Answer:
62 m/s = 138.7 mi/h
Step-by-step explanation:
62 m/s = 62 x (3600/1000) x (1/1.61)
= 138.7 mi/h
Best Regards!
No, 2750 is a sadly unreasonable estimate.
917 is almost 1,000 .
33 times as much is around 30,000 .
2,750 is less than 3,000 .
Answer:
(Unusual)
Step-by-step explanation:
1/5 for one drawing
1/5 chance to win once, if there is only one game.
Then multiply them together to get 1/25.
If you need in decimal form 1/25 = 0.04 (unusual)
Answer:
(x-7)^2 + (y-2) ^2 = 130
Step-by-step explanation:
We need to find the length of the radius
the length of the radius is found by using the distance formula
r = sqrt( ( -2-7)^2+( -5 -2)^2)
sqrt( ( -9)^2+( -7)^2)
sqrt( 81+49)
sqrt(130)
The formula for a circle is
(x-h)^2 + (y-h) ^2 = r^2
where (h,k) is the center and r is the radius
(x-7)^2 + (y-2) ^2 = 130
Answer:
Step-by-step explanation:
Let the 4 greatest numbers be, A, B, C D
(A + B + C + D)/4 = 8
Total sum = 4 × 8
= 32
Let the 4 lowest numbers be, D, E F G,
(D + E + F + G)/4 = 20
Total number = 4 × 20
= 80
Hence, the difference between the sums of the 3 greatest number and the 3 smallest numbers:
A, B, C and E, F, G
= D + (E + F + G) - (A + B + C) - D
= (E + F + G) - (A + B + C)
= 80 - 32
= 48.
