Nolan rides his bike 63 miles in 270 minutes. What is his average speed in miles per hour?

Mathematics

boyakko [2]3 years ago

Here, to find the average rate of change, you would simply divide 270 by 63. And when that is done, you would get a long decimal. 4.285714285714286

And since you obviously can't put in such a long decimal as your answer, you would round it instead. Once rounded, you would end up with 4.29 (because the number after 8 is five, which rounds up, which would turn the 8 to 9.)

Ally collects stickers as a hobby. She gives her sisters of her stickers.
sertanlavr [38]

Answer:

\frac{16}{25}

Step-by-step explanation:

Ally gives her sister = 1/5 stickers

Ally gives her cousin = 1/5 of the remainder stickers

Assume Number of sticker Ali has = 1

Remainder after giving stickers to her sister = 1 - 1/5 = 4/5

Number of stickers she gave her sister = \frac{1}{5}\times\frac{4}{5}

         =\frac{4}{25}

Sticker she has = 1-\frac{1}{5}-\frac{4}{25}

=\frac{25-5-4}{25}

=\frac{16}{25}

Sticker left with Ally is equal to \frac{16}{25}.

Is it possible for the area of a figure to change after it is translated? Explain.
Mariulka [41]
It is not possible for the area to change with a translation because translations are simply movements. They are not changing anything about the object's form, like something such as scaling does.

ch4aika [34]

Answer:

x=2,x=7

Step-by-step explanation:

-3x^2+27x=42

x^2-9x+14=0

x*(xi2)-7(x-2)=0

(x-2)*(x-7)=0

x-2=0

x-7=0

x=2

x=7
