Question:

Which of the following expressions represents the distance between 1.7 and −1/2 on a number line?

Choose 1 answer: 

A.\ |1.7 - 1/2|

B.\ |1.7 -(-1/2)|

C. None of the above

Answer:

B.\ |1.7 -(-1/2)|

Step-by-step explanation:

Given

Numbers: 1.7 and -1/2

Required

Determine the distance

To calculate the distance, we start by calculating the difference between the given numbers;

Difference = 1.7 - (-1/2)

Then, we calculate the distance;

<em>In this case, the distance is meant to be positive; So, we'll introduce the symbol for absolute value;</em>

Hence,

Distance = |Difference|

Substitute 1.7 - (-1/2) for Difference;

Distance = |1.7 - (-1/2)|

<em>Hence, the correct option is B</em>

dolphi86 [110]

Answer:

76017.69 mm²

631000 mm³

295045.04 mm³

Step-by-step explanation:

Surface area = bh + 2ls + lb

Since the sides of the triangular prism are equal (equilateral triangle) = 60 mm each

Height = 405 mm

The surface area of triangular = 76017.69 mm

The volume of triangular prism :

1/2 * base * height * length

Volume = 631000 mm³

If amount of chocolate inside = 335954.96 mm3

Empty space =

Volume of triangular prism - amount of chocolate inside

631000 - 335954.96

= 295045.04 mm³

saveliy_v [14]

Answer:

9 {x}^{2}  - 49

Step-by-step explanation:

Do FOIL, first outside inside last

3x × 3x = 9x^2

3x × -7 = -21x

7 × 3x = 21x

7 × -7 = -49

9 {x}^{2}   - 21x + 21x - 49 \: midde \: cancels \: each \: other \: out

So it would just be 9x^2 - 49
