Svetach [21]

Answer:

The best option is to buy Japanese Car.

Step-by-step explanation:

Fuel usage per year is 150000/ 8 = 18750 miles per year

Fuel cost (year 1 -8) = $3.0, $3.06, $3.12, $3.18, $3.25, $3.312, $3.38, $3.5

Japanese Car:

Fuel usage 18750 / 23 = 815 * $3 = $2446  

Fuel charges (year 1 -8) = $2445, $2494, $2623, $2758. $2900, $3050, $3207, $3372

Repair Cost (year 1 - 8) = $700, $721, $742, $764, $787, $811, $835, $860

Insurance cost (Year 1 - 8) = $700, $714, $728, $742, $757, $772, $788, $804

Present value of cost at 5% = 24674.07

Cost of car is $30,000

Total cost = $54674.07

Amercian Car:

Cost $35,000

Fuel usage 18750/20 = 937.5 * $3 per gallon = $2812.5.

Fuel charges (year 1 -8) = $2812, $2913, $2986, $3011. $3098, $3124, $3176, $3208

Repair Cost (year 1 - 8) = $800, $894, $921, $978, $1109, $1176, $1207, $1301

Insurance cost (Year 1 - 8) = $800, $827, $876, $898, $908, $932, $954, $934

Present value of cost at 5% = 25302.18

Cost of car is $35,000

Total cost = $60302.

German Car:

Cost = $45,000

Fuel usage 18750 / 21 = 892 * $3 = $2678  

Fuel charges (year 1 -8) = $2679, $2732, $2786, $2842. $2899, $2987, $3077, $3171

Repair Cost (year 1 - 8) = $1000, $1040, $1081, $1124, $1169, $1216, $1265, $1316

Insurance cost (Year 1 - 8) = $850, $867, $884, $902, $920, $938, $957, $976

Present value of cost at 5% = 27105.73

Cost of car is $45,000

Total cost = $72105.

Mr. Carlevato and Mr. Burrows get into a debate about two different expressions. · Mr. Carlevato says "2(2x + 3) is equal to 4x
ruslelena [56]

Answer:

Yes, the same answer is obtained.

Step-by-step explanation:

According to Mr. Carlevato, 2(2x+3) is equal to 4x+6. However, 2(2x+3) is not equal to 4x+6 according to Mr. Burrows.

Put x=5 in 2(2x+3)

2[2(5)+3]=2(10+3)=2(13)=26

Put x=5 in 4x+6

4x+6=4(5)+6=20+6=26

Therefore,

2(2x+3)=4x+6

Yes, the same answer is obtained.

18 out of the 25 students are going on the field trip. What percent of the students are going on the field trip?
il63 [147K]
Hello.
To find the percentage of how many students went on the field trip, we simply divide 18 by 25. 
18/25 = 0.72

Convert decimal into fraction.
0.72 = 72%

Thus, 18 out of 25 students = 72% of students who are going on the field trip.

You're welcome.

Ooooooooof I need help
snow_lady [41]

Answer:

a) x = -1 and y = -10

Step-by-step explanation:

The first part says find the value of y when the value of x is -3. Then the second part of the question is to find the value of x when the value of y is 2.

so lets solve part a)

y=6x+8\\y=6(-3)+8\\y=-18+8\\y=-10\\\\Now\ when\ y=2\ find\ x\ \\y=6x+8\\2=6x+8\\2-8=6x\\-6=6x\\-6/6=x\\-1=x\\

So answer to part a is x = -1 and y = -10

similarly try the other parts.

Korolek [52]

Answer:

= 868.1ft^3

Step-by-step explanation:

Volume of the square based pyramid = BH/3

B is the base area

H is the height of the pyramid

Base area = Length * Length

Base area = 14.1*14.1

BAse area = 198.81ft^2

Height = 13.1feet

Volume = 198.81*13.1/3

Volume of the pyramid = 868.1ft^3

Hence the volume of a pyramid with the square base is 868.1ft^3
