Explain the different ways it is possible to add two rational numbers and get a negative number

snow_lady [41]

<u><em>Answer:</em></u>
both numbers are negative
negative number is greater than the positive number

<u><em>Explanation:</em></u>
<u>In order to add two rational numbers and get a negative value, one of two scenarios should occur:</u>
<u>1- both numbers are negative.</u>
In this case, the answer would definitely be negative as the two numbers are originally negative
<u>Examples:</u>
-9 + -2 = -9 - 2 = -11
$\frac{-1}{2} + \frac{-3}{2} = \frac{-4}{2} = -2$

<u>2- negative number is greater than the positive number</u>
In this case, the negative sign would dominate and the result would be negative
<u>Examples:</u>
-9 + 3 = -6
$\frac{-5}{6} + \frac{2}{6} = \frac{-3}{6}$

Hope this helps :)

Answer: V≈900 ft³

Step-by-step explanation:

Formula

V=πr²h

Given

r=5 ft

h=12 ft

Solve

V=πr²h

V=π(5)²(12)

V=π(25)(12)

V=300π

V≈300(3)

V≈900 ft³

Hope this helps!! :)

WILL REWARD THE BRAINLIEST

Gnom [1K]

Answers and Step-by-step explanations:

9-18.

a) All the angles of a triangle add up to 180, by definition. So, we can write the expression: 30 + 115 + x = 180.

Then, we can just solve for x by subtracting 30 and 115 from both sides:

x = 180 - 115 - 30 = 35 degrees

b) Again all three angles should add up to 180, so:

x + x + x = 180 ⇒ 3x = 180 ⇒ x = 180/3 = 60 degrees

9-19.

a) These angles add up to 180:

2x + x + 30 = 180 ⇒ 3x + 30 = 180 ⇒ 3x = 150 ⇒ x = 50

2x = 50 * 2 = 100

The missing angles are 100 degrees and 50 degrees.

b) Again, these add up to 180:

x + 10 + x + 90 = 180 ⇒ 2x + 100 = 180 ⇒ 2x = 80 ⇒ x = 40

x + 10 = 40 + 10 = 50

The missing angles are 50 degrees and 40 degrees.

Hope this helps!

What is the sum of the counting numbers 1 - 40

AVprozaik [17]

Simply it as follows:

1 + 39 = 40
2 + 38 = 40 etc

18 + 22 = 40
19 + 21 = 40

There are 19 of these plus 40 itself . . .therefore 20 of them

20 x 40 = 800

And finally the last number not used, 20

Therefore 800 + 20 = 820
