Answer:

Step-by-step explanation:

Hey there!

Well radius is half the diameter so,

D = r*2

Plug in 9

D = 9*2

D = 18

Hope this helps :)

Answer:

The answer is 18 feet

Step-by-step explanation:

To find the diameter of a circle given it's radius we use the formula

diameter = radius × 2

From the question

radius = 8

So the diameter is

<h3>diameter = 9 × 2 = 18 feet</h3>

Hope this helps you

In math, do you still distribute even the number is behind the parentheses?

The answer is YES!
You’re gonna have 10x+15+23
Then 10x + 38
And then you are doing next (2x+3) •5 + 23
So you have 2(5x+19)

Ryan invested his savings in two investment funds. The $24,000 that he invested in Fund A returned a 6% profit. The amount that

Viefleur [7K]

Answer:

the sum invested in Fund b is $6000

Step-by-step explanation:

This question can be easily solved using allegation Method.

Profit on fund A is 6% whereas Profit on fund B is 2%.

Fund A + Fund B= $24000

Overall profit to be gained = 5%

6% 2%

3 : 1

therefore the fund was distributed in the ratio 3:1

⇒4 units= 24000

⇒ 1 unit = $6000

therefore the fund A = 3×6000=$ 18000

and the fund B= 1×6000= $6000

Someone please help me with this

Answer:

50° is the correct answer

Step-by-step explanation:

Right Triangles

The right triangles are identified because they have an internal angle of 90°. The basic trigonometric ratios can be used to find angles and side lengths as needed.

We have a right triangle with the following characteristics:

The hypotenuse is 13 units long

The indicated angle is opposite to the leg of 10 units long.

When we know the length of the opposite side, we use the sine ratio. Let's call θ to the required angle:

$\displaystyle \sin\theta=\frac{\text{opposite side}}{\text{hypotenuse}}$

$\displaystyle \sin\theta=\frac{10}{13}$

Using a calculator set in mode degrees, the angle is:

$\theta=\sin^{-1}\frac{10}{13}$

$\theta\approx 50.3^\circ$

First choice: 52° is not correct because is not a good approximation to 50.3°

Second choice:38° is not correct because is not a good approximation to 50.3°

Third choice: 50° is a good approximation to 50.3°. Correct Answer

Fourth choice: 40° is not correct because is not a good approximation to 50.3°
