Answer:

$17.60

Step-by-step explanation:

Jackie went to the store and bought 2 1/4 pounds of apples at $5 per pound

1 pounds = $5

2 1/4 pounds = x

x = 2 1/4 × $5

x = 9/4 × $5

x = $45/4

x = $11.25

9 pounds of pears at $2.35 per pound.

1 pound = $2.35

9 pounds = x

x = 9 × $2.35

x = $21.15

Total amount that she spent =

$11.25 + $21.15

= $32.40

If she paid with a $50 bill, how much change did she receive?

The change she received =

$50 - $32.40

= $17.60

A right triangular prism has a height of 3 ft, a width of 4 ft, and a hypotenuse of 5 ft. The depth of the triangle is missing.
DiKsa [7]
Depth=15
x=(height(h)*width(w)*hypotenuse(y))/2
x=(3*4*5)/2=(60/2)=30
y=(x(x-h)(x-w)(x-y))^(1/2)
f=(-h^4+2(hw)^2+2(wy)^2-w^4+2(hy)^2-y^4)^(1/2)
f=(-3^4+2(3*4)^2+2(4*5)^2-4^4+2(3*5)^2-5^4)^(1/2)
f=576^(1/2)
f=24
Surface Area= 2f(.5)+(h+w+y)*depth
192=depth*(3+4+5)+24(.5)
180=(3+4+5)*depth
180=(12)(depth)
15=depth

1. Avital counted 40 green cars and 20 silver cars in the parking lot. If the number of green cars stay the same, how many more
Luba_88 [7]
X represents the number that would be added to the silver cars.


x/40= 4
X=40x4
x=160

Subtract the given 20 from 160 because 160 is the total number
160-20=140
Therefore 140 would be added to 20 silver cars to get the ratio1:4

Anne has an aquarium in the shape of a rectangular prism that measures 10 in. By 20 in. By 10 in. How many cubic inches of water
kaheart [24]

Answer:

Volume = 2000\ in^3

Step-by-step explanation:

Given

Dimension: 10in by 20in by 10in

Required

Determine the capacity of the aquarium

This question implies that, we calculate the volume of the prism and this is calculated by multiplying the dimensions of the aquarium. i.e.

Volume = Length * Width * Height

Substitute values for the dimensions

Volume = 10 * 20 * 10

Volume = 2000\ in^3

Hence, the volume of the aquarium is 2000 cubic inches
