Coffee café mix 90 pounds of coffee that cost six dollars per pound the types of coffee used to make this makes you cost seven d

Troyanec [42]

Answer:

y = 60

Step-by-step explanation:

From the information we get:

x quantity of 4 dollars coffee used in the mix

y quantity of 7 dollars coffee used in the mix

For the quantity of coffee to be sold a 7 $/pound ( 90 pounds)

Then 6*90 = 540 $

Therefore

x + y = 90 and

4*x + 7*y = 540

A two equations system we solve for x and y

y = 90 - x

4*x + 7* ( 90 - x ) = 540

4*x + 630 - 7*x = 540

- 3*x = - 90

x = 30 pounds and

y = 90 - 30

y = 60

We should use 60 pounds of the seven $ coffee

You cut a circular hole 1/4 -inch in diameter in a piece of cardboard. With the cardboard 30 inches from your face, the Moon fit

Stolb23 [73]

Answer:

The Moon's diameter is greater than $1,500$ miles

Step-by-step explanation:

we know that

$1\ mile=63,360\ inches$

$1,500\ miles=1,500*63,360=95,040,000\ inches$

$240,000\ miles=240,000*63,360=15,206,400,000\ inches$

by proportion

Find the Moon's diameter

Let

x-----> the Moon's diameter in inches

$\frac{x}{15,206,400,000}=\frac{0.25}{30}\\ \\x= 15,206,400,000*0.25/30\\ \\x=126,720,000\ inches$

Compare

$126,720,000\ inches> 95,040,000\ inches$

therefore

The Moon's diameter is greater than $1,500$ miles
