So
if increase by 10%, that means times 1.1
sub 1.1r for r in
V=(4/3)pir³
so
nV=(4/3)pir³
nV=(4/3)pi(1.1r)³
nV=(4/3)pi1.331r³
nv=((4/3)pir³)1.331
V=(4/3)pir³
nV=(V)1.331
x times 1.331 is about a 33% increase
Answer:
y=6x
Step-by-step explanation:
Let us assume the table is the one shown in the attachment.
We can observe the following pattern from the table:
Hence in general
Therefore the equation that could have been used to create this table is
The y represents "some number," so in this case some number divided by three is the right answer
Answer:
x=2
y=2
Step-by-step explanation:
You can use the process of elimination
<em>x </em>can't be 3 because than the first question would be 9+<em>y</em>=8 which is even bigger than the answer.
So now, we try 2. <em>x=2</em>
<u><em>6+y=8</em></u> which =
<u><em>6+2=8</em></u>
So<em> y</em> must be two
Then we try it on the
Second one.
<u><em>8-6=2</em></u> which makes sense.
Hope it helps
Answer:
no solution
Step-by-step explanation:
these are the same equation.
bottom one is the top multiplied by 2
