Find the area of the circle use 3.14 for pie do not round your answer

Answers

Answer:

Area= 12.56 inches²

Step-by-step explanation:

To find the area of a circle: A= πr²A= 3.14 × 2²A= 3.14 × 4A= 12.56 inches²

[tex]\tt{ \green{P} \orange{s} \red{y} \blue{x} \pink{c} \purple{h} \green{i} e}[/tex]

The area is:

12.56 in²

Work/explanation:

The formula for the area of a circle is:

[tex]\sf{A=\pi r^2}}[/tex]

Where

A = area

π = 3.14

r = radius

Diagram:

[tex]\setlength{\unitlength}{1cm}\begin{picture}(0,0)\thicklines\qbezier(2.3,0)(2.121,2.121)(0,2.3)\qbezier(-2.3,0)(-2.121,2.121)(0,2.3)\qbezier(-2.3,0)(-2.121,-2.121)(0,-2.3)\qbezier(2.3,0)(2.121,-2.121)(-0,-2.3)\put(0,0){\line(1,0){2.3}}\put(0.5,0.3){\bf\large 2\ in}\end{picture}[/tex]

Plug in the data:

[tex]\sf{A = 3.14 \times 2^2}[/tex]

[tex]\sf{A = 3.14 \times 4}[/tex]

[tex]\sf{A = 12.56\:in^2[/tex]

Hence, the answer is 12.56 in².

After a band parent meeting, each of
the ten members shook hands with
each other once. How many
handshakes were there in all?
Hint: Remember that one handshake involves
two people.
[?] handshakes

Answers

The question is asking how many combinations of two people can be made from a group of ten people.

Using the formula C(10,2) = 10!/(2! x (10 - 2)! = 10!/(2! x 8!) = 45 handshakes.

A simple way to prove this is each person shakes the hand of 9 other people
10 x 9 = 90 but this counts every handshake from the view of both people involved.
The actual number of handshakes is therefore 90 / 2 = 45

Of the 121,301,000 men in the U.S., 3.38% didn’t complete 9th grade. How many men is this?

Answers

Answer:

4099973

Step-by-step explanation:

I hope this is correct! :)

Sorry if I'm wrong...

Approximately 4,100,938 men in the U.S. didn't complete 9th grade. To find out how many men in the U.S. didn't complete 9th grade, we can use the percentage given and calculate it as follows: Number of men who didn't complete 9th grade = (Percentage of men who didn't complete 9th grade / 100) * Total number of men in the U.S.

Given:

Percentage of men who didn't complete 9th grade = 3.38%

Total number of men in the U.S. = 121,301,000

Let's calculate:

Number of men who didn't complete 9th grade = (3.38 / 100) * 121,301,000

Number of men who didn't complete 9th grade ≈ 4,100,938

So, approximately 4,100,938 men in the U.S. didn't complete 9th grade.

P(x) = x^4+ax^3-x^2+bx-12 has factors of (x-2) and (x+1). Solve the equation P(x)=0​

Answers

Answer:

because P(x) has factors of (x-2) and (x+1) => x = 2 and x = -1 are the solutions of P(x)

so we have:

[tex]\left \{ {{2^{4}+2^{3}a-2^{2}+2b-12 =0} \atop {1-a-1-b-12=0}} \right.\\=>\left \{ {{8a+2b=0} \atop {a+b=-12}} \right.\\<=>\left \{ {{4a+b=0} \atop {a+b=-12}} \right.\\<=>\left \{ {{a=4} \atop {b=-16}} \right.[/tex]

=> [tex]P(x)=x^{4} + 4x^{3}-x^{2} -16x-12[/tex]

28. Retail Sara Sung is shopping and finds several items that are on sale at 25% off
the original price. The items that she wishes to buy are a sweater originally at
$43.98, a pair of jeans for $38.59, and a blouse for $31.99. She has $100 that her
grandmother gave her for her birthday. If the sales tax in San Mateo, California,
where she lives is 8.25%, does Sara have enough money for all three items?
Explain.

Answers

Answer:

Sara has enough money to buy all three items because after the sale and tax, the total of all three items is less than $100 at only $93.01.

Step-by-step explanation:

Solve for the sale:

43.98 × 0.25

10.995

38.59 × 0.25

9.6475

31.99 × 0.25

7.9975

Add these all together:

10.995 + 9.6475 + 7.9975

28.64

Subtract this amount from the original cost of all the items:

(43.98 + 38.59 + 31.99) - 28.64

114.56 - 28.64

85.92

Solve for the sales tax:

85.92 × 0.0825

7.0884

Add the sales tax to the total:

85.92 + 7.0884

93.0084

Round up to the nearest cent:

93.01

93.01 < 100
