Given :

Initial entrance fee of tennis class, E = $100 .

Fee of every month, F = $10 .

To Find :

How much will it cost for five months.

Solution :

Let, number of months are n and cost of class is y.

So, linear equation is given by :

y = 10n + 100       ...1)

To know the cost of 5 month, putting value of n = 5 in equation 1) we get :

y = ( 10×5) + 100

y = 50 + 100

y = $150

Therefore, the cost of five month fee in tennis class is $150.

Hence, this is the required solution.

The sides of the triangle occur in a ratio of 4 : 7 : 2, so if x is some positive number, then we can write each side's length in terms of x as 4x, 7x, and 2x.

The perimeter is 299 yd, so

4x + 7x + 2x = 299 yd

13x = 299 yd

x = (299 yd) / 13

x = 23 yd

Then the sides of the triangle have lengths of

4x = 4 • 23 yd = 104 yd

7x = 7 • 23 yd = 161 yd

2x = 2 • 23 yd = 46 yd

"Median" here refers to the side length between the shortest and longest sides, so the answer would be 104 yd.

Answer:

8x

Step-by-step explanation:

Because you are adding the (x+3) there you can immediately you the association property to simplify

(2x + 5x + x) + (3 - 3)

8x + 0 =

8x

Answer:

bottom right is correct

Step-by-step explanation:

Let r be the mass of a red disc and b the mass of a blue disc.

7 blues have the same mass as 1 red along with a 5 kg mass, so

7b = r + 5

7b - r = 5

2 blues and 1 red have the same mass as a 4 kg mass, so

2b + r = 4

Solve for b and r . Notice that adding the equations together eliminates r :

(7b - r) + (2b + r) = 5 + 4

9b = 9

b = 1

Then

7 • 1 - r = 5

r = 7 - 5

r = 2

So each red disc has a mass of 2 kg, and each blue disc has a mass of 1 kg.

Answer:

$65 + $(-25) = $40

$65 - $25 = $40

Step-by-step explanation:

Profit made last week = $65

Profit made this week = - $25

Addition expression for her profit over the two weeks

Last week profit + this week's profit:

$65 + $(-25) = $40

Subtraction expression for her profit over the two weeks :

$65 - $25 = $40

Answer:

40

Step-by-step explanation:

4/5 * q = 32

First you divide 4/5 by itself so you can eliminate it from the equation and then you have to divide 32 by 4/5 n when you do that you get 40. So q = 40.

Answer: [tex]\frac{6}{2}[/tex]

Step-by-step explanation:

1. Use this [tex]\frac{f(b)-f(a)}{b-a}[/tex] to find the average rate of change

2. Average rate of change = [tex]\frac{f(8)-f(6)}{8-6}[/tex]

3. [tex]f(8) = - 4[/tex] and [tex]f(6) = -10[/tex] (To find these you will need to look at the points on the graph. So the points (8,-4) and (6,-10))

4. Replace -4 to f(8) and -10 to f(6)

5. So it will look like[tex]\frac{-4-(-10)}{8-6}[/tex]

6. Solve [tex]\frac{6}{2}[/tex]

They both have same height,

let the height of both triangles be = x

let the base one triangle = y

then the base of another trainlgle = 2y

Area of triangle = 1/2 X B X H

Area of Triangle 1

[tex] \frac{1}{2} \times y \times x \\ = > \frac{xy}{2} [/tex]

Area of Triangle 2

[tex] \frac{1}{2} \times 2y \times x \\ = > \frac{2xy}{2} \\ = > xy[/tex]

Difference in the area =

[tex]xy - \frac{xy}{2} \\ = > \frac{2xy - xy}{2} \\ = > \frac{xy}{2} [/tex]

Hence Area of Triangle 1 is half the area of Triangle 2

Difference of 1/2 area.

Area of triangle = 1/2 X B X H

Area of Triangle 1

\begin{gathered} \frac{1}{2} \times y \times x \\ = > \frac{xy}{2} \end{gathered}21×y×x=>2xy

Area of Triangle 2

\begin{gathered} \frac{1}{2} \times 2y \times x \\ = > \frac{2xy}{2} \\ = > xy\end{gathered}21×2y×x=>22xy=>xy

Difference in the area =

Hence Area of Triangle 1 is half the area of Triangle 2

Difference of 1/2 area.

Answer:

163

Step-by-step explanation:

262-99=163

Answer:163

Step-by-step explanation: subtract 262 and 99

Answer:

37%

Step-by-step explanation:

First, we need to know that 1 student equals 1 percent.

If 37 students chose pineapple, than it would be 37%

(Some times, you have lets say... 75 students, so you would do 75, subtracted from 74 (Or one less), to get how much one student is.)

Answer:

$104.31

Step-by-step explanation:

First let's calculate the sale price of the shoes. If they are 24% off, that means they will be worth 76% of the initial price. So, we can multiply 76% by 129 to find the sale price:

129 * 0.76 = 98.04

The sale price is $98.04. To find the value of the sales tax, multiply the sale price by the percentage of the sales tax:

98.04 * 0.064 = 6.27456

The sales tax rounds to 6.27. Finally, to find the total price, add the value of the sales tax to the sale price:

98.04 + 6.27 = 104.31

The total price Zach will pay is $104.31.

Answer:

The mean should be D. 5

Step-by-step explanation:

The mean means the average which in this order (4, 5, 6) The direct middle is 5, making it the average since there are only 3 numbers in the first place.

You can mark out A (2) and B (3) instantly because they are lower than any of beginning numbers, and it's not C (4) as 'mean' doesn not mean the lowest, which leaves you with D (5)

Answer:

What caused the differences in their behavior? The food coloring in cool water remained at the bottom of the container. ... The behavior of the food coloring was caused by the movement of heat through the water and the formation of convection currents. The warmer water is less dense, so it rises to the surface.

Answer:

The odds against making a free throw are: 0.1905 or 0.16:0.84

Step-by-step explanation:

The odds can be categorized into two categories

The odds against is the ratio of probability of failure to probability of success.

Given

Probability of making a free throw = P = 0.84

Probability of not making a free throw = Q = 1-P = 1-0.84 = 0.16

The formula for odds-against is:

[tex]Odds-against = \frac{0.16}{0.84}\\= 0.19047..\\=0.1905[/tex]

Hence,

The odds against making a free throw are: 0.1905 or 0.16:0.84
