Last summer, the Abrams family had a 30-gallon baby pool that they could fill in just 2
minutes. This summer, they purchased a larger kiddie pool that holds 150 gallons of water.
If the Abrams fill the larger pool at the same rate, how long will it take to fill it?
Answer:
10 mins
Explanation:
Because it takes 2 minutes to fill a 30 gal pool, and 150/30=5, 2 x 5 = 10 giving you the answer of 10 mins to fill a 150 gal pool.
Time taken to fill the larger kiddie pool that holds 150 gallons of water is 10 minutes.
Given that, the Abrams family had a 30 gallon baby pool that could fill in just 2 minutes.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Now, rate of filling the pool = 30/2
= 15 gallons per minute
So, time taken to fill 150 gallons of water
= 150/15
=10 minutes
Therefore, time taken to fill the larger kiddie pool that holds 150 gallons of water is 10 minutes.

Phillipe says he cannot simplify the expression 5^c • 2^c. Complete the statement about Phillipe's claim.
Answer:
Step-by-step explanation:
[tex]a^{m} * b^{m}[/tex] = [tex](ab)^{m}[/tex]
Yes, he can!!
[tex]5^{c} * 2^{c} = (2 * 5 )^{c}[/tex] = [tex]10^{c}[/tex]
For example,

6³ = 216
The expression can not be simplified as it do not have same base, and can be written as [tex]10^c[/tex]
What is an expression?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.
Given that, Phillips says he cannot simplify the expression [tex]5^c.2^c[/tex]
She can not simplify the expression because the bases of the expression are not same, and this expression is same as

Step-by-step explanation:
The angles of a triangle add to 180, add the angles and solve for x
Answer:
x = 14
Step-by-step explanation:
3x + 9 + 5x - 1 + 4x + 4 = 180 because triangles have 180 degrees
12x + 12 = 180
180 - 12 = 168
12x = 168
168/12 = 14
x = 14

Answer: I'd go with C. Winter, because sleet is made from snow, which forms when it is cold
Step-by-step explanation:
Hailstones form when the updrafts generated by thunderstorms (which are more common in spring and summer than winter) quickly lift water droplets high in the troposphere, where they freeze at very low temperatures, then fall. Sleet occurs when falling snow melts and then refreezes before it hits the ground.
