Answer:

between 0 and 1

Step-by-step explanation:

The big key to this is that the negative sign in front of the two is NOT in parentheses along with the 2.

We follow the order of operations - PEMDAS - parentheses, exponents, multiplication and division, addition and subtraction.

So, inside the parentheses, the first thing we do is the exponent. We raise 2 to the third power and get 8.

Next, still inside the parentheses, we now multiply by negative 1. That is what putting a negative sign in front of something really is - multiplying by -1.

So now inside the parentheses, we have -8.

-8 raised to the power -2 is one over (-8) raised to the power positive 2.

That is one over 64,

That is more than zero, but less than one.

I have the math written out in an attached picture (I hate the equation writer on this website.) Haha.

What is x equal to in the problem 10+3(x+2)=36? Please show your work.

scZoUnD [109]

Answer:

x = 6 2/3

Step-by-step explanation:

10+3(x+2)=36

10+3x+6=36 Solve inside the parenthesis.

16+3x=36 Combine like terms.

-16 -16 Subtract 16 from both sides.

3x/3=20/3 Divide both sides by 3.

x=6 2/3 The answer is x= 6 2/3, or 6.66666666666667

A
Volume of the Cylinder
Givens
H = 60 yards.
Diameter = 20 yards
pi = 3.14

Formula
V = pi * r^2 * h

Calculations
r = d/2
r = 32/2
r = 16

V = 3.14 * 16^2 * 60
V = 48230 cubic yards [Cylinder's Volume]

Cone
Formula
V = 1/3 pi r^2 H

Givens
pi = 3.14
r = 16 yards
h = 20 yards

Sub and solve
V = 1/3 3.14 * 16^2 * 20
V = 5359 cubic yards.

Total Volume of the structure
48230 + 5359 = 53589 Cubic Yards

Water Content
The answer to this part requires a proportion.

1 Cubic yard will hold 201.97 gallons.
53589 yd^3 = x

1/201.97 = 53589 /x [ You should get a pretty big answer]
x = 201.87 * 53589
x = 10 819 092 gallons can be held by the tank.

10 819 092 gallons <<<< answer

B
If the height of both the cylinder and the cone remain the same. If the radius doubles in both the cylinder and the cone then the tank will hold 4 times as much.

Total volume before doubling the radius = pi * r^2 h + 1/3 pi r^2 h
New Total Volume = pi * (2*r)^2 h + 1/3 pi * (2r)^2 h
New Total volume = pi * 4r^2 h + 1/3 pi *4 r^2 h
New Total Volume = 4 [pi r^2 h + 1/3 pi r^2 h]
but pi r^2 h + 1/3 pi r^2 h is the total volume before doubling the radius

New volume = 4 original volume. <<<<< answer to part B

Solve the system of equation by the addition method x-2y=11 and -x+6y =-31

Sonbull [250]

Answer: x = 1, y = - 5

Step-by-step explanation:

The given system of linear equations is expressed as

x - 2y = 11- - - - - - - - - - - - -1

- x + 6y = - 31- - - - - - - - - - - -2

We would eliminate x by adding equation 1 to equation 2. It becomes

- 2y + 6y = 11 - 31

4y = - 20

Dividing the the left hand side and the right hand side of the equation by 4, it becomes

4y/4 = - 20/4

y = - 5

Substituting y = - 5 into equation 1, it becomes

x - 2 × - 5 = 11

x + 10 = 11

Subtracting 10 from the left hand side and the right hand side of the equation, it becomes

x + 10 - 10 = 11 - 10

x = 1

Can someone help on this one because i don’t know if i’m correct

34kurt

Answer:

Yes its C

Step-by-step explanation:

First off the y intercepts + 3 and the line hits it not -3 so option D is out

Also the slope is negative so Option A and B are out
