The sticker price is $40,000

The option price is $6000

Destination fees are $800

The base sticker price is 90% of the price i.e.

[tex]\Rightarrow 90\%\times 40,000\\\Rightarrow 0.9\times 40,000\\\Rightarrow \$36,000[/tex]

The option price is 80% of included options i.e.

pedro's car averaged 957 miles on its 29-gallon tank of gas. If pedro runs out of gas and a mechanical comes to his rescue with 2 3/4 gallons of gas, determine how far his car can go. Round to the nearest​

Answers

Answer:

His car can go 90.75 miles.

Step-by-step explanation:

We solve this question using proportions.

Pedro's car averaged 957 miles on its 29-gallon tank of gas.

This means that per gallon, his car can go:

957/29 = 33 miles.

2 3/4 gallons of gas

[tex]2 + \frac{3}{4} = 2 + 0.75 = 2.75[/tex] gallons.

Determine how far his car can go.

For each gallon, the car goes 33 miles. He has 2.75 gallons, so his car can go 33*2.75 = 90.75.

His car can go 90.75 miles.

A rectangular prism has a surface area of 8 square feet. A similar rectangular prism has a surface area of 200 square feet. How many times larger are the dimensions of the larger prism?

5
10
25
625

Answers

The number of times larger the dimensions of the larger prism with surface area of 200 ft² to the smaller prism of 8 ft² is 25 times.

Surface area of a rectangular prism

The surface area of a rectangular prism is as follows;

surface area = lwh

where

l = lengthw = widthh = height

Therefore,

surface area of the first prism = 8 ft²

surface area of the second prism = 200 ft²

Therefore, the number of times larger the dimensions of the larger prism with surface area of 200 ft² to the smaller prism of 8 ft² is as follows;

200 / 8 = 25

Convert 49° Celsius to degrees Fahrenheit using the following formula: F = {C+32 O A. 506.5°F OB. 196.2°F C. 94.6°F OD. 2237°F O E. 120.2°F​

Answers

Answer:

Step-by-step explanation:

F = 9/5C + 32

Putting value

9/5(49) + 32

88.2 + 32

= 120.2°F

Option E is the correct answer

The Celsius temperature 49 in Fahrenheit is 120 F.

To convert Celsius to Fahrenheit, you can use the formula:

F = (C × 9/5) + 32

Let's calculate the conversion using the given Celsius value:

C = Celsius temperature

F = (C × 9/5) + 32

F= (49 x 9/5)+ 32

F= 88.2 + 32

F = 120.2 F

Thus, Celsius temperature 49 in Fahrenheit is 120 F.

Find the number of distinct arrangements of the 9 letters in SEVENTEEN. Two of the same letter are considered identical (not distinct).

Answers

The number of distinct arrangements of the 9 letters in SEVENTEEN is 7560

The number (n) of letters in SEVENTEEN is given as:

[tex]n = 9[/tex]

The repeated letters are E and N, and their frequencies are:

[tex]E=4[/tex]

[tex]N = 2[/tex]

So, the number of distinct arrangements is calculated as:

[tex]Arrangements = \frac{n!}{E!N!}[/tex]

Substitute values for n, E and N

[tex]Arrangements = \frac{9!}{4! \times 2!}[/tex]

Expand the factorials

[tex]Arrangements = \frac{362880}{24 \times 2}[/tex]

[tex]Arrangements = \frac{362880}{48}[/tex]

Evaluate the quotient

[tex]Arrangements = 7560[/tex]

Hence, the number of distinct arrangements is 7560
