A map’s scale is 1 inch: 3.5 miles. If the actual distance between two places is 77 miles, then they will be ____ inches away from each other on the map.
==================================
Work Shown:
(1 inch)/(3.5 miles) = (x inches)/(77 miles)
1/3.5 = x/77
1*77 = 3.5*x ..... cross multiply
77 = 3.5x
3.5x = 77
x = 77/3.5
x = 22
22 inches on paper correspond to 77 miles in real life.
Hans is using frequent flier miles to fly to a location 450 miles away, but the airline he is using still charges $15.89 for fees and taxes and $0.17 to redeem each mile. In the equation below, x represents the distance Hans is flying, and y represents the cost of the trip. y = $0.17x + $15.89 How much did Hans pay for his trip?
Given :
Hans is using frequent flier miles to fly to a location 450 miles away, but the airline he is using still charges $15.89 for fees and taxes and $0.17 to redeem each mile.
In the equation below, x represents the distance Hans is flying, and y represents the cost of the trip. y = $0.17x + $15.89 .....1)
To Find :
How much did Hans pay for his trip.
Solution :
x = 450 miles.
Putting value of x in equation 1 we get :
y = $(0.17×450 + 15.89)
y = $(76.5+15.89)
y = $92.39
Therefore, Hans will pay $92.39 for his trip.
Hence, this is the required solution.

Use cross products to demonstrate whether or not the two ratios are equivalent: 4/6 and 14/21
Answer:
The answer is true.
Step-by-step explanation:
[tex] \frac{4}{6} = \frac{14}{21} \\ 84 = 84[/tex]
Because the last equation, 84=84, is true, then the ratios are true.

Which function is a horizontal translation of the parent quadratic function, f(x) = x2
O A. ;(z) = x2 - 4
B. g(x) = (x - 4)
C. k(x) = -42
D. h(x) = 4,2
The function that represents the horizontal translation of the parent function is (b)g(x) = (x - 4)^2
How to determine the horizontal translation?The function is given as:
f(x) = x^2
An horizontal translation is represented using:
f'(x) = (x ± h)^2
Where h does not equal to 0
From the list of options. we have:
g(x) = (x - 4)^2
Hence, a function that represents the horizontal translation of the parent function is (b)g(x) = (x - 4)^2

How many 9-inch ribbons can be cut from 112yards of ribbon? show work
Answer:
448 ribbons
Step-by-step explanation:
in order to find this, you need to convert the yards into inches. there are 36 inches is a yard (a yard is 3 feet and one foot is 12 inches ) so you would multiply 112 and 36 to find the total number of inches it woulde be. 112x36=4,032. Now that you know the total number of inches, divide it by 9 to find the total number of ribbions you can make.
4,032/9= 448
so you could make a total of 448 ribbons
Answer:
12.4
Step-by-step explanation:
Do 112 divided by 9
Find the x and y intercepts of the graph of the linear equation -x + 8y = 4
Answer: x-int: (-4, 0), y-int: (0, 1/2)
Step-by-step explanation:
x-int: when y = 0
-x + 8*0 = 4
-x = 4
x = -4
(-4, 0)
y-int: when x = 0
0 + 8y = 4
8y = 4
y = 1/2
(0, 1/2)

Which answer choice is a solution to the inequality 1.5x+3.75≥5.5? –1 1 1.5 0
Answer:
x ≥ 1.17Step-by-step explanation:
[tex]1.5x+3.75≥5.5[/tex]
First of all subtract 3.75 from both sides of the equation
That's
[tex]1.5x + 3.75 - 3.75 \geq5.5 - 3.75 \\ 1.5x \geq1.75[/tex]
Divide both sides by 1.5
[tex] \frac{1.5x}{1.5} \geq \frac{1.75}{1.5} \\ [/tex]
We have the final answer as
