Percent means per 100, so 45% would be 45 out of 100, which written as a fraction would be 45/100
The answer would be C.

Answer:
2 pt + 1c
Step-by-step explanation:
There are 2 cups in a pint. So, 2c = p, dividing 2 from both sides, we get
c = (1/2)p
Replace c with 1/2 p in the equation
5 pt - (2pt + (1/2)p)
= 5pt - 2pi - (1/2)p
= 3pt - (1/2)p
= 2pt + (1/2)p
Replace back (1/2)p for c
2pt + (1/2)p =
2 pt + 1c

9. Melissa is making a set of 5 bulletin boards for her friends. She plans to decorate the bulletin boards with a strip of ribbon across each diagonal. If the bulletin boards are 12 in by 24 in, about how many total inches of ribbon will she use for all 5 boards? show work
Answer:
Melissa will need 7200 square inches of ribbon to make the 5 bulletin boards.
Step-by-step explanation:
Since Melissa is making 5 bulletin boards for her friends, and each one measures 12 inches wide by 24 inches long, to determine the number of inches that Melissa should use in total, the following calculation must be performed:
12 x 5 + 24 x 5 = X
60 x 120 = X
7,200 = X
So, Melissa will need 7200 square inches of ribbon to make the 5 bulletin boards.

Answer:
Ok so I’m stuck with this question too But I got the top part.
p=1/6
q=2/6
r=3/6
s=3/6
A) The probabilities placed at P, Q, R and S on the tree diagram are;
P = 1/6; Q = 1/3; R = 1/4; S = 1/4
B) The probabilities of her winning or losing is;
Probability that she will win = 5/12
Probability that she will lose = 7/12
A) From the given tree diagram, we can see that;At point P; Only 1 is rolled.
Since there are 6 possible numbers, then Probability at P = 1/6
At point Q; either 2 or 3 can be rolled.
Since there are 6 possible numbers, then Probability at Q = 2/6 = 1/3
At point R; 4,5, or 6 can be rolled on first roll.
Thus, Probability on first roll = 3/6
At R on second roll if she gets even, probability on second roll = 3/6
At S on second roll if she gets odd, probability on second roll = 3/6
Thus;
Overall probability at R = 3/6 × 3/6 = 1/4
Overall probability at S = 3/6 × 3/6 = 1/4
B) Probability that she will win are the probabilities at P and R.Thus, probability that she will win = 1/6 + 1/4 = 5/12
Probability that she will lose are the probabilities at Q and S.
Probability that she will lose = 1/3 + 1/4 = 7/12

There are 5 bubble grid questions and 15 multiple choice questions.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Let,
Multiple choice questions denoted by M
Bubble grid questions are denoted by B
A 20-question math test is worth 100 points.
M+B=20..(1)
Multiple choice questions worth 4 points each. Bubble grid questions are worth 8 points each.
4M+8B=100..(2)
From equation 1,
M=20-B
4(20-B)+8B=100
80-4B+8B=100
80+4B=100
Subtract 80 from both sides
4B=20
Divide both sides by 4
B=5
Now plug in B value in equation 1.
M+5=20
Subtract 5 from both sides
M=15
Hence, there are 5 bubble grid questions and 15 multiple choice questions.

Dan rolls 2 fair dice and adds the results from each. Work out the probability of getting a total less than 3.
Answer:
1 / 36
Step-by-step explanation:
A roll of 2 fair dice :
Total number of possible outcomes = n² ; n = number of faces in a dice = 6² = 36
Probability = required outcome / Total possible outcomes
Required outcome = total less than 3 = 1 (from sample space provided)
Hence,
P(total less than 3) = 1/36
