I will try my best to assist you with your question!
The answer is: C) 3 hours and 12 min
Find the miles per hour the train is going, 75 mph. Then divide 240 by the miles per hour, and you get minutes. Convert minutes into hours
Divide 100 miles by 80 minutes, then multiply by 60 to get how many miles per hour instead of miles per minute
Then divide 240 by 75 and multiply again by 60 to get hours instead of minutes

at 5:00 a.m. , the temperature was -6 degrees Celsius. the temperature steadily increased 2 degrees each hour. what was the temperature at noon
-20 degrees by the time it was noon :)
Answer:
8 degrees Celsius is the answer
Step-by-step explanation:
Since at 5 a.m. the temperature was -6 degrees and the temperature increased 2 degrees every hour until noon, you can subtract noon (12) by 5 to realize that 7 hours have passed. Now multiply 2 by 7 to get 14. This means that the total increase in temperature was 14 degrees Celsius.
Finally, add 14 to -6, and when you do that math, you will get an answer of 8.
Characteristics of Relations
3 relations are shown in the image. Place the characteristics in the correct column.
A relation in mathematics can be reflexive, symmetric, or transitive. To determine which characteristics a relation displays, you'd need to evaluate each pair of elements. This can solidify your understanding of such mathematical concepts.
Explanation:In Mathematics, a relation is a set of ordered pairs (a, b). Different characteristics define each relation. For example, a relation can be reflexive if every element is related to itself, symmetric if for every pair (a, b) in the relation, the pair (b, a) is also in the relation, or transitive if for every set of three elements a, b, and c, if (a, b) and (b, c) are in the relation, then (a, c) must also be in the relation.
To place the characteristics in the correct column, you may need to review each relation's properties in the image and ascertain whether they exhibit reflexivity, symmetry, or transitivity. Don't forget to check every pair of the elements in order to ensure your decision. This exercise can help solidify your understanding of these complex concepts in mathematics.

the equation y=0.5x represents the distance henry hikes, in miles, over time, in hours. the graph represents the rate that clark hikes. determine which hiker is faster. explain.
I think there's supposed to be a picture here. Anyway, you can find out by finding the slope of the line on the graph and comparing it to .5 which is Henry's slope. If the graphed slope is larger than .5 then Clark hikes faster, if it is less than .5, Henry hikes faster.
Hope this helps :)
To determine which hiker is faster, you need to examine the graph of Clark's rate and compare it to the rate of Henry, which is 0.5 miles per hour.
In the equation y = 0.5x, where y represents the distance Henry hikes in miles over time x in hours, the coefficient 0.5 is the rate at which Henry hikes. This means Henry is hiking at a rate of 0.5 miles per hour.
On the other hand, the graph represents the rate at which Clark hikes. To determine who is faster, you need to compare the rate of Clark's hiking to Henry's rate.
If the graph of Clark's rate is represented by a line with a slope greater than 0.5, then Clark is faster. If the slope is less than 0.5, then Henry is faster.
For example, if the graph for Clark's rate is represented by the equation y = 0.6x, then Clark is hiking at a rate of 0.6 miles per hour, which is faster than Henry's rate of 0.5 miles per hour.
So, to determine which hiker is faster, you need to examine the graph of Clark's rate and compare it to the rate of Henry, which is 0.5 miles per hour.

|a|-3/4=-5/8 Solve and show your work?
Answer:
{-1/8, 1/8}
Step-by-step explanation:
Solve |a|-3/4=-5/8 for |a|: Add 3/4 to both sides of this equation, obtaining:
|a| - 6/8 + 6/8 = -5/8 + 6/8, or |a| = 1/8. This absolute value function has two components:
a = 1/8 and a = -1/8.
Sure, I'd be happy to walk you through the solution.
1. The first step is to rewrite the absolute value term in the equation to make it a little easier to work with. We can write |a| as 4|a|/4 to help solve the equation in fractional terms. This makes our equation 4|a| - 3/4 = -5/8.
2. Now, multiply every term by 4 to get rid of the fractions. This result in 4*4|a| - 4*3/4 = 4*-5/8, which simplifies to 4|a| - 3 = -5/2.
3. In order to solve for |a|, we'll need to isolate it on one side of the equation. To do this, add 3 to both sides, which gives 4|a| = -5/2 + 3.
4. Simplify the right side of the equation to get 4|a| = 1/2.
5. From here, divide each side by 4 in order to solve for |a|. This gives us |a| = (1/2) / 4.
6. Simplify |a| to get |a| = 1/8.
7. Now that we found |a| = 1/8, we know that a can be positive or negative because it's the absolute value of a number. Therefore, the solutions to the original equation |a| - 3/4 = -5/8 are a = 1/8 and a = -1/8.
Baking a tray of corn muffins takes 4 cups of milk and 3 cups of wheat flour. Baking a tray of bran muffins takes 2 cups of milk and 3 cups of wheat flour. A baker has 20 cups of milk and 18 cups of wheat flour. He makes $3 profit per tray of corn muffins and $2 profit per tray of bran muffins. How many trays of each type of muffin should the baker make to maximize his profit?
Answer:
2 barn and 4 corn
Step-by-step explanation:
Here we have to pay attention to milk, because both recipes require the same amount of flour, 3 cups, so the flour will be used in equal amounts whatever the recipe we use. Given this, we can only bake 6 trays at most.
Can we bake 6 of barn? YES! Using all our flour and 6*2=12 cups of milk and getting 6 trays of barn muffins. This will give us $2 * 6 = $12. However we keep 8 cups of milk with not use, that could have been used to bake one of corn that are twice as profits as barn. What happens if we replace one of the 6 barn trays by one of corn?
This way we will have 5 of barn and 1 of corn and we will be using 10 + 4 = 14 cups of milk. Our profits will be: $2*5 + $3*1 =$13. This will improve our income!
Lets replace another barn by one of corn. This way we have 4 of barn and 2 of corn: $2*4 + $3*2 = $14. Again, more income!!
Lets replace another and have 3 barn and 3 corn: $2*3 + $3*3 = $15. And we can bake them, as they need 2*3 = 6 cups for barn and 4*3=12 cups of milk for corn.
If we replace another we will have 2 of barn and 4 of corn. Our income will be: $2*2 + $3*4 = $16. This implies using 4 cups of mil for barn and 16 cups of mil for corn. So, we use all of our milk.
Any change in the distribution of barn and corn will, even impossible to bake as there will not be more ingredients or less profit

