Answer:
∠ D = 127°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ D is an exterior angle of the triangle , then
∠ D = 85° + 42° = 127°
1 m = 100 cm
1 book = 2cm wide.
Number of books = 100 ÷ 2 = 50 books.
Answer: 50 books can fit on the shelf.
Answer:
c = 2.25
Step-by-step explanation:
f(x) is a continuous and differentiable function on the interval, so the Mean Value Theorem guarantees a value for c exists.
The average slope is ...
m = (f(4) -f(1))/(4 -1) = (24 -12)/3 = 4
The point at which the derivative is 4 is ...
f'(c) = 6/√c = 4
√c = 6/4
c = 2.25
Answer:
30
Step-by-step explanation:
8 plus 12 is 20
20 divided my 4 is 5
5 plus 5 is 10
6 minus 3 is 3
10(from the first half) times 3(from the second half) is 30
