The true statements about the opposite of -12 are that the opposite of the opposite of -12 is -12 and -12 and its opposite are located the same distance from zero on a number line. The opposite of -12 is +12.
Explanation:In mathematics, the opposite of a number is also called its additive inverse, which is the number that, when added to the original number, will result in zero. −12 and its opposite, +12, are indeed located on opposite sides of zero on a number line, not on the same side. The second statement is true, the opposite of the opposite of −12 is indeed −12. The third statement is incorrect, the opposite of −12 is +12, not −112. The fourth statement is also true, −12 and its opposite are both 12 units away from zero on a number line, so they're at the same distance from zero.

Solve the following word problem. A man travels from Town X to Town Y at an average rate of 50 mph and returns at an average rate of 40 mph. He takes a 1/2 hour longer than he would take if he made the round trip at an average of 45 mph. What is the distance from Town X to Town Y?
______ miles
Distance from Town X to Town Y = 100 miles
Distance = Speed x Time
Speed while going = 50 mph , Speed while returning = 40 mph
Let the time taken while going = t hours
So, the time taken while returning = t + 0.5 hours
Distance while going = Distance while coming backSo, 50 t = 40 ( t + 0.5)
50 t = 40x + 20
50 t - 40 t = 10x = 20
10 t = 20
t = 20 / 10 = 2
Hence, distance = 50 t = 40 ( t + 0.5 )
= 50 x 2 ; or 40 x 2.5 = 100

The distance from Town X to Town Y is 180 miles. This is determined by setting up and solving an equation based on the given speeds and time difference.
Explanation:The subject of this question is Mathematics, specifically it is a problem in a genre called distance, speed, time problems. Let's denote the distance from Town X to Town Y as 'd' miles. The man covers this distance twice - once going and once coming back. The time he takes to travel from X to Y is d/50 and to travel back from Y to X is d/40.
So, the actual total time he spends travelling is (d/50 + d/40) hours. If he made the round trip at an average speed of 45 mph, he would take (2d/45) hours (distance = speed x time). Given that the actual journey took a 1/2 hour longer than this, we can create the following equation:
(d/50 + d/40) = 2d/45 + 1/2.
Solving this equation for 'd', we get d = 180 miles. So, the answer is that the distance from Town X to Town Y is 180 miles.

Sylvia is going to pick out a souvenir hat while she is on vacation. She knows the price of the hat will increase by 5% when she pays sales tax. She writes the expression h + 0.05h to find the total amount she will pay for the hat if it costs h dollars. Jin correctly writes another expression, 1.05h, that will also find the the total amount Sylvia will pay for the hat if it costs h dollars. Use the drop-down menus to explain what each part of Sylvia's and Jin's expressions mean.
Answer:
Step-by-step explanation:
Answer and step-by-step explanation:
Sylvia's expression is h+0.05h.
The variable h represents the cost of the hat.
0.05 represents the 5% sales tax; 5% = 5/100 = 0.05.
0.05h represents the amount of tax paid on the hat. To find a percent of a number, we multiply the decimal form of the percent by the original amount.
The total cost is given by h+0.05h.
Jin's expression is 1.05h.
The variable h represents the cost of the hat.
1.05 represents 100% of the cost of the hat plus the additional 5% tax; 100+5 = 105%; 105% = 105/100 = 1.05.
Together the total cost is given by 1.05h.

The population of a small town decreased from 983 to 901. What is the percent decrease, to the nearest tenth of a percent?
The population of the small town percent decreased by approximately 8.4%.
To find the percent decrease in the population of the small town, we can use the formula for percent decrease:
Percent Decrease = [(Initial Value - Final Value) / Initial Value] * 100
Given that the initial population was 983 and the final population was 901, we can plug these values into the formula:
Percent Decrease = [(983 - 901) / 983] * 100
Now, calculate the numerator:
Percent Decrease = [82 / 983] * 100
Divide and multiply:
Percent Decrease = 0.0835 * 100
Now, calculate the percent decrease to the nearest tenth of a percent:
Percent Decrease ≈ 8.4%
So, the population of the small town decreased by approximately 8.4%.

A hurricane has a large eye of about 80 miles. How many kilometers wide is the eye?
It is given that a hurricane has a large eye of about 80 miles.
We have to determine about how many kilometers wide is the eye.
Since 1 mile = 1.6 kilometers (approximately)
To convert the unit 'mile' into 'kilometer' ,
we have to multiply the given number by '1.6'.
So, 80 miles = [tex] 80 \times 1.6 = 128 [/tex] kilometers.
So, the hurricane eye is about 128 kilometers wide.
Final answer:
To convert 80 miles to kilometers, multiply by the conversion factor of 1.60934, resulting in an eye of the hurricane that is approximately 128.75 kilometers wide.
Explanation:
To convert the size of a hurricane's eye from miles to kilometers, we use the conversion factor that 1 mile is approximately equal to 1.60934 kilometers. If a hurricane has an eye that is about 80 miles wide, we need to multiply this distance by the conversion factor to obtain the width in kilometers.
Step-by-step Conversion:
Identify the width of the hurricane's eye in miles: 80 miles.
Use the conversion factor: 1 mile = 1.60934 kilometers.
Multiply the width in miles by the conversion factor to get the width in kilometers: 80 miles * 1.60934 km/mile = 128.7472 kilometers.
Therefore, the eye of the hurricane is approximately 128.75 kilometers wide.

From the sample space sequals={1, 2, 3, 4,..., 15} a single number is to be selected at random. given event a, that the selected number is even, and event b, that the selected number is a multiple of 4, find p(upper a vertial line upper ba∣b).
The probability of randomly selecting an even number given that the number is a multiple of 4, or p(A|B), is 1.
Explanation:The question is asking for the conditional probability p(A|B), meaning the probability of event A (number is even) given that event B (number is a multiple of 4) has already occurred. In this sample space, there are 8 even numbers {2, 4, 6, 8, 10, 12, 14, 16} and 4 multiples of 4 {4, 8, 12, 16}. Therefore, the probability of picking an even number out of the ones that are multiples of 4 is as follows:
First, determine the probability of event A within event B by dividing the number of favorable outcomes (even numbers and multiples of 4) by the total outcomes of event B. In this case, all multiples of 4 are even numbers, so there are 4 favorable outcomes.
Calculating p(A|B): Number of instances where A and B occur together / Number of instances where B occurs = 4 / 4 = 1
Therefore, the probability of randomly selecting an even number given that the number is a multiple of 4, p(A|B), is 1.
