Answer:
Introduction. Percent, p%
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100.
8.5% = 8.5/100 = 8.5 ÷ 100 = 0.085.
100% = 100/100 = 100 ÷ 100 = 1.
Increase the number by 8.5% of its value.
Percentage increase = 8.5% × 15,837.77
New value =
15,837.77 + Percentage increase =
15,837.77 + (8.5% × 15,837.77) =
15,837.77 + 8.5% × 15,837.77 =
(1 + 8.5%) × 15,837.77 =
(100% + 8.5%) × 15,837.77 =
108.5% × 15,837.77 =
108.5 ÷ 100 × 15,837.77 =
108.5 × 15,837.77 ÷ 100 =
1,718,398.045 ÷ 100 =
17,183.98045 ≈
17,183.98
Calculate absolute change (actual difference)
Absolute change (actual difference) =
New value - 15,837.77 =
17,183.98045 - 15,837.77 =
1,346.21045 ≈
1,346.21
Proof.
Calculate percentage increase:
Percentage increase =
8.5% × 15,837.77 =
8.5 ÷ 100 × 15,837.77 =
8.5 × 15,837.77 ÷ 100 =
134,621.045 ÷ 100 =
1,346.21045 ≈

Write the value of π correct to 5 decimal places.
Answer:
3.14159
Step-by-step explanation:
The value of π correct to 5 decimal places is 3.14159.
What are Decimal Numbers?Decimal numbers are numbers which includes a whole number part and a fractional part.
The point separating both parts is the decimal point.
Pi, which is written as the Greek symbol π, is defined as the ratio of the circumference of any circle to the diameter of that circle.
We know that,
Circumference of a circle, C = 2 π r, where r is the radius.
2r will be the diameter.
π = C / 2r
The value of pi to 5 decimal places = 3.14159
Normally we use 3.14.
Hence the value of pi is 3.14159 to 5 decimal places.

Pls halp
The average rate of change of f(x) on the interval [1,1+h] is [1/(h + 6) - 1/6]/h
How to find the average rate of change of f(x) on the interval [1,1+h]?The function is given as
f(x) = 1/(x + 5)
The interval is given as
[1, 1 + h]
Calculate f(1) as follows
So, we have
f(1) = 1/(1 + 5)
f(1) = 1/6
Calculate f(1 + h) as follows
So, we have
f(1 + h) = 1/(1 + h + 5)
f(1 + h) = 1/(h + 6)
The average rate of change of f(x) on the interval [1,1+h] is then calculated as
Rate = [f(1 + h) - f(1)]/[1 + h - 1]
This gives
Rate = [1/(h + 6) - 1/6]/h
Hence, the average rate of change of f(x) on the interval [1,1+h] is [1/(h + 6) - 1/6]/h

CRAFT FAIR Kylie is going to try to sell two of her oil paintings at the local craft fair. She is hoping to earn at least $400.
a. Write the inequality that represents the constraint of the situation, where x is the price of the first oil painting, and y is the price of the second.
b. Graph the inequality that represents the constraint on the sale.
The inequality that represents the constraint of the situation is x+y ≥ 400.
Inequality is defined as the mathematical expression in which both sides are not equal .
In inequalities the two vales are compared by "≤" , "≥" , "≠" .
For Example : 2x+3y≥4 is an example of inequality .
In the given question
Part (a)
Given Kylie sell first oil painting in $x

Kylie is trying to earn at least $400.
the term at least means she can earn $400 or greater than $400, so ≥ sign will be used,
According to the question
we get , x+y ≥ 400
So , x+y ≥ 400, is the inequality that represents the constraint of the situation.
Part (b)
The Graph of the inequality x+y ≥ 400 that represents the constraint on the sale is shown below .
Therefore , the inequality that represents the constraint of the situation is x+y ≥ 400.

A stationery shop orders a batch of pens from a factory. The factory could make the batch of pens in 20 days using 12 machines. Due to a fault, only 9 machines were used for the first 8 days. All 12 machines were used from day 9 onwards. Work out the total number of days taken to make the batch of pens.
The number of days taken to complete the production of a batch of pens are 22, as calculated by basic algebra.
What is basic algebra?Numbers, variables, constants, expressions, equations, linear equations, and quadratic equations are all part of the basics of algebra. Additionally, the algebraic expressions contain the basic arithmetic operations of addition, subtraction, multiplication, and division.
Now, According to the question, the factories used all 12 machines in the last days, Also, for the first 8 days, only 9 machines were in use.
Thus, If the factories used all 12 machines, the batch of pens took 20 days to be manufactured.
Hence, the equation formed from the given information by basic algebra is: 20 + 12 - 9(8) / 12
28 - (72/12)
=28 - 6 = 22

What is the difference between -21 and -8?
Answer:
-13
Step-by-step explanation:
(-21) - (-8) = -13
-21 - -8 = -13
Because of the two subtract signs next to each other before the number 8, they change to an addition sign.
From -21, move right 8 places along the number line because it is add 8.
-21 -20 -19 -18 -17 -16 -15 -14 -13

Rhiannon and Sophie both started saving for a new piano this month. Rhiannon will deposit $35.80 per week, but her bank account is currently overdrawn with a -$253.50 balance. Sophie also has a negative bank account balance of -$78.25 and will deposit $23.30 each week. How many weeks (w) will it take for the two bank accounts to have the same balance?
It will take 14.02 weeks for both the accounts to have the same balance
Bank account balance of Rhiannon = -$253.50
Money deposited by Rhiannon in the bank account each week = $35.80
Bank account balance of Sophie = -$78.25
Money deposited by Sophie in the bank account each week = $23.30
Let the number of weeks it takes to have the same account balance be x, therefore formulating the algebric equation we get:
Bank balance of Rhiannon + Money deposited by her each week*No of weeks it will take for the balance to be equal = Bank balance of Sophie + Money deposited by her each week*No of weeks it will take for the balance to be equal
= -253.5 + 35.8(x) = -78.25 + 23.3(x)
= -175.25 = -12.5(x)
x = 14.02 weeks
Therefore, it will take 14.02 weeks for both the accounts to have the same balance

The fixed cost for producing the game = $4300
Let the total cost be denoted by C.
And let x be the number of games produced.
a) Total cost = variable cost + fixed cost
C = $0.50x + $4300
b) Average cost = total cost/number of games produced
