Can u post a clearer pic? i can help u if u do :)
Multiply 1 by 125, and 25 by x so you can solve for x.
So, the rate per 7 minutes is 7:196
To find the unit rate (how many spins per minute) we need to divide the 196 by 7.
196/7 = 28
The unit rate is 1:28
At this rate, the unicycle makes 420 revolutions per 15 minutes. We find this by 28 * 15 = 420.
Answer:
h = 1.41
c = 3.46
Step-by-step explanation:
See the triangles diagram attached.
For the first triangle, Base = h, Hypotenuse = 2 and the angle between base and hypotenuse is 45°.
Therefore,
⇒
(Answer)
{Rounded to the nearest tenth}
Again in the second triangle, Perpendicular = c, Hypotenuse = 4 and the angle between base and hypotenuse is 60°.
Therefore,
⇒
(Answer)
{Rounded to the nearest tenth}
