2 groups if 4 bicyclists or 4 groups of 2 bicyclists. Well it's only 1.75 per truck so since there were 4 trucks 4•1.75=7.00 :)
First of all, look at the figure, The ABC orientation is changed from clockwise to counterclockwise, so an odd number of reflections are involved.
Second, look at the answer choices. Right away, you notice that the last choice (E) involves two reflections. That cannot be the transformation you see. Since that is what the question is asking for, the appropriate choice for the transformation NOT done is ...
... E. reflection across the x-axis followed by a reflection across the y-axis
_____
I have to admit, I went through each of the choices to see if it would work to produce the image you see. All choices except E will do that. All that work turned out to be unnecessary.
<em>Answer:</em>
<em>B</em>
<em>Step-by-step explanation:</em>
<em>If h is hours, then we can substitute 2 into the equation.</em>
<em>K = 30(2) + 40</em>
<em>K = 60 + 40</em>
<em>K = 100</em>
<em>Hope this helps. Have a nice day.</em>
the shortest way is to multiply 12 by 100, then divide that result by 2...
lets test it .... 12×100
= 1200
now 1200 divided by 2 = 600... <u>so answer is 600 </u>
now lets c if its right <u>12 × 50 = 600</u>
∴ this is the easiest solution
Answer:
4 seconds.
Step-by-step explanation:
The function f(x)=-10(x)(x-4) ........ (1), represents the approximate height of a projectile launch on the ground into the air as a function of time in seconds x.
Now, we are asked that for how long from the launch does the projectile stays in the air.
Therefore, we have to solve the equation (1) making f(x) as zero.
Hence, 10x(x - 4) = 0
⇒ x = 0 or x = 4
(As x can not be zero since at x = 0 sec, the projectile was at the ground.}
Hence, x = 4 seconds.
Therefore, the projectile was in the air for 4 seconds. (Answer)
