The length of a rectangle is 3yd longer than its width. If the perimeter of the rectangle is 26 yd ,find its area

Answers

Answer:

A=40

Step-by-step explanation:

There are two sides of a rectangle that are the length.

So at 3 twice.

3+3=6

Subtract it from 26.

26-6=20

Divide by 4

20/4=5

Width= 5

Add 3 to 5

3+5=8

L=8

Check:

5+8+5+8=26

10+16=26

26=26

Area= L*W

8x5=40

A=40

The interior volume of a refrigerator is 25 cubic feet. The overall dimensions of the refrigerator are 50 inches by 35 inches by 69 inches. What is the approximate difference between the entire volume of the refrigerator and its interior volume?

Answers

Answer:

8725 cubic feet

Step-by-step explanation:

First, you have to figure out the volume of the refrigerator which your equation is:

length x width x height = volume

50 x 35 x 60 = 105,000 cubic inches

then you can transfer either inch to feet or feet to inch.

8750 cubic feet

to 25 cubic feet

So we have the equation 8750 - 25 = 8725 cubic feet

Answer:

The approximate difference between the entire volume of the refrigerator and its interior volume is 44.88 cubic feet

Step-by-step explanation:

What is volume?

Volume is a scalar quantity expressing the amount of three-dimensional space enclosed by a closed surface.

Given,

Interior Volume = 25 cubic feet = 43200 cubic inches

The Entire volume of the refrigerator is,

=50*35*69

=120750 cubic inches

Approximate Difference

=120750 - 43200 = 77550 cubic inches = 44.88 cubic feet.

The total cost to play paintball can be represented by the expression (48x+54). If Rocco and five friends split the cost equally, what is the cost for each person

Answers

Answer:

8x + 9

Step-by-step explanation:

The total number of people splitting the cost equally = Rocco and five friends = 6 people

The total cost to play paintball can be represented by the expression (48x+54)

The cost for each person is calculated as: The total cost to play paintball/ Total number of people

= (48x+54)/6

= 48x/6 + 54/6

= 8x + 9

Therefore, the cost for each person is

8x + 9

You and your friend each have a canvas of the same size. You divide your canvas into 5 sections and paint 3 of them. Your friend divides her canvas into 7 sections and paints 4 of them. Who paints more?

Answers

The one one paints 3/5, you would find a common denominator and it would be 21/35 and 20/35 so “you”

The person who paints more is given by the inequality equation 3/5 >  4/7

What is an Inequality Equation?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

Let the number of canvas be 35 ( LCM of 5 and 7 )

Now , when you divide 35 into 5 sections and paints 3 of them ,

The fraction A = 3/5

And , when your friend divide 35 into 7 sections and paints 4 of them

The fraction B = 4/7

And , the inequality equation is A > B

Substituting the values in the equation , we get

3/5 > 4/7

Hence , the one who paints more is you with 3/5 of the canvas

Water, along with important minerals, enters a plant from the soil where the plant's roots act like straws "drinking" it up. Carbon dioxide enters a plant from the atmosphere, and it comes in through the leaves. More specifically, carbon dioxide enters a plant through tiny pores or openings on leaves called stomata. Sunlight, obviously, comes from the sun. But how does it enter the plant to be converted into chemical energy that the plant can use? Well, green plants are green because of a pigment called chlorophyll.
