Sixty percent of a class is girls. If here are 18 girls in a class, then how many total students are there?
Answer:
30 students
Step-by-step explanation: If 60% is 18, then 10% wold be 3. And we know that 10% multiplied by 10 is 100%. Therefore 3 multiplied by 10 should be euqal o the total amount of students. And since 10% times 3 is 30, there are 30 students in total.
Answer:
30 students
Step-by-step explanation:
We can do this question using direct proportion.
"If 18 girls represent 60%, how many students represent 100%?"
18/60=x100
x=18×100/60
30 students altogether.

"What is the general process for solving an equation with one variable?"...
Typically when solving an equation with one variable, your objective is to isolate the variable on one side of the equation. This can be done adding/subtracting number to cancel them out on one side. You can also multiply/divide coefficients in order to isolate a variable.
Example:
2x+4=64
Add -4 to both sides to isolate the variable.
(2x+4)+(-4)=(64)+(-4)
Simplify.
2x=60
Divide both sides by 2 to isolate the variable on one side.
(2x)/2=(60)/2
x=30

Answer:
A is graph 3
B is graph 1
C is graph 2
Step-by-step explanation:
A is graph 3 because it’s says that she begins with at least a total of 80 os the y should not start at 0, instead it should, start at 80 but every time she gets a question wrong the graph keeps going down.
B is graph 2 because it States that Heath has 10 pennies to begin with so the y isnt 0 but 10 and every time she doubles it the graph only goes up.
C is graph 1 because it states that to Exeter a school fair it’s 5 bucks but each ticket cost 50 cents so it starts at 5 then keeps going up.
(I’m 100% sure of A but I’m not really sure about B and C but this is my best guess)

Suppose you are given four statements about a number: a) It is the number 9. b) It is a prime number. c) It is an even number. d) The number is divisible by 15. Only two statements out of four are true. What is the least possible positive value for the unknown number?
Answer:
30
Step-by-step explanation:
as 9 isnt divisible by 15 or even, it cant be true. it cant be a prime number and even so thats not true either. the number must be 30 because it is divisible by 15 and even and the least possible value.
A farmer can buy two types of plant food, mix A and mix B. Each cubic yard of mix A contains 35 pounds of phosphoric acid, 15 pounds of nitrogen, and 16 pounds of potash. Each cubic yard of mix B contains 14 pounds of phosphoric acid, 18 pounds of nitrogen, and 64 pounds of potash. The minimum monthly requirements are 840 pounds of phosphoric acid, 540 pounds of nitrogen, and 768 pounds of potash. If x is the number of cubic yards of mix A used and y is the number of cubic yards of mix B used, write a system of linear inequalities that indicates appropriate restraints on x and y. Find the set of feasible solutions graphically for the amounts of mix A and mix B that can be used.
Answer:
The answer is below
Step-by-step explanation:
Given that the minimum monthly requirements are 840 pounds of phosphoric acid, hence:
35 pounds of phosphoric acid mix A + 14 pounds of phosphoric acid mix B ≥ 840 pounds of phosphoric acid
35x + 14y ≥ 840
The minimum monthly requirements are 540 pounds of nitrogen, hence:
15 pounds of nitrogen mix A + 18 pounds of nitrogen mix B ≥ 540 pounds of nitrogen
15x + 18y ≥ 540
The minimum monthly requirements are 768 pounds of potash, hence:
16 pounds of potash mix A + 64 pounds of potash mix B ≥ 768 pounds of potash
16x + 64y ≥ 768
Also, x ≥ 0 and y ≥0.
Therefore the equations are:
35x + 14y ≥ 840
15x + 18y ≥ 540
16x + 64y ≥ 768
x ≥ 0 and y ≥ 0

Sara's boss informed her she is getting a 5% raise. She currently makes $22 per hour. What is her new hourly wage?
Answer:
Her new hourly wage will be $23.10.
Step-by-step explanation:
First, let's find out how much her raise is in dollars.
0.05 x 22 = 1.10
Then, let's add that to her current wage.
1.10 + 22.00 = $23. 10
The amount of money of her new hourly wage will be $23.1 per hour.
What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
Sara's boss informed her she is getting a 5% raise. She currently makes $22 per hour.
Let 'y' be the new hourly wage. Then the equation is given as,
0.05 = (x - $22) / $22
x - $22 = $1.1
x = $23.1 per hour
The amount of money of her new hourly wage will be $23.1 per hour.

A bag containing 15 ounces of mixed nuts contains 40% cashews. Liam adds 45 ounces of mixed nuts containing 60% cashews in the bag. What percent of the mixed nuts in the bag is cashews?
A.27
B.33
C.45
D.55
Answer:
The answer is D. 55%
40% cashews in 15 ounces = 40/100 × 15 = 600/100 = 6 ounces of cashew
60% cashew in 45 ounces = 60/100 × 45 = 2700/100 = 27 ounce of cashew
total weight of the mixed nuts = 15 + 45 = 60 ounces
total weight of cashew = 27 + 6 = 33 ounces
% of cashew in the 60 ounce bag = 33/60 × 100 = 3300/60 = 55%
