What is the minimum number of slices the bakery will have to cut the pie into in order for each slice to contain less than 22 grams of sugar ? Show your work. Part B: If the bakery cuts the pie into that minimum number of slices, how much sugar, in grams, will each slice of pumpkin pie contain? Round your answer to the nearest hundredth.
Answer:
9 slices20.85 gStep-by-step explanation:
You want the minimum number of pie slices and the amount of sugar in each such that the sugar in each slice is less than 22 grams when the whole pie has 187.64 grams of sugar.
A: SlicesThe sugar in each of n slices is 1/n times the sugar in the whole pie. You want ...
(187.64 g)/n < 22 g
Multiply by n/(22 g) to get
n > 187.64/22
n > 8.53
The smallest whole number that satisfies this inequality is n = 9.
The minimum number of pie slices is 9.
B: SugarWhen the sugar in the pie is divided into 9 equal parts, each part is ...
(187.64 g)/(9 slices) = 20.85 g/slice
Each slice of pumpkin pie will contain about 20.85 grams of sugar.

The constant of proportionality in the equation c = 8m is 8.
What is a variation?A variation is a relation between a set of values of one variable and a set of values of other variables. Direct variation. In the equation y = mx + b, if m is a nonzero constant and b = 0, then you have the function y = mx (often written y = kx), which is called a direct variation.
since C = 8m is an equation and the relationship between c and m is direct.
It means that dividing both sides of the equation by m we have
C/m = 8m/m
c/m = 8
Therefore the constant of proportionality is 8
In conclusion the constant of proportionality for which c = 8m is 8.

What is combination?
A combination is a choice made in mathematics from a group of different elements when the order of the choices is irrelevant (unlike permutations). For instance, if three fruits, such as an apple, an orange, and a pear, are supplied, there are three possible pairings of the two: an apple and a pear. Formally speaking, a k-combination of a set S is a subset of S's k unique components. In other words, two combinations are the same if and only if they have the same members. (It is not important how the individuals in each set are arranged.) The quantity of k-combinations for a set with n components
Given, 9 of the 20 banners with the word “Hello” in different languages with the 9 countries
Toatl ways for arranging the 9 banners will be 9C2

At around noon the store roof appears to have stopped leaking, so an employee removes the bucket that was catching the water and does not replace it. Overnight it begins to rain again, and water starts leaking from the ceiling onto the floor, again creating a circular puddle. The hole in the roof is larger this time, so at each time, t, in minutes, the radius of the puddle increases by 0.25 cm. Write a composition of functions to represent the area of the puddle as a function of time.
S= 0.0625t² is the composition of a function to represent the area of the puddle as a function of time.
What is meant by area?The defined region represents the extent of the area on a plane or curved surface. The area of a planar region refers to the area of a shape or planar layer, while surface area refers to the area of an open surface or boundary of a three-dimensional object. Area can be defined as the amount of material of a certain thickness required to model the mold, or the amount of paint required to cover the surface in a single layer. This is a two-dimensional equivalent of the length of a curve or the volume of a solid..
We obtain the data from the equation.
The radius is increased by 0.25 Cm for each t min.
Assume that the puddle's area is S.
We all know that.
Circle area = πr²
So, S= πr²
S= π(0.25t)²
S= π0.0625t²
S= 0.0625πt²
Therefore, the area of the puddle is S= 0.0625πt²

A metallurgist has one alloy containing 35% titanium and another containing 52% titanium. How many pounds of each alloy must be use to make 45 pounds of a third alloy containing 47% titanium
Step-by-step explanation:
% in calculations are always represented as hundredths, as 100% represents the whole, and n% = n/100 of the whole.
x = pounds of 35% alloy.
y = pounds of 52% alloy.
x + y = 45
0.35x + 0.52y = 0.47(x + y)
from the first equation we get e.g.
x = 45 - y
now we use this in the second equation :
0.35(45 - y) + 0.52y = 0.47((45 - y) + y)
15.75 - 0.35y + 0.52y = 0.47(45 - y + y)
15.75 + 0.17y = 0.47×45 = 21.15
0.17y = 5.4
y = 5.4/0.17 = 31.76470588... pound
x = 45 - y = 13.23529412... pound

Give m || n, find the value of x.
The value of x, given the angles m and n can be found to be 30.
How to find the angles?Given the fact that m || n, it means that when m and n are added, they equate to 180 degrees.
The reason for this is that m and n are supplementary angles and such angles will always add up to 180 degrees.
This means the value of x can be found as:
180 = m + n
180 = (6x - 5 ) + ( x - 25 )
180 = 6x + x - 5 - 25
180 = 7x - 30

By the end of the year, 18 cans were sold. Calculate (A) the number of cans of soup ending inventory and (B) the cost of ending inventory under LIFO, FIFO, and weighted average. (Round your final answers to the nearest cent.)
A) The number of unsold cans of soup (ending inventory) is 19.
B) The various costs of the ending inventory under LIFO, FIFO, and the weighted average are as follows:
Ending Inventory
LIFO $17.15
FIFO $25.65
Weighted average $21.47
How are the inventory methods different?FIFO assumes that the physical flow of goods sold should follow the chronological sequence of purchases or production.
LIFO assumes that the first goods acquired are the last to be sold.
The Weighted Average uses an average to determine the cost of ending inventory and the cost of goods sold.
Description Units Unit Cost Total
Beginning inventory 12 $0.85 $10.20
Purchases 4 $0.95 $3.80
Purchases 6 $1.05 $6.30

