describe how do you know if two lines are parallel if all you knew were the equations of the two lines
Answers
Answer:
Step-by-step explanation:
Put what you are given in the form of
y = mx + b
If both equations have the same m, the lines are parallel. For example
y = 4x + 10
y = 4x + 20
These two lines are parallel.
However
y = 8x + 40
y = 4x + 10 are not parallel even though it looks like m could be made the same by taking out 4 in each. Check them out on the graph below.

What is angle MNT? Help
Answers
Answer: acute
Step-by-step explanation: it is less than 90 degrees so it is less the right angle
120 degrees.
Angle MNT is equal to its opposite angle, (I cant tell you the angle as one of the points is not showing, it uses T and Q)
Remember, all triangles have angles that when added together, equal 180 degrees.
So, add 35 and 25, which is 60.
Now subtract 60 from 180, 120.

What is ratio?"The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity. Ratios can be classified into two types. One is part to part ratio and the other is part to whole ratio. The part-to-part ratio denotes how two distinct entities or groups are related. For example, the ratio of boys to girls in a class is 12: 15, whereas, the part-to-whole ratio denotes the relationship between a specific group to a whole. For example, out of every 10 people, 5 of them like to read books. Therefore, the part to the whole ratio is 5: 10, which means every 5 people from 10 people like to read books."
The speed of the bike = 12.5 miles/hour
So, the distance will be = [tex]25/2 * 5 = 125/2[/tex]
Time taken = [tex]125/2 * 1/12.5[/tex]
= 5 hours
Hence, the time taken to get to the zoo = 5 hours

Answer:
c
Step-by-step explanation:
The solution is, The percent is 4.9471%
What is percentage?A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.
given that,
Here, we want to find the percentage of observations that lie above
z = 1.65
Firstly we find the probability of x < z = 1.65
Hence P ( x > 1.65)
This is obtainable from the standard normal distribution table
The value of P(x > 1.65) = 0.049471
This represents a percentage of 4.9471%
Hence, The solution is, The percent is 4.9471%

A coffee table is shaped like a square and has an area of 22 square feet. Find the length of the side of the table to the nearest tenth of a foot.
Answers
Answer:
4.69 feet
Step-by-step explanation:
If the table is a square, all the sides are equal and the area is the length of one side squared. A=l^2
The length must then be the square root of the area. The square root of 22 square feet is 4.6904 feet. Rounded to the nearest tenth, that is 4.69 feet.
