Step-by-step explanation:

$\frac{5}{1 - \sqrt{7} } \\ multiply \: both \: by \: (1 + \sqrt{7) } \\ \frac{5(1 + \sqrt{7)} }{(1 - \sqrt{7})(1 + \sqrt{7)} } \\ = \frac{5(1 + \sqrt{7)}}{1 - { \sqrt{7} }^{2} } \\ = \frac{5(1 + \sqrt{7)} }{1 - 7} \\ = \frac{5(1 + \sqrt{7)} }{ - 6} \\ = \frac { - 5}{ \: 6} \frac{(1 + \sqrt{7}) }{}$

G=h(t) + p(c) is an equation that represents the gross pay of a server: Gross pay = hourly wage (time worked) + percent tip (cos

rusak2 [61]

Answer:

$105.5 for 16 hours at $6.59 per hour

Step-by-step explanation:

form the equation given, G=h(t) + p(c)

where G=Gross pay,

h= hourly wage

t=time worked

p=percent tip

c=cost of customer meals

we determine the gross pay by first determining the independent variables

h=$4.25, t=16 hours,

$p=15%of c\\p=\frac{15}{100}*250 \\p=37.5$

if we substitute values, we arrive at

$G=h(t)+p(c)\\G=4.25(16)+37.5\G=68+37.5\\G=105.5$

to determine the per hour gross pay we have

105.5/16

hourly gross pay,G=$6.59

How to do you find the radius of a square with a circle inscribed into it?

Shkiper50 [21]

<span>When used in reference to a square, the radius is the distance from the center of the square to any of the four vertices, or where two sides intersect. Because a square has four right angles, you can find the diameter of the square using the Pythagorean Theorem. Multiply the side length of the square by itself.

AKS 18/19 A travel agent is arranging a private cruise. The agent can arrange for, at most, 40 people to go on the trip. The tri

zlopas [31]

Answer:

M + W <= 40

M >= 12

M >= 15

Total profit = $26 * M + $14 * W

Step-by-step explanation:

Let the number of men be denoted by M

number of women be denoted by W

Maximum no of people that can go one trip = 40

Therefore representing it mathematically we have

M + W <= 40 -------------- CONSTRAINT 1

Minimum number of men needed on trip = 12

Therefore representing it mathematically we have

M >= 12 CONSTRAINT 2

Minimum number of women needed on trip = 15

Therefore representing it mathematically we have

M >= 15 CONSTRAINT 3

profit on 1 man = $26

profit on M men = $26 * M

profit on 1 woman = $14

profit on M men = $14 * W

Total profit combining for men and women =

$26 * M + $14 * W -------------CONSTRAINT 4

___________________________________________

writing together all the constraint

M + W <= 40

M >= 12

M >= 15

Total profit = $26 * M + $14 * W
