20 total oranges

5 are bad.

Subtract the bad from the total to find the number of good ones:

20-5 = 15

There are 15 good oranges out of 20 total.

Divide good by total then multiply by 100 to get the percentage:

15/20 = 0.75

0.75 x 100 = 75%

Answer: 75% are good

Plz answer its easy math.
Serga [27]
<h2>Greetings!</h2>

Answer:

B and E

Step-by-step explanation:

The rules of indicies states:

x^{a} ÷x^{b} = x^{a-b}

So 3^{-8} ÷  3^{-4} =  3^{-8 - - 4} =  3^{-4}

So that means B is one of the correct answers.

To find the other correct value, you can divide the two fractions as stated in the question:

3^{-8} by 3^{-4} = \frac{1}{81}

81 is equivalent to 3⁴

So that means E is also correct.

The area of a patio is 72 square feet. The length of the patio is 1 foot longer than the width. What is the width of the patio?
mote1985 [20]
I know there must be an equation to do this, but there is a simpler way.
Just factor number 72 into two numbers which, when multiplied, equal 72. Two of such numbers are 9 and 8, and you can see that the difference between those two numbers is just 1. So that is the answer to your question - the length of the patio is 9 feet, whereas the width is 8 feet.
