Answer:
Yes, the scale factor is 0.6 repeating, or 0.7.
Step-by-step explanation:
You find the scale factor by dividing the smaller sides by the corresponding larger ones.
12/18 = 0.6 repeating
14/21 = 0.6 repeating
16/24 = 0.6 repeating
These triangles could be similar by SSS or SAS or ASA I think since congruent angles are shown in both triangles as well.
Answer:
lets say they share the cost in 5 parts, because Anna will distribute 4 time as much as Emily.
120 / 5 = 24
Emily: $24 (1/5 of 120)
Anna: $24 * 4 = $96 (4/5 of 120)
In 1975 it was 1000tons, ok, well, in 1976 it went up by 10%, how much is a 10% increase?
well, in 1976 it was 1100 tons then, and in 1977 it went down by 5% of 1100, well, if we take 1100 to be the 100%, then what is a 5% decrease?
A= -2
B= 4
C= -3
The equation the help you with this for later reference is **ax^2 + bx + c=0**
From the given problem the same size is n = 70. Df = n – 1 =
70 – 1 = 69.
The population mean is u = 30, sample standard deviation is
s = 10 and the sample size is n = 70. Then,
t = x – u / s sqrt of n
1.995 = x – 30 / (10 sqrt of 70)
1.995 = x – 30 / 1.1952
X – 30 = 1.995 (1.1952)
X – 30 = 2.3844
X = 30 + 2.3844
X = 32.3844
The sample mean is 32.3844
