Answer 1

multiply it using a calculator

Answer 2

Answer:

144 ft^2

Step-by-step explanation:

Here we have a trapezoid with a triangle inside.

The legs of the trapezoid are 18 ft and 8 ft, and so the average length of the trapezoid is (18 + 8)/2 ft, o 13 ft. The total area of the trapezoid is thus:

A = (13 ft)(16 ft) = 208 ft^2

Now we must find the area of the white triangle and subtract it from the area of the trapezoid already found. The area formula for a triangle i

A = (1/2)(base)(height), which in this case is A = (1/2)(8 ft)(16 ft), or

A = 64 ft^2.

Subtracting the area of the triangle from that of the trapezoid yields

Area of figure = 144 ft^2

Answer:

Part 2) 5 hr

Part 3) $80 and $160

Step-by-step explanation:

Part 2) Equate the two pay equations: 20H = 10H + 50

Subtract 10H from both sides: 10H = 50

Then H = 5.

After 5 hours, each would have earned the same amount.

Part 3) In an 8-hour day, one guy would earn ($20/hr)(8 hr) = $160, and the other guy would earn ($10/hr)(8 hr) = $80.

30 books on the shelf are Fiction.

Step-by-step explanation:

Hey!

There are 50 books on a shelf.

1/5 of the books are Science Fiction.3/10 are Non-Fiction.The Rest are Fiction.

how many books on the shelf are Fiction?

==================================================================

MAKE AN EQUATION!

We know that there are three Categories: Fiction, Science Fiction, and Non Fiction.

Total- 50

⇒ 50 =

1/5 of 50 are SF

⇒ 50 = (1/5)(50)

3/10 of 50 are NF

⇒ 50 = (1/5)(50) + (3/10)(50) + x

--------------------------------------------------------------------------------------------------------------

SOLVE THE EQUATION!

(1/5)(50) + (3/10)(50) + x = 50

To Isolate X-

-Multiply and remove the parentheses..

⇒ 50/10 + 150/10 + x = 50

-Simplify.

⇒ 5 + 15 + x = 50

-Add Like Terms

⇒ 20 + x = 50

-Subtract 20 from both sides.

⇒ 20 + x - 20 = 50 - 20

-Simplify Right Hand Side.

⇒ x = 30

--------------------------------------------------------------------------------------------------------------

So, 30 books on the shelf are Fiction.

Answer:

triangle side = 0.54

so both triangle sides = 1.08

and then the sides (1.5 * 3.5) * 2 = 10.5

the last side = 0.9 * 3.5 = 3.15

so add it all 3.15 + 10.5 + 1.08

total area = 14.73 m^2

Il pretty sure it’s 15.73 m^2
