Answer:

Step-by-step explanation:

distance = time * speed

4.9 =  1 second* speed

speed = 4.9/1 = 4.9 cm/sec

time = 15 1/2 = 31/2

distance = 31/2 *  4.9 = 75.95 cm

Answer:

75.95cm

Step-by-step explanation:

<u>4.9 multiplied by 15 will represent the 15</u> <u>seconds</u>

4.9 • 15 = 73.5

<u>4.9 divided by 2 will equal the 1/2 seconds</u>

4.9 ÷ 2 = 2.45

<u>add them all together</u>

73.5 + 2.45 = 75.95 cm

Use the triangle below and the given trigonometric ratio to determine which angle in the triangle below is
4vir4ik [10]
Cosine is the ratio of the adjacent side to the hypotenuse.

In short, we have this equation
cos(angle) = adjacent/hypotenuse

In the case of cos(A) = 18/19.5 we can see that
adjacent = 18
hypotenuse = 19.5

The side of 18 cm is next to angle 2, so the 18 cm side is adjacent to angle 2 (in contrast, the 7.5 cm side is the opposite leg in relation to angle 2)

So that's why the answer is angle 2
In other words, replace the '2' angle marker with 'A' to be able to write cos(A) = 18/19.5

A line is shown in the graph below.
Kay [80]

Answer:

-3/2

Step-by-step explanation:

One can read off the slope of the given line directly from the graph.  As x increases by 3, y increases by 2.  Thus, the slope of the given line is

m = rise / run = 2 / 3

Any line perpendicular to this given line has a slope which is the negative reciprocal of the slope previously found:

                                                      -1              3

Slope of perpendicular line = ------------ = - -----

                                                     2/3             2

This matches the first of the given possible answer choices.

The expression 62.4d-21062.4d−21062, point, 4, d, minus, 210 gives the number of Indian rupees you receive when you exchange \$d
Arisa [49]
<span>601.2 rupees You've been given the equation: r = 62.4d - 210 I will assume that 62.4 is the actual exchange rate and that the 210 is a service fee of some sort for performing the exchange. So with 13 dollars, let's substitute that value into the equation and calculate: r = 62.4d - 210 r = 62.4*13 - 210 r = 811.2 - 210 r = 601.2 So you'll get 601.2 rupees.</span>
