Answer:

There will be 18 grams left after 12 hours.

Step-by-step explanation:

Half-life is the amount of time it take for a cell to turn from one condition to another.

To find the amount of grams for the first 6 hours.

72 ÷ 2= 36

Now, since 6 x 2 = 12, we need to divide 36 by 2 to find the next half-life.

36 ÷ 2 = 18

Therefore, there will be 18 grams left after 12 hours.

Answer:

m<4 = 44°

Step-by-step explanation:

m<8 = 34°

m<9 = 40°

m<3 = 62°

m<2 = 34° + 40° (exterior angle theorem of a triangle)

m<2 = 74°

m<3 + m<4 + m<2 = 180° (sum of ∆)

62° + m<4 + 74° = 180° (substitution)

m<4 + 136° = 180°

m<4 = 180 - 136 (substitution property of equality)

m<4 = 44°

The required equation which represents the expression of Celsius temperature as a linear function of the Fahrenheit temperature is; C = (9/5)F - 57.6.

It follows from the task content that the linear equation which relates both the Celsius and Fahrenheit temperature is to be determined.

On this note, the two points which can be inferred to describe the linear relationship are;

(32, 0) and (212, 100)

Hence, the slope of the linear equation;

m = (C2 - C1)/(F2 - F1)

m = (212 - 32)/(100 - 0)

m = 180/100

m = 9/5

Hence, from the point-slope equation form; (y-y1) = m (x -x1).

We have; (C - 0) = (9/5) (F - 32)

C = (9/5)F - 57.6

Explanation:

I recommend drawing out the number line. Plot -16 and 14 on it.

Either count out the spaces, or subtract and apply absolute value, to find the distance from -16 to 14 is exactly 30 spaces.

----------

Or you can think of it like this:

From -16 to 0 is 16 spaces

From 0 to 14 is another 14 spaces

That's 16+14 = 30 spaces total.

----------

In short, segment CD is 30 units long.

Point E is somewhere on segment CD.

x = distance from E to C

y = distance from E to D

x+y = EC+ED = CD = 30

x+y = 30

y = 30-x

We're told the distance from E to C is 1/4 the distance from E to D, so,

x = (1/4)*y

x = (1/4)*(30-x)

x = 0.25*(30-x)

x = 7.5 - 0.25x

x+0.25x = 7.5

1.25x = 7.5

x = (7.5)/(1.25)

x = 6

The distance from E to C is 6 units.

This means we'll add 6 units to the location of point C to find out where to place E

E = C+6 = -16+6 = -10 is the final answer

Answer:

Oy=2x+3

Step-by-step explanation:

The function that has the {y} - intercept as that of the function graphed is y = 2x + 3

A function is a relation between a dependent and independent variable. We can write the examples of functions as -

y = f(x) = ax + b

y = f(x, y, z) = ax + by + cz

Given is to find the linear function that has the same y-intercept as the one that is represented by the graph.

The function graphed has the {y} - intercept of 3.

For the functions given -

Functions              {y} - intercept

y=2x-4                        -4

y=2x-3.                       -3

y=2x+3                        3

y=2x+4                        4

So, the function that has the {y} - intercept of 3 is y = 2x + 3.

Therefore, the function that has the {y} - intercept as that of the function graphed is y = 2x + 3.

Answer:

The largest advertisement she can afford has dimensions of 5 in x 10/3 in

Step-by-step explanation:

Assume the dimensions of the advertisement are L and W.

The area of the advertisement is:

A = L.W

The ratio length/width is 3:2, thus the proportion is:

[tex]\displaystyle \frac{L}{W}=\frac{3}{2}[/tex]

Thus:

[tex]\displaystyle L=\frac{3}{2}W[/tex]

The area is:

[tex]\displaystyle A=\frac{3}{2}W^2[/tex]

Since the square inch of advertisement space sells for $3, the cost for Anna to purchase it is:

[tex]\displaystyle C=3\cdot\frac{3}{2}W^2[/tex]

Simplifying:

[tex]\displaystyle C=\frac{9}{2}W^2[/tex]

This cost can be a maximum of $50, thus:

[tex]\displaystyle \frac{9}{2}W^2=50[/tex]

Multiplying by 2:

[tex]9W^2=100[/tex]

Solving for W:

[tex]\displaystyle W=\sqrt{\frac{100}{9}}=\frac{10}{3}[/tex]

[tex]\displaystyle W=\frac{10}{3}[/tex]

And

[tex]\displaystyle L=\frac{3}{2}\cdot \frac{10}{3}[/tex]

L = 5

Thus the largest advertisement she can afford has dimensions of 5 in x 10/3 in

There are three pairs of faces with surface areas of 75.3 square inches, 111.384 square inches and 35.818 square inches.

