You have the hypotenuse: 13
You seek the adjacent side: x
You have the angle enclosing the 2: 47 degrees.
The relationship is the Cosine
Solution
Cos(47) = opposite / hypotenuse
Cos(47) = 0.6820 From your calculator
Cos(47) = x / 13 Multiply both sides by 13
13*cos(47) = x
x=8.866

Find an equation of the line through (2,6) and parallel to y=2x+3
Answers
Step-by-step explanation:
We first Find the Slope of the line y=2x+3
The Slope Intercept Form of the equation of a given line is:
y=mx+c
where m is the Slope of that line, and c is the Y intercept.
For this line, the Slope is 2
So the Slope of the line PARALLEL to y=2x+3 will also be 2. And we are given that it passes through the point (2,6)
The Point-Slope form of the Equation of a Straight Line is:
(y−k)=m⋅(x−h)
m is the Slope of the Line
(h,k) are the co-ordinates of any point on that Line.
Here, we have been given the coordinates (h,k) of 1 point on that line as (2,6)
And the Slope m is 2
Substituting the values of h,k and m in the Point-Slope form, we get
(y−2)=(2)⋅(x−6)
(y−2)=2⋅(x-6)
y−2=2x -12
y=2x -12 +2
y=2x-10
The graph will look like
graph{y=2x -10 10 [10, -10, 5, - 5]}

Mr. Singh needed to understand the trend of his students’ latest test scores. Find the mean and median for each set of data, and then determine which gives a better picture of the scores.
Scores: 89, 99, 80, 5, 90, 0, 100, 95
Answers
Answer:
See explanations below
Step-by-step explanation:
Mean is the average of the data
Mean = sum of data/sample size
Sum of data = 89+99+80+5+90+0+100+95
Sum of data = 558
Sample size = 8
Mean = 558/8
Mean = 69.75
Median is the data value in the middle after rearrangement
Rearrange
0 , 5, 80) 89, 90, (95, 99 100
Median = 89+90/2
Median = 89.5
The parameter that gives a better picture of the scores is the Mean since all the given datas are taken into consideration
The mean test score is
✔ 69.75
.
The median test score is
✔ 89.5

A bag contains three different balls, one red (r), one blue(b), one white(w). TWO balls are drawn from the bag without replacement one after the other (at random without looking) and the colors recorded. This means once the first color is drawn, the first ball is kept out of the bag and only 2 colors remain when the second ball is drawn. List the sample space. [Use lower case letters for the colors, preserve the given order, commas separating pairs, no spaces.]
Answers
Answer:
The total sample list is 6
Step-by-step explanation:
The bag has following balls
Red - 1
Blue -1
White -1
Two balls are drawn from the bag without replacing the other -
The probability of drawing 1st ball of any color - 1/3
The probability of drawing 2nd ball of any color - 1/2
These two events are independent of each other
Hence, the probability of deriving two balls without replacement is 1/3*1/2 = 1/6
Hence, the total sample list is 6
The sample space is the list of possible outcomes of an experiment
The sample space is {rb, rw, br, bw, wr, wb}
The color of the three balls is represented as:
Red = r
Blue = b
White = w
Given that the selection is without replacement, the sample space would be:
rb, rw, br, bw, wr, wb
The count of the sample space represents the sample size.
Hence, the sample size of the experiment is 6, and the sample space is {rb, rw, br, bw, wr, wb}

Ben needs to replace two sides of his fence. One side is meters long, and the other is meters long. How much fence does Ben need to buy?
Answers
Answer:
696 39/100 meters
Step-by-step explanation:
Ben needs to replace two sides of his fence. One side is 367 9/100 meters long, and the other is 329 3/10 meters long. How much fence does Ben need to buy?
Side A = 367 9/100 meters
Side B = 329 3/10 meters
How much fence does Ben need to buy?
Total fence Ben needs to buy = Side A + side B
= 367 9/100 + 329 3/10
= 36709/100 + 3293/10
= (36709+32930) / 100
= 69639/100
= 696 39/100 meters
Ben needs to buy 696 39/100 meters

On May 1, you sign a $1000 note with simple interest of 8.5% and a maturity date of December 19. You make partial
payments of $475 on June 2 and $200 on November 4. How much will you owe on the date of maturity?
A) $355.79
B) $354.39
C) $359.53
D) $358.96
Answers
Answer:
The amount to be repaid is $379.26.
Step-by-step explanation:
Period of note from May 1 to December 19 = 233 days
Amount of note or principal = $1,000
Simple interest rate = 8.5%
Maturity date = December 19
Repayments:
June 2 = $475
Nov. 4 = $200
Total paid $675
Simple interest = $54.26 ($1,000 * 8.5% * 233/365)
Total amount to be repaid = $1,054.26
Total amount repaid = 675.00
Balance to be paid on maturity $379.26

40383
so that is your answer “40383”
lol sorry that this was so long
Answer:
The answer is 40,383
Step-by-step explanation:
First, you set up the multiplication. 641 is the largest number so it goes on top. 63 is the smallest number so it goes on the bottom. Draw your line. Next, you multiply 3 by 1 which is 3. Then you multiply 3 by 4 and you get 12. Since this is a two digit number, the 2 goes below the line and the 1 you place on top of the 6. Next, you multiply 3 by 6 and get 18, but don't forget the 1 you placed on top! So you get 19. Then you cross out the 1 on top of the 6 and cross out the 3. After you cross out the numbers you add a 0 under the 3 with the number that is under the line. Then you start multiplying 6x1 which is 6. 6x4 which is 24, place the 4 under the line and bring the 2 on top of the 6. Then multiply 6x6 which is 36, add the 2 you brought on top which is 38. After you did all that work, add all the numbers and your answer is 40,383! Hope this made sense and hope it helps! :3
