Write the exponent for the expression. 1/9 x 1/9 x 1/9=? HELP FAST plz

Mathematics
1 answer:
spin [16.1K]3 years ago
6 0

Step-by-step explanation: To find the exponent, we look at the expression again and see how much of the same number or fraction is repeated. Since the main number is 1/9 and there are 3 fractions repeating it, the exponent is \frac{1}{9} ^3 or 1/9 to the 3rd power.

<em>Down is a formula I made!</em>

Main number: 1/9

Repeating how many times: 3

Expression: \frac{1}{9} ^3

Therefore, 1/9 to the 3rd power is 1/729.

\frac{1}{9}^3=\frac{1}{729}

<em>Note: The questioner did not ask for the answer. I wanted to add it anyway for future reasons.</em>

Marlene went shopping and bought a bunch of candy for her swim team. She bought packs of Skittles for $1.50 each and packs of M&
lord [1]

Answer:

18 Skittles

6 M&Ms

Step-by-step explanation:

Set up an equation:

Variable x = number of skittles

Variable y = number of M&Ms

1.50x + 2y = 39

x + y = 24

In the second equation, isolate a variable:

x = 24 - y

Substitute the value of x for 24 - y in the first equation:

1.50(24 - y) + 2y = 39

Use distributive property

36 - 1.5y + 2y = 39

Combine like terms

36 + 0.5y = 39

Isolate variable y:

0.5y = 3

y = 6

Substitute the value of y for 6 in the second equation:

x + 6 = 24

Isolate variable x:

x = 18

Plug these values into any equation of your choice to see if these values are correct (I'll do both equations just to prove it):

1.50(18) + 2(6) = 39

27 + 12 = 39

39 = 39

Correct

x + y = 24

18 + 6 = 24

24 = 24

Correct

Find the area of the semicircle need help asapp
sergij07 [2.7K]

Answer:

2 pi

Step-by-step explanation:

The radius is 2

The area of a circle is

A = pi r^2

We have 1/2 of a circle so

1/2 A = 1/2 pi r^2

         =1/2 pi ( 2)^2

         =1/2 pi *4

      = 2 pi

Write a pair of numbers such that the value of the 7 in the first number is 1,000 times the value of the 7 in the second number,
kirill [66]
437,000
400,307

In the second number, the 7 is moved 3 places to the right, and the 3 is moved 2 places to the right.


(The digit 4 is used here simply to make the numbers be the same overall length. It can be changed to any other digit (except 3 or 7) or removed. Digits that are not 3 or 7 can replace any of the zeros.)
