Answer:

4.82

Step-by-step explanation:

First you do: 4.50 times 7%

To make it easier, you do 7% into a decimal, which is 0.07

Then, you do 4.50 times 0.07, and get 0.315

Lastly, you want to do 4.50 plus 0.315 and get: 4.815

If you want to convert it into the money state, you get $4.82.

The total profit for a company in February was 15% higher than it was in January. The total profit for the two months was $122,9
stepladder [879]

Answer:

The profit for January is $57,200.

Step-by-step explanation:

The total profit for the two months would be the result of adding up the profit in January plus the profit in February:

Total profits=Profit in January+Profit in February

Also, you can say that profits in January can be represented by x and you know that the profit for a company in February was 15% higher than it was in January which can be expressed as: 1.15x. Moreover, you know that the total profit for the two months was $122,980. Now, you can replace the values on the formula:

122,980=x+1.15x

Now, you can solve for x:

122,980=2.15x

x=122,980/2.15

x=57,200

According to this, the answer is that the profit for January is $57,200.

The hypotenuse of a right triangle measures 16 cm and one of its legs measures 9 cm. Find the measure of the other leg. If neces
Vesnalui [34]

\sf\huge\underline{\star Solution:-}

<h3><u>Given that</u>:</h3>
  • Hypotenuse of a right triangle = \sf\blue{16cm.}
  • One side (leg) = \sf\blue{9cm.}

<h3><u>To Find</u>:</h3>
  • Measure of another side(leg).

<h3><u>Solution</u>:-</h3>

\rightarrow As we know that,

\sf{A^2 +B^2 \:=\: C^2}(Pythagoras Theorem)

So, using this formula we can find measure of another side(leg).

\rightarrow\sf{A^2 +B^2 \:=\: C^2}(putting the value of both given side of triangle)

  • Here I am putting the value of hypotenuse in C because it is the longest side of triangle.

\rightarrow \sf{9^2 +B^2 \:=\: 16^2}

\rightarrow \sf{81 +B^2 \:=\: 256}

\rightarrow \sf{B^2 \:=\: 256-81}

\rightarrow \sf{B^2 \:=\: 175}

\rightarrow \sf{B \:=\: \sqrt{175}}

\rightarrow \sf{B\:=\: 13.22(approx)}

Therefore, measure of another side (leg) of the triangle = \sf\purple{ 13.22(approx).}
