Answer:
50.2 m^2
Step-by-step explanation:
The Area of a circle is given by the equation pi(r)^2
Therefore if r = 4 we can plug it into the equation to get:
pi (4)^2= pi(16)= 50.2655 or about 50.2 m^2how can you represent rational numbers on a number line, as decimals, and in real-world situations?

-15/-18=10/x
what is X?
Answer:
12
Step-by-step explanation:
(-15)/(-18) = 10/x cross multiply expressions
-15x = -180 since both sides are negative we can write without the sign
15x = 180 divide both sides by 15
x = 12

Help me PLEASEEEEE I will give brainlyest if the answer is correct
Answer:
See Below
Step-by-step explanation:
Lets look at our numbers:
The balloon is at 1000 feet.
The balloon drops at a constant speed of -4 1/2 per second.
How long will it take to get to 215ft, in seconds, s.
Lets see, if you were to subtract 1000-215, you will get 785.
The balloon needs to drop 785ft to get to 215ft above the ground.
The question asks how long will it take to get below 215ft.
Lets do the math for the descending feet. We calculated that it takes 785ft to hit 215ft above the ground, so, you need to divide 785ft by 4 1/2 to see how many seconds it takes. The answer for this is 174.4, we can make this 174 4/9.
**VERY IMPORTANT** If you use 174 4/9, this equals 215 seconds, it asks for below this, so you can use ANY number for this that it above this number.
Now for the inequality, look at the question, it asks how long will it take to get below, not equal to or more below, meaning that you can cancel out the inequality signs with lines below them. So your answer is 270 > ,
Please tell me if this is right, if its not let me know I apologize.

The table shows the attendance at the art show for the past week.
What does the attendance need to be on Saturday to have an average attendance for the week of 30 people per day?
Answer: The correct answer is - 50.
Step-by-step explanation: :)
Answer:
50
Step-by-step explanation:
To calculate the mean, we do the total divided by the number of values. Therefore, to get 30, with 7 values, we need to have a total of 210. Currently, we have a total of 160, so Saturday needs to be 50, because 210-160=50.
