Fraction: 9/10000

Decimal: .0009

Answer : The decimal and fraction form of 0.09 % is, 0.0009 and \frac{9}{10000}  respectively.

Step-by-step explanation :

Decimal numbers are not considered as integers. They are rounded off to write an integer.

Fraction is present in the form of \frac{p}{q} where q\neq 0

To remove decimal, we divide the number by 10^n where, n = number of decimal places.

As we are given:

0.09\%

Converting this into decimal form, we get:

\Rightarrow 0.09\%=\frac{0.09}{100}=0.0009

Converting this into fractional form, we get:

\Rightarrow 0.09\%=\frac{0.09}{100}=\frac{9}{10000}

Thus, the decimal and fraction form of 0.09 % is, 0.0009 and \frac{9}{10000}  respectively.

A jar of marbles contains the following: two purple marbles, four white marbles, three blue marbles, and two green marbles. What
Llana [10]

Answer:

4/11

Step-by-step explanation:

Total number of marbles = 2(purple) + 4(white) + 3(blue) + 2(green)

                                          = 11

Number of white marbles = 4

Probability of selecting a white marble =

         number of white marbles/total number of marbles in the jar

         = 4/11

loris [4]

Answer:

7i) 140  7ii) 80  7iii) 60  8i) isosceles  8ii) 74  8iii) 60  8iv) 46 degrees  9i) 56  

9ii) 80  9iii) 62  10) Angle c is 64 degrees. Angle d is 26 degrees

Step-by-step explanation:

7i) Add up all the interior angles. Since the triangle is isosceles, there are two 70 degree angles. The exterior angle is equal to the two 70 degree angles together, or 140 degrees.

7ii) Add up all the interior angles. Since the triangle is isosceles, there are two 40 degree angles. The exterior angle is equal to the two 40 degree angles together, or 80 degrees.

7iii) Add up all the interior angles. Since the left triangle is isosceles, there are two 30 degree angles. The exterior angle is equal to the two 30 degrees angles together, or 60 degrees.

8i) This is an isosceles triangle because two of the sides are the same length.

8ii) Since the triangle is isosceles, there are two 74 degree angles, and angle BDC is one of them.

8iii) Since the triangle is equilateral, all of the angles equal 60 degrees. This means that angle DAB is 60 degrees.

8iv) Add together 60 degrees from the equilateral and 74 degrees from the isosceles triangle and subtract that sum from 180. 180 - (60 + 74) = 46 degrees.

9i) Angles x and 56 are consecutive interior angles, which means they are the same measure.

9ii) Since the triangle is isosceles, two of the angles are 50 degrees, so subtract 100 from 180 to find the other angle. 180 - 100 = 80 Angles 80 and x are alternate interior angles, which means they are the same measure.

9iii) Angle is has a measure of 62 degrees because the two triangles are the same except for the size, which doesn't matter.

10) Since the left triangle is isosceles, there are two 58 degree angles, so subtract the sum of the two angles from 180. 180 - 116 = 64 degrees  Looking at the triangle on the right, add together the 64 and 90 degree angles and subtract from 180 to find the measure of angle d. 180 - 154 = 26 degrees

Rewrite the expression in the form 6^n 6^-6/6^-5
oee [108]

Answer:

6^-1

Step-by-step explanation:

6^-6 - (-5) = 6^(-6 + 5) = 6^(-1)

A lot of things are going on in this question. Notice how the 5 is handled. It starts off in the denominator as - 5 and when brought to the numerator it becomes -(-5) which makes it + 5.

The answer is then easy. It is 6^(-6 + 5) = 6^-1

You could give the answer as 1/6 but that is not what the question says.
