Answer: 63.62 square m.
Step-by-step explanation:
Find the Radius so 9/2= 4.5
Area = π r²
Area 3.14(20.25)
Area equles 63.62
Answer:
1 quart = .947 L
3 Q = 2.841 L
So you should use 2.841 L to dissolve the powder
Answer:
18, 19, 20, 21
Step-by-step explanation:
Just like any of these problems, we should start by forming an equation for us to get a reference and plug in. We'll be using x as our variables.
As we have four consecutive integers (and not multiples) we can assume that the integers will be x, x+1, x+2, and x+3.
The sum of the two largest integers we have equals: n+2 + n+3 = 2n+5
and three times the sum of the two smallest = 3(n + n+1) = 6n+3
and the sum of t he two largest subtracted from three times the sum of the two smallest = (6n+3) - (2n+5) = 4n-2
4n-2=70
4n=68
n = 18.
n = 18, n+1 = 19, n+2 = 20, n+3 = 21
