2. 1.05.
Step-by-step explanation:
Their savings increase by 1.05x every year.
Fun, geometry disguised as probability.
That's a pentagon, which we can view as 10 right triangles with legs a and s/2 (half of s) and hypotenuse r. So area of the pentagon is
P = 10 × (1/2) a (s/2) = 10 (1/2) (3.2) (4.7/2) = 37.6
The area of the circle is πr² so the circle area is
C = π (4²) = 50.265482
The white area is the difference, C-P, and the probability we seek is the fraction of the circle that's white, so (C-P)/C.
p = (C-P)/C =1-P/C = 1-37.6/50.265482 = 0.251971
Answer: 0.25
Higher than I would have guessed from the figure.
Answer:
Step-by-step explanation:
2 cups=8/4 1/2=2/4 1/8=0.5/4
8/4-1/4=7/4
7/4-2/4=5/4
5/4-0.5/4=4.5/4
Answer:1 0.5/4 cups
Answer:
42
Step-by-step explanation:
because 2+2+2=6×7=42
Answer:
cos B= 7/25
tan B = 24/7
sin B = 24/25
Step-by-step explanation:
cos B= adjacent/hypotenuse = 7/25
tan B = opposite/adjacent = 24/7
sin B = opposite/hypotenuse = 24/25
