Two triangles are similar . The sides of the smaller triangle have lengths of 8,12, and 16 centimeters. The perimeter of the larger triangle is 54 centimeters. Find the length of the shortest side of the triangle.

Answers

Answer:

The shortest side of the larger triangle is 12 cm

Step-by-step explanation:

we know that

If two triangles are similar, then the ratio of its perimeters is equal to the scale factor

step 1

Find the perimeter of the smaller triangle

$P=8+12+16=36\ cm$

step 2

Find the scale factor

Divide the perimeter of the larger triangle by the perimeter of the smaller triangle

$(54)/(36)= 1.5$

step 3

Find the length of the shortest side of the larger triangle

Multiply the shortest side of the smaller triangle by the scale factor

$(8)1.5=12\ cm$

shari has 1 1/2 gallons of orange juice. She wants to serve the orange juice equally among her 12 friends. How many ounces of juice will each friend receive

Answers

I got the answer 8 ounces. First you convert the gallons into ounces. There are 64 ounces in a gallon. But then one half of a gallon equals 32 ounces. Add 32+64=96. Then divide the 96 by the 12 friends. You would get 8. And so that is the answer. I hope you found this helpful!

Solve picture question. Mathematics.

Answers

Cross multiplication!
$(7)/(8)$ = $(x)/(24)$
7 × 24 = 8x
168 = 8x

Divide both sides by 8 to isolate x

$(168)/(8)$ = $(8x)/(8)$
8 and 8 cancels out

21 = x

8*?=24? 8*3=24. So multiply 7 also by 3, and the answer is 21 :)
