You go on a hayride to take photographs of landmarks. The map shows your path and two landmarks. Each unit in the coordinate plane corresponds to 10 yards. Approximate your minimum distance from the giant pumpkin. If necessary, round your answer to the nearest tenth.
Answers
Using the distance between a point and a line and the conversion of the units to yards, it is found that the minimum distance from the giant pumpkin is of 8.9 yards.
What is the distance between a points and a line?Suppose that we have a linear function defined according to the following rule, in standard notation:
Ax + By + C = 0.
And a point with coordinates given by:
P(x*,y*)
The shortest distance between the line and the point is given by:
[tex]d = \frac{|Ax^\ast + By^\ast + C|}{\sqrt{A^2 + B^2}}[/tex]
The line of the path in this problem has:
Intercept of 0, as when x = 0, y = 0.Slope of 0.5, as when x increases by 4, y increases by 2.Hence:
y = 0.5x.
-0.5x + y = 0
-x + 2y = 0.
The coefficients are:
A = -1, B = 2.
The giant pumpkin has coordinates given by:
(x*, y*) = (-4, -3).
Hence the distance in units is given by:
d = |(-1)(-4) + 2(-3)|/sqrt(5)
d = 2/sqrt(5)
d = 0.89 units.
Each unit is equivalent to 10 yards, hence the shortest distance in yards is given by:
0.89 x 10 = 8.9 yards.

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 ratio of two cars, the Thunderbolt and the Flash, in terms of their miles per gallon was 6:5. The new version of the Flash added 14 miles per gallon and now the ratio is 24:27 .
What is the miles per gallon of the Thunderbolt?
The Thunderbolt gets
miles per gallon.
Answers
If the ratio the Thunderbolt and the Flash, in terms of their miles per gallon was 6:5 and the new version of the Flash added 14 miles per gallon and now the ratio is 24:27, then the miles per gallon of the Thunderbolt is 15.27 miles per gallon
The ratio the Thunderbolt and the Flash, in terms of their miles per gallon = 6:5
Then the miles per gallon of the Thunderbolt and the Flash is 6x and 5x respectively
The new version of the Flash added 14 miles per gallon
New ratio of the cars = 24:27
Therefore the equation is
5x+14 = 27x
27x-5x = 14
22x = 14
x = 7/11
The miles per gallon of the Thunderbolt = 24x
= 24×7/11
= 15.27 miles per gallon
Hence, If the ratio the Thunderbolt and the Flash, in terms of their miles per gallon was 6:5 and the new version of the Flash added 14 miles per gallon and now the ratio is 24:27, then the miles per gallon of the Thunderbolt is 15.27 miles per gallon

1/2 a / (1-r) = a ( 1-r^3) / (1-r) Multiply both side by ( (1-r) )

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

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 ✓
