Answer:
38cm taller
Step-by-step explanation:
jack is 178cm tall
the ladder is 280cm tall
jack standing on the ladder is 280cm taller
so 178+280=458
the tree is 420cm tall
458>420
which means that jack is now taller than the tree standing in the ladder
458-420=38
so jack is 38cm taller than the tree standing on the top of the ladder
Answer:
Its D
Step-by-step explanation:
Given y = 7/x² + 10
Let,
y = f(x)
f(x) = 7/x² + 10
And,
g(x) = x²
Hence, f(g(x))
Reason is;
You have to rewrite f(x) so that it can fit in g(x) into the equation
f(x) = 7/g(x) + 10
We have to deal with the distance in more detail
If the turtle is 11 times faster than the snail, the amount of distance he will cover is 11 times more.
d/(360 - d) = 1/11
11d = 360 - d
12d = 360
d = 30 The Snail covers 30 meters. The turtle covers 11*30 = 330 meters.
Answers
Rate of snail = 30 meters / 40 minutes = 3/4 meter / minute
Rate of turtle = 330 meters / 40 minutes = 8.25 meters / minute.
