11. A program on television ran 30 minutes. The program ran seven minutes longer than three times the length of the commercials. Which equation represents this problem? (Points : 1)
3x + 7 = 30
x + 7 = 3(30)
3x = 30 + 7

Answer 1

10 is never cant have division by 0

Answer 2

number 9 is x*x=x to the power of two

Answer 3

9 true. always.

Answer 4

3x+7 =30

Answer 5

Yup

Answer 6

13. The Sears Tower is 1,454 feet tall. Let the height of the antenna on the tower be represented by the variable a. The total height of the building plus the antenna is 1,707 feet. Which equation represents this problem? (Points : 1)
1,454 = 1,707 + a
1,454+a=1,707
1,454 - a = 1,707


14. The Sears Tower is 1,454 feet tall. Let the height of the antenna on the tower be represented by the variable a. The total height of the building plus the antenna is 1,707 feet. What is the height of the antenna? (Points : 1)
253 feet
353 feet
450 feet


15. Write an equation to represent the problem. The area of a triangle is equal to one half times the base times the height. Use A for area, b for base and h for height. (Points : 1)
A = 1/2 b + h
A = 1/2 (b + h)
A = (1/2) bh


16. Which equation represents the problem? The circumference of a circle equals the product of two, pi, and the radius. Use C for circumference, 3.14 for pi, and r for the radius. (Points : 1)
C = 2 + 3.14 + r
C = 2(3.14)r
C = (3.14r)/2


17. Which equation represents the problem? A cube has six sides, each of which is a square. If the measure of each side is s, what is the area of one side (square) of the cube? (Points : 1)
A = s^3
A = s^2
A = 6s^2


18. Write a formula for the entire surface area (all six squares) of a cube in simplest form. Let SA be the surface area and s is the measure of one edge of the cube. (Points : 1)
SA = s^3
SA = s^2
SA = 6s^2
