If a sprinkler waters 1 over 12 of a lawn in 1 over 2 hour, how much time will it take to water the entire lawn? 7 over 12 hour, 1 over 6 hour, 6 hours, 10 hours

Answers

Using proportions, it is found that it takes 6 hours to water the entire lawn.

This question is solved by proportions, using a rule of three.

The sprinkler waters $(1)/(12)$ of the lawn in $(1)/(2)$ of an hour. How long it takes to water the entire lawn, which is equivalent to 1?

The rule of three is:

$(1)/(12)$ lawn - $(1)/(2)$ hour

1 lawn - x hours

Applying cross multiplication:

$(1)/(12)x = (1)/(2)$

$2x = 12$

$x = (12)/(2)$

$x = 6$

It takes 6 hours to water the entire lawn.

Step-by-step explanation:

Josiah invests $360 into an account that accrues 3% interest annually. Assuming no deposits or withdrawals are made, which equation represents the amount of money in Josiah’s account, y, after x years?

Answers

The future amount of money that is invested currently at a certain interest that is compounded annually is calculated through the equation,
F = P x (1 + i)^n
where F is the future worth, P is the present worth, i is the interest rate, and n is the number of years. Substituting the known values and variables in the given, F = ($360)(1.03)^x

Answer: $y = 360(1.03)^x$

Step-by-step explanation:

Since, the principal amount of the money = $ 360

Annual rate of interest = 3%

Thus, the amount after x years which is increased by 3 %,

$= 360(1+(3)/(100) )^x$

$= 360(1+0.03 )^x$

$= 360(1.03 )^x$

Since, this amount represented by y,

Thus, the required equation that represents the amount of money in Josiah’s account, y, after x years is,

$y = 360(1.03 )^x$

Please I REALY NEED HELPTriangle ABC is similar to triangle LMN by the AA Similarity Postulate.

Also, m∠A = 108° and m∠C = 2(m∠M).

What is m∠M?

_________ °

Answers

since two of the triangles are similar that means they are the same thing :
<A = <L
108 = 108

<C is twice from <M so :
<C is 2x                 < M is x

as you note down the answer you can draw two triangles and label them according to thier values, you will see that triangle ABC has two things now ;
                                                           a = 108   and   c = 2x
when you have two measures in a triangle you can find the 3rd one :
suppose that third < of triangle ABC is x ;
108 + 2x + x = 180
108 + 3x = 180
3x = 180 - 108
3x = 72
x = 24

                                          <m = 24

further if you want to find C :
                                          < c = 2x
                                      < c = 2 ( 24 )
                                       < c = 48
