The subtotal of a dinner bill is dd dollars. There is an 8% dine-in tax, and the customer would like to leave an 18% gratuity based on the subtotal amount. Write an expression that represents the total amount the customer spends on dinner, including the tax and gratuity.

Answers

Answer:

1.26d

Step-by-step explanation:

Given that :

Subtotal = d

Dime - in tax = 8%

Gratuity = 18% of subtotal

Total amount spent on dinner :

Gratuity = 18% of d

Gratuity = 0.18 * d = 0.18d

Dine - in tax : = 8% of dinner bill

Dine - in tax = 0.08d

Total cost of dinner :

Dinner bill + dine - in tax + Gratuity

d + 0.08d + 0.18d

= 1.26d

Total amount spent on dinner = 1.26d

Use the Pythagorean Theorem to find the missing length and then round the result to the nearest tenth a=? b = 5, c = 12 what is A​

Answers

Answer:

Approximately 10.9

Step-by-step explanation:

[tex]a^2+b^2=c^2[/tex]

Plug in b (5) and c (12)

[tex]a^2+5^2=12^2\\a^2+25=144[/tex]

Subtract 25 from both sides

[tex]a^2+25-25=144-25\\a^2=119[/tex]

Take the square root of both sides

[tex]\sqrt{a^2} =\sqrt{119}[/tex]

a = approximately 10.9

280/3 = 93.333333

Answer:

Since there are 60 minutes in an hour and 20/60 = 1/3, you can divide 280 by 3 to get the amount of miles travelled in 20 minutes.

Given the definitions of f(c) and g(x) below, find the value of g(f(5)).
f(x) = 2x – 10
g(x) = x2 + 6x – 8

Answers

Answer:

gf(5) = -8

Step-by-step explanation:

gf(x) = g(x^-1) = x^2 + 6x - 8

f(x) = 2x - 10

gf(x) = 6(2x - 10) - 8

gf(x) = 12x - 60 - 8

gf(x) = 12x - 68

gf(5) = gf(x) = 12x - 68

gf(5) = 12(5) - 68

gf(5) = 60 - 68

gf(5) = -8
