The ratio of emails sent to emails received by Nick that month is 5:3 in its simplest form, determined by calculating their greatest common divisor.
Explanation:The subject of your question is ratios and it falls under the category of Mathematics.
'For every 50 emails that Nick sent in a month, he received 30 emails.' This tells us about a ratio. A ratio is a way to compare amounts of something.
The ratio in this case is the number of emails sent by Nick to the number of emails he received. We express this ratio as '50:30'.
To simplify the ratio, we find the greatest common divisor (GCD) of 50 and 30, which is 10. So, we divide both numbers by 10. Thus, our simplified ratio is 5:3.
This means Nick sent 5 emails for every 3 emails he received, in simplest terms.

identify the coordinates of four points on the line with given slope is 0.2 and y-intercept is 0.3
Final answer:
The four points on the line with a slope of 0.2 and y-intercept of 0.3 are (0, 0.3), (1, 0.5), (2, 0.7), and (3, 0.9).
Explanation:
The equation of the line can be written in the form y = mx + b, where m is the slope and b is the y-intercept. In this case, the slope is 0.2 and the y-intercept is 0.3. To find four points on the line, we can choose any x-values and substitute them into the equation to find the corresponding y-values.
For example, let's choose x = 0, 1, 2, and 3:
When x = 0, y = 0.3
When x = 1, y = 0.5
When x = 2, y = 0.7
When x = 3, y = 0.9
So, the four points on the line with a slope of 0.2 and y-intercept of 0.3 are (0, 0.3), (1, 0.5), (2, 0.7), and (3, 0.9).

It takes an express train 30 minutes to travel 45 miles at that same rate of speed how many miles does the train travel in 12 minutes
Well if you divide 30 by 10 then multiply by 4 you get 12 minutes.
Do the same for 45,
45 divided by 10 = 4.5 then multiply by 4 = 18
The number of miles the train will travel at the same speed is 18 miles
From the question,
We are to determine the number of miles the train travel in 12 minutes
From the question
It takes an express train 30 minutes to travel 45 miles
First, we will determine the speed
From the formula
[tex]Speed = \frac{Distance}{Time}[/tex]
Distance = 45 miles
Time = 30 minutes
∴ [tex]Speed = \frac{45}{30}[/tex]
Speed = 1.5 miles/mins
Now,
For the number of miles the train travel in 12 minutes
Time = 12 minutes
Using the formula
Distance = Speed × Time
∴ Distance = 1.5 × 12
Distance = 18 miles
Hence, the number of miles the train will travel at the same speed is 18 miles

Question 3 Unsaved Solve for x, given the equation Square root of x minus 5 + 7 = 11
[tex]Domain:\\\\x-5\geq0\to x\geq5\\\\\sqrt{x-5}+7=11\ \ \ \ \ |-7\\\\\sqrt{x-5}=4\ \ \ \ \ |^2\\\\(\sqrt{x-5})^2=4^2\to x-5=16\ \ \ \ \ |+5\\\\\boxed{x=21}\in D\\\\[/tex]
We have the following equation:
[tex]\sqrt{x-5} +7=11[/tex]
To solve this, we first need to subtract the 7 on both sides of the equation.
[tex]\sqrt{x-5} +7-7=11-7[/tex]
The equation then becomes:
[tex]\sqrt{x-5} =4[/tex]
Now we must square both sides of the equation to get rid of the radical/square root symbol.
[tex](\sqrt{x-5})^2 =(4)^2[/tex]
Now we have a normal one step equation.
[tex]x-5=16[/tex]
Add 5 on both sides to find x.
[tex]x-5+5=16+5[/tex]
x=21
To see if this solution is true, we must substitute 21 back into the original equation.
[tex]\sqrt{21-5} +7=11[/tex]
[tex]\sqrt{16} +7=11[/tex]
[tex]4+7=11[/tex]
11=11
Therefore, the solution is true.

