Answer:

[tex]\frac{1}{2}[/tex] hour later

Step-by-step explanation:

Since Mr.A has already traveled 25 miles there are 53 miles left to person B's house. In half an hour, Mr. A will have traveled 25 miles, while person b will have traveled 28. 25 + 28 = 53.

The volume V(x) in cubic inches of the open-top box is (15[tex]x^{2}[/tex] - 2[tex]x^{3}[/tex])

and side of length x in inches of the square cutouts is

V(1) = 15 - 2 = 13

x ∠ 7.5

The vertical sides were 15 inches before we cut out the corners.  

The horizontal sides were 15 inches before we cut out the corners.

So now, if you fold all of the "tabs" up, you get a box that has a height of "x".  

The sides are now each missing a length of "x" from each end.  

So the longer edges of the box are now (15 - 2x) long.  

The shorter edges of the box are now (15 - 2x)

The volume of a box is given by V = (length)(width)(height)

 length = 15 - 2x

width and height of the box are equal to x in so

Multiply these together and get:

V(x) = (15 - 2x)(x)(x)

V (x)  =  (15[tex]x^{2}[/tex] - 2[tex]x^{3}[/tex])

let x = 1

V (x) =  (15[tex]x^{2}[/tex] - 2[tex]x^{3}[/tex])

V(1) = 15 - 2 = 13

First x must be greater than 0,

then, we have 2x ∠ 15

                          x ∠ 7.5

therefore, The volume V(x) in cubic inches of the open-top box is (15[tex]x^{2}[/tex] - 2[tex]x^{3}[/tex])

side of length x in inches of the square cutouts is

V(1) = 15 - 2 = 13

x ∠ 7.5

This unit has two parts:

The surface area of a box, and its volume

The length of the diagonal of a box

Each student should bring an empty cereal box (or some other box) to work on. (The length, width, and height of the box should all be different.)

Formula for the area of the surface

(a) If l, w, and h are the length, width, and height of a box, its surface area is given by surface area = 2*(l*w + l*h + w*h). (Do you see it?)

(b) Measurements

Measurements are made in inches and sixteenths of an inch, but they are recorded as decimals.

1/8 inch = .125 inch, ¼ inch = .25 inch, 3/8 inch = .375 inch, ½ inch = .5 inch, and so on.

Example:

length l = 8.375 inches

width w = 6.125 inches

height = 2.25 inches

(c) How to enter these measurements into a TI-108 calculator to get the surface area:

8.375*6.125 M+       51.29…

8.375*2.25 M+         18.84…

6.125*2.25 M+         13.78…

MRC * 2 =                167.84… square inches

We round this to 168 square inches (more or less)

Part 1b. We can also find the volume of the box:

volume = l*w*h = 8.375*6.125*2.25 = 115.4… cubic inches

If this were a hands-on unit, we would paper the box with square inch paper and fill the box with cubic inch blocks to see whether our computations are confirmed.

The number of blankets the sophomore class can make if they have $663 to spend on supplies will be 69.

It should be noted that from the information, tje sophomore class is making blakets for the local animal shelter and the cost to make the blakets can be modeled by 0.2x² + 7.2x + 78.

Therefore, the number of blankets the sophomore class can make if they have $663 to spend on supplies will be illustrated as:

C = 0.2x² + 7.2x + 78.

0.2x² + 7.2x + 78 = 663

0.2x² + 7.2x = 663 - 78

0.2x² + 7.2x - 585 = 0

Using almighty formula, it should be noted that x will be 69.

Using the weighted mean, it is found that Trent can earn scores of at least 62 on the final exam to pass the course if he needs a "C" or better.

The complete problem is given as follows:

"Trent earns scores of 62, 86, and 80 on three chapter tests for a certain class.

His homework grade is 68 and his grade for a class project is 64.

The overall average for the course is computed as follows: the average of the three chapter tests makes up 50% of the course grade; homework accounts for 10% of the course grade; the project accounts for 20% of the course grade and the final exam accounts for 20% of the course grade.

What range of scores can Trent earn on the final exam to pass the course if he needs a "C" or better?

A "C" or better requires an overall course score of 70 or better, and 100 is the highest score that can be earned on the final exam."

The weighted mean is given by the sum of all elements in a data-set multiplied by it's weight, divided by the sum of the weights.

For this problem, we have that:

Hence his weighted mean is given by:

76 x 0.5 + 68 x 0.1 + 64 x 0.2 + 0.2x = 57.6 + 0.2x.

For a grade C, he needs a score of at least 70, hence:

57.6 + 0.2x ≥ 70.

0.2x ≥ 12.4

x ≥ 12.4/0.2

x ≥ 62.

Hence Trent can earn scores of at least 62 on the final exam to pass the course if he needs a "C" or better.

Since the maximum height of the ball above the ground is 28 ft, the ball will never reach a height of 30 ft.

To determine if the ball will ever reach a hgeight of 30 ft, we need to determine the maximum height of the ball.

Using the equation of motion, v² = u² - 2gh where

So, making h subject of the formula, we have

h = (v² - u²)/-2g

Substituting the values of the variables into the equation, we have

h = (v² - u²)/-2g

h = ((0 ft/s)² - (40 ft/s)²)/-(2 × 32 ft/s²)

h = (0 ft²/s² - 1600 ft²/s²)/-(64 ft/s²)

h = - 1600 ft²/s²/-64 ft/s²

h = 25 ft

Since the ball is released from a height of 3 ft, its maximum height above the ground is H = 3 ft + h

= 3f + 25 ft

= 28 ft

So, we see that H = 28 ft < 30 ft.
