Answer:
A.
Step-by-step explanation:
1/5 is a rational number so A is false. Just to prove this ill show every other answer is true.
B is true because rational; numbers have a repeating pattern while irrational do not.
C is true as any number not involving i is a real.
D is true as all integers have a repeating pattern if turned into decimal form.
Interest = 500 x .03 x 4
I = 60
Closing Balance = 500 (p) + 60 (1)
Closing Balance = 560
Answer:
V = 11
Step-by-step explanation:
All you have to do here is to multiply both sides of this equation by 13. This will eliminate the fractions. You'll be left with V = 11.
The first one (top left) is a function. Use the vertical line test, if a vertical line crosses the line drawn on the graph twice, then it's not a function.
Sound travels 10200m farther through stone in 17 seconds than through aluminium
Speed of sound in aluminium = 3100 m/s
The speed of sound in stone = 3700 m/s
Time taken = 17 minutes
Distance traveled = Speed x Time
Distance traveled by sound in aluminium in 17 seconds = 3100 x 17
Distance traveled by sound in aluminium in 17 seconds = 52700 m
Distance traveled by sound in stone in 17 seconds = 3700 x 17
Distance traveled by sound in stone in 17 seconds = 62900 m
Difference in the distance traveled = 62900 - 52700
Difference in the distance traveled = 10200 m
Sound travels 10200m farther through stone in 17 seconds than through aluminium
