Answer:
[tex]V=35.3\ m^3[/tex]
Step-by-step explanation:
-Given the cone's height is 9.1m and the Circumference is 12.1
#We use the circumference formula to calculate the radius:
[tex]C=2\pi r\\\\12.1=2\pi r\\\\r=\frac{12.1}{2\pi}=\frac{6.05}{\pi}\ cm[/tex]
-The volume of the cone using the radius above can then be calculated as follows:
[tex]V=\pi r^2\frac{h}{3}\\\\=\pi\times(\frac{6.05}{\pi})^2\times \frac{9.1}{3}\\\\\\=35.3\ m^3[/tex]
Hence, the cone's volume is [tex]35.3\ m^3[/tex]

Answer: I think the table has the greater rate of change because to find the greater rate of change we have to find the rate of change for both function. So, for this we have to find two points for both and then using the slope formula we have to solve for it.
for the first one: (4,6)(6,9)
9-6/6-4
3/2
For the second function: (4,5)(5,10)
10-5/5-4
5/1
5
so as we see that 3/2 is not greater than 5 so the function 3 has the greater one.
I don't know how to solve the first one. I am sorry but hope this helps you!

Step-by-step explanation:
Naomi owns a food truck that sells tacos and burritos. She sells each taco for $3 and each burrito for $5.25. Naomi must sell a minimum of $470 worth of tacos and burritos each day. Write an inequality that could represent the possible values for the number of tacos sold, tt, and the number of burritos sold, bb, that would satisfy the constraint.
Answer:
3t+5.25b≥470
Each taco sells for $3, so t tacos will bring in 3t dollars. Each burrito sells for $5.25, so b burritos will bring in 5.25b dollars. Therefore, the total amount of revenue 3t+5.25b must be greater than or equal to $470:
A school bought pens, each costing $1, and pencils, each costing $0.5. The cost of the whole purchase was $220. How many pens and pencils were purchased if there were 80 more pencils than pens?
Answer:
120 pens and 200 pencils.Explanation:
You can set a system of two equations.
1. Variables
x: number of pensy: number of pencils2. Cost
each pen costs $1, then x pens costs: xeach pencil costs $0.5, then y pencil costs: 0.5yThen, the total cost is: x + 0.5yThe cost of the whole purchase was $ 220, then the first equation is:x + 0.5y = 220 ↔ equation (1)
3. There were 80 more pencils than pens
Then:
pencils = 80 + pens
↓ ↓
y = 80 + x ↔ equation (2)
4. Solve the system
i) Substitute the equation (2) into the equation (1):
x + 0.5(80 + x) = 220ii) Solve
x + 40 + 0.5x = 2201.5x = 180x = 180/1.5x = 120 pensiii) Substitute x = 120 into the equation (2)
y = 80 + 120y = 200 pencilsSolution: 120 pens and 200 pencils ← answer
find y ..............

What is better buy
120 ounces of milk for $3
Or
600 ounces of milk for $ 13
Answer:
120 ounces of milk for $3 is a better buy
Step-by-step explanation:
Divide the total number of ounces by the price to find the price per ounce:
120 ÷ 3 = 40 cents per ounce
600 ÷ 13 = 46.15 cents per ounce
How is the total price including sales tax calculated?
a. (purchase price) < (percent sales tax); then added c. (purchase price) < (percent sales taxx); then divided
to original amount
by the original amount
b. (purchase price) (percent sales tax); then d. (purchase price) (percent sales tax); then
subtracted from original amount
multiplied by the original amount
Please select the best answer from the choices provided
Answer:
Sales tax is calculated by multiplying the cost of a good or service by the appropriate sales tax rate The answer is B (purchase price) (percent sales tax); then d. (purchase price) (percent sales tax). Hope it helps!:)
If you bought a stock last year for a price of $98, and it has gone down 17% since
then, how much is the stock worth now, to the nearest cent?
98 - 0.17(98)
98 - 16.66
81.34
The stock is now worth $81.34.

Find the total total surface area of the composite figure below with
r=2.2
l=10.2
h=8.7
Use 3.14 for LaTeX: \piπ.
Round to the nearest hundredth.
Pro tip: don't count the surfaces that are not exposed.
Given:
The radius of given fig = 2.2 unit
The height of the cylindrical part = 8.7 unit
The slant height of the cone = 10.2 unit
To find the total surface area of the given figure.
Formula
The given figure consists of a cylinder and a cone.
So, the surface area of the fig
[tex]SA = \pi r l+2\pi r h+\pi r^{2}[/tex]
Where, r be the radius
h be the height
l be the slant height
Now,
Putting,
r=2.2, h = 8.7, l=10.2 and π=3.14 we get,
[tex]SA = (3.14)(2.2)(10.2)+2(3.14)(2.2)(8.7)+(3.14)(2.2^{2} )[/tex] sq unit
or, [tex]SA = 70.4616+120.1992+15.1976[/tex] sq unit
or, [tex]SA = 205.8584[/tex] sq unit
or, [tex]SA = 205.86[/tex] sq unit
Hence,
The total surface area of the given figure is 205.86 sq unit.

