Given m ll n,
find the value of x and y.
Can someone answer this today please
Answer:
x = 15, y = 50Step-by-step explanation:
m and n are parallel and cut by a transversal
Finding x
8x + 12 + 2x + 18 = 180 (consecutive interior angles sum up to 180°)10x + 30 = 18010x = 150x = 15Finding y
8x + 12 = 3y - 18 (vertical angles are equal)8(15) + 12 = 3y - 18132 = 3y - 18150 = 3yy = 50Simplyfiy3 3/4 x 1 1/5

To save costs dylan decides to decrese the size of the house she is building . Orginally the plans for the house show the dimensions of the house pad to be 20 ft by 30 ft . She reduces each dimension by 10 percent
Answer:
[tex]Length = 18[/tex]
[tex]Width = 27[/tex]
Step-by-step explanation:
Given
Dimension = 20 by 30
Reduction = 10%
Required
Determine the new dimensions
Because it is a reduction, the new dimension is calculated using:
[tex]New = Old (1 - Reduction)[/tex]
The new length is calculated as:
[tex]Length = 20(1 - 10\%)[/tex]
Convert percentage to decimal
[tex]Length = 20(1 - 0.10)[/tex]
[tex]Length = 20 * 0.90[/tex]
[tex]Length = 18[/tex]
The new width is calculated as:
[tex]Width = 30(1 - 10\%)[/tex]
Convert percentage to decimal
[tex]Width = 30(1 - 0.10)[/tex]
[tex]Width = 30*0.90[/tex]
[tex]Width = 27[/tex]

A computer was on sale for 270 if the original price was cut by 40% what was the original price
explain.
Answer: 108
Step-by-step explanation: The 40% percent taken away from $270 would be $108, because I round it to 50% percent off and that would $135 but since it's 40% off not 50% so I took away 10% from $135, and that's how I found my answer .

It would negative because 70 is a negative integer while 7 is positive and positive multiplied with negative is a negative
Answer:
The sign of the product is positive.
Step-by-step explanation:
Suppose, two negative integers are (-x) and (-y). Then their product will be xy which has a positive sign.
Again take two integers -x, -y and -z. Their product is -xyz.
It means, if positive number of negative integers are multiplied, the result is positive whereas the product of negative number of negative integers is negative.

Step-by-step explanation:
A boat is pulled into a dock by a rope with one end attached to the front of the boat and the other end passing through a ring attached to the dock at a point 5 feet higher than the front of the boat. The rope is being pulled through the ring at the rate of 0.6 ft/sec. How fast is the boat approaching the dock when 13 feet of rope are out
Answer:
The boat is approaching the dock at 0.65 ft/sec when 13 feet of rope are out.
Step-by-step explanation:
Let x be the length of rope and y be the distance between boat and dock.
Height of point where a ring attached =z=5 feet
[tex]\frac{dx}{dt}=-0.6ft/sec[/tex]
x=13 feet
Using Pythagoras theorem
[tex]H^2=P^2+B^2[/tex]
[tex]x^2=z^2+y^2[/tex]
[tex]x^2=5^2+y^2=25+y^2[/tex]
[tex](13)^2=25+y^2[/tex]
[tex]169-25=y^2[/tex]
[tex]144=y^2[/tex]
[tex]y=12 feet[/tex]
Differentiate w.r.t t
[tex]2x\frac{dx}{dt}=2y\frac{dy}{dt}[/tex]
[tex]x\frac{dx}{dt}=y\frac{dy}{dt}[/tex]
[tex]13(-0.6)=12\frac{dy}{dt}[/tex]
[tex]\frac{7.8}{12}=\frac{dy}{dt}[/tex]
[tex]\frac{dy}{dt}=-0.65feet/sec[/tex]
Hence,the boat is approaching the dock at 0.65 ft/sec when 13 feet of rope are out.

The perimeter of a rectangle is 154 cm. The ratio of the length to the width is 10: 1. Find the length and the width
Answer:
length=70cm
width=7cm
Step-by-step explanation:
total ratio=10 + 1
=11
length(2)=10/11 x 154 cm
=10 x 14cm
=140cm
one length is 140 cm/2=70cm
width(2)=1/11 x 154cm
=14cm
one width is 14cm/2=7cm
The length and the width should be considered as the 70 cm and 7 cm.
Calculation of the length and width:Since
The perimeter of a rectangle is 154 cm.
The ratio of the length to the width is 10: 1.
So here total ratio=10 + 1
=11
Now length 2 should be
=10/11 x 154 cm
=10 x 14cm
=140cm
So,
one length is 140 cm/2=70cm
Now
width(2)=1/11 x 154cm
=14cm
And,
one width is 14cm/2=7cm
hence, The length and the width should be considered as the 70 cm and 7 cm.

HELP PLS 19 and 40 degrees
Answer:
x ≈ 14.6
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos40° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{x}{19}[/tex] ( multiply both sides by 19 )
19 × cos40° = x , then
x ≈ 14.6 ( to the nearest tenth )
The five marathon runners weigh an average weight of 92 pounds, Nicole weighs 89 pounds, Jon weighs 95 pounds, Jenny and Kim weigh 90 pounds each, How much does Jordin weigh?
Answer:
Jordin weighs 96 pounds
Step-by-step explanation:
The Mean Value of a Data Set
The mean or average of a data set is found by adding all numbers and then dividing by the number of values in the set. Written as a formula:
[tex]\displaystyle \bar x=\frac{\sum x_i}{n}[/tex]
Where xi is the value of each data and n is the total number of values.
We are given the average weight of n=5 marathon runners:
[tex]\bar x=92[/tex]
Multiplying the formula by n and expanding the sum:
[tex]n\bar x=\sum x_i=x_1+x_2+x_3+x_4+x_5[/tex]
We are given the weighs of four of the runners:
[tex]5*92=89+95+90+90+x_5[/tex]
[tex]460=364+x_5[/tex]
Solving for x5:
[tex]x_5 = 460-364=96[/tex]
Jordin weighs 96 pounds
