ASAP (I will give brainliest for most accurate answer) move the options to the blank to complete the series of transformations that will show triangle abc - def
Answer:
1. is 2
2. is right and 10
Step-by-step explanation:
just took the test will explain if needed
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.

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.

Answer:
24 units³
Step-by-step explanation:
Formula:
Volume (V) = length (l) × width (w) × height (h)
V=3×4×2=24 units³
Answer:
the answer should be 24 units^3 because the formula for finding volume is V= lwh so we need to multiply 2 times 3 and 4 and when we do that we get an answer of 24 so a is the correct answer and have a great day.

Answer:
The length of a pencil is 4.5 inches. The length of a crayon is 2.1 inches.
Step-by-step explanation:
Let pencils be p
Let crayons be c
6 pencils and 5 crayons are 37.5 inches. This will be:
6p + 5c = 37.5 ........ equation 1
7 pencils and 6 crayons are 44.1 inches. This will be:
7p + 6c = 44.1 ........ equation 2
Multiply equation 1 by 7
Multiply equation 2 by 6
42p + 35c = 262.5 (3)
42p + 36c = 264.6 (4)
Subtract 4 from 3
c = 2.1
Plug the value of c into equation 1
From equation 1
6p + 5c = 37.5
6p + 5(2.1) = 37.5
6p + 10.5 = 37.5
6p = 37.5- 10.5
6p = 27
p = 27/6
p = 4.5

PLS HELP!! ITS PROBABILITY!!!
A) if a family has three children, what is the probability that all three children are girls? all three children are boys?
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.
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.

It costs $22 to enter an amusement park and $0.50 to ride a ride. You have $23. Write an equation that represents the number r of rides you can ride.
If you get it correct I will give you an brainliest!
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]
Step 4: You are left with your answer.
[tex]r=2[/tex]

19200=480x
x=40

How to write fractions in simplest form?
( I give brainliest )
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.
