Find the other endpoint of the line segment with the given endpoint and midpoint. Endpoint: (5,-1) Midpoint: (5,-4)
The formula for calculating the midpoint of a line segment is given below
[tex](x,y)=\frac{(x_1+x_2)}{2},\frac{(y_1+y_2)}{2}[/tex]Where the values are
[tex]\begin{gathered} x=5,y=-4 \\ x_1=5,y_1=-1 \end{gathered}[/tex]By substituting the values, we will have
[tex]\begin{gathered} (x,y)=\frac{(x_1+x_2)}{2},\frac{(y_1+y_2)}{2} \\ (5,-4)=\frac{(5_{}+x_2)}{2},\frac{(-1_{}+y_2)}{2} \end{gathered}[/tex]By comparing coefficient, we will have
[tex]\begin{gathered} \frac{(5_{}+x_2)}{2}=5 \\ \frac{(-1_{}+y_2)}{2}=-4 \end{gathered}[/tex]Cross multiply to get the values of x2
[tex]\begin{gathered} \frac{(5_{}+x_2)}{2}=5 \\ 5+x_2=10 \\ \text{substract 5 from both sides} \\ 5-5+x_2=10-5 \\ x_2=5 \end{gathered}[/tex]Cross multiply to get the values of y2
[tex]\begin{gathered} \frac{(-1_{}+y_2)}{2}=-4 \\ -1+y_2=-8 \\ \text{add 1 to both sides} \\ -1+1+y_2=-8+1_{} \\ y_2=-7 \end{gathered}[/tex]Hence,
The coordinate of the other endpoint is ( 5, -7 )
The perimeter of a
rectangular park is 640 yards.
The length of the rectangle is 40
yards less than twice the width.
What are the dimensions of the
park?
The dimensions of the rectangular park are 200 yards by 120 yards.
We have a park. The shape of the park is a rectangle. The perimeter of the rectangular park is 640 yards. We know that the length of the rectangle is 40 yards, less than twice its width. We need to find the dimensions of the rectangular park.
Let the perimeter, length, and width of the rectangle be represented by the variables "P", "l", and "b", respectively. The perimeter of the rectangle is twice the sum of its length and width.
l = 2b - 40
P = 2*(l + b)
640 = 2(2b - 40 + b)
320 = 3b - 40
3b = 360
b = 120
Hence, the width of the rectangular park is 120 yards. We will substitute this value in the above equation to find the length.
l = 2b - 40
l = 2(120) - 40
l = 240 - 40
l = 200
Hence, the length of the rectangular park is 200 yards.

When -2 is multiplied by (-6) the result is 12
What is multiplication?One of the four fundamental mathematical operations, along with addition, subtraction, and division, is multiplication.
Multiply in mathematics refers to the continual addition of sets of identical size.
When negative signs multiply each other the result is a positive sign also when positive signs multiply each other the result is a positive sign
However, when the signs are not same the result is always negative
In the given problem, the signs are same like negative 2 and negative 6
hence the result is a positive sign
and the quantity 2 multiply the quantity 6 gives 12

$14,929 is invested, part at 9% and the rest at 6%. If the interest earned from the amount invested at 9% exceeds the interest earned from the amount invested at 6% by $1139.91, how much is invested at each rate? Round to two decimal places if necessary
Let x be the amount invested at 9% and y the amount invested at 6%.
Then we have:
I) x + y = $14,929
II) 0.09x - 0.06y = $1,139.91
First, we multiply equation II by 100:
9x - 6y = $113,991
Now, we add to it 6 times equation I:
15x = $203,565
x = $13,571
Now, we replace x in equation I to find y:
$13,571 + y = 14,929
y = $1,358
Use the table below to determine whether the argument is valid. TableI start to fall asleep if I read a math book. I drink soda whenever I start to fall asleep. If I drink a soda, then I must eat a candy bar. Therefore, if I read a math book, then I eat a candy bar.The argument is _____________
Okay, here we have this:
Considering the provided information, we obtain the following:
I read a math book. (p)
I start to fall asleep (q)
I drink soda (r)
I must eat a candy bar. (s)
Therefore:
I start to fall asleep if I read a math book. This can be rewritten as: "if I read a math book then I start to fall asleep". And this is p⇒q.
I drink soda whenever I start to fall asleep. This can be rewritten as:"if I start to fall asleep then I drink soda" . And this is q⇒r.
If I drink a soda, then I must eat a candy bar. And this is r⇒s
Now, we need to check: "If I read a math book, then I eat a candy bar.". That is p⇒s.
So, according with the table this argument satisfy the Transitive Reasoning, so this means that the argument is valid.

Here we need to find the missing number when the range is 3.
Let us consider x and y be the missing number.
We know that, the range is difference of smallest and largest number,
So, we can write it as,
x - y = 3
Now, we know that the median is the middle value
Then it can be written as,
y, 4, x
The smallest possible values of y is 1, 2, and 3
Similarly, the possible values of x is 5, 6, 7

Answer:
$400
Step-by-step explanation:
For the first 12 months, he saved
3200/12
= $266.7 each month
In another 12 months,
= $3,200 + x = $8000
(Use x as the unknown total money)
= 8000 - 3200
= 4,800
So, in another 12 months, his total savings will be $4,800
For each month,
= 4,800/12
= $400

Aliyah left the airport and traveled home at an average speed of 40 km/h.
Shanice left at the same time and traveled in the opposite direction with an
average speed of 60 km/h. How long does Shanice need to travel before they are
300 km apart?
Answer:
3 hoursStep-by-step explanation:
When moving in opposite directions from the same point the speeds add up.
Total speed:
60 + 40 = 100 km/h
Distance is 300 km, find the time.
time = distance / speedt = 300/100t = 3 hoursAnswer:
Time = 3 hours
Step-by-step explanation:
The total speed is,
→ 40 km/h + 60 km/h
→ 100 km/h
Formula we use,
→ v = d/t
Then the time taken will be,
→ v = d/t
→ 100 = 300/t
→ 100 × t = 300
→ t = 300/100
→ [ t = 3 ]
Hence, answer is 3 hours.
