Answer: Pr= 0.03125= 3.125%

Approximately= 3%

Step-by-step explanation:

Probability that 5 out of 10 young adults will be willing to try the new service is.

Pr= Pi ×Pi×Pi×Pi×Pi

Pr= 0.50 ^5

Pr= 0.03125

Pr= 1/32 = 0.03125 =3.125%

Approximately = 3%

a rectangle field has an anrea of 40cm^2. if one side of the field is 3m longer than the other side, find the new area of the fi
oksian1 [2.3K]

The area of the field where the length of each side is increased by 10% is 48.4 cm^{2}.

Step-by-step explanation:

The given is,

               A rectangle field has an area of 40 cm^{2}

               If one side of the field is 3 cm longer than the other side

               The length of new area in each side is increased by 10%

Step:1

          Let,

                          b - One side of rectangle

                          l - Other side of rectangle

          From given.

                         l -  b +3

           Formula for area of rectangle,

                   Area, a = lb      

                          40 = ( b+3) × b

                         40 = b^{2} + 3b

           Solving the above the equation,

                          b = 5 cm

                            l = 8 cm

Step:2

          If the area of rectangle increased by 10%,

                            l = 8 + ( 8 × \frac{10}{100} )

                              = 8.8

                           b = 5 + ( 5 × \frac{10}{100} )

                              = 5.5

         Area of rectangle is,

                      a = ( 8.8 × 5.5 )

                        = 48.4 square centimeters

Result:

        The area of the field where the length of each side is increased by 10% is 48.4 cm^{2}, if a rectangle field has an area of 40 square centimeters and one side of the field is 3 cm longer than the other side.

Help me please !!!!! ASAP !
irga5000 [103]

Answer:

x = 6 sqrt(3)

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2  where a and b are the legs and c is the hypotenuse

6^2+ x^2 = 12^2

36 + x^2 = 144

Subtract 36 from each side

x^2 = 144-36

x^2 =108

Take the square root of each side

sqrt(x^2) = sqrt(108)

x = sqrt(36*3)

x = 6 sqrt(3)
