Answer:
see below
Step-by-step explanation:
72pi cubic inches
1/3 pi r ^2 * h = 72 pi
1/3 r^2 h = 72
You can theoretically find infinite answers to this and get enough points for the semester where you don't have to do work anymore. I will list a couple more possible answers below
r = radius, h = height
r = 2, h = 54
r = 3, h = 24
r = 4, h = 27/2
r = √(1/pi), h = 72pi
Answer:
A) y = 1 - 2x
Step-by-step explanation:
Substitute the points given into all of the equations
Let's take point (1, -1)
A) y = 1 - 2x
-1 = 1 - 2(1)
-1 = 1 - 2
-1 = -1 ✓
B) y = -x - 1
-1 = -1 - 1
-1 = -2 ✘
C) y = x - 2
-1 = 1 - 2
-1 = -1 ✓
D) y = 2x - 1
-1 = 2(1) - 1
-1 = 2 - 1
-1 = 1 ✘
So far, lines A and C can be possible solutions. Let's try point (2, -3)
A) y = 1 - 2x
-3 = 1 - 2(2)
-3 = 1 - 4
-3 = -3 ✓
C) y = x - 2
-3 = 2 - 2
-3 = 0 ✘
Thus, line A is the correct answer
Answer:
310 cones sold
Step-by-step explanation:
Out of the 3:5:2 ratio, the 155 chocolate represents the 5 in there
We should find the value of "1" by dividing 155 by 5
155 divided by 5 is 31
Now we know the base value is 31, keep this in mind because we will need it later
Since we are trying to find the total number of cones sold, we should add all the ratio numbers together
3+5+2=10
Now that we know the total is "10", we just have to multiply 31 by 10
31x10=310
310 cones sold
Answer:
We get the value of a: 
Step-by-step explanation:
We have to solve the inequality 
So, solving the inequality and finding value of a
First step is to switch both sides and for doing so, the inequality will be reversed
Multiply both sides by -2, as we are multiplying by a negative number, the inequality will be reversed
Now, subtracting both sides by 7, to find value of a
We get the value of a:
