Volume is length times width times height so you would take 10656/(24*18.5)=24 inches

Use the formula V = Bh and plug in the given numbers. So the formula would be 10,656 = l*24*18 1/2 and you would get length = 24

A college parking lot is 140 ft long and 90 ft wide. The college wants to increase the area of the lot by 29% by adding strips o
Novay_Z [31]
The initial dimenssions of the park lot are:

length: 140 ft
width: 90 ft

initial area: 140 * 90 = 12,600 ft^2

Area increased 29% = 12,600 * 1.29 = 16,254 ft^2

width of the strips: x

New length: 140 + x

New width: 90 + x

New area: (140+x)(90+x) = 16,254

Solution of the equation:

12600 + 230x + x^2 = 16254

=> x^2 + 230x - 3654 = 0

Use the quadratic formula.

x = {-230 +/- √[ 230^2 - 4*1*(-3654) ]} / 2 =

x = 14.92

The other solution is negative so it is discarded.

Answer: 15 ft

Is y = 3/2x +5/4 and -2x+8y=-25 a solution
nekit [7.7K]

Answer: x=-35/10

              y=-4

Step-by-step explanation:

y = 3/2x +5/4

-2x+8y=-25

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

replace y in second equation with: y = 3/2x +5/4

-2x+8(3/2x+5/4)= -25

-2x+12x+10= -25

10x=-35

x=-35/10

x=-3.5

7+8y= -25

8y=-32

y=-4
