What is work and time in mathematics?
In mathematics, work refers to the amount of effort or energy needed to complete a task or achieve a goal. Work is often measured in units such as joules or calories.
Time refers to the duration or amount of time it takes to complete a task or achieve a goal. Time is often measured in units such as seconds, minutes, hours, or days.
To estimate the time it will take Andrea and her friend to paint the fence together, we can use the formula:
Total Time = (Time for Person 1 x Time for Person 2) / (Time for Person 1 + Time for Person 2)
Using this formula, we can estimate the time it will take Andrea and her friend to paint the fence together as:
Total Time = (6 hours x 4 hours) / (6 hours + 4 hours) = 24/10 = 2.4 hours
Therefore, the best estimate of the time it will take Andrea and her friend to paint the fence together is 2.4 hours.

Answer:
m∠RQS = 47°
Step-by-step explanation:
The collinear points form a "straight angle," one whose measure is 180°. That is the sum of the marked values:
(3x -5) +(x +1) = 180

Find the matrix A representing the reflection about the line L in R^2 which consists of all scalar multiples of the vector [6 3]. A = []
Answers
the matrix A, which is composed of all scalar multiples of the vector [6 3], and represents the reflection about the line L in R2.A = [[-6/7, 9/7],[9/7, 6/7]]
Let L be the line in R^2 which consists of all scalar multiples of the vector [6 3], then the equation of the line is y= (3/6)x.
We need to find the matrix A which represents the reflection about the line L.
Let (x1, y1) be any point on the line L and let (x2, y2) be its reflection about the line L.
Now, we know that the slope of the line L is 3/6, hence the slope of the normal to the line L is -6/3.
So, the equation of the normal to the line L is y = -(6/3)x. Now, we can use the point-slope form of the line equation to calculate the equation of the line passing through (x1, y1) and its reflection (x2, y2).
The line that connects (x1, y1) and (x2, y2) has the following equation:
y-y1 = (y2-y1)/(x2-x1) (x-x1)
=> y-y

Trapezoid and Kites. (picture below)
Answers
69
Step-by-step explanation:
angles 111 and 3 are the same. in a trapezoid bottom base angles are the same and the top base angles are the same. so in order to find angle 2 you must subtract 111 from 180 because the top angles are supplementary to the bottom
180 - 111 = 69
Answer:
The answer will be 69
This is because angle 3 would also be 111
Angles in a quadrilateral add up to 360
So, 360-(111+111)
=138
there are two angles left, angle 1 ND 2, THEY ARE THE SAME VALUE. So DIVIDE 138 by 2, and you would get your answer 69 degrees.
Hope this helps!!

Two turtles come from opposite sides of the road, starting at the same time and moving at the same speed. When they met, they jvere 72 inches from the right hand edge of the road. How wide is the road?
Answers
Answer:
144 inches
Step-by-step explanation:
If they are moving at the same speed and start at the same time, they have to go the same distance
That means they will meet in the middle
If they are 72 inches from the right side that means the middle is 72 inches from the right side
The road is 2 times 72 inches

Sally made a profit of $2500 after selling stocks for $19000 after 2.5 years. What was her average annual percentage gain?
13.25%
6.06%
3.78%
Answers
Sally's average annual percentage gain is approximately 5.26%.
To calculate Sally's average annual percentage gain, we can use the formula:
Average Annual Percentage Gain = (Profit / Initial Investment) * (1 / Time) * 100
Profit = $2500
Initial Investment = $19000
Time = 2.5 years
Substituting the values into the formula:
Average Annual Percentage Gain = (2500 / 19000) * (1 / 2.5) * 100
= (0.1316) * (0.4) * 100
= 5.26
Therefore, Sally's average annual percentage gain is approximately 5.26%.

The three steps below were used to find the value of the expression [(-10 + 2) - 1] + (2 + 3). Step 1: ? Step 2: -9 + 2 + 3 Step 3: -7 + 3 Which expression is missing from Step 1? Question 3 options: [-10 + -1 + 2] + (2 + 3) [-8 - 1] + (2 + 3) [-10 + 1] + (2 + 3) [8 + 1] + (2 + 3)
Answers
Therefore, the missing expression in Step 1 is [-8 - 1] + (2 + 3).
In order to find the missing expression in Step 1, let's analyze the given steps and the final expression.
Step 1: ?
Step 2: -9 + 2 + 3
Step 3: -7 + 3
To find the missing expression in Step 1, we need to work backwards from Step 3 to Step 1.
In Step 3, the expression "-7 + 3" gives us a result of -4.
In Step 2, the expression "-9 + 2 + 3" gives us a result of -4.
So, the missing expression in Step 1 should also evaluate to -4 when performed correctly.
Let's check the available options:
[-10 + -1 + 2] + (2 + 3) = -11 + 2 + 5 = -4
[-8 - 1] + (2 + 3) = -9 + 5 = -4
[-10 + 1] + (2 + 3) = -9 + 5 = -4
[8 + 1] + (2 + 3) = 9 + 5 = 14
Out of the given options, only option 2, [-8 - 1] + (2 + 3), correctly evaluates to -4. Therefore, the missing expression in Step 1 is [-8 - 1] + (2 + 3).

Find the 75th term of the following arithmetic sequence.
12, 21, 30, 39,
Answers
9514 1404 393
Answer:
678
Step-by-step explanation:
The sequence has a first term of 12 and a common difference of 21-12 = 9. The explicit formula for the n-th term is ...
an = a1 +d(n -1)
For a1 = 12 and d = 9, this is ...
an = 12 + 9(n -1)
Using 75 for the value of n, we have ...
a75 = 12 + 9(75 -1) = 12 + 666 = 678
The 75th term is 678.
if 9+x/6=11 then what’s the value of 1+3x??
Answers
Answer:
Step-by-step explanation:
It's hard to tell what you really intend. I'll do it both ways.
Way One
9 + x/6 = 11 Subtract 9 from both sides.
x/6 = 11 - 9
x/6 = 2 Multiply both sides by 6
x = 2 * 6
x = 12
1 + 3x = 1 + 3*12 = 1 + 36 = 37
Way Two
(9 + x)/6 = 11 Multiply both sides by 6
9 + x = 11 * 6 Simplify the right side
9 + x = 66 Subtract 9
x = 57
1 + 3*57 = 1 + 171 = 172
