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 solution of the given expression  (x − 2)(x 10) = 13 are x=3 or x=-11. So the option A is correct.

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

(x-2)(x+10) = 13

Subtract 13 from both sides

x²+8x-20-13=13-13

x²+8x-33=0

Factorized

(x-3)(x+11)=0

x-3=0 or x+11= 0

x=3 or x=-11

Thus, The answer is A

The regression solved shows that the predicted selling price for a home that is 12 years of age is $443747.

From the complete information, the regression equation is given as:

y = 108597.37 - 580.687 × age + 86.82 × living areas + 31261.9127 × bedroom

Therefore, the predicted selling price will be:

= 108597.37 - 580.687 × 12 + 86.82 × 2500 + 31261.9127 × 4

= $443747

In conclusion, the selling price is $443747.

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 )

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.

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.

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

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.

Step-by-step explanation:

Given equation is C = 2p + 35

and the C is $65

Putting the value of c in equation

=> 65 = 2p + 35

=> 65-35 = 2p

=> 30 = 2p

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

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.

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.
