Answer:

7.5%

Step-by-step explanation:

Cost of memory card including tax = $138.89

Cost of memory card only = $129.20.

Cost of tax on memory card = Cost of memory card including tax - Cost of memory card only

= $138.89 - $129.20

= $9.69

Cost of tax on memory card = $9.69

What percent sales tax did he pay.

Percent of tax = Cost of tax on memory card / Cost of memory card only

= $9.69 / $129.20 × 100

= 0.075 × 100

= 7.5%

Percent of tax = 7.5%

Answer: B. 49 inches

Step-by-step explanation:

Circumference is calculated by 2πr, where r is radius. Radius is 8 inches, so the circumference is 2(3.1415)(8) ≈ 49 inches.  

Number of sections = 9

Angle of each section = 360°/9 = 40°

Answer:

Upper left coordinate (-8,8),

upper-right coordinates (-3,8)

Lower left (- 8, 5)

Lower right = ( - 3, 5)

Step-by-step explanation:

Given that :

Upper left coordinate (-8,8),

upper-right coordinates (-3,8).

x1, y1 = (-8, 8) ; x2, y2 = (-3, 8)

The distance, d = √(x2-x1)² + (y2 - y1)²

d = √(-3 + 8)² + (8 - 8)²

d = √25

d = 5

Recall :

Area = length * width

Length = distance, d

15 = 5 * w

15 = 5w

w = 15 / 5

w = 3.

Hence, coordinate becomes ;

x3, y3 becomes (- 8, (8-3)) = (-8, 5)

x4, y4 becomes (-3, (8-3)) = (- 3, 5)

Hence, we have

Upper left coordinate (-8,8),

upper-right coordinates (-3,8)

Lower left (- 8, 5)

Lower right = ( - 3, 5)

Answer:

Step-by-step explanation:

Pet sitters charge $25 to $30 a day on average, depending on the services involved. The average cost of a 30-minute visit is $25, while overnight pet-sitting costs $75 to $85

A clock has 12 hours on it.

360/12 = 30

Each hour is 30 degrees.

3pm to 7:30pm is 4.5 hours

Multiply total hours by degrees per hour:

4.5 x 30 = 135 degrees

Answer:

135 degree

Step-by-step explanation:

difference of 3pm to 7:30 is 4 hrs 30 min

12hrs=360degree

60min=360degree

4×360/12

=120

360/12×60×30

360×30÷720

15

now

120+15

Answer:

10 classes

Step-by-step explanation:

Given equations in the question

Dance World: y = 15x

Toe Tappers: y = 25 + 12.5x

Where,

x = number of classes

Equate the total cost at both dance studios

15x = 25 + 12.5x

Collect like terms

15x - 12.5x = 25

2.5x = 25

Divide both sides by 2.5

2.5x / 2.5 = 25 / 2.5

x = 10 classes

x = number of classes = 10

Answer:

b. 75°

Step-by-step explanation:

By exterior angle theorem:

3x = x + 70°

3x - x = 70°

2x = 70°

x = 70°/x

x = 35°

Therefore, 3x = 3*35° = 105°

Answer:

Surface Area Formula for a Rectangular Prism: A = 2( wl + hl + hw)

w = width

l = length

h = height

In this picture, it shows that the height is 4, the width is 2, and the length is 3. Therefore, we have:

A = 2 [ (2*3) + (4*3) + (4*2) ]

A = 2(6 + 12 + 8)

A = 2(26)

A = 52

Thus, the surface area is 52 cm^2.

Answer:

$137.75

Step-by-step explanation:

question is 'what is 5.8% of 2375'

'what' means assign a variable

'is' means an equal sign

'of' means to multiply

p = .058 x 2375

p = 137.75

*You could do the following:  p = 5.8 x 2375 and get 13775 but you have to remember to move the decimal point two places to the left

This questions asks you to find how that how long will it take until to fill the cone if 1,413 [tex]cm^{3}[/tex] of water goes in it every minute.

First, you have to find the volume of the cone:

V = 1/3 r^2 Pi * h

V = 1/3 * 60^2 * 150

V = 1/3 * 36000 * 471

V = 565, 200 [tex]cm^{3}[/tex]

If 1,413 [tex]cm^{3}[/tex] of water goes every minute into the cone, you will have to divide the volume by 1413 : 565, 200:1413 = 400

Therefore, it will take 400 minutes.

Answer:

x=3

Step-by-step explanation:

firstly this equation isn't possible without it equaling to something. I set it equal to zero and got x=3.

EX:

(x-3)^(3)=0

Answer:

x = -5

Step-by-step explanation:

each curve will get increasingly closer to -5 but never reach it

if you look at the function, f(x) = 3/(x+5),  x≠ -5 because then the denominator would be zero and that is never possible

The vertical asymptote of the function will  be [tex]x=-5[/tex].

A vertical asymptote is a vertical line i.e. as approaches from either the positive or negative side, the function approaches infinity. Vertical asymptotes occur at the values where a rational function has a denominator of 0.

We have,

[tex]f(x)=\frac{3}{x} +5[/tex]

So,

As the above definition says,

A Vertical asymptote of a function is a vertical line [tex]x=k[/tex], where [tex]f(x)[/tex] becomes unbounded.

So,

Vertical asymptote for given figure and given function is ,

[tex]x=-5[/tex],

Hence we can say that the vertical asymptote of the function will  be [tex]x=-5[/tex].

To find:

The percent of tax.

Solution:

The formula for tax is:

Tax = Final cost - Original price

[tex]\text{Tax}=\$152.25-\$145.00[/tex]

[tex]\text{Tax}=\$7.25[/tex]

Formula for tax percentage is:

[tex]\text{Tax percent}=\dfrac{\text{Tax}}{\text{Original price}}\times 100[/tex]

[tex]\text{Tax percent}=\dfrac{7.25}{145.00}\times 100[/tex]

[tex]\text{Tax percent}=\dfrac{725.00}{145.00}[/tex]

[tex]\text{Tax percent}=5[/tex]

Step-by-step explanation:

Answer:

The image of the window can be seen below:

In the image we can see that the window can be separated in:

One rectangle of 4ft by 5 ft

Two half-circles (that if we add we get a complete circle) of diameter D = 4in.

First, we know that for a rectangle of length L and width W, the area is:

A = L*W

Then the area of our rectangle is:

A = 4ft*5ft = 20ft^2

And for a circle of diameter D, the area is:

A' = 3.14*(D/2)^2

In this case we have D = 4in, then the area of the circle (that we get when we add the areas of the two half-circles) is:

A' = 3.14*(4ft/2)^2 = 3.14*4 ft^2 = 12.56 ft^2

Then the total area of the window is:

Area = A + A' = 20 ft^2 + 12.56 ft^2 = 32.56 ft^2

And we know that each square foot of glass costs $12, then  32.56 square foots of glass will cost  32.56 times $12

Then the total cost is:

C = 32.56*$12 = $390.72
