Answer:
1. 14476.46
2. 25333.8
3. 19142.66
Step-by-step explanation:
Ok lets take this slow...
First, read the directions; they want you to find how much water the barrles will hold, also meaning how much space is inside the barrel? This can be a hint to find for the area of the barrles.
The formula for a cyliner is: A=2πrh+2πr^2
You already have the information to solve the formula so all you have to do is plug the amounts in, whitch would look like this.
A= 2(3.14) (72) + 2(3.14) (24) ^2
72 * 3.14 24 * 3.14
A= 2 (226.08) + 2(75.36)^2
452.16 + 2 (5679.1296)
452.16 + 11358.2592
A≈ 14476.46
You would do the same for barel B and get: 25333.8
now subtract Barral A by Barral B to find the diffrence
144476.46 - 25333.8
The diffrent of barrle A and B is 19142.66
Answer:
On a coordinate plane, a dashed straight line has a positive slope and goes through (negative 4, 2) and (4, 4). Everything below and to the right of the line is shaded.
Step-by-step explanation:
The first step is writing in the general form of the first order equation
y = f(x) or y > f(x) or y < f(x)
And
f(x) = ax + b
In which a is the slope.
We have that:
x - 2y > -6
-2y > -6 - x
When multiplying by -1, the signal changes, from > to <
2y < x + 6
y < 0.5x + 3
The slope is positive, since 0.5 is positive.
Since it is y lesser than, it is everything below and to the right of f(x) is painted.
The line is dashed because this is just lesser, not lesser or equal.
The correct answer is:
On a coordinate plane, a dashed straight line has a positive slope and goes through (negative 4, 2) and (4, 4). Everything below and to the right of the line is shaded.
