this figure to miles per galllon

Answers

Answer 1

Answer:

Answer:

22.11 miles per gallon

Step-by-step explanation:

1 km = 0.621371 miles

1 litre = 0. 264172 gallon

Given

Mileage of car = 9.4 Milometers per liter of gasoline

Mileage of car = 9.4 Km/ litres

now we will use 0.621371 miles for Km and 0. 264172 gallon for litres

Mileage of car = 9.4 * 0.621371 miles/ 0. 264172 gallon

Mileage of car = 9.4 * 2.3521 miles/ gallon

Mileage of car = 22.11 miles/ gallon

Thus, 9.4 Km/litres is same as 22.11 miles per gallon.

f(n) = 5n - 1, Find f(- 3n).

Answers

Step-by-step explanation:

k(a) = | -2a + 3 | - 1

k(3) = | -2(3) + 3 | - 1 replaced the a with 3

= | -6 + 3 | - 1

= | -3 | - 1

= 3 - 1

= 2

g(x) = 4²ˣ⁻¹ + 7

g(1) = 4²⁽¹⁾⁻¹ + 7 replaced the x with 1

= 4¹ + 7

= 4 + 7

= 11

f(x) = | 8x² - 5x + 3 |

f(-2) = | 8(-2)² - 5(-2) + 3 | replaced the x with -2

= | 8(4) - 10 + 3 |

= | 12 - 10 + 3 |

= | 5 |

= 5

h(x) = -3x + 9

h(-1 + x) = -3(-1 + x) + 9 replaced the x with -1 + x

= 3 - 3x + 9

= 12 - 3x

f(n) = 5n - 1

f(-3n) = 5(-3n) - 1 replaced the n with -3n

= -15n - 1

Step-by-step explanation:

So the part where it says I have won more than 75% of all the games I have played, it is saying he has won more than 75% or 3/4? Which he only won 3/4 not more. 75% is equal to 3/4.
