Hello!
1. To convert minutes to hours, we must multiply the number of minutes by 60, because that is how many minutes there are in an hour.
2. 1 pint = 16 ounces
16 × 8 = 128
Fernando bought 128 fluid ounces of milk.
3. 1 quart = 0.25 gallons
0.25 × 8 = 2
2 gallons are equivalent to 8 quarts.
4. Because when you divide 25 by 8, the result is greater than 3.
5. By dividing 6,400 by 2,000, because that is how you will find the exact equivalent of 6,400 pounds in tons.
7. 1 pound = 16 ounces
16 × 80 = 1,280
1,280 ounces is equivalent to 80 pounds.
9.
The missing value in the table is 918, because:
1 yard = 3 feet
3 × 306 = 918
306 yards = 918 feet
The answer is 10 cheese pizzas.
For every three pepperoni pizzas, you have two cheese pizzas.
You have 15 pepperoni pizzas, you divide it by three. You have five sets of three pizzas. Multiply each set by two, you have 10 cheese pizzas.
15 ÷ 3 = 5
5 · 2 =10

Answer:
The amount of the supplement in Niklas' body immediately after the 12th dose is 4.30 micrograms.
Step-by-step explanation:
Half life is the time required for an element to decay into half of its initial size. The supplement has a half life of 4 hours means that it decay to half of its size every 4 hours. Therefore there are 6 stages of division in a day.
i.e

The amount of the supplement in Niklas' body after the first dose (first day) can be determined by;
=
× 25
= 0.390625 micrograms
He used the supplement daily for 12 days (12th dose), but the amount of the supplement in his body immediately after the 12th dose would be;
amount in his body per day × number of period for complete decay
= 0.390625 × 11
= 4.296875
The amount of the supplement in Niklas' body immediately after the 12th dose is 4.30 micrograms. This is because immediately after the 12th dose, the supplement has not reach its half life.
