A rectangle has an area of 96 sq ft if the width of the yard is 4 ft less than the length, what is the perimeter in ft of the ya

Veronika [31]

The area of a rectangle is obtained through the equation,

A = L x W

The width of the yard is 4 ft less than the length and may be expressed as L - 4. Length may be solved through the following steps,

A = (L)(L-4) ; 96 = L(L - 4) ; L = 12 ft

The length and width are 12 ft and 8 ft, respectively. Perimeter may be solved through the equation,

P = 2 x (L + W)

Substituting the values of L and W

P = 2 x ( 12 ft + 8 ft) = 40 ft

Therefore, the perimeter of the yard is 40 ft.

A photocopy machine can print 735 copies in 7 minutes.what is the rate at which the machine prints the copies per minute

11111nata11111 [884]

The copy machine makes 105 copies per minutes.

Step-by-step explanation:

Given,

Copies printed by photocopy machine = 735

Time taken by machine = 7 minutes

To find the unit rate in terms of minutes, we will divide the copies printed by machine by the time taken.

Copies printed in one minute = $\frac{735}{7}$

Copies printed in one minute = 105 copies

The copy machine makes 105 copies per minutes.

Answer:

t = 130s

Step-by-step explanation:

$s = 3.9 * 10^{7} km$

$v = 3 * 10^{5} km/s$

$t = ?$

$t = \frac{s}{v}$

$t = \frac{3.9 * 10^{7} km}{3 * 10^{5}km/s }$

$t = 130 s$
