You are planning the running shoe merchandise levels for your shoe store. Last year, your running shoe sales were down 10% from the previous season. The store had projected sales of 900 pairs of running shoes. Calculate the number of units the 10% sales decline represents.

Answers

Answer:

90

Step-by-step explanation: by taking 10% off of 900, you get 810; meaning 90 was subtracted

The number of units the 10% sales decline represents is 90

what is percentage?

In mathematics, a percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%"

Given here projected sales = 900 but the actual sales is 10% less than this amount , thus  actual sales = 900 - 10% of 900

                                             = 900 -( 10/100 )×900

                                             = 900 - 90

                                             = 810  

 Hence,  the number of units the 10% sales decline represents is     900-810 =90

how to solve this one​

Answers

Answer:

x= -7 and y=37

Step-by-step explanation:

substitute y=-26-9x in -2x-y=12

-2x-(-26-9x)=12

-2x+26+9x=12

-2x+9x=12-26

7x= -14

x= -14/2

x= -7

substitute x=-7 in y=26-9x

y= -26-9x

y= -26-9(-7)

y= -26+63

y=37

x= -7 and y=37

3 times 1 = 3

4 times 1/10 = 0.4

3 times 1/1000 = 0.003

200 + 3 = 203

Which of the following is the best approximation of the volume of the cylinder below?

Answers

Answer:

B

Step-by-step explanation:

[tex]v = \pi {r}^{2} h \\ = 8 \\ v = \pi {8}^{2} \times 3 = 3.14 \times 64 \times 3 = 602.88 = 602.9[/tex]

The volume of the cylinder is 2411.5 cm³ in the given figure. which is the correct answer would be an option (A).

What is the volume of a cylinder?

The volume of a cylinder is equal to the product of the area of the circular base and the height of a cylinder.

V = πr²h

where 'r' is the radius of the base (circle) of the cylinder

'h' is the height of the cylinder

As per the given figure,

The radius of a cylinder is 16 cm and the height of the cylinder is 3 cm.

The volume of a cylinder = πr²h

The volume of a cylinder = π(16)² × 3

The volume of a cylinder = 3.14(256) × 3

The volume of a cylinder = 2411.5 cm³

Thus, the volume of the cylinder is 2411.5 cm³ in the given figure.

Sara is building a triangular pen for her pet rabbit. If two of the sides measure 8 feet and 15 feet, the length of the third side could be
1) 13 ft
2) 7 ft
3) 3 ft
4) 23 ft

Answers

Answer:

1) 13 ft

Step-by-step explanation:

1) 13+8=21 which is greater than 15. Would be a triangle.

2) 7+8=15   This would be a single line, not a triangle.

3) 3+8<15   This would be a single line, not a triangle.

2) 15+8=23   This would be a single line, not a triangle.

The solution to the quadratic equation is x = -6 ± 2√7

What is Quadratic Equation?

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

x² + 12x + 25 = 17

Subtracting 17 on both sides , we get

x² + 12x + 8 = 0

And , roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

On simplifying , we get

x = ( -12/2 ) ± √ ( 12 )² - 4 ( 1 ) ( 8 ) / 2

x = -6 ± √ ( 144 - 32 ) / 2

x = -6 ± √112/2

And , the value of x = -6 ± 2√28/2

x = -6 ± 2√7

Hence , the solutions are x = -6 + 2√7 and -6 - 2√7

If the simple interest on 3,000​$ for 3 years is ​450$​, then what is the interest​ rate?

Answers

Answer/Step-by-step explanation:

The interest rate is 15% for every 3 years. To find the interest rate subtract the money from the total. Then, divide the total from the difference. Now subtract the quotient from 100 and multiply it by 100 to fin the percentage.

3000 - 450 = 2550

2550 ÷ 3000 = 0.85

100 - 0.85 = 0.15

0.15 x 100 = 15%
