The amount of money by which Denny went over is $45
By how many gigabytes did the family exceed their data usage?
The initial plan was for 20 gigabytes, eventually, the family used 24.5 gigabytes in the month, which means the excess amount of data used can be determined thus:
excess data usage=24.5 gigabytes-20 gigabytes
excess data usage=4.5 gigabytes
For each extra gigabyte of data, the family needs to pay $10, which means that the amount of money Denny owes is 4.5 gigabytes multiplied by $10
The amount that he went over=$10*4.5
the amount that he went over=$45

Answer:
18 square units
Step-by-step explanation:
To find the area of a rectangle, we just need the length and height.
3 vertices of a rectangle are given, which is enough here to figure out the length (x-axis distance) and the height (y-axis distance).
From (0,0) origin to (3,0) would be 3 - 0 = 3 units in the x-axis. That is length:
Length = 3 units
Now, a point is given (0,6), that is in the y-axis. This is from origin. So, the height is:
6 - 0 = 6 units
Height = 6
Now, the area would be:
Area = Length * Height
Area = 3 * 6
Area = 18 square units
Step-by-step explanation:
1 - ((9*t) - (9*-2) = ( 4*t) - (4*-15)
1 - 9t + 18 = 4t + 60
- 9t - 4t = 60 - 1 - 18
-13t = 40
t = 40/-13
Yes they do because 12/6 go into 2/1
Ni : Zn: Cu = 7:2:9 =7x : 2x : 9x
7x+2x+9x = 3.8
18x=3.8
x=3.8/18=1.9/9≈0.21
Ni: 7x=7*0.21=1.47 ≈1.5 kg
Zn: 2x=2*0.21=0.42≈0.4 kg
Cu: 9x=9*0.21=1.89 ≈1.9 kg
Check 1.5+0.4+1.9 =3.8 True
