Answer:
100
Step-by-step explanation:
because 5+5=10
the 10^2=10*10=100
1.87 is 8.5% of 22 so 8.5% of 80 is 0.085 x 80 so $6.80
A) 51, assuming this is a *right* triangle:
38^2+34^2 = 50.99^2, rounding 51!!
Answer:
Yes, No, No, No
Step-by-step explanation:
To decide whether the point lies on the circle, what you need to do it simply substituting the x and y values into the equation and check if it add up to be 25
(-5)² + 0² = 25, = RHS [Yes]
1² + (√7)² = 8, ≠ RHS [No]
(√21)² + (-3)² = 30, ≠RHS [No]
0² + 7² = 49, ≠RHS [No]
