A rectangle has a perimeter of 18. The height of the rectangle is 4 cm. What is the area of the rectangle?

Answers

Answer 1

Answer:

20

Step-by-step explanation:

Perimeter of rectangle= 2l+2h so 2l+2(4)=18. SO 2l=10. l=5

Area=bh

(5)(4)=20cm

Answer 2
20 cm, I think
The perimeter is 18 and the height is 4 cm.

4 cm x 2 = 8
We are multiplying it by two because there are two side in a rectangle that are the same height

18 - 8 = 10
We are finding the length of the rectangle
10\2 = 5
The length of the rectangle is 5

5 x 4 = 20
That is the area

Lindas aunt zoe charges her a nominal amount for watching her two children aunt zoe charges $2.50 per day plus $1.75 per hour one day linda paid her aunt $14.75 how many hours did aunt zoe watch the children

Answers

Answer:

7 hours

Step-by-step explanation:

the function of the earning of Zoe = 2.50 + 1.75h

2.5 = base fixed amount

1.75 varies based on the hours

h = hours

2.50 + 1.75h = 14.75

to solve for h

subtract 2.5 from both sides and then divide by 1.75

14.75 - 2.5 = 1.75h

12.25 = 1.75h

h = 7

Mrs. Kemp began the school year with 20 students in her kindergarten class. She had 23 students at the end of the year. What was the
percent of increase in the number of students from the beginning of the year to the end of the year?

Answers

First, we’re going to use this formula:

2nd number - 1st number
————————————— x 100%
1st number


If we plug in the numbers to this equation:

23-20
———- x 100%
20

And subtract 23 to 20, the answer to this equation is:

3
—- x 100% = 15%
20

In this case, the percent of increase is 15%.

A swimming pool measures 10 feet by 8.5 feet by 5 feet. How many cubic feet of water will the swimming pool hold?

Answers

Answer:

425 Cubic Feet

Step-by-step explanation:

Cubic feet is volume meaning that in order to find the volume you must multiply the length, width and the height. The answer is 425

The swimming pool will hold 425 cubic feet of water.

What is the volume of a rectangular prism?

The volume of the rectangular prism is defined as the space in three-dimension covered by the rectangular prism having the sides Length, Width, and Height.

To find the volume of the swimming pool in cubic feet, we need to multiply the length, width, and height of the pool:

The volume is calculated as,

Volume = length x width x height

Volume = 10 ft x 8.5 ft x 5 ft

Volume = 425 cubic feet

Therefore, the swimming pool will hold 425 cubic feet of water.

mary need 50 ft of fence to protect her rectangular garden from squirrels. How long and how wide is the 8 ft more than the width length is if the length is 8 ft more than the width

Answers

Answer:

Width of the fence = 8.5 ft

Length of the fence = 16.5 ft

Step-by-step explanation:

Mary need 50 feet of fence to protect her rectangular garden from squirrels. How long and wide is the garden if the length is 8 feet more than the width?

Perimeter of the fence = 2(length + width)

Perimeter of the fence = 50 ft

Width of the fence = x ft

Length of the fence = x + 8 ft

Perimeter of the fence = 2(length + width)

50 = 2{(x+8) + (x)}

50 = 2(x + 8 + x)

50 = 2(2x + 8)

50 = 4x + 16

50 - 16 = 4x

34 = 4x

x = 34/4

x = 8.5

Width of the fence = x ft

= 8.5 ft

Length of the fence = x + 8 ft

= 8.5 + 8

= 16.5 ft

Width of a rectangle is equal to [tex]\boldsymbol{8.5}[/tex] feet and length is equal to [tex]8.5+8=\boldsymbol{16.5}[/tex] feet

Perimeter of a rectangle

A quadrilateral having four right angles is known as a rectangle. It can also be described as a square - shaped quadrilateral (equiangular meaning all angles are identical) or a parallelogram with a right angle.

Let [tex]x[/tex] denotes the width [tex](w)[/tex] of a rectangle.

So,

Length of a rectangle [tex](l)=x+8[/tex]

Perimeter of a rectangle [tex]=50[/tex] feet

[tex]2(l+w)=50\\l+w=25\\x+8+x=25\\2x=17[/tex]

[tex]x=8.5[/tex] feet

So,

width is equal to [tex]\boldsymbol{8.5}[/tex] feet and length is equal to [tex]8.5+8=\boldsymbol{16.5}[/tex] feet

Answers

Answer:

Decease in weight by 56.4%

Step-by-step explanation:

From 55 lb to 24 lb,

There is a decrease in the weight from 55 lb to 24 lb.

For the percentage decrease in weight,

Change in weight = 55 - 24

                              = 31 lb

Percentage change in weight = [tex]\frac{\text{Total change}}{\text{Initial value}}\times 100[/tex]

                                                  = [tex]\frac{31}{55}\times 100[/tex]

                                                  = 56.36%

                                                  ≈ 56.4%

Therefore, there is a decease in weight by 56.4%.

x = 31.4

PQ = 58.8

Step-by-step explanation:

Set up a proportion:

SQ/QP = ST/PR

Substitute in the values they give you:

[tex]\frac{x-9}{x-9+x+5} = \frac{8}{21}[/tex]

[tex]\frac{x - 9}{2x - 4} = \frac{8}{21}[/tex]

[tex]21x - 189 = 16x - 32\\5x = 157\\x = 31.4[/tex]

This means that PQ = 2x - 4 = 2(31.4) - 4 = 62.8-4 = 58.8

Answer:

x = 15, PQ = 26

Step-by-step explanation:

x+13/9 = 21/x-9

x^2+4x−117=168

x^2+4x−285=0

(x−15)(x+19)=0

x=15

it cannot be a negative number so x cannot be -19

If the probability of a cup drink being rasberry flavour is 0.29, what is the probability of a cup drink being cola flavour?

Answers

Answer: 0.71

Step-by-step explanation:

Since we have just two flavors, the probability of a cup drink being cola flavour will be calculated below:

P(R) + P(C) = 1

0.29 + P(C) = 1

P(C) = 1 - 0.29

P(C) = 0.71

Therefore, the probability of a cup drink being cola flavour is 0.71.
