The area of a triangle is 106 square feet. The base is twice the height. Find the height.
Answer:
The height is [tex]\sqrt{106}[/tex] feet
Step-by-step explanation:
First, lets assign and categorize the information given to us:
Area = 106 [tex]ft^{2}[/tex]
b = 2h (Base is twice the height)
Next, lets look at the formula for the area of a triangle:
Area = [tex]\frac{1}{2} bh[/tex]
Then, lets substitute the given information and solve:
106 = [tex]\frac{1}{2}[/tex] * 2h * h
106 = [tex]h^{2}[/tex]
[tex]\sqrt{106}[/tex] feet = h
LCD of (2/x^2) - (7/4x^2+12x)?
Answer:
4x³ + 12x²
Step-by-step explanation:
I assume the denominators are x² and 4x although that is not what you wrote.
x² = x² (already factored)
4x² + 12x = 4x(x + 3)
LCD = 4 × x² × (x + 3)
LCD = 4x³ + 12x²

Answer:
For no values of x.
Step-by-step explanation:
A function is increasing when its graph is sloping upwards.
Conversely, a function is decreasing when its graph is sloping downwards.
From the given graph, we can see that it is sloping downwards at all x values. In other words, it is always decreasing and never increases.
Therefore, for no values of x is the graph increasing.

A) 22cm
( divide the length value by 100)
22/100 which gives you:
=0.22m
B) 180km
( multiply the length value by 1000)
180×+100 which gives you:
=180000m
C) 300mm
( divide the length value by 1000)
300/1000 which gives you:
=0.3m

Finding m∠R

∠C = 360° - 100° - 40° / 2∠C = 220°/2 = 110°∠C + ∠D = 180°110° + ∠D = 180°∠D = 70°Opposite angles of an inscribed quadrilateral is supplementary

m<D=180-110=70°Tank A fills at a rate of 6 gallons per hour and discharges water at a rate of 69 gallons per day. If the tank starts out empty, how much water would be in the tank after 24 hours
The tank fills up at a daily rate of
(6 gal/hr) (24 hr/day) = 144 gal/day
so the net rate is
144 gal/day - 69 gal/day = 75 gal/day
and after 24 hours, the tank would contain 75 gal of water.
75 gallons of water would be in the tank after 24 hours.
How to elaborate the problem ?
Tank A fills at a rate of 6 gallons/hr
We know that, 1 day = 24 hours
So, Tank A fills in a day = (6 × 24) gallons
Given that, The tank discharge water at a rate 69 gallons per day.
How much water would left after 24 hours ?Total water in the tank A in 24 hours = 144 gallons
Tank A discharge water in 24 hours = 69 gallons
∴ Water left in the tank A after 24 hours = (144-69) gallons
= 75 gallons

A rectangle has sides measuring (2x + 7) units and (5x + 9) units.
Part A: What is the expression that represents the area of the rectangle? Show your work. (4 points)
Part B: What are the degree and classification of the expression obtained in Part A? (3 points)
Part C: How does Part A demonstrate the closure property for polynomials? (3 points)
Answer:
A: 10x^2 +53x +63 B: degree 2; quadratic trinomial C: the result of the multiplication of polynomials is a polynomial
Step-by-step explanation:
Part A:
The area is the product of length and width. The distributive property is useful for simplifying the expression.
A = LW
A = (2x +7)(5x +9) = 2x(5x +9) +7(5x +9)
A = (10x^2 +18x) +(35x +63)
A = 10x^2 +53x +63 . . . . area expression
Part B:
The highest power of x is 2. There are 3 terms. A degree-2 polynomial is called a "quadratic." A 3-term polynomial is called a "trinomial."
degree 2
quadratic trinomial
Part C:
In part A we multiplied two polynomials and came up with a result that is a polynomial. This suggests polynomials are closed with respect to multiplication.

7x – y = 7
7x2 – y = 7
(0, 7) and (0, –7)
(1, 0) and (0, –7)
(3, 14) and (0, –7)
(4, 14) and (–1, 10)
Answer:
2nd option
Step-by-step explanation:
7x - y = 7 ( multiply through by - 1 )
- 7x + y =- 7 ( add 7x to both sides )
y = 7x - 7 → (1)
7x² - y = 7 → (2)
substitute y = 7x - 7 into (2)
7x² - (7x - 7) = 7 ← distribute parenthesis on left side
7x² - 7x + 7 = 7 ( subtract 7 from both sides )
7x² - 7x = 0 ← in standard form
7x(x - 1) = 0 ← in factored form
equate each factor to zero and solve for x
7x = 0 ⇒ x = 0
x - 1 = 0 ⇒ x = 1
substitute these values into (1) for corresponding values of y
x = 0 : y = 7(0) - 7 = 0 - 7 = - 7 ⇒ (0, - 7 )
x = 1 : y = 7(1) - 7 = 7 - 7 = 0 ⇒ (1, 0 )

Nicole is on her way home in her car. She has driven 10 miles so far, which is one-half of the way home. What is the total length of her drive?
Answer:
20 miles
Step-by-step explanation:
10 x 2 = 20
10 miles is half the drive so you'd just multiply it by 2 and that would be the full amount of miles home.
Answer:
The total length of Nicol’s drive would be 20 miles.
If The first half of her trip takes 10 miles then the second half would have an equal number of miles. 10x2=20
You would use 10 two times because 1/2+1/2=1.
Therefore the total amount of miles Nicole will travel will be 20.

The chart below shows the results of survey taken by a movie theater. The theater asked what genre the mover goers preferred to see. If the theater owner asked 100 people, how many people would prefer Drama? Round to the nearest whole number
Answer: Hence the cost of operating theater if there are 100 people at a show is 20,000Rs.
Step-by-step explanation:
Theater is a place where the movies are shown in big screens and Speakers are used for the clear audio of the movie.
In a theater there will be 3 to 4 shows for a movie or different movie.
Theater can consist of 250 - 300 seats and can cost up to 250rs for a seat.
Consider a ticket cost of 200rs. For 100 people in a show ,
Cost = 200 × 100
Cost = 20,000.
Hence the cost of operating theater if there are 100 people at a show is 20,000Rs.

solving,
x+2x+6x+18=180
or, 9x + 18 = 180
or, x + 18 = 180/9
or, x + 18 = 20
or, x = 20 - 18
or, x = 2
