The northern hemisphere is experiencing winter because the earth's axis is tilted so that the northern hemisphere doesn't receive direct sunlight. The changing of the seasons is determined by whether a place is experiencing direct sunlight or indirect sunlight due to the earth's tilt.
Answer:
99 and 100.
Step-by-step explanation:
Let's say the lower number is x. This means that the bigger number would be x+1
x+x+1=199
Simplify
2x+1=199
Subtract 1 on each side of the equation to isolate 2x:
2x=198
Divide
x=99
Let's put this to the test! The lower number(x) is 99, and the bigger number(x+1) would be 100. The total is 199.
Happy learning!

A) 3.3 m/s
1 km/ 5 minutes
=1000 m/ 5(60) s
= 1000 m/ 300s
=10/3 s
=3.3 m/s
Answer:
x = 10√3
Step-by-step explanation:
Because of the right angles, we can use Pythagoras
30² - x² = y² (a) Largest triangle
y² - 20² = h² (b) Medium triangle
substitute y² from (a) into (b)
30² - x² - 20² = h²
500 - x² = h² (d)
x² - h² = (30 - 20)² (c) smallest triangle
substitute h² from (d) into (c)
x² - (500 - x²) = 100
2x² = 600
x² = 300
x = 10√3
