The mean weight of the packages is 2.5, so the total weight of the packages is found by multiplying 2.5 pounds by 4 which is equal to 10 pounds. That is the tial weight of the four books. To find the weight of the fourth book, the three other weights are subtracted from 10 pounds:
20.5 is the answer, have a great day!
Answer:
Confused as well
Step-by-step explanation:
If there are hypothetically 10 hours a day with 100 minutes an hour and 100 seconds per minute
at 6 pm there would be 18 hours gone in the day
18 normal hours are equal to 18*60*60 = 64800 seconds
(64800 seconds) / 10000 ( for hours)
6:48 would be the replacement time
but this answer is wrong bc it's not an option
Start with y=mx+b
B is your y intercept
m is your slope
The points you have are (-1,4) and (1,-2)
To find the slow you Do Y2-Y1/X2-X1
(-2-4)/ (-1-1)
-6/-2
your m is 3
Now you go back to the equation of a Line y=mx+b
to find b (your y intercept) take on of the two points, and substitute it's y value in the equation Let's take (1,-2)
Y=mx+b
-2=3(1)+b
-2=3+b
b=-5
you now know that
b=-5
m=3x
The equation is
y=3x-5
Answer:
b. $35.61
Step-by-step explanation:
First, convert the 25% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 25%) by 100%.So, the conversational term "25%" becomes 25% / 100% = 0.25 in terms of a real mathematical number.
Second, you need to find out what 25% of your $28.49 meal cost is.This is always done by multiplying 0.25 by $28.49, or
<h2> 0.25 x $28.49=$7.12.
</h2>
So, the amount of tip you are going to leave is $7.12.
This makes the total cost of your meal (to write on your charge slip or other payment)
<h2>
$28.49 + $7.12 = $35.61.
</h2>
