1. Equation #1: <span>g+s=150
Equation #2: </span><span>8g +5s = 900
2. Solution to the system:
</span>G = 150 – s
<span>8(150-s)+5s=900 </span>
<span>1200-8s+5s=900 </span>
<span>-900 -900 </span>
<span>300/3-3s/3
</span>
3. Idk about this one...
Answer: the height of the building is 40ft
Step-by-step explanation:
Looking at the right angle triangle formed,
With angle P as the reference angle, the length shadow of the building on ground represents the adjacent side of the right angle triangle.
The height of the building represents the opposite side of the right angle triangle.
a) to determine the height of the building, x, we would apply the tangent trigonometric ratio which is expressed as
Tan θ, = opposite side/adjacent side. Therefore, the equation becomes
Tan P = x/50
b) 0.8 = x/50
x = 50 × 0.8
x = 40 ft
The answer is y to the power of negative 1, I think. Because -4+3 is -1.

Answer:
C) Both reflection and translation
Step-by-step explanation:
An isometry of the plane is a linear transformation which preserves length. Isometrics includes rotation, translation , reflection ,glides and the identity map.
A geometry transformation is either rigid or non-rigid
The another name for a rigid transformation is 'isometry'.
The dilation is not isometry
