Answer:
<u>The correct answer is A. 12 minutes.</u>
Step-by-step explanation:
Let's solve for y, when x = 12, as follows:
y = 175 - 15x
y = 175 - 15 * 12
y = 175 - 180
y = - 5
This result means that after 12 minutes the fish tank would be completely drained and if it's needed 5 additional gallons of water could also be drained. It's not necessary to continue making more calculation with the the other options given because this is the right answer.
<u>The correct answer is A. 12 minutes.</u>
Answer:
Step-by-step explanation:
(-14) ÷ (-34)
14/34
= ⁷/17
Marissa wants to know how much she would make using the simple interest calculation.
She will have $4,432.35
Given data
Principal = $3,900
Time = 7 years 6 months = 7.5 years
Rate = 1.82%
I = A - P = $532.35
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 1.82%/100 = 0.0182 per year.
Solving our equation:
A = 3900(1 + (0.0182 × 7.5)) = 4432.35
A = $4,432.35
The total amount accrued, principal plus interest, from simple interest on a principal of $3,900.00 at a rate of 1.82% per year for 7.5 years is $4,432.35.
