The radius of a circle is 1 inch. What is the area of a sector bounded by a 135° arc?

Answers

Answer 1

Answer:

http://www.1728.org/radians.htm

The area of a sector = (central angle /360°) * PI * radius^2

area = (135 / 360) * 3.14159265 * 1 * 1

area = .375 * 3.14159265 * 1

area = 1.17809724 square inches

How many blue pens were there to start with?

Answers

Answer:

180 blue   70 red

Step-by-step explanation:

b= blue      r = red

b+r = 250

r = (250-b)

If 40% is removed the rest is 60%

If the 70% is removed the rest is 30%

0.6b + 0.3(250-b)  = 129

0.6b + 75 - 0.3b = 129

  0.3b = 54

divide by 0.3

  b = 180

    250-180 =  70

   60% 0f 180 = 108

   30% of 70 = 21

   108 +21 = 129

you

Answer:

942 mm 3

Step-by-step explanation:

Since 1.2 cm isn't mm we have to convert that, which will be 12. now we do the formula, which is

V=3.14 x r2 x h

and when we plug in the numbers,

V=3.14 x 25 (5x5) x 12

which is 942

In ΔUVW, the measure of ∠W=90°, VW = 32 feet, and WU = 78 feet. Find the measure of ∠V to the nearest degree.

Answers

Answer: [tex]67.68^{\circ}[/tex]

Step-by-step explanation:

Given

[tex]\angle W=90^{\circ}[/tex]

[tex]VW=32\ ft[/tex]

[tex]WU=78\ ft[/tex]

from the figure, we can write

[tex]\Rightarrow \tan v=\dfrac{UW}{VW}\\\\\Rightarrow \tan v=\dfrac{78}{32}\\\\\Rightarrow \tan v=2.437\\\Rightarrow v=\tan^-1(2.437)\\\Rightarrow v=67.68^{\circ}[/tex]

3) Six teams are playing in a baseball tournament. In how many ways can the teams be crowned champion and
runner-up?

Answers

Answer:

15ways

Step-by-step explanation:

This question bothers combination

Combination has to do with selection

Given

Total number of teams  = 6

champion and runner up = 2

number of ways is expressed as 6C2

6C2 = 6!/(6-2)!2!

6C2 = 6!/4!2!

6C2 = 6*5*4!/4!*2

6c2 = 30/2

6C2 = 15

Hence the number of ways they can be selected is 15ways
