The 8th grade students at two middle schools are raising money by washing cars.
Eastern School has already raised $625 and charges $4.50 per car. West School
charges $6.00 per car and has already raised $475. Which of the following equations
can be used to find c, the number of cars each school needs to wash so that the total
amount raised is the same for both schools?
A. 625c +4.5 = 475c + 6
B. 4.50 +625 = 6c +475
C. 625c +6=4750 +4.5
D. 4,5c 1475 = 6c 4625
Answers
Answer:
B is the only answer
Step-by-step explanation:
all other answers plug the amount of money (c) onto the whole amount that they've made, multplying in this manner would give a bigger number. B is the only excusable equation since plugging the (c) onto the West school would bring the total closer to the final amount.

Step-by-step explanation:
cos rule:
a²=b²+c²-2xaxbxcosA
rearrange:
cosA=(b²+c²-a²)÷(2xaxb)
solve:
cosx=(8²+22²-16²)÷(2x8x22)
cosx=(64+484-256)÷352
cosx=292÷352
cosx=0.830

Mary is making a birthday cake to surprise her mom. She needs 3 1/2 cups of flour, but she only has 1/3 cup. How much more flour does she need?
Answers
Answer:
3 1/6 cups more
Step-by-step explanation:
Answer:
3 1/2 = 7/2 (write as a mixed number)
7/2 - 1/3 = ?( you need more flour, so subtract what you have from what you need. to subtract you need to find the least common denominator)
21/6 - 2/6
19/6 cups of flour is what you need.
or 3 1/6 cup if it needs to be converted back into a mixed fraction

Suppose that 6 out of the 19 doctors in a small hospital are General Practitioners, 9 out of the 19 are under the age of 45, and 3 are both General Practitioners and under the age of 45. What is the probability that you are randomly assigned a General Practitioner or a doctor under the age of 45
Answers
Answer:
12/19
Step-by-step explanation:
We have these events
A = Doctors are general practitioners
B = doctors are under the age of 45
P(A) = 6/19
P(B) = 9/19
P(A n B) = 3/19
Then the probability of being assigned a general practitioner under age 45
P(AuB)
= P(A) + P(B) - P(A n B)
= 6/19 + 9/19 - 3/19
= 12/19
So 12/19 is the probability of getting a general practitioner under age 45.

Solve the following equation algebraically: 5x2 = 60
a. x~ +3 46
b. x~3.46
c. x = 12
d. X = +12
Answers
Answer:
x = 3.46
Step-by-step explanation:
In this question, you have to solve the equation.
Solve:
5x² = 60
Divide both sides by 5.
x² = 12
In order to eliminate the exponent, you would square root both sides.
√x² = √12
x = √12
√12 = 3.4641..
x = 3.46
Your final answer would be x = 3.46
