Answer: 12 cm

Step-by-step explanation:

The masses of the spheres are proportional to their volums, and the cube of the ratio is k^3=135/5=27 ==> k=3

The greater radius is 3*4=12 (cm)

Three consecutive numbers are such that when they are taken in increasing order and multiplied by 2,3and 4 respectively, they ad
Ivenika [448]

Answer:

7 , 8 , 9

Step-by-step explanation:

Assume three consecutive number are,

x , (x+1) , (x+2)

Multiplied by 2 ,3 and 4 respectively

2x , 3(x + 1) , 4(x + 2)

Sum of all = 74

So,

2x + 3(x + 1) + 4(x + 2) = 74

2x + 3x + 3 + 4x + 8 = 74

9x + 11 = 74

9x = 63

x = 7

So,

x , (x+1) , (x+2)

7 , (7+1) , (7+2)

7 , 8 , 9

A segment has one endpoint at (-4,1) and it's midpoint at (3,0). What is the x-coordinate of the other endpoint?
nikklg [1K]

Answer:

(10; -1)

the x-coordinate of the other endpoint is (x;y)

because the segment has midpoint at (3;0)

=> x - 4 = 3.2 = 6

y + 1 = 0.2 = 0

<=> x = 10

y = -1

=> the other endpoint is (10; -1)
