Step-by-step explanation:
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.
Hey there!
To find the range, first put the numbers in order from smallest to largest.
97, 163, 169, 175, 184, 199
Then take the largest number, 199, and subtract the smallest number (in this case, the outlier) which is 97.
199-97=102

Answer:
Step-by-step explanation:
Sin(30o) = 0.5 or 1/2
Sin(60o) = sqrt(3)/2
So the statement is false
Let the length of the shortest side = x
The two longer sides that are equal = 3x
The are two equal longer sides, so their total is 3x + 3x = 6x
3x+ 3x + x= 35 Collect like terms on the left
7x = 35 Divide by 7 on both sides
x = 35/7
x = 5
Answer
Two long sides -- 15 cm each
Shortest side -- 5 cm
