5. Quarter past 2 is 15 minutes past 2 so it is 2:15
2:15 plus 30 minutes would be 2:45

6. The change you get when you buy something is the amount you pay with minus the cost. If you subtract $2.80 from $5 you get $2.20.
5 - 2.80 = 2.20
It could be 2 one-dollar bill and 2 dimes (1 dime = 10 cents).

What is the Greatest Common Factor of x^4 and x^3?

hammer [34]

Judging by the question I noticed that the two both share x^3 in common. You can divide x^4 by x^3 and get x as a result, and x^3 can still divide into itself.

Thus your answer should be C, x^3

Andrej [43]

Answer: 210

Step-by-step explanation:

We know that the number of combinations of n things taken r at a time is given by :-

$C(n,r)=\dfrac{n!}{r!(n-r)!}$

So, number of ways to select 3 plants out of 7 = $C(7,3)=\dfrac{7!}{3!4!}=\dfrac{7\times6\times5\times4!}{6\times 4!}=7\times5=35$

Also number of ways to arrange them in 3 positions = 3! = 6

Now , total number of arrangements with 1 plant in each spot = (number of ways to select 3 plants out of 7) x (number of ways to arrange them in 3 positions)

= 35 x 6

=210

Hence, required number of ways = 210

ratelena [41]

Yes it is equivalent because you need to isolate the y so divide by 5 on both sides and 23 divided by 5 is 4.6
