How do you turn a decimal into a fraction?

Answers

ok so remember
0.1=tenth=1/10
0.01=hundreth=1/100
0.001=thousantht=1/1000
and so on
you just count how many decimal places it is

example

0.3=3/10

0.04=4/1000

0.0343=343/10000

In order to turn a fraction into a decimal, you simply have to complete the fraction by dividing the numerator (the number on top of the fraction) by the denominator (the number on the bottom of the fraction).

For example, say we have the fraction $(1)/(5)$ . All we have to do to convert it into a decimal is divide 1 by 5.

1 / 5 = 0.2

So, the fraction $(1)/(5)$ written as a decimal would be 0.2.

Which polynomial is in standard form? A) 5x6 − 6x8 + 7x9 + 9 B) x2 + 2x3 − 3x4 + 3x5 C) 3x3 − 5x2 + 7x4 + 9x3 D) 2x5 − 6x3 + 3x2 − x

Answers

Answer: choice D

2x^5 - 6x^3 + 3x^2 - x

Explanation:

Polynomials in standard form always have the exponents decrease (ie go from largest to smallest) when we read from left to right. For choice D, the exponents from left to right are: 5, 3, 2, 1. This is decreasing order. The other answer choices do not have the exponents in decreasing order. The degree of the polynomial in choice D is a 5th degree polynomial since 5 is the largest exponent.

A circle has a sector with area 27pi and central angle of 120 degrees. What is the area of the circle

Answers

Answer:

81 π

Step-by-step explanation:

The total central angle for a circle is 360 degrees.

In the question the sector with angle 120 degrees has area 27π.

So the circle can be considered as a combination of 3 sectors having angle 120 degrees each. Refer to the figure below.

Thus area of the circle will be three times of the area of the sector.

Area = 3 × 27π = 81π

Answer:

Step-by-step explanation:

81pi
