The price of a cup of coffee was 2:40 yesterday today it Rose 265 find the percentage increase

1 answer:

6 0

N.B. I believe your question is saying that the price of a cup of coffee was $2.40 yesterday, and it rose to $2.65 today. Therefore, I will solve with these prices.

The percent increase is 10.41666666% (The 6 is repeating.).

First, you find the difference, or increase, between the two prices.

New price - Old price = Increase

$2.65 - $2.40 = $0.25

The difference between the two prices is $0.25. To find the percent increase, you want to divide the original price ($2.40) from the increase ($0.25) and multiply by 100.

Increase ÷ Original Price × 100 = % increase

0.25 ÷ 2.40 × 100 = 10.41666666%

The percent increase is 10.41666666% (The 6 is repeating.).

What is the length of the hypotenuse of a right triangle with sides that measure 7 cm and 24 cm?

Paul [167]

The length of the hypotenuse of a right triangle with sides that measure 7 cm and 24 cm is 25 cm

<u>Solution:</u>

Given a right angled triangle,

The sides measure 7 cm and 24 cm

We have to find the length of hypotenuse

For a right angled triangle, by Pythagorean theorem, which states that the square of the length of the hypotenuse is equal to the sum of squares of the lengths of other two sides of the right-angled triangle.

From above definition we get,

$c^2 = a^2 + b^2$

Where, "c" is the length of hypotenuse

"a" is the length of one side of triangle

"b" is the length of other side of triangle

Here, a = 7 and b = 24 and c = ?

$c^2 = 7^2 + 24^2\\\\c^2 = 49 + 576 = 625$

Taking square root on both sides,

$c = \sqrt{625}\\\\c = 25$

Hence the length of hypotenuse is 25 cm

Answer: 11.4 feet of the ground

Step-by-step explanation:

You would use sin to get the answer. So it'd be sin(72) = x/12

Once you get the sin you would multiply it by the 12 to get the x by itself and that's your answer.

It would be sin because the question is asking for that side, and it's across the 72, making it the opposite side, the side that is across from the 90 degrees is always the hypotenuse and you have a number for that side and sin uses the opposite and hypotenuse
