It is answer D does that help?
Answer:
6/1 square feet per hour. Jeff can paint faster.
Step-by-step explanation:
So, to get Jeff's square feet to 60 minutes, you do 30x2= 60. So, you do that to 28. 28x2= 56. 56/1 is greater then 50/1. So 56-50= 6. Jeff can paint 6 square feet per hour, greater than Angela.

Answer: 170
Step-by-step explanation:
Hemisphere volume formula
V = (2/3)πr3
(2/3)•(3.14)•(2.5)^3=32.7 (33)
Cylinder volume formula
V=πr^2h
(3.14)(2.5)^2(7)=137.4 (137)
137+33=170
Step-by-step explanation:
option B is the correct answer of this question .
Answer: 78 degrees
Step-by-step explanation:
Since the angles of a triangle have to add up to 180 degrees, and angle A is 28 degrees, and angle B is 74 degrees, angle C would have to be 78 degrees so there are a total of 180 degrees in the triangle. Since triangle ABC is similar to triangle DEF, the angle measurements of that triangle would also have to be 28 degrees, 74 degrees, and 78 degrees, corresponding to angles D, E, and F. Since the largest of these numbers is 78 degrees, and angle F is the largest angle of the triangle, that would be your answer.
