If 30% of a number is 15, what is 25% of the number?

Answers

Answer 1

Answer:

12.5

Step-by-step explanation:

Basically, the number was multiplied by .3 to get 15. So if you do 15/.3 you'll get your original number which is 50. Then you multiply by .25 and get 12.5.

Answer and Step-by-step explanation:

A. Cruz is correct.

B. When we have a negative within a cube root, what we can do is move the negative sign from inside to outside the cube root.

[tex]\sqrt[3]{-64} = -\sqrt[3]{64}[/tex]

Now that we have a positive number within the cube root, we can solve the cube root itself.

So what is the cube root of 64?

The answer is 4, and since we have a negative sign outside of the cuberoot, we just put a negative sign, our answer is -4.

C. Aaron could've got it wrong because he did it a square root instead of a cuberoot of 64. Square root of 64 is 8, while cube root is 4.

Jacob could've gotten it wrong because he must've followed the fallacy that you cannot cube root a negative number.

A triangle has a perimeter of 15 feet. Side B is one foot longer than side A. Side C is two feet longer than side A. What is the length of each side.

Answers

Answer:

Side A = 4

Side B = 5

Side C = 6

Step-by-step explanation:

In the following equation, variable a is the length of Side A

a + (a + 1) + (a + 2) = 15

a + a + a + 1 + 2 = 15

3a + 3 = 15

     - 3    - 3

3a (÷ 3) = 12 (÷ 3)

a = 4

Side A = 4

Side B = (a + 1) = (4 + 1) = 5

Side C = (a + 2) = (4 + 2) = 6

the length of the unknown leg is?

Answers

Answer:

a = 10

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is qual to the sum of the squares on the other 2 sides, that is

a² + 24² = 26²

a² + 576 = 676 ( subtract 576 from both sides )

a² = 100 ( take the square root of both sides )

a = [tex]\sqrt{100}[/tex] = 10

what is the equation of the following? Someone could help me to understand this? thank you​

Answers

Answer:

y=(1/5)x

Step-by-step explanation:

First, we must find the slope of the line.

The slope of a line can be found using the formula: (y2-y1)/(x2-x1)

(3-0)/(15-0)

(3)/(15)

1/5

The slope is 1/5.

Next we find the y-intercept, or where the line crosses the y-axis. In this case, the y-intercept is 0.

This gives us the equation: y=(1/5)x
