B. She has gotten 35 points because 7*5=35
Answer:
B
Step-by-step explanation:
The circumference of a circle is denoted by: C = , where d is the diameter.
Here, the diameter is d = 50. So, plug this in: C = ≈ 157
Thus, the answer is B.
Hope this helps!
The required time is mathematically given as
t-150 minutes.
This is further explained below.
<h3>What is the time?</h3>
We know that the volume of the prism is given by.
Volume
Base Area
Base Area
Now,
Given that there is a twenty percent drop in the level of the pond during the first thirty minutes.
Because of this, the volume increases.
Now, the rate of emptying the tank is,
In conclusion, We also know that,
$$
Therefore, Colin must wait for the pond to drain for a total of 150 minutes.

Answer:Let's solve your equation step-by-step.
24=x2−4x+3
Step 1: Subtract x^2-4x+3 from both sides.
24−(x2−4x+3)=x2−4x+3−(x2−4x+3)
−x2+4x+21=0
Step 2: Factor left side of equation.
(−x−3)(x−7)=0
Step 3: Set factors equal to 0.
−x−3=0 or x−7=0
x=−3 or x=7
Answer:
x=−3 or x=7
