the area of rectangular park is 3/5 square mile, the length of the park is 7/8 mile,what is the width of the park

Luba_88 [7]

Area=LengthxWidth so 3/5=7/8xWidth. To get width by itself you must divide both sides by 7/8. When dividing fractions you can flip the fraction and multiply so multiply (3/5)(8/7). To do this just multiply the numerators and denominators to get 24/35 so width = 24/35

Find the area of a rectangle that has the length of 2x-3 and the width of x .Someone painted an interior area of the rectangle a

Svet_ta [14]

Answer:

The area that was not painted is $(2x^{2}-6x+6)\ units^{2}$

Step-by-step explanation:

step 1

Find the area of the rectangle

we know that

The area of a rectangle is equal to

$A=LW$

In this problem we have

$L=2x-3$

$W=x$

substitute

$A=(2x-3)x\\A=(2x^{2}-3x)\ units^{2}$

step 2

Find the area that was painted

$A=(3)(x-2)\\A=(3x-6)\ units^{2}$

step 3

Find the area that was not painted

Subtract the area that was painted from the total area of rectangle

so

$A=(2x^{2}-3x)-(3x-6)=(2x^{2}-6x+6)\ units^{2}$

What is the volume of the following rectangular prism

zloy xaker [14]

Answer:

The volume of the rectangular prism is 7/8 u³

Step-by-step explanation:

1/2 u² = 0.5 u²

1 3/4 u = 1.75 u

To calculate the volume of a rectangular prism we have to use the following formula:

a = area = 0.5 u²

v = volume

h = height = 1.75 u

v = a * h

we replace the values that we know

v = 0.5 u² * 1.75 u

v = 0.875 u³ = 7/8 u³

The volume of the rectangular prism is 7/8 u³
