I need e-learning help ugh ... ASAP

miskamm [114]

Answer:

600 m

Step-by-step explanation:

You know that she walks 1 meter in 1 second, but they're asking about minutes. Since 60 seconds are in 1 minute, it means she was 60 meters in 1 minute. Then multiply that by 10 (10 minutes).

She walked 600 meters, in 10 minutes.

I hope this helped!

An equation parallel and perpendicular to 4x+5y=19

UNO [17]

Answer:

Parallel line:

$y=-\frac{4}{5}x+\frac{9}{5}$

Perpendicular line:

$y=\frac{5}{4}x-\frac{1}{2}$

Step-by-step explanation:

we are given equation 4x+5y=19

Firstly, we will solve for y

$4x+5y=19$

we can change it into y=mx+b form

$5y=-4x+19$

$y=-\frac{4}{5}x+\frac{19}{5}$

so,

$m=-\frac{4}{5}$

Parallel line:

we know that slope of two parallel lines are always same

so,

$m'=-\frac{4}{5}$

Let's assume parallel line passes through (1,1)

now, we can find equation of line

$y-y_1=m'(x-x_1)$

we can plug values

$y-1=-\frac{4}{5}(x-1)$

now, we can solve for y

$y=-\frac{4}{5}x+\frac{9}{5}$

Perpendicular line:

we know that slope of perpendicular line is -1/m

so, we get slope as

$m'=\frac{5}{4}$

Let's assume perpendicular line passes through (2,2)

now, we can find equation of line

$y-y_1=m'(x-x_1)$

we can plug values

$y-2=\frac{5}{4}(x-2)$

now, we can solve for y

$y=\frac{5}{4}x-\frac{1}{2}$

kap26 [50]

Answer:

<u>13</u> months attended the club.

Step-by-step explanation:

Given:

In order to join a dancing club there is a $30 startup fee and a $4 monthly fee. If you joined the club and spent $82.

Now, to find the months attend the club.

Startup fee = $30.

Monthly fee = $4.

Total money spent = $82.

So, we deduct the startup fee from the total money spent:

$82-30$

$=\$52.$

The remaining amount is $52.

Now, we divide the monthly fee by the remaining amount to get the months attended:

$52\div 4$

$=13.$

Therefore, 13 months attended the club.

The rule of 72 that represents the annual interest rate is defined below , the rate is 4.5% .

In the question ,

it is given that ,

Miguel is planning to retire after 16 years ,

and he wants to double his money ,

The Rule of 72 is a simplified formula , that is used to calculate the time that an investment will take to double the value , based on its rate of return .

By the rule of 72 ,

Number of years that would take an investment to double = 72/(rate of interest )

n = 72/r

given the time is 16 years .

16 = 72/r

r = 72/16

r = 4.5%

Therefore , The rule of 72 that represents the annual interest rate is defined below , the rate is 4.5% .
