Answer:
1.
Clean machine slope: 3/2
Sudz slope: 3/2
This means they rise and run at the same rate.
2.
y intercept of clean machine: 2
y intercept of sudz: 4
this tells us that the cost for sudz is higher per pound.
3.
Clean machine because 4 pounds at sudz costs 10 dollars, while 5.5 pounds at clean machine costs 10 dollars. You get more for less at clean machine.

What is the constant of proportionality for the relationship shown in the table? x 2 4 6 8 y 1 2 3 4
1/2
2
4
8
Answer:
[tex]k = \frac{1}{2}[/tex]
Step-by-step explanation:
Given
x 2 4 6 8
y 1 2 3 4
Required
Determine the constant of proportionality (k)
The relationship between x and y is:
[tex]y = kx[/tex]
When y = 1, x = 2;
So, we have:
[tex]1 = k * 2[/tex]
[tex]2 * k = 1[/tex]
Make k the subject
[tex]k = \frac{1}{2}[/tex]
Hence, the constant of proportionality is 1/2

In the figure, JKLM - EFGH Complete the following table
Note: 1) Figures not drawn to scale.
ii) Use slash to separate numerator and denominator, wherever needed.
Scale factor of JKLM to EFGH
Value of X
Value of Y
value of Z
Answer:
Step-by-step explanation:
Scale factor of JKLM to EFGH is 5/2.
Value of x = 27.5
What is scale factor?A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size.
Given,
JKLM ~ EFGH
Scale factor = JK/EF = 20/8 = 5/2
So, KL/GF = 5/2
x/11 = 5/2
x = 55/2
x = 27.5
There is scale factor of 5/2 from JKLM to EFGH.
27.5 is value of x.

Element X is a radioactive isotope such that every 90 years, its mass decreases by half. Given that the initial mass of a sample of Element X is 30 grams, how much of the element would remain after 12 years, to the nearest whole number?
Answer:
approximately 27 grams
Work Shown:
Half life formula
y = A*(0.5)^(x/H)
where,
A = starting amount = 30 grams
H = half life period = 90 years
x = number of years that pass by = 12
y = amount left over after x years
Let's plug the values for x, A and H into the formula to find y
y = A*(0.5)^(x/H)
y = 30*(0.5)^(12/90)
y = 27.3516746567466
y = 27 .... rounding to the nearest whole number

Someone please answer this question for me it’s my last one on my chapter test. It would be very appreciated
Answer:
We have the function:
[tex]P(t) = \frac{800 + 630*t}{20 + 0.09*t}[/tex]
a) The population of deer when t = 60 is equal to P(60)
We just need to replace t by 60 in the above equation:
[tex]P(60) = \frac{800 + 630*60}{20 + 0.09*60} = 1,519.7[/tex]
We can not have the 0.7 of a deer, so we could round this up to 1,520
So at t = 60, we would have around 1,520 deers.
b) The horizontal asymptote of P(t) = y is when the denominator of the function is equal to zero (this is when P(t) goes to infinity).
Then we need to find the value of t such that:
20 + 0.09*t = 0
20 = -0.09*t
20/-0.09 = t = -222.222...
The asymptote of P(t) is at t = -222.222...
Because in this case t is negative, the function will diverge to infinity and minus infinity.
c) We can ignore the asymptotes and only compute this for positive values of t.
To find the maximum, we first need to look at the zeros of the first derivative of P(t):
[tex]P'(t) = \frac{630}{20 + 0.09*t} - \frac{800 + 630*t}{(20 + 0.09*t)^2} *0.09 = 0[/tex]
[tex]\frac{800 + 630*t}{(20 + 0.09*t)^2} *0.09 = \frac{630}{20 + 0.09*t}[/tex]
[tex]\frac{800 + 630*t}{(20 + 0.09*t)^2} *0.09*(20 + 0.09*t) = 630[/tex]
[tex]\frac{800 + 630*t}{20 + 0.09*t} *0.09 = 630[/tex]
[tex](800 + 630*t) *0.09 = 630*(20 + 0.09*t)[/tex]
[tex]0.09*800 + 0.09*630*t = 630*20 + 630*0.09*t[/tex]
[tex]0.09*800 - 630*20 = 630*0.09*t - 0.09*630*t[/tex]
That last equation has no real solution, this means that we do not have a maximum. Then we will have a vertical asymptote
Then we can just look at the graph of the function (is below)
And you can see that we have a horizontal asymptote at y = 7000, then this will be the maximum number of deers.

Write an expression that it equivalent to 1/4x+1+3/4x-2/3-1/2x
Answer: =1/2x+1/3
Step-by-step explanation:
The equivalent expression is 1/2x+ 1/3.
What is Expression?A mathematical expression is a phrase that has a minimum of two numbers or variables and at least one mathematical operation. Let's examine the writing of expressions. The other number is x, and a number is 6 more than half of it. In a mathematical expression, this statement is denoted by the expression x/2 + 6.
Given:
1/4x+1+3/4x-2/3-1/2x
Now, solving the above expression
1/4x+1+3/4x-2/3-1/2x
= 1/4x + 3/4x - 1/2x + 1 - 2/3
= 4/4x - 2/4x + 1/3
= 2/4x + 1/3
= 1/2x + 1/3
Hence, the equivalent expression is 1/2x+ 1/3.
