Answer:
We can find the radius from circumference and then area
Circumference(C) = 2πr
r = C/2π
r = 20/2π
r = 10/π
Area = πr²
Area = π × 10/π × 10/π
Area = 100/π
Area = 100/3.14
Area = 10000/314 = 31.84 cm² (approx)
Area = 32 cm² (Rounding to nearest whole number)
Answer:
The answer is 3
Step-by-step explanation:
First write the equation as you see it.
-11b+7=40
Then switch the take away seven from the left side then place it in the right side but as a minus.
-11b=40-7
Next do the math on the right side.
-11b=33
Once you have done that you divide the number on right with the number on the left which leaves you with the answer.
b=-3

It would take 4.44 minutes to fill the sink using both faucets P and faucet Q together
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let t represent the time it takes to fill the sink using both faucets together, hence:
(1/10 + 1/8)t = 1
t = 4.44 minutes
It would take 4.44 minutes to fill the sink using both faucets P and faucet Q together

it is 6!/8!
because you take the first and second place you take it as a whole team, and divided by all the cases
Answer:
Q1. The estimated sum of the two people are between 40 and 55 years old.
Q2. The first person is between 10 and 15 years older.
Step-by-step explanation:
We are given Age Range's for 2 people. The first question is asking for the sum of the two people's ages. In this case we can just <u><em>add</em></u> the two minimum ages together and then the two maximum ages like so,
<u>min:</u> 25 + 15 = 40
<u>max:</u> 35 + 20 = 55
So the estimated sum of the two people are between 40 and 55 years old.
The second question asks how much older the First person is from the Second person. We can calculate this by <u><em>subtracting</em></u> both age ranges like so,
<u>min:</u> 25 - 15 = 10
<u>max:</u> 35 - 20 = 15
So the first person is between 10 and 15 years older.
