The mass of a bag of potatoes is 860 kg round to the nearest 10kg. i) Give the upper and lower bounds for the mass.
1 answer:
Answer:
- Lower bound ⇒ 855 kg
- Upper bound ⇒ 865 kg
Step-by-step explanation:
The upper bound is the highest number that a figure can be to be rounded off to the rounded figure.
The lower bound is the lowest number that a figure can be to be rounded odd to the rounded figure.
The lower bound of 860 to the nearest 10 is;
= 855 kg
855 is the lowest figure that can be rounded up to 860.
The Upper bound is;
= 865
865 is the highest figure because no figure above this can be rounded to 860.
<em>855 kg ≤ 860 kg < 865 kg</em>

Using the 30-60-90 triangle to find sine and cosine
sin(60 degrees) = 2√3 4.
sin(60 degrees) = √3 2.
sin(30 degrees) = 2 4.
sin(30 degrees) = 1 2.
cos(60 degrees) = 2 4.
cos(60 degrees) = 1 2.
cos(30 degrees) = 2√3 4.
cos(30 degrees) = √3 2.
