Answer:
2 : 1
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
AC : DF = 8 : 4 = 2 : 1
The correct answer is A: 2.
The slope compares the vertical change (the rise) to the horizontal change (the run) when moving from one fixed point to another along the line.
If you look at your graph, it takes 2 units up and 1 unit to the right in order to get to the next point on the line.
Therefore, the slope of the line is 2/1, or simply 2. It has a positive value because the line is sloping upward.
Answer:
0+5+20= 25 the answer is 25
Answer:
That is 74 years.
Step-by-step explanation:
1.5% = 0.015.
The equation for the rate of growth is P = 430,000(1.015)^n where n is the number of years.
Triple the population is 430,000 * 3 = 1,290,000, so:
1,290,000 = 430,000(1.015)^n
(1.015)^n = 1290,000 / 430,000 = 3
Taking logs of both sides:
n log 1.015 = log 3
n = log 3 / log 1.015 = 73.8 years
Answer:
46°
Step-by-step explanation:
tan Ф = 21/20
Ф = tan-1 (21/20)
= 46°
