Keenan wants to make a paperweight at pottery class. He designs a pyramid-like model with a base area of 808080 square centimeters and a height of 7.57.57, point, 5 centimeters. The density of the clay he is using is 1.71.71, point, 7 grams per cubic centimeter.
What is the weight of Keenan's paperweight?

340

Step-by-step explanation:

The volume of the pyramid-like paperweight is 1/3 * 80 * 7.5= 200

Now we can plug density=1.7, total quantity=w and volume=200 in the equation.

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
