Answer:
1000ml
Step-by-step explanation:
4 days she drank ½ of the bottle
so she drank ⅛ l of juice everyday
so
1000ml is the answer
Answer:
16.5mm to. 1 decimal place
Step-by-step explanation:
Please check attachment for diagrammatic representation of the triangle.
Since one of the angles of the triangle is 90, this means that we are dealing with a right angled triangle
To find the length of AC, we make use of pythagoras’ theorem which states that the square of the hypotenuse equals the sum of the square of the other two sides. The hypotenuse is the longest side of the triangle which we have as 17.88 mm
Mathematically therefore
17.8^2 = 6.6^2 + AC^2
AC^2 = 17.8^2 - 6.6^2
AC^2 = 283.28
AC = √(273.28)
AC = 16.53 mm
This is 16.5 to 1 decimal place
Answer:
they are not parallel
Step-by-step explanation:
Given the equations -3x – 3y = 1 and -3x – 4y = 5
Get the slope of each line
REwrite in the form y = mx+c
For the line -3x-3y = 1
-3y = 3x + 1
y = 3x/-3 + 1/-3
y = -x - 1/3
Slope m = -1
For the line -3x - 4y = 5
-4y = 3x + 5
y = -3/4 x - 5/4
Slope of the line is -3/4
Hence since both lines have different slopes, they are not parallel
ANSWER:
17
EXPLANATION:
1st: to find the mean you add all the numbers
2nd: divide by how many numbers there are
So basically 18+15+20+15 then divide by 4 because there are 4 numbers and once you do that it is 17
Hope this helps!!!
Answer:
We conclude that the constant of proportionality between the number of shirts and how much they cost is:
k = 8
Hence, option 'D' is correct.
Step-by-step explanation:
We know that when 'y' varies directly with 'x', we get
y ∝ x
y = kx
k = y/x
where k is called the constant of proportionality
Given the points
For (10, 80)
substituting y = 80 and x = 10 in the equation
k = y/x
k = 80/10 = 8
For (20, 160)
k = y/x
k = 160/20 = 8
For (50, 400)
k = y/x
k = 400/50 = 8
It is clear that the value of k is the same for all the points.
Thus, the value of k = 8
Therefore, we conclude that the constant of proportionality between the number of shirts and how much they cost is:
k = 8
Hence, option 'D' is correct.
