Answer:[tex]376.80\ mm^3[/tex]
Step-by-step explanation:
Given
The height of the cone is [tex]h=10\ mm[/tex]
The radius of the cone is [tex]r=6\ mm[/tex]
Volume of cone is given by
[tex]V=\dfrac{1}{3}\pi r^2h[/tex]
Insert the values
[tex]\Rightarrow V=\dfrac{1}{3}\times 3.14\times 6^2\times 10\\\\\Rightarrow V=376.80\ mm^3[/tex]
Thus, the volume of the cone is [tex]376.80\ mm^3[/tex]
Isabel is buying framing to go around the perimeter of one of her paintings. Each inch of framing costs $0.40. What is the total cost of the framing for the pantings
I have added the complete question. That is in the attachment
Answer:
$13.2
Step-by-step explanation:
Cost of 1 inch = $0.4
Perimeter of painting is same as perimeter of a rectangle since painting is a rectangle
Perimeter = 2(l+b)
L = 10¼
B = 6¼
P = 2(10¼ + 6¼)
P = 2(41/4 + 25/4)
P = 2(10.25 + 6.25)
P = 2(16.5)
P = 33
Total cost of framing
= 0.4 x 33
= $13.2

Answer:
VWU and FWT are vertical angles.
Their measure is same and:
VWU = 1/2(mVU + mFT)x = 1/2(174° + 52°)x = 113°Brad and Don went to the mall together. Brad spent $18 on food. Don spent twice the amount of money that Brad spent.
a) Write an algebraic equation to express how much Don spent and solve the equation you made.
b) Brad's sister had gone to the mall the day before and spent 30% of what Don did. How much did she spend?
c) If the tax rate was 13% how much of what Don and Brad spent was for tax?
Answer:
a). x=18x2
18x2=36
Don spent 36 dollars.
b). x=36x0.3
36x0.3=10.8
Brad's sister spent 10 dollars and 80 cents.
c). 36+18=54
1.0-0.13 = 0.87
54x0.87=46.98
54-46.98=7.02
Don and Brad paid 7 dollars and 2 cents in tax.

What is the difference between the highest percent of votes received by student in the lowest percent of votes received by a student? Round to the nearest whole number if needed.
A. 20%
B. 8%
C. 35%
D. 15%
Answer:
A) 20%
Step-by-step explanation:
The total votes are:
40 + 70 + 60 + 90 = 260
Rebecca has the highest percent of votes which is 90 votes. To find the %:
90/260 ≈ 34.62%
Amy has the lowest percent of votes which is 40 votes.
40/260 ≈ 15.38%
Finding the difference:
34.62 - 15.38
19.24
So, it's around 20%

-Chetan K
Answer:
x = 78
Step-by-step explanation:
The angle labeled x and the angle with a measure of 78° are vertical angles
Vertical angles are congruent ( equal to each other )
So if "x"'s vertical angle has a measure of 78 degrees than x also has a measure of 78 degrees.

Variable p is 2 less than variable d. Variable p is also 1 more than variable d. Which pair of equations best models the relationship between p and d? (5 points)
a
p = d + 2
p = d − 1
b
p = d − 2
p = d + 1
c
d = 2p
d = 2p − 1
d
d = 2p
d = 2p + 1
Answer:
b)
p = d − 2
p = d + 1
Step-by-step explanation:
From the above question:
Interpreting the statement above to form algebraic expressions, we have:
Variable p is 2 less than variable d.
Less than means to subtract in this context
p = d - 2
Variable p is also 1 more than variable d
More than means to add in this context
p = d + 1
Therefore, the pair of equations tha best models the relationship between p and d is Option b :
p = d − 2
p = d + 1

Each side of a square x units long is decreased by 9 units. Which expression represents the area of the new square in square units? *
Given:
Side of a square = x units
The side of square is decreased by 9 units.
To find:
The expression that represents the area of the new square in square units.
Solution:
It is given that, the side of a square is x units and it is decreased by 9 units. So, the side of new square is:
[tex]\text{New side length}=x-9[/tex]
The area of a square is:
[tex]Area=(side)^2[/tex]
So, the area of the new square is:
[tex]Area=(x-9)^2[/tex]
[tex]Area=(x)^2-2(x)(9)+(9)^2[/tex] [tex][\because (a-b)^2=a^2-2ab+b^2][/tex]
[tex]Area=x^2-18x+81[/tex]
Therefore, the expression for the area of the new square is either [tex](x-9)^2[/tex] or [tex]x^2-18x+81[/tex], both are equivalent.

