The number of days required to build a house by 4 men which is made by 5 men is 48 days is 60 days.

<h3>What is the relation between work and time?</h3>

The total time taken is inversely proportional to the rate of work. If a unit of work is done in total n number of days, then the total work done in a day can is,

W=(1/n)

It would take 48 days for 5 men to build a house. Thus, the work done by one man in one day is,

W=1/(48*5)

W=1/240

Thus, one man take 240 days to build a house. The time it takes when only 4 men works to build the house,

t=240/4

t=60

Hence, the number of days required to build a house by 4 men which is made by 5 men is 48 days is 60 days.

Lea has 3/4 cup of laundry detergent left in detergent bottle. Each load of laundry requires 1/6 cup of detergent. How many load

Stells [14]

ANSWER

Lea can wash 4½ loads of laundry with the remaining detergent.

EXPLANATION

Quantity of detergent left
$= \frac{3}{4}$

Quantity required to watch each load
$= \frac{1}{6}$

Number of loads Lea can wash
$= \frac{3}{4} \div \frac{1}{6}$

We now simplify this by multiplying with the reciprocal

Number of loads Lea can wash

$= \frac{3}{4} \times \frac{6}{1}$

$= \frac{3}{2} \times \frac{3}{1}$

$= \frac{9}{2}$

$= 4 \frac{1}{2}$

Therefore Lea can wash 4½ loads of laundry with the remaining detergent.

PLEASE HURRY WILL GIVE BRAINLIEST A truck can be rented from Company A for $90 a day plus $0.30 per mile. Company B charges $70

rjkz [21]

Answer:

40 miles a day

Step-by-step explanation:

The difference in fixed charge is $20; the difference in mileage charge is $0.50 per mile. So it will take $20/$0.50 = 40 miles for the extra mileage cost to eat up the savings in fixed cost. At that mileage, both companies will charge the same amount:

A: 90 + 0.30·40 = 102

B: 70 + 0.80·40 = 102
