A patients IV bag contains 750mL. Four hours later, the IV bag contains 450mL.
a) Determine the rate at which the bag is draining.
b) Use your answer from (a) to predict how many mL of IV fluid are left in the bag after 6 hours.
(a) The rate at which the bag is draining is 75mL/h.
(b) After 6 hours, the remaining fluid is =0 mL.
What is rate?Rate is a measurement of change of a quantity with respect to another quantity.
Given that,
Initial volume of bag=750 mL,
After 4 hours later, the volume of bag= 450.
(a)
To determine the rate of draining,
The change of volume in 4 hours= 750-450=300
The change of volume in 1 hour = 300/4=75
So, the rate of draining= 75mL
(b)
To determine the remaining volume of bag after 6 hours,
The volume drains in 1 hour=75 mL
The volume drains in 6 hours = 75×6=450
The remaining fluid = 450-450=0
The fluid remains after 6 hours is 0mL.

Answer:
178
Step-by-step explanation:
All right!!
Line l is parellel to line m.
So if r is 91 then we can infer that s helps it make a 180 degree angle/straight line.
So 180 - 91 = 89
s = 89
If the two lines are parallel then s = u because of inner angles/outer angles stuff.
If s=u then u = 89 as well.
And because of vertical angles, t =u so t = 89.
Now the question asks to find t + u, so t + u = 89 + 89 = 178

To mail a letter to Vienna, Austria the post office charges a flat rate of $8.00 and an additional $0.50 for every ounce the letter weighs. The cost of mailing a letter is determined by the equation y=0.50x+8.00, where y is the cost of the postage and x is the weight of the letter in ounces.
Step 2 of 2 : Use the graph to estimate to the nearest quarter of a dollar ($0.25) the cost to send a letter that weighs 3 ounces.
Answer:
It will cost 38 quarters
Step-by-step explanation:
y = 0.50x + 8.00
y = 0.5(3) + 8.00
y = 1.5 + 8.00
y = $9.50
$9.50/.25
38 quarters

Which expression has the sum of twenty six twentieths?
two fifths plus four tenths
four fifths plus two fourths
one half plus three tenths
three fourths plus two fifths
b. four fifths plus two fourths
Step-by-step explanation: Change the fractions to their equivalents in 20ths-- like finding the common denominator.
Divide the original denominator into 20, then multiply the result by the original numerator to get the new numerator.
4/5 20/5 = 4 4×4 = 16 so 4/5 is equivalent to 16/20
2/4 20/4 = 5 5×2 = 10 so 2/4 is equivalent to 10/20
Add: 16/20 + 10/20 = 26/20

sara buys two bags of chips and three boxes of pretzels for $ 85. He then buys another bag of chips and two more boxes of pretzels for $ 50. Find the cost of each bag of chips and each box of pretzels.
Answer:
Chips= $20 Pretzel=$15
Step-by-step explanation:
Sara bought 2 Chips + 3 Pretzels = $85
(Extra) 1 Chips + 2 Pretzels = $50
Pretzels are twice as much as chips so above ^^ Can be expressed
as Pretzel (15) + Pretzel (15) + Chips(20) = $50
Now lets go back to the first line Putting in the new prices
Chips(20) + Chips(20) + Pretzel(15) + Pretzel(15) = Pretzel(15) = $85
8.5x-y= 16
O -y= 5x + 16
O x=5y-16
O y= 5x +16
O y= 5x- 16
Answer:
y = 5x - 16
Step-by-step explanation:
1. To solve this question, we must convert 5x - y = 16 into slope-intercept form (y = mx + b).
2. (Solving for y)
Step 1: Subtract 5x from both sides.
[tex]5x - y - 5x = 16 - 5x[/tex] [tex]-y = -5x +16[/tex]Step 2: Divide both sides by -1.
[tex]\frac{-y}{-1} =\frac{-5x+16}{-1}[/tex] [tex]y = 5x - 16[/tex]Therefore, the answer is y = 5x - 16.
