If 5 men or 7 women can earn $315 in a day, find how much 7 men and 11 women can earn in three days ?

2808

Step-by-step explanation:

If 5 men can earn 315 dollars in a day then each of them can earn 63 dollars per day. If 7 women can earn 315 dollars in a day then each of them can earn 45 dollars per day. 7*63=441  11*45=495

441+495=936  But we aren't done yet! We only calculated the amount of wage 7 men and 11 women can earn in 1 day. So, to find out how much they earned in 3 days we have to multiply by 3

936*3=2808

So the answer is 2808 dollars.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
