The volume of the cube is given by:
V=a³
where a is the side length
thus, given that:
a=4 inches
then
V=4³=64 in³
Answer: 64 in³
Perimeter of the triangle is 30.75 inches.
Step-by-step explanation:
- Step 1: Given sides of the triangle = 11.25 in, 9.25 in, 10.25 in
- Step 2: Formula for perimeter of triangle = length of sides of the triangle
- Step 3: Substitute in the formula
Perimeter = 11.25 + 9.25 + 10.25
= 30.75 inches
Note that
10² = 100
0.08² = 0.0064
and
101.6064 = 100 + 1.6 + 0.0064
It also happens that
1.6 = 2 • 10 • 0.08
which means
101.6064 = 100 + 1.6 + 0.0064
101.6064 = 10² + 2 • 10 • 0.08 + 0.08²
101.6064 = (10 + 0.08)²
101.6064 = 10.08²
which means
√101.6064 = 10.08
which, to one decimal place, is approximately 10.1.
Let as consider, we need to find the fixed fee.
Given:
Cost of each ticket = $18
Number of tickets = 5
Total cost = $93
To find:
The fixed fee.
Solution:
Let x be the fixed fee..
Cost of 1 ticket = $18
Cost of 5 ticket = $(5 × 18)
= $90
Total cost 5 tickets = Fixed fee + Cost of 5 tickets
Therefore, the fixed fee is $3.
