mm2

Answers

surface area of a rectangular prism with a base length of 70 mm^2, perimeter of the base is 50 mm. The height of the prism is 9 mm. let a= base length, b = base width, c = height=9. a*b= 70. a+b+9=50, or a+b=41, now bc+ca= c(a+b)=9*41=369 so suface area= 2(ab+bc+ca)= 2(70+369)=878 mm^2

. John Gray bought a basic car for $8,250.00, with options that cost $324.00. There's a 6% sales tax inhis state and a combined $50.00 license and registration fee. What was John's total cost?
A. $9,141.44
B. $14,247.00
C. $9,138.44
D. $10,000.00

Answers

Cost of basic car = $8250
Optional cost = $324
Total cost of basic car and optional items for John= (8250 + 324) dollars
      = 8574 dollars
Then
Percentage of sales tax = 6%
Amount of sales tax = 8574 * (6/100) dollars
   = 514.44 dollars
License and registration fee combined = $50
Then total cost of John in regards to buying the car = 8574 + 514.44 + 50
      = 9138.44 dollars
So option "C" is the correct option in regards to the question given.
