Answer:

The sum of the first 10 positive even numbers is 10\times 11=110

Step-by-step explanation:

From the table, we see that,

Sum of the numbers 2+4+6+8+10=30=5\times 6=5(5+1)

That is, when there are 5 terms in the sequence, the sum is given by 5\times 6.

Then, in general, when there are 'n' terms in the sequence, the sum is given by n(n+1)

We are required to find the sum of 10 even terms.

Therefore, when there are 10 terms in the sequence, the sum will be 10(10+1)=10\times 11

<h3>Hence, the sum of the first 10 positive even numbers is 10\times 11=110</h3>

The diameter of a cone is X cm the height is 18 cm mThe The height is 18 cm and the volume is 301.44 cm what is x
HACTEHA [7]
The volume of a cone is V=(1/3)(area of the base)(height)= (1/3)(pi*r^2)(h)
r^2= (d/2)^2 = (d^2)/4. Given: V= 301.44cm^3 and h= 18cm.
r^2= V/[(1/3)(pi)(h)]
r^2= 3V/(pi)(h)
(d^2)/4= 3(301.44)/(3.14)(18)
d^2= 12(301.44)/(3.14)(18)
d^2= 63.967
d= 7.997
d~= 8cm.

A ton is equivalent to 1000 pounds so:
the elephant weighs 5000 pounds
5000-570= 4430
The elephants weighs 4430 pounds more.
