Part of the proceeds from a garage sale was $470 worth of $10 and $20 bills. If there were 14 more $10 bills than $20 bills, fin
Brums [2.3K]

There are 25 $10 bills and 11 $20 bills.

Step-by-step explanation:

Given,

Worth of proceeds from garage = $470

Let,

x be the number of $10 bills

y be the number of $20 bills.

According to given situation;

10x+20y=470       Eqn 1

x = y+14                Eqn 2

Putting value of x from Eqn 2 in Eqn 1

10(y+14)+20y=470\\10y+140+20y=470\\30y=470-140\\30y=330

Dividing both sides by 30

\frac{30y}{30}=\frac{330}{30}\\y=11

Putting y=11 in Eqn 2

x=11+14\\x=25

There are 25 $10 bills and 11 $20 bills.

How to find surface area of a right triangular prism to the nearest whole number?
vovangra [49]
The area of the two triangular bases is
  (total base area) = 2×(1/2)bh
    = bh
    = (10 m)(6 m) = 10·6 m² = 60 m²

The area of the three rectangles making up the remaining faces of the prism is
  (total lateral area) = length×base + length×height + length×hypotenuse
    = length×(base + height + hypotenuse)
    = (16 m)(10 m + 6 m + 11.6 m)
    = (16 m)(27.6 m) = 16·27.6 m² = 441.6 m²

Then the surface area of the prism is the sum of these
  surface area = total base area + total lateral area
    = 60 m² + 441.6² = 501.6 m²
When rounded to the nearest whole number, this is
  A) 502 m²
