Answer:
85/100 = x/20
100x = 1700
x = 17 questions she answered correctly
x + 17 = 20
x = 3 questions she answered incorrectly

Answer:
x = 3, y = 1
Step-by-step explanation:
2 raised to what power gives you 16?
2*2*2*2 = 16 so 2^4
3 raised to what power gives you 9?
3*3 = 9 so 3^2
the exponent cannot be negative so x has to be greater than y and x cannot be the same as y otherwise you will get a 0.
x = 3 , y = 1
2^(3+1) = 2^4 = 16
3^(3-1) = 3^2 = 9
Answer:
6.63 cm
Step-by-step explanation:
The segments within the circle form a right angle. Triangle CRS as a right triangle must follow the Pythagorean theorem which says the square of each leg adds to the square of the hypotenuse.
a² + b² = c²
Here a is unknown, b = 10 and c = 12.
a² + 10² = 12²
a² + 100 = 144
a² = 44
a = √44 = 6.63
