Answer:
Six numbers have perfect square factors
Step-by-step explanation:
The numbers with perfect square factors are those numbers that have perfect squares as one of the numbers that can divide them.
They include:
4 = 2 * 2
16 = 4 * 4
36 = 6 * 6
49 = 7 * 7
64 = 8 * 8
81 = 9* 9
These numbers above have perfect square factors because they are formed from integers that multiply themselves.
A 16 1/2 pound rock is 6 more pounds heavier than a 10 1/2 pound rock.
Answer:
-10
Step-by-step explanation:
First use this equation: (y2 - y1) / (x2 -x1)
The y intercept is 14 so the slope is -10.
51,
Find angle y first by setting it equal to 180
With its adjacent angles. Then solve for x by triangle angles
16: B; irrational number, real
17: C; whole, integer, rational, real
18: B; real, rational, integer
