The cost to mail a package is $7 for the first 2 pounds and 30 cents for each additional ounce. Which of the following functions

TiliK225 [7]

The cost to mail a 2-lb package is $7.
The cost to mail a 2-lb, 1 oz package is $7+$0.30(1).
That to mail a 2-lb, 2 oz package is $7+$0.30(2) = $7.60.

Following this pattern, the general formula is f(x) = $7 + $0.30x, where x represents the number of ounces OVER 2 lb.

if a rectangle is twice as long as it wide and has a perimeter of 48 inches, what is the area of the rectangle

luda_lava [24]

Answer: 128 $in^{2}$

Step-by-step explanation:

Let the width be W then the length will be 2W since it is twice as long as it width.

The formula for calculating the perimeter of a rectangle is given by :

P = 2 ( L + W )

48 = 2 ( W + 2W )

48 = 2(3W)

48 = 6W

Divide through by 6

Therefore:

W = 48/6

W = 8 inches

This means that the Length is 2 x 8 = 16 inches

Area = Length x breadth

Area = 16 x 8

Area = 128 $in^{2}$

$\frac{10}{9} = \frac{9}{y} \ \ \ \ \ \ \ \ \ \ \ \ |\hbox{cross multiply} \\
10 \times y=9 \times 9 \\
10y=81 \ \ \ \ \ \ \ \ \ \ |\div 10 \\
y=\frac{81}{10} \\ \\
\boxed{y=\frac{81}{10}}$
