Laketown had 215 inches of snowfall last year, but only 155 inches this year. What was the percent decrease in snowfall for Laketown to the nearest percent? A. 28% B. 39% C. 72% D. 139%I think A
Answers
Answer 1
Answer:
Okay, so FIRST you would subtract 215 - 155, which is 60, and THEN divide it by 215, so 60 divided by 215 = 0.27, and rounded that is 0.28, then you move the decimal two places to the right to make it a percentage so your answer would be A., 28%

Answer 2
Answer:
*lets do this step by step*
1st. subtract
215 - 155 = 60
2nd. divide
60 ÷ 215 = 0.2790697674
3rd. we round
0.2790697674 = 0.28
answer? A.) 0.28
hope this helps:)

The transverse axis is parallel to the y-axis (the positive part of this equation.
(h, k) is the center ... (0, 0)
a = distance from the center to the vertices along the transverse axis
b = distance from the center to the endpoints of the conjugate axis
c = distance from the center to the foci along the transverse axis
Given: a = 10
The relationship between a, b, and c is
10² + b² = c²
The slope of the asymptotes is ±5/4
a = is a multiple of 5
b = is a multiple of 4 ... be careful not to always assume that a=5 and b = 4.
For this problem a = 10
hence, b = 8
10² + 8² = c²
164 = c²
2√41 = c
Summary
center = (0, 0)
a² = 100
b² = 64
c² = 164
transverse axis x = 0
equation of the hyperbola
[y²/10²] - [x²/8²] = 1
Remember, the slope of the asymptotes tell you the ratio of a and b, and not necessarily the actual values of a and b.

2m 60cm is think because half off 100 is 50 so add 10 on and you get 60
