A taxi charges $3, plus $1.50 for each mile traveled. Mr.Lewis rode in the taxi from his home to the airport and was charged $30. How many miles does Mr.Lewis live from the airport
Answer: 18 milles
Step-by-step explanation: ince we have to figure out how many miles away Mr. Hill lives, first we will subtract:
30 - 3 = 27
Then, divide
27 ÷ 1.50 = 18
So, Mr. Hill lives 18 miles away
Answer:
18miles
Step-by-step explanation:
Full cost minus the original cost.
30-3=27
Now you have to divide the cost by 1.5 because you have to find the distance and that is the cost per mile.
$27/1.5=18mi
Can 0.898989.... be written as a fraction
Answer:
898989/1000000
Step-by-step explanation:
Yes it can be written as a simplified fraction. Since there are 6 numbers to the right of the decimal point, you would move the decimal point to the left of the number.
0.898989
start by moving the decimal point to the left 898989
since you moved your decimal point 6 times to the left it would be 10^6
hence, 898989/1000000
The repeating decimal 0.898989... Or [tex]0.\overline{89}[/tex] can be written as 89/99.
What is a fraction?A fraction is written in the form of p/q, where q ≠ 0.
Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.
We know a repeating decimal can be written as a fraction.
We'll put as many 9s in the denominator as there are repeating digits after the decimal and in the numerator, we'll simply write the repeating digits after the decimal.
So, 0.89898989 is 0.89 repeating.
∴ [tex]0.\overline{89}[/tex] = 89/99.

Maria Gomez is a dental assistant. She earns $12.12 per hour and time and a half for overtime. What is her total pay for a week in which she works 45 hours?ks 45 hours?
Maria Gomez's total pay for the week when she works 45 hours will be $575.70.
How to calculate Total Pay?To calculate Maria Gomez's total pay for a week in which she works 45 hours, we need to consider both regular hours and overtime.
Given:
Regular hourly wage = $12.12 per hour
Overtime rate (time and a half) = 1.5 * Regular hourly wage = 1.5 * $12.12 = $18.18 per hour
Total hours worked in the week = 45 hours
Now, we'll calculate the total pay:
Step 1: Calculate the regular pay for 40 hours (normal working hours):
Regular pay = Regular hourly wage * Regular hours worked
Regular pay = $12.12 * 40 = $484.80
Step 2: Calculate the overtime pay for the additional 5 hours:
Overtime pay = Overtime rate * Overtime hours worked
Overtime pay = $18.18 * 5 = $90.90
Step 3: Add regular pay and overtime pay to get the total pay:
Total pay = Regular pay + Overtime pay = $484.80 + $90.90 = $575.70

Marci has a scale drawing of her new bedroom. On the drawing the length of the bedroom is 2cm. In real life her bedroom is going to be 7 meters in length. What is the scale of the drawing
Answer:
Scale for drawing is 1:350
Step-by-step explanation:
scale is ratio of size of drawing and size of actual object for which the drawing is made
it is represented as
scale = size of drawing : size of actual object
given
length of model in drawing = 2cm
length of bedroom in reality = 7 meter
since there are two units we meter and cm
we convert both in same unit that is cm for simpler calculation
1 meter = 100 cm
7 meter = 7*100 cm = 700cm
length of bedroom in reality = 7 meter = 700 cm
Thus,
scale for drawing = length of drawing/ actual length of bedroom
scale for drawing = 2 cm : 700cm = 1:350
Scale for drawing is 1:350

Find the mean absolute deviation of the set of data. 2, 3, 5, 7, 9
Answer:
2.4
Step-by-step explanation:
To find the mean absolute deviation, find how much each value is away from the mean, and divide it by the number of numbers you have. In this case, the mean is 5, and the deviation of each number is 4, 2, 0, 2, and 4. Add these up and you get 12. Divide 12 by the number of numbers which you have, which is 5, to get 2.4.
We have that The mean absolute deviation of the set of data. 2, 3, 5, 7, 9 is
[tex]\sigma=2.24[/tex]
From the question we are told
Find the mean absolute deviation of the set of data. 2, 3, 5, 7, 9
Generally the equation for the mean absolute deviation is mathematically given as
[tex]\sigma={\frac{\sum(x-u)}{N}[/tex]
Where
[tex]x=\frac{2+3+5+7+9}{5}\\\\x=5.2[/tex]
Therefore
[tex]\sigma={\frac{\sum(x-u)}{N}\\\\\sigma=\frac{3.2+2.2+0.2+1.8+3.8}{5}\\\\\sigma=2.24[/tex]

