a small bar of gold is a rectangular prism that measures 40 millimeters by 25 millimeters by 2 millimeters. one cubic millimeter

guajiro [1.7K]

Step One
Find the Volume in ccs.

V= l*w*h
l =40 mm
w = 25 mm
h = 2 mm
V = 40*35 * 2
V = 2800 mm^3

Step Two
Find the weight
1 mm^3 = 0.0005
2800 mm^3 = x <<<<< answer 1

$\frac{1}{2800} = \frac{0.0005}{x}$ Cross multiply.

1x = 2800 * 0.0005
x = 1.4 ounces. <<<<< answer 2

If an object is projected upward into the air from ground level, then the height h(t) of the object

AfilCa [17]

Answer:

21.5secs

Step-by-step explanation:

Given the function that models the height of an object as

h(t) = -16t^2+ 344t

The object hit the ground at h(t) = 0

Substitute

0 = -16t^2+ 344t

16t^2 = 344t

16t = 344

t = 344/16

t = 21.5

Hence it takes 21.5secs for the object to hit the ground
