Answer:
1 pound for $3.75
if you divide $15.63 by 4, you would get 3.9075, which is more than $3.75
Step-by-step explanation:
Answer:
Given formula is :
S = 
We have p = 8500
r = 12.7% or 0.127
(a) when t = 18 months or 
years
S = 
=
=
= 1.20985
S = $10283.73
(b) Investment doubles means S = 
=> 
Taking log on both sides
We get t = 5.45 years
(2x^4 + 3x^2)(x^2-1)
you multiply and you'll get:
2x^8-2x^4+3x^4-3x^2
then add the coefficients with x^4
= 2x^8+1x^4-3x^2
the coefficient for x^4 is 1, so the answer is B
The difference between the perimeters of the two rectangles will be 4x + 3
The formula for the perimeter of rectangle is given as :
P = 2(L + B)
Where P = perimeter of the rectangle
L = length of the rectangle
B = breadth of the rectangle
Now we have given two rectangle on is smaller than the other.
To find the difference between the perimeter of the two rectangles. We will first calculate the perimeter of both the rectangle.
Perimeter of the bigger rectangle = 2( 5x + 3 + 2x)
= 2(7x + 3)
= 14x + 3
Perimeter of the smaller rectangle = 2(2x + 3x)
= 2*5x
=10x
Difference between the two perimeters = (Perimeter of the bigger rectangle) – (Perimeter of the smaller rectangle)
= (14x + 3) – 10x
= 4x + 3
Thus the difference between the perimeters of the two rectangle will be 4x + 3

Answer:
If it is a simple average, the average is 2.8 points.
If it is a weigthed-by-credits average, the average is 2.86 points.
Step-by-step explanation:
To calculate the simple average of this 5 grades, we sum all the points and divide it by 5:
In Algebra: A = 4 points
In History: B = 3 points
In Sociology: A = 4 points
In English: D = 1 point
In Seminar: C = 2 points
Average = (4+3+4+1+2)/5 = 2.8 points
If the average is weighted by the credits, we must add each score multiplied by the credits and, in total, divide it by the total amount of credits.
