Answer:
16.6%
Step-by-step explanation:
First, find the difference between the prices:
$3.95 - $3.45 = $0.50
Then, divide the difference by yesterday's price.
$0.50 ÷ $3.95
≈ 0.166
≈ 16.6%
Answer:
12.7%
Step-by-step explanation:
$3.95 - $3.45 = $.50
$.50 / $3.95 = .127 = 12.7%
twice the difference of a number 4 is 5.

1. A piece of power transmission equipment is being designed. The design includesa set of three different meshed gears with a total of 107 teeth between them. If thesecond gear has 13 more teeth than the first gear. The third gear has 15 more teeththan the second gear.How many teeth does the second gear have?
where x is the first, y the second and z the third
the second gear has 13 more teeth than the first gear
[tex]x+13=y[/tex]The third gear has 15 more teeth than the second gear
[tex]y+15=z[/tex]we need solve z form the third equation and solve x from the second equation an replace on the first
[tex]\begin{gathered} z=y+15 \\ x=y-13 \end{gathered}[/tex]replacing
[tex]\begin{gathered} (y-13)+y+(y+15)=107 \\ y-13+y+y+15=107 \\ 3y+2=107 \\ 3y=105 \\ y=35 \end{gathered}[/tex]so, the second gear have 35 teeth
Ainsley had 3 yards of string. She used 1/4 yard for a project. She wants to divide the rest into pieces 5/6 yard long. How many pieces can she make?
She can make 3.3 pieces from the remaining length
How to determine the number of pieces to make?From the question, the given parameters are:
Length of string = 3 yardsAmount used for project = 1/4 yardLength of each piece = 5/6 yardWe start by calculating the length of the remaining pieces as a whole
This is calculated as
Length of remaining piece + length used for project = Length of string
Substitute the known values in the above equation
So, we have
Length of remaining piece + 1/4 yard = 3 yards
Subtract 1/4 from both sides
Length of remaining piece = 2.75 yards
The number of pieces is then calculated as
Pieces = Length of remaining pieces/Length of each piece
This gives
Pieces = 2.75 yards/(5/6 yards)
Evaluate the quotient
Pieces = 3.3
Hence, the number of pieces she can make is 3.3

Describe what the graph of the proportional relationship would look like.
A line passes through the point (0, 0) and continues through the point (3, 12).
A line passes through the point (0, 0) and continues through the point (2, 8).
A line passes through the point (0, 0) and continues through the point (6, 24).
A line passes through the point (0, 0) and continues through the point (12, 3).
A graph of which best describes what the proportional relationship would look like is: D. A line passes through the point (0, 0) and continues through the point (12, 3).
What is a graph?In Mathematics, a graph is used to graphically represent data points on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis respectively.
Additionally, a graph that represents a proportional relationship between two variables would always have a straight line with its data points passing through the origin (0, 0).
Since the graph represents a proportional relationship we have:
Constant of proportionality, k = 12/3 = 8/2 = 24/6 = 4
Ratio = 24:6 = 12:3.
Therefore, (0, 0) and (12, 3) are points on this graph that represents a proportional relationship.

Angle IJL is 54 because congruent angles have equal measure.
What are congruent angles?
Congruent angles are two or more angles that are identical to each other. Thus, the measure of these angles is equal to each other. The type of angles does not make any difference in the congruence of angles, which means they can be acute, obtuse, exterior, or interior angles.
According to question, angle m IKL = 54
And AB// CD and EF// GH
Angle IKL is alternate interior angle to angle HLK
m angle HLK= m angle IKL (congruent angles have equal measure)
m angle HLK= 54
Similarly, m angle IJL = m angle HLK
Hence, angle IJL= 54

The answer is either Option (a) or option(b) or both the options i.e, 120 or √144
What is Integer ?
An integer is a whole number from the set of -ve , non-negative , +ve and 0 numbers.
Let's see how both the option is correct
we know, integers are 0,1, 2, 3, .... or -1, -2 , -3 ......
Means the number which is not in fraction or decimal value or root.
so, by seeing option(a) we can say it's an integer
but in option(b) it's the root so how it is integer
The answer is simple it's perfect square of 12 so √144 = 12 so that means it have the value which is not in fraction. By that we can say that option(b) is also an integer
Now, in option(c) and (d) they are not the perfect square and their root results in decimal values. so we cannot tell them as an integer value.
Hence, the answer is either Option (a) or option(b) or both the options.

If the population grows exponentially, then at what annual rate is the population growing? Round the answer to the nearest tenth of a percent.
The population is growing at an annual rate of 16.2%
Here, we want to calculate the exponential growth rate

S is the midpoint of segment OU. OS= 7x-9 and SU=4x+3. Determine the length of segment OU.
Answer:
The equation for the value of OU is;

Given that S is the midpoint of segment OU.
Then;
[tex]OU=OS+SU[/tex]Given in the question;
[tex]\begin{gathered} OS=7x-9 \\ SU=4x+3 \end{gathered}[/tex]Substituting the values of OS and SU to get OU;
[tex]\begin{gathered} OU=OS+SU \\ OU=7x-9+4x+3 \\ OU=7x+4x-9+3 \\ OU=11x-6 \end{gathered}[/tex]Therefore, the equation for the value of OU is;
[tex]OU=11x-6[/tex]if the sum of the first three terms of a GP is half it's sum to infinity. find it's positive common ratio.
Answer:
See below
Step-by-step explanation:
Sum of n = inf = a / ( 1-r) one half of this = 1/2 ( a/(1-r) )
Sum of first 3 terms = a ( 1- r^n) / ( 1-r) = a (1-r^3) / (1-r)
The underlined value are equal ( given in the Q)
1/2 a / (1-r) = a ( 1-r^3) / (1-r) Multiply both side by ( (1-r) )
1/2 a = a ( 1-r^3) divide both sides by a
1/2 = 1- r^3 subtract 1 from both sides
-1/2 = - r^3
1/2 = r ^3
r = cuberoot ( 1/2) = 1/2 ^(1/3) = .793700526

2 5 4 Q Find the area of the shaded region above.
As you can see in the given figure, there are two different shapes.
One is a rectangle and the other is a triangle.
Recall that the area of a rectangle is given by
[tex]A_R=L\cdot W[/tex]Where L is the length and W is the width.
As you can see from the figure,
W = 4
L = 5
So the area of the rectangle is
[tex]A_R=L\cdot W=5\cdot4=20[/tex]Recall that the area of a triangle is given by
[tex]A_T=\frac{1}{2}\cdot b\cdot h[/tex]Where b is the base of the triangle and h is the height of the triangle.
As you can see from the figure,
b = 4
h = 2
So the area of the triangle is
[tex]A_T=\frac{1}{2}\cdot b\cdot h=\frac{1}{2}\cdot4\cdot2=\frac{1}{2}\cdot8=\frac{8}{2}=4[/tex]Now the total area of the shaded region is the sum of the area of the rectangle and the area of the triangle.
[tex]A=A_R+A_T=20+4=24[/tex]Therefore, the area of the shaded region is 24

The half life of iron-59 is 44.5 days. How much of
a 50g sample would remain after 178 days?
Answer:
If the half-life of a nuclide is 44.5 days, then 178 days is four half-lives.
explanation:
After four half-lives, 0.0625 (0.54) of the original nuclides remains. If 50g is the original mass, then the mass after 4 half-lives is 3.125g.
AT = A0 2(-T/H)
A178 = (50) 2(-44.5/178)
A178 = 3.125
