Answer:
Easy
Step-by-step explanation:
To find the perimeter, add all the sides together.
12+16+20=48
To find the area, you multiply the sides that make the right angle of the triangle,
12×16=192
And divide it by two. This step is important as if you don't divide it by two, you will end up with the area of a square.
192÷2=96
Finito. Oh and don't forget to add units.
Cm for perimeter and Cm(squared) for area. :)
Solutions
1) <span>Add the whole numbers first ( 7 and 2 )
</span><span>9+<span>7/8</span>+<span>11/12
2) </span></span>Find the Least Common Denominator (LCD) of
<span><span>7 / 8</span>,<span>11 / 12
</span></span>
Start by Listing Multiples
List out all multiples of each denominator, and find the first common one.
8 : <span><span>8,16,24</span>
</span>
12 : <span>12,24
</span>
Therefore, the LCD is <span>24
</span>Method 2: By Prime Factors
List all prime factors of each denominator, and find the union of these primes.
8 : <span>2,2,2
</span>
12 : <span>2,2,3
</span>
Therefore, the LCD is <span>2×2×2×3=24
3) </span>Make the denominators the same as the LCD
<span>9+<span><span>7×3 / </span><span>8×3</span></span>+<span><span>11×2 / </span><span>12×2
</span></span></span>4) Simplify. Denominators are now the same
<span>9+<span>21 / 24</span>+<span>22 / 24
5) J</span></span>oin the denominators
<span>9+<span><span>21+22 / </span>24</span></span>
6) Simplify
<span>9+<span>43 / 24
7) </span></span>Convert 43 / 24 <span>to mixed fraction
</span><span>9+1 <span>19 / 24
8) </span></span>Simplify
<span><span>10 <span>19 / 24</span></span></span>

y = 12000x + 35000
When Mr. Nicolas began recording, it means, at 0 hour, how many tortillas was produced?
Subs x by 0.
y = 12000.0 + 35000
y = 0 + 35000
y = 35000
When Mr. Nicolas began recording the data, 35,000 tortillas had already been produced
The total number of tortillas produced 2 hours after the he began, it means, when x = 2
y = 12000 . 2 + 35000
y = 24000 + 35000
y = 59000
The total number of tortillas produced 2 hours after he began recording the data was 59,000
The total number of tortillas produced _ hours after he began recording the data was 85,000
Now we have y but not x.
y = 12,000x + 35,000
85,000 = 12,000x + 35,000
85,000 - 35,000 = 12,000x
50,000 = 12,000x
x = 50/12
x = 25/6
x = 4,1666...
Rounding
x = 4,167
