terrance must decide which job offer to accept. one job pays $25 per hour for 37 1/2 hours each week and the other pays $825 per week regardless of how many hours he works. which job should terrance take? why?
Answers
Answer 1
Answer:
If the first job pays $25 per hour for 37 1/2 hours each week .. You have to multiply $25 & 37 then divide by 2. Then you will see that you get $462.5 each week . So Terrance would choose the second job because he would get paid more .
The height of a trapezoid is 8 inches and its area is 96 inches squared. One base of the trapezoid is 6 inches longer than the other base. What are the lengths of the bases? Explain how you found your answer.
Answers
Let the length of one base = x. Length of other = x + 6.
Area = (1/2)*(Sum of bases ) * height
96 = (1/2) *(x + x + 6) * 8
96 = (2x + 6) * 4
96/4 = 2x + 6
24 = 2x + 6
2x + 6 = 24
2x = 24 - 6
2x = 18
x = 18/2
x = 9.
Length of bases are x, and x + 6. 9 and 9+6 = 15.
Lengths of bases are 9 and 15 inches.
Marcie solved the following inequality, and her work is shown below: −2(x − 5) − 12 ≤ 4 + 6(x + 3) −2x + 10 − 12 ≤ 4 + 6x + 18 −2x − 2 ≤ 6x + 22 −8x ≤ 24 x ≤ −3 What mistake did Marcie make in solving the inequality?
The mistake is in the last step. she divided by -8 and she didn't chage the sign of inequality. When you multiply or divide by a negative number the sign of the inequality has to be changed.
The right step would show: x ≥ -3

look at the shape and see if you can make it into a cardboard box, then unfold the box and cut it into nice shapes that have areas taht are easy to find the area of like rectangles, triangles, circles, etc
