Answer:

93 pieces


Step-by-step explanation:

To cover his backyard with sod, he needs to cover the area of the backyard.

His backyard is a rectangle, and area of a rectangle is given as:

A=lw

Where,

l is the length, and

w is the width

So, the area of Jim's backyard is l*w=15\frac{5}{6}*10\frac{2}{5}=\frac{95}{6}*\frac{52}{5}=\frac{494}{3} square yards.


The area of each sods are solved using the area of the rectangle formula. So we have l*w=1\frac{1}{3}*1\frac{1}{3}=\frac{4}{3}*\frac{4}{3}=\frac{16}{9} square yards as the area of each sod.


<em>To find </em><em>HOW MANY</em><em> of these sods we would need to cover the whole backyard, we divide the backyard area by each sod area:</em>

<em>\frac{\frac{494}{3}}{\frac{16}{9}}=\frac{741}{8}=92.625</em>

<u>Since, fractional sods can't be bought, Jim has to buy </u><u>93 sods</u><u> to cover his backyard.</u>

By definition, the area of a rectangle is given by:
 A = (w) * (l)&#10;
 Where,
 w: width of the rectangle
 l: length of the rectangle
 Substituting values we have:
 A = (10  \frac{2}{5} ) * (15 \frac{5}{6})&#10;&#10;A = 164.7
 Then, the area of each piece of sod is:
 A = (1  \frac{1}{3} ) * (1 \frac{1}{3})&#10;&#10;A = 1.8
 Thus, the number of pieces is given by the division of both areas:
 N = (164.7) / (1.8)&#10;&#10;N = 91.5
 Rounding the nearest whole we have:
 N = 92&#10;
 Answer:
 
Jim will need to buy 92 pieces of sod to cover his backyard

Mark gets picked up by the bus at 7:40 he arrives at school at 8:10 how long does it take to get to school
Elodia [21]
You could do this in two ways, you could either subtract immediately or convert the time given in hours into minutes
STEP 1:
8:10
- 7:40
which will give 0:30
STEP 2:
8 hours 10 minutes into minutes is
(8 * 60) +10 = 490 minutes
7 hours 40 minutes into minutes is
(7*40) + 40 = 460 minutes
490 - 460
= 30minutes

1.06(12.95+x)=31.27 solve for x
OverLord2011 [107]

Answer:

<h2>x = 16.55</h2>

Step-by-step explanation:

1.06(12.95 + x) = 31.27

<u>Multiply the terms in the bracket</u>

That's

13.727 + 1.06x = 31.27

<u>Subtract 13.727 from both sides</u>

That's

13.727 - 13.727 + 1.06x = 31.27 - 13.727

1.06x = 17.543

<u>Divide both sides by 1.06</u>

That's

\frac{1.06x}{1.06}  =  \frac{17.543}{1.06}  \\ x =  \frac{17.543}{1.06}

We have the final answer as

<h3>x = 16.55</h3>

Hope this helps you
