1 answer:

Answer:

$1040

Step-by-step explanation:

Firstly, we must lay down all the details given..

●The price increased by 30% that means that the original price which was 100% is now 130%

●The present price which is the original price for now is 100%.

One way we can show these details is by mathematical term, proportional method.

So,

100%= $800

1%=800÷100

130%= 800÷100×130

= $1040

Hope it helps!

A 6.3<br> B 7.5<br> C 6.7<br> D 6.5
Arlecino [84]
So in this case use sine to figure this out.

To convert 48 to the ratio, you gotta use a calculator unless you've memorized everything. do sin(48), which equals about 0.74.

Since Sin is opposite / hypotenuse, 5/h must equal 0.74

So do 5 / 0.74 to get about 6.76 as your answer.
