The sum of three numbers is 21. The second number is two more than twice the first number. The second number is three times the third number. What are the numbers?

Answers

Answer:

The numbers are:

5, 12 and 4

Step-by-step explanation:

a + b + c = 21       Eq. 1

b = 2a +2             Eq. 2

b = 3c                   Eq. 3

From Eq. 2:

b - 2 = 2a

(b-2)/2 = a              Eq. 4

From Eq. 3:

c = b/3                     Eq. 5

Replacing Eq. 4 and Eq. 5 in Eq. 1:

(b-2)/2 + b + b/3 = 21

3(b-2)/6 + 6b/6 + 2b/6 = 126/6

3(b-2) + 6b + 2b = 126

(3*b + 3*-2) + 8b = 126

3b - 6 + 8b = 126

11b = 126 + 6

11b = 132

b = 132/11

b = 12

from Eq. 4

(b-2)/2 = a

(12-2)/2 = a

10/2 = a

a = 5

from Eq. 5

c = b/3

c = 12/3

c = 4

Check:

from Eq. 1

a + b + c = 21

5 + 12 + 4 = 21

What is the net pay?
27.25 hours worked
$5.95 an hour
Federal tax deduction $13.29
Social Security deduction $9.65
Other deductions $6.37
$122.69
$132.83
$159.41
$162.14

Answers

Net pay for the individual is $132.83

Given that;

Number of hour worked = 27.25

Per hour pay = $5.95

Federal tax deduction = $13.29

Social Security deduction = $9.65

Other deductions = $6.37

Find:

Net pay

Computation:

Net pay = [(27.25)(5.95)] - 13.29 - 9.65 - 6.37

Net pay = [(27.25)(5.95)] - 13.29 - 9.65 - 6.37

Net pay = 162.1375 - 29.31

Net pay = 132.8275

Net pay = $132.83

Both the ranges and the interquartile ranges for the data sets are the same.
Neither the ranges nor the interquartile ranges for the data sets are the same.
The interquartile ranges for the box plots are the same, but their ranges are different.
The ranges for the box plots are the same, but their interquartile ranges are different.

Answers

Answer:

to find range of interquartile sets of data

you see 5 vertical lines 1 is start point 2 is start of 2nd quartile 3 is start of 3rd quartile and also represents the median.  the 4th start of 4th quartile and 5th is very end point.

Therefore the interquartile is from start line 2 to start line 4

apply to each by if it says 10 and 34 then we show workjings 34-10 = 24 and that is the range once we deduct data from each other.

Therefore full range is start line 1 to end line 5

if this says 2 to 45 then full range is 45-2 = 43 and apply to each boxplot.

Order the following numbers from least to greatest 1/2, -0.67, -2/5, 0.54, -1.2

Answers

Answer:

-1.2; -0.67; -2/5; 1/2; 0.54

Step-by-step explanation:

because there are negative numbers, we put those first. the bigger the number behind the negative is, the smaller it is

-1.2 is the only negative with a ones place so it goes first

-0.67 comes right before -2/5, or -0.4

then we move into the positive numbers: 1/2 and 0.54

1/2 is 0.5, which is less than 0.54

so the order is -1.2; -0.67; -2/5; 1/2; 0.54

Describe the translation in each function. Then graph the function.

Y=x^2 + 4

Please give a detailed answer I don't understand

Answers

It's a Quadratic that doesn't have any real roots as the parabola doesn't cross the x-axis.

For graphing:

If you're familiar with the parabola of y=x^2, then you could graph that but just translate it upwards by +4 on the y such that f(x)+4 will be equal to it.

If you aren't, then we know the y-intercept is 4, and that's also the point of the minimum point of the curve. If I were you, I'd write a table of some of the integer values:

x y

-2 8

-1 5

0 4

1 5

2 8

The value of y is the same for x and -x as anything squared is positive.This means that there is a line of symmetry in the y-axis.

This then makes it much easier to graph, simply place these points on the graph and make sure the curve is exponential. This means the gradient (steepness) gets greater the bigger the value of x.

Given the function f(x) = 2x, evaluate f (3).

Answers

Answer:

Step-by-step explanation:

Given that f(3), x=3.

Since f(x) = 2x, we plug in 3 for x, and get 2 times 3. Therefore, the answer comes out to 6.

When f(3)

Then we have:

3=2x

Now we divide by 2 (on both sides)

We are asked to find the distance Louise cycled.

Speed Louise cycled = 12 mph

Time = 11: 30 am to 12 : 15 pm

= 45 minutes

Convert 45 minutes to hour

60 minutes = 1 hour

45 minutes = 3/4 hour

Speed = Total distance ÷ Total time taken

Distance = Speed × Time

= 12 mph × 3/4 hour

Reiko started a business selling home medical supplies. She spent $6500 to obtain her merchandise, and it costs her $550 per week for expenses. She earns $900 per week for general expenses.
What is the minimum number of weeks it will take for Reiko to make a profit?

a.) 900w ≥ 6500 + 550w
b.) 900w < 6500 + 550w
c.) 900w > 6500 + 550w
d.) 550w > 6500 + 900w

Answers

Answer:

C

Step-by-step explanation:

$6500 is a one time purchase so there is no variable attached.

$550 and $900 per week is reoccurring so there will be a variable attached.

Since $900 is what she is making each week, this will be separate from her costs (can eliminate D).

To make a profit, her amount earned will need to be greater than her expenses, so the answer is C.

C(t ) = represents the total cost relative to the t  number of tickets used

t = number of tickets used to play games

1.25 = cost per ticket to play games
