Answers

Answer 1

Answer: 2/7*15
divide/multiply from left to right...
2/7*15=30/7
then simplify...
4 2/7

i hope that helped...

Answer 2

Answer: The answer may be simplify into 4 2/7.
You do this because the answer was 30/7
30÷7= 4 2/7

What is 10 divided by 11,4660

Answers

the answer is 11466 you basically just take out the 0 at the end and you divide 114660/10

That would be: 0.00087214372

If you meant:
114,660/10=

In a water treatment plant, water passes through a cone-shaped filter with a height of 4 m and a diameter of 9 m. The water flows from the filter into a cylinder below it. One full cone-shaped filter fills one-fifth of the cylinder.What are the dimensions of the cylinder? Use 3.14 to approximate pi.

A.
h = 3 m; r = 3 m

B.
h = 4.23 m; r = 5 m

C.
h = 15 m; r = 6 m

D.
h = 33.75 m; r = 2 m

Answers

so volume of a cone=1/3 times (area of base) times height

area of base=circle so
1/3 times pi times radius^2 times height

height=4
diameter=2radius
diameter/2=radius
9/2=4.5=radius

height=4
radius=4.5
aprox pi at 3.14
1/3 times (3.14 times 4.5^2) times 4=84.78
that's the volume of the cone

volume of cone=1/5 of cylinder

84.78=1/5cylinder
multiply both sdies by 5
423.9=volume of cylinder

volume of cylinder=height times area of base
area of base=3.14 times r^2
v=h3.14r^2
423.9=3.14hr^2
divide both sdies by 3.14
135=hr^2
sincewe are not given the specific ratio of height to radius or such to thecone to the cylinder, we must use trial and error to elimninate wrongchoices

135=hr^2
let's try A

A
135=3(3^3)
135=3(9)
135=27
false
A is wrong

B
4.23=h 5=r
135=4.23 times 5^2
135=4.23 times 25
135=105.75
false
B is wrong

C
h=15 r=6
135=15 times 6^2
135=15 times 36
135=540
false
C is wrong

D
33.75=h 2=r
135=33.75 times 2^2
135=33.75 times 4
135=135

the answer is D since it fitst the dimentions

$(9/2*9/2*4* \pi )/(3)$
= $(81*3.14 )/(3)$
=27*3.14 (the cone's v)
so multiply 5 to the v = 135*3.14 (cylinder's v)
A:3*3*3*3.14=27*3.14 X
B:5*5*4.23*3.14=105.75*3.14 X
C:6*6*15*3.14=540*3.14 X
D:2*2*33.75*3.14=135*3.14 O

Is 351,800 bigger than 605,908

Answers

Hey there! Let me help you out!

No, this is not true. The answer to your question is: 351800<605908. This means that 605908 is bigger than 351800. To find this out, count how many digits there are in both the numbers. The number with more digits is bigger than the other number. If both the numbers have the same number of digits, then see the starting number of each number and so forth, if they are the same. For example, for this question, count how many numbers there are in each number. They both have 6 numbers so u can't make out anything from that. Next see the starting number for each of them. In 351800, the starting number is 3. In 605908, the starting number is 6. Since 6 is larger than three, 605908 is bigger than 351,800.
