If A(x', y') & B(x",y") the the distance AB is given by the following formula:

AB =√[(x"-x')² + (y"-y')²]

Plug into the above with A(4,5) and B(-4,11).

AB =√[(-4-4)²+(11-5)²] =√(-8)²+(6)² = √(64) + (36) =√100 = 10

AB =√[(x"-x')² + (y"-y')²]

Plug into the above with A(4,5) and B(-4,11).

AB =√[(-4-4)²+(11-5)²] =√(-8)²+(6)² = √(64) + (36) =√100 = 10

**The length of the longest metal rod that can be sent is 12 inches.**

As given, the only boxes available for shipping are 7-inch cubes. As Jorge needs to ship a thin metal rod to a metalworking shop, he will put the rods diagonally or space diagonally in the box.

The space diagonal of a cube can be found by the formula :

=

Here, x is 7 inches.

So, Diagonal is =

= inches.

Rounding this to nearest whole number we get 12.

**So, the length of the longest metal rod that can be sent is 12 inches.**

QUESTION POSTED AT 28/03/2020 - 12:44 PM

Space in the box = volume

volume = length x width x height

box 1 volume = 15 x 20 x 10 = 3000

box 2 volume = 15 x 20 x 14 = 4200

how much space is left = box 2 - box 1 = 1200 inches

volume = length x width x height

box 1 volume = 15 x 20 x 10 = 3000

box 2 volume = 15 x 20 x 14 = 4200

how much space is left = box 2 - box 1 = 1200 inches

QUESTION POSTED AT 28/03/2020 - 12:42 PM

**Answer:**

Option A. 6.25

**Step-by-step explanation:**

The data shows the number of grams of fat found in different health bars is

11, 11.5, 10.5, 17, 14.5, 14.5, 18, 17, 19

Now we will arrange the data in ascending order

10.5, 11, 11.5, 14.5,** 14.5**, 17, 17, 18, 19

Middle of the numbers is 14.5 which is median of the data.

We know IQR = Median of first quartile - median of second quartile

Median of first quartile =

And median of second quartile =

Now IQR = 17.5 - 11.25 = 6.25

Therefore **Option A 6.25** is the correct option.

Since we are given 2 sides and 2 angles, we can use the Side Angle Side (SAS) method. The area of a triangle is given by the formula:

Area = absinC/2; where a and b are adjacent sides and C is the angle between a and b.

Area = 5*8*sin31°/2 = 10.3 square units.
