What is Unit of Measurement?

A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.

We know that in an hour there are 60 minutes.

1 hour = 60 minutes

We need to subtract 3 hours, 50 minutes from 5 hours, 20 minutes.

In 3 hours 50 minutes we can calculate total number of minutes

3(60)+50

180+50=230

In 5 hours 20 minutes we can calculate total number of minutes

5(60)+20

300+20=320

Now subtract the minus 320 and 230

320-230

90 minutes

90 minutes means 1 hour 30 minutes

Hence, when we subtract 3 hours, 50 minutes from 5 hours, 20 minutes we get 1 hour, 30 minutes

Given points A(2, 3) and B(-2,5), explain how you could use the Distance Formula and an indirect argument to show that point C(O, 3) is NOT the midpoint of AB.

Answers

Answer:

Therefore C is not the midpoint of AB.

Step-by-step explanation:

Midpoint: The midpoint is a point from which the distance between the endpoints of a line segment is always equal.

Distance formula:

The distance between the points (x₁,y₁) and (x₂,y₂) is

$√((x_2-x_1)^2+(y_2-y_1))$

Given points are A(2,3) and B(-2,5).

If C(0,3) is the midpoint of the line segment AB,then AC=BC.

The distance between AC is

$√((0-2)^2+(3-3)^2)$

$=√(2^2)$

=2 units

The distance between AC is

$√((0-(-2))^2+(3-5)^2)$

$=√(2^2+2^2)$

$=4√(2)$ units.

Since AC ≠ BC

Therefore C is not the midpoint of AB.

Solve this problem: –282 – (+1,017) =

Answers

This question more or less tries to trick you with the positive number in parentheses, as you would carry out subtraction as normal. However, since the number you are subtracting from is also negative, it would be easier to think about it as adding two positives, and setting aside the negative symbol for the answer.

-282 - 1017 = -(282 + 1017) = -(1299) = -1299

which is your final answer.
-282 - (+1017) = -1299.
Hope that helped! =)

How can you use addition and subtract to put together and separate measures of an angle and its parts

How can you use addition and subtract to put together and separate measures of an angle and its parts

Adding and Subtracting angles can be put this way.
Complementary angles can be formed by two angles with total of 90 degrees.
Supplementary angles can be formed by two angles with total of 180 degrees.

X + Y = 90 degrees
Y = 90 - X
X = 90 - Y

X + Y = 180 degrees
Y = 180 - X
X = 180 - Y
