Answer:7/4= 1.75 and 3/8=0.375
Step-by-step explanation:
5/9= 0.555555.......
3/8=0.375
2/3=0.666666......
That's a translation, a slide with no rotation or scaling to make ABC into A'B'C'.
Answer: D. None of the above
The answer is B. 12+1.5( n-1). let's say n is 2. it would be 12+1.5(2-1) which is 12+1.5 which is 13.50... which is the cost of 2 toppings
For this case we have that the temperature drops steadily at a speed of
, that is, every hour drops 0.8 degrees. So, we can propose a rule of three:
1 hour ----------> 0.8 degrees
x ------------------> 4.4 degrees
Where the variable "x" represents the number of hours that must pass for the temperature to decrease by 4.4 degrees.
![x = \frac {4.4 * 1} {0.8}\\x = 5.5](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%20%7B4.4%20%2A%201%7D%20%7B0.8%7D%5C%5Cx%20%3D%205.5)
Thus, for the temperature to decrease by 4.4 degrees, 5.5 hours must pass.
Answer:
5.5 hours
45 minutes * 6 days = 270 minutes at the gum
but we need to change minutes to hours
1 hours = 60 minutes
270 minutes * 1 hr/60 minutes =
270/60 hours
divide top and bottom by 10
27/6
divide top and bottom by 3
9/2
4.5 hours
