Given:

[tex]OA=3[/tex] units

[tex]OA'=9[/tex] units

To find:

The scale factor of the dilation.

Solution:

From the given figure it is clear that the center of dilation is point O. Point A' is the image of point A. So,

[tex]\text{Scale factor}=\dfrac{OA'}{OA}[/tex]

Putting the given values, we get

[tex]\text{Scale factor}=\dfrac{9}{3}[/tex]

[tex]\text{Scale factor}=3[/tex]

Therefore, the scale factor of the dilation is 3.

Answer:

The value of the larger number is

[tex]x=24[/tex]

Step-by-step explanation:

A number, x, is 4 times another number, y.

[tex]x=4y[/tex] --------- (1)

The difference between the two numbers is 18.

[tex]x-y=18[/tex] -------(2)

Re-arranging equation (2) yields

[tex]-y=18-x\\y=x-18[/tex]------------- (3)

Substitute y=x-18 in equation (1)

[tex]x=4 (x-18)[/tex]

[tex]x=4x-72\\x-4x=-72[/tex]

[tex]-3x=-72\\x=\frac{72}{3}\\x=24[/tex]

Substitute x=24 in equation (3)

[tex]y=24-18\\y=6[/tex]

Answer:

C

Step-by-step explanation:

Step-by-step explanation:

Classroom A has n students.

Since Classroom B has 4 less students, they have (n - 4) students.

Also Classroom C has double the students in B, so they have 2(n - 4) students.

We have A + B + C = 40.

=> n + (n - 4) + 2(n - 4) = 40

=> n + n - 4 + 2n - 8 = 40

=> 4n - 12 = 40

=> 4n = 52, n = 13.

Hence there are 13 students in Classroom A.

Answer:

-6x

Step-by-step explanation:

23x+50x-79x

We take out x from the terms and group them up.

We therefore get (23+50-79)x after taking out x, and grouping the coefficients together.

Calculating 23+50-79 gets us -6, which is the coefficient of the final answer.

So the answer would be -6x.

Answer:

Step-by-step explanation:

C.) 32

Step-by-step explanation:

2^5 = 32

Answer:

C y>2/3x+3

Step-by-step explanation:

Use y=mx+b format. The B is the y-intercept. From the y-intercept (3), go up two then to the right 3. That gives you the slope, or mx which is 2/3. The area shaded is above so it would be the greater than symbol.  

Answer: x = 4 and y = -3

Step-by-step explanation:

2x + 4y = -4

2x = -4 - 4y

x = -2 - 2y

Now that we have solved the first equation for x, we plug (-2 - 2y) into the other equation in place of x and then solve for y.

3(-2 -2y) + 5y = -3

-6 - 6y + 5y = -3

-y = 3

y = -3

Now that we know y, we plug it into the original equation and solve for x.

2x + 4(-3) = -4

2x + -12 = -4

2x = 8

x = 4

You can check the answer by plugging both x and y into either of the original equations.

(-6, 4)

Answer:

x=-3

Step-by-step explanation:

2(-2x-8) + 4x = 2(1+3x)

Distribute:

-4x-16+4x=2+6x

Simplify Like-Terms:

-16=2+6x

Subtract 2 from both sides:

-18=6x

Divide both sides by 6:

x=-3

An acute angle is an angle that measures less than 90 degrees

Step-by-step explanation:

Answer:

One thing that is unclear here is whether the "1." at the start is part of the number "1.2" or if it is an enumeration of the question, and the base raised to the exponent is in fact 2.

The rest of the equation seems to indicate the latter, so we'll solve both:

If 1.2ᵃ ₓ 2⁵ = 2⁰, then a is approximately equal to -19.009.

If as I'm guessing is the correct question, 2ᵃ ₓ 2⁵ = 2⁰, then a is equal to -5.

Step-by-step explanation:

Interpretation #1:

[tex]1.2^a \times 2^5 = 2^0\\1.2^a \times 32 = 1\\1.2^a = \frac{1}{32}\\log_{1.2} \frac{1}{32} = a\\a \approx -19.009[/tex]

Interpretation #2:

Here the question is much simpler, as we need only add the exponents when adding and dividing:

[tex]2^a \times 2^5 = 2^0\\2^a = 2^0 \div2^5\\2^a = 2^{-5}\\a = -5[/tex]

Answer:

44

Step-by-step explanation:

Number who use balls only = 7 / 20

Number who use rings only = 3/7

Fraction who use both :

1 - (7/20 + 3/7)

1 - 0.7785714

= 0.2214285

If number of jugglers is less than 200

Number of jugglers who use both :

0.2214285 * 200

= 44.285714

Number of jugglers who use both should be about 44
