a foot is 12 inches, a yard is 3 feet, so a yard is then 3*12 inches, or 36 inches.

Regina used <u>24 out of 36</u> inches, so ........\bf \cfrac{24}{36}\implies \cfrac{2}{3}

If you can mow 90 lawns in 45 hours, how long will it take to mow 12?
Alex777 [14]
<h3>Answer:  6 hours</h3>

Work Shown:

(90 lawns)/(45 hours) = (12 lawns)/(x hours)

90/45 = 12/x

2 = 12/x

2x = 12

x = 12/2

x = 6

It takes 6 hours to mow 12 lawns.

one interior angle of a polygon is a right angle and each of the other interior angles is 126°. Calculate the number of sides of
Vikentia [17]

Answer:

There are 7 sides.

Step-by-step explanation:

Let's Use the formula that states that the sum of the angles of an n-sided polygon is given by.

S=(n−2)180

Since we are given that the two angles are right, the angles and each of the remaining angles is 144.

And Therefore, the sum is:

S=90

(n−2)144

(n−2)180

=90

+90

+(n−2)144

⇒(n−2)180

−(n−2)144

=180

⇒(n−2)(180

−144

)=180

⇒(n−2)(36

=180

⇒n−2=

36

180

​⇒n−2=5

⇒n=5+2=7

Hence, the polygon has 7 sides.

Whats the answer to 1/5x=121 x=?
weqwewe [10]
You have an algebraic expression in which you are solving for x.  When you are solving for a variable, you need to isolate it all alone.  Since you are multiplying by 1/5, you will have to undo it by multiplying by its reciprocal.  In this case you are multiplying both sides by 5/1.

5/1 *1/5x = 121*5/1
x = 605

To check your answer, plug this value in for x and multiply it by 1/5.  You should arrive at 121!  Good luck!
