Nick recently started a landscaping company. He began with 3 clients. Thanks to word-of-mouth referrals, his clients double each

pashok25 [27]

If Nick began with three clients, you would do basic math to get here.

January / 3
February / 3•2 = 6
March / 6•2 = 12
April / 12•2 = 24
May / 24•2 = 48
June / 48•2 = 96
July / 96•2 = 192
August / 192•2 = 384
September / 384•2 = 768
October / 768•2 = 1,536
November / 1,536•2 = 3,072
December / 3,072•2 = 6,144

Nick would start with 3 clients and end with 6,144 clients.

Describe which strategy you would use to divide 48 by 8

Whitepunk [10]

You can repeat 8 till you get to 48 and count how many 8's you needed to get there.

This is one of the many strategys but there are better ones.

The median of a set of three numbers is x. there at least three numbers in the set. Write an algebraic expression, in terms of x

LUCKY_DIMON [66]

The median of a set of three numbers is x. there at least three numbers in the set. Write an algebraic expression, in terms of x, to represent the median of the new set of numbers obtained by
a] adding 1/8 to every number in the set
Let the numbers be w,x,y
adding 1/8 to the number we get:
(w+1/8),(x+1/8),(y+1/8)
the new median will be:
(x+1/8)

b. subtracting 9 1/4 from every number in the set
Given our data set is w,x,y
adding 9 1/4 to each number we get:
(w+9 1/4),(x+9 1/4), (y+9 1/4)
thus the new median is:
(x+9 1/4)

c]multiplying -5.8 to every number in the set and then adding 3 to the resulting numbers
Multiplying each number by -5.8 we get:
(-5.8w),(-5.8x),(-5.8y)
adding 3 to these numbers we get:
(-5.8w+3),(-5.8x+3),(-5.8y+3)
thus the new median is:
(-5.8x+3)

d]dividing every number in the set by 0.5 and then subtracting 1 from the resulting numbers
dividing each number in our set by 0.5 we get:
(w/0.5),(x/0.5),(y/0.5)
this will give us:
(2w),(2x),(2y)
then subtracting 1 from the above we get:
(2w-1),(2x-1),(2y-1)
thus the median will be:
(2x-1)

e. adding 7.2 to the greatest number in the set
from our set:
w.x.y
the greatest number is y, then adding 7.2 to the greatest numbers gives us:
y+7.2
thus new series is:
w,x,y+7.2
thus the median is:
x
Conclusion
The median doesn't change

f. subtracting 4.2 from the least number in the set
from our set w,x,y; subtracting 4.2 from the least number gives us:
w-4.2
the new set is:
w-4.2, x, y
thus the new median is x
Conclusion
The median doesn't change

An amusement park sold a total of 86 tickets. 34 of the tickets were child tickets, and the rest were adult tickets. What is the

xxMikexx [17]

Think of a ratio as a fraction. A ratio is basically another form of a fraction, and vice versa.

There are three ways that a ratio can be shown:

1:4

1 to 4
$\frac{1}{4}$

Let's look at the problem.

We know that:

There were 86 tickets sold in total.

34 of the tickets sold were child tickets.

Let's look at the question now.

It is asking for the ratio of the number of adult tickets to the total number of tickets.

We already know that there are 86 tickets in total.

We can simplify the question.

Now the question looks like: What is the ratio of the number of adult tickets to 86 tickets?

Since ratio doesn't require units, we can change the question to: What is the ratio of the number of adult tickets to 86?

Now, we don't know the number of adult tickets...yet.

We do know, however, that 34 of the tickets sold were child tickets, and that 86 tickets were sold in total.

To find out the number of adult tickets sold, we can simply subtract 86 (total amount of tickets sold), by 34 (# of child tickets sold).

86 - 34 = 52

Now, we know that 52 adult tickets were sold, and that 86 tickets were sold in total.

All that's left to do is to put the information together.

The question is: What is the ratio of the number of adult tickets to 86?

Or

What is the ratio of 52 (# of adult tickets sold) to 86?

Now, remember that ratio can be written in 3 ways. One of the ways is to use "to" between the two numbers being compared.

The problem is basically stating: 52 to 86

The ratio of the number of adult tickets to the total number of tickets is 52 to 86, or 52:86, or
$\frac{52}{86}$
Wait. We can simplify the ratio. Remember that fractions can be simplified?

Both 52 and 86's GCF...

{Greatest Common Factor (the number by which two quantities (numbers) can be divided equally) }

...is two.

So,
$\frac{52}{86} = \frac{26}{43}$
The final answer would be: The ratio of the number of adult tickets to the total number of tickets is 26 to 43, 26:43, or
$\frac{26}{43}$
.

1.) The Carter family owns a total of 16 fishes. Peter owns 8 fishes, and his sister, Emma, owns the rest. What is the ratio of the number of fishes that Emma owns to the total number of fishes owned by the Carter family in its simplest form?

2.) Sarah and her friends ordered a small pizza with 12 slices. One of Sarah's friends, Marco, ate 5 slices, while the others ate the rest. What is the ratio of the number of slices that Marco ate to the total number of slices eaten by Sarah and her friends in its simplest form?
