The amount of waste is 22 oz
How to determine the waste amount?The weights of the 3 rainbow trouts are:
3 Ib 5 oz, 2 Ib 12 oz, and 3 Ib 8 oz.
The total weight is:
Total = 3 Ib 5 oz + 2 Ib 12 oz + 3 Ib 8 oz
Evaluate the sum
Total = 8 Ib 25 oz
The amount she was left with is 8 Ib 2 oz
Subtract this amount from the total
Waste = 8 Ib 25 oz - 8 Ib 2 oz
Evaluate
Waste = 22 oz
Hence, the amount of waste is 22 oz

In construction, the precision used to build a structure directly influences the strength of the structure. In the Rocky Mountains, many houses’ roofs are built using trusses, which are strong enough to support the heavy load from snow, but light enough to build in a stockyard and transport to the construction site. Chris works in the stockyard. He has been told he needs to build a series of trusses for a new house using the pattern below. He has also been told the pattern may be inaccurate—so he needs to check and make sure the following features are all parallel, and adjust the pattern before starting.
On this discussion board, post your answers to these questions:
1) What method(s) can Chris use to make sure the segments in the pattern are all parallel and that his new trusses are built precisely and strongly?
2) What method(s) can Chris’s boss use to verify the precision of the trusses Chris builds?
3)Identify any alternate interior angles, corresponding angles, and/or alternate exterior angles.
The method that Chris can use to make sure the segments in the pattern are all parallel is to treat AI as a single line that acts as a transversal for the lines that need to be parallel.
How to illustrate the information?Within the set of lines which need to be parallel, the acute angles must be congruent.
Both angles CDE and EDF need to be 180° minus twice the measure of one of the congruent acute angles.
The pair of the acute angles previously within each of the two sets of parallel lines are corresponding.
The fact that the transversals go through endpoints, there are no alternate angles, interior or exterior because alternate angles are on opposite sides of the transversal.

what is the solution to the system of equations: 4x-y=10 and x-4=y
Answer:
(2, - 2 )
Step-by-step explanation:
4x - y = 10 → (1)
x - 4 = y → (2)
substitute x - 4 = y into (1)
4x - (x - 4) = 10 ← distribute parenthesis on left side by - 1
4x - x + 4 = 10
3x + 4 = 10 ( subtract 4 from both sides )
3x = 6 ( divide both sides by 3 )
x = 2
substitute x = 2 into either of the 2 equations and solve for y
substituting into (2)
2 - 4 = y
- 2 = y
solution is (2, - 2 )
Answer:
x = 2 , y = -2
Step-by-step explanation:
I will use the elimination method :
4x-y = 10 - Equation Number 1
x-4 = y - Equation Number 2
For the second equation we add 4 to both sides and subtract y from both sides :
x = y + 4
x - y = 4 - Let's call this equation number 3 :
Now we can subtract the equation 1 with 3 to eliminate y :
3x = 6
x = 2
Now we substitute this value into equation 2 to solve for y :
(2)-4 = y
y = -2
Substitute these values into equation 1 to verify :
4(2) - (-2) = 10
8 + 2 = 10
10 = 10
So these values must be correct

Five times a number decreased by nine is equal to twice the number increased by 23. which equation could be used to solve the problem? 5x – 9 = x 23 5x – 9 = 2x 23 5x 23 2x = 23 5x 23 = 2x 23
Answer:
Step-by-step explanation:
5x-9 = 2(x+23) or 5x-9 = 2x+46
Let' x be the "number."
"Five times a number decreased by nine" means: 5x - 9
"equal to twice the number increased by 23" means: = 2(x+23)
Put them together: 5x-9 = 2(x+23)
5x-9 = 2(x+23)
5x-9 = 2x+46

The probability that a student takes art, given that the student takes music is 10.8%
In probability, we say two events are independent if knowing one event occurred doesn't change the probability of the other event.
For example, the probability that a fair coin shows "heads" after being flipped is 1/21/21, slash, 2. What if we knew the day was Tuesday? Does this change the probability of getting "heads?" Of course not. The probability of getting "heads," given that it's a Tuesday, is still 1/21/21, slash, 2. So the result of a coin flip and the day being Tuesday are independent events; knowing it was a Tuesday didn't change the probability of getting "heads."
Two events, A and B, are independent if
P(A ∣ B)=P(A)
P(A).P(B) = P(A ∩ B)
In the given question there are independent events.
Given:-
P(A) = Student takes both art and music = 0.9
P(B) = Student takes music = 0.12
P(A ∩ B) = student takes art, given that the student takes music
Thus by using the formula we get,
P(A ∩ B) = 0.9 x 0.12 = 0.108 = 10.8%
The probability that a student takes art, given that the student takes music is 10.8%

A flagpole casts a shadow 22 feet long. If a man 6 feet tall cast a shadow 4.3 feet long at the same time, how tall is the flagpole? Please explain your answer.
Answer:
30.70 ft
Step-by-step explanation:
For shadow problems, we make the assumption that an object's height and its shadow length are proportional.
SetupThe proportion for the two objects is ...
height/shadow = pole/(22 ft) = (6 ft)/(4.3 ft)
SolutionMultiplying by 22 ft, we find the pole height to be ...
pole = (22 ft)(6 ft)/4.3) ≈ 30.70 ft
The flagpole is about 30.70 feet tall.

