A forest covers 33,000 acres. A survey finds that 0.8% of a forest is old-growth-tree. How many acres of old-growth-trees are there?

Answers

Answer:

264 acres

Step-by-step explanation:

Since 33,000 acres is 100%, 330 acres is 1% because 33000 acres divided by 100 is 330 acres. Then if 330 acres is 1%, 33 acres is 0.1% because 330 acres divided by 10 is 33 acres. 1 divided by 10 is 0.1.

Next 33 acres times 8 because 0.8% is eight times bigger than 0.01%. This equals to 264 acres.

My coordinate was 3, 6 and applied the -7 -6 rule and got -4,0.

Then I used the rule that they have to translate it back which was -6 -7 and there’s no way it can be translated back to 3, 6

So the answer is no the rule can’t be used to translate it back

$7.50 meal; 6.5% tax _____

Answers

Answer:

14.0

Step-by-step explanation:

$7.50 meal + your 6.5$ tax.

We add those and it will equal 14.00

We need to add 100% to it so now it's: 106.5%

Now we need to change it to a decimal and we do that by moving the decimal two spaces to the left.

106.5 = 1.065

We now multiply 1.065 and $7.50

7.50 × 1.065 = 7.9875

We need to round it so now it's $7.99
