Given data

ratio= 10: 7: 5

Total ratio= 10+7+5= 22

Lisa= $20

Her proportion of the ratio = 7

Applying the part to all method

Let the total amount shared be x

7/22= 20/x

cross multiply

7x= 22*20

7x= 440

divide both sides by 7

x= 440/7

x= 62.85

Answer:

See attachment for triangle

Step-by-step explanation:

Given

Shape: Equilateral triangle

$Perimeter = 10cm$

Required

Draw the triangle

First, we determine the side lengths.

The perimeter of an equilateral triangle is:

$Perimeter = 3 * Length$

So, we have:

$10= 3 * Length$

Solve for Length

$Length = \frac{10}{3}$

$Length = 3.33$

Hey there!

$20 \dfrac{1}{2} - 5 \dfrac{5}{12} - 3 \dfrac{1}{3} + 2 \times 10 \dfrac{1}{2} \\ = \dfrac{41}{2} - \dfrac{65}{12} - \dfrac{10}{3} + 21 \\ = \dfrac{246}{12} - \dfrac{65}{12} - \dfrac{40}{12} + 21 \\ = \dfrac{141}{12} + 21 \\ = 32 \dfrac{3}{4}$

Answer : 32 3/4 feet or in decimal form, 32.75 feet.

The shortest side of a triangle is 12cm and the area of the triangle is 8 square cm. A similar triangle has an area of 18 square

sdas [7]

Answer:

27cm

Step-by-step explanation:

Given the following :

Triangle A:

Shortest side = 12cm

Area of triangle = 8cm^2

Triangle B:

shortest side =?

AREA of triangle = 18cm^2

If triangle A and B are similar :.

Area A / Area B = Length A / length B

8cm^2 / 18 = 12 / length B

Cross multiply :

8cm * Length B = 18 × 12

Length B = 216 / 8

Length B = 27

Therefore, the shortest of the other triangle IS 27cm
