The hard drive on your computer has a capacity of 160 gigabytes (GB). You have used 122 GB. You want to save some home videos to your hard drive. What are the possible sizes of the home video collection you can save? If u represents the amount of space used, write an inequality that determines a, the amount of space available.
To determine the size of the home video collection one can save, subtract the used space (122 GB) from the total hard drive capacity (160 GB). The remaining space is 38 GB, which is the maximum size for the home videos that can be saved. The inequality representing the available space in terms of 'a' is: a ≤ 38 GB.
Explanation:The subject of this question is a practical application of mathematics related to computer storage space.
If the computer's hard drive has a total capacity of 160 GB and you have already used 122 GB, we can determine the remaining available space with a simple subtraction: 160 GB - 122 GB = 38 GB.
So, the size of the home video collection that you can save cannot exceed 38 GB.
To represent this as an inequality where u is the amount used, and a is the amount available, we can write:
u + a ≤ 160 GB
Since you've used 122 GB already, the inequality in terms of a alone is:
a ≤ 160 GB - 122 GB
a ≤ 38 GB
This inequality states that the amount of additional data (home videos) you can save, denoted as a, should be less than or equal to 38 GB, which is the available space remaining on your hard drive.
Final answer:
To determine the available space on your hard drive, subtract the amount used from the total capacity. The possible sizes of the home video collection you can save range from 0GB to a maximum of 38GB. The inequality a ≤ 38GB represents the amount of space available.
Explanation:
To determine the amount of space available, you subtract the amount of space used from the total capacity. In this case, the total capacity is 160GB and the amount used is 122GB, so the amount of space available is 160GB - 122GB = 38GB.
Therefore, the possible sizes of the home video collection you can save range from 0GB (if you don't save any videos) up to a maximum of 38GB (if you save videos that take up the entire available space).
The inequality that represents this is: a ≤ 38GB, where 'a' represents the amount of space available.

Make t the subject of the formula
v = u + 5t
[tex]v = u + 5t\\\\5t=v-u\\\\t=\dfrac{v-u}{5}[/tex]
To make t the subject of the formula v = u + 5t, subtract u from both sides and divide by 5.
Explanation:To make t the subject of the formula v = u + 5t, we need to isolate t on one side of the equation.
First, subtract u from both sides of the equation: v - u = 5t.
Then, divide both sides of the equation by 5: (v - u)/5 = t.

There are 8 people who are attending a speed dating event. Each person has the chance to spend 5 minutes on a speed date, getting to know all of the other people at the event. How many unique speed dates will there be? Please help!!!
i think there should be 8 factorial. that is, 8 times 7 times 6 times 5 times 4...
There will be 28 unique speed dates in total.
Explanation:In this speed dating event, there are 8 people who each have the chance to go on a speed date with every other person at the event. Since there are 8 people, there will be 8 - 1 = 7 speed dates for each person.
To find the total number of unique speed dates, we can use the formula n * (n - 1) / 2, where n is the number of people. Plugging in 8 for n, we get (8 * 7) / 2 = 28. So, there will be 28 unique speed dates in total.

Answer:
[tex]\frac{9}{16}[/tex] cups of raisins are in each serving
Step-by-step explanation:
Unit rate defined as the rates are expressed as a quantity as 1 such as 2 meter per seconds or 4 miles per hour.
As per the statement:
The bake star bakery uses 2 1/4 cups of raisins to make 4 servings of trail mix.
⇒Cup of raisins = [tex]2\frac{1}{4} = \frac{9}{4}[/tex] and number of serving = 4
We have to find the cups of raisins are in each serving
Then by definition of unit rate we have;
[tex]\text{unit rate per serving} = \frac{\frac{9}{4} }{4} = \frac{9}{16}[/tex] cups of raisins
therefore, [tex]\frac{9}{16}[/tex] cups of raisins are in each serving

what is the solution of 7k+2=4k-10?
Use one of the reasons from the box to justify each step.
You may use a reason more than once.
k=-4
7k+2=4K-10
+10 +10
7k+12=4K
-7k -7k
12=-3k
Divide both sides by -3
K=-4
The solution is k = -4.
To solve the linear equation 7k+2=4k-10, we need to isolate the variable k on one side of the equation. Here are the steps to simplify the equation and find the value of k:
Subtract 4k from both sides to eliminate the variable from the right side of the equation: 7k - 4k + 2 = 4k - 4k - 10, which simplifies to 3k + 2 = -10.
Subtract 2 from both sides to eliminate the constant term from the left side of the equation: 3k + 2 - 2 = -10 - 2, which simplifies to 3k = -12.
Divide both sides by 3 to solve for k: 3k / 3 = -12 / 3, which simplifies to k = -4.
Now we need to check the solution by substituting k = -4 back into the original equation to verify that it holds true:
7(-4) + 2 = 4(-4) - 10
-28 + 2 = -16 - 10
-26 = -26
The left and right sides of the equation are equal, confirming that k = -4 is the correct solution. Thus, the steps are justified and the solution is reasonable

