Which of the following solves the proportion 3/8 = x/24?

2 answers:

3 0

The answer is 9. If you multiply the denominator of the first fraction by 3, you get the denominator of the second fraction. To find the top number of the second fraction, you also have to multiply the numerator by 3. Therefore the answer would be 9.

24 / 8 = 3

This shows that 8 was multiplied by 3 to get 24.

3 * 3 = 9

Now, we know that 9 solves the proportion. (x = 9)

To check, we can simplify 9/24.

9/24 → 3/8

Hope This Helped! Good Luck!

5. Use the law of Cosines to find each missing sides. Round to the nearest tenth

stellarik [79]

The measure of angle x will be 88 degrees. Then the correct option is C.

The complete question is attached below.

<h3>What is law of cosine?</h3>

Let there is a triangle ABC such that |AB| = a units, |AC| = b units, and |BC| = c units and the internal angle A is of θ degrees, then we have:

2ab cos θ = a² + b² – c²

The triangle is shown below.

Then the value of the variable x will be

2 · 7 · 10 · cos x = 7² + 10² – 12²

140 · cos x = 49 + 100 – 144

cos x = (149 – 144) / 140

x = 87.95 ≈ 88°

Then the correct option is C.

Which statement accurately describes how to perform a 90° counterclockwise rotation of point A (−1, −2) around the origin? Creat

Anastaziya [24]

Answer:

last one

Step-by-step explanation:

You are swinging A(-1,-2) around the center which in this case is the origin. Keep in mind that points on a circle all have a equal distance from the origin. We don't want the distance from the center to change.

We want the center of that circle to be the origin.

So the answer is the last one:

"Create a circle with the origin as its center and a radius of the origin and point A, then locate a point on the circle that is 90° counterclockwise from point A. "
