Answer: 9 feet

Step-by-step explanation:

The minimum length of the design Jaunice will paint on the wall is 9 feet.

It is required to find the the minimum length.

A rectangle is a type of quadrilateral, whose opposite sides are equal and parallel. It is a four-sided polygon that has four angles, equal to 90 degrees. A rectangle is a two-dimensional shape

Given:

Area of rectangular section of her wall =76.5 ft.²

Height of the design = 8.5 feet.

We know that

Area of rectangle=length*breadth

Area = l*h

76.5   =8.5*l

l=76.5/8.5

l= 9 feet.

Therefore, the minimum length of the design Jaunice will paint on the wall is 9 feet.

Answer:

Luis paid 3/5 of the original price

Step-by-step explanation:

Luis purchased a laptop with a fractional discount of 2/5 of the original price.

When dealing with fractional parts of a whole, the sum of all parts must equal 1. With this in mind, we can say:

Paid price + Discount price = Original price

Or, equivalently:

paid fraction + discount fraction = 1

From the above relation, it follows that:

paid fraction = 1 - discount fraction

[tex]\displaystyle \text{paid fraction }=1-\frac{2}{5}[/tex]

[tex]\displaystyle \text{paid fraction }=\frac{5-2}{5}[/tex]

[tex]\displaystyle \text{paid fraction }=\frac{3}{5}[/tex]

Luis paid 3/5 of the original price

Answer:

Local governments in several states impose a local income tax. Local taxes are in addition to federal and state income taxes. Local income taxes generally apply to people who live or work in the locality. As an employer, you need to pay attention to local taxes where your employees work.

If the local income tax is a withholding tax, then you are required to withhold it from employee wages. Or if the local income tax is an employer tax, you must pay it.

Local income taxes are typically used to fund local programs, such as education, parks, and community improvement.

Answer:

30 5/6 square feet

Step-by-step explanation:

Answer:

30 5/6 square feet

Step-by-step explanation:

First you need to know how much she can paint in 1/5 hour. So you're going to be dividing mixed numbers. To do that you need to make 12 1/3 a fraction:

12*3=36

36+1=37

12 1/3= 37/3

Divide by 2. With fractions you flip the second and multiply

37/3 ÷ 2/1 = 37/3 *1/2

Multiply top by top bottom by bottom

37*1=37

3*2=6

37/6 is what she can paint in 1/5 hour

Now you need to multiply that by 5 (5/5= 1 which means a full hour)

So we use 5/1 to multiply by 5 in fraction form.

37/6 * 5/1

37*5=185

6*1=6

Now simplify (turn it back into a mixed number)

185/6= 185÷6

30 with a remainder of 5

Answer:

  4 < s < 20

Step-by-step explanation:

The triangle inequality requires that any side of a triangle must have a length that is between the difference and the sum of the lengths of the other two sides.

For unknown side s, the length must be ...

  (12 -8) < s < (12 +8)

  4 < x < 20

__

Additional comment

The triangle inequality is usually written ...

  a + b > c . . . . . for any assignment a, b, c to side lengths

If s is not the longest side, then we require ...

  s +8 > 12   ⇒   s > 4

If s is the longest side, then we require ...

  8 +12 > s   ⇒   s < 20

__

Some authors write the inequality as ...

  a +b ≥ c

This allows a "triangle" that looks like a line segment. It will have an area of 0. If your curriculum uses this version of the triangle inequality, then the answer to this question will be 4 ≤ s ≤ 20.

Answer:

4:24

Step-by-step explanation:

The ratio of the number of students who bike to school to the number of students that do not bike to school is 1:6.

The ratio is the division of the two numbers.

For example, 20/5 is the ratio while x ∝ 10 is the proportion.

Proportion is the relation of a variable with another. It could be direct or inverse.

Given,

Total number of students = 28

Number of students that bike to school = 4

So,

A number of students that do not bike to school = Total number of students - Number of students that bike to school.

