Each day that a library book is kept past its due date, a $0.30 fee is charged at midnight. Which ordered pair is a viable

n200080 [17]

The equivalent equation to find the ordered pair will be y=0.3x where x represents the number of days the book is late and y represents the total fine fee.

A linear equation is an equation where the highest degree in the equation is 1.

for example, y=mx,

where y and x is the variable and m, is the constant.

Given, that the librarian charges $0.30 per each day that the book is late to submit

for estimating the relation between the number of days the book is late and the total fine fee

Let's assume the number of days the book is late is x,

and the total fine is y

the librarian charges $0.30 per one day

so for x days, the total charge will be =0.30x

so from above, it is clear that the linear equation will be

y=0.3x

applying all the order pairs in this equation we can decide.

The equivalent equation to find the ordered pair will be y=0.3x

<h3>Answer is -8</h3>

Work Shown:

y = -(2^x)

y = -(2^3) ... replace x with 3

y = -(2*2*2) ... expand out 2 cubed

Part c

ehidna [41]

The probability that the first slice of the cake will have the marble exists

7/66.

<h3>How to determine the probability using parts A and B?</h3>

Part A of the question demands that the volume of the cake be

estimated.

The volume of the cake exists, $$V=\pi(\frac{d}{2} )^{2} h \\$

$$&V=\pi(\frac{9}{2} )^{2} * 4$

$$V=81 \pi$

The part B of the question requires that the volume of each cut be

computed

The volume of each cut exists, V = 27

To estimate the required probability

We simply divide the volume of each cut by the volume of the cake.

$$P=\frac{27}{81 \pi}$

$$P=\frac{1}{3 \pi}$

Expand $\pi$

$$&P=\frac{7}{3 * 22} \\$

$$&P=\frac{7}{66}$

Therefore, the probability that the first slice of the cake will contain the

marble exists at 7/66.

Answer:

The best estimate of the probability of getting a green marble from this bag of 50 marbles is 1/3.

Step-by-step explanation:

Andre gets 1 green marble out of 4 trials.

For Andre, the probability of getting 1 green marble is 1/4.

Jada gets 5 green marbles out of 12 trials.

For Jada, the probability of getting 1 green marble is 5/12.

Noah gets 3 green marbles out of 9 trials.

For Noah, the probability of getting 1 green marble is 3/9.

Hence, the best estimate of the probability of getting a green marble from this bag = (1/4 + 5/12 + 3/9)/3 = [(9 + 15 + 12)/36]/3 = 1/3.

Given: BAD = CAD. Find the perimeter of ABC.

11111nata11111 [884]

Answer:

34 units

Step-by-step explanation:

Since the triangles are equal, the bottom length of triangle CAD will be the same as the bottom length of BAD. This means that the total length of the bottom of triangle ABC is 6 (3 + 3).

Next, you need to find the length of AC and again, since they're the same triangle, AB will be the same as AC, 14.

The three side lengths of the triangle will be 6, 14, and 14, so the perimeter is

6 + 14 + 14 = 34 units