There are 13 cups of milk in a container. You drink.75 cup of the milk each morning and 2.5 cups of milk each evening. When will you run out of milk?
The total daily consumption of milk is 3.25 cups (0.75 in the morning and 2.5 in the evening) and there are 13 cups of milk total. So if you divide the total milk by daily consumption, which is 13 ÷ 3.25, you get 4. Therefore, you will run out of milk in 4 days.
Explanation:This is a simple math problem that can be solved with division and addition. You are consuming .75 cups of milk every morning and 2.5 cups of milk every evening. Therefore, each day, you are drinking a total of 0.75 + 2.5 = 3.25 cups of milk. There are 13 cups of milk present initially and every day you're consuming 3.25 cups. To find out when will you run out of milk, you simply divide the total amount of milk by the amount of milk drank per day: 13 ÷ 3.25 = 4 days. Therefore, you will run out of milk in 4 days.

To solve these types of problems you need to know the basic rule of pemdas.
(P)arentheses(E)xponents(M)ultiplication(D)ivision(A)ddition(S)ubtractionMultiplication/division and addition/subtraction are in no particular order; they are solved from left to right. Knowing the rule of pemdas, you can then solve these types of problems.
I have attached a picture to hopefully help you see how these problems can be solved. I solved the problems using pemdas step-by-step. Feel free to ask any questions you have in the comments! :)
__________________________________________________________
{Explanation}:(29 - 5) ÷ 2 - 6²
1. Pemdas tells you to solve inside the (p)arentheses first, so solve (29 - 5) then rewrite the expression.
(24) ÷ 2 - 6²
2. After solving inside all of the parentheses, pemdas then tells you to solve for the (e)xponents. Solve where 6 is being carried to the power of 2 and then rewrite the expression.
(24) ÷ 2 - (36)
3. The next step in pemdas is to divide before subtracting, since those are the only two operations left. Divide 24 by 2 and then rewrite your expression.
(12) - (36)
4. The last and only step is to subtract 36 from 12. After doing so you will get your final answer.
[tex]\boxed {-24}[/tex]
__________________________________________________________
(9 - 2)² + (20 ÷ 5)
1. Pemdas tells us to solve inside the parentheses first, so solve inside both of the parentheses and then rewrite the expression.
(7)² + (4)
2. The next step is to solve for the exponents. Solve 7 carried to the power of 2 and then rewrite the expression.
(49) + (4)
3. The last and final step is to add the two terms together, 49 and 4. After doing so you will be left with your final answer.
[tex]\boxed {53}[/tex]
__________________________________________________________
(7 × 6 + 8²) + 2
1. Pemdas tells us to solve inside the parentheses first. There are multiple operations being done inside of the parentheses, so the first operation we will complete is exponents because that is what pemdas tells us to do. Solve 8 carried to the power of 2, then rewrite the expression.
(7 × 6 + 64) + 2
2. Now we can multiply 7 and 6 (because multiplication comes before addition) and then rewrite the expression.
(42 + 64) + 2
3. Solve inside the parentheses by adding 42 and 64. Then rewrite the expression.
(106) + 2
4. The fourth and final step is to add the two terms, 106 and 2, together. Then you will be left with your final answer.

{Answers}:A square is folded in half then folded in half again. What is the fraction of the original shape is the folded side
The squad would be folded into fourths.
Hope it helps ❤️
When a square is folded in half twice, the folded part becomes 1/4 or one-quarter of the original square's area.
Explanation:When a square is folded in half, it becomes a rectangle, reducing its area to half the original square's area. When this rectangle is folded in half again, its area reduces to half of its current state or a quarter of the original square's area. Therefore, the folded part is 1/4 or one-quarter of the original shape.
For example, let's say our original square is 4 cm by 4 cm, therefore the area is 16 cm^2. If it is folded in half, the new shape is 4 cm by 2 cm with an area of 8 cm^2, half of the original square. Fold this rectangle again in half, the new shape is 2 cm by 2 cm with an area of 4 cm^2, which is a quarter of the original square's area.

I'll help with number 5 since number 4 is a bit too small and squished to read.
Check out the attached image below for the full two-column proof. The added entries are in red.
The given statement is basically what the teacher shows at the top of the problem, which is the fact that angle 5 and angle 2 are congruent. You just repeat this statement.
The reason for statement 2 is that angle 2 and angle 4 are vertical angles. They are opposite angles formed by a pair of intersecting lines. This is the vertical angle theorem at work. We'll use the vertical angle theorem again for statement 4 when we say that angle 5 and angle 8 are the same measure.
The transitive property comes into play when we connect angles 2, 5, and 4 together, which helps us get line 3. We also connect angles 4, 5 and 8 together to get the last line, which is why the reason for statement 5 is "transitive property"
