what are the constant of proportionality for these two tables​

Answer: 9

Step-by-step explanation: The common denominator will be the least common multiple for the two denominators.

To find the least common multiple or lcm of 3 and 9, begin by listing the first few multiples for each number.

Multiples of 6

1 × 9 = 9

2 × 9 = 18

3 × 9 = 27

Notice that we skipped 0 × 9 in our list of multiples. That's because 0 × 6 is 0 according to the zero property of multiplication and our least common multiple can't be 0.

When listing the multiples of 3, it's a good idea to keep an eye on the list of multiples for 9 so that we will notice when we find a least common multiple.

Multiples of 3

1 × 3 = 3

2 × 3 = 6

3 × 3 = 9

Notice that in both lists, we have the least common multiple which is 9.

Therefore, the least common denominator of 9 and 3 is 9.

Answer:

width =5m

length=18m

Step-by-step explanation:

w=x

l=3x+3

perimeter =2(l+w)

46=2(x+3x+3)

46=2(4x+3)

46=8x+6

46-6=8x

40=8x

x=40/8

x=5

l=3x+3=3*5+3=15+3=18

Final answer:

To find the length and width of a rectangle with a given perimeter, use algebra to solve for the width first, then use that value to find the length. The width is 5 meters and the length is 18 meters based on the given perimeter and the relationship between length and width.

Explanation:

The perimeter of a rectangle is given by the formula P = 2l + 2w, where P is the perimeter, l is the length and w is the width. According to the problem, the perimeter is 46 meters, and the length is 3 meters more than 3 times the width. Therefore, we can express the length as l = 3w + 3. Let's set up the equation using the perimeter formula:

Now that we've found the width to be 5 meters, we can find the length:

The width of the rectangle is 5 meters and the length is 18 meters.

a) He will earn $584 for working 36 hours.

b) He will earn $656 for working 39 hours.

c) He will earn $728 for working 42 hours.

Step-by-step explanation:

Amount per hour = $16

Time and a half means 1.5 times more than the original payment.

Therefore, above 35 hours, the earning for one hour,

Extra time per hour = 16*1.5 = $24

A) 36 h

For the first 35 hours, he will get $16 per hour, therefore,

Amount of 35 hours = [tex]35*16= \$560[/tex]

Amount of one hour = $24 (as calculated above)

Total = 560+24 = $584

He will earn $584 for working 36 hours.

B) 39 h

39 h = 35h + 4h

Amount of 35 hours = $560

Amount of extra 4 hours = $24*4 = $96

Total = 560+72 = $656

He will earn $656 for working 39 hours.

C) 42 h

42 h = 35h + 7h

Amount of 35 hours = $560

Amount of extra 7 hours = 24*7 = $168

Total = 560+168 = $728

He will earn $728 for working 42 hours.

Answer:

"To the nearest year, it would be about 9 years"

Step-by-step explanation:

11c)

This is compound growth problem. It goes by the formula:

[tex]F=P(1+r)^t[/tex]

Where

F is the future amount

P is the present (initial) amount

r is the rate of growth, in decimal

t is the time in years

Given,

P = 20,000

r = 8% = 8/100 = 0.08

F = double of initial amount = 2 * 20,000 = 40,000

We need to find t:

[tex]F=P(1+r)^t\\40,000=20,000(1+0.08)^t\\2=(1.08)^t[/tex]

To solve exponentials, we can take Natural Log (Ln) of both sides:

[tex]2=(1.08)^t\\Ln(2)=Ln((1.08)^t)[/tex]

Using the rule shown below we can simplify and solve:

[tex]Ln(a^b)=bLn(a)[/tex]

We can write:

[tex]Ln(2)=Ln((1.08)^t)\\Ln(2)=tLn(1.08)\\t=\frac{Ln(2)}{Ln(1.08)}\\t=9.0064[/tex]

To the nearest year, that would be about 9 years

Answer:

Step-by-step explanation:

$33,284 * 1.045 = $34781.78

The new salary will be $34781.78

Last year salary = $33284

Annual raise = 4.5%

Therefore, based on the above figures the new salary will be:

= $33284 + (4.5% × $33284)

= $33284 + (0.045 × $33284)

= $33284 + $1497.78

= $34781.78

Based on the calculation above, the new salary will be $34781.78

Answer:

The answer is 16.4%

Step-by-step explanation:

The total decrease of price percentage is 16.4% when the price was decreased by 12% .

Evaluating decrease price :

The first discount reduces the price to (100 - 12)%

                                  = 88%  which is 0.88 times the original price.

The second discount reduces the already discounted price to

                                    (100 - 5)% =

                    95% of the discounted price

(0.95 times the discounted price). Get 2 discounts combined

Final Price = (0.95)(0.88) x (Original Price)

                            = 0.836 x (Original Price)

This is 83.6% of the original price, so the total discount rate is

                               (100 - 83.6)%

                                     = 16.4%.

Answer:

Let the number of packets be x and the number of boxes be y.

Then, the formula is 6x + 15y

Step-by-step explanation:

The formula for the total number of buttons Nomusa buys, represented by t, in terms of the number of packets, p, and boxes, b, she buys is: t = 6p + 15b.

In this mathematical context, let's suppose that Nomusa buys p packets and b boxes of buttons. The total number of buttons can be represented by the letter t. Since there are 6 buttons in a packet and 15 buttons in a box, the total number of buttons Nomusa buys will be the sum of all buttons in the packets and boxes she buys. Thus, the formula in terms of p (packets) and b (boxes) will be: t = 6p + 15b.

