Each single digit gets its own box.
=======================================
Explanation:
Each row of three values must multiply to 12. We see that happening with the first two cuboids.
Cuboid A: 1*1*12 = 12
Cuboid B: 1*2*6 = 12
-------------
For cuboid C, we have two blank spaces multiplied with 4. Let's call these blank spaces x and y. We want to solve the equation x*y*4 = 12.
Divide both sides by 4 and you'll get x*y = 3
Since x and y are positive integers, this must mean either
x = 1 and y = 3
or
x = 3 and y = 1
Those are the only ways to multiply to 3 with two integers. But we can rule out the second case because the instructions say "Put the answers in order of size from left to right". Basically your teacher wants them sorted from smallest to largest. Refer to cuboid B for an example of what I mean.
So this means we have the values: 1, 3, 4 for cuboid C
---------------
Cuboid D is a similar story
Let x and y be the blank spaces. We can see that x*y*3 = 12 which becomes x*y = 4 after dividing both sides by 3.
This time we have three ways to do this and they are
x = 1 and y = 4x = 2 and y = 2x = 4 and y = 1We can immediately rule out x = 4 and y = 1 because we need the answers sorted from smallest to largest.
We can also rule out x = 1 and y = 4 because the sequence 1,4,3 is not fully sorted from smallest to largest. Note how this is effectively a repeat of cuboid C (just in a different order).
The only thing left is x = 2 and y = 2
For cuboid D we have these dimensions: 2, 2, 3

what will be the additive is 4
Answer:
The two addends in an addition equation are interchangeable, which means that the answer to "What is the additive inverse of -4?" or "What is the additive inverse of negative 4?" is 4. Since the additive inverse of 4 is -4, additive inverse is also known as the opposite number.

The pressure, P (in lbs/ft2 ), in a pipe varies over time. Five times an hour, the pressure oscillates from a low of 90 to a high of 230 and then back to a low 90. The pressure at t = 0 is 90.
Question: Find a possible formula for P=f(t)
P=160-70*cos(2π*(1/12)*t)
• Pressure in mathematics or physics is defined as force per unit area. The pressure exerted by a solid object which is resting on top of a solid surface is the weight divided by the area of the object . SI unit of force is Newton (N).
First, we find the amplitude by taking the difference between the peak values and dividing by two:
Amplitude=(230+90)/2=70
We can find the center value by either adding 70 to the minimum or subtracting 70 from the maximum:
90+70=160
230-70=160
This tells us that the Center Value=160
The frequency that we are operating at is given as:
f = 5/hour
so in minutes
f=5*(1/60)/minute=5/60=1/12 per minute
So, combining everything we get
P=160-70*cos(2π*(1/12)*t)

The pH measurements of water specimens from various locations along a given river basin are Normally distributed with mean 8 and standard deviation 0.3. What is, approximately, the probability that the pH measurement of a randomly selected water specimen is a value between 7.5 and 8.2?
A. 0.3003
B. 0.6997
C. 0.9522
D. 0.9902
Answer:
0.699733
Step-by-step explanation:
Given that :
Mean (m) = 8
Standard deviation (s) = 0.3
Probability that pH is between 7. 5 and 8.2
Probability of pH < 7.5
P(x < 7.5)
The standardized score (Z) :
Z = (x - m) / s
Z = (7.5 - 8) / 0.3 = - 1.6667
p(Z < - 1.6667) = 0.047787 ( Z probability calculator)
Probability of pH < 8.2
P(x < 8.2)
The standardized score (Z) :
Z = (x - m) / s
Z = (8.2 - 8) / 0.3 = 0.6667
p(Z < 0.6667) = 0.74752 ( Z probability calculator)
Hence,
p(Z < 0.6667) - p(Z < - 1.6667)
0.74752 - 0.047787 = 0.699733

