Turn the following fraction into a PERCENT: 15/60
A company that manufactures dishwashers is testing their latest product to see how long it takes to cool down once a cycle is complete. The function, f(x) = 360 - 15x, represents the cooling cycle, where x is equal to the number of minutes and f(x) is equal to the temperature of the dishwasher after x minutes.
Step-by-step explanation:
Given that the function for the temperature of the dishwasher is
f(x) = 360 - 15x
We are told that x represents the number of minutes it takes to cool down.
with a given/known value of x we can predict the temperature of the dishwasher.
Say x=12 minutes, we can tell what the temperature will be after 12 minutes
by plugin in the value of x=12 in the expressions for the temperature
f(x) = 360 - 15(12)
f(x) = 360 - 180
f(x) = 180
The temperature after 12 minutes will be 180°

- The value of y varies directly with x. If x= 4,
then y= 32. What is the value of x when y= 176?
Answer: Wouldn't that make it x=44
Step-by-step explanation:
I just divided 176 by 4 because it said the value of y varies directly with x. So just used the rule they used i guess.
Harry put blue and green marbles in a bag. Exactly 3/4 of the marbles in the bag are blue. Which of the following could be the total number of marbles in the bag.
A. 3
B. 6
C. 7
D. 8
Answer:
D
Step-by-step explanation:
Because when u multiply 3/4 times A,B,C it gives you a decimal, when u multiply 3/4 by 8 you get 6 a whole number.
The total number of marbles in the bag could be (d) 8
How to determine the possible total?We have:
Blue proportion = 3/4
This means that the green proportion is
Green proportion = 1 - 3/4
Evaluate
Green proportion = 1/4
Express as ratio
Blue: Green = 3/4 : 1/4
Simplify
Blue: Green = 3 : 1
Add the ratios
Total = 3 + 1
Total = 4
The above means that the total number of marbles in the bag is a multiple of 4
i.e. 4, 8, 12, 16, 20......
Hence, the total number of marbles in the bag could be (d) 8

4. Which of the following could be the areas of the three squares shown?
Answer:
Option (A)
Step-by-step explanation:
Three squares shown in the figure are formed on the sides of the given right triangle.
By Pythagoras theorem,
(Hypotenuse)² = (Leg 1)² + (Leg 2)²
Area of the square on the hypotenuse = Area of the square on the leg 1 + Area of the square on leg 2
Option (A).
95 = 40 + 55
True.
Option (B).
45 ≠ 35 + 25
False.
Option (C).
100 ≠ 10 + 10
False.
Option (D).
1200 ≠ 40 + 30
False
Therefore, Option (A) shows the areas of three squares.

Calculate the mean of Bryanna's test scores if she has scored 75, 97, and 92 so far this
semester
A 284
o
B
88
c. 75
D
Work Shown:
Add up the values
75+97+92 = 264
Then divide by 3 since there are 3 scores
264/3 = 88
You can write this all as one step
(75+97+92)/3 = 88
So in short, you add the scores and then divide by the number of scores.

A transversal crosses a pair of parallel lines to create a pair of same-side interior angles with the measurements of x° and (x−52)°. What is the value of x?
Answer:
x=116°
Step-by-step explanation:
If a transversal crosses a pair of parallel lines to create a pair of same-side interior angles with the measurements of x° and (x−52)°, then the sum of those angles is equal to 180°.
ATQ,
x°+(x-52)°=180°
2x=180°+52
⇒2x=232
⇒x=116°
So, the value of x is 116°
Audrey has already scored 53 points,and scored 22 more points with every coin she collects.How many coins does Audrey have to collect to score a total of 97 points
Answer:
Audrey needs to collect 3 more coins.
Step-by-step explanation:
Since she already scored 53 points, we have to find out how many more points she needs to score 97.
So, 97-53=45 points.
The problem says that each coin Audrey collects is worth 22 points. Therefore, 45 divided by 22= 2 remainder 1. However, if she only collects two more coins, Audrey will only have 96 points in total, not 97.
So, add another coin to make 3.

1. A hexagon is inscribed in a circle. If the difference between the area of the circle and the area
of the hexagon is 24 m”, use the formula for the area of a sector to approximate the radius
of the circle. Give an exact answer( doesn't have to be rationalized) and round to 2 decimals.
Answer:
The radius, r ≈ 6.55 m
Step-by-step explanation:
The given parameters are;
An inscribed hexagon in a circle
The area of the hexagon = Area of the circle - 24 m²
The formula for the area of the circle = π·r² = π × r²
The area of each of the six equilateral triangle in the hexagon = √3/4 × r²
Where;
r = The radius of the circle
The area of a sector of a circle in which the equilateral triangle is inscribed = 60/360×π·r² = 1/6×π·r² = 1/6 × Area of the circle
Given that the sector of the circle in which one of the six equilateral triangles of the hexagon is inscribed is 1/6 the area of the circle, the difference in area between the equilateral triangle and the sector = 24/6 = 4
Therefore, the difference in the area between the sector of the circle and the area of the equilateral triangle = 4 m²
We then write; 1/6×π·r²- √3/4 × r² = 4
r²·(1/6×π- √3/4) = 4
r² = 4/(1/6 ×π - √3/4) = 48/(2·π -3·√3)
r = √(48/(2·π -3·√3) = 6.55 m to 2 decimal places
The radius, r ≈ 6.55 m.
