It’s 68, the bottom one is 5x5x2 and the top one is 3x3x2 and then add them to get 68
G=number of words on george's page
b=number of words on bill's page
c=number of words on charlie's page
george has 2 times as many as bill's age
g=2b
bills contains 50 less than charlie
b=c-50
if each person can type 70 words per minute, after 1 minute (that is an additional 70 words for each person)
the difference between twice nmber of words on bill's page and the number of words on charlie's page is 220
so
that is after increase of 70 words
2(b+70)-(c+70)=220
and
b=c-50
subsittute
2(c-50+70)-(c+70)=220
2(c+20)-c-70=220
2c+40-c-70=220
c-30=220
c=250
charlie had 250 initially
b=c-50
b=250-50
b=200
bill had words 200 initially
who cares about george

Step-by-step explanation:
The bicycle costs the owner of the store 100% of its price.
He then adds 45% of that amount to the cost of the bicycle to come up with the selling price. It is this increase of 45% that is called a 45% markup.
100% + 45% = 145%
The bicycle's selling price is 145% of what it cost the store owner.
Let the original cost be x.
145% of x = $232
1.45x = 232
x = 232/1.45
x = 160
Answer: $160
Answer:
Martha can write 3.75 essays in 15 hours. (Which is a lot for me)
Step-by-step explanation:
First, I divide 2 by 8.
2 ÷ 8 = 0.25
Next I multiply 0.25 by 15.
0.25 * 15 = 3.75
So, the answer is 3.75
Hope this helps! :)
<span>The mean is 3.25.
IT IS A NEGATIVE SKEW.
</span>
Why is it called negative skew? Because the long "tail" is on the negative side of the peak.
People sometimes say it is "skewed to the left" (the long tail is on the left hand side)
The mean is also on the left of the peak.
