some numbers added to -11 is 37.divide this number by -12.then multiply by -8.what is the final number?

1 answer:

6 0

Since some number added to -11 is 37, we must do 37- (-11), which is 48. Then we check our work and find that 48+-11 is indeed 37. Now we divide 48 by -12, which is -4, multiply by -8 and get a final answer of 32.

The sides of a triangle are in the ratio 3:4:5. What is the length of each side if the perimeter of the

Brut [27]

Answer:

A. 22.5 cm, 30 cm, and 37.5 cm

Step-by-step explanation:

If three sides of a triangle are in the ratio 3:4:5, then the lengths of the sides are 3x cm, 4x cm and 5x cm.

The preimeter of the triangle is the sum of the lengths of all sides, thus

$3x+4x+5x=90\\ \\12x=90\\ \\x=\dfrac{90}{12}=\dfrac{30}{4}=7.5\ cm$

So, the lengths of the triangle's sides are

$3x=3\cdot 7.5=22.5\ cm\\ \\4x=4\cdot 7.5=30\ cm\\ \\5x=5\cdot 7.5=37.5\ cm$

Georgia [21]

Answer:

$74.40 cents

Step-by-step explanation:

Given the following question:

20% of 62

In order to find the answer, we use the formula to calculate percentage, then we add that answer onto the bill.

$\frac{p\times n}{100}$
$\frac{20\times62}{100} =20\times62=1240\div100=12.4$
$=12.4$

<u>Now add:</u>
$62+12.40=74.40$
$=74.40$

Which means in total after a 20% tip the Smiley family paid "$74.40 cents" for their meal.

Hope this helps.
