A princess hat for a costume is shaped like a cone. The base of the cone is 12 in across and the height is 8
LenaWriter [7]

Answer:

Part a) The drawn in the attached figure

Part b)The slant height of the outside edge is x=10\ in

Step-by-step explanation:

Part a) The drawn in the attached figure

Part b) What is the slant height of the outside edge?

we have that

The diameter of the base of the cone is 12 in

so

r=12/2=6\ in ----> the radius is half the diameter

h=8\ in

Applying the Pythagoras Theorem find the slant height x

x^{2}=r^{2}+h^{2}

substitute the values

x^{2}=6^{2}+8^{2}

x^{2}=100

x=10\ in

Solve the system of equations.
Alborosie

Answer:

y = - 3, x = 6

Step-by-step explanation:

15x + 31y = - 3

x = - y + 3

15(- y + 3) + 31y = - 3

-15y + 45 + 31y = - 3

16y + 45 = - 3

16y = - 48

y = - 3

x = - (- 3) + 3

x = 3 + 3

x = 6

Find the slope please​
scoray [572]

The slope of the line is 2.

The slope is going up from left to right, so it'll be positive to start with. From there you have to do rise over run. That is pretty much how many units up and in towards the slope do you have to go until you find 2 points that are in the center of the line. In this case, the rise over run is 2/1 which equals 2.

May I have brainliest please? :)
