Step-by-step explanation:
How do you find average speed with distance and time?
Divide the distance by the time.
This will give you the average speed per unit of time, usually hour. So, if Ben traveled 150 miles in 3 hours, his average speed is 50 miles per hour
How do you find average speed with hours and minutes?
How to calculate average speed. Speed is distance divided by time. Simply put, if you drove 60 kilometer's for one hour, it would look like this: Speed = distance (60 km) / time (1 hour) = 60km/h.
Local(L) = 1 x (15.99)
Online(O) = (1 x 13.99) + 6
So use that equation until you find the same number.
L1=15.99
O1=19.99
L2=31.98
O2=33.98
L3=47.97
O3=47.97
And your answer will be three from local and three from online.
Answer:
27.5
Step-by-step explanation:
first you find what 30x30 is as A squared plus B squared is equal to C squared. your A is 12 and your C is 30.
so!
30x30 is 900
12x12 is 144
subtract 144 from 900 and you get 756. once you find the square root you get 27.49. then round up to 27.5

Step-by-step explanation:
Her error is in squaring (2y)²
She has (2y)² = 2y²
when it should be 2y × 2y = 4y²
Then
(2y)² = 6² + 8²
4y² = 36 + 64
4y² = 100 ( divide both sides by 4 )
y² = 25 ( take square root of both sides )
y = 
= 5
