The percentage of milk in the resulting mixture is 19.44% and this can be determined by using the unitary method.
Given :
John adds 2 oz of milk to an 18 oz cup of coffee that is 10% milk.
The following steps can be used to determine the percentage of milk in the resulting mixture:
Step 1 - The unitary method can be used to determine the percentage of milk in the resulting mixture.
Step 2 - Given that 18 oz cup of coffee has 10% of the milk that is:
[tex]=\dfrac{18}{100}\times 10[/tex]
= 1.8 oz of milk
So, the 18 oz cup of coffee contains 1.8 oz of milk.
Step 3 - It is given that 2 oz of milk is added in 18 oz cup of coffee. So, the total mixture becomes 20 oz.
Step 4 - So, an 20 oz cup of coffee there 3.5 oz of milk.
Step 5 - If 1.8 oz is 10% then 3.5 oz is:
[tex]=\dfrac{3.5}{1.8}\times 10[/tex]
= 19.44 %
The percentage of milk in the resulting mixture is 19.44%.

The difference of the given expression is 5x/12 - 5.
The given expressions are (3/4 x-1) and (1/3 x+4).
What is the subtraction of expressions?To subtract an algebraic expression from another, we should change the signs (from '+' to '-' or from '-' to '+') of all the terms of the expression which is to be subtracted and then the two expressions are added.
Here, (3/4 x-1) - (1/3 x+4)
= 3/4 x -1 -1/3 x -4
= (3/4 x - 1/3 x) -1-4
= 9/12 x - 4/12 x) - 5
= (9-4)/12 x - 5
= 5x/12 - 5

write the algebraic rule to describe the transformation. translation: 1 unit the left and 2 units up
write the algebraic rule to describe the transformation. Translation: 5 units right and 2 units up
Answer:
Step-by-step explanation:
In Exercises 11 and 12, describe the transformation of the graph of the ... 4x2 + 5; horizontal stretch by a factor of 2 and a translation 2 units up, ...
The algebraic rules are
(x, y) → (x - 1, y + 2)
(x, y) → (x + 5, y + 2)
What is translation?It is the movement of the shape in the left, right, up, and down directions.
The translated shape will have the same shape and shape.
There is a positive value when translated to the right and up.
There is a negative value when translated to the left and down.
We have,
For a translation of 1 unit to the left and 2 units up,
The algebraic rule.
(x, y) → (x - 1, y + 2)
This means that each point (x, y) in the original figure is transformed into a new point (x - 1, y + 2) in the translated figure.
Now,
For a translation of 5 units to the right and 2 units up,
The algebraic rule.
(x, y) → (x + 5, y + 2)
This means that each point (x, y) in the original figure is transformed into a new point (x + 5, y + 2) in the translated figure.
Thus,
The algebraic rules are:
(x, y) → (x - 1, y + 2)
(x, y) → (x + 5, y + 2)

A doctor's office found that a lower outside temperature did not indicate a change in the number of appointments made. What can we determine from this information? 1.There is no correlation between outside temperature and number of appointments made. 2.There is a correlation between outside temperature and number of appointments made. However, there is no causation. This is because there is likely an increase in the number of appointments made with a decrease in the temperature outside. 3.There is a correlation between outside temperature and number of appointments made. There may or may not be causation. Further studies would have to be done to determine this.
Answer: 1, There is no correlation between outside temperature and number of appointments made.
Step-by-step explanation: It would be 1 because in the problem it states that even though temperatures were lower outside, their number of appointments had not changed. Because the number of appointments had not changed, there is no correlation between the temperature outside and number of appointments made.
Answer:
no correlation

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
a)
The hair length is about 8 cm
b)
It takes about 18 months.
c)
it takes about 40 months.
What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
The coordinates from the graph:
(2, 1), (3, 1.5), (4, 2), (6, 3), and (8, 4)
Where the x-axis is the number of months and the y-axis is the length of the hair in inches.
Now,
1 inch = 2.54 cm
3 inches = 3 x 2.54 = 7.62 cm
The hair length after 6 months.
= (6, 3)
= 3 inches
= 7.62 cm
Now,
6 months = 3 inches
Multiply 8/3 on both sides.
8/3 x 6 months = 8 inches
16 months = 8 inches
Now,
From the graph, we see that,
(8, 4)
This means,
In 4 months the length of the hair is 4 inches.
8 months = 4 inches
Multiply 5 on both sides.
40 months = 20 inches
Thus,
a)
The hair length is about 8 cm
b)
It takes about 18 months.
c)
it takes about 40 months.

Gerard is calculating the area of a composite figure. The figure is made up of a square with side lengths of 6 centimeters (cm) and a triangle with a base of 6 cm and a height of 3.5 cm.
Gerard multiplies 6 by 3.5 to get that the area of the figure is 21 cm2, which is not the correct area.
Which statement correctly describes how Gerard could have found the correct answer?
-He should have found the area of the square, 36 cm2, and added it to the area of the triangle, 27 cm2, to get 63 sq. cm.
-He should have added 6 to 3.5 to get 9.5 sq. cm.
-He should have multiplied 21 by 12 to get 10.5 sq. cm.
-He should have found the area of the square, 36 cm2, and added it to the area of the triangle, 10.5 cm2, to get 46.5 sq. cm.
