If you are going to use mental math, round $0.98 up to $1.
Rounded, the cost of the 30 songs is $30.
However, since you rounded at the beginning, you need to subtract 2 cents for every song you purchased from the total of $30.
Multiply 30 by $0.02 to get $0.60. Subtract $0.60 from $30.
Your answer should be $29.40.
The ratio of the area of the smaller rectangle to the area of the larger rectangle is 1:16
Area of a rectangle
The formula for calculating the area of a rectangle is expressed as:
A = length * width
For the large triangle
Area = 16 * 12
Area of large triangle = 192 square units
For the smaller rectangle
Area = 4 * 3
Area. of small rectangle = 12 square units
Ratio = 12/192 = 1:16
Hence the ratio of the area of the smaller rectangle to the area of the larger rectangle is 1:16

Answer:
Step-by-step explanation:
Thrice the sum of three fifths and two thirds less one half is expressed as 3(3/5 + 2/3)-1/2
Open the parenthesis
3(3/5) + 3(2/3) - 1/2
= 9/5 + 6/3 - 1/2
Find LCM
= 9(6)+10(6)-15/30
= 54+60-15/30
= 54+45/30
= 99/30
= 3 9/30
= 3 3/10
Hence the number id 3 3/10
