The system of equations are y = 35 - 2.2x and y = 1.7x
<em><u>Solution:</u></em>
Given that, office building has two elevators.
<em><u>One elevator starts out on the 4th floor, 35 feet above the ground, as it’s descending at a rate of 2.2 feet per second</u></em>
Let "x" be the number of seconds for which the elevator is descending
Therefore, for "x" seconds the descended feet is 2.2x feet
The elevator is at 4 th floor, 35 feet above ground
Therefore, from 35 feet, the elevator has descended 2.2x feet for "x" seconds
Let "y" be the final position of elevator after "x" seconds
Therefore,
y = 35 - 2.2x
<em><u>The other elevator starts out at ground level and is rising at a rate of 1.7 feet per second</u></em>
Here, the elevator is rising at a rate of 1.7 feet per second
Therefore, for "x" seconds, the elevator has raised 1.7x feet
Here the elevator is at ground level, therefore
y = 1.7x
Thus the system of equations are y = 35 - 2.2x and y = 1.7x
I think the answer is 9.3, but I’m not sure
209 action figures on his wall
380/100 = 3.8
so there would be 3.8 action figures per 1%
then 3.8*55 =209

Please, please give brainliest, it would be greatly appreciated, I only a few more before I advance, thanks!
There are 8 possible outcomes for a marble being drawn and numbered.
{1,2,3,4,5,6,7,8}
There are 4 possible outcomes for a card being selected from a standard deck.
{ <span>hearts, diamonds, clubs, spades}
So the number of outcomes in the sample space would be 8 x 4 = 32.
In the event "an even number is drawn", there are only 4 possible outcomes for a marble being drawn, {2,4,6,8}, whereas there are still 4 possible outcomes for a suit. So the number of outcomes in the event is 4 x 4 = 16.
</span><span>In the event "a number more than 2 is drawn and a red card is drawn", there are 6 possible outcomes for the marble being drawn, {3,4,5,6,7,8}, whereas there are only two possible suits for a card being selected as red, {heart, diamond}. So the number of outcomes in this event is 6 x 2 = 12.
In the event </span><span>"a number less than 3 is drawn or a club is not drawn", the number drawn could be 1 or 2 whereas a spade/heart/diamond could be selected. So the number of outcomes is 2 x 3 = 6.</span><span>
