Let's assume
x be the number of loads by land carriers
y be the number of loads by air carriers
so, maximum number of loads can be 150
total number of loads =(the number of loads by land carriers)+(the number of loads by air carriers)
so, we get
the mail is sent via ground in air each land carrier takes 2000 pieces per load
so, total number of pieces by land =2000x
each air carrier takes 1500 pieces per load the
so, total number of pieces by air =1500y
total number of pieces = (total number of pieces by land)+(total number of pieces by air)
now, we can plug values
total number of pieces =2000x+1500y
A mail distribution center processes as many as 175000 pieces of mail each day
so, we get
so, we get system of inequality as

Answer:
1 : √3 : 2
Step-by-step explanation:
In the special right triangle, 30°-60°-90° triangle:-
Opposite side < Adjacent side < Hypotenuse.
1. The smallest side is opposite to angle 30°, also called opposite side.
2. Adjacent side is √3 times smallest side.
3. Hypotenuse is 2 times smallest side.
So the ratios of sides would be as follows:-
Opposite : Adjacent : Hypotenuse
1x : √3x : 2x
1 : √3 : 2
Enter it into the app photomath, it shows you answer and steps.
First of all, as I told you a little while ago, here is the formula
that solves ALL probability problems. Memorize this:
Probability =
(number of different successful possibilities)
divided by
(total number of all possibilities).
There are 10 keys in the bag. The total number of possible results
of pulling out one key out is 10.
3 of the keys start the car. The other 7 keys don't.
What are the 'successful' possibilities ?
The question asks for the probability of pulling keys that DON'T work.
So for this particular calculation, we're talking about choosing keys
that DON'T work. There are 7 of those.
The probability of drawing a key that doesn't work the first time is 7/10 .
Since the first key is put back in the bag and the bag is mixed, the
situation on the second draw is exactly the same as on the first one.
Thje probability of drawing a key that doesn't work the second time is 7/10 .
The probability of both events happening is (7/10)x(7/10) = 49/100 = 49% .
