Answer:

12. 11/18-1/6=4/9

13. 2/7+2/5=24/35

14. 3/4-3/10=9/20

Step-by-step explanation:

12. 11/18-1/6

11/18-1/6=11/18-(1/6)*(3/3)

11/18-1/6=11/18-(1*3)/(6*3)

11/18-1/6=11/18-3/18

11/18-1/6=(11-3)/18

11/18-1/6=8/18

Dividing the numerator and denominator of the fraction on the right side of the equation by 2:

11/18-1/6=(8/2)/(18/2)

11/18-1/6=4/9

13. 2/7+2/5

2/7+2/5=(2/7)*(5/5)+(2/5)*(7/7)

2/7+2/5=(2*5)/(7*5)+(2*7)/(5*7)

2/7+2/5=10/35+14/35

2/7+2/5=(10+14)/35

2/7+2/5=24/35

14. 3/4-3/10

3/4-3/10=(3/4)*(5/5)-(3/10)*(2/2)

3/4-3/10=(3*5)/(4*5)-(3*2)/(10*2)

3/4-3/10=15/20-6/20

3/4-3/10=(15-6)/20

3/4-3/10=9/20

A floodlight red light at ground level Shines on a 4 ft tall Bush that is 6 ft away the bush cast a shadow on a building that is

Lerok [7]

Set up the proportion as follows: $\frac{bush (height)}{bush (length)} = \frac{building (height)}{building (length)}$ , then cross multiply to solve.

$\frac{4}{6} = \frac{x}{24}$

4(24) = 6(x)

4(4) = x <em>(divided both sides by 6)</em>

16 = x

Answer: 16 ft

A box with a square base and no top is to be built with a volume of 4000 in3. find the dimensions of the box that requires the l

vekshin1

Let the length of the square base be x inches .

And the height of the box be y inch .

Volume = x*x*y

4000 = x *x *y

$y = \frac{4000}{x^2}$

S = x*x + 2xy + 2 x y

$S = x^2 + 4 xy$

$S = x^2+ 4x* \frac{4000}{x^2}$

$S = x^2 + \frac{16000}{x}$

$S ' = 2x - \frac{16000}{x^2}$

S ' =0

$2x - \frac{16000}{x^2}=0$

$2x^3 - 16000 = 0$

$x^3 = 8000$

x = 20

$y = \frac{4000}{20^2} = \frac{4000}{400} = 10$
