Answer:
area of circle having radius 3
is πr²=π*3²=9π square units
area of circle having radius 2
=πr²=π×2²=4π square units
again
area of big circle having radius [3+2]=5 units
=πr²=π×5²=25π square units
Now
area of shaded region=25π-4π-9π=12π or 37.7square units.
Answer:
12π units² or 37.7 units²
Step-by-step explanation:
Find the area of the 3 circles and subtract the areas of the two smallest ones.
Biggest circle area: π((3(2)+2(2))/2)² = π((6+4)/2)² = π(5²) = 25π units²
2nd Biggest circle area: π(3)² = 9π units²
Smallest circle area: π(2)² = 4π units²
Shaded area: 25π - (9π + 4π) = 25π - 13π = 12π units² or 37.7 units²

Answer:
3¹²
Step-by-step explanation:
First lets simplify:
(3⁵)² would be 3¹⁰
and 3⁻² would stay the same:
Now;
[tex]\frac{3^{10} }{3^{-2} }[/tex]
Now keep the base same and subtract exponents:
10 - (-2) = 12
=> Therefore the answer would be 3¹²
Hope this helps!
Answer:
3¹²
Step-by-step explanation:
This kinda Questions can be done using the Law of exponents as ,
[tex] a^m \div a^n = a^{m-n}[/tex][tex] (a^n)^m = a^{mn}[/tex]So using these properties we have ,
→ (3⁵)² / 3-²
→ 3¹⁰ / 3 -²
Now we will use the first formula stated above . That will Result the exponent into , 10 - (-2) = 10 + 2 = 12 . Hence ,→ 3¹²
• Hence the required answer is 3¹² .can someone please help me on this question? 30 points

How do you find the radius of a Tetrahedron?
My own question no answer choices.
No bit links plz. 15 points and plz describe well.
Answers
Answer:
The center of the tetrahedron divides each of the four heights (or medians) in the ratio 1:3 (in an equilateral triangle the corresponding ratio is 1:2). The smaller part is also the radius of the inscribed sphere. Therefore the radius of this sphere is one quarter of the height or 9 in your case.

Definition of fraction:In mathematics, a fraction is used to represent a portion of something larger. It represents the whole's equal pieces. The numerator and denominator are the two elements of a fraction. The numerator is the number at the top, and the denominator is the number at the bottom. The numerator specifies the number of equal parts taken, whereas the denominator specifies the total number of equal parts in the total.
5/10, for example, is a fraction.
The numerator is 5 and the denominator is 10.

Samantha saves at least 10% of the money she earns each month. She earns $120 each month for a year. Which inequality describes the total amount Samantha saves?
Answers
Step-by-step explanation:
10 % each month is $12.00 12 months in a year 12 x 12.00 = $144.00
The inequality to describe the total amount Samantha saves is s > 15.
The correct option is (A).
What is Inequality?Inequalities are mathematical formulas in which neither side is equal. We compare two values in inequality.
As per the given data:
We are given that Samantha saves at least 10% of her monthly salary.
Samantha is earning $150 each month for a year.
To find the amount Samantha at least saves in a month:
= 10% of her monthly salary
= 10% × 150
= 10/100 × 150
= 15 dollars
As she is saving, at least 15 dollars, then the inequality to describe her savings is as follows:
savings > 15
The inequality to describe the total amount Samantha saves is s > 15.
Hence, The inequality to describe the total amount Samantha saves is
s > 15.
