Answer:
It would be 12 hours for the plane to go from a city to another/the other city
Step-by-step explanation:
(Distance=speed x time, Speed =distance ÷ time and Time =distance ÷ speed)
If you would apply the formula for time then
7,200m ÷ 600m/h = 12 hours
The plane flying at 600 miles per hour can cover a distance of 7200 miles in 12 hours.
What is a unitary method?A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.
Given, The distance between 2 cities is 7,200 miles and a plane can fly 600 miles per hour.
∴ The time required to cover the distance of 7200 miles is,
= (7200/600) h.
= 72/6 h.
= 12 h.

In a survey of 2,000 people who owned a certain type of car, 1,320 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
____% of the people surveyed were satisfied with the car.
(Type a whole number.)
Answer: Total number of those who took part in the survey (T)=2000
Those who were satisfied (t)=1320
Percentage of those who were satisfied (S)=(t/T)*100
S=(1320/2000)*100
S=66%
Therefore only 66% were satisfied

Find the sum of 2√5 and 3√16 in simplest form. Also, determine whether the result is rational or irrational and explain your answer
Answer:
2√5 +12 or 16.47213595....
Step-by-step explanation:
Part A - The sum of 2√5 and 3√16 in its simplest form is 2(√5 + 6).
The given numbers are surds.
To find the sum of 2√5 and 3√16, we perform the arithmetic operation of addition on the surds.
So, 2√5 + 3√16 = 2√5 + 3 × 4 (√16 = 4)
2√5 + 3√16 = 2√5 + 12
Factorizing out the factor 2 from both expressions, we have
2√5 + 3√16 = 2√5 + 6 × 2
2√5 + 3√16 = 2(√5 + 6)
So, the sum of 2√5 and 3√16 in its simplest form is 2(√5 + 6).
Part B - The result is irrational.
The result is irrational because 2(√5 + 6) cannot be expressed as a ratio of two integers since √5 is irrational and √5 + 6 is irrational and thus 2(√5 + 6) is also irrational since it cannot be expressed as a ratio of two integers. Also, its decimal representation is non-terminating or repeating.
Thus, the result is irrational.

A car rental agency charges 150 per week +0.45 per mile to rent car express the weekly cost to rent a car if as a function of the number of miles driven during week X
Answer:
The required function is:
[tex]C(x) = 150+0.45x[/tex]
Step-by-step explanation:
We have to represent the given scenario as an equation or function
Let x be the number of miles driven in a week
Let C(x) be the function of the number of miles driven
As it is given that charges are 150 per week, these charges are constant so they will be used as it is.
It is also given that the cost of car is 0.45 per mile so for x miles the cost will be:
0.45x
Combining both terms, we get
[tex]C(x) = 150+0.45x[/tex]
Hence,
The required function is:
[tex]C(x) = 150+0.45x[/tex]

The cost of a car battery costs $35 wholesale for the automotive store to buy, but they need to markup the cost 40% for the retail price. How much is the markup amount? And how much is the retail price?
Answer:
The markup amount is $14 and the retail price is $49.
Step-by-step explanation:
You can use the following formula to find the retail price with the information provided:
Retail price=Cost*(100%+markup %)
Cost=35
Markup %= 40%
Now, you can replace the values in the formula:
Retail price=35*(140%)
Retail price=49
Now, you can subtract the cost from the retail price to find the markup amount:
49-35=14
According to this, the answer is that the markup amount is $14 and the retail price is $49.

Paul paid $10 for a ticket to the fair and then another $2 per ride. Write an equation to show how many rides x, Paul can take if he has $40.
2x = 40
2x - 10 = 40
10x + 2 = 40
2x + 10 = 40
Answer:
D) 2x+10=40, x= 15 rides
Step-by-step explanation:
Since Paul only bought one ticket, then $10 is the constant of the equation. Since Paul pays $2 per ride, $2 will be the rate/coefficient of the equation.
Since we are solving for x, $40 will be on the right side of the equation
Putting these three facts together, we can make the equation 2x+10=40 which means D is correct

So for dilation when it says to dilate 1/3 how do I solve that (ex. 18, 9)
Answer:
The image of A(18, 9) after dilation by a scale factor of 1/3 will be: A'(6, 3).
Step-by-step explanation:
Let suppose the given point is A(18, 9)
We know that when an object is dilated by a scale factor, it gets reduced, stretched, or remains the same, depending upon the value of the scale factor.
If the scale factor > 1, the image is enlarged If the scale factor is between 0 and 1, it gets shrunk If the scale factor = 1, the object and the image are congruentRule to calculate the dilation by a scale factor 1/3 centered at the origin
P(x, y) → P'(1/3x, 1/3y)
Here, P'(1/3, 1/3y) is the image of P(x, y).
It means the coordinates of the image can be determined by multiplying the coordinates of the original point by 1/3.Thus,
A(18, 9) → A'(1/3(18), 1/3(9)) = A'(6, 3)
Therefore, the image of A(18, 9) after dilation by a scale factor of 1/3 will be: A'(6, 3).
A rectangular box has its length and width doubled and its height tripled. The volume of the new box will be
Answer:
volume of the new box = 12 x volume of the initial rectangular box
Step-by-step explanation:
Let the length, width and height of the rectangle be represented by l, w and h respectively.
The volume of a rectangle is given as;
volume = l x w x h
= lwh
From the given question, the dimension of the rectangle are:
new length = l + l = 2l
new width = w + w = 2w
new height = h + h + h = 3h
So that, the volume of the new box is given as;
volume of the new box = 2l x 2w x 3h
= 12 (lwh)
Therefore,
volume of the new box = 12 x volume of the initial rectangular box

Slope = 2
Y intercept = -3
====================================================
Explanation:
We'll use the template y = mx+b
m = slope
b = y intercept
The y intercept always occurs when x = 0. In this case, b = -3 due to the first row of the table.
The slope is m = 2 because each time we increase x by 1, the y value goes up by 2.
So we can say
m = slope = (rise)/(run) = (change in y)/(change in x) = (2)/(1) = 2
Or we can apply the slope formula
m = (y2-y1)/(x2-x1)
using any two points of the table.
--------------------
Since we know m = 2 and b = -3, this means we get
y = mx+b
y = 2x+(-3)
y = 2x-3
