The area of a square is given by the formula A=s, where s is the length of the side. What is the area of the square shown?
Answer:
a^4b^2
Step-by-step explanation:
s represents one side, or a^2b
so if s^2=A and s=a^2b then A=(a^2b)^2 or a^4b^2
The area of a rectangle is 35x4y10 square feet. If the length of the rectangle is 7x2y5 feet, which expression represents the width of the rectangle?
Answer: [tex]5x^2y^5[/tex]
Step-by-step explanation:
Given: Area of rectangle = [tex]35x^4y^{10}[/tex] square feet
Length of rectangle= [tex]7x^2y^5[/tex]
We know that,
Width of rectangle = [tex]\dfrac{\text{Area of rectangle}}{\text{Length}}[/tex]
Then,
Expression of width= [tex]\dfrac{35x^4y^{10}}{7x^2y^5}[/tex]
[tex]=\dfrac{5x^{4-2}y^{10-5}}{1}\ \ \ \ [\frac{x^m}{x^n}=x^{m=n}]\\\\=5x^2y^5[/tex]
Hence, the expression for width of the rectangle = [tex]5x^2y^5[/tex]

The sum of outer angles of a polygon is twice the sum of inner angles. How many sides does it have?
Answer:
3 sides
Step-by-step explanation:
sum of exterior angles for all polygons is 360°
sum of interior angles for a polygon can be found by using the formula:
(n - 2) · 180° where 'n' is the number of sides
'sum of outer angles' = 360
'twice the sum of inner angles' = 2n
360 = 2n
n = 180
a three-sided polygon (triangle) has 180 degrees

Find the value of x in the given
right triangle.
10
37°
x = [?]
Enter your answer as a decimal rounded to the
nearest tenth.
Enter
Answer:
x = 6.0
Step-by-step explanation:
As the given triangle is a right-angled triangle, we can use the trigonometric ratios to find the required length.
In the given triangle
Hypotenuse = 10
Perpendicular = x
Angle = 37°
As we know the value for perpendicular and hypotenuse, sine will be used.
[tex]sin\ 37 = \frac{Perpendicular}{Hypotenuse}\\sin\ 37 = \frac{x}{10}\\0.6018 = \frac{x}{10}\\x = 0.6018*10\\x = 6.018[/tex]
Rounding off to nearest tenth
x = 6.0
Hence,
x = 6.0

Bob walks up to a tank of water that can hold 75 gallons. When it is active, a drain empties water from the tank at a constant rate. When Bob first sees the tank, it contains 15 gallons of water. 4 minutes later, the tank contains 12 gallons of water.
A. At what rate is the amount of water in the tank changing? answers: 3/4, -3, -3/4, 3
B. How many more minutes will it take for the tank to drain completely?
C. How many minutes before Bob arrived was the tank completely full?
Answer:
A) -3/4
B) 15 more minutes
C) 80 minutes
Step-by-step explanation:
A. rate of change = -3/4
B. 16 minutes
C. 1 hour 20 minutes
What is slope?The slope is defined as the ratio of the vertical change between two points, the rise, to the horizontal change between the same two points, the run.
Given:
A) At first the tank contain 15 gallons of water.
After 4 minutes the tank contain 12 gallons of water.
So, rate of change
=12-15/4-0
=-3/4
=-3/4
B) now, Let x be the number of minutes will it take for the tank to drain completely.
So,
(3/4 gallons per minute) *x = 12 gallons
x = 12*4/3
x = 16 minutes
C) As, the tank has capacity of 75 gallons.
So, the tank of water is full when there is 10 gallons of water which is 60 gallons more.
Let 'y' be the number of minutes before Bob arrived when the water tank was completely full.
(3/4) (y) = 60
y = 60*4/3
y= 80 minutes
y= 1 hour 20 minutes

