Angle relationships with Parallel lines

Andrea arrived 5 minutes past 11:00 am, or at 11:05 am. Adding the 8 minutes indicated on her card, we get 11:13 am as the time Andrea arrived.

Let x be the number of minutes past 11:00 am that Andrea arrived. Then, Zach arrived (x + 15) minutes past 11:00 am. Two minutes ago (i.e., at 11:28 am), Andrea had been waiting for (28 - x) minutes, and Zach had been waiting for (13 + x) minutes. Three minutes from now (i.e., at 11:33 am), Andrea will have been waiting for (33 - x) minutes, and Zach will have been waiting for (18 + x) minutes. Since Andrea and Zach have waited for the same amount of time, we can set up the equation:

Solving for x, we get:

2x = 10

x = 5

Therefore, Andrea arrived 5 minutes past 11:00 am, or at 11:05 am. Adding the 8 minutes indicated on her card, we get 11:13 am as the time Andrea arrived.

The value of angle S is 53°

Exterior angle theorem states that the measure of an exterior angle of a triangle is equal to the sum of two remote interior angles.

With this theorem we can say that

7x+2 = 4x+13+19

collecting like terms

7x -4x = 13+19-2

3x = 30

divide both sides by 3

x = 30/3

x = 10

Since x = 10

angle S = 4x+13

angle S = 4(10) +13

= 40+13

= 53°

Therefore the measure of angle S is 53°

The complete question is shown below:

Lynn is at a store and wants to buy a new backpack that costs $55. she only has $35 with her, but she has the rest at home. Lynn also has a credit card that does not charge her any interest if she pays the balance in full by the end of the month. why might Lynn want to wait until she has $55 in cash at the store to purchase the backpack, instead of using her credit card?

a. Using a credit would cause the store to lose money because even if she pays back her bill in full, she will still need to pay the credit card company additional dollars for the convenience of borrowing money.

b. Using cash would cause the store to lose a large amount of money because credit card companies offer incentives to stores based on the number of people who use their cards.

c. She might forget to pay the credit card bill, which would make her purchase more expensive due to interest payments and late charges.

d. She would likely have to pay more than $55 at the time of purchase for the convenience of using her credit card.

Step-by-step explanation:

I'm not sure if this are right

the probability that the diameter of a elected bearing is greater than 85 millimeter P(diameter > 85) = P(z > (85-81)/4) = P(z > 1) = 0.1587

The diameter of ball bearings is normally distributed, with a mean of 81 millimeters and a variance of 16.

To calculate the probability that a selected bearing has a diameter greater than 85 millimeters, we first calculate the z-score for 85 millimeters.

We subtract 81 from 85 to get 4, and divide by 4 to get 1 for the z-score.

We the look up the probability for a value of 1 in the z-table, which is 0.1587.

This is the probability that a selected bearing has a diameter greater than 85 millimeters, rounded to four decimal places.

The equation in polar coordinates is: r = 19 / cos(θ)

To convert x = 19 to an equation in polar coordinates, we need to use the relationships between rectangular and polar coordinates:

x = r cos(θ)

where r is the distance from the origin to the point (x, y) and θ is the angle that the line connecting the origin and the point makes with the positive x-axis.

To solve for r, we can rearrange the equation as:

r = x / cos(θ)

Substituting x = 19 and recognizing that cos(θ) is the same for all values of θ at a given distance from the origin, we get:

r = 19 / cos(θ)

So the equation in polar coordinates is:

r = 19 / cos(θ)

where r is the distance from the origin to the point (x, y) and θ is the angle that the line connecting the origin and the point makes with the positive x-axis.

The probability that the sample of three apples contains two rotten apples is approximately 0.0286 or 2.86%.

To find the probability that the sample of three apples contains two rotten apples, we can use the hypergeometric distribution.

The number of ways to choose 3 apples from the basket of 15 apples is given by the combination formula:

C(15, 3) = 15! / (3! * 12!) = 455

The number of ways to choose 2 rotten apples from the 2 rotten apples in the basket is C(2, 2) = 1.

The number of ways to choose 1 good apple from the 13 good apples in the basket is C(13, 1) = 13.

So the number of ways to choose 2 rotten apples and 1 good apple from the basket is C(2, 2) * C(13, 1) = 13.

Therefore, the probability of selecting a sample of three apples that contains two rotten apples is:

P(2 rotten apples) = 13 / 455 = 0.0286 (rounded to four decimal places)

So the probability that the sample of three apples contains two rotten apples is approximately 0.0286 or 2.86%.
