Answer:
2 people will take 90 days to complete the same house
Step-by-step explanation:
<u><em>Given:</em></u>
T1 = 30 days
P1 = 6
T2 = x
P2 = 2
This is an inverse proportion because if there are more people, less time will be taken to complete the house and vice versa.
<u><em>So, We'll write it in the order of :</em></u>
=> T1:T2 = P2:P1
=> 30:x = 2:6
<u><em>Writing in fraction form</em></u>
=>
<em>Cross Multiplying</em>
=> 2x = 180
<em>Dividing both sides by 2</em>
=> <u><em>x = 90 days</em></u>
So, <u><em>2 people will take 90 days to complete the same house</em></u>
Answer:
This is very unclear however if your miles are 214 and you need 1% of the miles you can multiply it by 0.01 and the answer would be 2.14 miles
Answer:
Product before increasing: 4200
x after increase: 60 * 105% = 63
y after increase: 70 * 110% = 77
Product after increasing: 4851
Percentage increase in the product: 4851 / 4200 * 100 = 115.5%

9(3)=27+12=39=c
9(4)=36+12=48=c
57=9p+12
-12 -12
45=9p
divide by 9 both sides 45/9=5=p
c=9(6)+12
c=54+12
c=66
