A triangular pyramid has lateral faces with bases of 8 meters and heights of 10
meters. The area of the base of the pyramid is 27.7 square meters.
What is the surface area of the pyramid?
The surface area of the pyramid is
square meters.

Answers

Answer 1

Answer:

147.7 m²

Step-by-step explanation:

Area of the triangular faces = 1/2 × base × height

A triangular pyramid has lateral faces with bases of 8 meters and heights of 10 meters.

Hence: 1/2 × 8 × 10 = 40 m²

A triangle has 3 faces, hence, area of the 3 faces = 3 × 40 m²

= 120m²

The area of the base of the pyramid is 27.7 square meters.

Hence, the surface area of the pyramid is calculated as:

Area of the 3 lateral faces of the pyramid + Base area

= 120m² + 27.7 m²

= 147.7 m²

The surface area of the pyramid is 147.7 square meters.

Step-by-step explanation:

Convenience sampling can be understood as a type of sampling that occurs when there is high availability of the population to be investigated.

This method incurs several criticisms because it is not a sampling method that reflects the reality of a population, but convenience sampling can be advantageous due to the speed with which the data are collected and the research initiated, thus being a method recommended for pilot tests.

Raja drove from A to B at an average speed of 50mph

The distance between A to B is 10 Miles

Raja took 30 minutes to drive from A to C

He drove from A to C at an average speed of 62mph

Work out Raja’s average speed as he drove from B to C

Answers

Answer:

44.7

Step-by-step explanation:

Speed = distance / time

speed from distance a to b = 50 = 10 / time

time = 10/50 = 12 minutes

Speed from a to c = 62 = distance / 30 minutes

distance = 62 x 0.5 = 31 m

diatance from b to c = 31 - 10 = 21

time = 30 - 12 = 28 minutes

speed = 21 / 28 minutes

31 / 0.47

The first group of just two sides is 13*11 = 143, and for both sides 286 in^2

Then for the second group, 13*10 = 130, and for four sides, 520 in^2

help me​

Answers

Answer:

Width of the rug = x feet

Length of the rug = (x + 4) feet

Step-by-step explanation:

Let

Width of the rug = x feet

The rug is 4 feet longer than it is wide.

Length of the rug = (x + 4) feet

For instance, to find the area of the rug

Area of a rectangular rug = length × width

= (x + 4) * x

= x² + 4x

Area of a rectangular rug = x² + 4x

To find the perimeter of the rug

Perimeter of the rectangular rug = 2(length + width)

= 2{(x + 4) + x}

= 2(x + 4 + x)

= 2(2x + 4)

= 4x + 8

Perimeter of the rectangular rug = 4x + 8

The ratio of mass of kangaroo to the mass of a penguin is 7:2. The kangaroo weighs 56 kg. What is the mass of penguin?

Answers

Answer: 16

Step-by-step explanation:

I think my answer is correct because, if kangaroo is 56  kg and the ration kangaroo to penguin  was 7:2 I think we just have to divide 7 by 56. And 56 divided by 7 equals=8. and Since the pengiuins ration is 2 we just have to multiply 8 and 2. And 8 times 2 equals 16.

What signifies it to me, whether he who does it is a king or a common man; my countryman or not my countryman; whether it be done by an individual villain, or an army of them?

He asks what difference it makes who his opponent is or what crime he commits.

However, he also believes that if a person or group commits severe crimes against him, that party should be punished, no matter who they are.Paine's claim that no amount of money could induce him to wage war is self-serving, but he argues rightly that anyone who threatens his safety or the safety of his family should be punished.All the treasures of the world could not have induced me to support an offensive war, for it is murder; but if a thief threatens to kill me or my family should I suffer it?
