X would be 4! Since there is a right angle the two sides making the right angle are even!
Answer: 50.24 square centimeters.
Step-by-step explanation:
Given: The radius of the circular lens of a magnifying glass = 4 centimeters
The area of a circle is given by :-
, where r is the radius of the circle.
Then the area of the circular lens of a magnifying glass is given by :-

Hence, the area of the circular lens of a magnifying glass = 50.24 square centimeters.
Answer: 25^8
Step-by-step explanation: just write it out the number of times the outer exponent says so
5^4 x 5^4= 5x5= 25 and since you add the exponents 4 plus 4 is 8
18.44 because Pythagorean Theorem says that 12^2 + b^2 = 22^2. Then to solve you square the numbers, 144 - b^2 = 484, then subtract 144 from 484 and get 340, and the square root of 340 is 18.44.
Answer:
40 shows
Step-by-step explanation:
Seth’s father has spent $140.
At the regular price, the number (n) of shows Seth could attend is
n = 140/3.50
n = 40
If Seth attends 40 shows at that price, he will have spent $140.
Every show after that will cost only $1 instead of $3.50.
Seth must attend 40 shows for it to benefit his father.
