Hello! I can help you with this! So, Mami Kudo ran 255.303 kilometers in 24 hours. I’m guessing that we have to find the answer in kilometers per hour. 255.303/24 is 10.6376 and other numbers or 10.64 when rounded to the nearest hundredth. Mami Kudo’s average speed was about 10.64 kilometers per hour.
Answer:
x=-4
Step-by-step explanation:
First, distribute the 4
this makes 4x + 36 = 20
Then, subtract 36 to combine like terms. 4x = -16
divide 4x! x = -4
Pythagorean theorem: a^2 + b^2 = c^2
a^2 + 16^2 = 65^2
a^2 + 256 = 4225
a^2 = 3969
a = 63
Perimeter: add all sides
63 + 16 + 65 = 144
Solution: 144 feet
Answer:
A. 1
Step-by-step explanation: You have to substitute the numbers in for x
A. 1:
-5x -1 < -9
-5(1) - 1 < -9
-5 - 1 < -9
-6 < -9
B. 2:
-5x - 1 < -9
-5(2) - 1 < -9
-10 - 1 < -9
-11 < -9
C. 3:
-5x - 1 < -9
-5(3) - 1 < - 9
-15 - 1 < -9
-16 < -9
D. 4:
-5x - 1 < -9
-5(4) - 1 < -9
-20 - 1 < -9
-21 < -9
- Remember, a negative plus another negative is a negative
Hope this helps you!!! :)
Given that the tornado traveled 260 miles in 4 hours, its initial speed is 65 mi/h. Then, slowing by 20% every hour, the speed after 2 hours can be calculated through the equation,
speed = (65 mi/h) x (1-0.2)^2
speed = 41.6 mi/h
Thus, the speed of the tornado after 2 hours is approximately 41.6 mi/h.
