Answer:
45 girls
Step-by-step explanation:
If 60% of the class is girls then 40% of the class is boys.
30 boys are in the class, meaning that 40% of the class comprises those 30 boys
First, we need the total number of class members: 30/x = 40/100 -> 40x=3000 -> x=3000/40 -> x=75
Now that we know the total class members, at 75, we can calculate the number of girls in the class. You can do this:
0.6*75=45
or
60/100=x/75 and solve for x
Answer:

Step-by-step explanation:

If any number or fraction is divided by a fraction or number, we multiply the dividend by the reciprocal of the divisor. Reciprocal of any number or fraction can be obtained by interchanging the position of numerator and denominator

To multiply one fraction by another , multiply the numerators for the numerator and multiply the denominator for its denominator.

Answer:
(x + 13, y + 7)
Step-by-step explanation:
Hello there!
In order to find what the translation rule is, we need to find how much it move to the right/left and up/down
In this case, the line segment VW moved up 7 and to the right by 13
We can get this by checking how far apart the points are
I checked how far apart V and V prime
(V prime is the green V. When a point is primed, its just saying that the point has gone through translation, rotation, dilation, or reflection)
V is 13 units to the left of V prime and 7 units below V prime
This means that, to go from line VW to line V prime W prime, you need to shift the line up 7 units and to the right 13 units
So, the translation rule is (x + 13, y + 7)
*If you don't understand, tell me in the comments, I will try to explain further to your understanding. Thank you, and have a great rest of your day :)*
First, let's write an equation for the situation.
Jim's weight is 30 pounds less than Tom's, so his weight is:
n - 30
If Tom's and Jim's weights add to 210:
n + (n - 30) = 210
Solve for n:
2n - 30 = 210
2n = 240
n = 120
Tom weighs 120 pounds.
Answer:
10
Step-by-step explanation: because if you get 45$ for breaking 1 and lose 20$ for paying for it you will just get 25$ for breaking each board
