There are 45 pounds and 30 pounds of each type respectively.
Step-by-step explanation:
Since we have given that
Cost of first type = $2 per pound
Cost of second type = $7 per pound
Cost of mixture = $4 per pound
So, we need to find the quantity of each type to make 75 pounds of a blend.
We will use "Mixture and Allegations":
First type Second type
2 7
4
---------------------------------------------------
7 - 4 : 4 - 2
3 : 2
So, Quantity of first type would be

Quantity of second type would be

Hence, there are 45 pounds and 30 pounds of each type respectively.

Answer:
(2, 3)
Step-by-step explanation:
Compare the given equation ...
y = (x -2)^2 +3
to the vertex form ...
y = (x -h)^2 +k
You can see that h=2 and k=3.
The vertex of the parabola is (h, k) = (2, 3).
Answer:
<h2>30 ft. tall</h2><h2 />
Step-by-step explanation:
ratio and proportion:
<u>20 ft. long</u> = <u> 4 ft. long</u>
x tall 6 ft. tall
4 (x) = 20 (6)
x = 120 / 4
x = 30 ft. tall
