Mathematics
1 answer:
andrey2020 [161]2 years ago
5 0

Answer:

Step-by-step explanation:

I am not clear your question.

5^(-2) / ( 5^(-3) * 5^(4))

When base is equal at multifaction index should be add.

ie. (-3)  + 4 =1

5^(-2) / ( 5^((-3) +4))

5^(-2) / ( 5^(1))

When base is equal at division index should be substract.

5^(-2) / ( 5^(1))

5^((-2 )+ (-1) )

5^(-3)

We know a^(-2)= 1/ a^2

1/ 5^(3)

M = ($6/hr)h

If Crystal works 2 hrs 45 min, she will earn

M(2  3/4 hrs) = ($6/hr)(2  3/4 hrs), or

                      = $66/4  = $16.50

Carolina leaves her house and walks 6 blocks she turns and heads east 8 blocks until she reaches matties house what is the short
s2008m [1.1K]

Answer:

10 blocks

Step-by-step explanation:

Given

First = 6\ blocks

Second = 8\ blocks east

Required

Determine the shortest possible distance

To better explain my solution, I've added an attachment that illustrates her movement.

Using the attachment as a point of reference, the shortest distance is calculated by calculating the length of the hypotenuse using Pythagoras theorem.

So, we have:

x^2 = 6^2 + 8^2

x^2 = 36 + 64

x^2 =100

Take positive square root of both sides

x = \sqrt{ 100

x = 10

Lenny rolls two number cubes. What is the probability that the sum of the numbers Lenny rolls is either 4 or 7?
Mashutka [201]

Probability of an event =


(number of ways the event can happen) / (total number of possible outcomes) .


Well, the total number of possible outcomes is easy. It's


(6 possibilities for the first cube) x (6 possibilities for the 2nd cube)


= 36 total possible ways for two cubes to roll.


Now, how many of those possibilities show either 4 or 7 ?


Well, here's how a 4 can come up:


1 . . . 3

2 . . . 2

3 . . . 1


and here's how a 7 can come up:


1 . . . 6

2 . . . 5

3 . . . 4

4 . . . 3

5 . . . 2

6 . . . 1 .


So there are 9 ways all together for Lenny to be successful.


The probability is (9/36) .


That's 1/4 , or 25% .
