What is 19% of 72? I NEED TO KNOW HOW YOU GOT THE ANSWER TO!!

Answers

Answer 1
Answer: First you must multiply the number by the percent. (19*27= 513)
Then you divide the answer by 100, or move decimal two places to the left. (513/100= 5.13)
Then round to the nearest whole number (5.13 is approximately 5)
Therefore 19%of 27 = 5

Lusia ran 3 2/3 kilometers in 1/3 of an hour. If speed is distance over time, calculate lusia's speed.

Answers

In the question, they give you the formula for speed...

speed = distance / time

They also give you the distance and the time, so all we have to do is stick them into the equation...

speed =  3 2/3 Km / 1/3 hour
speed = 3 2/3 / 1/3

To divide the fractions, first we need to convert 3 2/3 into an improper fraction

3 2/3 = 11/3

now we multiply 11/3 x the reciprocal of the divisor 1/3.  The reciprocal just means flip the numerator and denominator

speed = 11/3 x 3/1
speed = 33/3
speed = 11 Km/hour

How do you do this I really need help!?!

How To Solve:

Basically what the question is asking is to figure out 2 number that can be added to form 12 then the 2 same numbers to multiply to form 36.

----------------------------------------

Answer:

6 + 6 = 12

6 x 6 = 36

----------------------------------------

Hope This Helps :)

6x6=36 and 6+6=12 so the answers 6

The rectangles are similar.What scale factor was applied to the first rectangle to get the resulting image?

Enter your answer as a decimal in the box.

The image is a rectangle that says 6 then a smaller rectangle that says 1.5

Answers

the answer is .25 hope that helps

Answer:

The answer is 0.25! :)

Step-by-step explanation:

To find the scale factor, you have to do division of the shorter sides of the first and second rectangle. 1.5/6 which equals 0.25.

Hope this helps! <3

1.Find the exact solution to the equation.(2 points)

log base four of x equals two.

Answers

Answer:

x = 16

Step-by-step explanation:

The equation is \log_(4) x = 2

Now, converting this logarithmic equation into exponential equation, we get

x = 4^(2) = 16(Answer)

Alternate solution:

Given,\log_(4) x = 2

\log_(4)x = 2\log_(4)4

{Since, we know that \log_(a)a = 1}

\log_(4)x = \log_(4)4^(2) = \log_(4)16

{Since, a\log b = \log b^(a) is a property of logarithm}

Cancelling log from both sides we get,

⇒ x = 16 (Answer)

Answer:

x = 8^4

Step-by-step explanation:

hey there,

< Here is what is given:

_(8) x=4

There's actually a lot of different ways you can remember this but the way I remember this is x is equal to 2nd to the power of last.

So 8 is the 2nd (since log is first), 4 is last (very last thing in the equation).

x = 8^4

You can use any of your own ways to remember this, but this is just my personal way. :) >

In how many ways can you choose 2 side dishes out of 8

Answers

The first choice can be any one of the 8 side dishes.
               For each of these . . .
The 2nd choice can be any one of the remaining 7.

     Total number of ways to pick 2 out of 8 = (8 x 7) = 56 ways .

BUT ...

That doesn't mean you can get 56 different sets of 2 side dishes.

For each different pair, there are 2 ways to choose them . . .
(first A then B), and (first B then A).  Either way, you wind up with (A and B).

So yes, there are 56 different 'WAYS' to choose 2 out of 8.
But there are only 28 different possible results, and 2 'ways'
to get each result.
I'm about 75% confident in my answer. Saying that, I mean that i'm not always right. I think it's 73
