Answer:
Step-by-step explanation:
When you multiply two terms with same base, add the exponents.
Example: x*x² = x* x*x = x³
In short, x*x² = x¹⁺² = x³
So first, find the area of the square. 12x12= 144inches^2
Then find the area of the circle. To do this we use pi x r^2. The radius of the circle is 6 inches. Pi x 6^2 = 113.04inches^2.
144 - 113.04 = 30.6, so your answer is 30.6 inches^2
The circles circumference is worked out by using pi x d. The diameter is 12 inches, so 3.14x12 = 37.68 inches.
The squares perimeter is 12 x 4 = 48 inches.
If you round up the circumference of the circle to the nearest integer, you get 38 inches. The ratio would therefore be, 38:48, which can be rounded down to 19:24 :)
Answer:
75
Step-by-step explanation:
let the number of texts equal T
total amount charged by talk company - 15 + 0.1T
total amount charged by mobile service = 0.3T
we are to find the number of texts that would make the charges equal
15 + 0.1T = 0.3T
Collect like terms
15 = 0.3T - 0.1T
15 = 0.2T
T = 15/0.2 = 75
Answer:
answer = 100 X100 - 25 X 25 = x
10000 - 625 = x
