Answer:
The ratio of student that completed their homework to the students who didn't complete their homework is 9:6 = 9 /6
Step-by-step explanation:
9 of 15 students completed their homework .The ratio of students who completed their homework to the ratio that didn't complete their's can be calculated below
The total number of student that was given the homework is 15 . Out of this 15 students only 9 of the students completed their homework. The remaining student out of the 15 didn't complete their's.
The remaining number of student that didn't complete their homework is 15 - 9 = 6 .
Therefore,
The ratio of student that completed their homework to the students who didn't complete their homework is 9:6 = 9 /6
The ratio can be further reduced to 3/2
(2x)/3 = 4
first multiply both sides by 3 to clear the fraction
2x = 12
next divide both sides by 2
x = 6
Answer:
Height=28
Step-by-step explanation:
You have to work backwards using the formula for a triangle, A=1/2bh
Plug your values in, 126=1/2 9 h
126=4.5 h
126 divided by 4.5 is 28

Problem 10
You are correct. The answer is choice C. The cm^3 notation represents cubic centimeters, which is a unit for volume. Think of a 1 cm by 1 cm by 1 cm cube.

Problem 11
This problem is a bit strange. She borrows money ($100) but then it says she earns $300 per day. It makes no mention of her paying that $100 back, or when it's due back. I'll just assume that she keeps the $100 for the 12 days.
If that assumption is correct, then she'll have y = 300x+100 dollars after x days.
Plug in x = 0 and you'll get y = 100. Plug in x = 12 and you'll end up with y = 3700. Therefore, the two points on this graph are (0,100) and (12,3700).
The only window that has y = 3700 in it is the interval 
while the other windows are too small. So only choice D is the answer here. In other words, you'll have "yes" on choice D, and "no" on everything else.
