Answer:
Malcolm’s maximum speed is 200 km/h and and Ravi’s maximum speeds is 320 km/h.
Step-by-step explanation:
Let x and y are the maximum speeds ( in km / h ) of Malcolm and Ravi respectively,
Then according to the question,


Again according to the question,


Equation (1) + equation (2),
3x = 600
⇒ x =
= 200,
From equation (1),
200 + y = 520
⇒ y = 520 - 200 = 320
Hence, Malcolm’s and Ravi’s maximum speeds are 200 km/h and 320 km/h respectively.
Answer:
An acute angle is an angle less than 90°
The options are H,H,T or T,T,H
HHT: 1/2 x 1/2 x 1/2 = 1/8
TTH: 1/2 x 1/2 x 1/2 = 1/8
HHT or TTH: 1/8 + 1/8 = 2/8 = 1/4
Answer: 1 out of 4 = 1/4 = 25%
Answer: x = -2 and 4
Step-by-step explanation:
x^2 - 2x - 8 = 0
(x - 4)(x + 2) = 0
