Answer:
the leaf is 8 meters away from the tree
Step-by-step explanation:
we can think of this problem as a right triangle where height represents a leg, and what flew the bird represents the hypotenuse
then we would have to find the other leg
for this we can use Pythagoras
h = hypotenuse = 17 meters
l1 = leg1 = 15 meters
l2 = leg2 = ?
h² = l1² + l2²
17² = 15² + l2²
17² - 15² = l2²
289 - 225 = l2²
64 = l2²
√64 = l2
8 = l2
the leaf is 8 meters away from the tree
Answer:
0.7
Step-by-step explanation:
this is the answer because the zero means less in this equation.
Answer:D
Step-by-step explanation:
(3x^3 - 5x^2 + 4x - 9)-(7x^3 - 8x^2 - 5x + 10)
open brackets
3x^3 - 5x^2 + 4x - 9 - 7x^3 + 8x^2 +5x - 10
Collect like terms
3x^3-7x^3-5x^2+8x^2+4x+5x-9-10
-4x^3+3x^2+9x-19
It will take the cheetah 4 seconds to run 80 yards.
Step-by-step explanation:
Given,
Distance covered by Cheetah in 5/2 seconds = 50 yards
Ratio of distance to time =
Let,
x be the time required to cover 80 yards.
Ratio of distance to time = 80 : x
Using proportion;
Ratio of distance to time :: Ratio of distance to time
Product of extreme = Product of mean
Dividing both sides by 50
It will take the cheetah 4 seconds to run 80 yards.
