Answer:

Here

Step-by-step explanation:

By converting the ratios to decimal numbers or percentages, you can compare them on a level field. Divide the numerator by the denominator of one ratio. For example, if the ratio is 4/7, then divide 4 by 7. This will yield a decimal number between zero and one.

What is 1 2/3 to the 3rd power

hammer [34]

Answer:

$2\frac{7}{9}$

Step-by-step explanation:

In order to get the answer to this question you must change the mixed number into a improper fraction then multiply the improper fraction as many times as it's exponent.

$1\frac{2}{3} ^3$

Turn the mixed number into a improper fraction:

$1\frac{2}{3} =\frac{5}{3}$

$=\frac{5}{3}^3$

$\frac{5}{3} ^3=\frac{5}{3} \times\frac{5}{3} \times\frac{5}{3}$

Now multiply:

$\frac{5}{3} \times\frac{5}{3} =\frac{25}{9}$

$\frac{25}{9} \times\frac{5}{3} =\frac{75}{27}$

Turn the improper fraction into a mixed number:

$\frac{75}{27} =2\frac{7}{9}$

$=2\frac{7}{9}$

Hope this helps.

Please help me im using my all out attack

TiliK225 [7]

Answer:

for the first answer your answer was correct, it was the second answer that was wrong. So the first answer is 2 3/4. The second answer would be 81 centimeters because it grew that much.

Step-by-step explanation:

To find the first answer add the starting height and ending height. To find how much it grew convert the total ending height of the tree to cm by multiply by 100, so 275. Then subtract 356 by 275 because you are finding out how much it grew. Take away 275 from 356 and you get 81

What is the solution to the equation? 18y - 30 - 7y = 25

kirza4 [7]

Answer:

Step-by-step explanation:

18y -30 -7y =25

solution

18y -30 -7y =25

so we take like terms that is unknown to unknown whole number to whole number or you can put it this way to remember(brothers go to brothers are the ones with an alphabet , sisters go to sisters they are the ones without an alphabet numbers)......okay lets continue

18y -7y=25+30

when a negative is crossing an equal sign it turns positive and vice versa

so lets solve

11y=55

the one with the unknown will divide

11y/11=y

you cant say 1y its wrong in maths you can say in another subject but not maths....okay...so we say y the 1 is invisible but you can say 2y ,3y etc

Then 55/11=5

so y=5

Thats the correct answer....

Give an example of a defined term and explain what is defined.

masha68 [24]

A defined terms can be combined and form with the undefined terms to complete the definition of the term. A vertex for example, it is form when two lines are meet to each other or there would be an intersection of two lines. I hope you are satisfied with my answer and feel free to ask for more

The population of a town increased by 10% per year in 2009, 2010, and 2011. If the population of the town at the beginning of 20

sattari [20]

Assuming that the population follows an exponential function, the it will take the form:
y=a(bˣ)
where:
a=initial value
b=growth factor
x=time
thus plugging our values in the equation we get:
y=40000(1.1ˣ)
thus the population in 2011 when t=3 will be:
y=40000(1.1³)
y=53240
