861 ÷3 show work for this problem please

Answers

Answer 1

Answer: 861 divided by 3:

How many times does 3 go into 8? 2 x 3 = 6
Subtract 6 from 8 to get a remainder of 2, and bring down 6 to get 26.

How many times does 3 go into 26? 8 x 3 = 24
Subtract 24 from 26 to get a remainder of 2, and bring down 1 to get 21.

How many times does 3 go into 21? EXACTLY 7 times. 7 x 3 = 21

Collect all numbers in bold to get…. 287!

Therefore, 861 divided by 3 = 287.

A four-sided shape with the top side labeled as 10.2 cm. The height is labeled 5 cm. A portion of the base from the perpendicular to a vertex is labeled 4 cm. The portion of the base from the perpendicular to the right vertex is 6.2 cm.What is the area of the figure?

25.5 cm2
45.5 cm2
51 cm2
56.1 cm2

Answers

The area of the figure is 51 cm².

Given that,

A four-sided figure with the top side labeled as 10.2 cm.

The height is labeled 5 cm.

This shape is a trapezium.

Total length of the base = 6.2 + 4 = 10.2 cm

Area of the figure = 10.2 × 5 = 51 cm²

Hence the required area of the figure is 51 cm².

Which of the following diagrams includes a centroid? In order: A, B, C, D

Answers

Answer:

Figure A

Step-by-step explanation:

First let's see what a centroid of a triangle is.

In a triangle there are three vertices. We draw a line segment from each vertices to the median of the opposite sides. The median of each vertices intersect in a point inside the triangle. That point is called the centroid of the triangle.

That is also called the center of gravity of the triangle.

By looking at the given figures,

The figure A is the correct answer.

There each line segments drawn from the vertices intersect the opposite side at the median. The point E is the centroid of the triangle.

Therefore, the answer is figure A.

The answer is A.......
