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

The length of each side of an equilateral triangle is increased by 20%, resulting in triangle ABC. If the length of each side of

kompoz [17]

Answer: Area of ΔABC is 2.25x the area of ΔDEF.

Step-by-step explanation: Because equilateral triangle has 3 equal sides, area is calculated as

$A=\frac{\sqrt{3} }{4} a^{2}$

with a as side of the triangle.

Triangle ABC is 20% bigger than the original, which means its side (a₁) measures, compared to the original:

a₁ = 1.2a

Then, its area is

$A_{1}=\frac{\sqrt{3} }{4}(1.2a)^{2}$

$A_{1}=\frac{\sqrt{3} }{4}1.44a^{2}$

Triangle DEF is 20% smaller than the original, which means its side is:

a₂ = 0.8a

So, area is

$A_{2}=\frac{\sqrt{3} }{4} (0.8a)^{2}$

$A_{2}=\frac{\sqrt{3} }{4} 0.64a^{2}$

Now, comparing areas:

$\frac{A_{1}}{A_{2}}= (\frac{\sqrt{3}.1.44a^{2} }{4})(\frac{4}{\sqrt{3}.0.64a^{2} } )$

$\frac{A_{1}}{A_{2}} =$ 2.25

<u>The area of ΔABC is </u><u>2.25x</u><u> greater than the area of ΔDEF.</u>
