Maria is tracking the number of miles she runs in one week. She is using the track at her age hook which measures in meters.

attashe74 [19]

Using proportions, it is found that she runs 3.106855 miles in one week.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

Researching this problem on the internet, it is found that the measurement is in meters, and we want to find the number of miles. She runs 5,000 meters. Each meter has 0.000621371 miles, hence the number of miles that she runs is given by:

M = 5000 x 0.000621371 = 3.106855 miles .

Maria runs 3.106855 miles in one week.

x - y = 3 x + y = 5 Which of the following systems is equivalent to the given system? 2x - y = 18 and x + 2y = 10 4x - 3y = 18 a

tiny-mole [99]

Answer:

None of the systems is equivalent to the given system

Step-by-step explanation:

we have the given system

$x-y=3$ ---> equation A

$x+y=5$ ---> equation B

Solve the system

Adds equation A and equation B

$x-y=3\\x+y=5\\------\\ 2x=8\\x=4$

Find the value of y

$(4)-y=3$ ------> $y=4-3=1$

The solution of the given system is the point (4,1)

we know that

If a system is equivalent to the given system, then the solution of both systems must be the same

Verify each case

case A) 2x - y = 18 and x + 2y = 10

$2x-y=18$ ---> equation A

$x+2y=10$ ---> equation B

Substitute the value of x and y in both equations and then compare the results

$x=4,y=1$

equation A

$2(4)-(1)=18$

$7=18$ ----> is not true

therefore

the system is not equivalent to the given system

case B) 4x - 3y = 18 and x + 2y = 10

$4x-3y=18$ ---> equation A

$x+2y=10$ ---> equation B

Substitute the value of x and y in both equations and then compare the results

$x=4,y=1$

equation A

$4(4)-3(1)=18$

$13=18$ ----> is not true

therefore

the system is not equivalent to the given system

case C) 2x - 3y = 3 and x + 2y = 5

$2x-3y=3$ ---> equation A

$x+2y=5$ ---> equation B

Substitute the value of x and y in both equations and then compare the results

$x=4,y=1$

equation A

$2(4)-3(1)=18$

$5=18$ ----> is not true

therefore

the system is not equivalent to the given system

Convert the polar equation to rectangular coordinates. (Use variables x and y as needed.)

Vika [28.1K]

I will list first the important conversions and identities that are essential for the solution:

r^2 = x^2 + y^2
x = rcostheta
y = rsintheta

These are the equations when you convert between rectangular and polar coordinates. Also csc theta = 1/sin theta fromtrigo identities. Thus, substituting these equations would yield:

r = 7 csctheta
r = 7/sin theta
√(x^2 + y^2) = 7/(y/r)
√(x^2 + y^2) = 7r/y
y√(x^2 + y^2) = 7r
