Answer: square root of 10 - 100 3.162
√63 =√32⋅7=√32⋅√7=3√7.
Thus, the square root of 99 lies somewhere between 9.9 and 10. Choosing an estimate in the middle of this range, we know that sqrt(99) is approximately equal to 9.95, with an error of not more than 0.05.
Step-by-step explanation:
Explanation: √83 is an irrational number. You won't be able to simplify it any further either, since it doesn't have any perfect square factors.

The parallel lines are r and s.
What are Parallel lines?Parallel lines are those lines that are equidistance from each other and never intersect each other.
Given that;
There are 4 lines ae shown in figure.
Now,
Since, There are 4 lines ae shown in figure.

james went out for a long walk . He walked 3 2/5 of the mile. then he sat down to take rest . After that he walked 5/7 of a mile. how far did he walk together
Answer:
Altogether James walked [tex]4\frac{4}{35}[/tex] miles.
Step-by-step explanation:
The question involves mixed fractions. Mixed fractions are first converted into proper fractions and then any operation can be performed on them.
Given
Distance of first walk = [tex]3\frac{2}{5}[/tex] of a mile
Distance of second walk = 5/7
In order to find how much he walked altogether, we have to find the sum of both fractions.
[tex]Total\ distance = 3\frac{2}{5}+\frac{5}{7}\\= \frac{17}{5}+\frac{5}{7}\\=\frac{17*7}{5*7} + \frac{5*5}{7*5}\\=\frac{119}{35} + \frac{25}{35}\\=\frac{119+25}{35}\\=\frac{144}{35}\\=4\frac{4}{35}[/tex]
Hence,
Altogether James walked [tex]4\frac{4}{35}[/tex] miles.

An airplane flying with the wind takes 2 hours to travel a distance of 360 miles.
The return trip takes 3 hours flying against the wind.
What is the speed of the airplane in still air and how fast is the wind blowing?
Answer: still air is 150mph. The wind speed is 30mph.
Step-by-step explanation:
X=speed of the plane, Y=speed of the wind.
360/2hours=180
360/3hours=120
2x=180+120
2x=300
X=150
The airplane in still air is 150mph
Add together
X+y=180
150+y=180
Y=180-150
Y=30mph
The wind speed is 30mph
Exercise 3.29. In a school there are four kindergarten classes, with 21, 24, 17 and 28 students. We choose one of the 90 kindergarten students randomly, and denote the number of students in her class by X. Find the expectation and variance of X.
Answer:
Expected mean = 23.2159
Variance = 15.89
Step-by-step explanation:
Given that :
Number of kindergarten students (X) :
21 + 24 + 17 + 28 = 90
P(X):
21/ 90 = 0.233
24/90 = 0.2667
17/90 = 0.1889
28/90 = 0.3111
X : ____ 21 ____24 _____ 17 ______ 28
P(x) : _ 0.233 _ 0.2667 __ 0.1889 __ 0.3111
E(X) = Σ[(p)*p(x)]
(21 * 0.233) + (24 * 0.2667) + (17 * 0.1889) + (28 * 0.3111) = 23.2159
Var(X) : Σ(x²*p(x)) - E(x)²
x² * p(x) = (21^2 * 0.233) + (24^2 * 0.2667) + (17^2 * 0.1889) + (28^2 * 0.3111) - 23.2159^2
554.8667 - 538.97801281

At a hockey game, a vender sold a combined total of 156 sodas and hot dogs. The number of sodas sold was two times the number of hot dogs sold. Find the number of sodas and the number of hot dogs sold.
Answer: They sold 104 sodas and 52 hotdogs
Step-by-step explanation: If we represent sodas as x and hotdogs as y then x+y=156. There is twice as many sodas as hotdogs so x=2y. We can then substitute x for 2y so the equation would be 2y+y=156 or 3y=156. We divide both by three and get y=52 we plug that back in to the equation x=2y and we get x=104. We then check to make sure it is correct and get 104+52=156 and 104/2=52. Hope this helps.

A mini bus can carry 8 students. How many mini buses will be needed to transport 38 students?
Answer:
5 buses
Step-by-step explanation:
you need to divide the number of students (38) by the number of students a mini bus can carry.
38 : 8 = 4.75
since they want to know how many buses will be needed to transport all students, you round 4.75 to 5

Find the equation of a line that passes through the point (2,-5) and is perpendicular to the y-axis. Do not put any spaces in your answer.
Answer:
y=-5
Step-by-step explanation:
Equation of the line
Lines can be expressed in several forms. The slope-intercept form of the line is:
y = mx + b
Where m is the slope of the line and m is the y-intercept.
If the line is perpendicular to the y-axis, then it's a horizontal line. Horizontal lines have slope m=0, thus, the equation is:
y = b
To find the value of b, just substitute the given point:
-5=b
The equation of the line is:
y=-5
