If a point is chosen inside the square, what is the probability that it will also be inside the circle?

Answers

Answer:

[tex]79\%[/tex]

Step-by-step explanation:

The probability that the point is chosen in the circle is equal to the area of the circle divided by the area of the square.

Formulas used:

Area of a square with side length [tex]s[/tex] is given by [tex]A=s^2[/tex] Area of a circle with radius [tex]r[/tex] is given by [tex]A=r^2\pi[/tex]

The segment marked as 1 represents not only the radius of the circle, but also half the side length of the square. Therefore, the side length of the square is 2, and we have:

Area of square: [tex]A=2^2=4[/tex]

Area of circle:

[tex]A=1^2\pi=\pi[/tex]

Therefore, the probability that the point will be inside the circle is:

[tex]\frac{\pi}{4}=0.78539816339\approx \boxed{79\%}[/tex]

They gave you the length of the two sides of the triangular part. Calculate the circumference of the semi circle on top.

Circumference of a semi circle is 1/2 x 2 x radius x PI

The radius is given as 3 ft.

Circumference  = 1/2 x 2 x 3 x 3.14 = 9.42ft

Perimeter is the length of the circumference of the semi circle plus the side lengths of the triangle:

if (a+10) and (a+20)are supplementary angles,find them​

Answers

Given:

(a+10) and (a+20) are supplementary

To find:

Each angle

Steps:

if 2 angles are supplementary that means they add up to 180°

(a + 10) + (a + 20) = 180

   a + 10 + a + 20 = 180

              2a + 30 = 180

                      2a = 180 - 30

                      2a = 150

                        a = 150/2

                        a = 75°

Now let's find value of each angle,

a + 10 = 75 + 10

          = 85°

a + 20 = 75 + 20

           = 95°

Therefore, the value of each angle is 85° and 95° respectively

On a world ​, the distance between city A and city B is 5,625 inches. The two cities are actually 1688 miles apart. On the same ​, what would be the distance between city C and city​ D, two cities that are actually 1296 miles​ apart? Use a proportion to solve this problem.

Answers

Answer:

The distance between C and D is 4.2768 inches.

Step-by-step explanation:

As from A to B the distance is 5.625 inches and actual is 1688 miles

so,

1 mile = 5.625/1688 = 0.0033 inches

So, the distance between C and D is 1296 miles

= 1296 x 0.0033 inches = 4.2768 inches

product of roots=c/a

sum of roots=5+h+1=h+6

product of roots=5(h+1)

so h+6=-(k-1)/1

h+k=1-6

h+k=-5

[tex]t[/tex] = Time in years

Nelson needs 3 and 3/4 cups of flour to make a loaf of bread and 2 and 2/3 cups of flour to make pretzels. How many cups of flour does Nelson need in all?

Answers

Answer:

that is 6 and 5/ 12 cups of flour are required

Step-by-step explanation:

total number of cups required to make a loaf of bread

= 3 + ¾

making their denominators equal and that to 4

= 12/ 4 + 3/ 4

adding numerators

= (12 + 3)/ 4

= 15/ 4

total cups of flour required to make pretzels

= 2 + ⅔

making their denominators equal and that to 3

= 6/ 3 + 2/ 3

adding nunerators

= (6 + 2)/ 3

= 8/ 3

Total cups required:-

= 15/ 4 + 8/ 3

taking lcm of denominators to make the fractions equivalent

= {(15 × 3) + (8 × 4)}/ 12

= {45 + 32}/ 12

= 77/ 12

[tex]6 \frac{5}{ 12} [/tex]

that is 6 and 5/ 12 cups of flour are required.

Answer:

6 5/12 cups.

Step-by-step explanation:

3 3/4 + 2 2/3

= 3 + 2 + 3/4 + 2/3

= 5 + 3/4 + 2/3

The LCM of 4 and 3 is 12 so we have:

5 + 9/12 + 8/12

= 5 + 17/12

= 5 + 1 5/12

= 6 5/12.

Answers

Answer:

Step-by-step explanation:

There are 25 students in Amanda class and 27 in Charley's.

Number of students with no pets in Amanda's = 7 which is 100 * 7/25 = 28%.

In Charley's class this is  8 which is 100 * 8/27 = 29.6%.

Answer:

Charley's class

Step-by-step explanation:

Amanda's class has 7 students with zero pets out of 25 total students. Charley's class has 8 students with zero pets out of 27 total students.

7/25 = 28% with zero pets

8/27 = around 30% with zero pets

Total points needed for two tests to average 90 is 90 x 2 = 180 points.

Which of the following is an example of rigid transformations?
A. Moving the glass from one place to other
B. Cutting a piece of bread
C. Squeezing the cherry
D. All of the choices

Answers

Answer:

Moving the glass from one place to other is rigid transformation.

Step-by-step explanation:

The rigid transformation includes rotation, translation, reflection or their combination.

So, Moving the glass from one place to other place is translation. It is example of rigid transformation.

Now, cutting a piece of bread is not rotation or translation or reflection. So, it is NOT rigid transformation.

Squeezing the cherry is not rotation or translation or reflection. So, it is too NOT rigid transformation.

Relative to such interrogate proposed, the answer is identified as 5520, if quantities ‘a’ and ‘b’ were to subject to define, given such conditions.

Step-by-step explanation:

Understood:

- Such quantity is a four (4) digit number, as explicitly stated.

- The value must be divisible by three (3). Thus, once the digits are summed, such quantity must be able to divide, and distribute evenly, into three (3).

- Likewise, such number is obligated to be divisible by five (5). Thus, the last digit of such quantity must end in either a ‘5’ or a ‘0’.

We were given the mathematical expression: 5a2b

5 + 2 = 7 + x = a number that is divisible by three, as stated in the problem.

X could be a list of differentiated number(s), although for a simplicity, x could be equated to as 5 to produce 12 (which is a factor of three, hence, divisible by three).

Now that ‘a’ has been substituted, ‘b’ must be substituted, similarly:

With ‘b’, we could appoint any number, so long that is either a 5 or 0 in the last digit, hence producing a value divisible my five.

For simplicity, which choosing either 5 or 0 does not make a difference, I will choose zero.

Thus, the rectified answer to such an interrogate is 5520. The difference between the largest of such number and the smallest is their abilities to become divisible by a certain constant ‘a’ and ‘b’.
