1=<span>10 ÷ 40
2=</span><span>8.5 s
3=</span><span>141 km
4=</span><span>8.5 h
5=</span>56.0
The equation for perimeter is as following...
Perimeter = ∑ side lengths (sum)
26 = 12 + x + x - 4
∴ our answer is <span>x + x - 4 + 12 = 26</span>
10. 4,200 cm
This is the correct answer!
Answer:
What is the question?
Step-by-step explanation:
Answer: About 8.4 mm
Step-by-step explanation:
Since this is a right triangle, we will solve using the Pythagorean theorem. In the equation we are solving for <em>c</em>, the hypotenuse, with 3.7 mm and 7.5 mm being <em>a</em> and <em>b</em>, the legs.
a² + b² = c²
(3.7)² + (7.5)² = c²
13.69 + 56.25 = c²
69.94 = c²
= c
8.363 mm ≈ c
c ≈ 8.4 mm, when rounded to the nearth tenth of a millimeter
The missing side length is about 8.4 mm.
