Determine the solution to the system of equations:
Morgarella [4.7K]
  x - 3y = 1   ⇒ 3x - 9y = 3
3x - 5y = 11 ⇒ 3x + 5y = 11
                             -14y = -8
                              -14    -14
                                   y = ⁴/₇
                            x - 3y = 1
                           ⁴/₇ - 3y = 1
                         - ⁴/₇        - ⁴/₇
                                -3y = ³/₇
                                 -3     -3
                                   y = ⁻¹/₇
                             (x, y) = (⁴/₇, ⁻¹/₇)

I'm really bad at geometry. Please help
postnew [5]
The sides of the frame are (12+2x) and (6+2x).
Its area A is 112.

Therefore by equating:
(12+2x)*(6+2x)=112
you can get the answer for x. You will obtain a quadratic equation you have to solve.

Choose the two rectangular prisms that have a volume of 36cm^3?
oee [108]

Answer:

<em>Correct choices: B, D</em>

Step-by-step explanation:

<u>The Volume of a Rectangular Prism</u>

Given a rectangular prism of dimension W, L, and H, the volume is calculated as:

V = WLH

Each small cube of the figure has a volume of 1 cube centimeter. We need to calculate the volume of each solid and determine which ones have a volume of 36 cube cm.

A: V = 5*3*4 = 60 cube cm

B: V = 3*3*4 = 36 cube cm

C: V = 3*4*2 = 24 cube cm

D: V = 6*2*3 = 36 cube cm

E: V = 2*4*2 = 16 cube cm

Correct choices: B, D

Use trigonometry

<u>Let the height of the cloud be x, then we have:</u>

  • tan 35° = x/525
  • x = 525 tan 35°
  • x = 367.6 (rounded)

The height of the cloud layer is 367.6 m
