Answer:
The equation is .
Step-by-step explanation:
Given:
Initial Charge = $3
Total Cost = $6
Number of minutes used = 5 minutes
Let the additional charge applied per minute be 'x'.
Solution:
Now we can say that;
Total cost to use Computer will be equal to Initial Charge plus additional charge applied per minute multiplied by number of minutes.
framing in equation form we get;
Now Subtracting both side by 3 using subtraction property of equality we get;
Now Dividing both side by 5 using Division property of equality we get;
Hence Additional charge is $0.6.
Now we need to write the equation for the C(t).
Where C(t) ⇒ Total cost using computer
t ⇒ time in minutes at the cafe
Now we know that;
Total cost to use Computer will be equal to Initial Charge plus additional charge applied per minute multiplied by number of minutes.
So with data given equation can be framed as;
Hence, The equation is .
Answer:
Step-by-step explanation:
25
-13
which equals 12
This is because the circles have areas of 9
and 4
respectively.
Plus we can tell the square has the area of 100 due to the fact that the diameters of the circles add up to 10, meaning the larger circle has a radius equal to 5 and an area of 25
. Subtract the other two from the larger one and you get your answer.
Answer:
A- they both are scaled copies 1 is 2x smaller than the other
40:80
375:750
Step-by-step explanation:
15 x 2 = 30
25x2 = 50
You are welcome:)
