15x + 4 for x = -1.5 1

-18.5

Step-by-step explanation:

15x +4

Let x = -1.5

15(-1.5) +4

-22.5 +4

-18.5

-18.65

Step-by-step explanation: Here, we have the expression 15x + 4 and we want to evaluate the expression when x = -1.51.

To evaluate an expression, we simply plug the value of the variable into the expression and solve.

So here, since x is equal to -1.51, we have 15(-1.51) + 4.

15(-1.51) is equal to -22.65.

So we have -22.65 + 4 which is equal to -18.65.

So the value of our expression when x is equal to -1.51 is -18.65.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
