Hi I need help with this problem. But it has to be shown with work. Does anyone know?
x : 6 = 10 : 150

Answers

Answer 1

Answer:

its is 90

Step-by-step explanation:

6x10=60    150-60=90

Answer 2

Answer:

0.4 or 2/5???

Step-by-step explanation:

I believe this is a proportion/ratio problem.

Think of it like this:

x/6 = 10/150

To solve for x, you must cross multiply:

150x = 6*10 (150x... DON'T write 150*x, that is nonsense)

150x = 60

     x = 60/150  (you divide because you are actually dividing 150 on both sides and doing the opposite operation of multiplication)

     x = 6/15

     x = 2/5 or 0.4  (I simplified it)

Hopefully this helped? I can't seem to find a whole number answer... so the only options I could do are 2/5 or 0.4

Kara works at a fine jewelry store and earns commission on her total sales for the week. Her weekly paycheck was in the amount of $7000, including her salary of $1000. Her sales for the week totaled $50,000. Express her rate of commission as a percent, rounded to the nearest whole number.

Answers

Her total paycheck minus her salary = the commission amount
So
6500 - 1000 = 5500
So....her commission as a percentage of sales = 5500/ 45000 = about 12.2%

Answer:B or 540 cubic inches.

Step-by-step explanation:

So, if we multiplied all 3 values using the volume formula, we get 600 cubic inches. And if it says 90%, we multiply .9x600 and get 540 cubic inches.

Answer:

B. 540 cubic inches

Step-by-step explanation:

Let's start with the formula.

[tex]Volume=Length*Width*Height[/tex]

Or:

[tex]V=L*W*H[/tex]

We are given the Length, Width, and Height.

So we just multiply it out:

[tex]12.5*6*8=600[/tex]

The volume is 600 cubic inches

But we aren't done yet:

We now have to find 90% of 60, and we can do that in two ways

Set up a percent proportion:

[tex]\frac{x}{90}=\frac{600}{100}[/tex]

[tex]x=\frac{90*600}{100}[/tex]

[tex]x=540[/tex]

Or we could use benchmark fractions.

To find 90% of 600, we do 600 - (10% of 600)

This is just 600 - 60

540
