It has an infinite amount of solutions.
Explanation:
d-3 = -3+d which can be arranged as: d-3=d-3
Since they are equal to each other, no matter what number you input, your solution will be the same which means that there are an infinite amount of solutions. Let’s put this to the test and put in 5 for d. 5-3=5-3 is 2=2. They are equal to each other which means: infinite solution.
Answer:
The slope of the new road is 0.
Step-by-step explanation:
- the slope of d street line is tan(90)
[if the angle made by a line with x axis is
then, the slope of that line will be tan(
) ]
- here, the angle made by the d street line with x axis is 90 degrees.
- if a road is to be built which is perpendicular to d street , it should make 0 degrees i.e, it should be parallel to x axis .
- so, the slope of new road will be tan(0) = 0
Answer:
20.39
Step-by-step explanation:
35.99 – 15.6 = 20.39
Answer: b. 30%
Step-by-step explanation:
- A measure of relative variability is known as coefficient of variation. It is the ratio of the standard deviation to the mean.
i.e. 
Given: mean = 
Variance = 

Now, 
in percent , 
Hence, correct option is b. 30%.
Answer: 1,900
Step-by-step explanation:
You would round up to 1,900 because in the tens place is a 6 and when you have a number greater than or equal to 5 you round up. Hope this helps!
