using geometry, we can find that the triangles are proportional, so if 8:24::5:15. 24/8=3, so do 5×3

Answer:

the equation to find the slope is (y2-y1)/(x2-x1)

the points are (-1,2) and (2,2) so plug it in and you get

(2-2)/(2-(-1))

0/ (2+1)

0/3

whenever the numerator is 0, that means the slope is 0. the line is just a horizontal line.

Answer:

$6.25

Step-by-step explanation:

Each football costs the same amount, and each basketball costs the same amount.

Let the cost of:

Footballs = f

Basketballs = b

Hence, we have the following system of equations

At the first store, the coach paid $110 for 5 footballs and 14 basketballs.

5f + 14b = 110

At the second store, the coach paid $82.50 for 10 footballs and 6 basketballs.

10f + 6b = 82.50

What was the cost in dollars of each basketball?

5f + 14b = 110..... Equation 1

10f + 6b = 82.50.....Equation 2

We solve using Elimination method.

Multiply Equation 1 by 10 and Equation 2 by 5 to eliminate f

50f + 140b = 1100.... Equation 3

50f +30b = 412.5.......Equation 4

Subtract Equation 4 from Equation 3

110b = 687.5

b= 687.5/110

b = $6.25

Therefore, the cost of one basketball in dollars = $6.25

[tex]\displaystyle x=\frac{39}{10}[/tex]

The midpoint of a line bisects that line into two congruent line segments - otherwise speaking, they are equivalent to each other.

Due to this, we can set the equations equal and solve for x.

First, set the equations equal to one another.

[tex]17x = 7x + 39[/tex]

Subtract 7x from both sides of the equation to combine like terms.

[tex]17x - 7x = 7x - 7x + 39[/tex]

[tex]10x =39[/tex]

Then, divide both sides of the equation by 10 to isolate the variable.

[tex]\displaystyle \frac{10x}{10} = \frac{39}{10}[/tex]

[tex]\displaystyle x=\frac{39}{10}[/tex]

Answer:

A, C, E

Step-by-step explanation:

The required relation whose constant of proportionality matches with the constant of proportionality given in the graph.

Given that,
A curve is shown in the graph, it is to be determined that the constant of proportionality of the curve matches one of the curves given in the options.

Proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense that are they directly proportional or inversely proportional to each other.

Here,
Constant of proportionality  for the given function,

y/x = 2 / 8 = 0.25

Since the constant of proportionality of the functions mentioned in Option A, C and E matched with the given graph.

Thus, the required relation whose constant of proportionality matches the constant of proportionality is given in the graph.

Answer:

Answer:

you found the value of x, just put it in the equation

The coordinates of point S is (4, -15)

The given parameters are

T = (0, 5)

Midpoint = (2, -5)

The midpoint of a line is calculated using

Midpoint = 1/2 * (x1 + x2, y1 + y2)

So, we have

(2, -5) = 1/2 * (0 + x, 5 + y)

This gives

(4, -10) = (x, 5 + y)

Solve for x and y

So, we have

x = 4

5 + y = -10

This gives

x = 4

y = -15

Hence, the coordinates of point S is (4, -15)

The capacity of thumb drive disc is 4 gigabytes and the capacity of compact disc is 2 gigabytes.

Let thumb drive = (x)

Let the capacity of 1 compact disk = (y).

Therefore, the appropriate equation will be:

4x + y = 18

4x + 3y = 22

Subtract the equations

2y = 4

y = 4/2

y = 2

The capacity of compact disc is 2 gigabytes.

Since 4x + y = 18

4x + 2 = 18

4x = 18 - 2

4x = 16

x = 16/4

x = 4

The capacity of thumb drive disc is 4 gigabytes.

Answer:

153 185-32 is 153 so there's your answer

Solution :-

given that,

→ Cost of meal before tax = $ 40

and,

→ Tax = 8.5%

So,

→ Total tax paid = 8.5% of cost of meal = (40 * 8.5)/100 = $ 3.4

now,

→ Tip = 18% of cost of meal = (18 * 40)/100 = $ 7.2

then,

→ Total cost of the meal = Cost of meal before tax + Total tax paid + Tip = 40 + 3.4 + 7.2 = $50.6 ≈ $51 (Ans.)

Shortcut :-

→ Total cost of the meal = Cost of meal * (100% + 8.5% tax + 18% tip) = 40(1 + 0.085 + 0.18) = 40 * 1.265 = $50.6 ≈ $51 (Ans.)

Answer:

  no, y does not vary directly with x

Step-by-step explanation:

If there is direct variation, the constant of variation can be found as ...

  k = y/x

Here, those ratios are ...

  y/x = 6/3 = 2

  y/x = 18/6 = 3

  y/x = 24/8 = 3

The ratio of y to x is NOT A CONSTANT, so there is no direct variation.

The radius of the circle will be 7.5 cm. Then the correct option is A.

It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

If the chord is passing through the origin. Then the chord will be the maximum chord and the maximum chord is known as the diameter of the circle.

A is the center of the circle, and the length of the CD is 15 centimeters.

The length CD is the diameter of the circle.

The length of the radius is calculated as,

AC = d / 2

AC = 15 / 2

AC = 7.5 cm
