Is this right? I chose 15.

Is This Right? I Chose 15.

Answers

Answer 1

Answer:

Correct, it is 15

Step-by-step explanation:

Because 3 turns into 9, you also want to multiply the other by 3, so you’d do 5x3 to get 15

Answer 2

Answer:yes you are correct. The answer is 15

Step-by-step explanation:

You would have to do 9/3=x/5. If you simplify that it would be 3x=45. If you simply further, you would get x=15 so yes you are correct.

Its A because the ratio from females to males ls 5:3

Answer:

B. He should focus on females because the ratio of females to males is 5:2.

Step-by-step explanation:

By looking at the graph, you can see that there are 25 females and 10 males. The ratio for this is 25:10, but we can simplify by dividing both sides by 5! 25/5=5, and 10/5=2, so the simplified ratio of 25:10 is 5:2. If you look at all of the answer choices, you really don't have to look at the words a lot; there's only one choice that includes the ratio 5:2. That choice is B, so B is the answer!

Find the length of side b in the right triangle below. Round to the nearest tenth if necessary A. 8
B. 16
C. 32
D. 64​

Answers

Answer:

A

Step-by-step explanation:

Use the Pythagorean Theorem( a^2 + b^2 = c^2(hypotenuse)

6^2 + b^2 = 10^2

36+b^2 = 100

b^2 = 64

b = 8(Use square root rule)

A

Hope this helps!  Have a nice day!

Answer:

8

Step-by-step explanation:

Use pythagorean therom: a^2 + b^2 = c ^2

6^2 + b^2 = 10^2

36 + b^2 = 100

b^2 = 64

square root both sides to get rid of the ^2

sqaure root of 64 = 8

square root of b^2 = b

b = 8

Suppose that y is directly proportional to x, and y = −16 when x = −2. What is the constant of proportionality?

A) −8
B) −
1
8
C) 1
8
D) 8

Answers

Answer:

In the given expression the constant of proportionality is  k = 8.

Step-by-step explanation:

The quantity P is said to be directly proportional to Q if they vary in proportion to each other.


Here, P ∝ Q ⇔  P = kQ : k = Proportionality Constant


Now, here given y ∝ x   and x =  -2, y = -16

Now, y ∝ x ⇒  y =  kxor, (-16)   = k (-2) or, k = 16/2  = 8 ⇒ k = 8So, for k = 8, y ∝ x 

Hence, in the given expression the constant of proportionality is  k = 8.

The graph represents function 1, and the equation represents function 2:

A coordinate plane graph is shown. A horizontal line is graphed passing through the y-axis at y = 4.

Function 2
y = 8x + 12

How much more is the rate of change of function 2 than the rate of change of function 1?

3
4
5
8

Answers

Answer:

Option D.

Step-by-step explanation:

The slope of a horizontal line is 0.

It is given that the function 1 is a horizontal line that passing through the y-axis at y = 4.

It means the rate of change of function 1 is 0.

The slope intercept form of a linear function is  1

where, m is slope and b is y-intercept.

The function 2 is  2

On comparing (1) and (2), we get

The rate of change of function 2 is 8.

The difference between rate of change is

The rate of change of function 2 is 8 more than the rate of change of function 1.

Therefore, the correct option is D.

d
