dexar [7]

Answer:

Step-by-step explanation:

Alright, lets get started.

There are approximately $3.2 \times 10^7$ mosquitoes near each backyard pool.

The city has total number of pools $6.7 \times 10^{12}$ .

So the total mosquitoes will be : $3.2 \times10^7 \times6.7\times 10^{12}$

So the total mosquitoes will be : $21.44 \times 10^{19}$

So the total mosquitoes will be : $2.144 \times 10^{20}$ : Answer

Hope it will help :)

a) How many significant figures are in the numbers 99 and 100? (b) If the uncertainty in each number is 1, what is the percent u

Answer:

2, 3

1.01, 1

Percentage uncertainty

Step-by-step explanation:

a) The significant figures in the number 99 is 2

The significant figures in the number 100 is 3

b) Uncertainty in each of the numbers for both the numbers is 1

Percentage uncertainty

$\text{Percentage uncertainty}=\frac{\text{Uncertainty}}{Value}\times 100 \\\Rightarrow \text{Percentage uncertainty}=\frac{1}{99}\times 100=1.01$

Percentage uncertainty = 1.01

100

$\text{Percentage uncertainty}=\frac{\text{Uncertainty}}{Value}\times 100 \\\Rightarrow \text{Percentage uncertainty}=\frac{1}{100}\times 100=1$

Percentage uncertainty = 1

c) Percentage uncertainty is a better way to express the numbers as the significant figures do not show the actual value of the numbers.

43 tens × 3 tens = how many hundreds

ladessa [460]

43 tens = 43 * 10 = 430
3 tens = 3 * 10 = 30

430 x 30 = 12900 tens
12900/100 = 129 hundreds <===
