Add the fractions and simplify the answer 1/2 +2 /3

IrinaVladis [17]

What we are going to do is add $\frac{1}{2}$ by $\frac{2}{3}$ . The first thing we do is make common denominators for $\frac{1}{2}$ and $\frac{2}{3}$ : $\frac{1*3}{2*3}= \frac{3}{6} \ and \ \frac{2*2}{3*2}= \frac{4}{6}$ . Now we add $\frac{3}{6}$ by $\frac{4}{6}$ : $\frac{3}{6}+ \frac{4}{6}= \frac{7}{6}$ . Now we make $\frac{7}{6}$ a mixed number: $\frac{7}{6}=1 \frac{1}{6}$ . Therefore, your answer is $\boxed{\boxed{1 \frac{1}{6}}}$ . Hoped I helped. :)

If y=27 when x= 8 find y when x =11

Rina8888 [55]

Answer:

37 1/8

Step-by-step explanation:

The problem probably assumes direct variation

y=kx

IF so, then plug in the values and solve for k

27=k(8)

k = 27/8

y= (27/8)x. Now let x = 11

y = (27/8)11 = 27(11)/8 = 37.125 = 37 1/8

y = 37 1/8

the problem is making some assumption about the relation between x and y. The simplest assumption that's likely is direct variation, that x and y are linearly related. The graph is a straight line through the origin with slope = 27/8

The distance s that an object falls is directly proportional to the square of the time t of the fall. If an object falls 16 feet

Lemur [1.5K]

Answer: if S is the distance, the fact that the distance is proportional to the square of the time means that S(t) = a* $t^{2}$ where a is a constant of proportionality, with units of $\frac{feet}{s^{2} }$ .
