The fill-in for the answer tells you that translation takes place before reflection. To figure out how much translation is needed, you need to know the line of reflection.

You can look at the reflection choices to see where the line of reflection is. We're guessing that the only vertical line choice is the y-axis. (If the line of reflection is x=1, there doesn't need to be any horizontal translation.) If the image is reflected across the y-axis, the point R' moves from (-3, 0) to (3, 0). This is where R' is reflected from.

The point R is at (5, 2). To move R from (5, 2) to (3, 0) prior to reflection, the x-coordinate needs to decrease by 2 (from 5 to 3), and the y-coordinate also needs to decrease by 2 (from 3 to 0). That is, the point R must be translated left 2 and down 2 to get it to (3, 0).

R'S'T'U' is the image of RSTU after translation 2 left, 2 down, and reflection across the y-axis.

Answer:

40.5 cm²

Step-by-step explanation:

To find the triangles area on the tip of the crayon you do base x height ÷ 2 so 3 x 2 ÷ 2 = 3.

After, multiply 12.5 by 3 then add them both together to get 40.5 cm²

Answer:

Step-by-step explanation:

The correct solving of the decimal shows that 3.675 × 10 = 36.750, 3.675 × 100 = 367.5 and 3.675 × 1,000 = 3675.

How to solve the decimals?

From the information given, it should be noted the students calculations are incorrect. Therefore, 3.675 ×10 = 3.6750, 3.675 × 100 = 3.67500 and 3.675 × 1,000 = 3.675000 are incorrect.

In this case, when multiply by raise to power 10, it's important to shift the decimal based on the number being raised to power.

Therefore, 3.675 × 10 = 36.750, 3.675 × 100 = 367.5 and 3.675 × 1,000 = 3675.

Answer:

1/6 chance or 16.667% chance

Step-by-step explanation:

a fair number cube has six sides so if you roll that 30 times that's 180 sides and the probability of rolling a 2 out of a single dice is 1/6 and since 180 * 1/6 is equal to 30 that is 30 out of 180 which is 1/6

Answer:

95 inches

Step-by-step explanation:

First, we do 7 x 12(This is the conversion factor for feet to inches). Now we get 84 inches.

Second, we add 84 inches to the 11 inches that we haven't touched so far.

Now, we have 95 inches as your answer!

Answer:

scale factor = 2.5 and b` is now (0,10) and c` is (-15, 25)

Step-by-step explanation:

You first want to divide -15 and -6, the x values of a and a`. this will give you the scale factor. then multiply every other number by the scale factor to get the points for b` and c`.

If the radius is 6 the diameter is 12 so you begin solving your equation which makes it 37.7 and 113.0

Answer:

y = -2x

Step-by-step explanation:

Given

Solving

Rewriting the equation

New equation

⇒ y = mx + b [m = slope, b = y-intercept]

⇒ y = -2x + 0

⇒ y = -2x

Answer:

2x+y=0

Step-by-step explanation:

Given:

[tex]\displaystyle \large{2x+y=4}\\\displaystyle \large{y=-2x+4}[/tex]

To find:

Parallel Definition:

Slope-Intercept:

[tex]\displaystyle \large{y=mx+b}[/tex]

Therefore, another line is:

[tex]\displaystyle \large{y=-2x+b}[/tex]

Since the line passes through origin point which is (0,0). Substitute x = 0 and y = 0 in the equation:

[tex]\displaystyle \large{0=-2(0)+b}\\\displaystyle \large{b=0}[/tex]

Therefore, the equation is:

[tex]\displaystyle \large{y=-2x}[/tex]

Convert back to standards form:

[tex]\displaystyle \large{2x+y=0}[/tex]

Therefore, another line that is parallel to [tex]\displaystyle \large{2x+y=4}[/tex] is 2x+y=0

Answer:

363

Step-by-step explanation:

[tex]A = \pi r^2[/tex]

it says π is 3

so,

[tex]A = 3r^2[/tex]

r is the radius of the circle which is shown as 11

so,

[tex]A = 3*(11)^2[/tex]

Solve for A

[tex]A= 3* 121\\A= 363[/tex]

Answer:

0.15

Step-by-step explanation:

Area = [tex]\pi[/tex][tex]r^{2}[/tex]

Area of the shaded region = [tex]\pi 5^{2}[/tex]

Area = 78.5 [tex]in^{2}[/tex]

Area of the whole dart board = [tex]\pi r^{2}[/tex]

Area = [tex]\pi 13^{2}[/tex]

Area = 530.66[tex]in^{2}[/tex]

Probability = [tex]\frac{78.5}{530.66}[/tex]

= 0.1479 ≈ 0.15

Answer:

1/6

Step-by-step explanation:

if the chance is 6/36 for the first then the answer would be 1 in 6 to at least get a 5

Based on the probability of the number match, the probability of rolling at least 1 five is 1/6.

Probability is the possibility of an event happening or not.

It is also described as the chance or likelihood of an event happening or not.

In a cube, there are six faces numbered 1 to 6

The probability of rolling two number cubes whose numbers match is 6/36.

Then 5 is a number our of the six numbers.

Therefore, the probability of rolling at least 1 five is 6/36 or 1/6.

Answer:

Step-by-step explanation:

Two events are independent if the result of the second event is not affected by the result of the first event. If A and B are independent events, the probability of both events occurring is the product of the probabilities of the individual events.

Answer:

The first stpe in solving this system of equations is finding either X or Y in terms of the other variable. Ex: x = 8 - y or y = 8 - x

Step-by-step explanation:

When faced with a system of equations problem, you need to find one variable at a time. To do this, you need to eliminate one of the variables from one of the equations. I used x + y = 8 because that was simplier to find one of the variables from. From there, you can substitute that in for the variabel in the secone equation.

3x - 2y = -6

3x - 2(8 - x) = -6

3x - 16 + 2x = -6

5x - 16 = -6

5x = 10

x = 2

Than you can use that and plug it back into one of the original equations to find the other variable.

x + y = 8

2 + y = 8

y = 6

Answer:

40 times

Step-by-step explanation:

To figure this out, divide 6 by 30, then multiply by 200

(6/30)200 = 40

This also works: (200/30)6 = 40

We divide 6 by 30 because we landed on the 1 side 6 times out of 30. We then multiply 6/30 by 200 because it is out of 200 this time, so we will multiply 6 by 200 then divide by 30. 200(6) = 1200. 1200/30 = 40.
