A bag of cookies weighs 19.1 ounces. The bag contains 50 cookies. How much does each cookie weigh?
O2.6 ounces
O 0.3 ounces
O 0.382 ounces
O 3.82 ounces
Answers
Answer: 0.382 ounces
Step-by-step explanation:
To find the unit rate of the weight of a single cookie, we will use division.
19.1 ounces per bag / 50 cookies in the bag = 0.382 ounces per cookie
To check our work, we will multiply 0.382 ounces per cookie by 50. Since the bag, with 50 cookies, weighs 19.1 ounces, 0.382 times 50 should equal about 19.1 ounces.
0.382 ounces * 50 cookies = 19.1 ounces ✓

if the sum of the first three terms of a GP is half it's sum to infinity. find it's positive common ratio.
Answers
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
Emery borrowed money from her brother to buy a new phone and is paying off a fixed amount each week. After 2 weeks, she will owe $456, and after 5 weeks, she will owe $228.
a. What was the original amount Emery borrowed?
b. How much does she pay each week?
c. How useful are equations in point-slope and slope-intercept forms for answering each question?
Answers
The $456 and $228 Emery owed from the amount she borrowed to buy a new phone after 2 weeks and 5 weeks gives;
a. The original amount owed is $608
b. Emery pays $76 each week
c. The point and slope and slope and intercept both gives the amount Emery pays each week as the slope, while the slope and intercept form further gives the original amount borrowed as the y–intercept, c
What is a straight line equation?A straight line equation is one which expresses a linear relationship between variables
Let y represent the original amount of money Emery borrowed from her brother, and let m represent the amount she pays each week to settle the loan, we have;
The given parameters are;
The amount Emery owes after 2 weeks = $456
The amount Emery will owe after 5 weeks = $228
a. The above information can be expressed by writing the following equations;
456 = y - 2•m...(1)
228 = y - 5•m...(2)
Subtracting equation (2) from equation (1) gives;
y - 2•m - (y - 5•m) = 456 - 228 = 228
3•m = 228
Therefore;
m = 228 ÷ 3 = 76
m = 76
The original amount Emery borrowed, y, from equation (1) is therefore;
y = 456 + 2•m
y = 456 + 2 × 76 = 608
The original amount Emery borrowed, y, is $608
b. The amount Emery pays each week, m = $76
c. The straight line equation in point and slope form is presented as follows;
[tex] y_2 - y_1 = m•(x_2 - x_1) [/tex]
From the above equation, the two points (456, 2) and (228, 5) given in the question can be used to find the slope, m, which is the amount paid each month
The slope and intercept form of a straight line equation is y = m•x + c
From the slope and intercept form, we have;
The slope, m = The amount Emery pays per month
The intercept, c = The original amount Emery borrowed
Therefore, both forms of the straight line equation gives the amount Emery pays each week, while the slope and intercept form also gives the original amount Emery borrowed

2 5 4 Q Find the area of the shaded region above.
Answers
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

A native wolf species has been reintroduced into a national forest. Originally 200 wolves were transplanted. After 3 years, the population had grown to 270 wolves. 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
Mathematically, we can write the exponential equation of growth as follows;

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?
Answers
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

The standard deviation is a statistic that measures the spread of a dataset relative to its mean.
From the given options, find the range in each of them:
[tex]Range=Highest\;Value-Lowest\;Value[/tex]• Option 1: Range = 26-22=4
,• Option 2: Range=14-10=4
,• Option 3: Range=18-14=4

,• Option 5: Range = 19-4=15
We see that the dataset in Option 5 has a far greater range and thus the dataset will have the biggest spread relative to its mean.
Option 5 has the largest standard deviation.

Put (1) in (2),
5B(B) – 3(5B + B)= 176
5B² – 3(6B)= 176
5B² – 18B – 176= 0
(B – 8)(B + 22/5)= 0
B= 8 and B= –22/5

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.
