Try finding the area or perimeter of the triangle then
Answer:...
Step-by-step explanation:
So first take triple 3 which would be 3+3+3 or 3x3.
Then take double 8 which would be 8+8 or 8x2.
So all you need to do is write it in the associative property.
So it would look like this:
(3x3)+(8x2)= 25
9 + 16
Because 3x3 is 9 and 8x2 is 16 so you just need to add them to get the product.
Answer:
V = 5 m/h
Step-by-step explanation:
An aircraft carrier, traveled 9 hours at speed of 25 mph, that means the aircraft position from Hawaii (the start point of the journey) is:
25 m/h * 9 h = 225 miles far away from hawaii
When the aircraft has traveled 9 hours, the submarine has traveled 11 hours ( since its departure was 2 hours earlier ). They both traveled in opposite directions.
Then distance between the two vessels = d
d = 280 miles
280 = 225 miles (from the aircraft to hawaii ) + traveled distance for the submarine
And
Traveled distance by submarine d(s) = V* 11 miles/hour. where V is speed of submarine
Then
280 = 225 + 11*V ⇒ 11*V = 280-225 ⇒ 11*V = 55/11 mph
V = 5 m/h