miguel builds a model airplane with the scale 1in = 6ft . if the model is 9.3 inches long how long was the actual airplane ?
answer : 54.2 ft
Answer:
55.8 ft
Step-by-step explanation:
This seems simpler than it is.
So since it's going from inches to feet, we have to first know the conversion rate of inches to feet which is simple, 12 inches=1 foot. So now we have to figure out how many inches is 6 ft, so 12*6 equals 72. So knowing the scale, we can just do 9.3 *72=669.6. But if we want to know how long the actual airplane was in feet, then we have to do 669.6/12 which equals 55.8
Another way we could do it is by doing 9.3*6. This works because if you multiply something 12 and then divide it by 12, it just becomes 1. But doing this, you can't find the actual airplanes length in inches.

an integer is 10 times the difference of a rational number and 5. If the value of the integer is 124, what is the value of the rational number?
Answer:
17.4
Step-by-step explanation:
Given the question :
an integer is 10 times the difference of a rational number and 5. If the value of the integer is 124, what is the value of the rational number?
An integer = 124 is 10 times the difference of a rational number and 5
Let the rational number be r
Hence,
124 = 10 × (r - 5)
124 = 10r - 50
124 + 50 = 10r
174 = 10r
Divide both sides by 10
174 / 10 =. 10r / 10
17.4 = r
r = 174 / 10 or 17.4

A map of a rectangular park has a length of 4 inches and a width of 6 inches. It uses a scale of 1 inch for every 30 miles. What is the actual area of the park?
Answer:
Actual area = 21600 Sq.miles
Step-by-step explanation:
We are given;
length; L = 4 inches
Width; W = 6 inches
The scale of the map; 1 inch for every 30 miles i.e. 1 : 30
Since the scale is 1:30, let's find the find the actual dimensions and then the actual area
For the Length,
Since 1 inch represents 30 miles,
Then, 4 inches = (4 × 30)/1 = 120 miles
For the width;
Since 1 inch represents 30 miles,
Then,6 inches = (6 × 30)/1 = 180 miles
Therefore, the actual dimensions are 120 miles and 180 miles
Now, formula for area of rectangle = length × width
Thus;
Actual area = 120 × 180
Actual area = 21600 Sq.miles

Answer:
Your correct answer is option B.
Step-by-step explanation:
Option b is the highest number in the options. and, the dot on the number line is closest to the 5. Therefore, your correct answer is option B.
√24 can be the number shown on the number line. Hence, option A is the right choice.
What is a number line?The integers are put at equal intervals on number lines, which are horizontal straight lines. A number line can depict all of the numbers in a series. At both ends, this line continues endlessly.
How do we solve the given question?In the question, we are given a number line showing a point between 4 and 5, which is very close to 5.
We analyze all the given options for a number similar to the number marked on the number line to get the correct option.
To remember, 4 = √16, and 5 = √25
A. √24: falls between 4 and 5 (∵ √16 < √24 < √25). And also √24 is very close to 5 (√25).B. √27: does not fall between 4 and 5 (∵ √27 > √25).C. √20: falls between 4 and 5 (∵ √16 < √20 < √25).

For all integer values of x and constant k, if (x-k)(x-5)=x^2-9x+20, what is the value of K?
A) -5
B) -4
C) 4
D) 10
E) 12
============================
Work Shown:
Expand out the left hand side
(x-k)(x-5)
x(x-5)-k(x-5)
x^2-5x-kx+5k
Note that the constant term here is 5k. Yes k seems like a variable, but it's actually a constant. Once we know k, we can replace it to get a fixed number. In this case, k = 4 since 5k = 5*4 = 20 to have it match with the 20 at the end of x^2-9x+20
For the x terms, we have -5x-kx = -5x-4x = -9x which matches with the middle term of x^2-9x+20
Therefore,
(x-k)(x-5) = x^2-9x+20
updates to
(x-4)(x-5) = x^2-9x+20
The -4 and -5 multiply to 20, and they also add to -9. This helps confirm we have the right k value.

Fernando's lawn is 30 meters wide. His neighbor's lawn is 50 meters wide. In centimeters, what is the difference in width between the two lawns? (hint: 1 m = 100 cm)
Answer:
The difference in width is 2000 cm.
Step-by-step explanation:
The wideness of Fernando’s lawn = 30 meters
Neighbour’s lawn = 50 meters
Now we have to find the difference in width that can easily find out by subtracting the width of Fernando’s lawn from the neighbor’s lawn.
The difference in width = neighbor's lawn - Fernando's lawn
The difference in width = 50 - 30
The difference in width = 20 meters
The difference in width = 20 meters ×100 = 2000 cm.
