Answer:
312.7 in^2Step-by-step explanation:
This problem is on the mensuration of flat shapes, sectors and arc.
we know that the area of a sector is given as
A=(∅/360)*πr^2
Given that the length of the wiper R=24 in
and the length of the blade r= 16in
To find the area of the wiped surface we only require the length of the blade as the radius
The area of the wiped surface is given as= (140/360)*3.142*16^2
A= 0.3888*3.142*256
A=312.7 in^2

PLEASE HELP QUICK!!! 3x − 2(6 − x) = 7x + 2(5 + x) − 6
Answer:
it would be x=-4
hope i helped ya
Answer:
x = -4
Step-by-step explanation:
3x -2(6-x) = 7x +2(5+x) -6
Distribute -2 through the parentheses 3x -12 +2x = 7x +2(5+x) -6
Distribute 2 through the parentheses 3x -12 +2x = 7x +10 +2x -6
3x -12 +2x = 7x +10 +2x -6 cancel equal terms on both sides of the equation
3x -12 = 7x +10 -6 subtract the numbers 3x -12 = 7x +4
Move variable to the left left handed side and change its sign
3x -7x-12 = 4 --> 3x -7x = 4 + 12 --> -4x = 4+12 --> -4x = 16
Divide both sides of the equation by -4 --> x = -4

The intersection A n(B n C) is an empty set: {∅}
How to get the intersection between the 3 sets?
For two sets A and B.
A n B is defined as the intersection between A and B, so it is the set of common elements between A and B.
Here we have:
A = {1, 3, 5, 7, 9}B = {2, 4, 6, 8, 10}C = {1, 5, 6, 7, 9}Then:
A n (B n C)
First, we have:
B n C = {6}
6 is the only common element between B and C.
And 6 does not belong to A, then:
A n (B n C) = {∅}
Which is an empty set.

Graph the line with slope 8 and y-intercept −8.
To create the slope 8, you would have to do the rise over run:8/1. which means u go up 8 units and to the side one unit and you keep doing that. And since the y-intercept is -8, then you start your first point at -8 and continue to go up.
The graph is attached below:
What is graph?Graphing basic functions like linear functions and quadratic functions is easy. The basic idea of graphing functions is
Identifying the shape if possible. For example, if it is a linear function of the form f(x) = ax + b, then its graph would be a line; if it is a quadratic function of the form f(x) = ax2 + bx + c, then its a parabola.
finding some points on it, by substituting some random values of x and finding the corresponding values of y by substituting each value into the function.
For graphing quadratic function also, we can find some random points on it. But this may not give a perfect U-shaped curve. This is because, to get a perfect U-shaped curve, we need where the curve is turning. i.e., we have to find its vertex. After finding the vertex, we can find two or three random points on each side of the vertex and they would help in graphing the function.
Given:
slope= 8
y- intercept = -8
So, the equation can be
y= mx+ c
y= 8x - 8

a triangle has side lengths of (9.7m-6.8m) centimeters, (6.6m+6.5p) centimeters, and (2.2p-6.4n)centimeters. which expression represents the perimeter, in centimeters, of a triangle?
Answer:
To find the perimeter of a triangle, you would need first all three side lengths.
9.7m-6.8m = 2.9, 6.6m+6.5p=7.1, 2.2p-6.4= -4.2. once I added all the sides it was 5.8.

7x + 10y = 27
X-10y = -19
The solution is
(Simplify your answer. Type an ordered pair.)
The solution is (1,2)
Step-by-step explanation:
7x + 10y = 27
x - 10y = -19 +--------------------
8x = 8
Divide by 8 on both sides
x = 1
To find y substitute any of the equations to 1
7(1) + 10y = 27
7 + 10y = 27
Substract 7 from both sides
10y = 20
Divide by 10
y = 2
A car driving at 50 miles per hour drives 2 hours. What distance did it cover?
Answer: It travels 100 miles
Step-by-step explanation:
If it drives 50 miles an hour it would drive 100 miles an hour if it were driving for 2 hours.
Based on the speed of the car and the amount of time it was travelling, the car travelled 100 miles in 2 hours.
The distance that the car travelled can be calculated by:
Distance = Speed x Time
Speed = 50 miles per hour
Time = 2 hours
Distance = 50 x 2
= 100 miles
In conclusion, the car would have gone 100 miles.

Step-by-step explanation:
A relation is a mapping from a set of input values, called the domain, to a set of output values, called the range. In a relation, each element in the domain can be assigned to one or more elements in the range.
A function is a relation where each input value is assigned to exactly one output value.
The domain of a function is the set of all input values, or x-values, for which the function is defined.

By how much does the outlier in the following data set increase the range of the data set?
{59, 70, 63, 46, 60, 38, 60, 51, 48, 85, 66, 55, 236}
To find the range, subtract the smallest from the biggest number.
The outlier is most commonly the biggest or smallest number. Obviously it is 236 in this situation.
To find how much the outlier increases the range, you need to find out the range WITH and WITHOUT the outlier.
Without the outlier: 39
With the outlier: 190
Then you subtract 190 - 39 because you are trying to find out how much MORE RANGE the outlier makes.
The answer is 151.
THEREFORE, The outlier increases the range by 151.

∠CAT and ∠TAD is a linear pair. If m∠CAT = 14 and m∠TAD = x+10, find x.
(show work please)
Answer:
156
Step-by-step explanation:
Since, ∠CAT and ∠TAD is a linear pair.
Therefore,
∠CAT + ∠TAD = 180°
14° + (x + 10)° = 180°
(x + 24)° = 180°
x + 24 = 180
x = 180 - 24
x = 156
