Answer:
Therefore 510 number of Sweaters can be made in 1734 meters cloth.
Step-by-step explanation:
Given:
A clothing designer had 1,734 meters of fabric to make Identical sweaters
i.e Total Cloth available = 1734 meters
Cloth use for One Sweater = 3.4 meters
To Find:
Number of Sweaters = ?
Solution:
By Unitary Method we have
For 3.4 meter cloth,
Number of Sweater = 1
Therefore for 1734 meter cloth,
Number of Sweater = ?
Therefore 510 number of Sweaters can be made in 1734 meters cloth.
The first one because it’s the actual formula for a sphere and it has pie at the end because we are solving for a sphere
Answer:
1.22 km/min
Step-by-step explanation:
Let Q be baloon height at a time t. Our goal is to determine the speed of the baloon at the moment.
The dy / dt velocity of the baloon when = π/5?
So we can restate the question as follows:
Owing to the fact d / dt = 0.2 rad / min at some stage = π/5
from fig:
tanθ = y/4
Differentiating w.r.t "t"
sec2 θ * dθ/dt = 1/4(dy/dt)
=> dy/dt = (4/cos2 θ)dθ/dt
At the given moment θ = and dθ/dt = 0.2 rad/min.
dy/dt = (4/cos2)* (0.2)
= 1.22 km/min
And the velocity of the baloon currently is 1.22 km / min.
