Timmy received $50 for his birthday. Following the birthday party, his parents promised him $5 each week for completing his chores. Assuming timmy completes all chores, use a linear equation to determine the number of dollars timmy will have 7 weeks after his birthday.
Assuming timmy completes all chores, the number of dollars timmy will have 7 weeks after his birthday is 85 dollars.
What are equations?In mathematics, an equation is a claim that two expressions are equivalent. It is a mathematical expression that employs the equals symbol, "=", to indicate that two quantities have values that are equal. Problems in algebra, geometry, calculus, and other branches of mathematics are frequently solved using equations. In algebra, equations are frequently used to depict the connection between variables and constants, as well as to discover the value of an unknown variable. For example, the equation x + 2 = 5 may be utilised to get the value of x, which is 3. Equations can be linear, quadratic, or higher-degree, and they can involve multiple variables.
How to solve?
Let x be the number of weeks after Timmy's birthday.
The total number of dollars Timmy will have after x weeks is 50 + 5x.
Therefore, Timmy will have 50 + 5(7) =85 dollars after 7 weeks

A department store buys 200 shirts at a cost of $2,400 and sells them at a selling price of $20 each. Find the percent markup.
If the store buys 200 shirts for $2400 and sells for $20 each then the percent markup is = 66.67% .
In the question ,
it is given that ,
the number of shirts that departmental store buys is = 200 shirts .
the cost price for 200 shirts is = 2400
So , the cost for 1 shirts is = 2400/200 = $12 ,
the selling price for 1 shirt is = $20 ,
the percent markup can be calculated using the formula ,
percent markup = (selling price - cost price)/(cost price) × 100 ,
= (20 - 12)/12 × 100
= 8/12 × 100
= 800/12
= 66.66666
≈ 66.67 % .
Therefore , percent markup is 66.67% .

A state seal, which is round, hangs in the capitol building. It has a radius of 2 yards. What is the seal's diameter?
Step-by-step explanation:
you do understand that the diameter of a circle is simply 2 times the radius, yes ?
imagine a circle and you draw a radius line (from the center of the circle to the circle arc).
and now imagine to draw another radius line, just in the opposite direction.
when you look at the result, you have 1 straight line going from the circle arc to the circle arc and passing through the center of the circle. that is what a diameter is.
how long is it ? well, we drew 2 radius lines to create this line. so, it is 2×radius long.
so, the diameter of the seal is
2×2 = 4 yards

What is line equation?
For a line equation for the form of y=m x+b, the slope is m. m=7
The first step to answering this question is to find the slope of the first line. To do that, we need to put it in slope-intercept form.
y=7x+5 => y=7x+5
So the slope of this line is 7. Perpendicular lines have a negative reciprocal slope, so the slope of the perpendicular line is 7. Using that and the point (1,3) we can make an equation for the line in point-slope form: We can then convert this into slope intercept form.
=> y=7x+5

Find an explicit formula for the following equence, an which tart with a1=23. 23,34,45,56,…
The explicit formula for the given arithmetic sequence is aₙ = 23 + (n - 1)11. Here the first term is a1 = 23 and the common difference is d = 11.
What is the explicit formula for an arithmetic sequence?The explicit formula for an arithmetic sequence gives the nth term of the sequence. I.e.,
aₙ = a1 + (n - 1)d
Here a1 is the first term; d is a common difference, it is calculated by
d = aₙ₊₁ - aₙ = aₙ₋₁ - aₙ
Calculation:The given sequence is 23, 34, 45, 56,...
Here the first term a1 = 23
So, the common difference between the terms in the sequence is
d = 34 - 23 = 11
Then, the explicit formula for the given sequence is
aₙ = a1 + (n - 1)d
⇒ aₙ = 23 + (n - 1)11
Therefore, the nth term of the explicit formula for the given arithmetic sequence is aₙ = 23 + (n - 1)11.

Based on the information given for cozy nights industries, what is the total cost of packaging each comforter?.
The required total cost of packaging each comforter is $89.20.
How to calculate the total cost of packaging each comforter?Activity estimated indirect activity costs allocation base estimated quantity of allocation base,
materials handling $ 12,600 number of parts 4,200 parts
Cost per part = $ 12,600/4,200 = $3
assembly$ 55,440 number of parts 4,200 parts,
Cost per part = $ 55,440/4,200 = $13.20
packaging $10,920 number of comforters 1,050 comforters each comforter consists of 4 parts
Cost per part =$10,920 /1,050 = $10.40
Then, For all cost of 4 parts,
Materials handling = ($3 x 4) = $12
Assembly = ($13.20 x 4) = $52.80
Packaging = ($10.40 x 1) = $10.40

the initial population of a town is 100,231 and it grows with a doubling time of 98 years. what will the population be in 31 years?
If the initial population of a town is 100,231 and it grows with a doubling time of 98 years, the population after 31 years is 124803
The initial population of the town = 100231 people
The doubling time = 98 years
We have to find the population in 31 year
The exponential function will be
f(t) = fo(2)^(t/98)
f(t) is the population of the town in t years
fo is the population of the town in t = 0 years
t is the number of years
2 because it doubling time
The value of t = 31 years
Substitute the values in the function
f(31) = 100231×(2)^(31/98)
Do the arithmetic operations
f(31) = 100231 × 1.245
f(31) = 124803.23

The circumference of a circle is 11π cm. What is the area, in square centimeters? Express your answer in terms of π.
Answer:
The area of the circle is 30.25π cm^2.
Step-by-step explanation:
The circumference of a circle is equal to the diameter of the circle times π. Therefore, if the circumference of the circle is 11π cm, the diameter must be 11 cm.
The formula for the area of a circle is A = πr^2, where r is the radius of the circle. The radius of the circle is half the diameter, so the radius is (1/2) * 11 cm = 5.5 cm.
Substituting this value for r into the formula for the area of a circle, we get:
A = π * (5.5 cm)^2
= π * 30.25 cm^2
= 30.25π cm^2
Therefore, the area of the circle is 30.25π cm^2.
