Answer:
1. Option D.
2. Option A.
Step-by-step explanation:
1. You need to follow these steps in order to estimate the sum of
:
Step 1: Add the digits in the ones places of the whole numbers (these are: 8, 9 and 5).
Step 2: Round the decimals to the nearest whole number:
Step 3: Add them together:
2. The procedure to estimate the difference of
is:

Rounded to the nearest whole number:

The slope is -4.7 because this equation is written in point slope form. This equation can be rewritten as y = -4.7x + 21. Point slope form is y = mx + b, with m being slope and b being y-intercept.
The answer is 210. You're welcome friend.
I’m not 100% true but i think it’s false, true, true :)
Answer:
<h2>49.49%</h2>
Step-by-step explanation:
volume of liquid in the flask= 200 cm^3
radius of the flask = 3 cm
height of the flask= 12 cm
volume of flask is given by =
putting values and solving we get =396 cm^3
therefore the volume unfilled= 396-200= 196cm^3
therefore % of volume unfilled= 196/396*100= 49.49%