Friday: 1,267-38=1,229
So therefore it is 1,229
Answer: It ended at 1229 on Friday.
Step-by-step explanation:
Given : During one week, the stock market did the following: Monday rose 18 points, Tuesday rose 31 points, Wednesday dropped 5 points, Thursday rose 27 points and Friday dropped 38 points.
In integers , we use (+) for rise in quantity and (-) for drop in quantity.
If it started out at 1196 on Monday, then
On Friday = 1196 +18 +31-5+27-38 = 1229 [we use (+) for rise in quantity and (-) for drop ]
Hence, it ended at 1229 on Friday.

Find the equation of the line that is perpendicular to y=-1/5x-3 and contains the point (1,2).
The equation of line will be;
⇒ y = 5x - 3
What is Equation of line?
The equation of line passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;
y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The perpendicular line is,
y = -1/5x - 3
And, The point contain by the line = (1 , 2)
Now,
We need to find the slope of line.
Since, Product of slopes of perpendicular lines are - 1.
So, we find the slope of perpendicular line as;
y = -1/5x - 3
dy/dx = -1/5
So, The slope of the line = - (1/-1/5) = 5
Hence, The equation of line passing through the points (1, 2) and with slope 5 is defined as;
y - y₁ = m (x - x₁)
y - 2 = 5 (x - 1)
y - 2 = 5x - 5
y = 5x - 5 + 2
y = 5x - 3
Thus, The equation of line will be;
⇒ y = 5x - 3

An elevator ascends at a rate of 29.6 feet per second. If a building is 1,450 feet tall, about how long would it take for the elevator to travel from the ground floor to the roof
Answer:
49 seconds.
Step-by-step explanation:
We have been given that an elevator ascends at a rate of 29.6 feet per second. A building is 1,450 feet tall. We are asked to find the time it will take for the elevator to travel from the ground floor to the roof.
To find the time taken by elevator to reach the top of the building, we will use rate formula.
[tex]\text{Time}=\frac{\text{Distance}}{\text{Rate}}[/tex]
[tex]\text{Time}=\frac{\text{1450 ft}}{\frac{\text{29.6 feet}}{\text{second}}}[/tex]
[tex]\text{Time}=\frac{\text{1450 ft}}{\text{29.6 feet}}\times\text{second}[/tex]
[tex]\text{Time}=48.986486\times\text{second}[/tex]
[tex]\text{Time}\approx 49\text{ seconds}[/tex]
Therefore, it will take approximately 49 seconds for the elevator to travel from the ground floor to the roof.
What term is used to describe the difference between limited resources and wants and needs? A. scarcity B. economics C. opportunity cost
a. scarcity
hope this helps! :3
Buehlermaci,
The answer is option A "scarcity." It's not option B because economics is the distribution or a production of a item. It's not option C because opportunity cost is when you are looking at the value of two things before you make a decision on which you want kinda like pros and cons. Scarcity is the shortage on a resource but the person decides to spend it on wants and needs so basically the difference between limited resources and wants and needs.

is -1/3 - 4/5 positive, negative,or zero
It's not zero. Zero can only be produced in adding or subtracting when two equal numbers with opposite signs are added or subtracted. -4 + 4 would give 0. Really tricky things like - 5 - (- 5) would be 0 because the 2 minus signs would give a plus.
-5 + 5 = 0
It's not positive either. Think money. If you owe someone 5 dollars and you put another 6 dollars on a credit card, your net worth isn't going up into the positive. It going down further into the negative. You wouldn't be alone. The US government does this every day. -5 - 6 = - 11
So - 1/3 - 4/5 is negative.

what is the solution of systems of equations 2x -y=7 y=2x+3
Answer:
This system has no solution.
Step-by-step explanation:
The equation y=2x+3 has already been solved for y, so we can substitute (2x+3) for y in the other equation, 2x - y = 7: 2x - (2x + 3) = 7. But note that simplifying this last result turns out -3 = 7, which is of course impossible. Thus, this equation has no solution.
