How many times would you predict to roll a sum of 12 out of 180 rolls? Show your work.
Answers
Answer:
5.
Step-by-step explanation:
On 1 roll of 2 dices probabilty of 12 = 1/6 * 1/6 = 1/36
So the prediction ffor 180 rolls
= 1/36 * 180
= 5

Triangle PQR is transformed to triangle P′Q′R′. Triangle PQR has vertices P(8, 0), Q(6, 2), and R(−2, −4). Triangle P′Q′R′ has vertices P′(4, 0), Q′(3, 1), and R′(−1, −2).
Plot triangles PQR and P′Q′R′ on your own coordinate grid.
Part A: What is the scale factor of the dilation that transforms triangle PQR to triangle P′Q′R′? Explain your answer. (4 points)
Part B: Write the coordinates of triangle P′′Q′′R′′ obtained after P′Q′R′ is reflected about the y-axis. (4 points)
Part C: Are the two triangles PQR and P′'Q′'R′' congruent? Explain your answer. (2 points)
Answers
Answer:
The scale factor from triangle PQR to P'Q'R' is 1/4.
The length of each side of the triangle is divided by 4, in other words it is multiplied by the scale factor of 4.
If P'Q'R" is reflected over the y-axis the new points would be: (1, 0) (0, 1) and (-2, 1).
No, the triangles are not congruent. There was a dilation of 1/4 in the triangles.

Task:
Engineers are digging a 3200-foot-long tunnel at a constant rate. After 5 months, the engineers still need to dig 1700 feet to finish the project. How much time does it take to complete the tunnel from start to finish?
Will the engineers have enough time if the project was started in December 2020 and the deadline to finish the project was in August 2021? Please explain your answer for yes or no.
Hint:
y=mx+b (slope-intercept form)
x=time
y=distance
b=3200
Start & Finish: ??
Total length=3200ft
Answers
Answer:
318 days or 10.6 months,
No, because the time between august and december is 8 months and it would take 10 to complete the tunnel
Step-by-step explanation:
start by determining the slope:
subtract the remaining distance from the total distance to determine distance so far, then divide by time.
m = (3200 - 1700)/5
m = 1500/5
m = 300
y = mx + b
Plug in to solve for x.
3200 = 300x + 0
3200 = 300x
divide y by m. This is x. (this is known as inverse operation if you didnt know already.)
3200 = 300(10.6_)

Answers
Answer:
23.75
Step-by-step explanation:
Answer:
23.75
Step-by-step explanation:
1. 23.8 - 23.7 = 0.1
2. 0.1 ÷ 2 = 0.05
3. 0.05 + 23.7 = 23.75
this works because to find the middle of two numbers (in this explanation 10 and 20), you have to subtract the larger one from the smaller one (20 - 10 = 10) and take your sum and divide it by two (10 ÷ 2 = 5) and then add it back to the smaller number (5 + 10 = 15 = 1/2 the midpoint of 10 and 20)
Find the correct plugged in formula for each figure.

1)What if you have two equations equal to y? How do you solve for x?
2)If you need to solve for a variable to substitute, what is your first step?
3)What does it mean to substitute for a value?
Answers
Answer:
Step-by-step explanation:
If you have two equations for y, eliminate y by setting these two equations equal to one another. Solve the resulting equation for x. Then substitute your x value into one of the equations for y. Write your solution as (x, y).
2) If you need to solve for a variable to substitute, what is your first step? Example: If you have two equations for y, eliminate y by setting the two equations equal to each other. This decides for you that you must solve for x.
3) What does it mean to substitute for a value? Example: If you have y = 3x and 2x + y = 17, replace y in the second equation with 3x. This eliminates y and allows you to solve for x.

2. 200.52 4. 212.67 5. 148.48
Step-by-step explanation:
for (2) you find the area of each shape first the square
12*12=144
then you find the area of the semicircle
the formula is A= (3.14)r^2/2
the (r) is 6 because that is half of the whole side of the semicircle
so... (3.14) 6^2/2
6*6= 36
(3.14)36/2
113.04/2
56.52
then add the 144 from the square to it
56.52+144
200.52

-85.5 (area of the triangle)
-127.17 (area of the semicircle)
