Answer:
133 pieces of 15cm can be cut from the ribbon.
Step-by-Step Explanation:
Length of ribbon = 20 meters
Length needed to be cut = 15 cm
We will convert meters into centimeters.
1 meter = 100 cm
20 meters = 2000 cm
Number of pieces =
Number of pieces = 133.33
Rounding off to nearest whole number = 133
Hence,

The solutions of the equation are;
Given the function:
To find the zero of this function.
Set f(x) = 0
⇒
On comparing this with equation [1] we have;
a = 6, b = 12 and c = -7
then;
or
or
Therefore, the zeros of the quadratic function f(x) are;
and
Answer:
17mL
Step-by-step explanation:
Convert 0.85 gr to miligrams
If 100 mg is 1 gr. Then, 0.85 gr is 850 mg
So, 850 multiply for 5ml and divide for 250 ml
or
So all mg is gone and the amount of mililiters is 17