Purchases 8 $1.50 $12.00
Total 37 $41.75
Sales 18
Ending inventory 19 (37 - 18)
Average cost = $1.13 ($41.75/37)
LIFO:
Ending inventory = $17.15 ($10.20 + $3.80 + 3 x $1.05)
Cost of goods sold = $24.60 ($41.75 - $17.15)
FIFO:
Ending inventory = $25.65 (4 x $1.05 + $9.45 + $12.00)
Cost of goods sold = $16.10 ($41.75 - $25.65)

What is a graph?A visual representation or diagram that represents data or values is known as a graph.
The function equations are provided as
f(x) = 1/3x+1
f(x) - 1 = 1/3x
g(x) = 1/3(6x) + 1

The solution for A(3) in the function when the function A(x) = 4 − (x + 3)⁵ is -772
How to determine the solution for A(x) in the function?From the question, we have the following equation that can be used in our computation:
A ( x ) = 4 − ( x + 3 )^5
To make the equation legible, we need to rewrite it
So, we have the following representation
A(x) = 4 − (x + 3)⁵
Also from the question, we have
A(3)
This means that the value of x is 3, and we calculate A(x) when x = 3
Substitute the known values in the above equation, so, we have the following representation
A(3) = 4 − (x + 3)⁵
So, we have the following equation
A(3) = 4 − (3 + 3)⁵
There are constants to add or subtract to both sides of the equation
However, there is no factor to multiply or divide from both sides of the equation
So, we have the following representation
A(3) = 4 − (6)⁵
Solving further, we have

The population of a country was 64 million in 1993 and the continuous exponential growth rate was
estimated at 2.7% per year. Assuming that the population of the country continues to follow an
exponential growth model, find the projected population in 2008. Round your answer to 1 decimal
place.
The approximate population in 2008 is
million people
Answer: 104.1
Step-by-step explanation:
If [tex]P(t)[/tex] represents the initial population in millions. [tex]t[/tex] years after 1990, then [tex]P(t)=64e^{0.027t}[/tex].
2008 is 18 years after 1990, so [tex]P(18)=64e^{0.027 \cdot 18} \approx 104.1[/tex]
The exponential growth of population in 2008 is 95.4 million
What is exponential growth factor?
The exponential growth or decay formula is given by
x ( t ) = x₀ × ( 1 + r )ⁿ
x ( t ) is the value at time t
x₀ is the initial value at time t = 0.
r is the growth rate when r>0 or decay rate when r<0, in percent
t is the time in discrete intervals and selected time units
Given data ,
Let the population of the country in 1993 be = 64 million
The exponential growth rate r = 2.7 %
So , the population of the country in 2008 is calculated by
The time t in years = 2008 - 1993
= 15 years
So , the equation for exponential growth rate is given by
x ( t ) = x₀ × ( 1 + r )ⁿ
And substituting the values in the equation , we get\
x ( 15 ) = 64 × ( 1 + 0.027 )¹⁵
x ( 15 ) = 64 × ( 1.027 )¹⁵
x ( 15 ) = 64 × 1.49127
x ( 15 ) = 95.4413
So , the value of x ( 15 ) = 95.4 million
Hence , The exponential growth of population in 2008 is 95.4 million

Solve the following proportion.
10/x = 6/15
x =
these are fractions.
Answer: 25
Step-by-step explanation:
10 6
/ = /
x 15
Just cross multiply, so do 10*15 = 6*x
10*15 = 6*x
150 = 6*x
Divide by 6 on both sides to isolate x.
25 = x
Answer:
x = 25
Step-by-step explanation:
first simplify the 6/15 by dividing 6 and 15 both with 3
10/x = 2/5
then multiply with 5x on both sides to get rid of the fraction:
5x * (10/x) = 5x * (2/5)
then shorten and solve:
5 * 10 = x * 2
50 = x * 2
25 = x
Find five consecutive odd integers if the sum of the first three integers is 3 more than the sum of the last two.
Answer:
The 5 consecutive odd integers are 11 , 13 , 15 , 17 , 19
Step-by-step explanation:
The Difference between any odd Integer and its consecutive Integer = 2
So let the 3rd Odd Integer be x
Then the 1st Odd Integer is x - 2
and the 2nd Odd Integer is x - 4
and the 4th Odd Integer is x + 2
and the 5th Odd Integer is x + 4
Since the Sum of the 1st three integers is 3 more than the sum of the last two
Then 1st + 2nd + 3rd = 4th +5th +3
Then (x) + (x - 2) + (x - 4) = (x + 2) + ( x + 4) +3
Then 3x - 6 = 2x + 9
subtract 2x from both sides
3x - 2x -6 = 9
x - 6 = 9
Add 6 for both sides
Then x = 9 + 6 = 15
So the 3rd odd Integer is 15
So the five consecutive odd integers are 11 , 13 , 15 , 17 , 19
