The slope of the line is 60 and speed of the bus is 60 miles per hour
The slope of the line is the measure of the steepness. In other words the slope of the line is the change in y coordinate with respect to the change in x coordinate.
Here the points are
(1,60) and (2,120)
The slope of the line m =[tex]\frac{y_{2}-y_{1} }{x_2-x_1}[/tex]
Where m is the slope of the line
[tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are the coordinates of the points
Substitute the values in the equation
The slope of the line m = [tex]\frac{120-60}{2-1}[/tex]
= 60
The speed = Distance / Time
Take one point (2,120)
The distance = 120 miles
Time = 2 hours
The speed = 120/2
= 60 miles per hour
Hence, the slope of the line is 60 and speed of the bus is 60 miles per hour.

Mrs. Byers rents a water trampoline for her son's birthday party. The delivery fee for the trampoline is $75, plus a rental fee of $8 per hour. She wants to spend less than $125 on the trampoline. Find h, the number of hours Mrs. Byers could rent the trampoline?
Answer:
h= 6
Step-by-step explanation:
To find out the value of h, start by forming an equation for the cost of renting a trampoline:
Cost of renting= $(75 +8t), where t is the rental duration.
When the cost is $125,
75 +8t= 125
Subtract 75 from both sides:
8t= 125 -75
8t= 50
Divide both sides by 8:
t= 50 ÷8
t= 6.25
Since she wants to spend less than $125, let's round the value down to the nearest hour.
∴ h= 6
Thus, she could rent it for 6 hours.
Let's check!
Total cost of renting for 6 hours
= 6(8) +75
= $123
Total cost of renting for 7 hours
= 7(8) +75
= $131
Hence, 6 hours is indeed the maximum number of hours she can rent the trampoline for, such that the total cost is less than $125.

A factory produce 11,650 gallon of lemonade 4,950,fewer gallons of ice tea than lemonade
Factories produce a total of 21550 gallons in a calendar year.
The gallon is used as a unit of volume in both imperial and US customary measurements.
Eight pints make up a gallon, which is a unit of measurement for liquids. It is equivalent to roughly 4.546 litres in Britain. It is roughly equivalent to 3.785 litres in America.
Lemonade, it has been stated, equals 11,650 gallons.
Lemonade = 4,950 fewer than ice tea.
Ice tea: 3,500 fewer than Root beer.
Using the formula Ice tea = 11,650 - 4,950
6700 gallons of iced tea
Root beer = 6700 - 3,500
3200 gallons equals root beer.
Total manufacturing output for a year is equal to 11,650 + 6700 + 3200
Thus, 21550 gallons are produced in total by factories each year.

Step-by-step explanation:
it is just a matter of definition that can be easily looked up.
the domain is the interval or set of all valid x values.
while the range is the interval or set of all valid y (function result) values.
so, the domain here is every value of x used in this function.
e.g. does x = -6 have a functional (y) value in the curve ?
no, it does not.
x = - 4 ? no.
x = -2 ? no.
x = -1 ? ah, yes, this is just the left-most point of the curve.
and then all x values further to the right of -1 are covered. as the arrows indicate : into all eternity ("to infinity and beyond !")
so, the domain is [-1, +infinity).
and you need to use B.
please note, the round bracket indicates that that ends of the interval is not included or undefined (after all, infinity is not a number we can work with, it is basically undefined and only represents a principle).
for the range this is tricky, as the graph does not really show us the limit. it could be y = -1 or 0 down to y = -9 or -10.