0.75p=0.4+100
Answer:
p=133.866667
Step-by-step explanation:
Let's solve your equation step-by-step.
0.75p=0.4+100
Step 1: Simplify both sides of the equation.
0.75p=0.4+100
0.75p=(0.4+100)(Combine Like Terms)
0.75p=100.4
0.75p=100.4
Step 2: Divide both sides by 0.75.
0.75p/0.75 = 100.4/0.75
p=133.866667
Answer:
p=133.866667

Step-by-step explanation:
a trucker drove 500 miles in h hours. If the trucker averaged 60 mph, which linear equation could be used to find the number of hours that the trucker drove?
Step-by-step explanation:
Given that,
Distance covered by a trucker, d = 500 miles
Average speed of the trucker, v = 600 mph
A trucker drove 500 miles in h hours. We need to write the linear equation used to find the number of hours that the trucker drove. Average speed is given by :
[tex]v=\dfrac{d}{t}[/tex]
t is time in hours
[tex]t=\dfrac{d}{v}\\\\t=\dfrac{500\ miles}{60\ mph}[/tex]
If t is h hours,
[tex]h=\dfrac{500\ miles}{60\ mph}\\\\500=60h[/tex]
On solving, h = 5 hours.
Hence, this is the required solution.

Graph the line x=-2y-3. Find the
slope and the y-intercept.
Answer:
the slope is [tex]-\frac{1}{2}[/tex]
the y-intercept is [tex](0,-1.5)[/tex]
Step-by-step explanation:
(the website i used to graph it is called desmos)
After you graph the line, the y-intercept is the point on the line where it passes through the y-axis. On this line, that point is [tex](0,-1.5)[/tex]
To find the slope, an easy way would be to use "rise over run"
Find two points on the line and plug them into this equation: [tex]\frac{y_{1} -y_{2} }{x_{1} -x_{2} }[/tex], for this i used the points [tex](5,-4)[/tex] and [tex](7,-5)[/tex]
[tex]\frac{-4+5}{5-7} = -\frac{1}{2}[/tex]
so the slope is [tex]-\frac{1}{2}[/tex]

This composite figure has been divided into three rectangles. What is the area of this composite figure
Given:
A composite shape consisting of three rectangles with different lengths and widths.
To find:
The area of the composite shape.
Solution:
To find the area of the composite shape we must add the areas of all the three rectangles.
The upper rectangle has a length of 8 inches and a width of 4 inches.
The area of a rectangle [tex]= (l)(w).[/tex]
The area of the upper rectangle [tex]=(8)(4)=32[/tex] in².
The middle rectangle has a length of [tex]8-4=4[/tex] inches and a width of [tex]10-4-1.5=4.5[/tex] inches.
The area of the middle rectangle [tex]=(4)(4.5) = 18[/tex] in².
The lower rectangle has a length of 8 inches and a width of 1.5 inches.
The area of the lower rectangle [tex]= (8)(1.5)=12[/tex] in².
The area of the composite shape [tex]= 32+18+12 = 62[/tex] in².
The composite shape has an area of 62 in² which is option 3.
Answer: you have to do 62

If (t+10)+t=t+20, what is the value of t?
Answer:
t=10
Step-by-step explanation:
(t+10)+t=t+20,
Combine like terms
2t+10 = t+20
Subtract t from each side
2t-t+10 =t-t+20
t+10 =20
Subtract 10 from each side
t+10-10 = 20-10
t = 10
Answer:
t = 10
Step-by-step explanation:
2t+10 = t+20
-t -t
__________
t + 10 = 20
-10 -10

Ashley is making cookies for her Easter party. Each batch of cookies mix need 0.4 cups of sugar and each batch can make 16 cookies. If Ashley is making 4 batches of cookies, how much sugar does she need?
Answer:
1.6 cups
Step-by-step explanation:
Each batch needs 0.4 cups of sugar, and she is making 4 batches. Therefore, we can multiply 0.4 times 4 to find how much sugar is needed.
0.4*4=1.6
So, she needs 1.6 cups of sugar for 4 batches
Answer:
1.6 cups of sugar for four batches of cookies
