X = bessie and y = betty
x + y = 1464
y = 2x - 375
x + 2x - 375 = 1464
3x - 375 = 1464
3x = 1464 + 375
3x = 1839
x = 1839/3
x = 613 <== Bessie gave 613 gallons
y = 2x - 375
y = 2(613) - 375
y = 1226 - 375
y = 851 <== Betty gave 851 gallons
Answer:
480 cubic feet
Step-by-step explanation:
Given length of self storage = 8 feet
width of self storage = 6 feet
height of self storage = 10 feet.
Volume of rectangular object is calculated by formula
volume = length * width * height
substituting the value of length , width and height of self storage room in above formula we have
volume of self storage room = 8 * 6* 10 cubic feet= 480 cubic feet
Answer:
9^3 times 7^2
Step-by-step explanation:
The simple interest accrued is = $750
<h3>Calculation of simple interest</h3>
The principal amount of the loan = $7500
The rate at which the interest is paid is = 2.5%
The time that it will take to pay the interest = 4 years
Using the formula for Simple interest;
SI= P×T×R/100
SI = 7500×4 × 2.5/100
SI= 75000/100
SI=$750
Therefore, the interest accrued on a $7500 loan with a 2.5% interest rate over 4 years is = $750

F(x)=-5t^2+20t+60
Divide everything by -5
f(x)=t^2-4t-12
(t-6)(t+2)
Set it up to zero
t-6=0. t+2=0
t=6. t=-2
Since you can’t have negative seconds, the answer is 6 seconds
