How many times would you predict to roll a sum of 12 out of 180 rolls? Show your work.
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

Answer:
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
question (4)
-85.5 (area of the triangle)
-127.17 (area of the semicircle)
212.67
question (5)
-48( area of triangle)
-100.48 (area of semicircle)

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
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_)

= 2(13 x (6 ÷ 2))
= 2(13 x 3)
= 2 x 39
= [tex]78in.^{2}[/tex]

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?
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.

Expand the expression 3(5p+1) using the distribution property
PLEASE HELP
Answer:
15p + 3
Step-by-step explanation:
Multiply 3 by each number in the parentheses and keep the variable
Using the distribution property 3(5p + 1) is 15p + 3.
What are the basic properties of arithmetic laws of operations?There are three types of basic arithmetic laws of operation.
Commutative law for addition and multiplication states,
a + b = b + a.
a×b = b×a.
Distributive law states,
a(b ± c) = ab ± ac.
Associative law states,
a + (b + c) = (a + b) + c.
Given, An expression 3(5p + 1).
= 3×5p + 3×1.
= 15p + 3.
