Answer:

Surface area of the cone = 360π in²

Step-by-step explanation:

Formula for the surface area of a cone is,

Surface area = πr(r + l)

Here 'r' = radius of the circular base of the cone

l = Lateral height of the cone

Now we substitute the values in the formula from the figure attached,

Surface area = π(10)(10 + 26)

                     = 360π in²

Therefore, surface area of the cone will be 360π in².

balandron [24]

Step-by-step explanation:

The equation equation looks incomplete. However assuming it to be 212÷34.

This becomes a simple case of division. Now forming a world problem on this equation.

Consider there are 212 chocolates to be distributed among 34 children, such that each child gets equal number of chocolates. Find how many chocolate does each child got.

Simply divide 212 by 34 to get the answer =212/34

Suppose that the functions g and f are defined as follows.
Sholpan [36]

Answer:

Following are the solution to the given question:

Step-by-step explanation:

Given:

\to g(x)= -3+2x^2 \\\\\to f(x)=9-6x

Calculating the value of (\frac{g}{f})(2):

\to (\frac{g}{f}) (2)= (\frac{g(x)}{f(x)}) \times  (2)

               =\frac{2x^2-3}{9-6x} \times 2\\\\=\frac{2\cdot 2^2-3}{3(3-2\cdot 2)} \\\\=\frac{2\cdot 4-3}{3(-1)}\\\\ =\frac{8-3}{-3}\\\\  =\frac{5}{-3}\\\\  = - \frac{5}{3}\\\\

x=- \frac{\sqrt{3}}{2} and x=\frac{\sqrt{3}}{2} are not in the domain.

Domain: x \belong (- \infty, -\frac{\sqrt{3}}{2})\cup (- \frac{\sqrt{3}}{2},  \frac{\sqrt{3}}{2} )\cup (\frac{\sqrt{3}}{2}, \infty)

Please help! Will give brainliest for right answer!
KIM [24]
The slope of the line, is the one with an variable, in this case x. The other value, 27.52, is the y intercept, which would represent how much money he began with. So the variable 17.63x represents how much he could expect to make per week. We know it is per week because there is only a single x, if there were two x's it would be per 2 weeks, three x's per 3 weeks and so on.

From this we can conclude the answer is B, Aidan can expect to save about $17.63 each week
