Answer:
40%
Step-by-step explanation:
You do 10/25 and to make that a fraction you have to make the denominator 100 so we multiply the numerator and denominator by 4. Which gets us 40/100 or 40%.

Answer:
The value of
.
Step-by-step explanation:
Diagram of the given scenario shown below.
Given that,
Distance from bench to Jasmyn is
.
Distance from bench to Willard is
.
From the Question,
The given wishing well is a circle and all the distance are tangent to the circle.
So, Triangle formed by these points are such as Δ
and Δ
.
Now, taking both Δ
and Δ
.
⇒
{Radius of circle are equal}
⇒
{Common side}
⇒ ∠
∠
{radius is always perpendicular
to the point of tangent }
∴ Δ
≅ Δ
{By SAS congruence theorem}
Therefore,
....(1) {corresponding part of
congruence triangle (CPCT)}
Thus,
⇒
{from equation (1)}
⇒
⇒ 
Hence, The value of
.
Answer:
2/π ≈ 0.637 m/s
Step-by-step explanation:
The rate of change of area with respect to time is ...
A = πr²
dA/dt = 2πr·dr/dt
Filling in given values in the above equations, we can find r and dr/dt.
25π = πr² ⇒ r = 5
20 = 2π·5·dr/dt
dr/dt = 20/(10π) = 2/π . . . . meters per second
The radius is increasing at the rate of 2/π ≈ 0.637 meters per second.
