Parallelogram LMNO has the coordinates L(1, 4), M(7, 4), N(6, 0) and O(0, 0). The diagonals of Parallelogram LMNO intersect at point P. What are the coordinates of point P?
Answer:
[tex]P(x,y) = (\frac{7}{2},2)[/tex]
Step-by-step explanation:
Given
Parallelogram LMNO
[tex]L = (1,4)[/tex]
[tex]M = (7,4)[/tex]
[tex]N = (6,0)[/tex]
[tex]O = (0,0)[/tex]
Required
Determine the point of intersection
The point of intersection of the diagonal is the midpoint of the parallelogram.
The diagonals are: LN and MO
Calculating midpoint, P of LN
[tex]P(x,y) = (\frac{x_1 + x_2}{2},\frac{y_1 + y_2}{2})[/tex]
Where
[tex]L = (1,4)[/tex] --- [tex](x_1,y_1)[/tex]
[tex]N = (6,0)[/tex] --- [tex](x_2,y_2)[/tex]
So:
[tex]P(x,y) = (\frac{1 + 6}{2},\frac{0 + 4}{2})[/tex]
[tex]P(x,y) = (\frac{7}{2},\frac{4}{2})[/tex]
[tex]P(x,y) = (\frac{7}{2},2)[/tex]
To confirm, we make use of diagonals MO
[tex]M = (7,4)[/tex] --- [tex](x_1,y_1)[/tex]
[tex]O = (0,0)[/tex] --- [tex](x_2,y_2)[/tex]
[tex]P(x,y) = (\frac{x_1 + x_2}{2},\frac{y_1 + y_2}{2})[/tex]
[tex]P(x,y) = (\frac{7 + 0}{2} , \frac{4 + 0}{2})[/tex]
[tex]P(x,y) = (\frac{7}{2} , \frac{4}{2})[/tex]
[tex]P(x,y) = (\frac{7}{2},2)[/tex]
Hence, the coordinates of the intersection, P is [tex](\frac{7}{2},2)[/tex]

lisa drank 1/3 quart of orange juice and lane drank 1/2 quart of orange juice. how many quarts did they drink together
Answer:
[tex]\frac{5}{6}[/tex] quarts
Step-by-step explanation:
Total amount of drinks = [tex]\frac{1}{3}[/tex] + [tex]\frac{1}{2}[/tex]
You would want to make the denominators the same before adding them, so I will multiply the first fraction by 2 and the second one by 3 so their denominators are 6.
[tex]\frac{1}{3}[/tex] + [tex]\frac{1}{2}[/tex] = [tex]\frac{2}{6}[/tex] + [tex]\frac{3}{6}[/tex]
Now we can directly add them together while keeping the denominator the same.
[tex]\frac{2}{6}[/tex] + [tex]\frac{3}{6}[/tex] = [tex]\frac{5}{6}[/tex] quarts

2 years ago, age of brother was 3 times less than sister's age. this year his age is just 2 times less than his sister's. how old is brother? how old is sister?
Answer:
[tex]The\ brother's\ present\ age= 4\ years\\The\ sister's\ present\ age=8\ years[/tex]
Step-by-step explanation:
[tex]Let\ the\ brother's\ present\ age\ be\ x\\Hence\ we\ are\ given,\\His\ sister's\ present\ age=(2x)\\Now,\\The\ brother's\ age\ before\ two\ years=(x-2)\\The\ sister's\ age\ before\ two\ years=3(x-2)\\Also,\\His\ sisters\ age\ before\ two\ years=2x-2\\Hence,\\3(x-2)=2x-2\\3x-6=2x-2\\3x-2x=6-2\\x=4\\Hence,\\The\ brother's\ present\ age= 4\ years\\The\ sister's\ present\ age=2x=2*4=8\ years[/tex]
Answer:
The sister's present age is 8 years old, and the brother's present age is 4 years old.
Step-by-step explanation:
Let [tex]b =[/tex] present age of the brother, [tex]s =[/tex] present age of the sister
[tex]s-2 = (b-2)[/tex] × [tex]3[/tex]
[tex]s-2[/tex] = [tex]3b - 6[/tex]
[tex]s = 3b - 4[/tex]
[tex]s = b[/tex] × [tex]2[/tex]
[tex]= 2b[/tex]
[tex]sb-4 = 2b[/tex] (proved from above equations)
[tex]b = 4[/tex]
[tex]\because s = 3b - 4[/tex]
[tex]\therefore[/tex][tex]s = 3[/tex]×[tex]4 - 4[/tex]
[tex]= 8[/tex]
[tex]\therefore[/tex] the brother's present age is 4 years old, and the sister's present age is 8 years old.
Hope this helps :)

