The hardware store sells copper pipes for $24 per 5 feet right? so, 5 feet is equal to 60 inches and since you need 6 inches, you divide 60 by 10 to get 6 and also divide 24 by ten and you get 2.4, so the answer is $2.4 for 6 inches of pipe.
Hope this helps!
Answer:
25,
8:5
4:3
Step-by-step explanation:
you have to model it as a system of equations.
first, we know there are a total of 65 children, boys and girls. so
we also know there are 15 more boys than girls so
now, we can plug the second equation into the first to get
so
if g = 25, b must = 40, because it is g+15.
the ratio will be 40 boys to 25 girls. 40:25 or 8:5 if you simplify.
if there are 5 more girls, g = 25+5 = 30, so the ratio is 40:30 or 4:3.
Answer:The vertex form is -y=a(x-h)2+k

Answer:
Step-by-step explanation:
Given:
Length of ladder, y = 10 ft
θ = π/3 rad
Using cosine rule,
Sin θ = opposite/hypotenuse
Sin θ = x/y
Sin θ = x/10
Differentiating both sides with respect to dθ,
10 × cos θ × dθ = dx
10 cos θ = dx/dθ
dx/dθ = 10 × cos π/3
= 5 ft/radians.
Answer:
-2700 dollars
Step-by-step explanation:
The first year we have a loss of 1500 dollars. On the balance sheet we write -1500, with the negative indicating loss. Some accounting practices will use parenthesis to mean loss, so you might see it as (1500). But in this problem, we'll use negative signs for loss.
The second year is loss of 1200. Add up the two losses (the positive versions of each) to get 1500+1200 = 2700. Then make the result negative. Taking one loss and adding more loss to it means your loss has gotten bigger. So that's why the closing balance at the end of year 2 is -2700 dollars, which is a loss of 2700 dollars.
