Maya is making dream catchers with her family. Each dream catcher takes 1.53 feet of string. She has 6 people in her family. How much string does Maya need total?

1.53*6=9.18

You know where to put the decimal because you count how many places in the decimal is for the two numbers being multiplied (the only decimal in the two numbers being multiplied is in the number 1.53 and that’s is two places in) and then go that many places in on the product (918 two places in from then right would be 9.18)

Luis wants to buy a skateboard that usually sells for $79.91. All merchandise is discounted by %12. What is the total cost of th

quester [9]

Answer:

Luis' skateboard will cost $76.32.

Step-by-step explanation:

Divide 79.91 by 100, this is what one percent is worth, .7991.

Multiply this by 12, giving you 12 percent, 9.59 (rounded to the nearest 10th).

Now subtract 9.59 from 79.91, 70.32. That is the price BEFORE tax.

Than divide 70.32 by 100, .7032.

Multiply this by 8.25, 5.80, this is tax.

Now add the price before tax, 70.32, to the tax, 5.80.

This creates 76.12. This means that the total price of the skateboard is $76.32.

1.10=1+2b
subtract 1 from both sides
.10=2b
divide by 2 on both sides
ball=5 cents

(-4)(-4) use an exponent to rewrite the expression

DiKsa [7]

For this case we have the following expression:
<span> $(-4)(-4) 
$
By properties of exponents we have:
Same basis, the exponents are added.
We have then:
$(-4)^{1+1}$
Then, rewriting the exponent we have:
$(-4)^{2}$
Therefore, an exponent to rewrite the expression is:
2
Answer:
$(-4)^{2}$
an exponent to rewrite the expression is 2.</span>
