Answer:
My answer is 57.776
Step-by-step explanation:
Diameter= 9.2 km
3.14×2 = 6.28
6.28× 9.2
= 57.776
Dunno about rounding it to tenths cause that would be 60
its A because 3 plus 6 is 9 and they're both negitive. you then leave the 3x^2 and leave the x/2 both still posivive
Answer:
|x|<1.5
if x=0
0<1.5 is true
if x=1.5
1.5<1.5
true
if x=-1.5
|-1.5|<1.5
anything greater than 1.5 or less than -1.5 doesn't work
the way to solve is
assume that the inside is negative so if you had
|x|=a then to solve
x=a
x=-a
Answer:
x = -1
General Formulas and Concepts:
<u>Pre-Alg</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
5x - (x + 4) + 1 = 3 - 2(x + 6)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute: 5x - x - 4 + 1 = 3 - 2x - 12
- Combine like terms: 4x - 3 = -2x - 9
- Add 2x on both sides: 6x - 3 = -9
- Add 3 to both sides: 6x = -6
- Divide both sides by 6: x = -1
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: 5(-1) - (-1 + 4) + 1 = 3 - 2(-1 + 6)
- Parenthesis (Add): 5(-1) - 3 + 1 = 3 - 2(5)
- Multiply: -5 - 3 + 1 = 3 - 10
- Subtract: -8 + 1 = -7
- Add: -7 = -7
Answer:
the volume of the cube will be 44 cm³ or D (nearest whole number)
Step-by-step explanation:
A cube has equal size of edges. Since it has a face diagonal of 5cm then using Pythagoras theorem s²+ s²= 5², where s is the side of the cube.
Therefore, 2s²=25
s²= 12.5
s = √12.5 = 3.536 cm
The volume of a cube is s³ (s×s×s) = 3.536³= 44.212 cm³,
