Broderick needs to solve the formula below for r. Which correctly describes the first step he should take?
The first step to solve for r is (J) He should divide both sides of the equation by π.
How to solve the formula for r?The equation is given as:
A= πr^2
Divide both sides of the equation by π.
So, we have:
r^2 = A/π
Hence, the first step to solve for r is (J) He should divide both sides of the equation by π.

The diameter of a circle is 8 feet. What is the angle measure of an arc a feet long?
Give the exact answer in simplest form.
20 points
Answer:
Given: circle
diameter = 10 cm => radius (R) = 5 cm
Find: measure of angle bounding sector = 11 π sq. cm.
Plan: determine what part of the circle’s total area equals the sector’s area.
Total Area of Circle A = π R^2 = π 5^2 = 25 π sq. cm.
Therefore: Sector Area = 11 π cm^2/25 π cm^2 = 11/25
Since the sector is 11/25 th of the circles area, the sector angle will measure 11/25 th of the circle’s circumference. They are proportional.
C = 2 π R = 2 π (5) = 10 π cm
Sector Arc = measure of sector angle = 11/25 (10 π) =
22π/5 radians
Answer: Sector Arc = 22π/5 Radians

Answer:
a.) 13 students
b.) 53 members
Step-by-step explanation:
a.) In the given equation of y=4x+13, "x" represents how many years have gone by since the club had started. The number "13" in this equation represents the y-intercept, or the value of "y" when x = 0. Therefore, when "x" is 0 years, there were 13 students in the clubs, meaning that the original group that started the club contained 13 students.
b.) Since the question asks how many members that the club will have after their tenth year and you already know that "x" in the equation y=4x+13 represents the number of years since the club started, all you have to do is plug 10 in for "x" in the equation; so, the equation will now look like this: y=4(10)+13. Keeping PEMDAS in mind, you first multiply 4 and 10 to get 40, and then you add 13 to get an answer of 53 members after year 10.
in a given classroom the number of girls is 10 greater than number of boys if the ratio of the number of girls to the number of boys is 7:5 then find a) the number of girls b) the number of boys c) the total number of students
Answer:
a) 35, b) 25, c) 60
Step-by-step explanation:
The number of girls is 10 more than the number of boys, so it's a good thing to choose a variable to represent the number of boys.
Number of boys: b
Number of girls: b + 10
Ratio of girls:boys is 7:5, so
[tex]\frac{b+10}{b}=\frac{7}{5}[/tex]
"Cross multiply" to get
[tex]7b=5(b+10)\\7b=5b+50\\2b=50\\b=25[/tex]
There are 25 boys. There are 10 more girls, so the number of girls is 35, and the total number of students is 60.
That's a packed classroom!

What is a line plot graph?A Line plot can be defined as a graph that displays data as points or check marks above a number line, showing the frequency of each value.
Given that, Mr. Petersen counted the number of coins collected by the students in his coin club and prepared the line plot.
We need to find how many students collected more than 1 coin,
Here each X represents a student,
The numbers of mark X above 2 and 3 = 4 and 8
Therefore, total students = 12
Hence, the number of students who collect more than one coin is 12.

if the radius of the circle is 8 units find the area of the hexagon
The sum of interior angle of the given regular hexagon is 720 degree. The area of the hexagon with side of 8 units is 96√3 square units
Area of a hexagonThe sum of interior angle of the given regular hexagon is 720 degrees
The measure of one of the angles is 120 degrees
<ABO = 120/2 = 60 degrees
Since all the angles of triangle ABO are the same, hence AB = 8 units
Determine the area of the hexagon
A = 3√3/2 a²
Substitute a = 8 units
A = 3√3/2 (8)²
A = 3√3/2 * 64
A = 3√3 * 32
A = 96√3 square units
Hence the area of the hexagon with side of 8 units is 96√3 square units

Solution:
Let h be the height of the triangle ABC.
Area of a triangle is:

Solve for x and y. You do not need to show your work
Answer:
[tex] \displaystyle x = \frac{21y + 2}{15} [/tex]
[tex] \displaystyle y = \frac{15x - 2}{21} [/tex]
Step-by-step explanation:
Solve for x:remove parentheses:
[tex] \displaystyle x + 7y = 6x - \frac{2}{3} [/tex]
move x to left hand side and y to right hand side and change its sign:
[tex] \displaystyle x - 6x = -7y - \frac{2}{3} [/tex]
simplify Substraction:
[tex] \displaystyle - 5x = \frac{-21y - 2}{3} [/tex]
divide both sides by -5:
[tex] \displaystyle x = \frac{21y + 2}{15} [/tex]
Solve for y:move x to the right hand side and change its sign:
[tex] \displaystyle 7y = 6x - x- \frac{2}{3} [/tex]
simplify Substraction:
[tex] \displaystyle 7y =5x- \frac{2}{3} [/tex]
simplify substraction:
[tex] \displaystyle 7y = \frac{15x - 2}{3} [/tex]
divide both sides by 7:
[tex] \displaystyle y = \frac{15x - 2}{21} [/tex]
