Answer:

Step-by-step explanation:

Gavin made 6 out of 15 shots, so the probability that Gavin's next shot will be  successful is

Express in exponential form 200×75​
GREYUIT [131]

Do you mean exponential form as in scientific notation or as in prime factorization.

Now matter I will do both.

As in scientific notation.

200*75

=150*100

=1.5*10000

=1.5*10^4

As in prime factorization.

200*75

=2^3*5^2*3*5^2

=2^3 * 3 * 5^4

Do the one your teacher ask for :) Hope it helps!

Gema has 4 <br> FT of wire how much wire does she need to wrap one meter of her garden?
Dmitry [639]

Answer:

3.28 feet

Step-by-step explanation:

One meter equals to 3.28 feet.

The question isn't exactly clear what Gema wants to use her wire for, because "wrap one meter" isn't correct.

You wrap something around something else...  and you can't wrap something around a meter.  You can wrap around a square meter by doing the perimeter... but then you'd need more than meter to do the perimeter of a square meter (the perimeter can be around 4 meters).

So, assuming she has a length of 1 meter to cover, she would need 3.28 feet.
