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.

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.

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.

The expression for the amount of money to buy 'b' books is

(A.) 7.50 times b

if the camp leader has 12 campers the amount of money will be$90.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, A camp leader buys a book for each of her campers. She spends $7.50 on each book.

Assuming he bought 'b' no. of books.

∴ The expression for the amount of money to buy 'b' books is 7.50b.

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

The mean absolute deviation of the set of data. 2, 3, 5, 7, 9 is

Maria Gomez's total pay for the week when she works 45 hours will be $575.70.

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

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.

============================

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.

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

Answer:

The number of balloons varies directly with the number of tables. The two variables are directly proportional. The relationship of balloons to tables is the ratio 5:1, where 5 is the constant of variation. Use the equation y = kx, where k is the constant of variation resulting in the equation y = 5x.
