V = 19

First step : -76 + 4v = 4 × ( v - 19)

Second step: solve: 4 = 0

Second part 2: v - 19 = 0

Add 19 from both sides of the equation:

So, that's how I came up with "v" equaling to '19"

A swimming pool at a park measures 9.75 meters by 7.2 meters.

neonofarm [45]

Answer:

Part a) The area of the swimming pool is $70.2\ m^2$

Part b) The total area of the swimming pool and the playground is $105.3\ m^2$

Step-by-step explanation:

Part a) Find the area of the swimming pool

we know that

The area of the swimming pool is

$A=LW$

where

L is the length side

W is the width side

we have

$L=9.75\ m\\W=7.2\ m$

substitute the values

$A=(9.75)(7.2)$

$A=70.2\ m^2$

therefore

The area of the swimming pool is $70.2\ m^2$

Part b) The area of the playground is one and a half times that of the swimming pool. Find the total area of the swimming pool and the playground

we know that

To obtain the area of the playground multiply the area of the swimming pool by one and a half

$\frac{1}{2}(70.2)=35.1\ m^2$

To obtain the total area of the swimming pool and the playground, adds the area of the swimming pool and the area of the playground

$70.2\ m^2+35.1\ m^2=105.3\ m^2$

therefore

The total area of the swimming pool and the playground is $105.3\ m^2$

A gardener is planting two types of trees:

ICE Princess25 [194]

Answer:

After 1 year, both the tress will be of the same height.

Step-by-step explanation:

Let us assume in x years, both trees have same height.

Type A is 7 feet tall and grows at a rate of 8 inches per year.

⇒The growth of tree A in x years = x times ( Height growth each year)

= 8 (x) = 8 x

⇒Actual height of tree A in x years = Initial Height + Growth in x years

= 7 + 8 x

or, the height of tree A after x years = 7 + 8x

Type B is 9 feet tall and grows at a rate of 6 inches per year.

⇒The growth of tree B in x years = x times ( Height growth each year)

= 6 (x) = 6 x

⇒Actual height of tree B in x years = Initial Height + Growth in x years

= 9 + 6 x

or, the height of tree B after x years = 9 + 6x

According to the question:

After x years, Height of tree A =Height of tree B

⇒7 + 8x = 9 + 6x

or, 8x - 6x = 9 - 7

or, 2 x = 2

or, x = 2/2 = 1 ⇒ x = 1

Hence, after 1 year, both the tress will be of the same height.

sarita use 54 ounces of apples to make an apple pie how many pounds and ounces of apples did sarita use

LUCKY_DIMON [66]

One pound is 16oz. So you take 54 and minus it by 16 until you get something less that 16. Then you take how many times you subtracted it, and that is how many pounds. Then you take the "leftover" number and they you have your answer.
so Sarita used 3 pounds and 8 oz.
