Answer:
120
Step-by-step explanation:
US stamps = 5/8 × 480
= 300
foreign stamps = 480- 300
= 180
more US stamps than foreign stamps = 300-180
= 120
Answer:
The equation of line is given by

Step-by-step explanation:
We have been given the points (–2, 2) and (0, 5) and we have to find the equation of the line.
Let us first find the slope of the line using the formula

On substituting the values, we get


Now, using the point slope form, the equation of line is given by

Therefore, the equation of line is given by

Answer:
The sum of the arithmetic progression is 2520
Step-by-step explanation:
The sum, Sₙ, of an arithmetic progression, AP, is given as follows;

Where;
n = The nth term of the progression
a = The first term = 100
d = The common difference = -2
Given that the last term = -10, we have;
-10 = 100 + (n - 1) ×(-2)
n = (-10 - 100)/(-2) + 1 = 56
Therefore, the sum of the 56 terms of the arithmetic progression is 
Which gives;

the percent increase in the price of a gallon of milk from 1985 to 2005 is 59%
Define percent increase
Percent increase can be described as the rise in the value of an item, in this case the value is milk.
Write out the parameters
In 1985 the price of a gallon of milk is $2.20
In 2005 the price is $3.50
Formula for percent increase
new price-old price/new price × 100
Calculate the percent increase
new price= $3.50
old price= $2.20
= 3.50-2.20/2.20
= 1.3/2.20
= 0.59 × 100
= 59%
Hence the percent increase from 1985 t0 2005 is 59%

Point slope is in the form y - y1 = m(x - x1)
substitute the values to get
y - 2 = m(x - -8), then simplify
y - 2 = m(x +8)
