The answer that I got was:
8y (y-3x)
because I divided everything by 8y and then just did simple math
hope this helps
Answer:
Step-by-step explanation:
Let x represent the certain number of of subscriptions in an hour that each of them would sell so that they will end up earning the same amount.
Michelle earns a base wage of $8 per hour, as well as $1 for every subscription that she sells. This means that the total cost of selling x subscriptions in an would be
x + 8
Cody gets $3 per subscription sold, in addition to a base wage of $4 per hour. This means that the total cost of selling x subscriptions in an hour would be
3x + 4
For both of them to earn the same amount,
x + 8 = 3x + 4
3x - x = 8 - 4
2x = 4
x = 4/2 = 2
They would earn the same amount when they sell 2 subscriptions.
The amount that each would earn is
2 + 8 = $10
The complete question is
<span>Four golf balls are packaged in a cylindrical container as shown below. The balls just touch the top, bottom, and sides of the cylinder. The diameter of each ball is 4cm.
1) </span><span>What is the volume of the cylinder rounded to the nearest cubic centimeter?
</span>2) <span>What is the total volume of the four balls rounded to the nearest cubic centimeter?
</span>3) <span>What percent of the volume of the container is occupied by the four balls?
</span><span>
Part 1) volume of the cylinder=pi*r</span>²*h
<span>r=4/2----> 2 cm
h=4*4----> 16 cm
</span>volume of the cylinder=pi*2²*16----> 200.96 cm³----> 201 cm³
the answer Part 1) is 201 cm³
Part 2) volume of a sphere=(4/3)*pi*r³ ( is equal to volume of one <span>golf ball)
</span>r=2 cm
volume of a sphere=(4/3)*pi*2³ ----> 33.49 cm³
so
volume of four golf ball-----> 4*33.49----> 133.97 cm³----> 134 cm³
the answer part 2) is 134 cm³
part 3)
volume of cylinder=201 cm³
volume of the four golf ball=134 cm³
so
if 201 cm³-----------> 100%
134 cm³--------> x
x=134*100/201----> x=66.67%
the answer part 3) is 66.67%
Answer:
The values are a=-6 and b=18.
Step-by-step explanation:
A Geometric sequence is given by the formula
for all , where r ≠ 0 is the common ratio and is the first term of the sequence
.
In this problem we know that m=
2, is the second term of the sequence and is the third term.
First we need to find the general form of the sequence, we can use the fourth term and the value of to find r.
We replace and in the formula , then we have
.
Therefore the general form of the sequence is for all .
To find the value of a, we replace n=2 in our formula, so
.
To find the value of b, we replace n=3 in our formula, so
.
