Answer:
45.7 s
Step-by-step explanation:
Darya:
Number of laps = 13
Average time per lap = 23.5 seconds
Total time to swim 13 laps = Number of laps × Average time per lap
= 13 × 23.5
= 305.5 seconds
Kana:
Number of laps = 10
Average time per lap = 25.98 seconds
Total time to swim 10 laps = Number of laps × Average time per lap
= 10 × 25.98
= 259.8 seconds
It took longer for Darya to swim
13 laps than for Kana to swim 10 laps.
How much longer?
= 305.5 seconds - 259.8 seconds
= 45.7 seconds
Answer:
117 - 10x
Step-by-step explanation
I'm sorry i don't remember the correct explanation but you must simplify each term I had this question on a quiz and got it correct .
Answer: The factors of 98 are 1, 2, 7, 14, 49, 98
Step-by-step explanation:
1 x 98 = 98, 2 x 49 = 98, 7 x 14 = 98, 14 x 7 = 98, 49 x 2 = 98
Hope this helps fren <3
Answer:
The answer is given below
Step-by-step explanation:
The loads in the circuit are continuous duty, so the circuit can only loaded to 80% of its current rating.
Calculate 80% current rating of the circuit breaker.
Icb = [ 80/100] (20 A)
= (O.8) (20 A )
= 16 A
Now we assume that the value of supply voltage is 120 V
Now we will calculate current flows via under water light which will be taken as Load 1
<em>Ii = </em>500 W/120 V
= 4.167 A
Current via the circulating pump which will be taken as Load 2 IS 8.5 A
<em>I = </em>load1 + load 2
<em> = 4.167 A + 8.5 A</em>
<em> = 12.67 A</em>
The total current in the circuit obtained which is less than the circuit breaker rating current. Therefore, the power can be operated for both the loads.
Answer:
2167.7 sq yds
Step-by-step explanation:
SA(cone) = πr² + πrs ('s' = slant height)
= π(15)² + π(15)(31)
= 225π + 465π
= 690π
= 2167.7
