Answer:
x = 15, y = 5
Step-by-step explanation:
total score of A = 6x
total score of B = 25*8 = 200
total score of C = 20y
(6x+200)/(x+25)=7.25
6x+200 = 7.25x+181.25
18.75 = 1.25x
x = 15
and
(6x+200+20y)/(x+25+20) = (6x+200+20y)/(x+45) = 6.5
plug in x
(290+20y)/60 = 6.5
290 + 20y = 390
20y = 100
y = 5

you really want to think of a function as a vending machine. if you selected B12 on a vending machine and got chips, the only thing that you should be getting is chips. B12 represents x, the input value, and the chips represent y, the output value. one input value can only have one output value. in this scenario, we can say that (5,2) is a function because we don’t have another 5 as an input value.
(0,2) is not an example of an input output value because we already have 0 as an input which would make it have two output values which is not possible. if you pressed B12 and got a drink even though you just got chips from it, that would not be a function.

Answer:
3.5 fluid ounces
Step-by-step explanation:
In this question, we are asked to calculate the capacity in fluid ounce of a cone-shaped cup.
To solve this, we need to calculate the volume of the cup.
Mathematically, the volume of a cone =
1/3 * π * r^2 * h
Where r = d/2 = 2.7/2 = 1.35 inches
h = 3.3 inches
By substituting this, we have
V = 1/3 * 3.14 * 1.35^2 * 3.3 = 6.3 cubic inch
Now we proceed to calculate the capacity
From the question, we are told that ;
1 fluid ounce = 1.8 cubic inch
This means
x fluid ounce = 6.3 cubic inch
x = 6.3/1.8
x = 3.5 fluid ounces

The area of the quadrilateral is equal to 15 square units.
What is an area?The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the quadrilateral in a two-dimensional plane is called the area of the quadrilateral. A quadrilateral is a four-sided polygon with four edges and four corners in geometry.
Given that the quadrilateral has a height of 3 units, the base is 3 units and the upper sides are 7 units.
The area of the quadrilateral is calculated by the formula,
Area = (1/2) x h x (a + b)
Substitute the values in the formula and calculate the area,
Area = (1/2) x 3 x (7 + 3)
Area = (10 / 2) x 3
Area = 5 x 3
Area = 15 square units

If w = 7 feet, x = 6 feet, y = 13 feet, and z = 8 feet, what is the area of the object?
Answers
Answer:
The Area is: 84ft
Step-by-step explanation:
multiply "Y" and "X" and you get 78ft.
"W" + "?"= "Y" If "W"=7, what is 13 ("Y") - 7? 13 -7=6. so "?"=6.
"Z"-"X"="?" "Z"=8 and "X"=6. so 8-6=2
2x6=12 *but remember that to find the area of a triangle it is half of a square of rectangle so you have to divide it in half. 12/2=6.
78+6=84.

Answers
First order the numbers
106,127,129,132,135,138,140,158
Now find the median (find the middle number)
It’s 132 and 135 so just add them together and divide by 2 so 133.5
Now to find Q1 you take the left overs from the first part of the medium and find the middle number
106,127,129,
⬇️
It’s 127 that’s the Q1
Now to find the Q3 you do the same thing but the upper half of the left overs
138,140,158
⬇️
Q3 is 140
Now that we know our Q1 is 127 and our Q3 is 140 we use the equation Q3-Q1
So
140-127=13

A custodian can clean 2 classrooms in 15 minutes. At this rate, how many classrooms can a custodian clean in 76 minutes?
Answers
Answer:
10 Classroom
Step-by-step explanation:
Since,
Custodian clean 2 classrooms in 15 minutes
Then ,
Let's see how many minutes does it takes for a custodian to clean for 1 classroom
To Find that we have to divide the given minutes by the given classroom.
15/2 = 7.5
Hence, in 7.5 minutes a custodian clean 1 classroom
Therefore:
Classroom to minutes:
1 = 7.5
2 = 15
3 = 22.5
4 = 30
5 = 37.5
6 = 45
7 = 52.5
8 = 60
9 = 67.5
10 = 75
11 = 82.5
Hence, we round to the nearest number:
which is 10 classroom in 75 minutes.
For this reason, the answer is about 10 classroom

These three theorems, known as Angle - Angle (AA), Side - Angle - Side (SAS), and Side - Side - Side (SSS), are methods for determining similarity in triangles.
As A has angles 90,25 and 65 and B has angles 90,45 and 45, there are no two pairs of angles that are similar. Also as the angles are not equal the sides can't also be equal. So none of the above three methods are applicable here.
