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?
Answers
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
Consider these scenarios. 1. An elephant weighs 1. 5 × 104 units. 2. A mouse weighs 2. 13 × 10-5 units. 3. A puppy weighs 1. 2 × 102 units. Determine the unit of measurement that best represents each scenario. 1. 2. 3.
Answers
An ounce unit will best represent each scenario.
The average weight of an elephant is around 3000-4000 kg.
The average weight of a mouse = 15-20 grams
The average weight of a puppy = 25-30kg
It is given that
Weight of the elephant = [tex]1.5 * 10^5[/tex] units ≈150000 units
Weight of the mouse = [tex]6.3*10^2[/tex] units ≈630 units
Weight of the puppy = [tex]1.2*10^3[/tex] units ≈1200 units
What is the relation between an ounce and a kg?1 ounce = 0.0253495 kg
150000 ounces = 3800kg, near to actual value
630 ounces = 16kg, near to actual value
1200 ounces = 30kg, near to actual value
Therefore, an ounce unit will best represent each scenario.

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
Answers
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.

10 small and 8 large cost $192. 20 small and 1 large cost $99. What is cost of a small
Vhat is cost of a large?
Answers
Answer:
Step-by-step explanation:
small=s, s=3.99
large=l, l=19.20
10s+8l=192.20
20s+l=99
we can see that in the second equation, 20s+l=99
l=99-20s
lets replace l in the first equation
10s+8(99-20s)=192.20
10s+792-160s=192.20
-150s=-792+192.20
150s=599.80
s=3.99
l=99-20(3.99)=99-79.80=19.20
Answer:
19
Step-by-step explanation:
You can set up a system of equations.
x=small, and y = large.
10x+8y=$192
20x+1y=$99
you can multiply the first equation by -2 to get rid of x:
20x+1y=$99
-20x-16y=-$384
when you combine them, you get:
-15y=$-285
you can divide by -15 and you get:
y=19, so 1 large equals $19

c is the y intercept
m is
m is rise/run
the line rises from 3 to 10
so rise is 7
the line runs from 0 to 3.5
so run is 3.5
m = 7/3.5
m = 2
c is

Answer:
$33.91
Step-by-step explanation: Take 35% and change it to .35 now multiply 96.88 by .35 and you will get 33.908 round up to 33.91
Answer:
33.908
Step-by-step explanation:
To find the percentage of a certain number, you need to convert the percentage into its decimal form (0.35) and multiply it by the certain number. Then you'll have your answer!
0.35*96.88=33.908
33.908 is 35% of 96.88
Here's another example! Let's say you want to find 45% of.... 78!
45% is 45/100. The first step is to convert 45% into its decimal form. (45/100=0.45)
Then you multiply the decimal by the number you want to find the percentage of!
0.45*78=35.1
35.1 is 45% of 78!

Do I put into point slope form??
Answers
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.
Answers
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]
