21^2 + 28^2 = Hypotenuse^2
441 + 784 = 1225
sqrt (1225) = 35
hypotenuse = 35
Answer:
75 gallons
Step-by-step explanation:
15gal PER 1 min
__gal PER 5 mins
To solve this, I would do 15 x 5. That gets me to 75 gallons.
Hope this helps :D
Formula for area of rectangle:
A=L x w
Here A=85 square ft
Length, L=w+12
Put values in formula.
85=(w+12)w
85=w^2+12w
Subtract 85 from both sides
w^2+12w-85=0
Factorise the equation.
(w-5)(w+17)=0
w=5 and w=-17
Ignore the negative value of width.
Width, w= 5 ft and Length, L=12+5=17 ft
Answer: Width=5 ft and Length=17 ft
The answer is C due to the fact that 3^2 is 9 which is 9pi and its the same as 28.26
The answer is B. If you multiply it you get the original problem.
