A fast bi-level train travels from Washington, D.C. to Perryville Maryland. If this train traveled 75 miles in about .75 hours, what was the speed of the train
Answer:100 mph
Step-by-step explanation: it’s always distance divided by time. lol
The train travels to a distance of 75 miles in 0.75 hours, then the speed of the train will be equal to 100 miles per hour.
What are arithmetic Operations?The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.
Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.
As per the data mentioned in the question,
Distance (d) traveled by train = 75 miles
Time (t) taken by train to travel the distance = 0.75 hours
Then, use the equation of speed (s),
[tex]Speed =\frac{Distance}{Time}[/tex]
s = 75/0.75
s = 100 miles per hour.

Given is a scatterplot.
A scatterplot is positive if an increase or decrease in one of the quantity results in the corresponding increase or decrease in the other quantity.
If it is opposite, then the relation is negative.
Here, when the x value increases, y value is also increasing.
So the relationship is positive.
A scatterplot show a linear relationship, if the values are closely resembling in a line.

In a mixture of raisins and peanuts, 30% of the mixture is raisins and there 56 peanuts; how many raisins are in the mixture?
Answer: 24 raisins
Step-by-step explanation:
30% of the mixture are raisins which means that 70% are peanuts.
That 70% translates to 56 peanuts.
The total of the mixture is therefore:
= 56 / 70%
= 80 mixture of raisins and peanuts
Raisins are 30%:
= 30% * 80
= 24 raisins

PLEASE HELP quickkkk
Answer: see below
Step-by-step explanation:
Just apply Proportionality Theorem at correct time, with correct proportions, It tells, the ratio of two corresponding arms always equal.
So, 1) AB/BC = AJ/JI
2.5/2.25 = AJ/1.8
AJ = 2.5* 1.8 / 2.25
AJ = 2
2) BC/CD = JI / IH
2.25/CD = 1.8/1.2
CD = 2.25 * 1.2 / 1.8
CD = 1.5
3) CD/DE = IH/HG
1.5/3.5 = 1.2 / HG
HG = 1.2 * 3.5 / 1.5
HG = 2.8
4) For GF, we should use "Pythagoras Theorem"
h² = a² + b²
GF² = 6.5² - 6²
GF² = 42.25 - 36
GF = √6.25
GF = 2.5
5) Perimeter = 2.5 + 2.25 + 1.5 + 3.5 + 6.5 + 2.5 + 2.8 + 1.2 + 1.8 + 2
P = 26.55
6) Area = 1/2 * b * h
A = 1/2 * 9.65 * 10.3
A = 49.70

Isabel has just started a photo-sharing website and she is preparing for a presentation for an investor. Her site has 150 users and is growing by 25 users per day. Her competitor's site has 600 users and is growing by 10 users per day.
Answer: See Explanation
Step-by-step explanation:
Your question isn't well analysed but I guess that you want to calculate when both of them will have same number of users.
Let the number of days that both of them will have thesame number of competitors be x.
Therefore,
150 + 25x = 600 + 10x
25x - 10x = 600 - 150
15x = 450
x = 450/15
x = 30
They'll have same competitors by the 30th day.
The number of competitors will be:
= 150 + 25x
= 150 + 25(30)
= 150 + 750
= 900

find 21.4 of 855 percent equation
Answer:
21.4% of 855=182.97
Step-by-step explanation:
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 855 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 855 is 100%, so we can write it down as 855=100%.
4. We know, that x is 21.4% of the output value, so we can write it down as x=21.4%.
5. Now we have two simple equations:
1) 855=100%
2) x=21.4%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
855/x=100%/21.4%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 21.4% of 855
855/x=100/21.4
(855/x)*x=(100/21.4)*x - we multiply both sides of the equation by x
855=4.67289719626*x - we divide both sides of the equation by (4.67289719626) to get x
855/4.67289719626=x
182.97=x
x=182.97
now we have:
21.4% of 855=182.97

Step-by-step explanation:
We know to find the area of a rectangle we need to multiply the length times the height.
In other words,
[tex]a = l \times w[/tex]
We know our length is 75 and our height is 55, so lets multiply it.
[tex]75 \times 55 = 4125[/tex]

PLS HELP AND SHOW CHECK AND WORK ME AND MY FRIEND NEED HELP
Answer:
1) k = -10
2) n = -4
3) a = -9
Step-by-step explanation:
1) -4 = 6 + k
*we want to get k alone, so we will subtract 6 from both sides*
-4 = 6 + k
-6 -6
-10 = k
*in order to check this, we will plug the value we found for k, -10, into the original equation*
-4 = 6 + k
-4 = 6 + (-10)
-4 = -4
*this is correct because -4 = -4, so that is how we check*
2) -4n = 16
*we want n alone, we must divide by -4 on both sides*
-4n = 16
n = -4
*in order to check this, we plug what we found for n, -4, into the original equation*
-4n = 16
-4(-4) = 16
*a negative multiplied by a negative is a positive!*
16 = 16
*this is correct because 16 = 16*
3) 3/4a = -12
*we want a alone, so we will multiply by the negative reciprocal to get rid of the fraction on the left side*
a = -12 times 3/4
a = -9
*in order to check this, we will plug what we found for a, 9, into the original equation*
3/4a = -12
3/4 (-9) = -12
-12 = -12
*this is correct because -12 = -12*
