Amount of material =area
area of triangle=1/2 times base tiems ehighte

base=2 and 1/4
height=8 and 1/2
convert all to imporpoert
2 and 1/4=2+1/4=8/4+1/4=9/4
8 and 1/2=8+1/2=16/2+1/2=17/2
so we have
area=1/2 times 9/4 times 17/2
area=(1 times 9 times 17)/(2 times 4 times 2)
area=153/16
area=9 and 9/16

answer is 9 and 9/16 square units of material

The equation of the given line is....?
liq [111]

Answer:y=3x+3

Step-by-step explanation: the y-intercept is 3, and the slope is 3/1, which is 3. Technically the answer is not enough information, as it is not given how many units one square is.

Someone explain this?
nadya68 [22]

5\sqrt{96}.
I converted it into decimal form with a calculator and got approximately 48.9898

And if you round that, you will get the 49, which fits the inequality of

45<  5\sqrt{96} < 50 since it becomes 45 < 49 < 50 which is true

A bicycle wheel has a diameter 60inches how many rotations would it take to go 600 feet
hichkok12 [17]
First, we want to convert 600 feet to inches:

600 feet (12 inches/ft) = 7200 inches

We know that the diameter is 60 inches, so the circumference is 60π inches or 188.5 inches.
We can divide 7200/188.5 to get about 38.2 rotations.

Triss [41]
For downstairs- 28 x 38= 1064

For upstairs- 26 x 14= 364

All together- 1064 + 364= 1428


So.... 1428 seats in total.

Hope this helped! :)
