13 students are wearing purple uniform in a class of 21 students. Write the ratio of students wearing purple uniform to student NOT wearing purple uniform in the class.
Answer:
There are 16 students total.
1/4 (4 students)--> Yellow Costumes
6 students--> Purple Costumes
(?) students--> Orange Costumes.
We know that one fourth of the students is 4 students by doing simple division.
6 students are wearing purple costumes.
Add these together.
4+6 = 10
The remaining students are wearing orange costumes.
There are 6 students remaining.
Therefore, 6 students are wearing orange costumes.

Just need to know the perimeter and the area
Answer:
Perimeter = 68 m
Area = 273 m^2
Step-by-step explanation:
Perimeter = s + s + s + s
= 13 + 13 + 16 + 26
= 68 m
To find perimeter add all sides of the shape.
Area = 1/2 × ( 16 + 26 ) × 13
= 0.5 × 42 × 13
=273 m^2

Suppose you have 28 coins that are all dimes and quarters. The total value of the coins is $5.35. Write a system of equations that models this situation and solve the system to find the number of quarters and dimes.
Answer:
1) The system of equations that models this situation is given as follows
0.1·x + 0.25·y = 5.35...(1)
x + y = 28...(2)
2) The number of dimes = 11 dimes
The number of quarters = 17 quarters
Step-by-step explanation:
1) The given parameters are;
The numbers of quarters and dimes = 28
The total value of the coins = $5.25
Let x represent the number of dimes and y represent the number of quarters, and given that a dime = $0.1 and a quarter = $0.25, we have;
The system of equations that models this situation is given as follows
$0.1·x + $0.25·y = $5.35...(1)
x + y = 28...(2)
2) Making y the subject of both equations gives;
From equation (1), we have;
0.1·x + 0.25·y = 5.35
0.25·y = 5.35 - 0.1·x
y = 5.35/0.25 - 0.1/0.25·x = 21.4 - 0.4·x
y = 21.4 - 0.4·x
From equation (2), we have;
x + y = 28
y = 28 - x
Equating both equations to find the common solution, gives;
21.4 - 0.4·x = 28 - x
x - 0.4·x = 28 - 21.4
0.6·x = 6.6
x = 6.6/0.6 = 11
x = 11
The number of dimes = x = 11
y = 28 - x = 28 - 11 = 17
y = 17
The number of quarters = y = 17.

If Sarah fills up her gas tank with 20 gallons of gasoline and pays $46 for the gasoline, how much did she pay per gallon?
9514 1404 393
Answer:
$2.30 per gallon
Step-by-step explanation:
Price per gallon is found by dividing the cost by the number of gallons:
$46/(20 gal) = $2.30/gal
Sarah paid $2.30 per gallon.
Answer:
$2.30 per gallon
Step-by-step explanation:
We have to divided the price Sarah payed by the amount of gallons she bought.
46 ÷ 20 = 2.30
The answer is 2.30 per gallon.
The supermarket has 48 aisles. 12 of the aisles are empty. What percentage of the aisles are empty
Answer:
25% of the isles are empty
Step-by-step explanation:
48/12 is 25%
Answer:
25%
Step-by-step explanation:
12 + 12 + 12 + 12= 48

the population of a colony grows from 250 in the year 2000 to 400 in the year 2004. what is the average rate of change of population.
Given:
Population of a colony in 2000 = 250
Population of a colony in 2004 = 400
To find:
The average rate of change.
Solution:
Let y be the population of the colony at x year.
The population of a colony grows from 250 in the year 2000 to 400 in the year 2004. So, the two points are (2000,250) and (2004,400).
Formula for slope or average rate of change is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{400-250}{2004-2000}[/tex]
[tex]m=\dfrac{150}{4}[/tex]
[tex]m=37.5[/tex]
Therefore, the average rate of change of population is 37.5.

What is coordinate plane?A coordinate plane is a two-dimensional surface formed by two number lines. It is formed when a horizontal line (the X-axis) and a vertical line (the Y-axis) intersect at a point called the origin. The numbers on a coordinate grid are used to locate points.
Given that, use the coordinate plane to locate the quadrants.
In IV quadrant, the x-axis has positive numbers and the y-axis has negative numbers.
Here, the coordinates (1,-6), (5,-2) are located in IV quadrant.
