Christina is packing different books into boxes. The paperback books weigh 0.8 pounds each. The hardcover books weigh 1.3 pounds each. Christina needs to pack the boxes so that there are at least 20 books in each box, but the boxes cannot weigh more than 30 pounds.

Identify Christina’s set of constraints.

Answers

Answer 1

Answer:

P + H ≥ 20

P*0.8 lb + H*1.3 lb ≤ 30lb

Step-by-step explanation:

Let's define H as the number of hardcover books.

Let's define P as the number of paperback books.

Now we have the restrictions:

"... so that there are at least 20 books in each box..."

Then:

P + H ≥ 20   (the total number of books per box is 20 or larger)

"...but the boxes cannot weigh more than 30 pounds."

P*0.8 lb + H*1.3 lb ≤ 30lb (the maximum weight that we can have in the box is 30 pounds)

Then the set of constraints is:

P + H ≥ 20

P*0.8 lb + H*1.3 lb ≤ 30lb

Notice that this system has a lot of possible solutions.

P = 20 and H = 0 is  a solution

P = 21 and H = 0 is a solution.

P = 19 and H = 1 is a solution.

What is the standard form polynomial representing the volume of this shipping container?
6x + 15
4x² + 3x
x² – 8

Answers

Answer:

Step-by-step explanation:

Volume of the shipping container = Lengt * Breadth * Height

Given

Length = 4x² + 3x

Breadth = x² – 8

Height = 6x +15

Volume of the container = ( 4x² + 3x)( x² - 8)(6x+15)

( 4x² + 3x)( x² - 8)  = 4x⁴-32x²+3x³-24x

( 4x² + 3x)( x² - 8) = 4x⁴+3x³-32x²-24x

(4x⁴+3x³-32x²-24x)(6x+15) = 24x⁵+60x⁴+18x⁴+45x³-192x³-480x²-144x²-360x

Collect like terms

( 4x² + 3x)( x² - 8)(6x+15) = 24x⁵+78x⁴-147x³-624x²-360x

Hence the standard form polynomial representing the volume of this shipping container is expressed as V = 24x⁵+78x⁴-147x³-624x²-360x

Answer:

V = 24x^5+78x^4-147x^3-624x^2-360x

77 is written as the product of two prime numbers 7 × 11. Can 702 be written as the product of two prime numbers? If not, why? What about 703?​

Answers

Answer:

702 can't be written as the product of 2 prime numbers because if you divide 702 by 2 then you get 351 and that is not a prime number. Therefore, 702 is a prime number.

The prime factorization of 703 is 19 × 37. Since it has a total of 2 prime factors, 703 is a composite number.

Lionel computed the average rate of change in the depth of a pool over a two-week interval to be zero. Which statement must be true? The pool must have been empty for the entire interval. The pool must have been the same depth at the start of the interval as it was at the end of the interval. The pool must have been deeper at the end of the interval than it was at the start of the interval. The pool must have been more shallow at the end of the interval than it was at the start of the interv

Answers

Answer:The pool must have been the same depth at the start of the interval as it was at the end of the interval.

Step-by-step explanation:

The average rate of change is calculated as:

[final value - initial value] / time interval.

Then, the average rate of change does not take into account intermediates values, and you cannot draw any conclusion about such intermediate values.

In the given case you have:

average rate of change in depth = [final depth - initial depth] / 2 weeks.

0 = [final depth - initial depth] / 2 weeks.

⇒ 0 = final depth - initial depth

⇒ final depth = initial depth.

That is why the conclusion is the second statement of the answer choices: the pool must have been the same depth at the start of the interval as it was at the end of the interval.

In between the pool might have been deeper, more shallow, empty or change in any form, since the average rate of change does not tell the full history but only the net change.

Answer:

The pool must have been the same depth at the start of the interval as it was at the end of the interval.

Use the associative property to create equivalent expressions to a + b + (c + d). Which statements are true? Check all that apply. The associative property allows us to change the grouping of terms that are added together. When changing the grouping, the order of the terms stays the same; only the parentheses change position. The expression a + (b + c) + d is an equivalent expression. The expression ab(cd) is an equivalent expression. The expression (a+ b) + c + d is an equivalent expression. The expression a + b(c + d) is an equivalent expression.

Answer: I HOPE IT HELPS OR WATCH  VIDOES  ABOUT IT

Step-by-step explanation:

Two unique points define a line.  Other geometric figures also may pass through those two points (you will learn those later).

There are several forms of the equation of a line:

     Standard form                           Ax + By = C

     Slope-intercept form                  y = mx + b

     Point-slope form                        y – y1 = m(x – x1)

     Two-point form              y – y1 = [ (y2 – y1)/(x2 – x1) ](x – x1)

O.K., you picked the two-point form, right?    

               The points are  P1:  (5,5) and P2: (7,-4)

    y - 5 = [ ((-4) - 5)/(7 - 5) ] (x - 5)          (put in x and y values of points)

    y - 5 = [  -9 / 2 ](x - 5)                         (simplify)

    y - 5  =  -9/2x  + 45/2                           (distribute -9/2)

     y =  f(x) = -9/2x + 55/2                   (add 5 to both sided)

Check (very important):

  Is (5,5) on the line?      5 = (-9/2)(5) +  55/2  ?

                                         5 =  -45/2   +  55/2  ?

                                          5 =  10/2         yes.

  Is (7,-4) on the line?     -4 = (-9/2)(7) + 55/2       ?

                                          -4  =  -63/2   + 55/2   ?

                                          -4  =   -8/2   ?       yes.

Subtract 8x from both sides.

3x−2−8x=8x+8−8x
