Easton and Eli go to the movie theater and purchase refreshments for their friends.

Hatshy [7]

Answer:

Price of one bag of popcorn: $9.5

Price of one drink: $5.5

Step-by-step explanation:

Let be "b" the price in dollars of a bag of popcorn and "d" the price in dollars of a drink.

You know that the total amount of money Easton spends on on 9 bags of popcorn and 6 drinks, is $118.50. Then,this can be represented with the following equation:

$9b+6d=118.50$

Knowing that Eli spends $83.50 on 3 bags of popcorn and 10 drinks, you can write the second equation:

$3b+10d=83.50$

Then, the System of equations is:

$\left \{ {{9b+6d=118.50} \atop {3b+10d=83.50}} \right.$

You can use the Elimination methot to solve it:

1. Multiply the second equation by -3.

2. Add both equations.

3. Solve for "d"

Then, you get:

$\left \{ {{9b+6d=118.50} \atop {-9b-30d=-250.5}} \right\\............................\\-24d=-132\\\\d=5.5$

4. You can subsitute "d" into the second equation and solve for "b":

$3b+10(5.5)=83.50\\\\3b=83.50-55\\\\b=9.5$

Which ordered pair could not be the coordinates for a clockwise rotation of the point W(-3, 4)?

Eduardwww [97]

Step-by-step explanation:

Look at the picture.

Any pair of choice can be the coordinates of the rotation of the point

W (-3, 4) clockwise.

All points have the same distance from the beginning.

The formula of a distance between the origin and a point (x, y):

$d=\sqrt{x^2+y^2}$

W(-3, 4)

$d=\sqrt{(-3)^2+4^2}=\sqrt{9+16}=\sqrt{25}=5$

(3, -4)

$d=\sqrt{3^2+(-4)^2}=\sqrt{9+16}=\sqrt{25}=5$

(4, 3)

$d=\sqrt{4^2+3^2}=\sqrt{9+16}=\sqrt{25}=5$

(-4, -3)

$d=\sqrt{(-4)^2+(-3)^2}=\sqrt{9+16}=\sqrt{25}=5$

(-4, 3)

$d=\sqrt{(-4)^2+3^2}=\sqrt{9+16}=\sqrt{25}=5$

Biology application. The approximate number of calories C that an animal needs each day is given by

Reika [66]

Answer:

C = 288 kg

Step-by-step explanation:

Given:

C = 72m^2/4

where,

C = approximate number of calories

m = animal mass in kilograms.

Find C when m = 16

C = 72m^2/4

= 72 * (16)^2/4

= 72 * (16)^1/2

= 72 * √16

= 72 * 4

= 288

C = 288 kg
