<h2>Answer:</h2>

             80% more than 20 is:

                             36

<h2>Step-by-step explanation:</h2>

80% more than twenty means that there is an addition of 80% of 20 to the amount 20.

i.e. we have to calculate 80% of 20 and add it to 20 to get the total amount.

Now, 80% of 20 is:

=\dfrac{80}{100}\times 20\\\\\\=\dfrac{1600}{100}\\\\\\=16

Now, 80% more than 20 is equal to:

             20+16=36

    Hence, the quantity is:

               36

Please help !!!!!!!!!
atroni [7]

Answer:

Katherine invested $12,000

Step-by-step explanation:

Use formula

I=P\cdot r\cdot t,

where

I = interest,

P = principal,

r = rate (as decimal),

t = time (in years).

In your case,

t = 1 year,

r = 0.06 (or 6%)

P + I =$12,720, thus

12,720-P=P\cdot 0.06\cdot 1\\ \\12,720-P=0.06P\\ \\12,720=P+0.06P\\ \\1.06P=12,720\\ \\P=\dfrac{12,720}{1.06}\\ \\P=\$12,000\\ \\I=\$12,720-\$12,000=\$720

Determine the possible side lengths of the third side of a triangle with known side lengths 3 and 6. answers: –3 &lt; c &lt; –9
vovangra [49]

Answer:

3 < c < 9

Step-by-step explanation:

The length of a side of a triangle cannot be negative. This eliminates the first and last options.

The addition of two sides of a triangle must be greater than the third side. In this case:

3 + 6 = 9 > c

So, the second option is correct. The third option is not correct, because, for example, c = 8 is possible

Ninety percent of a town’s population owns cars. If the number of cars owned is 4761, what is the population of the town?
Nuetrik [128]

We can write an equation of this, with p representing the unknown population. We know that 90% of the population owns cars:

90% * p

We also know that 4761 people own cars, which is the same as the above expression, so we write:

90% * p = 4761.

From there, you just divide both sides by 90%, or 0.9

p = 4761/0.9 = 5290

The population is 5290 people.
