The sides of a rectangular room are perpendicular to each other.
If these sides measure 10m and 12m respectively. Find the total
area of the carpet needed to cover the floor of the room?
Answer:
120 m^2
Step-by-step explanation:
Length of the room = 10 m
Breadth of the room = 12 m
We know that, Area = Length * Breadth
Hence,
Total Area of carpet needed to cover the floor of the room = 12 * 10 = 120 m^2

Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesAlgebra I
Solving systems of equations using substitution/eliminationSolving systems of equations using graphingStep-by-step explanation:
Step 1: Define systems
3x + y = 2
4x + 3y = 3
Step 2: Rewrite systems
y = 2 - 3x
4x + 3y = 3
Step 3: Solve for x
Substitute in y: 4x + 3(2 - 3x) = 3Distribute 3: 4x + 6 - 9x = 3Combine like terms: -5x + 6 = 3Isolate x term: -5x = -3Isolate x: x = 3/5Step 4: Solve for y
Define original equation: 3x + y = 2Substitute in x: 3(3/5) + y = 2Multiply: 9/5 + y = 2Isolate y: y = 1/5Step 5: Check
Graph the systems of equations.
Answer:
x = 3/5, y = 1/5
Step-by-step explanation:
Starting with:
3x + y = 2
4x + 3y = 3
Multiplying the first equation by -3:
-9x - 3y = -6
4x + 3y = 3
Adding the equations:
-5x = -3
Simplifying:
x = 3/5
Substituting x = 3/5 into the first equation:
9/5 + y = 2
Subtracting:
y = 1/5
A city park has a large circular garden with a path around it. The diameter of the garden is 60 feet. Jason works for the City Park Department. He needs to spread plant food all over the garden. What is the area of the park he will cover with plant food?
Answer:
He will cover 2,827.433 feet² area of the park with plant food.
Step-by-step explanation:
The diameter of the garden is 60 feet and the radius will be 60 feet/2 = 30 feet.
diameter= 60 feet
radius = diameter/ 2= 60/2= 30 feet
The area of the circle can be found by the formula πr²
Area= πr²=π(30)²
Area = 900π= 2,827.433 feet²
He will cover 2,827.433 feet² area of the park with plant food.

Answer:
There is 2145.52 cubic inches of air in the ball
Step-by-step explanation:
A round ball is an example is hollow sphere. In order to find how much air the ball holds, the volume of the sphere needs to be found.
Given
Radius = r = 8 in
The volume of sphere is given by:
[tex]V = \frac{4}{3} \pi r^3[/tex]
Putting the values we get
[tex]V = \frac{4}{3} * \frac{22}{7} * (8)^3\\V = \frac{4}{3} * \frac{22}{7} * 512\\V = \frac{45056}{21}\\V = 2145.52\ in^3[/tex]
Hence,
There is 2145.52 cubic inches of air in the ball

Which property should Remus use to solve the equation
below?
7q=49
Answer: It should be division property of equality.
Answer:
Division Property of Equality
Step-by-step explanation:
To solve this problem Remus needs to isolate the variable, which means to get rid of the 7. Since the 7 is being multiplied the opposite operation needs to be used; the opposite of multiplication is division. So each side needs to be divided by 7, the division property of equality tells us that an equation can be divided by anything as long as it is done on both sides. So to solve use the division property of equality to do 7q/7=49/7, which equals q=7 when simplified.

If group of boy scouts are hiking the Appalachian Trail. They determine that they are traveling at a rate of 5 miles every 2 hours. It took 4hrs them to travel 10 miles.
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Given,
A group of boy scouts are hiking the Appalachian Trail.
They are traveling at a rate of 5 miles every 2 hours
We need to find how long will it take for them to travel 10 miles at the same rate.
Let x be the required time
5/2=10/x
Apply cross multiplication
5x=20
Divide both sides by 5
x=4
Hence it took for them 4 hours to travel 10 miles of distance

Write the slope-intercept form of an equation for the line that passes through (2, 3) and is parallel to the graph of y = 2x -1
Answer:
ok
Step-by-step explanation:
Answer:
y = 2x -1
Step-by-step explanation:
when a two lines are parallel to each other that means they have the same slope.
you use point slope formula to find a line with the same slope and passes through (2,3)
y - y' = m(x - x') is the general form so you plug in (2,3) and the slope and you get
y - 3 = 2(x -2)
first your distribute the 2 into the parenthesis and you get
y-3 = 2x -4
now add 3 to both sides
y = 2x -1

John ate 40% of the candies in a bag. If John ate 20 candies , how many candies were total in the bag ?
Answer:
50
Step-by-step explanation:
There are 50 candies in the bag.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
John ate 40% of the candies in a bag.
If John ate 20 candies.
let the total number of Candies be x.
So, 40% of x = 20
40/ 100 x = 20
x = 2000/ 40
x= 50
Hence, there are total 50 Cadies.

Victor has a bag of dimes and quarters. He has a total of 36 coins worth $5.40.
Let x represent the number of dimes and y represent the number of quarters.
Which system of equations would be used to find out how many dimes and quarters Victor has?
{x+y= 5.4
0.1x +0.25y =36
{x=36−y
x+y=5.4
{y=x+36
x+y=5.4
{x+y=36
0.1x+0.25y=5.4
Answer:
{x+y=36
0.1x+0.25y=5.4
Step-by-step explanation:
just took the test sorry for being late
The system of equation that is used to find how many dimes and quarters Victor has is :
x + y = 36
0.1x + 0.25y = 5.40
x = number of dimes
y = number of quarters
Therefore,
Total number of coins will be
x + y = 361 dime = $0.1
1 quarters =$0.25
Therefore,
Total amount of dollars will be
0.1x + 0.25y = 5.40combine the equations:
x + y = 36
0.1x + 0.25y = 5.40
Therefore, the system of equation that is used to find how many dimes and quarters Victor has is as follows:
x + y = 36
0.1x + 0.25y = 5.40

How many 2 3 -quart portions are in 7 1 2 quarts of soup?
Answer:
[tex]Number = 11\frac{1}{4}[/tex]
Step-by-step explanation:
Given
[tex]Soup = 7\frac{1}{2}[/tex] quarts
[tex]Portion = \frac{2}{3}[/tex] quarts
Required
Determine the number of portions in the soup
The question illustrates division of fractions and to solve this question, we simply divide the size of the soup by the size of the given portion
[tex]Number = Soup/Portion[/tex]
Substitute values for Soup and Portion
[tex]Number = 7\frac{1}{2}\ quarts /\frac{2}{3} \ quarts[/tex]
[tex]Number = 7\frac{1}{2}/\frac{2}{3}[/tex]
Convert mixed fraction to improper fraction
[tex]Number = \frac{15}{2}/\frac{2}{3}[/tex]
[tex]Number = \frac{15}{2} * \frac{3}{2}[/tex]
[tex]Number = \frac{15*3}{2*2}[/tex]
[tex]Number = \frac{45}{4}[/tex]
[tex]Number = 11\frac{1}{4}[/tex]
Hence, there are [tex]11\frac{1}{4}[/tex] of [tex]\frac{2}{3}[/tex] quarts in [tex]7\frac{1}{2}[/tex] quarts of soup
