Answer: $27.20
Step-by-step explanation:
She bought a blouse for 20% off so it means that she paid 80% of the original price.We can then set up the equation
80% of x = 21.76 where x is the original price so solve for x
0.8x = 21.76
x = 27.20
Which means the original price is $27.20

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.

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
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.

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.

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

S = 2πr² + 2πrh

That's
2πrh = S - 2πr²
Divide both sides by 2πr to make h stand alone
That's
[tex] \frac{2\pi rh}{2\pi r} = \frac{S - 2πr²}{2\pi r} [/tex]We have the final answer as

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]
Therefore
