General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
Step-by-step explanation:
<u>Step 1: Define</u>
h(r) = (2/3)r - 6
h(-9) is r = -9
<u>Step 2: Evaluate</u>
- Substitute: h(-9) = (2/3)(-9) - 6
- Multiply: h(-9) = -6 - 6
- Subtract: h(-9) = -12
And we have our answer!
0.861
the one at the end is rounded down... making the decimal 0.86
Making it 86%
The total cost would be $9.45
Answer:
Simply count 4 × 6 =28
Step-by-step explanation:
Given:
The diameter of the circle = 14 cm
To find:
The area of the circle.
Solution:
We have,
Diameter of the circle = 14 cm
We know that the radius of the circle is half of its diameter. So,


The area of a circle is:

Substituting
in the above formula, we get



Therefore, the area of the circle is 154 square cm.
