The figure shows a trapezium PQRS where RS = 17m and PS = 15m. If PT = 14m, and the area of trapezium is 196m2, Find the length PQ.
Answers
Answer:
PQ = 11 m
Step-by-step explanation:
In trapezium PQRS,
PQ and RS are parallel lines and PT is the perpendicular distance between the parallel lines
a = PQ
b =RS = 17 m
d = PT = 14 m
[tex]\frac{(a+b)*d}{2}= 196\\\\\frac{(PQ + 17)*14}{2}=196\\\\(PQ + 17) * 7 = 196\\\\PQ + 17 = \frac{196}{7}\\\\PQ + 17 = 28\\\\PQ = 28 - 17\\\\PQ = 11[/tex]
What is the value of x?
Answers
Answer:
28!
Step-by-step explanation:
soooooo its a 90 degree angle
2x+1+33=90
2x+34=90
-34
2x=56
x=28
Answer:
x = 28°
Step-by-step explanation:
As you see that the angle is an right angle where right angles = 90°
So,
(2x + 1) + 33 = 90°
Subtract 33 on both sides:
2x + 1 = 57
Subtract 1 on both sides:
2x = 56
Divide 2 on both sides:
x = 28°

Rebecca is playing a video game that involves planting and cutting down trees. She moves up an energy level for each tree she plants, and she moves down a level for each tree she cuts. If Rebecca reaches energy level 10, she will earn bonus points.
Rebecca is currently at energy level 4. The results of her next 3 turns are:
Turn 1: 6 trees cut
Turn 2: 8 trees planted
Turn 3: 1 tree cut
3. What is Rebecca's energy level after Turn 2?
4. What is Rebecca's energy level after Turn 3? Will she earn bonus points after Turn 3? Explain why or why not.
Answers
Answer:
3. 6 energy points after turn 2
4. 5 energy points after turn 4
no bonus points cause she never reached 10 points
4. Rebecca’s energy level after turn 3 would be 5. Rebecca’s not going to earn any additional points due to her not being the required energy level.

Step-by-step explanation:
Answer:
x = -4
Step-by-step explanation:
-9 (1/2x - 3) = 45
Divide both sides by -9
1/2x - 3 = -5
Add 3 to both sides
1/2x = -2
multiply both sides by 2
x = -4
Carla and four of her friends went to the movie theater and found that there were only five seats left in the theater. How many different ways can Carla and her friends sit in these five seats?
A. 24
B. 120
C. 256
D. 396
Answers
Answer:
24
Step-by-step explanation:
Answer:B
Step-by-step explanation:
The number of different ways Carla and her friends can sit in the five seats can be calculated using the concept of permutations. Since there are 5 seats available and 5 people, each person can occupy one seat.
The number of ways to arrange the 5 people in the 5 seats can be calculated as 5 factorial (5!). The factorial of a number is the product of all positive integers less than or equal to that number.
5! = 5 * 4 * 3 * 2 * 1 = 120
Therefore, the correct answer is B. 120.

What is the median of these numbers :
90, 95, 92, 93, 91, 97
Answers
Answer:92.5
Step-by-step explanation:
The middle numbers are 92 and 93 and then you add 92+93=185 and 185/2=92.5
Work :
1) Place the numbers in order
90, 91, 92, 93, 95, 97
2) There are two medians (92 & 93)
3) Add both numbers then divide by 2, because it’s two numbers and you need 1 median
92+93 = 185/2 = 92.5

What is the scale factor of the dilation?
Is the dilation an enlargement or a reduction?
Answers
Answers:
Scale Factor = 3/4
This is a reduction
======================================================
Explanation:
Let's focus on the point R(4,4). That's the preimage point for the image of R ' (3,3).
Let k be the scale factor. We multiply this value of k by the x,y coordinates of point R to jump to R '
we have x = 4 jump to 4k which is the x coordinate of point R'
So we set 4k equal to 3 and solve for k to get k = 3/4. The scale factor is 3/4 or 0.75
We have a reduction since the image triangle T'R'S' is smaller compared to the preimage triangle TRS. We can see that we have a reduction by looking at the scale factor. If 0 < k < 1, then we have a reduction. If k > 1, then we have an enlargement instead. So we go with the first option since 0 < 3/4 < 1 or you could say 0 < 0.75 < 1.
Answer:
A reduction (think shrinking) is a dilation that creates a smaller image, and an enlargement is a dilation that creates a larger image
