Find the scale factor that was used in the dilation shown.
Answers
The scale factor that was used in the dilation could be 1.5 units.
What is scale factor?Suppose a figure (pre image) is dilated (dilated image) by scale factor of k. So, if a side of the figure is of length L units, and that of its similar figure is of M units, then:
L = k × M
where 'k' will be called as scale factor.
The quantities that are squares or multiple of linear things twice grow by square of scale factor.
So area of first figure = k² × area of second figure
Similarly,
The Volume of first figure = k³ × volume of second figure.
Since the scaling is done by product of some constant, that constant is called scale factor.
Then we have:
K = 4/6
K = 2/3
K = 1.5 units.
Thus, scale factor is the ratio of the new measurement to the old measurement therefore, the scale factor that was used in the dilation could be 1.5 units.

The tables show the amount earned by James and Paco working at the same store.
What two equations can represent James and Paco's hourly wages, where h is the number of hours worked and d is the amount of money earned?
Compare the equations to determine if there is any difference between what James and Paco make each hour.
Answers
Answer:
Step-by-step explanation:
In order to determine if James and Paco earn different amounts of money per hour, you must find how much money they make in one hour.
James:
James makes $35.40 in 3 hours. So, in 1 hour, he would make 35.40/3 = 11.8.
James makes $11.80 an hour.
Therefore, his equation would be d = 11.8h
Paco:
Paco makes $24.00 in 2 hours. So, in 1 hour, he would make 24/2 = 12.
Paco makes $12.00 an hour.
Therefore, his equation would be d = 12h
Hence, Paco and James make different amounts of money. Paco makes 20 cents, or $0.20, more than James.
Answer:
d(James) = 11.8h
d(Paco) = 12h
Paco makes $0.20/h more than James
Step-by-step explanation:
equation: y = ax + b
James:
d(Amount of money earned) = ah(number of hours worked) + b
If James worked 3 hours: 3a + b = 35.4
If James worked 5 hours: 5a + b = 59
If
3a + b = 35.4
b = 35.4 - 3a
Then
5a + b = 59
5a + 35.4 - 3a = 59
2a = 59 - 35.4
2a = 23.6
a = 23.6/2
a = 11.8
If a = 11.8, then
3a + b = 35.4
3(11.8) + b = 35.4
35.4 + b = 35.4
b = 0
If a = 11.8 and b = 0
d(Amount of money earned) = ah(number of hours worked) + b
d = 11.8h
Each hour James works, he makes $11.8
Paco:
d(Amount of money earned) = ah(number of hours worked) + b
If Paco worked 2 hours: 2a + b = 24
If Paco worked 4 hours: 4a + b = 48
If
2a + b = 24
b = 24 - 2a
Then
4a + b = 48
4a + 24 - 2a = 48
2a = 48 - 24
2a = 24
a = 24/2
a = 12
If a = 12, then
2a + b = 24
2(12) + b = 24
24 + b = 24
b = 24 - 24
b = 0
If a = 12 and b = 0
d(Amount of money earned) = ah(number of hours worked) + b
d = 12h
Each hour Paco works, he makes $12

You call your teacher and find out that the second part of the note should have said “sell four hot dogs and two bags of chips for $10.” What does that do for your system of equations now? With this new information, how much should each item cost? Again, show all of your work.
Answers
Answer:
h = $4 a hotdog
c = $2 bag of chips
Step-by-step explanation:
3h + c = 14
2h + c = 10
3h + c = 14
-2h - c = -10
h = $4 a hotdog
2(4) + c = 10
8 + c = 10
c = $2 bag of chips
Answer:
h = $4 a hotdog
c = $2 bag of chips
Step-by-step explanation
3h + c = 14
2h + c = 10
3h + c = 14
-2h - c = -10
h = $4 a hotdog
2(4) + c = 10
8 + c = 10
c = $2 bag of chips

Answers
Answer:
[tex]3\frac{3}{4}[/tex]
Step-by-step explanation:
We have two mixed numbers and are asked to multiply them together.
2 1/4 * 1 2/3
First we convert the mixed numbers into improper fractions to make it easier for us. So follow the MA rule.
Multiply the whole number by the denominator and add the numerator.
2 1/4 * 1 2/3
9/4 * 5/3
Now multiply across,
[tex]\frac{9*5}{4*3}[/tex]
[tex]\frac{45}{12}[/tex]
Now we need to convert this back into a mixed number.
So how many times does 45 go into 12?
3 times, and 3 are left.
[tex]3\frac{3}{4}[/tex]
Simplify given fraction into mixed fraction is 3³/₄
Give that:

Answers
Answer:
D. x is greater than -2
Step-by-step explanation:
Ok so,
-3x + 1 < 7
First, do the opposite of +1 which is -1 so you have to subtract 1 from both sides. Which should look like this.
-3x < 6
Then you divide -3 with 6 which will give you -2. You change the inequality sign becuase you divided with a - number.