The surface area of the six faces of the parallelepiped is equal to 444.956 square inches.

The real surface area is between 214.9 square inches and 668.3 square inches.

The mistaken surface area found by Jayden is 443 square inches.

In this problem we find a right angled parallelepiped whose dimensions are known. The surface area of the parallelepiped is the sum of the areas of the six faces. There are three pairs of faces with the following dimensions:

Pair 1

A' = (4.92 in) · (15.3 in)

A' = 75.276 in²

Pair 2

A'' = (15.3 in) · (7.28 in)

A'' = 111.384 in²

Pair 3

A''' = (4.92 in) · (7.28 in)

A''' = 35.818 in²

There are three pairs of faces with surface areas of 75.3 square inches, 111.384 square inches and 35.818 square inches.

The surface area of the six faces of the parallelepiped is equal to 444.956 square inches.

The range of measures for the area of the parallelepiped is represented by the following inequality:

6 · 35.818 in² < 444.956 in² < 6 · 111.384 in²

214.908 in² < 444.956 in² < 668.304 in²

The real surface area is between 214.9 square inches and 668.3 square inches.

Lastly, the mistaken surface area found by Jayden is:

A = 2 · (4.92 in) · (15.1 in) + 2 · (111.384 in²) + 2 · (35.818 in²)

A = 442.988 in²

The mistaken surface area found by Jayden is 443 square inches.

♡ Answer ♡

G) 1/12

♡ Step-by-step explanation ♡

  In order to figure out this problem, we have to take a few relatively simple steps.

  First, we must count the total number of coins in the cash register. Do not change the value of these coins. Simply take the numbers listed in the problem and add them up. Your process for completing this step should look something like this: 10+11+13+6 equals 40. With this being said, there are 40 coins in the cash register.

  Next, we must remember the values of the two coins the question is asking for: pennies and dimes. Keep in mind that, out of all 40 coins, 10 of them are pennies and 13 of them are dimes.

  Then, we write the fractions used to find the answer to this problem. In the question, the cashier (hypothetically) draws a penny first, and then a dime. This means a penny is drawn before a dime is drawn. (Although it seems like a miniscule detail, this knowledge is actually something extremely important to remember. This small piece of information can actually change the entire answer if not used properly.)

  In this problem, the cashier would choose a single penny out of the 10 in contrast to the total 40 coins. Since there are 10 pennies overall, and 40 coins overall, the probability of choosing a penny first is 10/40.

  After we complete the probability of choosing a penny before all else, we must find the probability of choosing a dime after choosing a penny. Since the dime will be chosen after the penny is chosen, one coin will be gone: the chosen penny. So, the total amount of coins within the cash register changes (or more specifically decreases (by 1)) from 40 to 39. However, the amount of dimes, 13, stays the same. With this information in mind, we can write a fraction of 13/39 for the probability of choosing a dime after choosing a penny.

  Finally, now that we have both probability fractions, we can figure out the answer to the question. In order to do this, we multiply and simplify both fractions. 10/40*13/39 is 130/1560. 130 ÷ 130 is 1. 1560 ÷ 130 is 12. 1 ÷ 12 can also be written as 1/12. Therefore, the answer to this problem is G) 1/12.

(The paragraph and author's note below are technically optional thought processes and information, but read them if you wish. Although I would recommend reading further, considering another way to solve the question is mentioned, it is entirely you (the reader's) choice.)

  You can also check this answer through the other/alternate way of solving this problem: by simplifying both probability fractions before you multiply them. 10/40 can be simplified to 1/4. 13/39 can be simplified to 1/3. After doing this, we multiply both simplified probability fractions in order to find, or in this case check, the answer. 1/4*1/3 is 1/12. 1/12 is the same fraction as the one present in choice G. This is the same answer as the one we previously got. This enforces the idea that G) 1/12 is indeed the answer to this question.

  A/N (Author's Note): Although it took quite a while to jot down, this was truly a blast to write and explain! I hope this helped those that needed/wanted it. Have a wonderful week reader(s)!
