The amount of drugs that will be left after 12 hours is 17.42 mg provided Sarah takes 550 mg of an antibiotic every hour.

Exponential decay can be described as a reduced amount of an original substance by a definite percentage over a period of time. It can be determined by using the formula:

[tex]\mathbf{y = a(1 - r)^t}[/tex]

where;

[tex]\mathbf{y = 550(1 - 0.25)^{12}}[/tex]

y = 17.42 mg

Therefore, we can conclude that the amount of drugs that will be left after 12 hours is 17.42 mg.

It's a cuboid

Volume:-

Answer:

The volume will be 13.8

which is not here

Step-by-step explanation:

Given :

breadth = 11/12 ft = 0.92 ft

height = 4 ft

length = 3 _ 3/4 ft = 3.75 ft

The volume of cuboid is l×b×h

=> 0.92 × 4 × 3.75

=> 13.8

subtract 3

Step-by-step explanation:

The numbers are getting lower in value as you go,

So that means it is a subtracting sequence,

Take the first two numbers and subtract them,

23 - 20 = 3

So now subtract 3 from the others and see if it works,

20 - 3 = 17

17 - 3 = 14

14 - 3 = 11

11 is the missing number

Yep, it works,

Hence the sequence is to subtract three.

Answer:

$13.96

Step-by-step explanation:

1st, we figure out how much it cost to make the quilt.  The thread cost $2.99.  She bought 3 yards of fabric for $9.35 per yard, so the fabric cost $9.35 x 3 = $28.05.

The quilt cost $28.05 + $2.99 = $31.04

Profit is sales price less the cost of the item.  It's the money left over.

Sales price $45.00 - cost $31.04 = $13.96 is her profit

The correct statement for the symbol of a radioactive nuclide is the number of neutrons present in the nucleus of each atom is 126.

Radioactive nuclide or radioisotope is a different species of chemical element which have a similar mass.

These elements have unstable nuclei, which waste energy by emitting radiation such as alpha, and beta-gamma rays.

Thus, the correct option is C, the number of neutrons present in the nucleus of each atom is 126.

Answer:

The Zero Product Property states that if the product of two numbers is zero, then at least one of the numbers is zero. In symbols, where a and b represent numbers, if ab=0, then a = 0 or b=0

Step-by-step explanation:

Answer:

The identity property of 0, also known as the identity property of addition, tells us that any number + 0 = the original number. Adding zero will not change the "identity" or value of the number you are adding it to. For example: 5 + 0 = 5.

6 + 0 = 6

1 + 0 = 1 ... etc.

Answer:

x > -12

Step-by-step explanation:

Think of X as 1, so its kinda like 1x, so (1x+4=5x). Times the 2, = 10x.

1. X + 4 = 5x

2. 5x · 2 = 10x

3. Place the variables, X > -12

Answer: X > -12

Answer:

Since its on a workbook, I think what your supposed to do for the shapes is measure the given side, say the line for the first question for a square was 2 inches, then you would have to put the rest of the sides 2 inches as well, paying attention to the angle measures.

each angle is 90° in a square, 120° for a hexagon, and the rest should hopefully be do-able.

Answer:

720
