the map below shows certain locations in town. Use the map and the box of equations at the right to answer the questions below.
Step-by-step explanation:
Gas Station (2,7) -> y = [tex]\frac{1}{2}[/tex]x + 6 if you plug in the numbers it becomes 7 = 1 + 6
Grocery Store (6,3) -> x + 6y = 24 plug in the numbers it becomes 6 + 18 = 24
Bowling Ally (1, -3) -> 6x + 3y = -3 plug in numbers 6 -9 = -3
Movies (7, -7) -> y = -7 because the y coordinates for the movies = -7
Park(-2, -4) -> -6x + 2y = 4 plug in the numbers 12 - 8 = 4
Coffee Shop (-6, -8) -> -10x + 5y = 20 plug in the number 60 - 40 = 20
Gym (-8, -3)-> y = - [tex]\frac{1}{2}[/tex]x - 7 plug in the numbers -3 = 4-7
School (-6, 6) -> y = - [tex]\frac{1}{3}[/tex]x +4 plug in the numbers 6 = 2 + 4
6x + 3y = -3 quadrant II is (-x, y)
rearrange the equation:
3y = -6x - 3
y = -2x - 1
if x is -1, y will be 2 -1 = 1. So another solution for this equation is (-1, 1).
Ismail has 44 sweets more than Johan. If the number of sweets Johan has is of the
7/11 of the number of sweets Ismail has, how many sweets do they have altogether?
Answer:
121
Step-by-step explanation:
Find out the amount of units Ismail have more than Johan.
11 - 7 = 4 units
Since Ismail has 44 more sweets than Johan and 4 more units..
4 units = 44
1 units = 44 ÷ 4 = 11
Altogether, there's 11 units.
11 units = 11 x 11 = 121
please help me with geometry question :)
Given:
The graph of a triangle ABC.
A line is parallel to AC and passes through the point D.
To find:
The point at which the intersection of this parallel line be with the line BC.
Solution:
From the given figure it is clear that A(1,7), B(9,7), C(9,1) and D(5,7).
Slope of AC is
[tex]Slope=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]Slope=\dfrac{1-7}{9-1}[/tex]
[tex]Slope=\dfrac{-6}{8}[/tex]
[tex]Slope=\dfrac{-3}{4}[/tex]
Slope of parallel lines are same. So, the slope of parallel line is also [tex]-\dfrac{3}{4}[/tex].
The parallel line passes through D(5,7) with slope [tex]-\dfrac{3}{4}[/tex]. So, the equation of the line is
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-7=-\dfrac{3}{4}(x-5)[/tex]
[tex]y=-\dfrac{3}{4}(x)+\dfrac{15}{4}+7[/tex]
[tex]y=-\dfrac{3}{4}(x)+\dfrac{28+15}{4}[/tex]
[tex]y=-\dfrac{3}{4}(x)+\dfrac{43}{4}[/tex] ...(i)
From the given graph it is clear that the line BC is a vertical line. So, the x-coordinates of all the points lie on BC are the same, i.e., 9.
Putting x=9, we get
[tex]y=-\dfrac{3}{4}(9)+\dfrac{43}{4}[/tex]
[tex]y=\dfrac{-27}{4}+\dfrac{43}{4}[/tex]
[tex]y=\dfrac{16}{4}[/tex]
[tex]y=4[/tex]
Therefore, the point at which the intersection of this parallel line be with the line BC is (9,4).