Answer:
Step-by-step explanation:
Equate the two opposite Angles
7x - 31 = 5x + 13 Subtract 5x from both sides
7x - 5x - 31 = 13 Combine
2x - 31 = 13 Add 31 to both sides
2x = 13 + 31 Combine the right
2x = 44 Divide by 2
x = 44/2
x = 22

What is the slope of the line parallel to y=2/5x-1?
I really need help with this fast please
Answer:
The slope will be 2/5.
Step-by-step explanation:
[tex]y = 2/5x -1[/tex] is written in slope-intercept form.
This formula looks like:
[tex]y=mx+b[/tex]
where:
M = Slope x = independent variableb = y-interceptSo:
[tex]2/5[/tex] is our slope[tex]x[/tex] remains our independent variable[tex]-1[/tex] is our y-intercept.1 ). For two lines to be parallel they must have the same slope.
Slope would remain 2/52 ). For two line to be perpendicular they must have slopes that are opposite reciprocals.
. Slope would become -5/2As the question states, we must find the slope of a line parallel to the equation given. This means that the slope will remain 2/5.
Lets check our work!
Choose a random ordered pair. I will choose (5, 6).
Now, using point slope-form we can find out if what was said above is true!
This formula looks like:
[tex]y - y1 = m (x-x1)[/tex]
Let us substitute:
[tex]y - 6 = 2/5(x-5)[/tex]
Distribute:
[tex]y-6=2/5x-2[/tex]
Add 6 to both sides:
[tex]y= 2/5x+4[/tex]
Now using both equations I will plot them on a graph to see if they a parallel.
As you can see from the graph below, these lines are parallel. Where the equation you were given is in blue and the equation I made is in red.
Based on all of the evidence, the slope will be 2/5.
Hope this helped! :)
Identify the equation in slope-intercept form for the line containing the point (2,1) and parallel to y=5/3x−1/3.
Answer:
y = 5/3x -7/3
Step-by-step explanation:
parallel lines will have the same slope
m = 5/3, point (2, 1)
use point-slope form to find the new equation for the parallel line
y - 1 = 5/3(x - 2)
y = 5/3x - 10/3 + 1
y = 5/3x -7/3
Aiden was asked to find the product of 24.5 and 7.7. His work is shown below.
Estimate: 25 x 8 = 200
Actual: 24.5 x 7.7 = 1,886.5
Which statements about Aiden’s work are true? Check all that apply.
Aiden did not make a good estimate.
Aiden should have estimated the product as 24 x 7.
Aiden did not insert the decimal point correctly when estimating.
Aiden did not insert the decimal point correctly after multiplying the actual amount.
Aiden’s estimate and the actual product do not match closely enough.

Answer:
114
Step-by-step explanation:
(400/4)+(40/4)+(16/4)
400/4=100
40/4=10
16/4=4
100+10+4=114
Answer:
all 4 for the top
456 / 4 = 114
Step-by-step explanation:
if you add up 400, 40, and 16, then you have 456. So basically if you divide them all by 4, the answer of all those numbers will equal 114

Answer:
0.5
Step-by-step explanation:
Look at the decimal go down. It goes down 0.5 each time or 1/2
The common difference in the arithmetic sequence 5.0, 4.5, 4.0, 3.5 will be 0.5.
What is the arithmetic sequence?Let a₁ be the first term and d is the common difference between the terms. Then the nth term will be given as
[tex]\rm a_n = a_1 + (n - 1)d[/tex]
The arithmetic sequence is given below.
5.0, 4.5, 4.0, 3.5

This week, Ariel ended up needing 12 gallons of gas. That is 20% more than she needed last
week. How much gas did Ariel need last week?
Answer:
10 gallons
Step-by-step explanation:
She used 12 gallons this week and used 20% more than last week. That means 12 gallons is 120% of last weeks gas. Since 12 times 10 equals 120, then to find 20% you do 20 divided 10 and subtract the answer from 12.
20% is 2 because 20 divided by 10 is 2. 12 minus 2 is 10