I think this is correct and what you wanted
(trigonometry) solve for x
Answer:
[tex]x = 21 \sin(38 \degree) \\ x = 12.93[/tex]
The more accurate value is roughly x = 16.5482258257411
=====================================================
Work Shown:
cos(angle) = adjacent/hypotenuse
cos(38) = x/21
21*cos(38) = x
x = 21*cos(38)
x = 16.5482258257411 which is approximate
x = 17
I'm rounding to the nearest whole number since the other side (21) is a whole number. If your teacher instructs you to round otherwise, then follow those instructions of course. Make sure your calculator is in degree mode.

Sarah walks uphill at an average of 2 miles per hour, and downhill at an average of 4 miles per hour. She goes for a 6 mile hike up a hill, and then returns downhill by the same route. What is Sarah's average speed for the whole journey?
Answer:
48
Step-by-step explanation:
Answer:
Average of 3mph
Step-by-step explanation:
If Sarah goes uphill at 2mph and downhill at 4mph.
Then to find the average you can:
Add 2 plus 4
which equals 6
Then divide the sum of 6 by the number of values given, there are two values (2 and 4)
6 divided by 2 equals 3
So the average is 3mph

Each backpack in a store is on sale for $5 off the original price. How does this affect the median price?
Answer:
this would cause the median price to go down by $5 as well.
Step-by-step explanation:
If every single backpack in the store is on sale, then this would cause the median price to go down by $5 as well. This is because the median price is the middle value in a data set. Therefore, if every backpack value drops by $5 then so does the backpack that has the middle value and is the median price of all the backpacks. This is the only actual effect that this sale will have to the median price of the backpacks.

Find the measure of the central angle of an arc
with length 5n units and radius of 4.5 units.
Answer:
Theta = 10n/9 radians.
Step-by-step explanation:
The length is 5n units
Radius is 4.5 units
center angle is, S = r * theta
5n = 4.5 * theta
Theta = 5n/4.5
= 50n/45
= 10n/9
A spinner has 8 equal-sized sections. Six of the sections are green. What is the probability that the spinner will land on green?
_________ out of 8 or ________%
Answer:
6/8
Step-by-step explanation:
or to simplify it, it would be 3/4
The probability that the spinner will land on green is 6 out of 8 or 75%.
What is Probability?Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.
The value of probability will be always in the range from 0 to 1.
Given that,
Number of equal sections on the spinner = 8
Number of sections which are green = 6
Probability can be calculated as the ratio of number of desired outcomes to the total number of outcomes.
Here,
Desired outcome is the spinner landing on green.
Probability = 6/8 = 0.75 = 75%
Hence the probability is 6 out of 8 or 75%.

How do you calculate the Monthly Share of Annual Expenses? What would they be if the annual expenses were $27,987? (Show Your Work)
Answer:
$2332.25 per month
Step-by-step explanation:
1) The monthly share of annual expenses can be calculated from the annual expenses. Since there are 12 months in a year, the monthly share of annual expenses is gotten by dividing the annual expenses by the number of months in a year.
2) The monthly share of annual expenses is given by:
Monthly share of annual expenses = Annual expenses / 12 months
Monthly share of annual expenses = $27987 / 12 months = $2332.25 per month

The Seventh Inning Stretch Company has created a new baseball that will improve your chances of hitting a home run. The 36-inch bat is only available online. To protect the bat, it must be shipped so the handle of the bat is in one corner of the box and the top portion of the bat touches the opposite diagonal corner.The shipping box has a length of 30 inches and a height of 6 inches. How wide should the box be to fit the 36-inch bat? Show and explain your work.
Answer:
Width of the box = 18.97 inches
Step-by-step explanation:
Length of the bat = 36 inches.
That means length of the diagonal of the bat (BC) = 36 inches
By applying Pythagoras theorem in right triangle BDC,
BC² = BD² + CD²
BC² = (30)² + w² -------(1)
BY applying Pythagoras theorem in right triangle ABC,
AC² = AB² + BC²
(36)² = 6² + BC²
By substituting the value of BC from equation (1),
(36)² = 6² + (30)² + w²
1296 = 36 + 900 + w²
w² = 1296 - 936
w = √360
w = 18.97 inches
