A manager needs to order company shirts for each employee. She was quoted the following rates. If she orders 75 shirts and passe
Rainbow [258]

Answer:

The answer is $7.47.

Step-by-step explanation:

calculate how much in total 75 shirts cost:

- first 19 (less than 20) cost $10:       19 * $10 = $190

- the next 30 cost $8:                        30 *  $8 = $240

- the rest (26 = 75 - 19 - 30) cost $5: 26 *  $5 = $130

in total 75 shirts cost $560:

19 * $10 + 30 * $8 + 21 * $5 = $190 + $240 + $130 = $560

Since 75 shirts are ordered, there must be 75 employees, so each employee must pay $7.47:

$565 ÷ 75 = $7.47

Two separate bacteria populations grow each month and are represented by the functions f(x) = 3x and g(x) = 7x + 6. In what mont
harina [27]

Answer:

D. Month 4

Step-by-step explanation:

We are given

Two separate bacteria populations grow each month and are represented by the functions

f(x)=3^x

g(x)=7x+6

now, we can verify each options and check which one holds f(x)>g(x)

option-A:

we can plug x=1

f(1)=3^1=3

g(1)=7\times 1+6=13

so,

f(1)

so, this is FALSE

option-B:

we can plug x=2

f(2)=3^2=9

g(2)=7\times 2+6=20

so,

f(2)

so, this is FALSE

option-C:

we can plug x=3

f(3)=3^3=27

g(3)=7\times 3+6=27

so,

f(3)=g(3)

so, this is FALSE

option-D:

we can plug x=4

f(4)=3^4=81

g(4)=7\times 4+6=34

so,

f(4)>g(4)

so, this is TRUE

Find the slope of the line through the points (3,2) and (4,5).
igomit [66]

Answer:

<h2>The answer is 3</h2>

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

m =  \frac{ y_2 - y _ 1}{x_ 2 - x_ 1}  \\

where

(x1 , y1) and (x2 , y2) are the points

From the question we have

m =  \frac{5 - 2}{4 - 3}  =  \frac{3}{1}  = 3 \\

We have the final answer as

<h3>3</h3>

Hope this helps you
