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
D) (a + 1, b + m)
EXPLANATION
The given line passes through (a,b) and has slope m.
The equation is:
When x=a+1, we obtain
This
Therefore,(a + 1, b + m) must also lie on this line.
The correct answer is D.
Answer:
Step-by-step explanation:
Start off by explaining that u know this(don't use these exact word though :A composite number is a positive integer that can be formed by multiplying two smaller positive integers Equivalently. A prime number is a natural number greater than 1 that is not a product of two smaller natural numbers.... I couldn't really see the whole page so this is what i could get for u.... Good luck
Answer:
Step 1 Multiply both sides of the equation by Five-halves
Step-by-step explanation:
First mistake:
Step 1 Multiply both sides of the equation by Five-halves
Correct First step:
Should have subtracted 4p from both sides
So just you need to rationalize the denominator so multiple top and bottom by conjugate so by sqrt6 +sqrt3
8 8(sqrt6 +sqrt3) 8(sqrt6 +sqrt3)
----------------- = ------------------------------------- = ----------------------- =
sqrt6 - sqrt3 (sqrt6 -sqrt3)(sqrt6 +sqrt3) 6 -3
8(sqrt6 +sqrt3)
= -----------------------
3
hope this will help you
