Answer:
37.5
Step-by-step explanation:
3/8
3 divided by 8= .0375
.0375 times 100= 37.5
Using scale concepts, it is found that the length of her office is of 10 ft, while the width is of 5 ft.
------------------------
- The scale of 6 cm to 15 ft means that each <u>6 cm in the drawing represent 15 ft in actual dimensions</u>.
- From this, a rule of three is applied to find the dimensions.
First, we find the actual length:
6 cm - 15 ft
4 cm - x ft



The actual length is of 10 ft.
Then, we find the actual width:
6 cm - 15 ft
2 cm - x ft



The actual width is of 5 ft.

Given:
The recursive formulae are:
(a) 
(b) 
To find:
The explicit equation.
Solution:
A recursive formula of an arithmetic sequence is
and f(1) is the first term.
Where, d is the common difference.
The explicit formula is

where, a is first term and d is common difference.
(a)
We have,

Here, first term is 8 and common difference is -2. So, the explicit formula is



Therefore, the explicit formula is
.
(b)
We have,

Here, first term is 0 and common difference is 5. So, the explicit formula is


Therefore, the explicit formula is
.
Answer:
12.5π units²
Step-by-step explanation:
Area of a semi-circle = πr²/2
Radius = diameter/2
Radius = 5
Therefore, the area of the semi-circle = 12.5π units²
Answer:
A. 12.6 ft
Step-by-step explanation:
Using sin because of opposite over hypotenuse, you can find x.
sin(52) = x/16
16sin(52) = x
<em>Plug it into your calc.</em>
x = 12.6082
And you have your final answer.