Ameena's boat travels 35 miles per hour. The best fishing spot in the lake is 27 miles away from her starting point. If she drives her boat for 2/3 of an hour, will she make it to the best fishing spot on the lake?
Answer: No, she will not make it tot he best fishing spot on the lake.
Step-by-step explanation:
Since we have given that
Distance between the starting point and the best fishing spot = 27 miles
Speed at which Ameena drives = 35 miles per hour
Time she takes to drive her boat is given by
[tex]\frac{2}{3}\text{ of an hour}[/tex]
As we know that ,
[tex]Distance=Speed\times time\\\\Distance=35\times \frac{2}{3}\\\\Distance=\frac{70}{3}\\\\Distance=23.33\text{ miles}[/tex]
But we have given that the best fishing spot in the lake is 27 miles away from her starting point ,
[tex]\text{And with this speed in }\frac{2}{3}\text{ of an hour he reached only }23.33 \text{ miles. }[/tex]
So,
No, she will not make it tot he best fishing spot on the lake.
No, she will not
Find how far Ameena's boat will have traveled at two thirds of an hour.
(35 miles per hour) (2/3 of an hour)= 23.33 miles
Ameena's boat will have traveled just over 23 miles. She will not have reached the best fishing spot which will still be approximately another 4 miles away.
To find how far Ameena's boat has traveled you multiplied the speed by the time, but since time is now the unknown variable, divide the distance by the speed
27 miles divided by 35 miles per hour to get 0.77 hours
What is the conversion for hours to minutes?
0.77 = 46.2 minutes
A bus averages 4 miles per hour faster than a motorcycle. If the bus travels 180 miles in the same time it takes the motorcycle to travel 156 miles, then what is the speed of each?
Set up equations:
(1) speedbus = speedbike+4
(2) speedbus/speedbike = 180/156
plug (2) into (1)
speedbike * 180/156 = speedbike + 4
(solve for speedbike)
speedbike = 4 / (180/156-1) = 26 mph
--> speedbus = 26+4 = 30mph
0.1875 rounded to the nearest hundredth
To round the number 0.1875 to the nearest hundredth, you look at the thousandths place. As the digit (5) is 5 or more, we round up, giving us 0.19.
When rounding a decimal number to the nearest hundredth, you need to look at the digit in the thousandth place.
The number 0.1875 has a 5 in the thousandths place.
In rounding, if the digit immediately after the place we're rounding to is 5 or larger, we round up, otherwise we round down. Hence, 0.1875 rounded to the nearest hundredth becomes 0.19.
To clarify, 0.1875 is between 0.18 and 0.19, but is closer to 0.19 because of the 5 in the thousandths place prompting the round up.

Which statement is NOT one of the axioms of Euclidean geometry?
A.
Given any two distinct points, there is exactly one line that contains them.
B.
Every plane contains at least three points that do not lie on the same line.
C.
If two points lie in a plane, the line containing these points also lies in the plane.
D.
If two planes intersect, their intersection is a point.
Answer:
b
Step-by-step explanation:
B: Every plane contains at least three points that do not lie on the same line
To answer this question, we will have to state the 5 axioms of Euclidean geometry and they are;
1. A straight line could be drawn between any two points; This means that as long as there is no obstacle between the two points, then we can say that it is possible to draw a straight line between both points. However, if there is an obstacle between the two points, then it is not possible to draw a straight line.
2. Any straight line that is terminated could still be extended indefinitely; A line segment may be bound by an endpoint, but a straight line is not bounded by any endpoint and as a result, it can be extended indefinitely in both directions.
3. A circle could be drawn with any given center point and any given radius; If for example we use a line segment bounded by two end points. If we use one of these 2 endpoints to be the centre of a circle and make the radius of the circle to be equal to the length of the line segment earlier used as an example, it means if we draw a circle, it will have a diameter that is twice the length of that same line segment.
4. All right angles are definitely equal; A right angle always has a measurement of 90°. This means that regardless of its' orientation, it will still remain 90°.
5. For any given point that is not on a given line, there will be exactly one line passing through the point that would not meet that same given line; This implies that two lines will be parallel to each other if they intersect a third line with the interior angle between them being 180°.
Looking at the given options in the question, the only one that doesn't correspond to any of these 5 axioms I have stated would be option B.

Aleta went to dinner. the bill was 36. she gave the waiter a 15% tip. what was the total ammount Aleta spend on the food and the tip
To calculate the total amount Aleta spent, including the tip, multiply the bill ($36) by the tip percentage (15%) to get the tip amount ($5.40) and add it to the bill to get the total cost ($41.40).
The question asks us to calculate the total amount Aleta spent on dinner including a 15% tip. To find the tip amount, we multiply the bill by the tip percentage in decimal form. The bill is $36, so we calculate 15% of $36 as follows:
0.15 × $36 = $5.40
The total cost of the meal including the tip is $36 (the original bill) + $5.40 (the tip) = $41.40.
