If you would like to know what is the unit price for the hair shampoo, you can calculate this using the following steps:
500 ml ... $2.10
100 ml ...$x = ?
500 * x = 2.10 * 100 /500
x = 2.10 * 100 / 500
x = $0.42
The unit price for the hair shampoo is $0.42.
Correct Answer:
C option: 6 feetSolution:Since <span>Yolanda wants to keep the pool in proportion to the model, the ratio of diameter to depth of model and the pool will be same.
Let the depth of pool is x feet. So we can write:
Ratio of Diameter to Depth of Model = Ratio of Diameter to Depth of pool
</span>
![18:4=27:x \\ \\ \frac{18}{4} = \frac{27}{x} \\ \\ x=27* \frac{4}{18} \\ \\ x=6](https://tex.z-dn.net/?f=18%3A4%3D27%3Ax%20%5C%5C%20%20%5C%5C%20%0A%20%5Cfrac%7B18%7D%7B4%7D%20%3D%20%5Cfrac%7B27%7D%7Bx%7D%20%5C%5C%20%20%5C%5C%20%0Ax%3D27%2A%20%5Cfrac%7B4%7D%7B18%7D%20%20%5C%5C%20%20%5C%5C%20%0Ax%3D6%20)

This means the depth of pool should be 6 feet if </span><span>Yolanda wants to keep the pool in proportion to the model.</span>
Since 12 friends share four pizzas equally,
3 friends share a pizza equally.
Hence, each friend gets 1/3 of a pizza.
Answer:
k = -3
Step-by-step explanation:
F(x) has a positive slope
g(x) has a negative slope
Let x = -3
The y value goes from 1 to -3
g(x) = k⋅f(x)
-3 = k(1)
-3 = k
