The complete question in the attached figure
we know that
[area of a circle]=pi*r²
for r=1 unit
[area of a circle]=pi*1²---------> pi units²
if the area a full circle of 360°--------------> is pi
the area of sector 88°------------------------> X
X=88*pi/360--------> 0.77 units²
the answer is
<span>
the area of sector AOB is 0.77 units</span>
²
To answer this item, we let x be the number of eggs in the beginning. The first half of the egg which were not boiled is represented through the equation is represented by x/2.
Next, the remainder of the egg which were not boiled nor poached is equal to
= (1/2)(3/4)x
Simplifying,
0.375x
Equating this to 9,
0.375x = 9
The value of x from the equation is 24.
Answer: 24 eggs
-12 would be it because 2 negatives make a positive so -11+23 is -12
the value of c that makes the expression a perfect square binomial is c=4 .
<u>Step-by-step explanation:</u>
Here we have , an expression x2 + 4x + c or ,
. We need to find the value of c that makes the expression a perfect square binomial. Let's find out:
We have , 
⇒ 
⇒ 
Now , we know that 
Comparing above equation , to
we get ;
⇒
{
}
⇒ 
⇒ 
Therefore , the value of c that makes the expression a perfect square binomial is c=4 .
