Final answer:

The process of finding the surface area of a rectangular prism is similar to finding the surface area of a triangular prism. Both involve drawing a net and adding the areas of the faces. However, the formulas used are different because the shapes have different types of faces.

Explanation:

For both prisms, you can draw a net to help you find the areas of the faces. Add the areas together to find the surface area. A rectangular prism has only rectangular faces, and you use the formula bh to find area. A triangular prism has triangular and rectangular faces, and you use the area formula bh for rectangular faces and the area formula 1/2bh for triangular faces.

She can withdraw all $6000 and not have to pay anything.

Lilly will not have to pay any taxes when she withdraws the entire $6000.

Option B is the correct answer.

The percentage means the required value out of 100.

It is calculated by dividing the required value by the total value and multiplying it by 100.

The percentage change is also calculated using the same method.

In percentage change, we find the difference between the values given.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

We have,

Since Lilly deposited $3000 into a Roth IRA, that means she had already paid taxes on that money before depositing it.

Therefore, when she withdraws the entire $6000, she will not have to pay any taxes on the original contribution of $3000.

Now,

For the remaining $3000 (the growth), she will also not have to pay any taxes since Roth IRA withdrawals of earnings are tax-free if the account holder is over 59½ and the account has been open for at least five years.

Therefore,

Lilly will not have to pay any taxes when she withdraws the entire $6000.

Answer:

A. 54.28 ft^2

Step-by-step explanation:

Area of the parallelogram = 48 ft^2

Area of the semicircles = 6.28 ft^2

A = π r^2

A = 3.14 (2)

A = 3.14 (4)

A = 12.56

12.56 ÷ 2 = 6.28 ft^2

48 + 6.28 = 54.28 ft^2

Answer:

D. 88 inches

Step-by-step explanation:

to get the circumference of a circle the equation is C=2πr

C=87.96

Final answer:

Every time Micah's wheel turns one full rotation, the bicycle would travel approximately 88 inches.

Explanation:

The student's question relates to the travel distance of a bicycle wheel in one full rotation.

The distance traveled by a wheel in one rotation is equal to the circumference of the wheel, which is calculated by the formula:

Circumference = 2π × radius.

Given Micah's bicycle wheel has a radius of 14 inches, the calculation would be:

Circumference = 2 × π × 14 inches

Circumference = 2 × 3.1416 × 14 inches

Circumference ≈ 88 inches

Therefore, every full rotation of Micah’s 14-inch-radius bicycle wheel will result in the bicycle traveling approximately 88 inches, which is the circumference of the wheel.

Answer:

The correct option is D (-∞,-3)∪(-1,1)

Step-by-step explanation:

Given,

[tex]\frac{x^{2}-1 }{3x+9}[/tex] ≤ 0

To find the solution.

The solution could be found if

[tex]x^{2} -1[/tex] ≤ 0           and

3x+9 ≠ 0 [if the denominator is 0, it gives ∞ as solution]

Now,

[tex]x^{2} -1[/tex] ≤ 0

or, (x+1)(x-1) ≤0

or, x ≤1 and x≤-1

Both of the above condition holds is x≤1

Again,

3x+9≠0

or, x≠-3

All the conditions gold for the values (-∞,-3)∪(-1,1)

Hence the correct option is D.

Answer: 39 miles

Step-by-step explanation:

Hi, since the travelling forms a right triangle, (see attachment) we have to apply the Pythagorean Theorem formula.

a^2 +b ^2 =c ^2

Answer:

Probability of a train on line A arriving on time: 80%

Probability of any train arriving on time: 96%

Step-by-step explanation:

If 18 of the 90 incoming trains on line A arrive late, we have that 90 - 18 = 72 trains of the 90 arrive on time, so the probability of a train on line A arriving on time is:

P(A) = 72/90 = 0.8 = 80%

on line B, we have that 70 - 14 = 56 trains of the 70 arrived in time, so the probability of a train from line B arriving on time is:

P(B) = 56/70 = 0.8 = 80%

To find the probability of any train arriving on time, we can use this formula:

P(A or B) = P(A) + P(B) - P(A and B)

P(A or B) = 0.8 + 0.8 - 0.8*0.8

P(A or B) = 1.6 - 0.64 = 0.96 = 96%

The probability that a train on line A arrives on time is 0.8 or 80%. The probability that any train arrives on time, considering both line A and line B, is also 0.8 or 80%.

To calculate the probability that a train on line A arrives on time, we subtract the number of trains that arrive late from the total number of trains on line A:

Probability = (Total trains on line A - Trains on line A that are late) / Total trains on line A

Probability = (90 - 18) / 90

Probability = 72 / 90

Probability = 0.8 or 80%

To calculate the probability that any train arrives on time at the station, we need to consider the total number of trains arriving on time for both lines:

Total trains on time = (Total trains on line A - Trains late on line A) + (Total trains on line B - Trains late on line B)

Total trains on time = (90 - 18) + (70 - 14) = 72 + 56 = 128

Then, we divide the number of trains on time by the total number of trains:

Probability = Total trains on time / Total trains

Probability = 128 / (90 + 70)

Probability = 128 / 160

Probability = 0.8 or 80%

This question is a combination of English alphabet and mathematics in the context of a math escape room. You're asked to provide three things (possibly answers from different problems) and then write those in capital letters and in alphabetical order, without spaces or commas. For instance, if your answers were DOG, CAT, and BEE, you would write BEECATDOG.

The answer to this question is a bit unique as it involves both math and the English alphabet. The hint is to write a response in alphabetical order without spaces or commas and in all capitals. Given that these are the constraints, we must first figure out what those three things to write in our response are based on the math problem, and then list them in alphabetical order. Knowing that it's an escape room for your math class, perhaps these could be answers from past or current problems in your class.

Answer:

[tex]\sin F =\dfrac{12}{37}[/tex]  

Step-by-step explanation:

We are given the following in the question:

GF = 37 units

HG = 12 units

FH = 35 units

We have to find the ratio that represents sine of ∠F.

Formula:

[tex]\sin F = \dfrac{\text{Perpendicular}}{\text{Hypotenuse}}\\\\\sin F = \dfrac{HG}{GF}=\dfrac{12}{37}[/tex]

is the required ratio of sine of ∠F.

The attached image shows the triangle.

In the right triangle ΔFGH, the sine of ∠F is represented by the ratio of the opposite side (HG) to the hypotenuse (FH), so the sine of ∠F is 12/35.

In the right triangle ΔFGH, the sine of an angle is defined as the ratio of the length of the opposite side to the length of the hypotenuse. Considering ∠F, the side opposite to it would be HG and the hypotenuse in this scenario would be FH.

Given that HG = 12 and the length of the hypotenuse FH = 35, then the sine of ∠F (sin F) would be represented by the ratio 12/35.

Therefore, the sine of ∠F in the triangle ΔFGH is 12/35.

Answer:

The distance the tornado traveled was approximately 205 miles.

Step-by-step explanation:

The equation representing the relationship between the wind speed (in miles per hour) and the distance the tornado travels (in miles) is:

[tex]s=93\log d+65[/tex]

Compute the value of d for s = 280 as follows:

        [tex]s=93\log d+65[/tex]

     [tex]280=93\log d+65[/tex]

[tex]93\log d=280-65\\93\log d=215[/tex]

   [tex]\log d=2.312\\[/tex]

        [tex]d=10^{2.312}\\d=205.035\\d\approx 205[/tex]

Thus, the distance the tornado traveled was approximately 205 miles.
