The radius of the large sphere is double the radius of thesmall sphere.
How many times is the volume of the large sphere than the
small sphere?
2
VX
O 4
O 6
O 8
Answers
Answer:
4 times as great
Step-by-step explanation:
Compute the two different volumes and then compare them.
Smaller sphere: V = (4/3) · π ·r²
Larger sphere: V = (4/3) · π · (2r)² = (4/3) · π · 4 · r²
Comparing these, one sees immediately that the volume of the larger sphere is 4 times as great as that of the smaller sphere.

or as separate equations:
y=1/2
X=4y+2
Explanation:
If we solve your system by elimination:
x−4y=2;4x−16y=8 -->
Multiply the first equation by -4,and multiply the second equation by 1.
−4(x−4y=2)
1(4x−16y=8)
Becomes:
−4x+16y=−8
4x−16y=8
Add these equations to eliminate x:
0=0

x = 7.5
Step-by-step explanation:
take 20 degree as reference angle
using cos rule
cos 20 = adjacent / hypotenuse
0.93 = 7/x
x = 7/0.93
x = 7.5

Answer: 9
Step-by-step explanation: The reason that students get intimidated
by word problems is they try to look at all the information at once.
The best way to approach a word problem
is to break it down sentence by sentence.
In this problem, let's look at the first part of the sentence.
We know that six less than three times a number is 21.
Let's call the number x.
So we know that six less than three times a number means 3x - 6.
A common mistake would be for students to put 6 - 3x.
However, the word "less than" switches the order around.
So we know that six less than three times a number is 21.
So we can write this as 3x - 6 = 21.
Now we have an equation and we can solve for x.
First add 6 to both sides to get 3x = 27.
Now divide both sides by 3 to get x = 9.
So our answer to this word problem is 9.