Find the value of x.
Answer:
64
Step-by-step explanation:
Answer:
The answer is 61˙
Step-by-step explanation:
The total trapezoid is supposed to equal to 360
100 + 130 + 66 + x
230 + 66 + x
299 + x
360 - 299 = 61
Problem 2
An online retailer advertises the following shipping and handling fees for every order:
Order Amount ($)
0 – 49.99
50 – 75.99
76+
Shipping and Handling ($)
3.95
11.95
5.95
The sales tax in Arizona on online orders is 5.6%. Use this information to answer the following questions.
**Assume that the shipping and handling is added after the sales tax is applied to the order.
Part a)
Using the information above, write an equation that represents the total cost as a function of the order amount in a customer’s “cart”. (Remember: Identify your input and output variables, and use proper notation – I recommend you handwrite your function and add a picture in to this document)
Part b)
Genevieve, who lives in Prescott, has a cart total of $74.50. How much will her total cost be? (Remember: Show all your work for full credit)
Part c)
Rafael, who lives in Tucson, paid $89.20 for his items. How much was his cart total? (Remember: Show all work, and make sure you get all of the answers)
Answer:
Let the 'cart' total is x and total payment is y.
The sales tax is 5.6% added to the 'cart' amount and then shipping and handling fee added.
Part AThere are three intervals as below and function added accordingly:
0 < x ≤ 49.99 ⇒ y = x + 5.6% + 3.95 = 1.056x + 3.9550 ≤ x ≤ 75.99 ⇒ y = x + 5.6% + 11.95 = 1.056x + 11.95x ≥ 76 ⇒ y = x + 5.6% + 5.95 = 1.056x + 5.95Part Bx = 74.50, this falls in the second intervaly = 74.50*1.056 + 11.95 = $90.62 (rounded )Part Cy = 89.20, this is close to the number we got in part B and we assume it is same - the middle interval.
89.20 = 1.056x + 11.951.056x = 89.20 - 11.951.056x = 77.25x = 77.25 / 1.056x = 73.15 (rounded )-----------------------------------------
Note. Shipping and Handling charges seems incorrectly ordered. If so the answers above all should change accordingly.6. 5x + 3y = 22

Find the slope of the line passing through the points (-2,3) a
and
(-9,6).
===================================================
Apply the slope formula
m = (y2-y1)/(x2-x1)
m = (6-3)/(-9-(-2))
m = (6-3)/(-9+2)
m = 3/(-7)
m = -3/7
This means each time you go down 3 units, you go to the right 7 units.
Slope = rise/run = -3/7
rise = -3 and run = 7
Please help with this slope problem!!

Lorene plans to make several open-topped boxes in which to carry plants. She makes the boxes from rectangular sheets of cardboard from which she cuts out 10-in squares from each corner. The length of the original piece of cardboard is 20 inches more than the width. If the volume of the box is 1250 in^3, determine the dimensions of the original piece of cardboard.
(figure of the problem is shown in attached picture)
The dimensions of the original piece of cardboard are _ inches by _ inches.
!! PLEASE HELP !! THANKS !!
Answer:
25 in by 45 in.
Step-by-step explanation:
The length of the box will be x + 20 - 10 - 10 = x
The width of the box will be x - 10 - 10 = x - 20
The height of the box will be 10
So the volume = length x width x height
= x(x - 20)10 = 1250
= [tex]10x^{2} - 200x = 1250[/tex]
[tex]10x^{2} -200x - 1250 = 0[/tex]
[tex]10(x^{2} -20x - 125)\\[/tex] = 0
10(x + 5)(x - 25) =0
x = -5 x = 25
- 5 must be discarded since a length cannot be negative.
Therefore x = 25 in = width of piece of cardboard
x + 20 = 25 + 20 = 45 in = length of piece of cardboard

What is the mass of a truck if it
produces a force of 14000 N while
accelerating at a rate of 5 m/s/s?
Answer:
force (f)= 14000N
acceleration (a)=5m/s²
mass (m)=?
we have,
f=ma
14000=m×5
14000/5=m
2800=m
therefore Mass is 2800kg

Answer:
12, 17, 30.
Step-by-step explanation:
Given
(a) to (d)
Required
Which cannot represent a triangle
The rule to use is:
[tex]a + b > c[/tex]
So, we have: 12, 17, 30.
[tex]12 + 17 > 30[/tex] ===> [tex]29 > 30[/tex] --- False
[tex]12 + 30 > 17[/tex] ==> [tex]43 > 17[/tex]
[tex]17 + 30 > 12[/tex]
Because, one of the inequalities is False, then this can not represent the sides of a triangle.
4 x 2/3 is less than 2/3 , since 2/3 is less than 1 is true or false ?
