Find the area of the factor
Explain step by step for Braininess
Answer:
~78.54 mi^2
Step-by-step explanation:
The area of a circle is defined as π r^2. The radius is 10 miles. 10^2 is 100. 100 x π is roughly 314.16. Since we know the angle is 90 degrees, we know that it makes up one fourth of the entire area. 314.16 divided by 4 is 78.54.

Randy and his 4 friends take a trip to an amusement park. They eachi buy a pass for $15.00 plus a
souvenir tee shirt. If they spent a total of $115.00, how much did each tee shirt cost?
Answer:
55 all together or 13.75 per 1
Step-by-step explanation:
Answer: $13.75
Step-by-step explanation:
Let's take the given number first
four friends bought $15.00 passes for an amusement park
Now we need to multiply 15 by 3 to get that total
15x4=60
Now we need to take the total amount spent during the day and subtract it by 60
115-60=55
Now we need to divide 55 by 4 to get the total price of each shirt
55/4
$13.75
PLEASE HELP IM GIVING 100 POINTS AND BRAINLIEST IF THE ANSWERS RIGHT
A six-sided number cube labeled 1 through 6 is rolled 600 times. An odd number is rolled 272 times. Compare the experimental probability of rolling an odd number with the relative frequency of rolling an odd number and select one of the statements below that best describes the situation. (5 points)
a
The experimental probability and relative frequency are the same.
b
The experimental probability is larger than the relative frequency.
c
The experiment probability is smaller than the relative frequency.
d
There is not enough information to determine the relative frequency.
Answer:
Relative frequency is defined as the number of "desired" results divided by the total number of possible results. Experimental probability is defined the same way. This means that the first choice is best, the experimental probability and relative frequency are the same.
The theoretical probability, on the other hand, would be 0.5, or 300/600, which is larger than the experimental probability.

O y = {x+3
O y=x+2
O y=- Žx+3
O y=-{x+ 2
Answer:
The equation of the line is [tex]y = \frac{2x}{3} - 2[/tex]
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:
[tex]y = mx + b[/tex]
In which m is the slope and b is the y-intercept.
Parallel lines:
When two lines are parallel, they have the same slope.
Finding the slope:
When we have two points on a line, the slope is given by the change in y divided by the change in x.
In this question, we have these following points: (0,-1) and (3,1)
Change in y: 1 - (-1) = 1 + 1 = 2
Change in x: 3 - 0 = 3
Slope: [tex]m = \frac{2}{3}[/tex]
The equation of the line has the following format:
[tex]y = \frac{2x}{3} + b[/tex]
x-intercept of 3
This means that when [tex]y = 0, x = 3[/tex]. We use this to find b. So
[tex]y = \frac{2x}{3} + b[/tex]
[tex]0 = \frac{2*3}{3} + b[/tex]
[tex]0 = 2 + b[/tex]
[tex]b = -2[/tex]
So
[tex]y = \frac{2x}{3} - 2[/tex]

Answer:
45.18 mi
Step-by-step explanation:
What it is asking is to find the value of C.
Formula we're going to use:
[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
C is the hypotenuse.
Replace with given values, so
[tex] {19}^{2} + {41}^{2} = {c}^{2} [/tex]
Rewrite so there is no squared
[tex]361 + 1681 = {c}^{2} [/tex]
Add the numbers
[tex]2042 = {c}^{2} [/tex]
Find the value of C by square rooting 2042
[tex] \sqrt{2042} = 45.1884941108[/tex]

the diameter of circle A is 8 inches. the diameter of circle B is 4 inches greater then the diameter of circle A. The diameter of circle C is 4 inches greater then the diameter of circle B
the area of circle A is ____ the area of circle B is ____ the area of circle C
Answer:
Step-by-step explanation:
radius of A = 4 in
area of A = 16π in²
radius of B = 6 in
area of B = 36π in²
radius of C = 8 in
area of C = 64π in²
Area of A is 16π/(36π) the area of B = 4/9 the area of B
Area of B is 36π/(64π) the area of C = 9/16 the area of B
