Answer:
$64,269.65
Step-by-step explanation:
Lets use the compound interest formula provided to solve this:
<em>P = initial balance</em>
<em>r = interest rate (decimal)</em>
<em>n = number of times compounded annually</em>
<em>t = time</em>
<em />
First, change 6.25% into a decimal:
6.25% -> -> 0.0625
Since the interest is compounded quarterly, we will use 4 for n. Lets plug in the values now:
The value of Sara's investment after 30 years will be $64,269.65
It's a 1x2x3 box, aka parallelepiped. So we have 2 1x2 faces, 2 2x3 faces and 2 1x3 faces. We add them up:
A = 2(1 × 2 + 2 × 3 + 1 × 3) = 2(2+6+3) = 22
Answer: d. 22
Answer:
Cost of 20 boxes = RS. 188
Step-by-step explanation:
Given:
Length of box = 30 cm = 0.3m
Width of box = 40 cm = 0.4 m
Height of box = 50 cm = 0.5 m
Cost per m² = Rs. 10
Find:
Cost of 20 boxes
computation:
TSA of box = 2[lb + bh + hl]
TSA of box = 2[(0.3)(0.4) + (0.4)(0.5) + (0.5)(0.3)]
TSA of box = 2[0.12 + 0.2 + 0.15]
TSA of box = 0.94 m²
Cost of 20 boxes = 0.94 x 20 x 10
Cost of 20 boxes = RS. 188
