An average good clip is about 6minutes/mile for runs over 5 miles 7.2km is about 0.6km/mile x 7.2km= 4.2 miles
Answer:
324π in²
Step-by-step explanation:
The surface area of a sphere = 4πr² ( r is the radius )
Calculate r using the volume (V) formula
V = 
πr³
Here V = 972π , thus
πr³ = 972π ( divide both sides by π )
r³ = 972 ( multiply both sides by 3 to clear the fraction )
4r³ = 2916 ( divide both sides by 4 )
r³ = 729 ( take the cube root of both sides )
r = ![\sqrt[3]{729}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B729%7D)
= 9
Thus
surface area = 4π × 9² = 4π × 81 = 324π in²
Answer: average speed of the train = 4,483.0 km/h
Step-by-step explanation:
Speed = Distance / Time
Distance = 66 km
Time = 15.47 cancelling 15, we have 60 sec added to 47 sec
<u> - 14.54</u>
= 14. 107 60 + 47
<u> - 14. 54</u>
<u> 53secs</u>
53secs to hours becomes =
60 secs = 1 min
60 min= i hour
therefore 53seconds =53/3600=0.0147222hours
Speed= 66/ 0.0147222= 4,483.025
Rounding to 1 dp becomes= 4,483.0 km/h
Answer:
y= 20 m
x= 15 m
z= 22 degree
Step-by-step explanation:
15+x=30 m
x=30-15
x= 15 m
z-18=40
z= 40-18
z= 22m
Answer:
option b
6 C 2 + 6
Step-by-step explanation:
Given in the question that,
number of pink beans = 87
number of purple beans = 74
number of white beans = 35
number of black beans = 70
number of orange beans = 25
number of green beans = 47
<h3>Step 1</h3>
if two beans selected are different
6 C 2
(6 colours of beans)
<h3>Step 2</h3>
if two beans selected are same
6 C 1 = 6
(6 colours of beans)
<h3>Step 3 </h3>
total sample space will be
6 C 2 + 6
