Answer:
15. 3 cups left
16. C. 158 miles
Step-by-step explanation:
15. Each 1/2 cup makes 6. He made 24. 24 divided by 6 is 4. So he used 4 times 1/2 a cup, or 2 cups. 5 - 2 = 3.
16. Each dot is a day that had that many miles. You add all the miles together.
10 × 2 = 20
10 1/2 × 1 = 10 1/2
11 × 3 = 33
11 1/2 × 4 = 46
12 × 3 = 36
12 1/2 × 1 = 12 1/2
Total is 158
Answer:
t=13
Step-by-step explanation:
the ratio of the shorter sides is t/4 and the ratio of the longer sides is 26/8 so t=26×4/8=104/8=13
Answer:
- 0.382 m/min
- 8 1/3 ft/s
Step-by-step explanation:
1. The rate of change of volume is ...
V = πr^2h
V' = πr^2h'
h' = V'/(πr^2) = (3 m^3/min)/(π(5 m)^2) = 0.12/π m/min
h' ≈ 0.382 m/min

2. In the attached, ∆PCM ~ ∆MXS, so we can write the proportion ...
x/9 = s/15 . . . . where x = BX and s = BS in the diagram
Multiplying by 15 gives ...
s = (15/9)x = (5/3)x
Then the rate of change is ...
s' = (5/3)x' = (5/3)(5 ft/s)
s' = 8 1/3 ft/s
The tip of the shadow is moving at 8 1/3 feet per second.
The answer is A. subtract 12 from both sides of the equation and then divide both sides by 4.
