6.1 seconds.
In the equation L=0.8T², we will substitute 30 for L:
30 = 0.8T²
Divide both sides by 0.8:
30/0.8 = 0.8T²/0.8
37.5 = T²
Take the square root of both sides:
√37.5 = √T²
6.1 = T
Answer:
Yes, it makes it true
Step-by-step explanation:
Plug in 3 and 10 as x and y into the inequality:
y > 2x + 2
10 > 2(3) + 2
10 > 6 + 2
10 > 8
Since 10 is bigger than 8, this inequality is true.
So, (3, 10) makes the inequality true.
a The center of the hexagon and of the circle are the same point. Also length of one side of the hexagon = 90/6 = 15 units.
If we join each vertex of the hexagon to the center then we get 6 equilateral triangles (because internal angle of reg hexagon = 120 and vertex angles of the triangles = 60) so the radius = length of side of hexagon = 15 units (answer)
b Area = pi * 15^2 = 706.9 units^2 to nearest tenth. Answer
Answer:
$799.92
Step-by-step explanation:
To find his pay, multiply the number of hours he worked by his pay per hour:
22.22(36)
= 799.92
So, his pay was $799.92