If the machine can produce 280 inches of ribbon in 30 minutes, approximately
how many feet can it produce in an 8 hour work day?
O 328 feet
O 358 feet
O 373 feet
O 309 feet
Answer:
373 feet
Step-by-step explanation:
Since the rate of the machine producing ribbon is proportional to time, we can determine the number of inches of ribbon in 8 hours by some quick operations.
There are 16 1/2 hours in 8 hours, so we can multiply 280 by 16.
[tex]280 *16=4480[/tex]
Now, we have the number of inches it can produce in an 8-hour work day. However, we must convert to feet since that is the form of measurement the question is asking for. We can do so by dividing by 12.
[tex]4480/12=373.33[/tex]
Therefore, the number of feet the machine can produce in an 8-hour work day is 373.
#LearnWithBrainly
Step-by-step explanation:
the other answer is correct.
a few add-ons :
1 ft = 12 in
30 minutes = 1/2 hour (as every hour has 60 minutes)
every hour has therefore 2 half hours.
1 hour = 2 × 1/2 hour
8 hours = 8 × 2 × 1/2 hours = 16 × 1/2 hour
so, in 16 times the amount of time (8 hours) the machine can produce 16 times the amount of ribbon (16 × 280 in).
16 × 280 = 4480 in
and because every 12 in is 1 ft, this is then
4480/12 = 373.3333333... ft
therefore, 373 is the right answer (rounded).

9+10=21
Yes, my calculation says , it is possible.
But only in other number base.
Let me explain.
9 + 10 = 21
or, 19 = 21
Assume that , 19 is a decimal number.
and 21 is a n base number.
As 19 is equivalent to 21,
So 10 base 19 is equivalent to n base 21.
So with the help of math I can get that,
19 = 1 × 10^1 + 9× 10^0
21 = 2 ×n^1 + 1×n^0 = 2n + 1
So , 2n + 1 = 19
or, 2n = 18
or, n = 9
So finally, we can say that,
10 base 19 = 9 base 21
Thus 9+10=21 is possible
The reason why people sometimes assume that the calculation 9 + 10 = 21 is as explained below.
How to calculate in number bases?We want to find out the reason why people say that; 9 + 10 = 21
Now, the way you have explained it is one way to look at it by utilizing number bases to play around with the figures to arrive at 21.
However, another way is to use algebra trick pattern which is;
9 can be expressed as 3 * 3
Also, 10 can be expressed as 5 * 2. Thus, we now have;
(3 * 3) + (5 * 2)
The applying properties of algebra to cross multiply gives;
(3 * 2) + (5 * 3)
= 6 + 15
= 21
Now, though your explanation arrived at 21 and mine also 21, but those are not correct mathematical methods as 9 + 10 must be equal to 19 and not 21.

(a) Using Fermat's little theorem, show that 999 999 is divisible by 7.
(b) A number has digits that are all 9 and is divisible by 13. Show that
it is also divisible by 1001.
(a) Fermat's little theorem states that for any prime [tex]p[/tex], we have
[tex]a^{p-1} \equiv 1 \pmod p[/tex]
for any integer [tex]a[/tex]. Then
[tex]999,999 \equiv 1,000,000 - 1 \equiv 10^6 - 1 \equiv 1 - 1 \equiv 0 \pmod 7[/tex]
so 7 does indeed divide 999,999.
(b) Generalizing, we have
[tex]10^{12n} - 1 \equiv \underbrace{999\ldots999}_{12n \text{ nines}} \equiv (10^n)^{12} - 1 \equiv 0 \pmod {13}[/tex]
for positive integer [tex]n[/tex]. Now, since 1 = 1001 - 1000 and [tex]-1\equiv1000\pmod{1001}[/tex], it follows that [tex]10^3[/tex] is its own inverse modulo 1001, i.e.
[tex]10^3 x \equiv 1\pmod{1001} \implies x = 10^3[/tex]
This means
[tex]10^{12n} \equiv (10^3\times10^3)^{2n} \equiv 1^{2n} \equiv 1\pmod{1001} \\\\ \implies 10^{12n} - 1 \equiv 0 \pmod{1001}[/tex]
which is what we wanted to show.
