Answer:
yes
Step-by-step explanation:
You can do this several ways. One is to divide the volume by the rate of filling to see if the time is less than 15 minutes. Another is to find the volume filled in 15 minutes and see if the hemisphere has less volume than that.
Volume of the hemisphere:
V = 2/3πr³
V = 2/3π(30 cm)³ ≈ 56,548.7 cm³
The time to fill it will be ...
V = 56,548.7 cm³/(4000 cm³/min) ≈ 14.14 min
Yes, it takes less than 1/4 hour to fill the container.
Answer:
yes it takes less than 15 mins
Step-by-step explanation:
V ( hemisphere ) = [tex]\frac{1}{2}[/tex] × [tex]\frac{4}{3}[/tex] πr³ = [tex]\frac{2}{3}[/tex] πr³ , then
V = [tex]\frac{2}{3}[/tex] × π × 30³
= [tex]\frac{2}{3}[/tex] × π × 27000
= 2π × 9000
= 18000π
≈ 56548.7 cm³
Time to fill = [tex]\frac{56548.7}{4000}[/tex] ≈ 14 minutes
Then it takes less than 15 minutes to fill the hemisphere

A cylinder-shaped barrel has a diameter of 8 feet and a height of 7 feet. If the barrel is empty, which is closest to the minimum amount of water needed to completely fill the barrel?
Answers
Answer: [tex]351.9\ ft^3[/tex]
Step-by-step explanation:
Given
The dimater of cylinder is [tex]d=8 \ft[/tex]
The height of the cylinder is [tex]h=7\ ft[/tex]
To fill the barrel, it must be filled with a volume equal to its volume i.e.
[tex]\Rightarrow V=\pi r^2h\\\Rightarrow V=\pi \cdot 4^2\times 7\\\Rightarrow V=112\pi\\\Rightarrow V=351.9\ ft^3[/tex]
Thus, [tex]351.9\ ft^3[/tex] of water is required to completely fill the barrel.
At a high school, 9 students volunteer for a committee. How many different 4 -person committees can be chosen?
Answers
Answer:
126 ways
Step-by-step explanation:
Total number of persons = 9
Number of commitees to be chosen = 4
Since, there is no order in the selection process, we use combination.
Choosing a committee of 4 from 9 will be :
9C4.
Recall :
nCr = n! / (n-r)!r!
9C4 = 9! / 5!4!
9C4 = (9*8*7*6) / (4*3*2*1) = 3024 / 24 = 126 ways
I've had to repost this question like 4 times because ppl put fake answers, pls put the answer if u know it and dont lie
Answers
Answer:
189.05 ft^3
Step-by-step explanation:
I think this is the right answer but I'm not 100% sure.
So first, you need to find the area of the rectangular prism. 5*5=25, and there are 5 of these rectangles (4 sides and the bottom), so the total is 125 ft^3. I don't think you would include the area of the top, as the top is not flat, and has a pyramid on it.
To find the area of the pyramid, there is a somewhat complicated and long equation that I can't write here, but you can look up the formula for the area of a square pyramid.
The area of the pyramid is around 64.05 ft^3. 125+64.05=189.0500 rounded to the nearest hundredth is 189.05 ft^3.

Determine the point of intersection between the lines with equations x+3y=5 and 3x−2y=26.
Answers
Answer:
(8,-1)
Step-by-step explanation:
The point of intersection can be found out by solving the system of equations.
x + 3y = 5
3x - 2y = 26
Multiply (1) by 3 :-
→ 3 ( x + 3y ) = 5 × 3
→ 3x + 9y = 15
Subtracting 3(1) and 2 :-
→ 3x + 9y - 3x +2y = 15 - 26
→ 11y = -11
→ y = (-1)
Put it in 1 :-
→ x -3 = 5
→ x = 3 + 5
→ x = 8
Hence the point of intersection is (8,-1)The 44 members of the glee club are trying to raise at least $6,000 so they can compete in the state championship. They already have $1,210. What inequality can you enter to find the amount each member must raise, on average, to meet the goal?.

A. The representatives of the company were male.
B. The representatives of the company only gave the survey to a select group, as opposed to a wider, more representative sample.
C. The survey questions were biased toward the congressperson's opponent.
D. The mall was outside the congressperson's local area.

Carlos bought 6.5 pounds of bananas for $5.20. What is the price per pound of the bananas that Carlos bought?
What quantity of bananas would one dollar buy?
Answers
Answer:
Quantity of banana purchase in $1 = 0.8 pound
Step-by-step explanation:
Given:
Cost of 6.5 pound of banana = $5.2
Find:
Price of one pound banana
Quantity of banana purchase in $1
Computation:
Price of one pound banana = 6.5 / 5.2
Price of one pound banana = $1.25
Cost of one pound banana is $1.25
Quantity of banana purchase in $1 = 1 pound / 1.25 dollar
Quantity of banana purchase in $1 = 0.8 pound

A charter bus service charges a flat fee of $150, plus $3.50 per mile (one way distance) for a bus. If the band paid exactly $2050 for TWO buses, how far did the band travel?
Answers
Answer:
Number of miles= 250
Step-by-step explanation:
Giving the following information:
Fixed cost= $150
Unitary cost per mile= $3.5
Total cost= $2,050
First, we will establish the total cost formula for ONE bus:
Total cost= 150 + 3.5x
x= number of miles
For two buses:
Total cost= 150*2 + (3.5*2)x
Total cost= 300 + 7x
Replacing the total cost information:
2,050= 300 + 7x
1,750/7 = x
250 =
Number of miles= 250

Which is greater |-2| or-2
Answers
To Find :
Which is the greater |-2| or -2 .
Solution :
Value of |x| for any value of x ( real number ) is always positive .
[tex]|x| = \left \{ {x , \ for \ x >= 0 \atop { -x, \ for \ x < 0 }} \right.[/tex]
So, |-2| = 2 > -2
Therefore, the value of |-2| is greater than -2 .
Hence, this is the required solution.
