Answer:
12 mouthpieces, 24 reeds, 6 neck straps
Step-by-step explanation:
42 objects - 12 mouthpieces
= 30 objects left consisting of reeds and neckstraps
4 times as many reeds as neckstraps
think of it as 5 groups, 4 are reeds and 1 of nexkstraps
so divide 30 by 5 to get 6 per part.
4 of those parts = 24
1 of the parts = 6
so reeds = 24
neckstraps is 6
mouthpieces = 12
Answer:
Computing the sum of $5.89 and $1.45 we get: $7.34
Step-by-step explanation:
We need to explain, how can we compute the sum of $5.89 and $1.45?
Computing the sums of dollar amounts is same as computing the sum of simple decimal expressions. Each value will be added to its corresponding values and we will get the answer.
Computing the sum of $5.89 and $1.45
![\:\:\:\:\:\$ \:\:5.89\\+\$ \:\:1.45\\------\\\:\:\:\:\:\$ \:\:7.34](https://tex.z-dn.net/?f=%5C%3A%5C%3A%5C%3A%5C%3A%5C%3A%5C%24%20%5C%3A%5C%3A5.89%5C%5C%2B%5C%24%20%5C%3A%5C%3A1.45%5C%5C------%5C%5C%5C%3A%5C%3A%5C%3A%5C%3A%5C%3A%5C%24%20%5C%3A%5C%3A7.34)
So, we will start adding from right side, 9 will be added with 5 and we get 14, 1 will be given carry and 8 will be added by 4 and add the carry we get 13, 1 will be given carry and 1 will be added by 5 and add the carry we get 7
So, Computing the sum of $5.89 and $1.45 we get: $7.34
Answer:
R(p) = -6p^2 + 60p....
Step-by-step explanation:
Revenue, R = quantity sold * price
Price = p
Quantity sold = q = -6p + 60
R(p) = q*p
where q=-6p + 60
= (-6p + 60) * p = -6p^2 + 60p
Answer: R(p) = -6p^2 + 60p....
Both are parabolas, vertex at origin, 4x^2 is concave up and the other is concave down
hope that helps