Angles in a triangle add up to 180
180 - (29+82) = 69
Angles on a straight line add up to 180
180 - 69 = 111
Answer:
111°
Step-by-step explanation:
the sum of the outer angles of a triangle is alway 180
so 180-82-29= 69°
180-69= 111°
Give an example of a real-world cost that depends on an unknown amount of something. Try to create an expression to represent the total cost.
Answer:
Ok, let's suppose that the unknown amount is the number of books you buy in a library. (let's represent this unknown quantity with the variable X)
We know that each book costs $9.75, and we know that in total cost for the X books is $68.25
Then, how many books do you get?
We know that if one book costs $9.75, then X books will cost X times $9.75
Then the total cost is:
C(X) = X* $9.75
And we know that the total cost was $68.25
Then to solve this, we need to solve the equation:
X* $9.75 = $68.25
X = $68.25/$9.75 = 7
The equation that can be used to represent the information is the cost of a book is $3, find the number of books when a customer pays $21.
To represent the scenario, the cost of a book is $3, find the number of books when a customer pays $21.
Therefore, the number of books will be:
3x = 21
x = 21/3
x = 7
In conclusion, the correct option is $7.

1. Write out the law of cosines and find the hypotenuse of triangle with 2 sides lengths equal to three and the included angle measuring 75 degrees.
2. What happens in law of cosines formula if the angle from the above question is changed to 90 degrees.
Answer:
1.) [tex]\sqrt{13.341}[/tex] ≈ 3.652
2.) I would say something about how the A in front of cos in the equation would change to 90, rather than stay 75 (in the equation for the step by step), but it would be easier to just use the Pythagorean theorem.
Step-by-step explanation:
I think we may have the same class so hopefully this helps:
1.) [tex]a^2 = b^2 + c^2 - 2bccosA[/tex] --> law of cosines formula.
[tex]a^2 = 3^2 + 3^2 - 2(3)(3)cos(75)[/tex] --> plugged in numbers; when you draw the triangle, the included angle would be A, and the opposite side would be a. B and b, and C and c are opposite each other. In this case, a is the hypotenuse.
[tex]a^2 = 18 - 18cos75[/tex] --> in between steps.
[tex]a^2 = 13.341[/tex] --> more simplifying.
[tex]a(hypotenuse) = \sqrt{13.341} or 3.652[/tex] --> answer
2.) This one is just an explanation: The 75 in the equation is the given angle, which is a. If this changes, it would just change in the equation too. And obviously, if it's 90 degrees, you can just use Pythagorean theorem a^2+b^2=c^2.

An artist mixes 25 ounce of blue paint with 115 ounce of green paint. Using the same ratio, how many ounces of green paint should she mix with 3 ounces of blue paint?
Answer:
Ounces of green paint needed = 13.8
Step-by-step explanation:
Blue paint : green paint = 25 : 115
how many ounces of green paint should she mix with 3 ounces of blue paint?
Let
Ounces of green paint needed = x
Blue paint : green paint = 3 : x
Equate both ratios
25 : 115 = 3 : x
25/115 = 3/x
25 * x = 115 * 3
25x = 345
x = 345/25
x = 13.8 ounces
Ounces of green paint needed = 13.8
Cameron buys mobile games via an app store on his phone. the relationship between the number of games downloaded, x, and the total cost in dollars of the downloads, y, is represented by the graph below.
what point on the graph represents the unit rate?
Answer:
(1, 0.5)
Step-by-step explanation:
From the graph attached,
x-values are representing the number of games downloaded,
y - values are representing the total cost.
Unit rate means rate of 1 game downloaded.
If we represent this in terms of coordinates,
x- value (game downloaded) = 1
y - value (price of one game download) = $0.5
Therefore, point (1, 0.5) will represent the unit rate.
Option (2) on the top row will be the answer.

Answer:

Step-by-step explanation:
Using the sine and cosine ratios in the right triangle and exact values
sin60° = [tex]\frac{\sqrt{3} }{2}[/tex] , cos60° = [tex]\frac{1}{2}[/tex] , then
sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{4\sqrt{2} }[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )
2x = 4[tex]\sqrt{6}[/tex] ( divide both sides by 2 )
x = 2[tex]\sqrt{6}[/tex]
---------------------------------------------------------
cos60° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{y}{4\sqrt{2} }[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
2y = 4[tex]\sqrt{2}[/tex] ( divide both sides by 2 )
y = 2[tex]\sqrt{2}[/tex]
