2.1 Solve : x2-12 = 0
Add 12 to both sides of the equation :
x2 = 12
When two things are equal, their square roots are equal. Taking the square root of the two sides of the equation we get:
x = ± √ 12
Can √ 12 be simplified ?
Yes! The prime factorization of 12 is
2•2•3
To be able to remove something from under the radical, there have to be 2 instances of it (because we are taking a square i.e. second root).
√ 12 = √ 2•2•3 =
± 2 • √ 3
The equation has two real solutions
These solutions are x = 2 • ± √3 = ± 3.4641 /This is the answer

What is angle MNT? Help
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.
Have a great day!
OMG I NEED HELP!!!!!
Answer:
6
Step-by-step explanation:
9/3=3, so if you divide 18/3, you get 6.
Hope this helps you out!! Have a wonderful day :3
Answer:
6
Step-by-step explanation:
This type of problem is a lot easier when you break it down a bit.
First, we know that 9:18 is equal to 1:2 (this is just simplifying by dividing by 9)
So, what's 2*3? 6
Alternatively, you can reason that 9/3 = 3 and 18/3=6

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.
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.

Of the students in Jill's grade, 41 students have a pet and the other 7 students do not. What is the ratio of the number of students who do not have a pet to the total number of students?
Answer:
The answer is 7 : 48.
Step-by-step explanation:
First, you can to calculate how many students are there in Jill's grade by adding the number of students who have pet with the students without pets :
total = 41 + 7 = 48
Next, you have to find the ratio of students without pets to total students :
7 : 48
Answer:
SoluTion :-Total student = Student who have pet + Student who don't have pet
Total Student = 41 + 7
Total Student = 48

In a standard Normal distribution, what percentage of observations lie between z = 0.37 and z = 1.65?
Find the z-table here.
30.62%
40.52%
59.48%
69.38%
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 map has a scale of 2 inches : 25 miles. Gabriel uses the map to find the
distance from the zoo to his house. The distance on the map is 5 inches. If
Gabriel bikes at a rate of 12.5 miles per hour, how long will it take him to get to
the zoo?
2 hours. It's extremely simple this is elementary grade, he needs to travel 25 miles and he's going 12.5 miles an hour, 12.5 x 2 = 25 So in 2 hours he reaches his destination.
The time it will take will be 5 hours.
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
