Answer:
6.8yards/seconds
Step-by-step explanation:
Speed = Distance/Time
Given the following
Distance covered = 1232 yards
Time taken = 180 seconds
Substitute to get the speed
Speed = 1232/180
Speed = 6.84
Hence whirlwind's speed in yards per seconds to the nearest tenth is 6.8yards/seconds
The measure of the exterior angle of a regular polygon is the quotient when a whole revolution, 360 degrees, is divided by the number of sides (n). This is shown in the equation,
A = 360 / n
From the given above,
40 = 360 / n ; n = 9
Therefore, the answer is letter B. 9.
2nd questions answered is to subtract the x so C. I’m positive
9x-3y=3. |x3| 27x-9y=9
3x+8y=-17. |x9|27x+72y=-153
--------------------------------- -
-81y=162
y=-2
9x-3y=3
9x-3(-2)=3
9x+6=3
9x=3-6
x=-3/9
x=-⅓
x=-⅓
y=-2
