Answer:
40 square inches
step-by-step explanation:
The new club sticker is in the shape of a triangle
It has a height of 8 inches
And a base of 10 inches
Area of a triangle is given by: 
× base × height
Area of the triangular club sticker = × 10 inches × 8 inches = 40 square inches.
-4:9 - This is half of the local gravitational constant, -9.8 m/s^2.
29:4 - The initial velocity of the arrow as it was shot upward was 29.4 m/s <u>(approximately 66 mph)</u>
Answer:
Speed = 8mph
Step-by-step explanation:
Speed of wind = 4mph
Let speed of Darrin with no wind be "x" mph
then resultant speed of Darrin, travelling in direction of wind = (x + 4) mph
Using a result, Time = Distance travelled / Net speed
Time taken by Darrin to travel 6miles in direction of wind = 6 / (x + 4)
When Darrin travel in opposite direction of wind, then its net speed = (x - 4)mph
Darrin travel 2 miles against the wind in 6/(x + 4) hr
then Distance = speed × time
2 = ( x- 4 ) × ( 6/x + 4)
2x + 8 = 6x - 24
4x = 32
x = 8 mph
Therefore speed of Darrin skateboard with no wind = 8mph
