40% of the students in a class like apples for breakfast. If 20 students like apples, how many students are in the class.
Answer:
there are 50 people in the class
Step-by-step explanation:
20=%40
10=%20
5=%10
%10x10=%100
replace 10 percent with its equal, which is 5
5x10=50
The solution is 50 students
The total number of students in the class is 50 students
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the total number of students in the class be A
Now , the value of A is
The number of students in the class who likes apples = 20 students
The percentage of students who likes apples = 40 %
So , the equation will be
percentage of students who likes apples x total number of students in the class = number of students in the class who likes apples
Substituting the values in the equation , we get
( 40 / 100 ) A = 20
On simplifying the equation , we get
Multiply by 100 on both sides of the equation , we get
40A = 2000
Divide by 40 on both sides of the equation , we get
A = 2000 / 40
A = 50 students
Therefore , the value of A is 50 students
Hence , the total number of students is 50 students

Step-by-step explanation:
What are the x- and y-intercepts of the line? 2x – 3y = –12
Show work
Answer:
You can use the intercepts to graph the line. The graph of 2x + 3y = 12 crosses the x-axis at (6, 0), so its x-intercept is 6. The graph of 2x + 3y = 12 crosses the y-axis at (0, 4), so its y-intercept is 4.
Step-by-step explanation:
Answer:
x = -6 y = 4
(-6,0) (0,4)
Step-by-step explanation:
2x - 3y = -12
cancel out the y
2x - 3(0) = -12
2x = -12
divide both sides by 2
x = -6
2x - 3y = -12
cancel out the x
2(0) - 3y = -12
-3y = -12
divide both sides by -3
y = 4

The number of people living on a remote island decreases by 9% every 10 years. In 1950 there were 18000 living on the island. Calculate how many less people will be living on the island in 2020.
Answer: 9,301 people
Step-by-step explanation:
First find the number of years that have passed:
= 2020 - 1950
= 70 years
Population decreases every 10 years so in 7 years it would have increased:
= 70/10
= 7 times
In 2020 therefore:
= 18,000 * (1 - 9%)⁷
= 9,301 people

What is equation of a line?The equation of a line is a form of representing the set of points, which form a line in a coordinate system.
The general equation of a straight line is given as:
y = mx + c,
where m = slope of the line and c = y-intercept.
We have,
A line on a graph.
Three points are given on the graph:
(2, -8), (0, 2), and (7, 2)
We can select any two points and find the slope of the line.
The slope of a line is given as:
Slope = (d - b) / (c - a)
Where (a, b) and (c, d) are the two points.
(a, b) = (2, -8) and (c, d) = (0, 2)
Slope = (2 - (-8)) / (0 - 2)
Slope = (2 + 8) / -2
Slope = 10 / -2
Slope = -5
Thus,
The slope of the given line is -5.

An aquarium is leaking water at the rate of three quarts in 4 days.How many quarts are leaked in 1 week?How many days does it take for 9 quarts to leak out of the aquarium?
Answer:
[tex]\frac{21}{4}[/tex] quarts
12 days
Step-by-step explanation:
Given that:
Amount of water leaked in 4 days = 3 quarts
To find:
Number of quarts leaked in 1 week?
Number of days taken for the leakage of 9 quarts of water?
Solution:
We can simply use unitary method or the ratio to find the answers of the questions asked in the statement.
As per question statement:
Amount of water leaked in 4 days = 3 quarts
Dividing by 4 on both sides:
Amount of water leaked in 1 day = [tex]\frac{3}{4}[/tex] quarts
Multiplying by 7 on both sides:
Amount of water leaked in 7 days = [tex]\frac{3}{4}\times 7 = \frac{21}{4}[/tex] quarts
Number of days taken for the leakage of 3 quarts = 4 days
Multiplying by 3 on both sides:
Number of days taken for the leakage of 3 [tex]\times[/tex] 3 = 9 quarts = 4 [tex]\times[/tex] 3 = 12 days
Find the value of x in the figure.
(4x-5)
177
(4x-3)
(3x-3)
118
(3x+6)
Answer:
x = 35
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 6, then
sum = 180° × 4 = 720°
sum the given angles and equate to 720
4x - 5 + 117 + 3x - 3 + 3x + 6 + 118 + 4x - 3 = 720, that is
14x + 230 = 720 ( subtract 230 from both sides )
14x = 490 ( divide both sides by 14 )
x = 35
