In converting a decimal to a percent you just need to multiply it by 100.
Solution on the problem above:
3.45 x 100 = 345%
Therefore the answer is letter A.
It will be vice versa in converting percent to decimal. You just need to divide it by 100.
For example, we convert the 345% to decimal:
345%/100 = 3.45
A = pi x r^2
it gives you the diameter.
half of the diameter is the radius
therefore, A = pi x 14^2
Cot=cos/son
Cot(a)=cos(a) / sin(a)
Cos(a)=5
Sin(a)=12
2sina-3cosa / 4sina-9cosa
2(12)-3(5) / 4(12)-9(5)
24-15 / 48-45
9/3
3
The answer will be a(8b + 7c)
Answer:
12 months
Step-by-step explanation:
Set up a formula; 75 + 15x = 255
Now, solve for x, which is number of months.
subtract 75 from both sides.
15x = 180
divide both sides by 15.
x = 12
x is equal to 12 - she would have had to have the subscription for 12 months to spend 255$.
