A rhombus is a 4 sided shape with equal lengths. Even though it has equal lengths, it has opposite sides that are parallel, and angles that are equal. It also has diaginols (dashed lines) meat in the middle
You have to look up how many miles are in one km.
You need that number to solve this problem.
<u> 1 km = about 0.62137... mile</u> (rounded)
160 km = (160) x (0.62137) = <em>99.419 miles</em> (rounded)
Answer:
6cm
The dimensions are 6cm x 6cm x 6cm
Step-by-step explanation:
Surface area of a cube = 6a²
where a = edge
but because this cube isn't covered, the sides would by 5 and not 6
5a² = 180cm²
divide both sides by 5
a² = 36cm²
Find the square root of each side
a = 6cm
The dimensions are 6cm x 6cm x 6cm
width (w): w
Length (L): 4w + 9.7
Perimeter = 2L + 2w
91.4 = 2(4w + 9.7) + 2(w)
91.4 = 8w + 19.4 + 2w
91.4 = 10w + 19.4
72.0 = 10w
7.20 = w
Length (L): 4w + 9.7 = 4(7.2) + 9.7 = 28.8 + 9.7 = 38.5
Answer: width = 7.2 cm, Length = 38.5 cm
