F(h)= 20 +25h

next plug in the hours but first you need to take the minutes and transfer them to hours

120 minutes = 2 hours

so you plug in 20 + 25(2)

that equals 70

therefor your answers are

f(h)= 20 +25h
and
$70

Martin is paid an hourly rate of d dollars per hour for the first 40 hours he works per week. He is paid one-and-a-half times hi

Nat2105 [25]

Answer:

40d + 10(1.5d) = 770 can be used to determine Martin's hourly pay.

Step-by-step explanation:

Given that:

Hourly rate = d

Earning to first 40 hours = 40d

Earning of more than 40 hours = 1.5d

Amount paid per week = $770

Hours worked = 50 hours

first 40 hours + 10 hours = total earned

40d + 10(1.5d) = 770

Hence,

40d + 10(1.5d) = 770 can be used to determine Martin's hourly pay.

A waitress sold 12 ribeye steak dinners and 39 grilled salmon totaling $575.53 on a particular day. Another day she sold 25 ribe

Talja [164]

Answer:

cost of ribeye steak dinners = $10.36

cost of grilled salmon= $11.581

Step-by-step explanation:

Let the cost of one steak dinners be x

Let the cost of one grilled salmon be y

One a particular day the waitress sells 12 ribeye steak dinners and 39 grilled salmon for a total is $575.53 which can be written in equation as

12(x)+39(y)= $575.53-------------------------------------(1)

On another day she sells 25 ribeye steak dinners and 13 grilled salmon dinners totals to $582.43.This can be represented as

25(x)+ 13(y)= $582.43-------------------------------------(2)

solving the equation (1) and (2)

eq(1) x 1 $12x+39y= 575.53$

eq(2) x 3 $125x+ 39y= 1747.29$ -------------------------(3)

Subtracting these equation we get,

$113x=1171.76$

$x=\frac{1171.76}{113}$

x= 10.36

Now substituting this in equation (1)

$12(10.36)+39(y)= $575.53$

$123.84+39y=575.53$

$39y=575.53 - 123.84$

$y=\frac{451.69}{39}$

y=11.581

Kai used fabric measuring 5 yards in length to make each costume for a school play. The relationship between the number of costu

Yuki888 [10]

The best interpretation of 2 in the given context is that; 2 represents the total length of fabric in yards purchased when no costumes were made.

<h3>Slope Intercept Form</h3>

We are given the relationship between the number of costumes that Kai made, x, and the total length of fabric that he purchased y, in yards as; y - 5x = 2

Where;

x is number of costumes made
y is total length of fabrics purchased.

Now, the general slope intercept form of an equation is given by; y = mx + c

Where c is the y-intercept which is the point where x is zero.

Thus, our equation can be rewritten as;

y = 5x + 2

Comparing with y = mx + c, we can say that c = 2

This means that at x = 0, y = 2.

In conclusion, the value 2 represents the length of yards purchased when no costumes were made.
