Answer:
The rate is
cups per hour
Step-by-step explanation:
It took the faucet 1 1/2 hours equivalent 3/2 hours to fill 1/4 cup by leaking
We need to find the rate in terms of cups that can be filled by water in 1 hour.
Using unitary method:
it takes
for
cup
it will take 1 h for how many cups?
![= \frac{1 \times \frac{1}{4} }{\frac{3}{2} }= \frac{2}{4 \times 3}= \frac{2}{12}= \frac{1}{6} cups](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B1%20%5Ctimes%20%5Cfrac%7B1%7D%7B4%7D%20%7D%7B%5Cfrac%7B3%7D%7B2%7D%20%7D%3D%20%5Cfrac%7B2%7D%7B4%20%5Ctimes%203%7D%3D%20%5Cfrac%7B2%7D%7B12%7D%3D%20%5Cfrac%7B1%7D%7B6%7D%20cups)
Hence, the rate is
cups per hour
Answer:
A. b+2(b+2b)
b + 2b + 4b = 7b
B. 3b + b = 4b
C. 2(2b) = 4b
None of them are equal to 9b
Answer:
15 km/h
Step-by-step explanation:
To find the speed, divide the total number of kilometers by the total number of hours:
Find the total number of hours:
32 + 13
= 45
Divide this by 3:
45/3
= 15
So, the average speed was 15 km/h
Answer:
Step-by-step explanation:
∠A = arctan(33/43) ≈ 37.5°
AB = √(43² + 33²) = √2938
Law of Sines
∠C = arcsin(sinA ⋅ AB/BC) ≈ 34.7°
