To frame two problems of linear equation in one variable of your choice and solve such that the result of the first problem should be 79 and the next problem is 25.
Answers
Answer:
[tex]x + y = 79[/tex] and
[tex]x - y = 25[/tex]
[tex](x,y) = (52,27)[/tex]
Step-by-step explanation:
Let the variables be: x and y
The equations can be modelled as:
[tex]x + y = 79[/tex] and
[tex]x - y = 25[/tex]
To solve for x and y, we have:
Make x the subject in [tex]x - y = 25[/tex]
[tex]x = 25 + y[/tex]
Substitute [tex]x = 25 + y[/tex] in [tex]x + y = 79[/tex]
[tex]25 + y + y = 79[/tex]
[tex]25 + 2y = 79[/tex]
Collect like terms
[tex]2y = 79 - 25[/tex]
[tex]2y = 54[/tex]
Divide both sides by 2
[tex]y = 27[/tex]
Substitute [tex]y = 27[/tex] in [tex]x = 25 + y[/tex]
[tex]x = 25 + 27[/tex]
[tex]x = 52[/tex]
So, we have:
[tex](x,y) = (52,27)[/tex]

All you need to do to find angle x is to subtract 48 from 90 :)
So, 90 - 48 = 42
Angle x = 42 degrees
Hope this helps!
Answer:
anglePQR+anglePQS=90
or,48 degree+x=90
or,x=90-48
or,x=42
therefore the value of x is 42 degree

Volume=125 cu ft
Length=5 ft
Width=?___
Height=5 ft
Answers
Answer:
5 ft.
Step-by-step explanation:
First, start with a formula. To find the volume, you have to multiply the length, width, and height.
V = lwh
Plug in the variables that you already know.
125 = 5 ⋅ w ⋅ 5
Simplify.
125 = 25w
Divide both sides by 25 to isolate w.
5 = w

You observe the heights of two plants for an experiment. Plant A has a height of 8 centimeters and grows 1 centimeter each week. Plant B has
a height of 4 centimeters and grows 2 centimeters each week. Let x represent the number of weeks and let y represent the height of the
plant
a. Write a system of linear equations that represents this situation
System of equations:
b. Will the plants ever have the same height?
Answers
Using linear functions, it is found that:
a)
[tex]y_A(x) = 8 + x[/tex]
[tex]y_B(x) = 4 + 2x[/tex]
b) They will have the same height after 4 weeks.
A linear function has the following format:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change.b is the y-intercept, which is the value of y when x = 0.Item a:
Plant A has a height of 8 centimeters and grows 1 centimeter each week, hence:
[tex]y_A(x) = 8 + x[/tex]
Plant B has a height of 4 centimeters and grows 2 centimeters each week, hence:
[tex]y_B(x) = 4 + 2x[/tex]
The system is:
[tex]y_A(x) = 8 + x[/tex]
[tex]y_B(x) = 4 + 2x[/tex]
Item b:
Equaling the equations:
[tex]y_A(x) = y_B(x)[/tex]
[tex]8 + x = 4 + 2x[/tex]
[tex]x = 4[/tex]
They will have the same height after 4 weeks.

Animal shelters in a county need at least 15% of their animals to be adopted weekly to have room for the new animals that are brought into the various shelters. The county manager takes a random sample of shelters each week to estimate the overall proportion of animals that are adopted. If he concludes that the proportion has dropped below 15%, he will not accept any new animals into the shelters that week. He tests the hypotheses: H0: The adoption rate is 15%, and Ha: The adoption rate is less than 15%. What is a Type II error, and what is its consequence in this context
Answers
Answer:
By accepting a false null hypothesis he committed a type II error.
Step-by-step explanation:
Type II error is to accept H0 when H0 is false.
If there's a type II error then the null hypothesis is false ie the adoption rate is less than 15 %, when the true adoption rate is not less than 15% . He has accepted the null hypothesis as true and taken the wrong decision of not accepting any new animals into the shelters that week.
Answer:
A
The manager believes the adoption rate is still 15%, when it actually has dropped below 15%. The manager will accept more animals into the shelters and will run out of room.

Ziyad’s family owns a rectangular piece of land. If the length of the land is represented by 2x - 6 and the width is represented by 3x - 5, what polynomial represents the total area of this piece of land?
Answers
Answer:
Area of rectangular land = 6x² - 28x + 30
Step-by-step explanation:
Given:
Length of rectangular land = 2x - 6
Width of rectangular land = 3x - 5
Find:
Area of rectangular land
Computation:
Area of rectangle = Length × Width
Area of rectangular land = [Length of rectangular land][Width of rectangular land]
Area of rectangular land = [2x - 6][3x - 5]
Area of rectangular land = (2x)(3x) - (2x)(5) - (6)(3x) + (6)(5)
Area of rectangular land = 6x² - 10x - 18x + 30
Area of rectangular land = 6x² - 28x + 30