A project consists of three tasks: A, B, and C. Task A is known to take five days for sure. Tasks B and C are each dependent on A. B takes five days. C takes seven days with a probability of 0.5 and three days with a probability of 0.5. What is the expected completion time of the project
Answer:
The expected completion time of the project is:
10 days.
Step-by-step explanation:
Duration of Task A = 5 days
Task B and C depend on Task A
This implies that Task A must be completed before Task B and C can be started.
To complete Task B will take 5 days
To complete Task C will take 5 days (7 * 0.5) + (3 * 0.5)
Since Task A takes 5 days and Tasks B and C depend on Task A and Task B takes 5 days and Task C takes expected time of 5 days, it means that the project can be completed in 10 days (5 + 5) if tasks B and C are simultaneously carried out.
The expected completion time of the project is
(i)10 days if B&C are mutually independent
(ii)15 days if B &C are mutually dependent
What is the expected completion time of a task?Expected completion time of a task= p1x1 + p2x2
Where
p1 & p2 are probabilities.
x1 and x2 are samples.
p1=p2=0.5
x1=7
x2=3
Expected completion time of task C= 0.5*7+0.5*3 = 5 days
Task B and C will be due till task A is not accomplished.
Total time to accomplish task A = 5 days
Total time to accomplish task B= 5 days
Expected time to accomplish task C = 5 days
If tasks B and C are mutually independent
expected time to complete the project = 5+5=10days
If task C depends on task B
Expected time to complete the project = 5+5+5 = 15 days.
Therefore
The expected completion time of the project is
(i)10 days if B&C are mutually independent
(ii)15 days if B and C are mutually dependent

Sean bought 3/7 of a pound of cherries and then he ate 1/4 of a pound of them. When he got home, he saw that he still had 2/3 of a pound of cherries in his cupboard. How many total pounds of cherries does he have? Give your answer as an exact simplified improper fraction, not as a mixed number. Do not include units.
Answer:
71 /84
answer is not in imporper fraction.
Step-by-step explanation:
fractions need to be changed or converted to equivalent fractions inorder to solve them.
1.Total amount of cherries he bought and he already had in cupboard= 3/7 + 2/3
convert them to equivalent fractions inorder to add them by using LCM of the denominators.Which in this case is 21 (LCM of 7 and 3 is 21)
2. Now the common denominator is 21
change 3/7 to a fraction with 21 as denominator by multiplying the numerator to 3 and denominator also by 3 which will give you 3×3=9/ 7×3=21 or 9/21
note: you have to multiply both numerator and denominator by the same number which is used to convert the denominator to the number given by LCM.
3)Now change the second fractions denominator to 21 by multiplying the denominator 3 by 7 and numerator 2 to 7 :
2×7/3×7 = 14/21
4) Now the fractions have same denominator which means they can be added or subtracted.
5) Total amount of cherries he had= 9/21+14/21 = 23/21
6) The amount of cherries he ate = 1/4
7) Amount of cherries he has now with him after he ate 1/4 from 23/21 = 23/21 - 1/4
8) Again the fractions need to be changed to equivalent fractions inorder to subtract them.So,Take the LCM of the denominators (LCM 21 and 4 is 84).Now change the denominator of each fraction to 84.
9) 23/21 becomes 23× 4/21×4 = 92/84
1/4 becomes 1×21/4×21 = 21/84
now subtract them
92/84 - 21/84 = 71/84
71/84 cannot be properly divided so, 71/84 is the answer.
He has 71/84 pounds of cherries with him.

Ravi owns a plot of rectangular shape. He has fenced it with a length of 750ft.The length of the plot exceeds the breadth by 5ft.To find
The length and breadth of the plot ?So, according to the question
We have,
The length of fenced wire is 750ft.Let's assume
Breadth of plot = x.Length of plot = l.Length of fenced wire = WHe fenced this plot with a wire. So we can say this wire length is a perimeter of this plot of rectangular shape.
In mathematical form
2 (length + breadth) = length of fenced wire
2 ( l + x) = W -------------------(1)
From question
the length of the plot = breadth + 5ft.l = x +5 ------------------(2)
Now, putting the value of equation (2) and W in equation (1)
Then, we get
2 ( l + x) = W -------------------(1)
2 [( x + 5) + x] = 750
2 [ x + 5 + x] = 750/2
[ 2x + 5] = 375
2x = 375-5
2x = 370
x = 370/2
x = 185ft
Now, putting the value of x in equation (2)
Then, we get
l = x +5 ------------------(2)
l = 185 +5
l = 190ft
Length of this rectangular shaped plot = 190ft, andBreadth of this rectangular shaped plot = 185ft.

2y-10=6x
plz help me
Answer: simplifying
Step-by-step explanation:
2y + -10 = 6x
Reorder the terms:
-10 + 2y = 6x
Solving
-10 + 2y = 6x
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '10' to each side of the equation.
-10 + 10 + 2y = 10 + 6x
Combine like terms: -10 + 10 = 0
0 + 2y = 10 + 6x
2y = 10 + 6x
Divide each side by '2'.
y = 5 + 3x
Simplifying
