Answer:

799.99999 or 800 miles.

Step-by-step explanation:

You first need to find the conversion rate, so you divide 500 by the number representing it on the map, that being 1.7 feet. Once you've done this, you will get a conversion rate of 294. Now that you have the conversion rate, you multiply your second number, 2.72. This will give you your answer of 799.68 miles, which can be rounded up to 800 miles.

Answer:

Option A: 4 units is the correct answer.

Step-by-step explanation:

Given that:

Layana's house is located at ( $2\frac{2}{3}, 7\frac{1}{3}$ )

Store is located at ( $-1\frac{1}{3},7\frac{1}3}$ )

We can find distance between two points by using distance formula.

S = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2$

The points can also be written as;

House (8/3, 22/3)

Store (-4/3, 22/3)

Putting values in the formula.

S = $\sqrt{\frac{8}{3}-(-\frac{4}{3}))^2+(\frac{22}{3}-\frac{22}{3})^2$

S = $\sqrt(\frac{8}{3}+\frac{4}{3}+0$

S = $\sqrt{(\frac{8+4}{3})^2$

S = $\sqrt{(\frac{12}{4})^2$

S = $\sqrt{(4)^2$

S = 4 units

Hence,

Option A: 4 units is the correct answer.

A photo lab usually charges 1.45 per print to make a color print from a color transparency. During a special promotion, the char

Answer:

$\large \boxed{\math{\$24.05; < 9}}$

Step-by-step explanation:

Let n = the number of prints

and C = the total cost.

At the regular price, the formula is

C = 1.45n

During the promotion, you must pay for the first nine prints: 9 × 1.45 = 13.05.

For anything over nine prints (n - 9), you must pay $13.05 plus the promotional cost of $1.10 for each print. The promotional formula is

C = 13.05 + 1.10(n - 9) {n > 9}

1. Calculate the cost of 19 prints

$\begin{array}{rcl}C & = & 13.05 + 1.10(19 - 9)\\ & = & 13.05 + 1.10 \times 10\\ & = & 13.05 + 11.00\\ & = &24.05\\\end{array}\\\text{The cost of 19 prints is $\large \boxed{\mathbf{\$24.05}}$}$

2. What number of the prints is a waste of money?

During the promotion, buying fewer than nine prints would be a waste of money, because you would not be taking advantage of the promotional savings.
