Answer:
a. 12.8 cm b. 3.125
Step-by-step explanation:
To find any scale drawing use a proportion with one unit of values on the top and the other on the bottom. For example 8cm/5km = x/8km. So you would multiply 8 cm and 8 km and then divide by 5 to get 12.8 cm. For the second question plug in 5m in the numerator and solve for its denominator.

Answer:
= 5n - 1
Step-by-step explanation:
There is a common difference between consecutive terms , that is
9 - 4 = 14 - 9 = 19 - 14 = 5
This indicates the sequence is arithmetic with nth term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 4 and d = 5 , then
= 4 + 5(n - 1) = 4 + 5n - 5 = 5n - 1
An ordinary piece of copier paper has a dimension of 8.5
inches by 11 inches. Converting inches to feet:
8.5 in * (1 ft / 12 in) = 0.708 ft
11 in * (1 ft / 12 in) = 0.917 ft
Therefore the area is simply:
Area = 0.708 ft * 0.917 ft
<span>Area = 0.65 ft^2</span>
