Answer:

second option

Step-by-step explanation:

five times a number: 5n (five times 2 = 5*2 = 10 like that)

four less than five times a number: 5n - 4

its like saying 7 less than 14. You take 7 away from 14 (14-7), not 7-14.

The whole thing equals to 11

Hence: 5n - 4 = 11 and n would equal 3

Answer:

5x - 4 = 11

Step-by-step explanation:

4 less than 5 times a number equals 11

5 times a number minus 4 equals 11

(5*x) - 4 = 11

I hope this helps!!!

How do i evaluate exponantial numbers

vazorg [7]

Answer:

Evaluating Exponents. An exponent is a number that tells how many times the base number is used as a factor. For example, 34 indicates that the base number 3 is used as a factor 4 times. To determine the value of 34, multiply 3*3*3*3 which would give the result 81

Answer:

The answer they want: If you subtract the -2 x from the y side, then you get 4 y= 2 x + 8. Then you divide the entire equation by 4 getting y= 1/2 x + 8. Next, you can either put it in the calculator or you can put the numbers in the equation and solve it.

A cone has a radius of r units and a height of h units. a cylinder has a ridius of 2r units and has the same volume as the cone.

algol [13]

Volume of a cone is calculated as:

$V_{cone}= \frac{1}{3} \pi r^{2} h
$

Volume of the cylinder is calculated as:

$V_{cylinder}= \pi R^{2}H$

The radius of cylinder is twice the radius of cone. So R=2r. The two volumes are given to be equal, so we can write:

$\frac{1}{3} \pi r^{2} h= \pi R^{2} H \\ \\ 
 \frac{1}{3} r^{2} h= (2r)^{2} H \\ \\ 
 \frac{1}{3} r^{2} h= 4r^{2} H \\ \\ 
 \frac{1}{3} h= 4H \\ \\ 
H= \frac{1}{12}h$

Thus, the height of the cylinder will be h/12
