- 6 \frac{1}{4}  - ( - 2 \frac{1}{8} )

=  - 6 \frac{1}{4}  + 2 \frac{1}{8}

=   \frac{ - 25}{4}  +  \frac{17}{8}

=   \frac{  - 50}{8}  +  \frac{17}{8}

= \frac{ - 50 + 17}{8}

=  \frac{ - 33}{8}

=  - 4 \frac{1}{8}

Use the scale factor 1:12 to find the missing dimension. Great white shark actually lengthy 21ft
hammer [34]

Answer:

m = 21 inches

The model length is 21 inches

Question;

Use the scale factor 1:12 to find the missing dimension. Great white shark actually lengthy 21ft. Find the model length in inches.

Step-by-step explanation:

Given;

Scale factor = 1:12

Actual length a = 21 ft

Let m represent the model length;

The ratio of model length to actually length is given as;

m/a = 1/12

m = a/12

Substituting a=21 ft;

m = 21/12 ft

Converting to inches;

1 ft = 12 inches

So,

m = 21/12 ft × 12 inches/ft

m = 21 inches

The model length is 21 inches

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
levacccp [35]

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

99

\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.
