66 x .25 = 16.5 Have a great day.
Answer:
Step-by-step explanation:
∵∛x = (x)^1/3
∴
So you can replace the radicals by fractional exponents
Answer:
63 m
Step-by-step explanation:
We know the rate in 45 m / min
We need to change the time to min
1 min 24 sec
We know that 1 min = 60 sec so 24 seconds is 24/60 ths of a minute
1 min 24/60 min
1 2/5 min
Changing to decimal form
1.4 minutes
Now we multiply by the rate to get the distance
d = r *t
d = 45 m/ min * 1.4 min
d= 63 m
Formula for an is 3n - 11
Step-by-step explanation:
- Step 1: Equation for a(n) = a + (n - 1)d where a = - 8, d = common difference = a2 - a1 = -5 - -8 = 3
⇒ a(n) = -8 + (n - 1)3 = - 8 + 3n - 3 = 3n - 11
Answer:
Step-by-step explanation:
You need to analize the information provided in the exercise.
According to the data given, Dan must do homework for of an hour.
He also must clean his room for of an hour.
Then, in order to find the fraction of an hour in which Dan must do the actividies mentioned above before he can play, you need to add the fractions given.
Since they have different denominators, you need to find the Least Common Denominator. This is:
Divide each original denominator by the LCD and multiply the corresponding numerator by the quotient obtained.
Then:
