Nora took 10 bottles of water to a picnic. Of these bottles of water, she and her friends opened a certain number of bottles, b. What expression can be used to determine the number of unopened bottles at the end of the picnic?

Answers

Answer 1

Answer:

10 - B = U

Step-by-step explanation:

U stands for the unopened bottles

for example if they opened 3 bottles it would be 10 - 3 = U (unopened bottles)

The value of U is 7 because the 10 bottles of water minus the 3 bottles they opened it would equal 7.

therefore the equation 10 - B = U shows the amount of unopened bottles

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?

Answers

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

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?

Answers

Reg. Pay = $12.12 x 40hrs
Ot pay = $12.12 x 1.5 x 5 hrs

Add Reg Pay + OT

$484.80 + $90.90
= $575.70

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

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

Answers

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

Answers

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.

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)

Answers

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.
