what is the constant of proportionality?

Answer:

12.91

Step-by-step explanation:

We are told that Each woman's total is modeled with this expression:

9 + 1.34 + 1/2(3.50 + 1.74)

To solve this we will use the BODMAS acronym.

So the first operation will be to solve what's in the bracket to give;

9 + 1.34 + 1/2(5.14)

Let's now carryout the multiplication of the bracket to give;

9 + 1.34 + 2.57

Using the addition operation now gives us: 12.91

Answer: First, add the decimals in the parentheses. Next, multiply that number by 0.5. Finally, add all the decimal numbers.

Answer:

A. √34

Step-by-step explanation:

Lets find the decimal form of al the answer choices (round to the nearest hundredth).

√34 ≈ 5.83

√24 ≈ 4.90

√68 ≈ 8.25

√44 ≈ 6.63

On the number line, we see that the red dot is between the numbers 5 and 6. The only number that is between those numbers is 5.83 which is √34.

Best of Luck!

Answer:

15.4 lbs

Step-by-step explanation:

Since the average of the top five is 13.3 this says that:

total weight of all the fish / 5 = 13.3 lbs

Therefore, the total weight of all five fish is equal to:

13.3 * 5 = 66.5

With this number, I subtracted all the other weights and found that the missing weight was:

15.4lbs.

Therefore, Wayne S. had the biggest fish weighing 15.4lbs

Answer:

15.4

Step-by-step explanation:

(14.2 + 13.4 + 12.1 + 11.4 + X) / 5 = 13.3

(51.1 + X) / 5 = 13.3

Cross:

51.1 + X = 66.5

then X = 66.5 - 51.1

= 15.4

Answer:

4 7/17 yeards or 4.412 yards approximately if the map shows the distance as 3 inches.

Step-by-step explanation:

The actual distance of the Harper from the school = 50 yards. According to the map, the distance from the school = 34 inches. We could say 34 inches represents 50 yards. So, 1 inch could be represented by 50/34 = 25/17 yards. In order to find the actual length of 3 inches in yards, we need to multiply 1 inches value of yards by 3.Therefore, 3 inches = 3* 25/17 = 75/17 = 4 7/17 yeards in decimals 4.412 yards approximately. Therefore,  Harper from home is  4 7/17 yeards or 4.412 yards approximately if the map shows the distance as 3 inches.

Linear equation for the monthly cost of the cell plan is [tex]10+0.15x[/tex]

Step-by-step explanation:

Let u denotes a flat monthly fee and v denotes amount charged per minute.

As the monthly cost is $71.50 if a customer uses 410 minutes,

[tex]71.50=u+410v[/tex]     (i)

As the monthly cost is $118 if a customer uses 720 minutes,

[tex]118=u+720v[/tex]       (ii)

Subtract (i) from (ii)

[tex]118-71.50=u+720v-u-410v\\46.5=310v\\v=\frac{46.5}{310}\\ v=0.15[/tex]

Put [tex]v=0.15[/tex] in (i)

[tex]71.50=u+410(0.15)\\71.50=u+61.5\\u=71.50-61.5\\u=10[/tex]

As x denotes the number of monthly minutes used,

linear equation for the monthly cost of the cell plan is [tex]10+0.15x[/tex]

Answer:

6.5

Step-by-step explanation:

You divide.

So like 13 / 2 is 13 divided by 2 and is 6 remainder 1.

You can write this as 6 1/2.

1/2 is 0.5

So 13/2 is 6.5

Answer:

This means that, when the price of book from publisher is $60, the bookstore will sell it $88 to the students.

Step-by-step explanation:

Solution:

The cost of book from publisher = 40%

Sales tax = 7.5%

Price of books to the student = p(x) = 1.075x + 0.40x

Where, x is cost of book.

P (60) =?

We know that,

P(x) = 1.075 + 0.40

       = 1.475%

        =148

Given, Cost of book, x = 60

P (60) = 148 – 60

       = 88

This means that, when the price of book from publisher is $60, the bookstore will sell it $88 to the students.

Answer:

Step-by-step explanation:

3) diameter of penny = 19 mm

                          r = 19/2 = 9.5 mm

Area of penny = πr²

                        = 3.14 * 9.5 * 9.5

                         = 283.385

                         = 283.39 mm²

Diameter of nickel = 21 mm

                          r = 21/2 = 10.5 mm

Area of nickel  = πr²

                         = 3.14 * 10.5 *10.5

                        = 346.185

                        = 346.19 mm²

346.19 - 283.39 = 62.8 mm²

Area of Canadian nickel is greater than Canadian penny by 32.6 mm²

4)  r = 12 mm

Area of circle = πr²

                      = 3.14 * 12 * 12

                       =  452.16 mm²

5) r  = 20 cm

Area of circle =  πr²

                      = 3.14 * 20 * 20

                      = 1256 cm²

Answer:

she has 45 muffins left

her family took 18 muffins

crystal ate 9 muffins

Step-by-step explanation:

54 × 1/6 = 9

54 - 9 = 45

45 x 2/5 = 18

45 - 18 = 27

27 x 1/3 = 9

Answer:3(-4f-g(to the power of -2)

Step-by-step explanation:

3(-fx4-g(to the power of -2) reorder and get solution.

Answer:

-12f + 6g

Step-by-step explanation:

f x -4 then 3 x -4f which you get -12f.

g x -2= -2g then -2g x 3= -6g.

Then we take the subtraction sign in the middle and make the equation simpler.

Answer:

12, 20

Step-by-step explanation:

Let the two numbers be x and y, where x > y

According to the given information:

x + y = 4(x - y)

x + y = 4x - 4y

y + 4y = 4x - x

5y = 3x

[tex] y = \frac{3}{5}x.... (1)[/tex]

Since, one number exceeds the other by 8.

[tex] \implies x = y + 8\\\\

\implies y = x - 8.....(2)\\\\[/tex]

From equations (1) & (2)

[tex]x - 8 = \frac{3}{5} x \\ \\ 5(x - 8) = 3x \\ \\ 5x - 40 = 3x \\ \\ 5x - 3x = 40 \\ \\ 2x = 40 \\ \\ x = \frac{40}{2} \\ \\ \huge \purple{ \boxed{\implies x = 20}} \\ \\ \implies \: y = x - 8 = 20 - 8 \\ \\ \huge \pink{ \boxed{ \implies \: y = 12}}[/tex]
