Answer:
7hours maxStep-by-step explanation:
let the total charges be y
and the number of hours be t
the total cost can be modelled linearly as
y=mt+c
given that
c=$41
m=$8.30
Therefore for y=99.10, we want to solve for t
99.1=8.3t+41
solve for t
99.1-41=8.3t
58.1=8.3t
t=58.1/8.3
t=7
therefore the time is 7hours max
Use the slope formula to find the slope between the given two points?
(2, 1) and (8,9)
Answer:
4/3
Step-by-step explanation:
Slope = (y2-y1)/(x2-x1)
(9-1)/(8-2)
4/3
Answer:
[tex]\frac{4}{3}[/tex]
Step-by-step explanation:
(2,1) (8,9)
The formula that you would use is:
[tex]\frac{y_{2}-{y_1} }{x_2-x_1}[/tex]
So, 2 could be [tex]x_1[/tex] and 1 could be [tex]y_2[/tex]
and 8 could be [tex]x_2[/tex] and 9 could be [tex]y_2[/tex]
When we insert these numbers into the equation, we get:
[tex]\frac{9-1}{8-2}[/tex]
When we solve that we get:
[tex]\frac{8}{6}[/tex]
Now we simplify it by dividing both the numerator and denominator by 2, which would give us:
[tex]\frac{4}{3}[/tex]

Which is the best estimate of the number of cups of oatmeal that Liam had left in the container at the end of the five-day week?
2 and one-half

3 and one-half

9514 1404 393
Answer:
3 1/2
Step-by-step explanation:
The amount is reduced by 4/9 cup each day for 5 days, so the amount remaining is ...
(5 1/2) - 5(4/9) = 11/2 -20/9 = (99 -40)/18 = 59/18 = 3 5/18 ≈ 3.28 . . . cups
This value is (slightly) closer to 3.5 than to 3.0.
The best estimate of the remaining amount is 3 1/2 cups.

The upper-left coordinates on a rectangle are (-1,4) and the upper-right coordinates are (3,4).The rectangle has a perimeter of 24 units Draw the answer on the coordinate planes
Answer:
The answer is below
Step-by-step explanation:
Perimeter of a rectangle = 2(length + breadth)
24 = 2(length + breadth)
length + breadth = 12
The distance between the points of the rectangle (-1, 4) and (3,4) is given as:
[tex]Distance=\sqrt{(x_2-x_1)^2+(y_2+y_1)^2}\\ \\Distance=\sqrt{(3-(-1))^2+(4-4)^2}=4\ units[/tex]
The breadth = 4 units
Length + 4 = 12
Length = 8 units
The lower left x coordinate would be the same as the upper left x coordinate, let us assume that the lower left y coordinate = a
Hence lower left coordinate = (-1, -a). The distance between (-1,4) and (-1, -a) is the length = 6 units
[tex]6=\sqrt{(-1-(-1))^2+(-a-4)^2}\\ \\a=-10[/tex]
lower left coordinate = (-1, 10)
The lower right x coordinate would be the same as the upper right x coordinate, let us assume that the lower right y coordinate = -b
Hence lower right coordinate = (3, -b). The distance between (3, 4) and (3, -b) is the length = 6 units
[tex]6=\sqrt{(3-3)^2+(-b-4)^2}\\ \\b=-10[/tex]
lower right coordinate = (3, -10)

===========================================================
Explanation:
The length of segment MN is the same as the distance from M to N
Count out the spaces from M to N to see that there are 5 spaces, so that's why choice A is the answer.
-------------
Or you can break it down like this:
There are 3 spaces from -3 to 0There are 2 spaces from 0 to 2So we have 3+2 = 5 spaces total between M and N.
-------------
A more formal approach:
Let M = -3 and N = 2
Now subtract and apply absolute value.
|M - N| = |-3-2| = |-5| = 5
or
|N - M| = |2-(-3)| = |2+3| = |5| = 5
Either way, we get a distance of 5 units.
Absolute value is used to ensure that the result is never negative.

Identify the independent and dependent variables. Then write a rule in function notation for the situation, letting x represent the independent variable.
A concert ticket costs $60.
Answer:
independent: number of tickets purchased;
dependent: total cost;
rule: f(x) = 60x
Step-by-step explanation:
The independent variable is the input of a function (the variable whose value determines the value of the output, or dependent variable). In this case, the independent variable is the number of tickets purchased.
The dependent variable is the output of a function (the variable whose value depends on the value of the input, or independent variable). In this case, the dependent variable is the total cost of all tickets purchased.
The total cost of all tickets purchased is equal to $60 times the number of tickets x. Therefore, a function rule for the total cost of all tickets purchased is f(x) = 60x.

Kayla was driving from Philadelphia to Florida, trying to remain at a constant speed as much as possible after she reached the highway. She travelled 139.5 miles after an hour and a half and then 395 miles after 5 hours. Which represents Kayla's speed (rate of change)?
Answer:
Step-by-step explanation:
Speed = change in distance/change in time
S= Δd/Δt
let d1 = 139.5miles
d2 = 395miles
t1 = 1.5 hrs
t2 = 5hrs
Δd = d2-d1
Δd = 395-139.5
Δd = 255.5miles
Δt = 5-1.5
Δt = 3.5hrs
Speed = 255.5/3.5
Speed = 73miles/hr
Hence Kayla's speed is 73miles/hour

Transformation is the movement of a point from its initial location to a new location. If an object is transformed then all its points are also transformed. Types of transformation are reflection, dilation, rotation and translation.
Rotation is a type of transformation that turns an object about a fixed point. Rotation preserves the shape and size of the image. The rotation of point X(x, y) 180° about the origin gives a new point X'(-x, -y) i.e. both the x and y coordinate is negated.

Parallel lines don't intersect
Answer:
Neither parallel or perpendicular.
Step-by-step explanation:
For AB A(-1,-4) and B(2, 11)
x1,y1 x2,y2
Gradient = (y2 - y1)/(x2 - x1)
= (11 - (-4))/(2 - (-1))
= 15/3 = 5.
For CD C(1 , 1) and D(4 , 10)
x1, y1 x2, y2
Gradient = (y2 - y1)/(x2 - x1)
= (10 - 1)/(4 - 1)
= 9/3 = 3
from the above they are neither parallel or perpendicular.

13x-12x+45•12=14-12x-10•5
Answer:
[tex]x=\frac{576}{11}[/tex]
Step-by-step explanation:
13x - 12x + 45 * 12 = 14 - 12x - 10.5
Multiply first
13x - 12x + 540 = 14 - 12x - 50
Combine like terms
x + 540 = 12x - 36
Subtract x from both sides
540 = 11x - 36
Add -36 to both sides
576 = 11x
Divide both sides by 11
[tex]x=\frac{576}{11}[/tex]

please helpppp!
The value of the mass when I is 73 will be m = 14.4.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that when an object of mass m kilogram is attached to the other end of the spring, the spring stretches to a length of / centimeters as shown in the equation l = 24 +3.4m.
The mass will be calculated as below,
73 = 24 + 3.4m
49 = 3.4m
Divide by 3.4 into both sides
14.4 = m
