Answer:

because 18 times 100 is equal to 5 times x, which means that x is equal to 360

Step-by-step explanation:

18/5=x/100

Cross product

18*100=5*x

1800=5x

x=1800/5

x=360

because 18 times 100 is equal to 5 times x, which means that x is equal to 360

[tex]\fbox{\begin{minipage}{10em}Option C is correct\end{minipage}}[/tex]

Explanation:

A circle whose center is [tex](a, b)[/tex] and radius [tex]r[/tex], has equation:

[tex](x - a)^{2} + (y - b)^{2} = r^{2}[/tex]

The center of circle is  given as origin [tex](0, 0)[/tex], therefore:

[tex]a = 0\\b = 0[/tex]

This circle passes [tex](3, 0)[/tex], then the radius of circle is the distance [tex](d)[/tex] between origin [tex](0, 0)[/tex] and [tex](3, 0)[/tex]

[tex]d = \sqrt{(0 - 3)^{2} + (0 - 0)^{2} } = \sqrt{3^{2} } = 3[/tex]

=> [tex]r = d = 3[/tex]

Substitute [tex]a[/tex], [tex]b[/tex], and [tex]r[/tex] back into original equation:

[tex](x - 0)^{2} + (y - 0)^{2} = 3^{2}[/tex]

or

[tex]x^{2} + y^{2} = 9[/tex]

Hope this helps!

Answer :

A linear function has a graph in the shape of a line

A non-linear function does not have the same value added to or subtracted from the dependent variable

Step-by-step explanation:

A linear function is any function that graphs to a straight line.

So, The shape of linear graph is straight line .

1) A linear function has a graph in the shape of a ____

Answer : C . Line

Thus A linear function has a graph in the shape of a line

A nonlinear function is a function that is not linear. That is, for a fixed change in the independent variable, there is NOT a corresponding fixed change in the dependent variable

Non-linear means the graph is not a straight line. The graph of a non-linear function is a curved line.

2) A non-linear function 2_____ have the same value added to or subtracted from the dependent variable

Answer B : Does not

Thus A non-linear function does not have the same value added to or subtracted from the dependent variable

Answer:

x = 6

Step-by-step explanation:

The scale factor is

28/8 = 7/2

We take the ratio of the larger side over the smaller side

Using ratios we can find the sides

28         21

----- = ---------

8           x

Using cross products

28x = 21*8

28x =168

Divide each side by 28

28x/28 = 168/28

x =6

Answer:

x=-1

Step-by-step explanation:

3(x+5)=12

Step 1: Simplify both sides of the equation.

3(x+5)=12

(3)(x)+(3)(5)=12(Distribute)

3x+15=12

Step 2: Subtract 15 from both sides.

3x+15−15=12−15

3x=−3

Step 3: Divide both sides by 3.

3x

3

=

−3

3

x=−1

Answer:

x = -1

Step-by-step explanation:

3(x+5)=12

Divide each side by 3

3/3(x+5)=12/3

x+5 = 4

Subtract 5 from each side

x+5-5 = 4-5

x = -1

Answer:

First find how much bananas are in a dozen

15 x 12 = 180

Divide the amount by the amount of bananas per dollar to find profit

180 / 2 = $90

Do the same thing as before

15 x 12 = 180

180 / 3 = $60

Find how many bananas are left

180 + 180 = 360

540 - 360 = 180

Do the same as before

180 / 5 = $36

Add up all the money. 90 + 60 + 36 = 186

Subtract the cost

185 - 150 = 36

To find percentage increase

36 / 150 = 0.24 or 24% profit

Step-by-step explanation:

Answer:

RT ≈ 16.48 units

Step-by-step explanation:

The measure of arc RT is calculated as

RT = circumference of circle × fraction of circle

    = 2πr × [tex]\frac{118}{360}[/tex]

    = 2π × 8 × [tex]\frac{118}{360}[/tex]

     = 16π × [tex]\frac{118}{360}[/tex] ≈ 16.48 ( to the nearest hundredth )

The length of the arc RT is 8.23 units.

The characteristics of a circle's arc are:

Since angle RST is 118 degrees, it subtends 118/360 = 0.3278 (rounded to four decimal places) of the full circumference of the circle. Therefore, the length of arc RT is:

length of arc RT = (0.3278) * (2 * π * radius)

where the radius is half the length of RS. Since RS is given as 8 units, the radius is 4 units. Substituting this into the formula, we get:

length of arc RT = (0.3278) * (2 * π* 4) = 2.0684 * π

Rounding to the nearest hundredth, we get:

length of arc RT ≈ 8.23 units.

Answer: x = 2

5x - 2 = 10 - x

Add x to both sides.

6x - 2 = 10

Add 2 to both sides.

6x = 12

Divide both sides by 6.

x = 2

Step-by-step explanation:

5x - 2 = 10 - x

5x + x = 10 + 2

10x - 6 = 10

Answer:

6.5

Step-by-step explanation:

If M is the midpoint of PQ, PM is congruent to MQ. Midpoint means middle. So, the midpoint divides PQ in half. PQ = 13, and 13/2 = 6.5.

If In triangle PQR, PQ = 13, QR = 14, and PR = 15.  M is the midpoint of QR.  PM is: 12 cm.

In △PQR

M=Midpoint of side QR

PM =Median of the  iangle

Using Apollonius theorem

PQ ² +PR ² =2PM ² +2QM ²

13²+14²=2PM ² +2(1/2QR) ²

169+196=2PM ²+2(6)²

169+196=2PM ²+2(36)

365=2PM ²+ 72

2PM ²=293

Divide both side by 2

PM ²=293/2

PM ²=146.5

PM=11.97 cm

PM=12 cm (Approximately)

Therefore PM is 12 cm.

Answer: Option D.

Step-by-step explanation:

Out of the 15 simulations, the number with a 1 in them is 7. (are the sets of 5 shots that have at least one 3-pointer)

So out of 15 sets, 7 of them have at least one 3-point in them.

the experimental probability is p = 7/15.

So the correct option is D.

Step-by-step explanation:

substitute the value of y in terms of x

-2x - 3(6x-11)= -7

-2x - 18x+ 33=-7

-20x= -40

x = -40/-20
