Answer:
20 degrees
Step-by-step explanation:
First, draw the triangle and label the sides and angles. (See the picture attached)
The red lines on sides FG and HF indicate that the sides are congruent since this is an isosceles triangle. Isosceles triangles have two congruent sides and angles.
All angles add up to 180 degrees. You were already given 140 for angle F. So, use to find angle h, subtract 140 from 180 and divide by 2.
180 - 140 = 40
40 / 2 = 20
Angle h is 20 degrees

To find percentage decrease, we need to see how "much" of 120 was taken off.
So, let's call the percentage x (the percentage in decimal form).
120 * x = 78
so,
78/120 = x
.65 = x
So, our percentage in decimal form is .65, to get it to an actual percentage, we multiply it by 100 (since a percentage is out of 100)
The percentage decrease is 65%
The tablet has a capacity of 22GB
one bite = 1 character
2000 characters = 1 bite x 2000 characters= 2000 bites
1 bite = 1 x 10^-9 giga bite
------- -----------------------
x bite = 22 giga bite
Cross multiplying
x bite = (22GB) / 1 x 10^-9 GB
x = 2.2 x 10^10 bites
To find how many pages of text the tablet holds we divide the value of 22GB in bites by the number of bites of one page
22GB = 2.2 x 10 ^10 bites
1 page holds 2000 bites
No of pages of text the tablet can hold = (2.2 x 10^10)/2000 = 11000000 pages of text
A 500 page book has 500 x 2000 characters = 1,000,000 characters
1000000 characters = 1000000 bites
The number of 500-page books the tablet can hold =

answer for the B part = 22,000 500-page books
1.5x+5
1.5 is the cost per mile and since x is the variable representing the amount of mile traveled, the 1.5x is the cost per mile. 5 is the fixed cost so it doesn't have a variable attached to it. Hopes this helps. :)
