60% of 15 is what answer

Answers

The correct answer is 9. :)

Answer:9

Step-by-step explanation:

Think of it this way:

If 15=100%

then x= 60%

So what you do is you multply 60 times 15 and divide it by 100 to give you the answer of 9. To me this is the simplest way to do it, I believe it’s called butterfly multiplying. You cross multiply and then you divide.

Answer:

y = (2/3)x + 7

Step-by-step explanation:

Slope intercept form is y = mx +b

1) We start off with y =

2) m = slope. Since we know that the slope is 2/3 we can plug it in. y = 2/3x

3) b is y-intercept which = 7.

Put it all together: y = 2/3 x + 7

The answer is

y = 2/3x +7

the graph of g(x) = x³ -9x² + 3x -1 is translated up 5 units to produce the graph of the function h(x). what would be the new equation of h(x)​

Answers

Answer:

h(x) = x^3 - 9x^2 + 3x + 4

Step-by-step explanation:

To write the new equation, we have to understand what the translation is about

What it means is that we are going to add the 5 units to the total value of the equation

we have this as:

h(x) = x^3-9x^2 + 3x-1 + 5

h(x) = x^3 - 9x^2 + 3x + 4

George has just purchased a small rectangular fish tank that holds 837 milliliters of water. The tank has a width of 6.2 cm and a
height of 9 cm.
What is the length of the fish tank?

Answers

Answer:

Step-by-step explanation:

Answer:

15 cm

Step-by-step explanation:

Area = Length ⋅ Width ⋅ Height

let's set:

Area: 837

Length: X

Width: 6.2 cm

Height: 9cm

837 = X ⋅ 6.2 ⋅ 9

First multiply 6.2 and 9 to get 55.8

Next divide 837 by 55.8 and you get 15

therefore, the length (x) is equal to 15
