Step-by-step explanation:
Tom bought a bag full of coal. After one week the bag was 2|3 full. During the next week he used of the remaining coal What fraction was left in the bag?
Answer:
None
Step-by-step explanation:
When he first bought the coal, it was full. After one week, he used 1/3, leaving the bag 2/3 full. If he used the remaining coal in the bag, that means he used all of the coal - all two thirds of it.
The fraction of coal left in the bag was zero or none since Tom used the remaining coal.
What is the reasoning?The procedure of utilizing logical reasoning to analyze a condition to determine the best problem-solving approach for a particular issue, then using this approach to create and explain a resolution.
The reasoning is a tricky but interesting problem in mathematics that requires relations of variables to solve.
As per the given,
After one week the bag was 2|3 full
Now remaining coal = 1 -2/3 = 1/3 part
Now, Tom used this remaining amount.
So, 1/3 - 1/3 = 0 part.
Hence "The fraction of coal left in the bag was zero or none since Tom used the remaining coal".

Why are most streets designed in a way that they are perpendicular or parallel to each other? ...
The simple reason why streets are usually designed parallel or perpendicular to each other is because that pattern makes it easy for users to connect people easily.
What is meant by perpendicular and parallel streets?A perpendicular street can simply be defined as a street which intersect another streets. However, on the other end, two streets are said to be parallel to each other when they are in the same distance apart. The same is applicable in mathematics as a perpendicular line intercept another line and parallel lines don't meet.
That being said, when streets are parallel or perpendicularly designed, residents of the environment find it easy to communicate with each other. Business owners use this easy accessibility to easily describe their addresses to customers.

Explanation:
To convert from percent to decimal, we move the decimal point 2 spots to the left.
12.4% converts to the decimal form 0.124
Optionally you could use your calculator to say 12.4/100 = 0.124
--------
To convert from a terminating decimal to a fraction, we write the decimal digits over some power of 10. In this case, we write the "124" over 10^3 aka 1000. We write it over 1000 since the '4' is in the thousandths place value. Then reduce as much as possible.
124/1000 = (31*4)/(250*4) = 31/250 is the simplified fraction form
Use your calculator to see that 31/250 = 0.124 to confirm the answer.

How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
As per the given,
Let's say the cost per pound of strawberry taffy is "s" and the cost per pound of banana taffy is "b".
Then, the cost of 8 pounds of strawberry taffy and 3 pounds of banana taffy will be,
8s + 3b = 66
And,
The cost of 10 pounds of strawberry taffy and 3 pounds of banana taffy will be,
10s + 3b = 78

Warren has 40 coins (all nickels, dimes, and quarters) worth $4.05. He has 7 more nickels than dimes. How many quarters does Warren have?
Please provide a detailed explanation and steps on how to do
If he has 7 more nickels than dimes. The number of quarters that Warren have is 7.
How to determine the number of quarters?Let coins be:
n + d + q = 40
Where;
n = nickels
d =dimes
q = quarters
Hence,
.05n + .10d + .25q = 4.05
n = d + 7
Substitute (d+7) for n
(d+7) + d + q = 40
2d + q = 40 - 7
2d + q = 33
q = (33-2d)
So,
.05(d+7) + .10d + .25q = 4.05
.05d + .35 + .10d + .25q = 4.05
15d + .25q = 4.05 - .35
.15d + .25d = 3.70
Substitute (33-2d) for q
.15d + .25(33-2d) = 3.70
.15d + 8.25 - .5d = 3.70
.15d -.5d = 3.70 - 8.25
-.35d = -4.55
Divide both side by -/35d
d = -4.55 / -.35
d = 13 dimes
Nickels
n = d+7 where d is 13
n = 13 + 7
n = 20 nickels
Quarters
q = (33-2d)
q = 33 - 2(13)
q = 33 - 26
q = 7 quarters
Therefore 7 is the quarters.

then take the 35 dollars he already saved and put it into an equation as shown

the f(7) is just another way to say y=10(7) (f(x) is just y but fancy lol)
7 is the number of weeks he can work to get 105. It can't be 6 because that would be 95 dollars and it can technically be 8 but the question ask for the least number of weeks.

What are the missing segment lengths shown in the image?
The length of the missing ,line segments show in the image are AC = CD = 10√2 and AB = BC = 10 .
In the question ,
a figure is given , we have to find the length of the missing line segments .
From the given figure
the Δ ACD is a right triangle ,
given that ∠A and ∠D are equal
so , their corresponding length AC and CD will be equal , that is AC = CD
So , By Pythagoras Theorem
AC² + CD² = AD²
2*AC² = AD²
2*AC² = (20)²
2*AC² = 400
AC² = 400/2 = 200
AC = √200
AC = CD = 10√2
The triangle ABC is also right triangle
and ∠A and ∠C are equal
so , their corresponding length AB and BC will be equal , that is AB = BC
So , By Pythagoras Theorem
AB + BC = AC
2*AB² = AC²
2*AB² = (10√2)²
2*AB² = 200
AB² = 200/2 = 100
AB = √100
AB = 10 = BC

AB and CD are parallel lines, and PQ and PR are transversals which intersect AB at P and CD at Q and R. Angle APQ is labeled as 64 degrees, angle QPR is equal to x, angle PRD is equal to 110 degrees.
A) The value of the measure of angle x is; x = 55 degrees.
B) The way we got x is that the Internal angle between 2 parallel lines are equal and also that the three angles APO, x and BPR form a straight line and they sum up to 180 degrees.
What is the measure of the missing angles?A) From the given image attached, we see that the angle RPB can be calculated as;
m∠RPB = 180 - 120 = 60 degrees.
This is because sum of angles on a straight line sums up to 180 degrees.
Now, by definition of alternate angles, we can say that angle BPR is equal to 60 degrees.
Thus, the value of angle x is;
x = 180 - 60 - 65
x = 55 degrees.
B) From the given diagram, we can say that;
m ∠RPB + m < PRD = 180 degrees
This is because Internal angle between 2 parallel lines are equal.
Secondly the three angles APO, x and BPR form a straight line and they sum up to 180 degrees.

What is the Side Angle Side theorem?The two triangles are congruent if the two sides of one triangle are equal to the two sides of another triangle and the angles formed by the two sides of each triangle are equal. The "Side-Angle-Side" triangle congruence theorem is referred to as the SAS Criterion.The Side-Angle-Side theorem of congruency states that, if two sides and the angle formed by these two sides are equal to two sides and the included angle of another triangle, then these triangles are said to be congruent.Verification:
Let's perform an activity to show the proof of SAS. Given: AB=PQ, BC=QR, and ∠B=∠Q. To prove: ΔABC ≅ ΔPQRPlacing the triangle ABC over triangle QPR will cause B to fall on Q and the AB side to coincide with the PQ side.Point A falls on point P because of AB=PQ.The side BC will fall along the side QR since B=Q.Point C is in line with point R since BC=QR. As a result, BC and QR coincide, while AC and PR coincide.ABC will therefore match QPR. Consequently, ABCPQR. This exemplifies the SAS congruence criterion.Solution
From SAS
XY=QP and YZ=QR
therefore ∠Y = ∠Q
since the interior angles of the triangle are supplementary
∠Y + ∠X +∠Z = 180
∠Y + 22 + 36 = 180
∠Y = 180 - 58 = 122
therefore, ∠Q is also equal to 122
and (4w+ 14) =122
122 - 14 = 4w
108 = 4w
w = 108/4 = 27
Hence, from the SAS criterion
w is equal to 27

We have been given the following parameters;
The two lines a and b are parallel to each other.
Therefore, Angle (5x - 7) and Angle (3x + 17) are the same because of alternate interior angles.
Thus, (5x - 7) = (3x + 17)
Solving;
(5x - 7) = (3x + 17)
5x - 3x = 17 + 7
2x = 28
x = 14
Now, we can see that Angle (5x - 7) and Angle (4y + 3) makes linear pairs on line A.
Thus, (5x - 7) + (4y + 3) = 180
Substitute x = 14
(5(14) - 7) + (4y + 3) = 180
70 - 7 + 4y + 3 = 180
