Answer:
1.12675hours approximately
Step-by-step explanation:
If the tub was 4.97 gallons it would take 1 minute Right?
To find the the time required to fill the tub divide volume of tub by the rate of hose. We have 336/4.97=67.605minutes
Divide by 60` 67.605/60=1.12675hours approximately
Answer:
Rs 17 3/4
Step-by-step explanation:
Cost of 6 1/2 m = 115 3/8
Cost of 1 m = x
- x = 115 3/8 ÷ 6 1/2
- x = (115*8 +3)/8 ÷ 13/2
- x = 923/8 × 2/13
- x = 923/(4*13)
- x = 923/52
- x = 17 39/52
- x = 17 3/4
Cost of 1 meter is Rs 17 3/4
Relatively prime means having no factors in common.
I will start by checking if they have the factor "3" in common: it's easy to check: the sum of its digit needs to be divisible by 3:
<span>a. 72 And 115
7+2=9
1+1+5=7
not true that both are divisible by 3
b. 120 And 835
1+2=3
8+3+5=16
</span>
<span><span>not true that both are divisible by 3
but, they're both divisible by 5! (0 or 5 at the end)
not relatively prime
</span> c. 201 And 735
2+1=3
7+3+5=15
both are divisible by 3!
d. 303 And 1041
3+3=6
1+4+1=6
both divisible by 3
the answer is a)
</span>
