Work Shown:
[tex]V = \pi*r^2*h\\\\V = \pi*3^2*6\\\\V = \pi*9*6\\\\V = \pi*54\\\\V = 54\pi\\\\[/tex]
This is the exact volume in terms of pi.
To find an approximation, replace pi with something like 3.14 and simplify.
The units for the volume are in cubic centimeters, which can be abbreviated to "cubic cm" or to [tex]\text{cm}^3[/tex]

The points (-6,r) and (2,5) lie on a line with slope -1/4. Find the missing coordinate r.
Answers
Answer:
r = 7
Step-by-step explanation:
Calculate the slope using the slope formula then equate to - [tex]\frac{1}{4}[/tex]
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 6, r ) and (x₂, y₂ ) = (2, 5 )
m = [tex]\frac{5-r}{2-(-6)}[/tex] = [tex]\frac{5-r}{2+6}[/tex] = [tex]\frac{5-r}{8}[/tex] , then
[tex]\frac{5-r}{8}[/tex] = - [tex]\frac{1}{4}[/tex] ( multiply both sides by 8 to clear the fractions )
5 - r = - 2 ( subtract 5 from both sides )
- r = - 7 ( multiply both sides by - 1 )
r = 7
Answer:
[tex]\displaystyle 7[/tex]
Step-by-step explanation:
[tex]\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m\\ \\ \frac{-r + 5}{6 + 2} = m \Rightarrow \frac{-r + 5}{8} \hookrightarrow -\frac{2}{8} = -\frac{1}{4} \\ \\ \boxed{7 = r}[/tex]

Find the average rate of change of g(x)=2x2-8x from x=2 to x=5
Answers
Answer:
The average rate of change is 20.
Step-by-step explanation:
To find the answer, plug in the 2 and 5 for x.
g(2) = 2(2)^2 - 8(2)
g(2) = 16 - 16
g(2) = 0
g(5) = 2(5)^2 - 8(5)
g(5) = 100 - 40
g(5) = 60
g(5)-g(2)/5-2 = the average rate of change
60/3=20

A bag contains 8 blue marbles, 6 green marbles, 12 yellow marbles, and 10 orange marbles. A marble is drawn at
random from the bag.
What is the probability that the marble drawn will not be blue?
A. 2/6
B.3/4
C.7/6
D.7/8
Answers
Answer:
7/9
Step-by-step explanation:
If the marble is not blue, the marble is either green, yellow or orange. That means we can add up 6, 12, and 10 to get 28. The total number of marbles in the bag is 36.
The probability that the marble will not be blue is 28/36. This can be simplified to 7/9

Each week Raisa earns $5.25 for doing chores. After saving money for 12 weeks, Raisa spends $13.45. How much money does Raisa have left?
Answers
Answer:
$49.55
Step-by-step explanation:
She earns $5.25 every week for 12 weeks, so we multiply her weekly income by 12.
$5.25 * 12 = $63.00
Then she spends $13.45, so we deduct that from her earnings.
$63.00 - $5.25 = $49.55
That shows us that she has $49.55 left.

3/4 of a number is greater than 3/16 of the same number by 81. What is 1/2 of the number?
Answers
Answer:
72
Step-by-step explanation:
The given word description can be translated to math symbols this way, when x represents the number:
3/4x -3/16x = 81
Multiplying by 16 gives ...
12x -3x = 1296
9x = 1296 . . . . . . simplify
We want to find the value of half the number, so we can divide this by 18 to get ...
x/2 = 1296/18 = 72
Half the number is 72.

Which is the volume of the solid? The solid is made up of 2 cuboids. First cuboid has length as 4 unit cubes, height as 1 unit cubes and width as 2 unit cubes. Second cuboid has length as 1 unit cube, height as 3 unit cubes and width as 2 unit cubes.
A. 14 cubic units
B. 16 cubic units
C. 21 cubic units
D. 35 cubic units
Answers
Answer:
14 cubic units
Step-by-step explanation:
The Formula for Volume is
V = L x W x H
Since there are 2, you need to add the two totals together.
Cubic one:
4 x 1 x 2 = 8 (it also doesn't matter what order you put your numbers in, you will still get the same outcome. Its called the commutative property of multiplication)
Cubic Two:
1 x 3 x 2 = 6
Now just add the totals together:
6 + 8 = 14
Here, we have to find the volume of the solid which is made up of two cuboid. We know that the volume of cuboid is given by:
V = l × w × hThe volume of the solid will be equal to the sum of volume of given two cuboid
For 1st cuboid :
l = 4 unit h = 1 unit w = 2 unitTherefore, Volume:
➝ V = l × w × h
➝ V = 4 × 2 × 1
➝ V = 8 unit³
For 2nd cuboid:
l = 1 unitw = 2 unitsh = 3 unitsTherefore, Volume:
➝ V = l × w × h
➝ V = 1 × 2 × 3
➝ V = 6 unit ³
Now, Volume of solid :
ㅤㅤㅤ➙ sum of V of cuboid
ㅤㅤㅤ➙ 8 + 6
ㅤㅤㅤ➙ 14 unit ³
