if a rectangular plot of land is 30mt by 20mt . what is the ration of its area and perimeter
Answer:
Step-by-step explanation:
600mt^2 is the area. Area= length times width. 30 by 20. 30 times 20 is 600
100mt is the perimeter. 30 by 20. meaning that two sides are 30 and two sides are 20. 30 plus 30 plus 20 plus 20 is 100

the perimeter of a triangle is 41x. if the length of two sides are 18x and 7x, find the length of the third side in terms of x.
Answer: 16x
because the perimeter of a triangle is 41x
=> the length of the third side is 41x - 18x - 7x = 16x
Step-by-step explanation:
Answer:
➩ The third side is 16x units.
Step-by-step explanation:
Given that,
Perimeter of a ∆ is 41x It's two sides are : 18x and 7xWe need to find the third side in terms of x
We know that,
Perimeter of the ∆ = Sum of all sides
Therefore,
We can say that,
➡ 41x = 18x + 7x + third side
➡ 41x = 25x + third side
➡ 41x - 25x = third side
➡ 16x = third side
Hence,
The third side is 16x units.

9. Rich is a number of a gym. He pays a monthly fee plus a per-visit fee. The equation
below represents the monthly amount Rich pays for his membership to the gym per
month for x visits.
y = 3x + 10
What does the y-intercept of the graph of this equation represent?
Answer: it is the monthly fee
Step-by-step explanation: In y=3x+10 the y is the total amount he payed per month. The 3x is saying he payed $3 per visit (x) and slope, and the 10 is the monthly fee and y- int. He payed $10 at the start of each month.
The y-intercept of the graph is 10, which represents the monthly fee that Rich pays to the gym regardless of the number of visits.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
The given equation is, y = 3x + 10
This is in the form of a linear equation, where y represents the total cost per month and x represents the number of visits. The coefficient of x is 3, which represents the per-visit fee that Rich pays. The constant term is 10, which represents the monthly fee that Rich pays regardless of the number of visits.
The y-intercept of the graph of this equation is the value of y when x is equal to 0. Substituting x = 0 into the equation, we get,
y = 3(0) + 10
y = 10
Therefore, the y-intercept of the graph is 10, which represents the monthly fee that Rich pays to the gym regardless of the number of visits.

Darius buys a bottle of a chemical solution that contains 70, percent alcohol. The bottle contains 500 milliliters of solution. How many milliliters of alcohol are in the solution?
Answer: There are 350 milliliters of alcohol in the bottle
Step-by-step explanation:
Step 1
The amount of solution contained in the bottle = 500 millilitres
The percentage of alcohol contained in the bottle of 500 millilitres= 70%.
Therefore amount of alcohol in the solution is 70% of 500 millilitres
Step 2 --- Solving we have
70/100 × 500 = 0.70 x 500 = 350 ml
There are 350 millilitres of alcohol in the bottle.

What is a line plot ?A line plot is a graph that shows data as points or check marks above a number line, indicating the frequency of each value.
If we need to compare two different groups , a line chart does have one advantage for visualizing frequency distributions
It displays information as a series of data points called 'markers' connected by straight line segments
Given data ,
Let the point on the line be n
Now , the value of n = -2
And , the opposite value of n is given by the number multiplied by -1
So , the opposite value of n = ( -2 ) x -1
The value of D = 2
So , the point on the line is D = 2
Hence , the opposite number is D = 2

Answer:
Nope, not function
Step-by-step explanation:
If you draw a line down from any point on the line the is graphed (not x and y line), you can see there is two points that intercepts the original line. A function is where when you draw a line through the original line, there will be only one intercepting point. A non-function is when you draw a line down the original line, there will be TWO intercepting line.

What angles must be congruent to QPS?
Answer:
QTS & TQS
Step-by-step explanation:
so as PQ=QT is given & QS is an common side, you can take the triangle PQS & TQS as isosceles triangles.
so then the angles PSQ=QST becoz the angles opposite to equal sides of an isosceles triangle are also equal in measures.
PQ=QT (given)
QS = common side
PSQ=QST (the angles opposite to equal sides of an isosceles triangle are also equal in measures.)
Therefore PQS is congruent to QTS (S.S.A)

A lot is 25 m wide and 120 m long. How
many metres must be added to both the
length and the width to increase the area
by 750 square metres?
Answer:
5 meters must be added to both the length and the width
Step-by-step explanation:
Area of a Rectangle
A rectangle of width W and length L has an area calculated as:
A = W*L
Initially, the lot has a width of W1=25 m and a length of L1 = 120 m, thus its area is:
[tex]A_1 = 25 * 120 = 3,000~m^2[/tex]
When adding x meters to the width and the length, the new area is:
[tex]A_2=(25+x)(120+x)[/tex]
Operating:
[tex]A_2=x^2+145x+3,000[/tex]
We now calculate the increased area by subtracting A2-A1:
[tex]A=x^2+145x+3,000-3,000[/tex]
[tex]A=x^2+145x[/tex]
We are given this area is 750 square meters, thus:
[tex]x^2+145x=750[/tex]
Rearranging:
[tex]x^2+145x-750=0[/tex]
Factoring:
[tex](x-5)(x+150)=0[/tex]
Solving:
x=5, x=-150
Taking the positive solution x=5:
5 meters must be added to both the length and the width
