heyy! i’ll give brainliest please help.

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

Your answer is C

Step-by-step explanation:

You should look at the exponent. Once you figure out the difference between the two exponents then you get your answer.

Number of sections = 9

Angle of each section = 360°/9 = 40°

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

Answer: Nancy = X , Anna = Y   X rule is plus 8 and Y rule is plus 12

Step-by-step explanation:

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

135degree

Answer:

Please check explanations

Step-by-step explanation:

Here, we want to describe transformation

As we can see, we added a value to the initial x and subtracted a value from the initial y

By adding to the initial x value, we are simply moving towards the right of the coordinate plane i.e we move towards the positive x axis

for the y axis value, we made a subtraction

what this mean is that we are actually going towards the negative y axis

So we move right on the positive x axis and move downwards to the negative y axis

Answer:

[tex]\dfrac{a+b+c}{a} =7[/tex]

Step-by-step explanation:

Given :-

And we need to prove that ,

So let us assume that ,

[tex]\dfrac{a+b}{3} =\dfrac{b+c}{6} =\dfrac{c+a}{5}=k[/tex]

Where k is a constant . Now equate each of the three terms separately to k . Therefore we have ,

[tex]\implies a + b = 3k \quad \dots (i) [/tex]

Similarly we can say that ,

[tex]\implies c + b = 6k \quad \dots (ii)[/tex]

[tex]\implies a + c = 5k\quad \dots (iii) [/tex]

Subtracting (i) and (ii) :-

Adding (iv) and (iii) :-

[tex]\implies 2c = 4k [/tex]

[tex]\implies \boxed{c = 4k }[/tex]

Put this is (ii) :-

[tex]\implies b +4k = 6k [/tex]

[tex]\implies \boxed{b= 2k }[/tex]

Similarly we will get ,

[tex]\implies \boxed{a = k }[/tex]

Proving the given equation :-

[tex]\implies \dfrac{a+b+c}{a} \\\\\implies \dfrac{k+2k+4k}{k} \\\\\implies \dfrac{7k}{k}=\boxed{\red{ 7}}[/tex]

Hence proved !

Given:

Original price = $145.00

Final cost = $152.25

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]

Therefore, the percent of tax is 5%.

Answer:

c

Step-by-step explanation:

Answer:

f = 2

Step-by-step explanation:

equate the log

therefore,

2f + 4 = 14 - 3f

collect like terms

2f + 3f = 14 - 4

5f = 10

divide through by 5

f = 10/5

f = 2

Answer:

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

Answer:

Percentage increase = 36%

Step-by-step explanation:

Kitten's weight = 640 grams

Adult's weight = 2918 grams

To find the percentage increase in the kitten's weight;

We will calculate the increase using the formula;

[tex] Increase = original \; number - new \; number [/tex]

Substituting the values, we have;

Increase = 2918 - 640 = 2278

Mathematically, percentage increase is calculated using the following formula;

[tex] Percentage \; increase = \frac{increase}{original \; number} * 100[/tex]

[tex] Percentage \; increase = \frac{2278}{640} * 100[/tex]

[tex] Percentage \; increase = 3.56 * 100[/tex]

Percentage increase = 35.5 ≈ 36%

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%
