Answer:
A
Step-by-step explanation:
Speed = distance/ time
=10km/ 1hr(60mins)
= 10km/ 1hr
=10km/hr
Answer is B. 2.19/Ib (just divide 4 by 8.76)
Answer:
The height of building to the nearest foot is h = 36 foot
Step-by-step explanation:
We have given,
Length of ladder leaning against a building, l = 45 foot
Bottom length between ladder and the building , b = 27
Now, we need to find the height of building to the nearest foot.
Let the height of building be h.
Using Pythagoras theorem,

Here, l = 45 , b = 27 and h =?
So,

h² = 45² - 27²
h = √(45² - 27²)
h = 36
The height of building to the nearest foot is h = 36 foot
Step-by-step explanation:
Fraction = 280% / 100%
= 280/100 = 14/5 or 2 4/5.
The interior angles next to the 2h angles are congruent and each one measures 70 degrees. Since the interior angle is 70 degrees the exterior angle is 110 degrees.
2h = 110
divide both sides by 2
h = 55
