D would be the most reasonable because the whole set up adds up to 10 and you only have a chance of drawing all of the colors in a row
Answer:
After 10 years the cost will be $ 97.52.
Step-by-step explanation:
This problem requires us to calculate the cost of graphing after 10 years if inflation rate is two percent. This can easily be calculated by compounding present value of current cost at the rate of 2%. Detail calculation is given below.
FV= 80 (1+2%)^10
FV = $ 97.52
Answer:
the daily fee =33 dollars
and the mileage charge.=0.35
Step-by-step explanation:
let d: be daily fee and m for mileage
cost of rental =(d*number of days)+ (m*number of mileage)
her first trip: 4d+440m=286
her second trip: 3d+190m=165.5
solve by addition and elimination
4d+440m=286 ⇒ multiply by 3 ⇒12d +1320m=(3)286
3d+190m=165.5⇒ multiply by 4⇒12d+190(4)m=4(165.5)
12d+1320m=858
12d+760m=662
subtract two equation to eliminate d
12d+1320m-12d-760m=858-662
560m=196
m=7/20=0.35 for on mileage
d: 4d+440m=286
4d=286-440(0.35)
d=(286-154)/4 33 dollars

Step-by-step explanation:
In this problem I'm assuming the office is rectangular.
so
The area of rectangle is equal to
where
L is the length of the rectangle
W is the width of the rectangle
In this problem we have
so
------> equation A
Find two possible dimensions of the office
case A) Assume a length side L and find the value of W in the equation A
so
For 
substitute in the equation and solve for W
The dimensions are by
case B) Assume a length side L and find the value of W in the equation A
so
For 
substitute in the equation and solve for W
The dimensions are by
