The answer is B. 4 3⁄8 yards. The amount of material needed for the jacket is: x = 2 5/8 yd = 2 + 5/8 = 16/8 + 5/8 = (16+5)/8 = 21/8 yd. The amount of material needed for the skirt is: y = 1 3/4 yd = 1 + 3/4 = 4/4 + 3/4 = (4+3)/4 = 7/4 yd. The total amount of material Jane needs is: x + y = 21/8 + 7/4 = 21/8 + 14/8 = (21+14)/8 = 35/8 = (32+3)/8 = 32/8 + 3/8 = 4 + 3/8 = 4 3/8 yd.
It takes 10 workers 5 days to complete a road repair when working 2 hours a day.
So, this becomes :
man hours required to finish the work.
Given is, if 2 people work for 5 hours a day, then let the number of days to finish the road be = d
So, total man hours = ![2*5*d=10d](https://tex.z-dn.net/?f=2%2A5%2Ad%3D10d)
Now,
or ![d=10](https://tex.z-dn.net/?f=d%3D10)
Hence, it will take 10 days for 2 people working 5 hours daily, to complete the work.
Answer:
Question 3: D, 90°
Question 2: D, 84°
Step-by-step explanation:
In this question , we have to find the region that is represented by the intersection of sets A and B .
Intersection refers to the common area , that is , the area shared by A and B .
And in the given diagram, the only region shared by A and B is region II.
So Intersection is represented by region II and the correct option is the first option .
