Change in the amount of water in the bathtub after -48.75 gallons. Negative sign means water get reduce by 48.75 gallons in bathtub.
<h3><u>Solution:</u></h3>
Given that
A clogged bathtub drains at a constant rate.
The amount of water in the bathtub changes by –3.75 gallons in one hour.
Need to determine change in the amount of water in the bathtub after 13 hour.
Change in amount of water in bathtub in one hour = -3.75 gallons
As given that clogged bathtub drains at a constant rate, so
Change in amount of water in bathtub in 13 hours = 13 x Change in amount of water in bathtub in 1 hours
=> Change in amount of water in bathtub in 13 hours = 13 x ( -3.75 ) = -48.75 gallons
Hence change in the amount of water in the bathtub after -48.75 gallons. Negative sign means water get reduce by 48.75 gallons in bathtub.

Answer:
<h2>
35°</h2>
Step-by-step explanation:
This is an isoceles triangle
And as we all know an isoceles triangle has two equal base angles.
And we also know that the sum of all interior angles of the triangle is 180°
So based on this we can form an algebraic equation of solve for angke t (Let's do it :))
So the base angle is 35°
First we need to know both the formula of A and B.
The formula of A is
C = 5 + 0.25p
with C representing total cost and p representing the amount of checks.
The formula of B is
C = 6 + 0.15p
with C representing total cost and p representing the amount of checks.
To find the point where A and B cost the same, we solve the following equation:
5 + 0.25p = 6 + 0.15p
Collecting terms gives us
-1 = -0.1p
Now we have to divide by -0.1 and we get.
10 = p
p = 10
So our answer: after 10 checks both accounts cost the same amount of money. Answer A.
