Answer:
Naja earns 64$ per 8 hours of work
Step-by-step explanation:
2 steps:
Step 1
Divide 5 by 40 to find how much dollars per hour
[tex]\frac{40}{5} =8[/tex]
8, so that means that Naja earns $8 per hour
Step 2
Multiply 8 by 8 to get final answer
[tex]8*8=64[/tex]
$64, so that means that Naja earns 64$ per 8 hours of work
Naja earns 64$ per 8 hours of work
Answer:
$64 for 8 hrs.
Step-by-step explanation:
There are 2 ways you could do this. The easy way is the first one.
1. Divide 40 by 5 and you get 8. 2. After you get that answer, then you have to multiply 8x8=64. So she gets $64 per hour.
Then there is the harder one. This is if they say to show your work.
1. Start by putting it in this format:
5 -- 40
6 -- 48
7 -- 56
8 -- 64
So you basically just add 8 each time to get 64.

If you get it correct I will give you an brainliest!
Answers
Answer:
[tex]23=0.50r+22[/tex]
Step-by-step explanation:
y=total amount of money
b=cost of admission
m=cost per ride
r= amount of rides
How to solve:
Step 1: Set up the equation in [tex]y=mx+b[/tex] format.
[tex]23=22+0.50r[/tex]
Step 2: Subtract 22 from both sides of the equation.
[tex]23-22=22+0.50r-22[/tex]
Step 3: Divide both sides by 0.50
[tex]\frac{1}{0.50} =\frac{0.50r}{0.50}[/tex]

B) what is the probability of having 2 girls and one boy?
C) what is the probability of having 2 boys and one girl?
D) josh has a younger brother. what is the probability that a third child will be another boy? explain.
Answers
Answer:
probability=number of favorable outcome÷total number of favorable outcome
Step-by-step explanation:
A the probability that all children are boys =3÷3 =1
same answer with the girl children
Answer:
A) 1/8 or 0.125 for three girls and three boys
B) 3/8 or 0.375 for two girls and one boy
C) 3/8 or 0.375 for two boys and one girl
D) 1/2 or 0.50, explanation provided below
Step-by-step explanation:
Part A) If a family has three children, the probability that all three children are girls can be found by first finding the probability of one child being a girl. The probability of being a girl in this case is 1/2. The probability of three girls is thus (1/2) * (1/2) * (1/2) = 1/8 or 0.125. The probability of one child being a boy is 1/2, and so rather than repeating the above steps, we can simply say that it is also 1/8 or 0.125.
Part B) For this part, it is probably easiest to list the combinations:
BBB
BBG
BGB
BGG
GBB
GBG
GGB
GGG
There are three outcomes with two girls and one boy and thus the probability is 3/8.
Part C) Looking at the combinations above, we also see that there are three outcomes with two boys and one girl, and thus the probability is 3/8.
Part D) The fact that Josh has a younger brother does not affect the probability that the third child will be a girl or boy. The probability of the third child being a boy is still 1/2.

Data Set : {8, 2, 5, 0, 1, 9, 2, 5, 2}
Arrange in ascending order : {0, 1, 2, 2, 2, 5, 5, 8, 9}
Range = Last Term - First Term = 9 - 0 = 9 is the range
Mean = sum of terms/number of terms = 34/9 = 3.777... = 3.78 is mean
Mode = the most appearing integer in the set = 2 is the mode
Median = The integer at the middle of the set = 2 is the median
======================
Range = 9Mean = 3.78Mode = 2Median = 2Mean: Add up all the numbers and divide by the amount of numbers. 8+2+0+1+9+2+5+2= 29 then divide by 9 = 3.22 therefore the mean is 3.22.
Mode: Number that appears the most frequent. There can be multiple. In this case the mode is 2.
Median: The middle number. First order from lowest to highest: 0,1,2,2,2,5,8,9. In this case the median is 2 and 2. So we simply add 2+2 which equals 4 and divide it by 2. Therefore the median is 2. Hope this helped!!

How to write fractions in simplest form?
( I give brainliest )
Answers
It's pretty easy, take the example of this fraction... [tex]\frac{2}{4}[/tex]
What you do in here is that you note down the factors of 2 and 4 over here.
Factors of 2 and 4:
2 = 1, 2
4 = 1, 2, 4
Now, you see that the GREATEST Common Factor (GCF) over here is 2.
Now that we see the GCF of 2 and 4 is 2, what you do next is, you have to divide 2 by 2 AND 4. When you do this, you will get your results. 2 = 1 and 4 = 2, now put this in the fraction form again, meaning switch 2 with 1, and 4 with 2 in the fractions... [tex]\frac{1}{2}[/tex]
So your simplified fraction is [tex]\frac{1}2}[/tex]!
Answer:
A fraction is in simplest form when the top and bottom cannot be any smaller, while still being whole numbers.
You can simplify a fraction by dividing the top and bottom by the greatest number that will divide both numbers exactly. They must stay whole numbers.

From the triangles given, ∆ DEF was dilated to ∆ ABC
The dilated triangle is = ∆ ABC
To find the scale factor uses for the dilation of the triangle, the length of the triangle AC and DF are considered.
AC from the scale= -2 -(-7)
= 7-2= 5
DF= 9-6.5
= 2.5
Therefore the scale factor = 5/2.5 = 2
And since the scale factor of dilation is 2 this means that ∆ A' B' C' can be translated to the 0.5 by 2 units.
