The linear speed based on the information is 1326 km/h.
<h3>How to calculate the speed?</h3>
The radius will be:
= 6378 + 252
= 6630 km
The angular speed is 0.2. The linear speed will be:
= 6630 × 0.2
= 1326 km/h.

Answer:
x = 60 degree
Step-by-step explanation:
90 + 90 + 2x - 10 + 2x + 2x + 10 = 540 degree (sum of 5 interior angles)
180 + 6x = 540
6x = 540 - 180
x = 360/6
x = 60 degree
Answer:
4
Step-by-step explanation:
Think of it this way. You have 2 sets of 2.
I I (This represents two)
I I (This represents the other two)
When you combine these, you get:

Answer:
9 cups
Step-by-step explanation:
4 cups are in a quart
Andrea put 2 quarts of water in
4 + 4 is 8
She also added 1 cup of lemon juice.
8 + 1 is 9
So, 9 is your answer.
Hi there!
Solve by setting the two equations equal to each other:
-2x² + 4x + 8 = -4x + 16
Move all terms to one side:
-2x² + 4x + 4x + 8 - 16 = 0
Simplify:
-2x² + 8x - 8 = 0
Factor out a negative 2 from each term:
-2(x² - 4x + 4) = 0
Factor:
-2(x - 2)² = 0
Set the factor equal to 0 to solve:
(x - 2)² = 0
x - 2 = 0
x = 2
Substitute this value of x into an equation to find the shared y value:
y = -4(2) + 16 = 8
