Answer 1

Answer: To find the surface are, we can add up the area of all of the sides.

Top:
4in x 9in = 36in^2

Bottom:
4in x 9in = 36in^2

Front:
5in x 9 in = 45in^2

Back:
5in x 9 in = 45in^2

Right:
4in x 5in = 20in^2

Left:
4in x 5in = 20in^2

Adding them all together:
36+36+45+45+20+20 = 202in^2

The surface area of the prism is 1. 202 in^2

Determine the mechanical energy of this object: a 1-kg pendulum has a speed of 2 m/s at a height of 1 meter.

Answers

I am going to help you using physics......

Mechanical Energy = Potential Energy + Kinetic energy (or vice versa)

ME = PE + KE

PE = mgh ( m= mass; g = gravity constant which is 9.81; h = height)
= (1kg)(9.81)(1m)
PE = 9.81

KE = 1/2mv^2 (m = mass)(v = velocity)
= 1/2(1 kg)(2 m/s^2)
= (1/2)(4)
KE = 2

ME = KE + PE
ME = 9.81 + 2
ME = 11.81

hope this helps :)

What is, 18 5/12+8 10/17+23 7/12+28 7/17

Answers

18 5/12 + 8 10/17 + 23 7/12 + 28 7/17

First change them to improper fractions

18 5/12 = 221/12

8 10/17 = 146/17

23 7/12 = 283/12

28 7/17 = 483/17

now find the common denominator which would be 204

221/12 = 3757 /204

146/17 = 1752 /204

283/ 12 = 4811 /204

483/ 17 = 5796 /204

now add

(3757 + 1752 + 4811 + 5796) = 16,116/204

now divide

16,116 ÷ 204 = 79

Your answer is D. 79

Hope this helps. :)
