Answer:
t = 100 minutes, or 1 hr, 40 minutes
Step-by-step explanation:
5/15 of 1 hour is the same as 5/15 of 60 minutes, which is 20 minutes
you can set up a proportion of hw completed / minutes = hw completed / min:
(1/5 ÷ 20) = (1 ÷ t) we use '1' to indicate all homework (or 100% of hw) and 't' to indicate time required
cross-multiply to get:
20 = 5/t
t = 100 minutes, or 1 hr, 40 minutes
(-3/2,11/2) is the midpoint
Your answer is 9-1/2x+5+4•x
Answer:
Rational
Step-by-step explanation:
<u>Rational numbers:</u>
Rational numbers are such numbers that can be expressed in the form p/q, where the value of q must not be equivalent to 0.
<u>Irrational numbers:</u>
These numbers cannot be expressed in the form p/q, where the value of q must not be equivalent to 0. <u> </u>
![\implies 2.89 = \dfrac{289}{100} \ \ \text{[In} \ \frac{\text{p}}{\text{q}} \ \text{form (\text{q}} \neq 0)]}](https://tex.z-dn.net/?f=%5Cimplies%202.89%20%3D%20%5Cdfrac%7B289%7D%7B100%7D%20%5C%20%5C%20%5Ctext%7B%5BIn%7D%20%5C%20%20%5Cfrac%7B%5Ctext%7Bp%7D%7D%7B%5Ctext%7Bq%7D%7D%20%5C%20%5Ctext%7Bform%20%28%5Ctext%7Bq%7D%7D%20%5Cneq%200%29%5D%7D)
Thus, 2.89 is a rational number.