Number of students that not bike to school = 28 - 4 = 24

So, the ratio of the number of students that bike to school to the number of students that do not bike to school = 4/24 = 1/6.

Hence, The ratio of the number of students that bike to school to the number of students that do not bike to school is 1: 6.

Answer:

20.25 kg

Step-by-step explanation:

Set up a proportion, where x is the number of kg in the barbell

[tex]\frac{1}{0.45}[/tex] = [tex]\frac{45}{x}[/tex]

Cross multiply:

x = 45(0.45)

x = 20.25

So, there are 20.25 kg in the barbell

Answer:

the barbell weighs 20.25 kg

Step-by-step explanation:

It's quite easy to find the answer! All you have to do is multiply .45 kg by 45!

so the equation would be:

0.45 x 45 = 20.25

Answer:

(1) 3 to 11

Step-by-step explanation:

Ratio of pennies to nickels is 8 to 3.

Pennies : nickels = 8 : 3

Pennies = 8

Nickels = 3

Total coins = pennies + nickels

= 8 + 3

= 11

Which of the following is the ratio of nickels to the number of all the coins?

Nickels : Total coins = 3 : 11

Or

= 3 / 11

Or

3 to 11

The correct answer is (1) 3 to 11

Answer:

The factory can make 3 witch costume from 18 buttons

The factory can make 7 witch costume from 42 buttons

The factory can make 11 witch costume from 66 buttons

The factory can make 14 witch costume from 84 buttons

Step-by-step explanation:

Let us use the ratio method to complete the table

∵ A factory needs 6 buttons to make 1 witch costume

∵ There are 18 buttons

→ Find how many witch costume can make from them

→ Buttons → costume

→  6           →  1

→  18          →  x

→ By using cross multiplication

∵ x × 6 = 18 × 1

∴ 6x = 18

→ Divide both sides by 6

∴ x = 3

∴ The factory can make 3 witch costume from 18 buttons

Use the same way to find the rest

∵ There are 42 buttons

→ Buttons → costume

→  6           →  1

→  42         →  x

→ By using cross multiplication

∵ x × 6 = 42 × 1

∴ 6x = 42

→ Divide both sides by 6

∴ x = 7

∴ The factory can make 7 witch costume from 42 buttons

∵ There are 66 buttons

→ Buttons → costume

→  6           →  1

→  66         →  x

→ By using cross multiplication

∵ x × 6 = 66 × 1

∴ 6x = 66

→ Divide both sides by 6

∴ x = 11

∴ The factory can make 11 witch costume from 66 buttons

∵ There are 84 buttons

→ Buttons → costume

→  6           →  1

→  84         →  x

→ By using cross multiplication

∵ x × 6 = 84 × 1

∴ 6x = 84

→ Divide both sides by 6

∴ x = 14

∴ The factory can make 14 witch costume from 84 buttons

The only ones are on the "diagonal", where i = j. Else the position is simply the sum.

The amount that he owes after one year is 1792.09 dollars. Then the correct option is C.

The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

Rodney owes $1,541.05 on his credit card.

His card has an APR of 16.29%, compounded monthly.

Assuming that he makes no payments and no purchases.

He owes after one year will be

Amount = 1541.05 × 1.1629

Amount = 1792.087 ≅ 1792.09

Answer:

Solutions:

Z = 35

C = 10

Systems of Equations:

Z = 3C + 5

C = Z - 25

Step-by-step explanation:

Z will be for Zayn and C will be for Cleo.

Z = 3C + 5

C = Z - 25

These are the systems of equations. To solve, plug one of the equations into their respected variable.

Z = 3(Z - 25) + 5

Z = 3Z - 20

20 = 2Z

Z = 10

C = 3C + 5 - 25

-2C = -20

C = 10

This proves that these equations are correct. To find the final solution, plug 10 into Z to find Zayn's amount , then plug the amount that was for Zayn into C to find Cleo's amount.

Z = 3(10) + 5

Z = 35

C = 35 - 25

C = 10
