A) the perimeter of a triangle is the bottom plus the left slanty side plus the right slanty side, but you need the bottom in ft so that would be 6 ft. the perimeter is 13 ft

b) 1 yard

In a tutoring session, 2/3 of an hour was spent reviewing math problems. Adelina attended 3/4 of the tutoring session. How much

fgiga [73]

Answer:

Time spend by Adelina at the tutoring session is 30 minutes.

Step-by-step explanation:

Given : In a tutoring session, $\frac{2}{3}$ of an hour was spent reviewing math problems and Adelina attended $\frac{3}{4}$ of the tutoring session.

We have to find the time Adelina spend at the tutoring session.

We know, 1 hour = 60 minutes.

Total time taken in tutoring session = $\frac{2}{3}\times 60=40$ minutes.

also, Adelina attended $\frac{3}{4}$ of the tutoring session that is $\frac{3}{4}$ of 40 minutes.

that is $\frac{3}{4}\times 40=30$ minutes.

Thus, time spend by Adelina at the tutoring session is 30 minutes.
