Answer:75%
Step-by-step explanation:
You know that the ratio of the television's screen is . This ratio can be also written as the following fraction:
The television shows an image with a ratio of which can be also written as a fraction:
Set up the following proportion and solve for "x":
Now, in order to find the percent of the screen area occupied make the following division:
Step-by-step explanation:
16/80 = 1/5 just put it into the calculator
Answer:
Both plans would cost $100 if 6 gigabytes of data are used.
Explanation:
From the question, the system of equation are correctly represented by using small letter c to represent the total cost in dollars for both equations as already assumed in the question as follows:
c = 52 + 8d ........................... (1)
c = 82 + 3d ........................... (2)
Since c is common to both, equations (1) and (2) can therefore be equated and d solved for as follows:
52 + 8d = 82 + 3d
8d - 3d = 82 - 52
5d = 30
d = 30 / 5
d = 6
Substituting d = 6 into equation (1), we have:
c = 52 + (8 * 6)
c = 52 + 48
c = 100
Since d = 6 and c = 100, it therefore implies that both plans would cost $100 if 6 gigabytes of data are used.
First let us convert 0.01 into fraction:

Now we convert 100 and 4 into perfect squares as follows:

Now we use the property of :


So ten tens = 100 so u multiply and u get 40 tens which are 400= 4 hundreds
