Given:
CH = 3960 miles
Altitude = 240 miles
To find:
The distance from the space station to the horizon.
Solution:
The reference image for answer is attached below.
Radius = 3960 miles
CD = CH = 3960
ED = 240
EC = CD + ED
= 3960 + 240
EC = 4200 miles
By Pythagorean theorem:



Subtract 15681600 from both sides.


Taking square root on both sides, we get


The distance from space station to the horizon is approximately 1400 miles.
Answer:
20/7 dollars per hour
Step-by-step explanation:
He pays 10 dollars per 3 1/2 hours. To find the unit rate, we divide the two.
10 / (3 1/2) =
10 / (7/2) =
(10/1) x (2/7) =
20/7
1/2 / 4
which can be rewritten as 1/2 * 1/4 (i bet you learnt how to divide fractions ... if you didnt then comment and ill tell you the rules for dividing)
1/2 * 1/4 = 1/8
Answer:
11 ft
Step-by-step explanation:
The ring takes circular shape and for a circle, circumference is given by

Where C represent circumference and d is the diameter.
Taking use 3.14 for pi as instructed and substituting 3.5 ft for diameter d then
C=3.14*3.5=10.99 ft
Rounding off, this is approximately 11 ft
38 mm to m
38 mm * (0.001 m / 1 mm)
**cancel mm units**
38 * (0.001 m / 1)
0.038 m
you're correct
