Reciprocal of =
For finding reciprocals of fractions, simply flip the numerators and denominators.
Answer:
Step-by-step explanation:
if we need to approximate,
the radius=125, the diameter is d=250
we estimate that pi=3
C=3*250=aprox 750
the closest number is 785
The angle you want - call it <em>θ</em> - is such that
tan(<em>θ</em>) = FC / AC
Find the length of the diagonal AC, i.e. a diagonal of the rectangle ABCD. ABC forms a right triangle with legs AB = 70 and BC = 50, so
AC² = AB² + BC²
→ AC = √(70² + 50²) = 10 √74
Find FC using the given angle of the sloping face:
tan(30º) = FC / BC
→ 1/√3 = FC / 50
→ FC = 50/√3
Now solve for <em>θ</em> :
tan(<em>θ</em>) = (50/√3) / (10 √74)
→ tan(<em>θ</em>) = 5/√222
→ <em>θ</em> ≈ 18.6º
Answer: a. Ratio b. Nominal c. Interval d. Ordinal
Step-by-step explanation:
1)Ratio:You can do all sort of arithmetic on the cholesterol level.
2)Nominal: These cannot be ordered or arithmetic cannot be applied
3)Interval: It is interval because it is a number and midnight means 0 so you cannot use it for division
4)Ordinal: You can arrange it in increasing or decreasing order.
Bike to work: d=16*t
ride home: d = 27*.4 =10.8
solve for t
10.8 = 16*t
t = 10.8/16
0.7 of an hour
