Jamir bought p pencils that cost $0.10 each and F folders that cost $.35 each. A 8.75% sales tax will be applied to the total cost.
PART ONE:
Which expression repersents the total amount Jamir paid,including tax? Write the letter of the correct answer on the line below.
a) 0.0875 (p + f) + 0.0875 (0.10p+0.35f)
b) (0.10p + 0.35f) + 0.0875 (0.10p+0.35P)
c) 0.35(0.0875f) + 0.10(0.0875p)
d) 0.35(1.0875f) + 0.10(1.0875f)
Answer=
PART B
Explain why each of the other answers are worng.
LAST PART
Jamir purchased a dozen pencils and 8 folders. How much did he spend in all,after all tax was applied? Show your work please
Answer$=
Answer:
b) (0.10p + 0.35f) + 0.0875 (0.10p+0.35P)
first is Jamir total cost + the sales tax of 0.0875 of the total cost
a. this is wrong because both is the sales tax only, theres no total cost include
c. wrong because its just also sales tax only
d. wrong because the total cost must only multiplied by the sales tax
PART B
12(0.10) + 8(0.35)
= 1.2 + 2.8
= $4 as the total cost
4(1.035)
= $4.14 as after tax bill

Prove that every point on the perpendicular bisestor of a segment is equidistant from the endpoint of segment​.
Every point on the perpendicular bisector of a segment is equidistant from the endpoint is hence proved
The line segment AB and let MN is the perpendicular bisector of AB line segment.
we prove the required result by congruence of triangles.
Two triangles are said to be congruent if all three corresponding sides are equal and all the three corresponding angles are equal in measure
From the figure,
Let P be any point on the perpendicular bisector MN. Join A to P and B to P.
To show AP=BP
In ΔANP and ΔBNP
PN=PN {common side in both triangles }
∠PNA=PNB=90°{ MN is ⊥ bisector of AB}
AN=NB {N is mid point}
By SAS rule of congruent ΔANP≅BNP
By CPCT (corresponding Parts of congruent triangles)
AP=BP
But P is point on MN
Therefore, every point on the perpendicular bisector of line segment AB is equidistant from the segments endpoints.
Hence Proved.

how much work is done raising an 8 lb mass to a height of 18 ft above the ground? (use decimal notation. give your answer as an exact number.)
Therefore, the work done in this problem comes out to be 144 ft pound.
Where is the work done?The work a force does is calculated as the product of the object's displacement and the components of the applied force of the object in the displacement direction. Pushing a block with some force and accelerating the body results in work being completed.
Here,
Given : an 8 lb mass
a height = 18ft
So, we find the work done
Using formula
=> Work done = m*g*h
=> Work done = weight * height
=> Work done = 8*18
=> Work done=144 ft pound
Therefore, the work done in this problem comes out to be 144 ft pound.

The use of algebra in everyday life.
Algebra is a branch of mathematics that uses numbers, symbols, or letters to solve math problems. In everyday life, algebra is often used for financial planning, traveling time calculation, and so on.
In the above problem, we can take some notes as follows:
Departure time (x) = 5:15 PM
Travel time (t) = 1 hour 20 minutes
Arrival time (y) = 25 minutes
If z is the playing time of the movie, then z can be expressed mathematically in the following way:
z = x + t + y
= 5:15 + 1 hour 20 minutes + 25 minutes
= 6:60 PM or generally written 7:00 PM

A pair of positive integers a and b is such that their greatest common divisor is 5 and their least common multiple is 55. Find the smallest possible value of a+b.
Answer:
Step-by-step explanation:
The greatest common divisor of two integers a and b is a divisor common to both integers that is greater than any other common divisor. The least common multiple of two integers a and b is the smallest positive integer that is a multiple of both a and b.
To find the smallest possible value of a+b, we can start by trying to find the smallest possible values of a and b that satisfy the given conditions.
Since the greatest common divisor of a and b is 5, we know that both a and b must be divisible by 5. We can write a = 5x and b = 5y, where x and y are positive integers.
The least common multiple of a and b is 55, so we know that both a and b must be factors of 55. We can write 55 as the product of its prime factors: 55 = 5 * 11. Since a is divisible by 5, we know that a must be equal to 5 or 25. Similarly, since b is divisible by 5, we know that b must be equal to 5 or 25.
There are four possible pairs of values for a and b: (5,5), (5,25), (25,5), and (25,25). The smallest of these is (5,5), which gives us a+b = 5+5 = 10. Therefore, the smallest possible value of a+b is 10.

a local civic theatre has 22 seats in the first row and 21 rows in all. each successive row contains 3 additional seats. how many seats are in the civic theatre
Using the arithmetic progression, If a theatre has 30 rows of seats there are 22 seats in the first row,21 in the second row, 51 in the third row, then the total number of people that the theatre hold is 2400
The total number of rows = 51
Number of seats in the first row = 22
Number of seats in the second row = 21
Number of seats in the third row = 51
Common difference= Second term - first term
= 26-22
= 4
The given sequence is in arithmetic progression
Substitute the values in the equation
= 15[44+29×4]
= 15[44+116]
= 15×160
= 2400
Hence, using the arithmetic progression, if a theatre has 51 rows of seats and there are 22 seats in the first row,21 in the second row, 51 in the third row, then the total number of people that the theatre hold is 2400

Tamba jut received a bonu which increaed hi dipoable income by $860. If Tamba' marginal propenity to conume (mpc) i 0. 75, hi conumption rie by _______
The formula for calculating the change in consumption is MPC x Change in Disposable Income.Thus, Tamba's change in consumption = 0.75 x $860 = $645
The marginal propensity to consume (MPC) is a measure of the proportion of an increase in disposable income that is spent on consumption. In Tamba's case, his MPC is 0.75, which means that for every $1 increase in his disposable income, he will spend 75 cents on consumption. The formula for calculating the change in consumption is MPC x Change in Disposable Income. Therefore, when Tamba's disposable income increased by $860, his consumption increased by 0.75 x $860 = $645.

What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.
Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.
The internal angles ∠A is 33° and ∠B is 117°.
Then the measure of the internal angle ∠C is given as,
∠A + ∠B + ∠C = 180°
33° + 117° + ∠C = 180°
∠C = 30°
The angle ∠C and angle ∠ACD are supplementary angles. Then we have