Step-by-step explanation:

we know that

The formula to calculate the midpoint between two complex numbers (a+bi) and (c+di) points is equal to

[tex](\frac{a+c}{2})+(\frac{b+d}{2})i[/tex]

we have

(1+9i) and (5-3i)

substitute the given values

[tex](\frac{1+5}{2})+(\frac{9-3}{2})i[/tex]

[tex]3+3i[/tex]

Final answer:

The midpoint of the complex numbers 1+9i and 5-3i is calculated using the average of their real and imaginary parts, resulting in the midpoint of 3 + 3i.

Explanation:

To find the midpoint of two complex numbers, 1+9i and 5-3i, we use the midpoint formula for complex numbers which is the average of the real parts and the average of the imaginary parts separately. The formula for the midpoint M is given by:

M = ½(x1 + x2) + ½(y1 + y2)i

For our complex numbers, the real parts are 1 and 5, and the imaginary parts are 9 and -3. Applying the midpoint formula, we get:

M = ½(1 + 5) + ½(9 - 3)i = ½(6) + ½(6)i = 3 + 3i

Therefore, the midpoint of the complex numbers 1+9i and 5-3i is 3 + 3i.

Final answer:

The balance in the savings account after 5 years, with quarterly compounded interest, will be $2,699.80.

Explanation:

To find the balance after 5 years when the interest is compounded quarterly, we can use the formula for compound interest:

[tex]A = P(1 + r/n)^(nt)[/tex]

Where:
- A is the final amount
- P is the principal amount (initial investment)
- r is the annual interest rate (in decimal form)
- n is the number of times the interest is compounded per year
- t is the number of years

Plugging in the given values:

[tex]A = $2,000(1 + 0.06/4)^(4*5)[/tex]

[tex]A = $2,000(1.015)^20[/tex]

A = $2,000 * 1.3499

A ≈ $2,699.80

After 5 years, the balance in the savings account will be approximately $2,699.80.

Answer:

The needed line equation is :  x + y + 2 = 0

Step-by-step explanation:

The slope m of the given line equation = -1

The points through which the line passes  is (1,-3).

Now,as we know:

The POINT SLOPE form of the equation with point (x0,y0) is given as:

y - y0 = m (x-x0)

So, the equation if line q=with m = -1 and (x0,y0) = (1,-3) is given as

y  - (-3)  = -1( x  - 1)  

or, y + 3 = 1 -x

or, x + y + 2 = 0

Hence, the needed line equation is :  x + y + 2 = 0

Step-by-step explanation:

The system of equations are p = 150 + 5n and p = 15n

Solution:

Given that, The Parks and recreation department in your town offers a season pass for $150.  

With the season pass you pay $5 per session to use the town's tennis courts.  

Without the season pass you pay $15 per session to use the tennis courts.

We have to write a system of equations to represent the situation

Now, let the number of sessions be "n" and total paying amount be "p"

Then in case of taking season pass  

total amount = season pass cost + $5 per session

p = 150 + 5 x n  

p = 150 + 5n  

And in case of no season pass

total amount = 15 per session

p = 15 x n  

p  = 15n

Hence, the system of equations are p = 150 + 5n and p = 15n

Final answer:

To represent the cost of using the town's tennis courts with and without a season pass, we use two equations: C = 150 + 5x for with a pass, and C = 15x for without a pass, where C is the total cost and x is the number of sessions.

Explanation:

The Parks and Recreation Department offers two options for using the town's tennis courts: with a season pass and without a season pass. We need to write a system of equations to represent the cost for each option depending on the number of sessions a person attends.

Equations

With Season Pass: C = 150 + 5x

Without Season Pass: C = 15x

In these equations, C represents the total cost of using the tennis courts for a given number of x sessions. For the pass option, there is an upfront cost of $150 plus $5 per session. Without the pass, each session costs $15.

These equations can help determine the point at which purchasing a season pass becomes more cost-effective than paying per session.

The width and length of the rectangle are 7 meters and 10 meters, respectively, as determined by using algebraic expressions to relate the given perimeter with the width and length formulas.

To solve for the length and width of a rectangle given the perimeter, we can use algebra. Since we know the length (L) is 4 meters less than twice the width (W), we can write this relationship as L = 2W - 4. The formula for the perimeter (P) of a rectangular shape is P = 2L + 2W. We are given that the perimeter is 34 meters.

Substituting the expression for L into the perimeter formula gives us:

Since the perimeter is 34 meters, we set 6W - 8 = 34.

Now, we find the length using the expression L = 2W - 4:

Therefore, the width is 7 meters and the length is 10 meters.

Answer:

212.9 days

Step-by-step explanation:

The bacteria culture initial population is 25 represented by Po and the population after t days is represented by P(t).

Using growth formula:

P(t) = Po ( 1 + r)^t where r is rate in percent and t is time in days

r = 1.28%, P(t) = 375, and Po = 25

substituting this values into the equation above yields

375 = 25 (1 + 1.28/100)^t

375÷25 = ( 1 + 0.0128)^t

15 = (1.0128)^t

take logarithm of both sides

log 15 = log (1.0128)^t remember the law log a^b = b log a

applying the same law gives

log 15 = t log 1.0128

divide both side by log 1.0128

log 15 ÷ log 1.0128 = t log 1.0128 ÷ log 1.0128
