Answer:
15 ml
Step-by-step explanation:
If we mix 1 part concentrate and 5 parts water, we have 6 parts in total.
To create 90ml medicine, <em>how many "6 parts" are there?</em>
 There would be 90/6 = 15 total "6 parts".
Each of the "6 parts's" 1 part is concentrate, so concentrate would be 1 * 15 = 15 ml.

The given angles are 95° and 135, and the value of x is 40.
<h3>What is the angle sum property?</h3>
The angle sum property of a triangle states that the sum of the interior angles of a triangle is 180 degrees.
The given angles are 95° and 135.
Let's consider the adjacent angle of 135 to be z.
So, as we can see that both angles make a linear pair.
z + 135 = 180
z = 180 - 135
z = 45
Let's consider the interior angle to be y.
then,
y = 95 ( vertically opposite angle)
Now, The angle sum property 
x + y + z = 180
x = 180 - 95 + 45
x = 40
Thus, the value of x is 40.

Answer:
The mode are: 7, 8
Step-by-step explanation:
Given

Required
Determine the mode
We start by arranging the given data in ascending order
The ordered data are:

From the above data.
7 has a frequency of 4
8 has a frequency of 4
10 has a frequency of 1
11 has a frequency of 2
The data with the highest frequency is the mode.
We can see that 7 and 8 both have frequencies of 4
<em>Hence, the mode are: 7, 8</em>
