IgorC [24]

The coordinates of point B' are (-3, 6).

<h2>Given that</h2>

Triangle ABC has vertices A(4, 5), B(0, 5), and C(3, –1).

The triangle is translated as 3 units to the left and 1 unit up.

<h3>We have to determine</h3>

What are the coordinates of B' after the translation?

<h3>According to the question</h3>

Triangle ABC has vertices A(4, 5), B(0, 5), and C(3, –1).

The triangle is translated as 3 units to the left and 1 unit up.

To find the coordinates of B', we will shift the x-coordinate of point B to left by 3 units and the y-coordinate of point B to 1 unit up.

After the given transformation the coordinates of point B' would be:

\rm B(0, \ 5) = B (0-3, \ 5+1) = B(-3, \ 6)

Therefore, the coordinates of point B' are (-3, 6).

A moving walkway at the airport moves at a pace of 1.8 feet per second. If you stand on the walkway as it moves, how long will i
miv72 [106K]

Answer:

150 seconds

Step-by-step explanation:

use the velocity equation of

V=\frac{delta(D)}{Delta(T)\\}

Where V is in feet per second, Delta D represents the change in displacement and delta t represents the change in time

all you need to do is rearrange the equation to find Delta(T)

as such...

Delta(t)*V=Delta(D)\\Delta (t)=\frac{Delta(D)}{V}\\Then\ insert\ your\ corresponding\ values\\\Delta(t)=\frac{270 ft}{1.8 feet/sec}  \\Delta (t)= 150sec

The drama club sold 415 Manatee tickets to the school's play for $7.95 each 18 of the tickets were refunded estimate the tickets
nevsk [136]
Since you always round up when you estimate in the middle lets say theres 420 tickets. Each is 7.95, but we'll round it to 8.00. 420x8.=3,360. After that part we need to find about how much tickets were refunded. So we round 18 to 20 and each ticket is still 8$. 20x8=160. Finally in all, we do 3,360-160=3200. Its an overestimate because we rounded up. Im not sure what else youre asking but thats the basic answer.

For a certain experiment, if we expect to get a red marble twelve times in 60 trials, what is the theoretical probability of get
MrRa [10]

Answer:

1/5

Step-by-step explanation:

You expect to get 12 red marbles out of 60 trials.

So, you expect to get a red marbles 12/60 of the times.

We can simplify that 12/60 to 1/5, which is a choice of answers. :-)

We assume here you correctly assume your probability level when you did your forecast of 12/60.  And either you're picking from a small pool and re-insert the marble, or you have a very large amount of marbles (at least 60).
