Volume is approximately 502.65 cm^2
Answer:
Step-by-step explanation:
total money = $2.25 = 225 cents
types of denomination in coins or cents are dimes and nickels
dime = 10 cents , nickel = 5 cents
twice of dimes to nickels
let no of dimes = x and no of nickels = y
our equation
10x + 5y = 225
x = 2y
10(2y) + 5y = 225
20y +5y = 225
25 y = 225
y=9
x =2y 2x9 = 18
so the number of dimes = 18 and nickels = 9
cross verification:
10x18 + 5x9 = 180 +45 = 225
Answer:
y=3x-2
Step-by-step explanation:
y-4=3(x-2)
y-4=3x-6
y=3x-2
Divide the shape into 2 rectangles:
Area = Length x width
1 : 7 x 30 = 210
2: (25 -7) x (30-20) = 18 x 10 = 180
Total area = 210 + 180 = 390 square feet.
