Consider these four line graphs representing speed in meters/second, where each x-axis is labelled in seconds and each y-axis is labelled in meters. what do the four graphs have in common? a) they all indicate a constant speed. b) they all indicate an increase in speed. c) all four graphs have nothing in common. d) they all represent the same speed in m/s

Answer : (A) They all indicate a constant speed.  

Explanation :

In this case, four line graphs represent speed in m/s. The x-axis is labeled in seconds (time) and the y-axis is labeled in meters (distance).

The slope of the distance-time graph gives the slope. It can be seen from the attached figure that, in each case, the speed is constant everywhere.  

Hence, the correct option is (A) " They all indicate a constant speed ".

6 meters

step-by-step explanation:

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
