A closed rectangular box whose dimensions are 8 feet by 5 feet by 3 feet has some water in it. When the box is resting on its smallest face, the water is 5 feet deep. How deep will the water be if the box is resting on its largest face? Explain your reasoning.

Answers

Answer 1

Answer:

i, 1.875 ft

ii. Since the volume of water is the same when resting on either the smallest or largest face, we we equate the expression for their volume and solve for the depth of water when the closed rectangular box is resting on its largest face.

Step-by-step explanation:

i. How deep will the water be if the box is resting on its largest face?

Since the smallest face is 5 feet by 3 feet (since they are the smallest dimensions), the volume of the 5 feet deep water is V = Ah where A = area of smallest face and h = depth of water.

V = Ah = 5 ft × 3 ft × 5 ft = 75 ft³

This is also the volume of the water when it is resting on its largest face.

Since the dimensions of the largest face are 8 feet by 5 feet (since they are the largest dimensions), then V = A'h' where A' = area of largest face and h' = depth of water when rectangular box is resting on its largest face

So, h' = V/A'

= 75 ft³/ (8 ft × 5 ft)

= 15/8 ft

= 1.875 ft

ii, Explain your reasoning.

Since the volume of the water in the closed rectangular box is always the same, which ever side we turn it to, its volume V = area of face × height. If we write this expression for both the smallest and largest face and equate them, we solve for the depth of the water when it is resting on its largest face, since, we already know the depth of water when it is resting on its smallest face.

Step-by-step explanation:

Let y represent her yearly salary

1/3 × y

1/3y

1/3y= 8220

Cross multiply

y= 8220 ×3

Vincent is building a rectangular pen for his new pet rabbit. The area of the pen is 36 square feet. The length of the fence is 5 feet longer than its width. Write the equation that can be used to model the relationship between the area of the gate and side length

Answers

Answer:

w² + 5w = 36

Step-by-step explanation:

Since the pen is a rectangle, its area, A = lw where l = length and w = width.

Since the length of the fence is 5 feet longer than its width, we have l = w + 5

So, A = lw = (w + 5)w = w² + 5w

Since A = 36 ft², we have that

36 = w² + 5w

w² + 5w = 36

Which is the required equation.

Answers

Answer:

5

Step-by-step explanation:

Both angles together will equal as they are opposite of each other

therefore

15x=16x-5

15x+5=16x

5=x

Answer:

x = 5

Step-by-step explanation:

The two angles are congruent because of the Vertical Angles Theorem. Since we now know that they're congruent, we can set up an equation to like this:

15x = 16x - 5

Now that we have an equation, we can solve for x.

First, we subtract 15x from both sides. Now we're left with an equation that should look like this:

0 = x - 5

Now we add 5 to both sides to get our solution. It should look like this.

5 = x

And there's your answer! Hope this helps.

The Science Club went on a two-day field trip. The first day the members paid $50 for transportation plus

by
HARD! [Ma

Answers

Answer:

145 + 33n

Step-by-step explanation:

Let

n = number of members in the club

Day 1:

Cost = 50 + 18n

Day 2:

Cost = 95 + 15n

Total cost two-day field trip = day 1 + day 2

= (50 + 18n) + (95 + 15n)

= 50 + 18n + 95 + 15n

= 145 + 33n

Total cost two-day field trip = 145 + 33n

An expression that represents the total cost in dollars for two days for the n members of the club is given by 145 + 33n

Solve for the value of e.
please help

Answers

Answer:

44

Step-by-step explanation:

Angles that form a straight line add up to equal 180 degrees

Hence, e + 8 + 3e - 4 = 180

                      ^ ( note that we just created an equation that we can use to

                          solve for e )

Using the equation created, we then solve for e

e + 8 + 3e - 4 = 180

step 1 combine like terms

3e + e = 4e

8 - 4 = 4

we now have 180 = 4e + 4

step 2 subtract 4 from each side

180 - 4 = 176

4 - 4 cancels out

we now have 176 = 4e

step 3 divide each side by 4

176 / 4 = 44

4e / 4 = e

we're left with e = 44

Create a polynomial function in factored form that crosses through the x-axis at -2 and touches the x-axis and turns around at 4.​

Answers

Given:

A polynomial crosses through the x-axis at -2 and touches the x-axis and turns around at 4.​

To find:

The polynomial function in factored form.

Solution:

If the graph of a polynomial intersect the x-axis at [tex]x=a[/tex], then [tex](x-a)[/tex] is a factor of the polynomial.

If the graph of a polynomial touches the x-axis at [tex]x=b[/tex], then [tex](x-b)[/tex] is a factor of the polynomial with multiplicity 2. In other words [tex](x-b)^2[/tex] is the factor of the polynomial.

It is given that the polynomial crosses through the x-axis at -2. So, [tex](x+2)[/tex] is a factor of required polynomial.

It is given that the polynomial touches the x-axis and turns around at 4. So, [tex](x-4)^2[/tex] is a factor of required polynomial.

Now, the required polynomial is:

[tex]P(x)=(x+2)(x-4)^2[/tex]

Therefore, the required polynomial is [tex]P(x)=(x+2)(x-4)^2[/tex].
