The figure below shows a shaded circular region inside a larger circle:
r3 inches
R5 inches
What is the probability that a point chosen inside the larger circle is not in the shaded region?
O 24%
O 36%
O 50%
O 64%

Answers

Answer 1

Answer:

Probability is 64%

Step-by-step explanation:

Given the smaller circle which is shaded whose radius is denoted by r and  the largest circle whose radius is denoted by R

                     r = 3 inches

                    R = 5 inches

Step 1 : To calculate the area of shaded region.

Area of circle =

⇒ Area =    

          =   square inches

Step 2 : To calculate the area of larger circle.

Area of circle =

⇒ Area =    

            =  square inches

Step 3 : Calculate the probability that a point chosen from shaded region

Probability = Area of shaded region/Area of larger circle.

                  =  /

                  =  

                  =  0.36 = 36%

Step 4 : calculate the probability that a point chosen inside the larger circle is not in shaded region.

Probability = 1 - 0.36

                  = 0.64 = 64%

Hence the probability is 64%

please help

Answers

Answer:

The next operation that should be carried out after (9 + 6) in the given expression is; a division which is (9 + 6) ÷ 5.

How to carry out mathematical operations?

We want to carry out the mathematical expression;

122 + 10 × 2 − (9 + 6) ÷ 5

From BODMAS Acronym, the first operation is Bracket, then of then division, then Multiplication, then Addition, then subtraction.

Now, the first operation is the one in the bracket which is 9 + 6 = 15.

Thereafter, the second operation to carry out is the division which is 15 ÷ 5 = 3.

Answers

Answer:

840cm²

Step-by-step explanation:

The two small triangle areas:

b × h / 2 = 12 × 5 = 60 / 2 = 30cm²

So two triangles would be 60cm²

Now, for the top rectangle:

b × h = 26 × 12 = 312cm²

The middle rectangle:

b × h = 26 × 13 = 338cm²

And the bottom last triangle:

b × h = 26 × 5 = 130cm².

Now to add them all: 60 + 312 + 338 + 130 = 840cm²

I advice you to just check to make sure the calculations were right! Good luck with the rest of your finals :)

It would be 840

One company makes inflatable swimming pools that come in four sizes of rectangular prisms.

The length of each pool is twice the width and twice the depth.

The depth of each pool is a whole number from 5 to 8 feet.

If the pools are filled all the way to the top, what is the volume of each pool?

Answers

Answer:

The widths and depths are the same. Since volume is length x width x height, you get 2x2x4=16, 3x3x6=54, 4x4x8=128, 5x5x10=250

Triangle HIJ is dilated by a scale factor of 55 to form triangle H'I'J'. Side I'J' measures 7575. What is the measure of side IJ? (marking brainliest)

Answers

Answer:

If triangle HIJ is dilated about the center of the triangle to create triangle H'I'J', dilated line A'B' will be parallel to AB.Option (D) is correct.

Given:

The options are as follows,

(A). be perpendicular to AB.

(B). lie on the same line as AB.

(C). shift four units to the left.

(D). be parallel to AB.

Step-by-step explanation:

If we dilate triangle HIJ then the dilated triangle  is bigger than the triangle HIJ.

The triangle HIJ is similar to triangle  to each other.

So the line  is parallel to side AB.
