Answer:
sqrt(21)
Step-by-step explanation:
x = sqrt(7*3) = sqrt(21)
To solve this problem you must follow the proccedure below:
a<span>. Find the perimeter and area of the cracker remaining:
The perimeter of a quarter circle is:
P=(</span>πr/2)+2r
P=(πx3 cm/2)+2(3 cm)
P=10.71 cm
The perimeter of <span>the cracker remaining is:
</span><span>
Pt=3 cm+6 cm+3 cm+10.71 cm
Pt=22.71 cm
The area of a quarter circle is:
A=</span>πr²/4
A=π(3 cm)²/4
A=7.06 cm²
<span>
The area of</span><span>of the cracker remaining is:
</span><span>
At=Area of a square-Area of quarter circle
At=L</span>²-(πr²/4)
At=(6 cm)²-(π(3 cm)²/4)
At=28.93 cm²
<span>
b. About how many bites can you get from the entire cracker?</span>
Number of bites=L²/(π(3 cm)²/4)
Number of bites=5
The answer is 24. think of x as the original amount, and y as the new
amount. y times 1.5 is x, and y+12 is x. reverse that to figure out y,
which is what we need, and you have x/1.5 = y as well as x-12 = y. Use
the equal values method and make an equation x/1.5=x-12. solve this
equation to get x, which is 36. to figure out the new amount, y, you
need to subtract 12, which would help you get 24 as your final answer.