The tables show relationships between two quantities. Which table shows a proportional relationship? A INSERT_TEXT B INSERT_TEXT C INSERT_TEXT D INSERT_TEXT
The table that shows a proportional relationship between the variables a and b is Table B, which is the second table graphed.
What is a direct proportional relationship?In a direct proportional relationship, the output variable is found by the multiplication of the input variable and the constant of proportionality k, as follows:
y = kx.
Hence, a data-set such as a table will represent a proportional relationship if the ratio between the output and the input is the same for all the terms of the relationship.
In this problem, we have that:
Table 1 does not show a proportional relationship between a and b, as the ratios are of 3, 3 and 4, respectively.Table 2 shows a proportional relationship between a and b, as the ratios are of 5/4, 5/4 and 5/4, respectively, that is, all the ratios are the same.Table 3 does not show a proportional relationship between a and b, as the ratios are of 3, 3 and 4, respectively.Table 4 does not show a proportional relationship between a and b, as the ratios are of 4/3, 3/2 and 4/3, respectively.What is the missing information?In the context of this problem, the tables are missing, and are given by the image at the end of the answer.

What is half-life?The amount of time needed for a quantity to decrease to half of its original value is referred to as its half-life.
In nuclear physics, this word is often used to define the rate at which unstable atoms undergo radioactive decay or the amount of time stable atoms are able to persist.
Additionally, the phrase may be used in a broader sense to define any form of exponential decline.
Generally,
A = A0e^{-kt}
Therefore
A(t) = A0e^{[ln(0.5) / 7310 t}, t in years

Here are three different recipes for Orangey-Pineapple Juice. Two of these mixtures taste the same and one tastes different.
Recipe 1: Mix 4 cups of orange juice with 6 cups of pineapple juice.
Recipe 2: Mix 6 cups of orange juice with 9 cups of pineapple juice.
Recipe 3: Mix 9 cups of orange juice with 12 cups of pineapple juice.
Which two recipes will taste the same, and which one will taste different? Explain or show your reasoning.
Using ratio we can conclude that Recipe 1 and recipe 2 tastes the same.
The multiplicity of two integers is shown by a ratio. For instance, the ratio of oranges to lemons in a fruit plate would be eight to six if there were eight oranges and six lemons.
An ordered pair of integers, a fraction with the first number in the numerator and the second in the denominator, or the value represented by this fraction are all ways to conceptualize ratios. Rational numbers, and occasionally natural numbers as well, are ratios of counts stated in terms of (non-zero) natural numbers. When two numbers are compared using the same unit of measurement, which frequently occurs, their ratio is a dimensionless number. A rate is created by multiplying two amounts with different unit measurements.Let us consider the ratio of the orange juice top the pineapple juice for the 3 recipes.
Recipe 1 = 4 : 6 = 2 : 3
Recipe 2 = 6 : 9 = 2 : 3
Recipe 3 = 9 : 12 = 3 : 4

PLEASE HELP MEEEEEEEE!!!
I really need to understand how to work out this problem and solve it!
Thank You!
The final price of the television is $299.53.
Discount is somewhat a reduction in the actual or usual price of the object or service. Whereas, tax is the money that we have to pay to the government.
Price of television before discount = $375.00 (given)
Discount given = 25% (given)
25% of $375 is,
$375* (25/100)= $93.75.
The cost of the television after sale off and before the sales tax is:
$375- $93.75= $281.25
The sales tax = 6% (given)
$281.25* (6.5/100)= $18.28
The price of the television including everything is,
$281.25+ $18.28= $299.53
Therefore, we can conclude the the final price of television is $299.53.

Suppose that country A and country B initially have the same per capita GDP. After that, country A grows at 3.5 percent per year and country B grows at 7 percent per year. According to the rule of 70, after 40 years what is the ratio of country B's GDP to country A's?
Using the Rule of 70, it is found that after 40 years, the ratio of country B's GDP to country A's is of 2.
What is the Rule of 70?The rule of 70 is a rule that is used to determine how long it takes for an amount to double, dividing 70 by the variable's growth rate, as a percentage.
Country A grows at 3.5 percent per year, hence the time it takes to double is:
70/3.5 = 20 years.
Hence in 40 years, it's GDP will be of:
4n, in which n is the current GDP, and 4 because it will have doubled twice.
Country B grows at 7 percent per year, hence the time it takes to double is:
70/7 = 10 years.
Hence in 40 years, it's GDP will be of:
8n, in which n is the current GDP, and 8 because it will have doubled three times.
Then the ratio of country B's GDP to country A's will be of:
8n/4n = 2.
