Answer:
so we notice that they increase by 1
each time
first slot we have all of them so
4 choices=1st slot
3 choices=2nd slot (1 was taken for 1st slot)
2 choices
1 choice
multiply
4 times 3 times 2 times 1=24
answe ris 24 ways

Answer:
From the other answer, I see that my colleague with the busted clock
interpreted your question in a different way. So I should explain
how I understand your question.
I understand you to say that both English sections meet at the
same time, all 3 math sections meet at the same time, all 3 History
sections meet at the same time, and all 4 Biology sections meet at
the same time. So our student will take the subjects in that order,
but for each period, she can choose which section to join.
If that's not the right way to understand the question, then it's definitely
too complicated for me.
Reading it MY way,
here's the solution:
English: 2 choices. For each of those . . .
Math: 3 choices. For each of those . . .
History: 3 choices. For each of those . . .
Biology: 4 choices.
Total possible different line-up of sections:
(2 x 3 x 3 x 4) = 72 different line-ups.

10 x 200 is 2000
therefore there are 200 tens .
therefore there are 200 tens .
Since 10 times 200 is 2000Therefore how many tens are in two thousand so you divide it and 2000 divided by10 will give you 200So there are 200 tens in 10 times 200

The closest measurement to the volume of hat is 84.82 in.³.
Step-by-step explanation:
Given:
The dimensions of hat are height(h) 9 inches and diameter(d) 6 inches.
Now, to find the volume of cone:
Putting the formula .
Radius(r) is not given, finding the radius:
Radius(r)=half of the diameter(d)
.
Then,
=
= (
)
=
=
= in.³
So, the volume is 84.78 in.³ .
Therefore, the closest measurement to the volume of hat is 84.82 in.³.

The answer must be '7' . Because 7 is a multiple of '7' , 7 * 1 = 7 . And 7 is also a factor of '7' because 7 has only two factors 7 and 1.

To start the question, you must figure out how much money is 4% of 175000. You solve for that by multiplying .04 by 175000.
.04 * 175000 = 7000
Now, we have to find what percent 4725 is of 7000. First, let's convert that into a fraction: 4725/7000. To find the decimal, you divide the numerator by the denominator.
4725/7000 = .675
To turn that into a percent, you move the decimal two places to the right.
.675 turns into 67.5
Your teacher asked to round it up to the nearest tenth of a percent, but the number is short enough that we do not need to round. Your answer is 67.5%.
I hoped that helped, tell me in the comments below if you need more clarification about something. :)
