Step-by-step explanation:
We have the closed circle on -6 and the ray drawn to the right (to the infinity).
Describe this set of real numbers in words:
All numbers not less than -6.
Describe this set of real numbers in set notation.
x ∈ [-6, ∞)
Write an equation or an inequality that has the set above as its solution set.
x ≥ -6

Answer:
Step-by-step explanation:
<h2>
1) </h2>
scale is 1 inch=9 feet
4 inches*9= 36 feet
10 inches*9=90feet
<em><u>it is 36 feet by 90 feet</u></em>
<h2><em><u>
2)</u></em></h2>
scale is 1 inch=5 feet
4 inches*5=20 feet
<em><u>it is 20 feet</u></em>
<h2>
3)</h2>
scale is 1:12
14 inches*12=168
it is 168
Answer:
204 cm
Step-by-step explanation:
Triangle area = base × height ÷ 2
6×4÷2=12
Rectangle area = side 1 × side 2
6×10=60
5×10=50
There are 2 triangles, so make 12×2=24, 24 is the surface area of the triangles.
There are 2 rectangles with 5 in one side, so make 50×2=100 of area of this 2 rectangles
Now just sum the areas:
100+24+60= 204
