What is the radius of a sphere which area is equal to the sum of the areas of four circles of radius 7?
antiseptic1488 [7]

Answer:

radius = 7 units

Step-by-step explanation:

Given:

Radius = 7 units

Find area of 4 circles:

1 circle = π (7)² = 49π units²

4 circles = 49π x 4 = 196π units²

Find radius of sphere:

4πr²  = 196π

r² = 49

r = 7

Prove the equation (2x+5)2 = 4x (x + 5) +25
shtirl [24]

Answer:  x = -5/2 and x = -3/2

Step-by-step explanation:

(2x + 5)2 = 4x (x + 5) +25

   4x + 10 = 4x² + 20x + 25

   [minus 4x on both sides.]

            10 = 4x² + 16x + 25

   [minus 10 on both sides.]

            0 = 4x² + 16x + 15

ac = 4(15) = 60,then find the factors that add up to 16, which is 6 and 10.

            0 = 4x² + 6x + 10x + 15

            0 = 2x(2x + 3) + 5(2x + 3)

            0 = (2x + 5)(2x + 3)

2x + 5 = 0                                 2x + 3 = 0

       2x = -5                                    2x = -3

         x = -5/2                                    x = -3/2

Assume that two marbles are drawn without replacement from a box with 1 blue, 3 white, 2 green, and 2 red marbles. Find the prob
tatuchka [14]

Answer:

second marble is blue and  first marble is white is  \frac{1}{7}

Step-by-step explanation:

given data

two marbles

box = 1 blue, 3 white, 2 green, and 2 red marbles

                                                                           

solution

we get here second marble is blue and given that the first marble is white

= P(3c1 × 1c1) ÷ P(3c1 × 7c1)          ................................................1

= 1c1 ÷ 7c1

= 1 ÷ 7

so second marble is blue and  first marble is white is  \frac{1}{7}

luda_lava [24]

Answer:

(5, -2)

Step-by-step explanation:

Use substitution

Y=5x-27 Put this equation into the place of y in the second one.

2x+3y=4

2x + 3(5x - 27) = 4     then solve for x

2x + 15x - 81 = 4

17x - 81 = 4

17x = 85

x = 5

Then put the value of x back into one of the equations and solve for y

y = 5(5) - 27

y = 25 - 27

y = -2
