What is the constant proportionality in the table below?

Answer:

6 min

Step-by-step explanation:

given that the rate for the first student is 10 min per wall

we can express this in wall per minute by taking the reciprocal

hence student 1's unit rate = 1/10 wall per min

similarly, we can express student 2's unit rate as 1/15 wall per min.

if we add up the two, we will get the amount of wall painted by two people working together per min

amount of wall painted per min by 2 people

= wall per min of person 1 + wall per min of person 2

= 1/10 + 1/15

= 3/30 + 2/30

= 5/30

= 1/6 wall per min.

to convert this to minutes per wall, we take the reciprocal:

number of minutes that both people will take to paint the wall

= 1 / (1/6)

= 6 min per wall  (answer)

Answer:

Your answer would be x = 63

Step-by-step explanation:

What I would do first is to isolate the -1/9x, which means I would subtract 17 on each side, giving me -1/9x = -7

Next I would multiply -9 (which is the inverse of -1/9) on both sides, negating the negative sign and making 63 positive, and thus isolating x as well.

Given:

Initial amount = 8

To find next week's amount, we multiply this week's amount by 4.

To find:

A formula that gives the amount A after T weeks.

Solution:

We have,

Initial amount = 8

According to the question,

Amount of next week = 4 × Amount of this week

Amount after one week is

[tex]A=4\times 8[/tex]

Amount after two week is

[tex]A=4\times (4\times 8)[/tex]

[tex]A=4^2\times 8[/tex]

Amount after T week is

[tex]A=4^T\times 8[/tex]

[tex]A=8(4)^T[/tex]

Therefore, the required formula that gives the amount A after T weeks is [tex]A=8(4)^T[/tex].

Answer:

No (The linear model did a very bad job of approximating the data.)

I am so sorry if this in incorrect.

The percentage illumination of the moon's surface is not a linear function of day

From the complete question, the dataset can be represented using the following table:

Days   Percentage Illumination

1           2%

2          6%

3          50%

4          100%

Notice that as the number of days increase by 1, the percentage illumination of the moon increase at different intervals

This means that the percentage illumination is not a linear function of day

Step-by-step explanation:

You must count the distance between so if you look at where it lines up perfect -3,0 up to 2 the distance is 5

Answer:

Step-by-step explanation:

The slopes are same and y-intercepts are:

Since we have:

We can find the value of k:

Answer is k = - 5

Answer:

the answer is y= 5/2 x +5

Answer:

y = [tex]\frac{5}{2}[/tex] x + 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}=x_{1} }[/tex]

with (x₁, y₁ ) = (- 2, 0) and (x₂, y₂ ) = (0, 5)

m = [tex]\frac{5-0}{0+2}[/tex] = [tex]\frac{5}{2}[/tex]

The line crosses the y- axis at (0, 5 ) ⇒ c = 5

y = [tex]\frac{5}{2}[/tex] x + 5 ← equation of line

Answer:

15) slope=-4  y-intercept is 3   equation is y=-4x+3

16) slope=0  y-intercept is -4   equation is y=0x-4

17) slope=2  y-intercept is 4   equation is y=2x+4

18) slope=1  y-intercept is 4   equation is y=1x+4

Answer:

m<1 = 75

m<2 = 55

m<3 = 55

Step-by-step explanation:

Well <1 + 50° is vertical to 125 so do this

<1 + 50 = 125 (subtract 50 on both sides)

<1 = 75

Now <1 + <2 + 50° = 180

We know what <1 is so..

75 + <2 + 50 = 180 (collect like terms)

125 + <2 = 180 (subtract 125 on both sides)

<2 = 55

Since <2 and <3 are vertical that means they equal the same so

<3 = 55

Answer: check explanation for the solution

Step-by-step explanation:

A business that offers services to people by providing many amusement and fun with gate fees

The algebraic equations to be used is the general linear equation

Y = MX + C

Where

Y = total income or money realised

M = rate or price rate

X = number of goods or services

C = flat rate or gate fees

The business can also operate differently by using exponential equation

A = P(1 + R%)^t

Where

A = profit

P = capital

R = rate

t = time

Answer:

The price per inch is $0.26.

Step-by-step explanation:

There are 12 inches in 1 foot.

First, we need to calculate what the cost is per foot.

18.72 / 6 = 3.12

From this answer, we have to divide by 12 to calculate what the price is per inch.

3.12 / 12 = 0.26

Answer:

1/3

Step-by-step explanation:

When dividing fractions flip and multiply.

So 12 would become 1/12

and 1/4 would become 4/1

Now multiply

[tex]\frac{1}{12}*\frac{4}{1}= \frac{4}{12} = \frac{1}{3}[/tex]

So the answer is 1/3

When dividing fraction remember to flip then multiply much easier that way!
