Answers

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.

PLS HELP AND SHOW CHECK AND WORK ME AND MY FRIEND NEED HELP

Answers

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*

What is Scatterplots?

Scatterplots are the plotting of set of points on a vertical axis and an horizontal axis. The shows the correlation extent between the numbers of the observed quantities.

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.

Here the points are closely resembling on a line.

So it is linear.

Hence the relationship is positive linear relationship.

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.

Answers

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

Answers

Okay, if the jeans were originally $80, take 40% off of that (40% of 80 is 32) so you’d get 48. Now take 48 and multiply by 1.07 (to get 107% of the $48, to find a percentage you can move the decimal place left 2 digits and multiply), so Justin would pay $51.36 in total.
