Weight is 1.7 × 10^5 kg
Step-by-step explanation:
- Step 1: Given that the weight of the blue whale = 170 tonnes
- Step 2: Convert the number of tonnes into kg.
⇒ 170 tonnes = 170 × 1000 (1 tonne = 1000 kg)
⇒ 170 tonnes = 17 × 10^4 kg
- Step 3: Convert it into standard format, that is with just one decimal point.
⇒ 17 × 10^4 = 1.7 × 10^5 kg (Dividing and multiplying by 10 on both sides)
We have to find the width first.
72 divide by 9 = 8
To find the perimeter, you can do it two ways:
1. 9 + 8 + 9 + 8 = 34
2. 2(9) + 2(8) = 18 + 16 = 34
The answer is 34 feet.
Answer:
$7,359.65
Step-by-step explanation:
The computation of the amount that to be deposited is shown below:
Here we have to calculate the present value
As we know that
Present value = future value ÷(1+ rate of interest)^years
where,
rate of interest = 12.2% ÷ 4 = 3.05%
And, the years is = 5 × 4 = 20
Now the present value is
= $13,422 ÷ (1+ 3.05%)^20
= $7,359.65
