Answer:
98 square centimeters
Step-by-step explanation:
first find the area of the non shaded area
8x4=32
next find the area of the rectangle around it
13x10=130
and last you need to subtract the non shaded area from the rectangle around it to find the area of the shaded area
130-32=98
1/8 inch thick
inner diameter of 8.5
volume shell=volume total-volume shell
1/8=0.125
diameter/2=radius
radius inner=8.5/2=4.25
radiustotal=inner+outer=4.25+0.125=4.375
so
Vouter-Vinner=(4/3)pi4.375³-(4/3)pi4.25³
Vshell=(4/3)(pi)(4.375³-4.25)
Vshell=(4/3)(pi)(83.740234375-76.765625)
Vshell=(4/3)(pi)(6.974609375)
Vshell=9.299479166666666666666pi cubic inches
Vshell≈16.433536180619 cubic inches
Answer: conjecture
Step-by-step explanation:
A conjecture is a statement or an opinion based on logical reasoning or trivial facts that are always true. It does not require any proof.
Thus, A <u>conjecture</u> is a statement that you conclude to be true based on logical reasoning.
Note:
- Conclusion = Result made after a generalized study.
- Argument = A series of reasons that leads to a conclusion.
- proof = An argument that uses written justification in the form of definitions, properties, postulates, and previously proved theorems.
A certain allergen affects approximately 7 people per 10,000 in the United States. Assuming the U.S. population is approximately 324 million people, how many people suffer from this allergen?

<u>2 red marbles = x red marbles </u>
7 blue marbles = 117 blue marbles <<<PROPORTION
(total) (total)
<u>117x2 = 234 </u>
7 = 7 <<< = 33.42857143
here's a simpler way of writing that>>> 33.4 or 33
