Can someone help me
Answer:
C. there is no solution
Step-by-step explanation:
Add 6 to both sides:
2x- 6 + 6=2x +5 + 6
Simplify equation above:
2x=2x+11
Subtract 2x from both sides:
2x - 2x=2x+11 -2x
Simplify equation above:
0 = 11
The sides are not equal, Therefore there is no solution :(
A rectangular prism has a length of 20 centimeters, a height of 10 centimeters, and a width of 20 centimeters. What is its volume, in cubic centimeters?
Answer: 4000 cm^3
Step-by-step explanation:
The volume of a rectangular prism is the length*width*height.
We can plug in the values given:
Volume = 20 cm * 20 cm * 10 cm
Volume = 4000 cm^3
Marie has bought a plant which she needs to transfer from its cylindrical pot to the ground. The pot has diameter 10 cm and is 21 cm high. Marie needs to dig a hole 4cm wider and 5cm deeper than the pot. She then inserts the plant and fills in the rest of the hole with extra soil. (i) Calculate the volume of the hole Marie needs to dig. (ii) Before inserting the plant, Marie fills the hole with water. How much water will she need, assuming none of it soaks away? (iii) Marie is planning to paint the outside of the cylindrical pot excluding the top and bottom. Calculate the area to be painted
Using known formulas for cylinders, we will get:
i) 4,000.36 cm^3ii) 4,000.36 cm^3iii) 1,142.96 cm^2.Working with cylinders:
We know that the pot has a diameter of 10cm and a height of 21 cm, and the hole must be 4 cm wider (so the diameter is 14cm) and 5 cm deeper (so the height is 26cm).
i) The volume of a cylinder of radius r and height H is given by:
V = pi*r^2*H
Where pi = 3.14, and the radius is half the diameter, so we have:
r = 14cm/2 = 7cm.
Then the volume is:
V = 3.14*(7cm)^2*26cm = 4,000.36 cm^3
ii) To fill a volume of 4,000.36 cm^3, you need 4,000.36 cm^3 of water.
iii) The curve surface of a cylinder is given by:
S = 2*pi*r*H
Remember that:
r = 7cm
H = 26cm.
Replacing that we get:
S = 2*3.14*7cm*26cm = 1,142.96 cm^2
So se must paint an area of 1,142.96 cm^2.

A lawn sprinkler sprays water 4 feet in all direction as it rotates.
Find the area of the lawn the sprinkler covers. Use 3.14 for pi.
Answer:
50.24 ft^2
Step-by-step explanation:
The radius of the circle in which the lawn sprinkler sprays water is 4 feet.
The formula to find the area of a circle is [tex]\pi r^2[/tex], where r = radius and π, in this case, is 3.14.
3.14 × 4^23.14 × 1650.24 ft^2Therefore, the answer is 50.24 ft².

Had he thrown the hammer down, the story would be different!
Answer:
I am sorry if this wrong. I believe the initial velocity is 20.
Step-by-step explanation:
My reasoning is because the -16t^2 is representing the time. The h for height we are trying find the height. So that leave us with the initial velocity 20.

Solve the system of linear equations.
6x+2y=16
2x - y = 2
Do I put into point slope form??
Answer:
The simple answer, "Yes"
Answer:
Point slope form of the equations:
y = -3x + 8
y = 2x - 2
Solution to the system of equations:
(x, y) ==> (2, 4)
Step-by-step explanation:
6x + 2y = 16
2x - y = 2
6x + 2y = 16
2(2x - y = 2) ==> 4x - 2y = 4
6x + 2y = 16
4x - 2y = 4
10x = 20
/10 /10
x = 2
Now, we solve for y:
6x + 2y = 16
6(2) + 2y = 16
12 + 2y = 16
-12 -12
2y = 4
/2 /2
y = 2
(x, y) ==> (2, 2)
Point-slope forms:
6x + 2y = 16
-6x -6x
2y = -6x + 16
/2 /2
y = -3x + 8
2x - y = 2
-2x -2x
-1y = -2x + 2
/-1 -1
y = 2x - 2

The county health inspector will select a random sample of 4 community swimming pools in the county to investigate the pH levels. (b) Describe the sampling distribution of the sample mean for samples of size 4.
Using the Central Limit Theorem, considering a normally distributed population with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution is normal, with mean [tex]\mu[/tex] and standard deviation [tex]0.5\sigma[/tex].
Central Limit TheoremThe Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
Hence, considering a normally distributed population with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], and with the sample size of n = 4, the mean remains the same while the standard deviation is given by:
[tex]s = \frac{\sigma}{\sqrt{4}} = 0.5\sigma[/tex]
