A limited-edition soccer ball costs $30, and the sales tax is 6%. What is the total cost?

frez [133]

Answer:

$31.80

Step-by-step explanation:

The ball will cost 100% of its price plus 6% of its price for a total of 106%.

To use percentages as a factor and multiply, they must be divide by 100, making the multiplication factor version of 106% 1.06.

Multiply the cost of the ball by your multiplication factor:

30 x 1.06 = 31.8

Money is written to two decimal places, making your answer $31.80

Answer:

A. is incorrect. He has to divide 76 by 19, instead of subtracting 19 to 76.

B. This equation has one solution. v=4

Step-by-step explanation:

Hi, Martin’s answer is incorrect.

A. He has to divide 76 by 19, instead of subtract 19 to 76.

The correct steps are:

19v = 76

Since 19 is multiplying the variable, to eliminate it we have to divide by 19.

v = 76/19

v = 4

B. This equation has one solution. It’s v=4

Can someone help me, I don’t get this

dmitriy555 [2]

I'll break it down for you. Here are the main points:

-has 2 large servings

-made from 9 pints

-x represents how many pints

-y represents how many servings

Now that we know this we can find what each serving comes out to be for example:

$\frac{9}{2\\}$ =4.5 or 4 $\frac{1}{2}$

So for each serving it will come out to be 4.5 pints.

Now that we know this we can figure out the slope to find what the equation which is for example the slope for this equation would be rise over run for example:

$\frac{rise}{run}$ = $\frac{1}{4.5}$ = $\frac{2}{9}$ when simplified.

So our equation would be (also the answer) y= $\frac{2}{9}$ x

Hope this helps my dude ^^ If you have more questions go ahead and ask.
