# Jerome got in the elevator on the first floor of his office building. He went up 18 floors to his office. Then, Jerome took the stairwell down 3 floors for a morning meeting. After the morning meeting, he took the elevator down 8 floors for lunch in the cafeteria. Then, Jerome took the stairwell up 5 floors for an afternoon meeting. On which floor was his afternoon meeting? A. thirty-fifth B. nineteenth C. thirteenth D. third

He starts on the 1st floor. He then goes up 18 floors:

1 + 18 = 19

He took the stairwell down 3 floors

19 - 3 = 16

He then takes the elevator down 8 floors

16 - 8 = 8

He then takes the stairwell up 5 floors for his afternoon meeting

8 + 5 = 13

hope this helps

So he started on the 1st floor then went up 18 floors which would leave him on the 19th floor. Then he went down 3 floors which would leave him on the 16th floor. Then he went down 8 more floors, leaving him on the 8th floor. Finally, he went up 5 floors which would leave him on the 13th floor.

Therefore, the correct answer is C. Thirteenth

Hope this helps

## Related Questions

there were 180 people at a civic club fundraiser. members paid 4.50 per ticket, no members paid 8.25 per ticket. if the total receipts amounted to 1222.50 how many members and how many nonmembers attended the fundraiser

X= # of members
y= # of nonmembers

QUANTITY EQUATION
x + y= 180

COST EQUATION
\$4.50x + \$8.25y= \$1222.50

STEP 1:
Use substitution or elimination to solve. I'm using elimination. Multiply quantity equation by -4.50 to eliminate the x term and solve for y.

-4.50(x + y)= -4.50(180)
-4.50x - 4.50y= -810

STEP 2:
Add the cost equation and the step 1 equation together. The x term is cancelled and we solve for y.

\$4.50x + \$8.25y= \$1222.50
-4.50x - 4.50y= -810

3.75y= 412.50
divide both sides by 3.75

y= 110 nonmembers

STEP 3:
Substitute the y value into either original equation to solve for x.

x + y= 180

x + 110= 80
subtract both sides by 110

x= 70 members

CHECK:
use the opposite equation as chosen for step 3.

\$4.50x + \$8.25y= \$1222.50
4.50(70) + 8.25(110)= 1222.50
315.00 + 907.50= 1222.50
1222.50= 1222.50 √

ANSWER: There were 70 members and 110 nonmembers attending.

Think of the letter X as four-vectors starting from the center and pointing outward. Label the four vectors starting from the top left and proceeding clockwise as U, V, W, Z a) point in or out of the page? (in/out)
b)Does point in or out of the page? (in/out)
c)Compute U X V = ?

The letter X as 4 vectors

The letters such as U, V, W, and Z are given starting from the center in pointing outwards with labels of the above four vectors starting in the top left and moving in a clockwise direction.

The answer is in inwards and outwards.

• As per the vectors point out if the page the first answer is a cross product of U multiplied by V points inwards to the page.
• The second answer is the cross product of the U is multiplied by Z thus pointing outwards of the page.
• The last answer is U x W = < 0, 0, 0 >.

The Question is incomplete, here is the complete Question:

Think of the letter X as four vectors starting from the center

and pointing outward. Label the four vectors starting from the

top left and proceeding clockwise as U, V, W, Z.

1. Does U x V point in or out of the page? (in/out)____
2. Does U x Z point in or out of the page? (in/out)____
3. Compute U x W=

1. The Cross Product of U x V points inwards the page.
2. The Cross Product of U x Z points outwards the page.
3. U x W = < 0, 0, 0 >

Step-by-step explanation:

CROSS PRODUCT:

When we talk about vectors then we have the cross product of two vectors which is defined as the product of the magnitude of the two vectors and the sine of angle between them.

Mathematically,

|a|.|b|. sin∅

Thus when a and b are two non-zero vectors, then a x b = 0, if and only if a and b are parallel to each other. In order to find the direction of any two vectors we use the right hand rule and according to that we can predict the direction of the cross product of the two vectors whether they are inwards or outwards.

In this case for part (1) both the vectors are acting inwards as they are in same direction, in part (2) they are opposite in direction so it is acting outwards and in part(3) the cross product will be 0 for all the three planes as they both are parallel to each other.

The Houston rockets scored 66 points in the second half. There are 24 minutes in a half. What was the average number of points per minute?

The answer is 2.75, I believe.

Anna can type 123 in 3 minutes ,caroline can type220 words in 5 minutes who can type faster

Caroline.
If you divide 123 by 3 to see how many words Anna types per minute, its comes to 41 words/minute. Dividing 220 by 5 to find the words/minute Caroline types would result in 44 WPM.
Hello! To solve this problem, we'll need to find a common denominator and set each ratio accordingly.

Anna- 123 in 3 minutes
123:3

Caroline- 220 in 5 minutes
220:5

Both 3 and 5 can go into 15.

Anna can type faster than Caroline. Hope this helps! :)
