Find the surface area of the triangular pyramid.

a triangular pyramid - the base has side length 2.5 inches and height 2.2 inches and each face has height 5 inches

Answers

Answer 1

Answer:

31.25 in²

Step-by-step explanation:

Surface area of triangular pyramid

Perimeter, P = 4s = 4 * 2.5 = 10 inches

Lateral surface area = 0.5 * P * height = 0.5 * 10 * 5 = 25 inch²

The base area = s² = 2.5² = 6.25 inch²

Hence, surface are ao triangular pyramid ;

Lateral surface area + base area

= 25 inches + 6.25 inch²

= 31.25 in²

I will do it in a way that can solve all these kinds of problem.

Of course, you can just substitute every possible answer in and see which one has the highest y value.

BUT I'm going to do this question by completing the square.

First organize the equation by decreasing degrees.

y=-16t^2+32t

Now factor out a -16 to make the x variable have no coefficient.

y=-16(t^2-2t)

Now complete the square.

y=-16(t-1)^2+16

By this if you graph it its the parent graph y=x^2, its a reflection over x axis by the negative sign at the beginning, then a vertical stretch by 16, and then go to the right by 1 then up by 16. This meant that the vertex is (0,0) go right 1 and up 16.

The vertex or the highest point of the graph is point (1,16) This also meant that its after 1 second at 16 feet height. The answer is B.

A comet passes Earth every 70 years. Another comet passes Earth
every 75 years. If both comets pass Earth this year, how many years
will it be before they both pass Earth on the same year again?

Answers

Answer:

1,050 years

Step-by-step explanation:

A comet passes Earth every 70 years.

Another comet passes Earth

every 75 years

If both comets pass Earth this year, how many years

will it be before they both pass Earth on the same year again?

Find the lowest common multiple of 70 years and 75 years

70 years = 70, 140, 210 , 280, 350, 420, 490, 560, 630, 700, 770, 840, 910, 980, 1050, 1120, 1190, 1260,

75 years = 75, 150, 225 , 300, 375, 450, 525, 600, 675, 750, 825, 900, 975, 1050, 1125, 1200, 1275, 1350

Lowest common multiple of 70 years and 75 years is 1,050 years

Therefore,

If both comets pass Earth this year, they both pass Earth the same year again in the next 1,050 years

What percentage of the pieces was he missing if he had 250 puzzle pieces and was missing 15 What percentage of the pieces was he missing

Answers

Answer:

Percentage of missed puzzle pieces = 6%

Step-by-step explanation:

Total number of puzzle pieces = 250

Missed puzzle pieces = 15

Percentage of the missing puzzle pieces = [tex]\frac{\text{Missed puzzle pieces}}{\text{Total number of puzzle pieces}}\times 100[/tex]

= [tex]\frac{15}{250}\times 100[/tex]

= 15 × 0.4

= 6%

Therefore, percentage of missed puzzle pieces = 6%

solve the system of equations by adding. checking your answer
2x+2y=2
3x-2y=43
the solution of the system is ( , )​

Answers

Answer:

Step-by-step explanation:

This is very easy, because the coefficients of the y terms are 2 and -2. You can easily eliminate the y terms by adding the equations together:

2x + 2y = 2

3x - 2y = 43

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

5x + 0y = 45,  so x = 9

Use the value of x to solve for  y:

2(9) + 2y = 2

y = -8

(x,y) = (2, -8)

Peter determined the area, in square miles, of a piece of land using his calculator. The result of his calculation is displayed on his calculator in scientific notation as 7.4e – 4.
Which statement is true of the area of the piece of land?

Answers

Answer:

The true statement of the area of the piece of land is;

(C) It is between 0.0007 and 0.007 square mile

Step-by-step explanation:

Using scientific notation, we have the value of a measurement presented as follows;

c × 10ⁿ = ce±n

Where;

c = The coefficient number, less than 10

en = 1 × 10⁺ⁿ

e-n = 1 × 10⁻ⁿ

Therefore, the given number, 7.4 e - 4, can be expressed as follows;

7.4 e - 4 = 7.4 × 10⁻⁴ = 0.00074

0.00074 ≈ 0.0007 and we have;

0.0007 < 0.00074 < 0.007

The correct option is therefore that it is between 0.0007 and 0.007 square mile

The statement that is true of the area of the piece of land is that it is between 0.000074 and 0.00074

The standard form for writing scientific notation is given as A * 10^n

Given the result of his calculation displayed on his calculator in scientific notation as 7.4e^-4.

Writing this as a standard value will give:

7.4e^-4 = 0.00074 (Note that the decimal point was shifted back in four placs

Hence the statement that is true of the area of the piece of land is that it is between 0.000074 and 0.00074

Step-by-step explanation:

Since the order is important, as there are different roles, a permutation is used, hence option B is correct.

When to use the combination and the permutation formula?If the order in which the options are taken is important, permutation is used.Otherwise, if the order in which the options are taken is not important, combination is used.

In this problem:

If the order is LeBron and Giannis, LeBron is the co-captain and Giannis is the captain.If it is Giannis and LeBron, Giannis is the co-captain and LeBron is the captain.

Hence the order is important, which means that it is a permutation.

Answer:

y = 11

Step-by-step explanation:

4y = 40 + 4

4(r + 1) = 40 + 4

4(r) + 4(1) = 40 + 4

4r + 4 = 40 + 4

4r + 4 = 44

4r + 4 - 4 = 44 - 4

4r = 40

4r ÷ 4 = 40 ÷ 4

r = 10

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

y = r + 1

y = (10) + 1

y = 11
