Answer:
Step-by-step explanation:
<h2>Cone:</h2>
diameter = 12 cm
r = 12 ÷ 2 = 6 cm
h = 6 cm


To find the surface area, we need to find the slant 'l'


= 3.14 * 6 * (6 + 8.49)
= 3.14 * 6 * 14.49
= 273 cm²
Let the amount of shells collected by Aaron be

and the amount of shells collected by Maria be

respectively. Then the following system of equations should be solved:

First of all, express

out of first equation:

Then, replace

in second equation with found expression and solve it:



Finally, replace

in first equation with found value and solve it too:


So, Aaron has found
7 shells while Maria has found
21.
Answer:
19 and 26
Step-by-step explanation:
The other 2 cant work because that would make the total Degrees inside the triangle more than 180 (this is impossible)
Answer:
y = 5x + 3
Step-by-step explanation:
When x = 0 y = 3 so the y-intercept will be 3
And the equation is y = 5x + 3 where the slope is 5
