1.
yes
x is number of group acts
y is number of indivual acts
2. I would eliminate x by multiplying 2nd equation by -3 then adding
12x+6y=120
<u>-12x-3y=-90 +
</u>0x+3y=30
3y=30
divide by 3
y=10
sub
4x+y=30
4x+10=30
4x=20
divide 4
x=5
each group act takes 5 mins and each individual takes 10 minutes

Answer:
The area of the base is = 5.2 cm²
Step-by-step explanation:
<em>First, we need to know the formula to calculate volume:</em>

<em>if we change to our equations to the values we know:</em>

<em>Since 3.14 is multiplying B,we can pass it to divide the volume to the left side:</em>

<em>We calculate the operation=</em>

<em>And the answer is 5.2 cm²</em>
<em>Let me know if you have any question :D</em>
Answer: 0.10
Step-by-step explanation:
Find the number in the hundredth place
9
9
and look one place to the right for the rounding digit
9
9
. Round up if this number is greater than or equal to
5
5
and round down if it is less than
5
5
.
0.10
it is 100 times greater because it is two places higher than 57,080
