Answer:

Radius is 2.18

Step-by-step explanation:

We  have been given the surface area of sphere 60 square feet

And formula for area of sphere is 4{\pi}r^2

using {\pi}=3.14

On substituting the values 60=4\cdot 3.14\cdot r^2 we get:

60=4\cdot 3.14\cdot r^2

On simplification we get:

4.77= r^2

\sqrt{4.77}= r

2.18= r

Answer:

23.44%

Step-by-step explanation:

The probability of getting a 4 on the first 2 throws and different numbers on the last 5 throws = 1/6 * 1/6 * (5/6)^5

= 0.01116

There are 7C2 ways of the  2 4's  being in different positions

= 7*6 / 2 = 21 ways.

So the required probability =  0.01116 * 21

= 0.2344 or 23.44%.

What is the value of x?
skelet666 [1.2K]

Answer:

x = 20

Step-by-step explanation:

Since ΔACB ≅ ΔDCE then ∠A ≅ ∠D, that is

3x - 10 = 2x + 10 ( subtract 2x from both sides )

x - 10 = 10 ( add 10 to both sides )

x = 20

Answer:

16

Step-by-step explanation:

Each could be watched in the places of 1,2,3 or 4. So each movie has 4 places it could be. Since you rented 4 movies you would do 4x4 which equals 16.

Find x so that b ll e??????
tekilochka [14]

x=6


(6x+4) = (8x-8)


∠3 and ∠6 have to be equal since they are opposite interior angles (these angles are always equal to each other). Opposite interior angles prove that two lines are parallel if they are equal, so you just set them equal to each other and solve for x.


(6x+4) = (8x-8)

-6x -6x

4 = (2x-8)

+8 +8

12 = 2x

/2 /2

6 = x


CHECK

(6x+4) = (8x-8)

(6[6]+4) = (8[6]-8)

(36+4) = (48-8)

40 = 40
