Answer:
During 15 hour period, 1409.7 mg of dextrose will be delivered.
The flow rate of dextrose per hour will be 93.98 mg/hour.
Step-by-step explanation:
If a total of 3.81 liters of the solution is given over a 15 hour period.
Now, 1 liter is equivalent to 1000 ml
So, a total of 3810 ml of the solution is given over a 15 hour period.
If 100 ml of solution contains 37 mg of dextrose, then 3810 ml of the solution will contain
mg of dextrose.
So, during the 15 hour period, 1409.7 mg of dextrose will be delivered.
The flow rate of dextrose per hour will be
mg/hour. (Answer)

- Multiply x-1 on both sides







Now
ATQ to the equation
x should be greater than 1 .Because if it becomes 1 then the denominator will be 0 which is impossible.
Hence x>1
Thus

Now

Answer:
1)
.
2) 
hence, answer is 7/12.
3) We have to divide £72 in the ratio 2:3:1
the total of the ratio is=2+3+1=6
so on dividing 72 into 6 parts we have 72/6=12
First '2' parts=2×12=24
second '3' part=3×12=36
last '1' part=1×12=12
so dividing £72 in the ratio 2:3:1 is: £24,£36 and £12
4) 39 people out of 65 have blonde hair.
Number of people who do not have blonde hair=65-39=26
percentage people who do not have blonde hair is given by:

Hence, percentage people who do not have blonde hair is 40%
5) 20% of 90= (20/100)×90
=18
Hence, 20% of 90 is 18.
6) Factorise

7) Expand

8)
.
9)

10)

11) x= -4 y=3
and z=4 x-y^3
z=4×(-4)-3^3
z= -43
12) 
13) 
Hence x= -2
14) 5,10,15,20,....
Hence, nth term is 5n.
15) (63×128)/32.9=245.106.
16) 938×21=19698.
Answer:
When ordering fractions, you don't only have to take in account for the numerator, you also have to take into account the denominator, whereas with whole numbers, you only have to take into account the numerator. Also, in a fraction, you have to make sure the denominators are the same before ordering them.
Answer:
1.2Litres
Question:
Wes mixed different juices to make fruit punch. He filled one-half of the punch bowl with orange juice. Then he filled half of the remaining space with grape juice. Finally, he filled the rest of the punch bowl with 300 mL300\text{ mL}300 mL300, space, m, L of cherry juice. How many liters of fruit punch did Wes make?
Step-by-step explanation:
Let the total punch bowl be = P
Portion of Orange juice = ½ of total punch bowl
= ½ × P = P/2
Portion of grape = ½ of the remaining space
Remaining space = P - P/2 = P/2
Portion of grape = ½ × P/2 = P/4
The rest of the punch bowl is for cherry = 300mL
P/2 - P/4 = 300
(2P - P)/4 = 300
P/4 = 300
P = 300×4
P = 1200mL
1mL = 10^(-3)L
P = 1.2 ×10³ × 10^(-3)L
P = 1.2L
Wes made 1.2liters of fruit punch.
