a conical vessels with base radius 5 cm and height 24cm is full of water this water is emptied into a cylindrical vessel of base radius 10cm find the height to which the water will rise in the cylindrical vessel
please help me
Answer:
[tex]2\ cm[/tex]
Step-by-step explanation:
[tex]We\ are\ given\ that,\\Radius\ of\ the\ conical\ vessel=5\ cm\\Height\ of\ the\ conical\ vessel=24\ cm\\Hence,\\As\ we\ know\ that,\\Volume\ of\ a\ cone=\frac{1}{3}\pi r^2h\\Hence,\\The\ volume\ of\ the\ conical\ vessel=\frac{1}{3}\pi (5)^224= \frac{1}{3}\pi 25*24=200\pi \\Hence,\\The\ volume\ of\ the\ conical\ vessel=The\ amount\ of\ water\ filled\ in\ it\\Hence,\\The\ amount\ of\ water\ filled\ in\ the\ conical\ vessel=200\pi\\Lets\ consider\ the\ cylindrical\ vessel:\\Volume\ of\ a\ cylinder=\pi r^2h[/tex]
[tex]As\ we\ are\ not\ said\ that\ the\ cylindrical\ vessel\ was\ empty,\ let\ its\ initial\\ height\ be\ h_1\\Radius\ of\ the\ Cylindrical\ vessel=10\ cm\\Initial\ height\ of\ the\ cylindrical\ vessel=h_1\\Initial\ volume\ of\ the\ cylindrical\ vessel=\pi *10^2*h_1=100h_1\pi \\Initial\ amount\ of\ water\ in\ the\ cylindrical\ vessel=100h_1\pi \\Hence,\\Final\ amount\ of\ water\ in\ the\ cylindrical\ vessel=Final\ amount\ of\ water\\ in\ the\ cylindrical\ vessel +Amount\ of\ water\ in\ conical\ vessel[/tex]
[tex]Hence,\\Final\ amount\ of\ water\ in\ the\ cylindrical\ vessel=100h_1\pi +200\pi \\Now,\\Let\ the\ final\ height\ be\ h_2\\Hence,\\Final\ amount\ of\ water\ in\ the\ cylindrical\ vessel=\pi *10^2*h_2=100h_2\pi \\Hence,\\100h_2\pi =100h_1\pi +200\pi \\Hence,\\100h_2=100h_1+200\\100h_2-100h_1=200\\100(h_2-h_1)=200\\h_2-h_1=2\\Hence,\\As\ the\ rise\ in\ level\ is\ the\ difference\ between\ the\ initial\ and\ final\\ heights:\\The\ rise\ in\ level\ of\ water=2\ cm[/tex]

Crystal earns $8.00 per hour mowing lawns.How much does Crystal earn is she works 3 hours and 30 minutes?
Answer:
she can earns $28
Step-by-step explanation:
Answer:
$24.40
Step-by-step explanation:
if she gets $8 per hour than in 3 hours she would have earned $24 cause 8*3=24.
since she works for 3h and 30 min to find the 30 min we have to divide 8 by 2 becasue 30 min is halve an hour so by doing this you get 8/2=4

f(x) = 2 If 2 < x ≤ 4
x + 3 If 4 < x < 8
2x If x ≥ 8
1). f(x) = 2 will be a straight line parallel to x-axis for 2 < x ≤ 4
2). f(x) = x + 3 is a straight line with input output points in the interval 4 < x < 8
x 4 5 6 7 8
f(x) Not defined 8 9 10 Not defined
3). f(x) = 2x
x 8 9 10 11
f(x) 16 18 20 22
By using these points on a graphing calculator we can graph the piecewise function as attached.

What is the relationship between the ratios?
10/24 and 5/12 please help i give 10 points its middle school mathematics i don't know why it says high school
Given:
[tex]\dfrac{10}{24}[/tex] and [tex]\dfrac{5}{12}[/tex].
To find:
The relationship between the ratios.
Solution:
We have, two ratios in the fraction form.
[tex]\dfrac{10}{24}[/tex] and [tex]\dfrac{5}{12}[/tex]
First ratio = [tex]\dfrac{10}{24}[/tex]
= [tex]\dfrac{2\times 5}{2\times 12}[/tex]
=[tex]\dfrac{5}{12}[/tex] (Cancel out the common factors)
First ratio = Second ratio
Since, the both ratios are equal to each other, therefore, the given ratios are equivalent ratios.

Answer:
68.78° or 0.6 radStep-by-step explanation:
Use the formula:
degrees/360° = L/circumferenceor radians/π = L/circumferenceAs per given:
l = 12 feet, r = 10 feet
degrees = 360°*12/(2*3.14*10) = 68.78° radians = π rad *12/(2π*10) = 0.6 radGlen mixes red bricks with yellow bricks when building sides of a brick house.

Answer:f(x) in order from left to right= -20, 5, 10, 15, 30 i.) -.06 ii.)-40
Step-by-step explanation: f(x) is the answer of 5 times whatever x is, so when it’s telling you what x is all you have to is multiply it by the number next to x which in this case is 5. after doing that you get the answers above. for i.) it’s telling you the answer which is -3, so you divide that by 5 getting -.06. In ii.) it gives you x which is -8 so you plug that in giving you -40.

CD = (6 cm)²/(9.6 cm) = (36/9.6) cm
CD = 3.75 cm
8. It takes Juan 40 minutes to walk 2.5 miles to the park. At this rate, how many minutes
should it take him to walk 4 miles? HELPP PLZ!!!
Answer:
64 minutes
Step-by-step explanation:
40 divided by 2.5 = 16
4 times 16 = 64 minutes
It will take 64 minutes to walk 4 miles.
What is a Ratio?A ratio indicates the number of times one number contains another.
Given that, Juan walks 2.5 miles in 40 minutes.
2.5 miles = 40 minutes
1 mile = 40/2.5 minutes
4 miles= (40/2.5)4 minutes
4 miles = 64 minutes.
Hence, It will take 64 minutes to walk 4 miles.
