7 +9.84 + 13.9 = 30.74 gallons of gas in a week
To calculate the sine of an angle, simply divide the length of the opposite side, 479.16, by the length of the hypotenuse, 610. To get the cosine, divide the length of the adjacent side, 377.5, by the length of the hypotenuse, 610.
Answer:n=0.3168
Step-by-step explanation:
Answer:
Step-by-step explanation:
If AB and DE are equidistant from the center, that means that they are the same length. We set the equations equal to one another and solve for x:
3x - 7 = 5(x - 5) and
3x - 7 = 5x - 25 and
18 = 2x so
x = 9. Now we sub that into the expression for AB (or DE since they're the same length):
3(9) - 7 = 20
Both AB and DE measure 20 units.
The value in this case would be going up. Since .75 being multiplied by an increasing number would only increase, the value must be doing the same.
However, if that t were an exponent, the value would be decreasing. The more a number between 0 and 1 is multiplied by itself, the smaller it gets.
