Answer:

The combined average length of five male elephants is 3750cm

Step-by-step explanation:

1 elephant = 7.5m

5 elephants=?

We cross multiply.

5 * 7.5= 37.5m

So the average combined length of 5 male elephants is 37.5m

So we convert 37.5m to centimetres

Recall, 100cm = 1m

With this in mind, we convert 37.5m to cm by multiplying by 100

So, 37.5 x 100= 3750cm.

5. Last year, Mr. Petersen's rectangular garden had a width of 5 meters and an area of 20 square meters.
11111nata11111 [884]

Answer:

Last Year Length = 4 meters

This Year Length = 12 meters

This Year Width = 10 meters

Step-by-step explanation:

We know, area of the rectangle is given by the formula:

Area = Length * Width

Given width = 5

Area = 20

We solve for Length:

Area = Length * Width

20 = Length * 5

Length = 20/5 = 4

Last Year Length = 4 meters

Now, this year, the length would be 3 times as long, so new length would be:

This Year Length = 4 * 3 = 12 meters

This year, the width would be two times previous year, so width would be:

This Year Width = 5 * 2 = 10 meters

How do you find the area of a composite figure?
Orlov [11]

Answer:

See below.

Step-by-step explanation:

Top prism:

To find the volume of the top prism, multiply the area of the base by the height. This is 1/2 times width times height times length.

V =1/2 l*w*h =1/2* 3*2.8*8 = 33.6

To find the surface area of a prism, find the area of the triangular base and the area of each rectangular side.

Area of the base is A = 1/2 * b*h = 1/2 * 3 * 8 = 12. Since there are 2 bases, the area is 24.

Area of the rectangular side is A = b*h = 2.8*5 = 14. Since there are two, the area is 2*14 = 42.

The surface area of the prism is 24 + 28 = 52.

Bottom prism:

To find the volume of the bottom prism, multiply the width times the height times the length.

V = l*w*h = 8*2.8*4.8 = 107.52

To find the surface area of the bottom prism, find the area of the base and each side of the house.

A = 8*2.8 = 22.4

A = 8*4.8 = 38.4 which occurs twice so it has a total area of 76.8

A = 2.8*4.8 = 13.44 which occurs twice so it has an area of 26.88.

The total volume is 33.6 + 107.52 = 141.12

The total surface area is 52 + 22.4 + 76.8 + 26.88 = 178.08

Martin charges $15 for every 5 bags of leaves he rakes. Last weekend, he raked 27 bags of leaves. How much money did he earn?
Burka [1]
Set up a proportion and then cross multiply to solve. OR. 15/5 = $3 per bag is the unit rate per 1 bag.
Multiply 27*3=$81
