So to find the speed we find the unit rate
to do that we do (y2-y1)/(x2-x1)

so we can use any points, but I'm going to use points (0,25) and (1,75)

75-25=50
2-1=1
then we do rise(y) over run(x)
50/1=50

so the boat is going 50mph making your answer. D

50 mph y=50x+25 where x is hours traveled and y is total distance

Step-by-step explanation:

<h2>Cone:</h2>

diameter = 12 cm

r = 12 ÷ 2 = 6 cm

h = 6 cm

$\sf \boxed{\text{\bf Volume of cone = $\dfrac{1}{3} \pi r^2h$ }}$

$\sf = \dfrac{1}{3}*3.14*6*6*6\\\\ = 226.08 \ cm^3$

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

$\sf l = \sqrt{h^2+r^2}\\\\ =\sqrt{6^2+6^2}\\\\ = \sqrt{36+36}\\\\ =\sqrt{72}\\\\= 8.49 \ cm$

$\sf \boxed{\text{\bf Total surface area of cone = $\pi r(r+l)$}}$

= 3.14 * 6 * (6 + 8.49)

= 3.14 * 6 * 14.49

= 273 cm²

Half the difference of a number and 16 is negative 2

Answer:

20

Step-by-step explanation:

Work backwards. If -2 x 2= -4 then something plus negative four will equal 16, which is 20.

Which of the following represents the formula that could be used to find the height of the cone

podryga [215]

If you know the volume then:
(3 * Cone Volume) / (PI * radius^2) = height
