Answer:
-22 ≤ temperature(F) ≤ 266
Step-by-step explanation:
Given that,
The label on the car's antifreeze container claims to protect the car between -30C and 130C.
Formula to convert Celsius temperature to Fahrenheit
<h3>C = 5/9 (F - 32)</h3><h3>9C/5 = (F - 32)</h3><h3>9C/5 + 32 = F</h3><h2>F = 9C/5 + 32 </h2><h3>1)</h3>
-30C = ?F
F =9(-30)/5 + 32
F = -22
<h3>2)</h3>
130C = ?F
F =9(130)/5 + 32
F = 266
The inequality to determine the Fahrenheit temperature range at which this antifreeze protects the car is
<h3>-22 ≤
temperature(F) ≤ 266</h3>

Answer:
22.4
Step-by-step explanation:
using altitude theorem, the height of the triangle is 20
let y = height
10/y = y/40
y² = 400
y = 
or 20
Now we can us the Pythagorean Theorem to find 'x':
10² + 20² = x²
100 + 400 = x²
x=
≈ 22.4

Answer:
20.28 cm²
Step-by-step explanation:
The rectangle on the bottom is 7 cm by 2 cm.
The semicircle has a diameter of 7 cm - 1 cm - 2 cm = 4 cm
diameter = 4 cm
radius = diameter/2 = 2 cm
total area = area of semicircle + area of rectangle
total area = (1/2)πr² + LW
total area = (1/2)(3.14)(2 cm)(2 cm) + 7 cm × 2 cm
total area = 20.28 cm²
