a plant cell is 0.00001267 meter wide.How is this number written in scientific notation?

Answers

Answer 1

Answer: The answer is 0.00001267 m = 1.267 * 10^(-5) m. In scientific notation, the number is written as two factors - a number m from 0-10 and 10 raised to the n power: m x 10^n. 0.00001267 m = 1.267 x 0.00001 m. 0.00001 m = (0.1)^5 = 10^(-5). So: 0.00001267 m = 1.267 x 0.00001 m = 1.267 x (0.1)^5 m = 1.267 x 10^(-5) m.

Joan is building a sandbox in the shape of a regular pentagon. The perimeter of the pentagon is 35y4 – 65x3 inches. What is the length of one side of the sandbox?

Answers

The perimeter of the pentagon is
35y⁴ – 65x³

We let s as the length of one side of the sandbox. Since the sandbox is a pentagon, it's perimeter is given by
P = 5s
5s = 35y⁴ – 65x³
Solving for s
5s = 5(7y⁴ - 13x³)
s = 7y⁴ - 13x³

The length of one side is 7y⁴ - 13x³.

Mr. Norris wrote a doubles fact It has a greater than 6. The numbers that he sum than 6. What fact added are each less might he have written?

Answers

Answer:

we have given that

1) wrote a doubles that is greater than 6

to find out

What added each less might he have written

so we can say it could be

4 + 4 = 8

because number is added is less than 6 and sum greater than 6

and other is

5 + 5 = 10

so answer is 4 + 4 and 5 + 5

The sum of the measure of the interior angles of a polygon is 2160°. What polygon is it? 14-gon 12-gon 13-gon 15-gon

Answers

Answer:

It is a 14-gon.

Step-by-step explanation:

Sum of internal angles of an n sided polygon = 180(n - 2) degrees.

2160 = 180(n - 2)

2160 = 180n - 360

`180n = 2520

n = 2520 / 180

= 14.

Answer:

12-gon
