The circumference of a pizza is 75.36 in. What is the approximate area of the circle? Answers A.(113.04 in2)
B.(37.68 in2)
C.(1808.64 in2)
D.(452.16 in2)

Answers

Circumference = diameter x pi

Find the diameter:

75.36 = diameter x pi

Divide both sides by pi:

Diameter = 75.36/3.14 = 24 inches.

Area = pi x r^2

R = 1/2 diameter = 12

Area = 3.14 x 12^2

Area = 452.16 in^2

The answer is D.

Solve equation 2x-5=20-x

Answers

Answer:

x = 25/3

Step-by-step explanation:

2x-5=20-x

2x-5+5=x+20+5 (add 5 both to both sides)

2x = -x + 25

2x + x = -x + x + 25 (add x to both sides)

3x = 25

3x/3 = 25/3 (divide both sides by 3)

x = 25/3

Which of the numbers below are exactly divisible by 9 115 504 968 646 882

Answers

504 and 882 are both exactly divisible by 9, which means that the quotient will come out as a whole number with no decimals when the number is divided by, in this case, 9. 

Final answer:

Applying the rule that a number is divisible by 9 if the sum of its digits is divisible by 9, we find that 504 and 882 from the list (115, 504, 968, 646, 882) are divisible by 9.

Explanation:

To identify numbers that are divisible by 9, we can follow this rule: A number is divisible by 9 if the sum of its digits is divisible by 9. So, applying this rule to the numbers given (115, 504, 968, 646, 882), we find:

115: 1+1+5 = 7, which is not divisible by 9.

504: 5+0+4 = 9, which is divisible by 9. So 504 is divisible by 9.

968: 9+6+8 = 23, which is not divisible by 9.

646: 6+4+6 = 16, which is not divisible by 9.

882: 8+8+2 = 18, which is divisible by 9. So 882 is divisible by 9.

kirby often forgets to switch the inequity sign when dividing a negative. when solving 3x-10≥x, should kirby collect the variables on the left or the right? why?

Answers

You should collect the variable on the left side since you can't have two variables of the same letter on each side.so you would take the variable from the right side and subtract it from the left. So subtract x on both sides. Your new problem is 2x-10 is greater than or equal to 0. Now you add 10 on both sides. Your new problem is 2x is greater than or equal to 10. Now divide by 2 on both sides. Your answer would be x is greater than or equal to 5

Solve the equation by taking the square root 4(x+1)^2=100

Answers

Answer:

Step-by-step explanation:

4(x+1)²=100

(x+1)²= 5²

(x+1)²- 5² = 0

(x+1-5)(x+1+5) = 0  by identity : a² - b ² = (a - b) (a+b)

(x - 4 ) (x+6) =0

x - 4 = 0 or x+6 = 0

x = 4  or x = - 6
