The store sold 4 packs of 2 because if they sold 3 packs of 5 that would be 15 then 4 packs of 2 would be 8 and 3 plus 4 is 7 and 15 plus 8 is 23

boyakko [2]

Note that,

9x^2+24x+20=4\Longrightarrow9x^2+24x+16

Which factors to,

(3x+4)^2=0\Longrightarrow3x+4=0

And simplifies to <u>solution C</u>,

\boxed{x=-\dfrac{4}{3}}

Hope this helps.

PLZ HELP ASAP AREA OF A SECTOR
tigry1 [53]
The relationship of arcs is:
 S '/ S = ((2/5) * pi * r) / (2 * pi * r)
 Rewriting we have:
 S '/ S = ((2/5)) / (2)
 S '/ S = 2/10
 S '/ S = 1/5
 Therefore, the area of the shaded region is:
 A '= (S' / S) * A
 Where A: area of the complete circle:
 A '= (1/5) * 100 * pi
 A '= 20 * pi
 Answer:
 
The area of the shaded region is:
 A '= 20 * pi

Estimate the circumference of the circular base of the object. Round to the nearest hundredth if necessary.
Lubov Fominskaja [6]

Answer: C\approx3.14\ mm

Step-by-step explanation:

The circumference of a circle can be calculated with the formula shown below:

C=2\pi r

Where "C" is the circumference of the circle and "r" is the radius.

In this case, according to the information given in the exercise, you know that the radius of the circular base of the object is the following:

r=0.5\ mm

Then, knowing the value of "r", you can substitute it into the formula shown at the beginning of this explanation:

C=2\pi (0.5\ mm)

And finally, evaluating and rounding the result to the nearest hundredth, you get that the circumference of the circular base is approximately:

C=\pi \ mm\\\\C\approx3.14\ mm
