Answer:
Formula for circumference: 2 x pie(3.14 or 22/7) x radius(half of diameter or already given radius). Area of a circle: pie(3.14 or 22/7) x radius squared
Radius: 3, 6 is diameter and half of that is 3.
3 x 3.14 x 2 = 18.84 <------ circumference
3.14 x 3^2
3.14 x 9 = 28.26 <------ area of the circle

A local grocery store stocks packages of plain M&M's and packages of peanut M&M's. The ratio of the number of packages of peanut M&M's to the total number of packages on the shelf was 8 to 18.
Which number could be the number of packages of plain M&M's on the shelf?
Answers
Answer:
30
Step-by-step explanation: Because each batch has 18 total m&ms and there are 8 in each batch minus and then multiply.
The number of packages of plain M&M's on the shelf could be any multiples of 5.
What is Ratio?Ratio is defined as the relationship between two quantities where it tells how much one quantity is contained in the other.
The ratio of a and b is denoted as a : b.
Given that,
Ratio of the number of packages of peanut M&M's to the total number of packages on the shelf = 8 : 18
That is, if there are total of 18 packages, 8 are peanut M&M's.
Number of plain M&M's out of 18 total packages = 18 - 8 = 10.
So,
Ratio of peanut M&M's to plain M&M's = 8 : 10
= 4 : 5
This indicates that, for a constant x,
Number of peanut M&M's = 4x
Number of plain M&M's = 5x
So the number of packages of plain M&M's on the shelf could only be the multiples of 5.
So it could be 5, 10, 15, 20, 25, 30, .......
Hence the number of plain M&M's on the shelf could be 5, 10, 15, 20, 25, 30, ......

What is the main cause of tides?
A.
Earth's gravitational pull
B.
the moon's gravitational pull
C.
the moon's rotation around its axis
D.
Earth's revolution around the sun
Answers
High tides and low tides are caused by the moon and tides are really all about gravity(hence why all of these answers have gravitational in them). And, when we are talking about "daily tides" it's the moon that causes them.
The moon's gravity draws in various areas of our world as it rotates. Since the moon is just 1/100th the mass of the Earth, it has enough gravity to shift objects about. The ocean on the moon's far side is still trying to bulge out against it. A high tide is what we term this bulge. (Water is easy to move around too)
This is tidal force, and there are differences between high tides and low tides.
The main cause of tides is the moon's gravitational pull.

the average can be calculated by adding the scores together and then dividing by the number of scores.
we can set up an equation:
let x = test score needed on next test
(72+72+80+x)/4 = 71
multiply both sides by 4
72+72+80+x = 284
add like terms
224+x=284
subtract 224 from both sides
x=60
she will need a 60 for her average to be 71
She needs to score a 60 to have a average score of 71,
72+72+80+60=284
284/4=71

View Available Hint(s) The density of mercury is 13.5 times greater than the density of water.

Answers
Answer:
h = 403.92in or 1026cm
Step-by-step explanation:
Given
Let x represent the density of mercury, and y the density of water.
[tex]y = 13.5x[/tex]
[tex]Mercury\ barometer =76cm[/tex] or [tex]Mercury\ barometer =29.92in[/tex]
Required
Determine the height of the barometer
At standard atmospheric pressure, the relationship between the mercury barometer and the height (h) of the barometer is:
[tex]h = 13.5 * Mercury\ barometer[/tex]
In centimeters, we have:
[tex]h = 13.5 * 76cm[/tex]
[tex]h = 1026cm[/tex]
In inches, we have:
[tex]h = 13.5 * 29.92in[/tex]

Which shows a correct comparison? A: 5 milliliters > 50 liters B: 2 liters < 200 milliliters C: 100 liters < 1,000 milliliteres D: 3,200 milliliters > 3 liters
Answers
Answer:
d
Step-by-step explanation:
Note that
> means greater than
< means less than
for example : 2 < 3 means 2 is less than 3
3 >2 means 3 is greater than 2
To determine which comparison is better we have to convert litre to millimetre
1 litre = 1000mm
A 5 mm > (50 x 1000)
5 mm > 50,000
5 is not greater than 50,000
B. (2 x 1000) < 200 mm
2000 < 200
2000 is not less than 200
C. (100 x 1000) < 1,000
100,000 < 1000
100,000 is not less than 1000
D. 3200 > (3 X 1000)
3200 > 3000
3200 is greater than 3000

You have to calculate the area of the base of the cylinder (the circle) by using the formula π r^2, r = the radius of the circle. You are squaring the r because r^2 = diameter. The formula to get the area of a circle is π r ^2. To get the volume you need to multiply the area of the circle by the height of the cylinder. All together the total formula to get the volume of a cylinder is π r^2 h
