50 different 5-digit numbers because it would be 5x10 which equals 50.
Answer:
7.99 m
Step-by-step explanation:
The formula for the circumference (C) of a circle in terms of its radius (r) is ...
C = 2πr
Putting in the given values, we can find r.
50.2 = 2·3.14·r
50.2/6.28 = r ≈ 7.99 . . . . . divide by the coefficient of r; round to 3 significant figures.
To 3 significant figures, the radius is 7.99 meters.
___
Rounded to the nearest tenth meter, it is 8.0 m.
Standard form Ax + By = C
so
<span>(y - y1) = m(x - x1)
</span>given (5, -7) and m = -1/5
so
y + 7 = -1/5(x - 5)
-5y - 35 = x - 5
x + 5y = -30
answer
d. x + 5y = -30
Subtraction:
2115 (20:15) - 0830 (8:30) = 20:75 - 8:30 = 12:45 P.m. = 1245
Hope it helped,
Happy homework/ study/ exam!
