Based on the right angle triangle and the given parameters, cos K = 5/13

<h3>Trigonometric ratios</h3>

sin = opposite / hypotenuse

cos = adjacent / hypotenuse

Tan = opposite / adjacent

Given parameters:

Hypotenuse = 13
Adjacent = 5
Opposite = 12

Therefore,

cos K = adjacent / hypotenuse

cos K = 5/13

The gas tank in the car holds 20 gallons of gasoline. You used up 4 gallons and 1 quart on your trip. How much gasoline is left

erma4kov [3.2K]

There are 4 quarts in a gallon so the amount used can be shown as 4 1/4, or 4.25 so to find out how much gas is left in the tank you simply subtract 4.25 from 20.

20-4.25

=15.75

There is 15.75, or 15 3/4, gallons of gasoline left in the tank.

Cabs charge $3.60 Flag Fall plus $2.19 per km. (a) Write down an equation to calculate the cost, C, of cab fare for a distance d

Softa [21]

(a) C = 3.60+2.19d

(b) The cab fare will be $36.45 for a distance of d kilometers.

Step-by-step explanation:

Given,

Charges of Flag Fall = $3.60

Per kilometer charges = $2.19

Let,

d be the total distance.

C be the total cost for d kilometers.

(a) Write down an equation to calculate the cost, C, of cab fare for a distance d kilometres.

Total cost = Charges of flag fall + Per kilometer charges * distance

C = 3.60+2.19d

(b) Use your equation to calculate the cost of cab fare for a distance of 15 km.

Here,

d=15

Putting in Equation

$C=3.60+2.19*15\\C=3.60+32.85\\C=36.45$

The cab fare will be $36.45 for a distance of d kilometers.

3W - 8 + 3W = -4 + 5W - 5<br> can someone do it and show the work / how you did it

andrew11 [14]

Answer:

W = -1

Step-by-step explanation:

3W - 8 + 3W = -4 + 5W - 5

combine like terms

6W - 8 = -9 + 5W

subtract 5w on both sides

W - 8 = -9

add 8 on both sides

W = -1
