Answer:
557
Step-by-step explanation:
you multiply the square of the radius times the height and that would give you the volume
L = 2w + 4 , l + w = 80
solve using subsitiution.
(2w + 4) + w = 80
simplify / combine common
3w + 4 = 80
subtract 4 from both sides
3w = 76
divide by 3
w = 25 1/3 in
80 - 25 1/3 = 54 2/3
is it true that 54 and 2/3 inches is 4 inches more than two times 25 1/3? Yes.
Length = 54 and 2/3 inches
W = 25 and 1/3 inches
hope this helps ;D
Answer:
5 in^2.
Step-by-step explanation:
Volume = area of the base * height
30 = area of the base * 6
area of the base = 30/6 = 5 in^2.
Take the increase between the two numbers, then divided the increase by the original number then multiple by 100 . It should be 60%
Răspuns:
125%
Explicație pas cu pas:
a și B sunt invers proporționale cu numerele 12 și 15
Proporționalitate inversă:
a = k / y
Prin urmare ;
a = k / 12 - - - (1)
b = k / 15 - - - (2)
Procent care reprezintă a de la b
a = 100%
b = x
k / 12 = 1
k / 15 = x
Înmulțirea încrucișată:
x * k / 12 = k / 15
x = k / 12 ÷ k / 15
x = k / 12 * 15 / k
x = 15/12
x = 1,25
1,25 * 100% = 125%
