Answer:

300 in³

Step-by-step explanation:

The volume is:

V = Bh, where B- area of base, h - height

Find the area of base, which is the trapezoid:

B = 1/2*(5 + 7.5)*6 = 37.5 in²

Find the volume:

V = 37.5*8 = 300 in³

An old movie theater has seats on a main floor and in a balcony. The main floor has 26 rows of 29 seats in each row. The balcony

Archy [21]

The main floor has 26 rows of 29 seats each, that is 26*29 = 754 seats
And in the balcony there is 8 rolls of 23 seats, that is 8*23 = 184 seats
So the difference is 754 - 184 = 570
Then the main floor has 570 seat more than the balcony

An acre measures 4840 square yards. In a city, a lot on which a single-

belka [17]

The lot is 9.2% of the an acre.

Given:

Area of an acre = 4840 sq. yards

Area of lot = 40 by 100 ft = $40 ]\times 100 = 4,000 $ ft^{2}$

Convert the area of the lot to feet ( $9 ft^{2} = yd^{2}$ ):

Therefore:

Area of lot = $\frac{4,000}{9} = 444.4 $ yd^{2}$

Percentage occupied by the lot = area of lot / area of acre x 100

$= \frac{444.4}{4840} \times 100\\\= 9.2$

The lot therefore is 9.2% of the an acre.

7(5x + 9) = 12 - (x +9)

den301095 [7]

Answer:

$\frac{-5}{3}$ is the answer

Step-by-step explanation:

7(5x+9)=12+−1(x+9)(Distribute the Negative Sign)

7(5x+9)=12+−x+−9

(7)(5x)+(7)(9)=12+−x+−9(Distribute)

35x+63=12+−x+−9

35x+63=(−x)+(12+−9)(Combine Like Terms)

35x+63=−x+3

Add x to both sides.

35x+63+x=−x+3+x

36x+63=3

subtract 63 from both sides.

36x+63−63=3−63

36x=−60

Divide both sides by 36.

$\frac{36x}{36} =\frac{-60}{36}\\$

-5/3 is the answer.

ik this doesnt make any sense but hope this helps
