<span>Total pocket money: N600
Spent as follows:
Books N50
Pen N80
Maths set N270
Bag N150
Food N50
To find: Angles that pen and food represent on pie chart.
Solution: Pie is made on circle, and sum of angles of a circle is 360°.
Angle that pen represent = (80/600)*360° = 48°
Angle that food represent = (50/600)*360° = 30°</span>

Where is the answer choice????
Answer:
B. 3×10^13
Step-by-step explanation:
The first two digits are fixed at one of three pairs of values; the last digit is "fixed" as the check digit, leaving 16 - 3 = 13 free digits. These can take on any of 10^13 values.
The total number of possible card numbers is 3×10^13.
Simply distribute, multiplying the coefficients and adding exponents when necessary...
<span>-5p^3 (4p^2 + 3p - 1)
The first term I'll explain then just do the rest
-20p^5
because -5*4 = -20 and p^3 * p^2 = p^5. Since we are multiplying bases with exponents, we keep the bases and add the exponents, now for the rest of the expression
