Which are equivalent ratios to 2:3?
Check all that are true.

10:16

8:12

6:9

9:12

4:6

Answers

Answer 1

Answer:

8:12 6:9 4:6

Step-by-step explanation:

Divide each ratio by 2:3 and check if both numbers on either side of : are the same

For example:

8:12 divided by 2:3 = 4:4

Answer 2

Answer:

8:12, 6:9, and 4:6

Step-by-step explanation:

Equivalent ratios are any ratios that represent the same when they are simplified. All the ratios above simplify to 2:3. When the 8 and 12 of 8:12 are both divided by 4, the result is 2:3. When the 6 and 9 in 6:9 are both divided by 3, the result is 2:3. When the 4 and 6 in 4:6 are both divided by 2, the result is 2:3. The ratios 10:16 and 9:12 cannot be simplified to 2:3, and therefore are not correct answers.

which of these would be a helpful first step in solving the equation? check all that apply. 7x - 9 = 2x + 21

Answers

Answer: E. Subtract 2x

Step-by-step explanation:

Subtracting 2x would remove a bit from both equations, giving us 5x - 9 = 12. This would make it easier now that we only have one number on a side.

Hope this helps!

what is the volume of the figure below

Answers

Answer:

665 ft^3

Step-by-step explanation:

The formula to find the volume of pyramids is 1/3 x length x width x height. One way to solve this is by multiplying the length, width and height, and then dividing it by 3.

14 x 9.5 x 15 = 1995

1995 / 3 = 665

So the volume is 665 cubic feet

I hope this helps :)

What is the value of x in the figure? Enter your answer in the box.

Answers

Answer:

x = 65

Step-by-step explanation:

(2x +15)= 145

      -15      -15    subtract 15 from each side

2x = 130130/2 = 65  therefore x=65
Okay so these are vertical angles, which means that they are going to be equal to each other, aka CONGRUENT.

This means that your equation is going to be:

2x + 15 = 145

Now let us solve that equation.
You are going to subtract 15 from each side, so subtract 15 from 15, and subtract 15 from 145, meaning that your new equation is going to be:

2x = 130

Now your are going to divide each side my 2. This means you are going to divide 2x by 2 and divide 130 by 2. This means:

x= 65.

Answer: -28 degrees Celsius

Step-by-step explanation:

Equation: -20 = t + 8 or t = -20 + -8 (t represents the temperature at midnight).

Using the second equation given, add the two numbers together. Since adding a negative is the same as subtracting a positive, subtract 20 from 8 and make it negative. The answer is -28.

Use your answer from Question #5 and the coordinates of P to find the coordinates of P’. Explain your work, including how the scale factor was used to determine the answer.

Answers

Answer:

Scale factor is used to find the coordinates depending upon whether the scale factor value is less than one or more than one.

Step-by-step explanation:

A scale factor is a number which scales, or increases, some amount. In the condition y = Cx, C is the scale factor for x. C is likewise the coefficient of x, and might be known as the steady of proportionality of y to x.

An object is augmented if the scale factor is more noteworthy than 1. An article is decreased if the scale factor is a division, under 1. To discover the expanded picture, we initially should know the directions of our unique picture. At that point we basically increase the arrange by the scale factor to discover the widened picture.
