A van travels at a constant speed of 15m/s for 60 seconds. for 30 seconds. a. show this on a graph. Put time on the horizontal axis and speed on the vertical axis.
b. The speed of a car increases steadily from 0 m/s to 30 m/s over 20 seconds. It travels at 30m/s for 30 seconds. Then the speed steadily decreases from 30 m/s to 0 m/s in 10 seconds. show the speed of the car on the same graph.
c. For how many seconds is the car travelling faster than the van

step-by-step explanation:

*calories burned = (weight)(calorie factor)*

calories burned = 180 (0.65)

calories burned = 117

the calories he used up is 117, which is 65% of his weight.  

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.

step-by-step explanation:

at each of the parallel lines adjacent angles are supplementary. the angles have special names identifying their positions with respect to the parallel lines and transversal. they are corresponding angles, alternate interior angles, or alternate exterior angles. an angles is congruent to its matched angle.
