2) = -7+2 = -5. Then take the absolute value which is 5.

In the picture above, parallel lines p and q are cut by transversal line t. If the measure of angle 1 is 11x+7 and the measure of angle 8 is x+17, then x is equal to and the measure of angle 1 is degrees. The measure of angle 8 is degrees. *please hurry*
Answer:
x = 13
Angle 1 = 150 degrees
Angle 8 = 30 degrees
Step-by-step explanation:
11x + 7 + x + 17 = 180
12x + 24 = 180
12x = 180 - 24
12x = 156
x = 13
11(13) + 7 = 150
(13) + 17 = 30
The co-interior angles are solved and x = 13
The measure of angle 1 = 150°
The measure of angle 1 = 30°
Given data:
Angles in parallel lines are angles that are created when two parallel lines are intersected by another line.
Alternate angles are equal
Corresponding angles are equal
Co-interior angles add up to 180°
The angles 1 and 8 are co-interior angles.
So, 11x + 7 + x + 17 = 180
12x + 24 = 180
12x = 180 - 24
12x = 156
x = 13
So, the measure of angle 1 = 11(13) + 7 = 150°
The measure of angle 8 = (13) + 17 = 30°
Hence , the parallel lines are solved.
