Can somebody please help me

Answer:

Step-by-step explanation:

In each case, you can use the given formula to find the surface area. The area of the triangular base (B) is ...

  A = 1/2bh

where b is the base of the triangle, and h is the height of the triangle perpendicular to that base.

You will notice that B is multiplied by 2 in the area formula, because there is a triangular base at either end of the prism. That means we can save some work by not multiplying by 1/2, and then by 2.

__

For figures 1, 3, 4, the triangle is a right triangle, so the base and height make up two of the three sides of it. The perimeter is finished by adding the length of the hypotenuse. That sum is then multiplied by the "height" of the prism (distance between bases) to find the lateral area as part of the area formula (Ph).

In figure 3, the triangle is equilateral, so the perimeter is not the sum of the base and height and a third side. In the attached spreadsheet, we have used a value "rest of perimeter" to make the sum be the right value for use in computing the value of Ph. For figure 3, that is 6+6-5.2=6.8. Then the sum 6 +5.2 +6.8 is 18, the proper perimeter for that figure.

__

The idea here is to let a spreadsheet do the tedious work of applying the same formula to different sets of numbers. The areas are ...

__

By way of example, we can "show work" for problem 1:

1. S = Ph +2B

  S = (4 +3 +5)(8) +2(1/2)(4)(3) = 12(8) +12 = 96 +12 = 108 . . . cm^2

Answer:

$11390.30

Step-by-step explanation:

Discount

12916 x 0.15 = 1937.4

Discounted price

12916 - 1937.4 = 10978.6

Tax of 3 and 3/4 percent which I think is 0.0375

10978.6 x 0.0375 = 411.6975

Total

10978.6 + 411.6975 = $11390.2975

The removable discontinuity is at negative 6 and 6. Then the correct option is B.

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

The function is given as

[tex]f\rm (x) =\rm \dfrac{x^2-36}{x^3-36x}[/tex]

The expression can be written as

[tex]f\rm (x) =\rm \dfrac{x^2-36}{x(x^2-36)}[/tex]

[tex]f\rm (x) = \dfrac{1}{x}[/tex]

The non-removable discontinuity is x = 0.

Step-by-step explanation:

all shapes need to have all angles to add up to 180 but this triangle adds up to 170

Answer: The measure of the missing angle is 115∘.

Step-by-step explanation: To find missing interior angles, you have to add the two angles that are known and see how much they add up.  The work is done below:

40∘ + 75∘ = 115∘.

In order to find out the missing interior angle, we have to subtract 115∘ from 180∘ to find that angle:

180∘ - 115∘ = 65∘, which is the missing angle that is inside the triangle.

Now, you're probably wondering how any of this has to do with finding the angle that has a ? on it.  Well, us finding the missing interior angle inside of the triangle is what's going to help us find that angle with a ? on it.  To find that angle, you need to subtract 65∘ from 180∘ to find the angle that you need:

180∘ - 65∘ = 115∘.

Therefore, 115∘ is your answer.

Answer:

Its a graph. Each of those black dots represent a person answering the survey. For example: 2 people only chose 3 letters, 1 person only chose 4 letters, 2 people chose 5 letters, and so on. So the answer is 10. Hope this helps!

Step-by-step explanation:

Answer:

To increase a price, add the percentage you wish to increase it by to 100%, convert the percentage into a decimal by dividing by 100, then multiply this by the original price.

To decrease a price, subtract the percentage you wish to decrease it by from 100%, convert the percentage into a decimal by dividing by 100, then multiply this by the original price.

-------------------------------------------------------------------------------------------------

100% represents the original price.

Therefore, 100% = $599.99

A 20% discount means that the price is now 80% of the original price,
as 100% - 20% = 80%

To find 80% of the original price, convert 80% to a decimal and multiply it by the original price:

80% = 80/100 = 0.8

Therefore, 80% of $599.99 = 0.8 x $599.99

                                              = $479.992

Finally, we need to apply a sales tax of 6%.  We can do this in 2 ways:

Way 1

Work out 6% of the discounted price, then add this to the discounted price to find the final price:

Sales tax = 6% of $479.992

               = 0.06 x $479.992

               = $28.79952

Final price = discounted price + sales tax

                  = $479.992 + $28.79952

                  = $508.79 (nearest cent)

Way 2

We need to increase the discounted price of $479.992 by 6%.  Therefore, the final price will be 106% of the discounted price as
100% + 6% = 106%

Final price = 106% of discounted price

                  = 1.06 x $479.992

                  = $508.79 (nearest cent)

Step-by-step explanation:

you multiply the length and the width

Answer:

3. 40. 4. 132

Step-by-step explanation:

You find the area by doing base x height so 10 x 4 is 40 and 12 x 11 is 132.

This is a practical exercise. However, the following definitions and equations will help you to arrive at the density of the objects you will put on the tray.

Population density is defined as the number of people (in this case) items (N)/area of space that they occupy. (A)

Note that the area to be occupied by the items you will put on the Square Tray is 10 X 10  = 100inches.

Assuming the number of items that you put on the tray (that is total number of muffins, cookies, biscuits etc) equals 50,

The Density will be = 50/100

= 0.5 objects/In
