A phone company has two long distance plans. Plan A charges a flat monthly fee of $13 and $0.37 per minute of long distance calls Plan B charges a flat monthly fee of $28 and $0.15 per minute of long distance calls. After how much time on long distance calls to the nearest minute, would the cost of plan A be equal to the cost of plan B?
Answer:
68.18minStep-by-step explanation:
let the cost of plan A be Y1
and the cost of plan B be Y2
let the number of minutes for both plans be x
let us model the cost of plan A
Y1= 13+0.37x-------1
let us model the cost of plan B
Y2= 28+0.15x------2
when Y1=Y2, we can now solve for x which is in minutes
13+0.37x=28+0.15x
collect like terms
13-28=0.15x-0.37x
-15=-0.22x
divide both sides by -0.22
x=-15/-0.22
x=68.18min

Benito and Tyler are painting opposite sides of the same fence. Tyler has already painted 19 ½ feet of his side of the fence when Benito starts painting. Part A: How long will it take for the two sides of the fence to have an equal number of feet painted? 80 minutes How many feet will be painted on Benito's side of the fence when the two sides have an equal number of feet painted? 45 feet Part B: Tyler claims that because he started painting first, he will finish painting his side of the fence before Benito finishes painting his side. Is this true? Explain. Part C: The painter who finishes first gets to rest while the other painter finishes. How long will the painter who finishes first get to rest? Explain.
Answer:
Part A: The time it will take for both of them to painted equal number of feet is 4.875 minutes
The number of feet Benito will have painted when the two sides have equal length is 73.125 feet
Part B: It is not true that Tyler will finish painting his side of the fence before Benito finishes painting his
Part C: Time to rest is 1.864 minutes
Step-by-step explanation:
The given information are;
The length of fence Tyler already painted when Benito started = 19 ¹/₂ feet
Benito paints 15 feet/minute
Tyler paints 11 feet/minute
Length of fence = 150 feet
Part A:
The time it will take for both of them to painted equal number of feet is given as follows;
11×t + 19.5 = 15×t
4×t = 19.5
t = 19.5/4= 4.875 minutes
The time it will take for both of them to painted equal number of feet = 4.875 minutes
The length Benito will have painted when the two sides have equal length = 15 × 4.875 = 73.125 feet
Part B: The time it will take Tyler to finish painting his side of the fence is given as follows;
11 × t + 19.5 = 150
t = (150 - 19.5)/11 ≈ 11.864 minutes
While the time it will take Benito to finish painting his side of the fence is given as follows;
15 × t = 150
t = 150/15 ≈ 10 minutes
Therefore it is not true that Tyler will finish painting his side of the fence before Benito finishes painting his
Part C: Given that Benito finishes before Tyler, the length of time Benito gets to rest is given as follows;
Time to rest = Time Tyler takes to finish - Time Benito takes to finish
Time to rest = 11.864 - 10 = 1.864 minutes.
A sweater is on sale for $34.15 . If the markdown on the sweater is 45% off , what was the original cost for the sweater ? pls help me .
The complete cost of purchasing an asset is known as the original cost.The whole costs associated with purchasing and using an asset are taken into account when calculating its initial cost.
Find original cost ?Subtract the asset's cost from its salvage value (what you anticipate it to be worth at the end of its useful life) to determine depreciation using the straight-line technique.The amount that can be depreciated, or the depreciable basis, is the outcome.Subtract this sum from the asset's useful life, which is measured in years. Revenue less costs equals profit.Markup is calculated as follows: markup = 100 * (revenue - cost) / cost.And finally, use revenue = cost + cost * markup / 100 if you need to know the selling price. The gross profit of a unit, which is its sales price less its cost to produce or acquire for resale, is divided by the unit's cost to determine the markup %.The markup percentage, which is computed as (12 - 8) / 8, is 50% for an item that costs the business $8 to produce but is priced at $12.Original cost = $ 34.15 - $ 0.45/ 100
= 0.33%

Anne has $5000 in her savings account and decides to leave there for three years. After one year the account increases by 10%, the following year it decreases by 5% and in the third year it increase by 15%. How much is in the account after three years?
Answer:
$6000
increases by 10% but you then take away 5% fron the 10 as it decreases by 5. meaning you have incresed by 5% and adding the 15% equals 20%. so the account increases by 20%. 20% of 5000 equals 1000. add the two together and you get 6000. so the account total now is $6000

Answer:
[tex]Math\ Book = 3\frac{65}{72}\ kg[/tex]
Step-by-step explanation:
Given
[tex]Backpack = 18\frac{7}{9}kg[/tex] --- with math book
[tex]Backpack = 14\frac{7}{8}kg[/tex] --- without math book
Required
Determine the weight of her math book
To do this, we simply calculate the difference in the weights given.
Math Book= Backpack(with math book) - Backpack (without math book)
[tex]Math\ Book = 18\frac{7}{9} - 14\frac{7}{8}[/tex]
[tex]Math\ Book = \frac{169}{9} - \frac{119}{8}[/tex]

3 =2b -3 can someone help me understand this
Answer:
Step-by-step explanation:
Answer: 3=b
Step-by-step explanation:
First get the like terms 3 and (-3) on one side.
You do this by either adding or subracting, it depends on the sign of the number. -3 is negative 3 but you have to add it to make it zero and on the other side you add it and get 6.
Then you divide 6 by 2. 2b by 2 to get the variable alone and 3=b is your answer.

One factor of a polynomial p(x) is (x + 7).

The required value of function p(x) at x = -7, p(-7) is zero.
What are functions?Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
here,
As given that one factor of a polynomial p(x) is (x + 7).,
Since factor x, + 7 also represents one of the zeros of a polynomial function p(x).
So, when one put the value x = -7 in the function, the function gives zero in the outcome.
Thus, the required value of function p(x) at x = -7, p(-7) is zero.

What is quadratic and not quadratic?
Answer:
Step-by-step explanation:
A quadratic equation must contain
an [tex]x^{2}[/tex] term
and must not contain terms with degrees higher than [tex]x^{2}[/tex].
A non/not quadratic equation doesn't have an [tex]x^{2}[/tex] term. It also features a term such as [tex]x^{3}[/tex] which isn't allowed in quadratic equations
Answer:
A quadratic equation contains a quadratic term (x²), as per the name. The quadratic term must be any variable squared. A non-quadratic equation is an equation that does not contain a quadratic term such as x².
The format for a quadratic equation should look like so: ax² + bx + c = 0, in which a, b, and c are all real numbers and a cannot be equivalent to 0. An example of a quadratic could be: 5x² + (-3x) + 5 = 0.
An example of a non-quadratic equation could be: x³ - 81 = 0.
