Find the surface area of the square pyramid

Find The Surface Area Of The Square Pyramid

Answers

Answer 1

Answer:

The surface area of the square pyramid is 40 units².

Step-by-step explanation:

As we know that the total surface area of a square pyramid can be obtained by identifying the length 'b' of its base and its slant height 's' by using the formula:

[tex]A=2bs+b^2[/tex]

From the figure, it is clear that

length of its base = 'b' = 4slant height = 's' = 3

substituting the values in the formula

[tex]A=2bs+b^2[/tex]

[tex]A=2\left(4\right)\left(3\right)+\left(4\right)^2[/tex]

    [tex]=2\left(4\right)\left(3\right)+16[/tex]

    [tex]=40[/tex]

Therefore, the surface area of the square pyramid is 40 units².

Which is SMALLER, -6.3 or -6.1?

i believe the answer is -6.3

my explanation is because -6.3 is less than -6.1 so technically it makes it smaller. if you were to add to -6.3 you would get -6.1 on the x axis.

Which line has a constant of proportionality between yyy and xxx of 555?

Answers

The line that has a constant of proportionality of 5 between y and x is: line A.

How to Find the Constant of Proportionality?

The constant of proportionality of a proportional relationship is found using the formula:

Constant of proportionality, k = y/x, where (x, y) is any point on the proportional graph.

Find the constant of proportionality for line A using a point, (1, 5):

Constant of proportionality, k = y/x = 5/1 = 5

Find the constant of proportionality for line B using a point, (3, 5):

Constant of proportionality, k = y/x = 5/3

Find the constant of proportionality for line C using a point, (3, 2):

Constant of proportionality, k = y/x = 2/3

Therefore, the line that has a constant of proportionality of 5 between y and x is: line A.

Meredith
says that 15.17 is greater than 15.8
because 17 is greater than 8. Do you
agree? Explain your reasoning

Answers

Answer:

No

Step-by-step explanation:

Because in the number 15.8, it is equal to 15.80. 80 is more than 17.

15.17 is not greater than 15.8. Meredith statement is wrong.

What is Number system?

A number system is defined as the representation of numbers by using digits or other symbols in a consistent manner.

We need to compare both the numbers 15.17 and 15.80.

For comparing two number we need to check the integer part and decimal part.

The integer part  is same for both the numbers. so let us move towards decimal part. in tenth place 15.17 has 1 and for 15.80 it has 8.

We know that 8 is greater than 1.

Hence 15.8 is greater than 15.17. Merediths answer is wrong.

Answer:

No solution

Infinitely many solutions

One solution

Step-by-step explanation:

The first expression:

           -2(3x  - 1) = -6x -1

  Expand the parentheses;

           -6x + 2  = -6x -1

             -6x + (-6x) = -1 -2

                 0 = -3

This problem has no solutions

Second expression:

          2(3x-1) = 6x -2

  Expand the parentheses;

          6x - 2  = 6x -2

           6x -6x = -2 + 2

             0 = 0

This problem has infinitely many solutions

Third expression:

2(3x - 1) = -6x -2

    Expand the parentheses;

       6x -2 = -6x - 2

        6x + 6x = -2 + 2

           12x = 0

               x  = 0

This equation has only one solution

Adam is building a rectangular planter without a top. The planter will be 14 cm wide, 20 cm long, and 30 cm high. How much wood is needed to make the bottom and sides of the planter? (show working as well)

Answers

Answer: The surface area of the planter will be 120.5 square feet.

Step-by-step explanation:  in our shape, we will have 5 sides. The base and the four sides going up from each edge of the base.

The base will be 7 x 5 = 35 square feet.

The front and back side will each be 7 x 0.75 = 5.25 square feet.

The left and right side will each be 5 x 0.75 = 3.75 square feet.

If we add up the 5 faces we get:

35 + 5.25 + 5.25 + 3.75 + 3.75 = 120.5 square feet

What is the value of m? Please provide an explanation, thanks!

Answers

Answer:

∠m=124°

Explanation:

There are a few different ways that you could go about this but the simplest way is to first notice that Angle n is congruent to the angle above it. That tells us that n = 56 degrees. Because angle m and n are supplementary angles their sum needs to add up to 180. So if we subtract 56 from 180 we get 124 degrees, and there is your answer.

Hope this helps :)

Answers

Answer:

T, S, U

Step-by-step explanation:

Answer:

U S T

Step-by-step explanation:

The largest angle is going to be opposite the longest side. It stands to reason that the two arms that define the enclosed angle (t) have to have their arms stretched further away from each other in order to accommodate T. So T is the largest angle.

By a similar line of reasoning, the second largest angle is opposite the second largest side. S is the second largest angle.

The smallest angle is opposite the smallest side.
