Answer:

1450 cm

Step-by-step explanation:

A cardboard box is shaped like a rectangular prism.

To solve the above question, we apply the formula for Surface Area of a Rectangular Prism

A=2(wl+hl+hw)

Where

w = width = 5cm

I = length = 25cm

h = height = 20 cm

=2 × (5×25+20×25+20×5)

= 2(125 + 500 + 100)

= 2(725)

=1450 cm of cardboard material should be used.

Answer:

71

Step-by-step explanation:

Add 46 to each number, see if the sum is in the list. In the set of 7 numbers listed, two of them are even (24 and 38), and the other 5 numbers are odd

71

We do not need to look at all differences.

We need to find two numbers fairly far appart,

and not all look promising.

You could look at approximate differences,

or you could look at the last digit.

71-35 and 63-17 are the only promising differences,

because 71 and 63 are the only numbers large enough to be 46 more than another number in that list,

and when you calculate the last digit you calculate

11-5=6 and 13-7=6.

71-35=36

Question:

Make a list of the different arrangements that Mrs. Buchanan could use.

Answer:

[tex](x,y) = \{(1,36),(2,18),(3,12),(4,9),(6,6)\}[/tex]

Step-by-step explanation:

Given

[tex]Members = 36[/tex]

[tex]Rows\ Limit = 6[/tex]

Represent the rows with x and the column, y.

This means that:

[tex]x * y = 36[/tex]

Make y the subject:

[tex]y = \frac{36}{x}[/tex]

The list is then generated as follows:

When x = 6.

[tex]y = \frac{36}{6} = 6[/tex]

[tex](x,y) = (6,6)[/tex]

When x = 5

[tex]y = \frac{36}{5} = 7.2[/tex]

This result can not be use because the result of the number of columns must be an integer

When x = 4

[tex]y = \frac{36}{4} = 9[/tex]

[tex](x,y) = (4,9)[/tex]

When x = 3

[tex]y = \frac{36}{3} = 12[/tex]

[tex](x,y) = (3,12)[/tex]

When x = 2

[tex]y = \frac{36}{2} = 18[/tex]

[tex](x,y) = (2,18)[/tex]

When x = 1

[tex]y = \frac{36}{1} = 36[/tex]

[tex](x,y) =(1,36)[/tex]

So, the possible list is:

[tex](x,y) = \{(1,36),(2,18),(3,12),(4,9),(6,6)\}[/tex]

Answer:

The answer is below

Step-by-step explanation:

a) Let y represent the amount of time kiran slept, hence:

y = x - (1/10)x = x - 0.1x

y = 0.9x

b) Let y represent the amount of time Mia practice, hence:

y = x - (2/5)x = x - 0.4x

y = 0.6x

c) Let y represent the amount of drink kiran drank, hence:

y = x + (4/3)x = 7x / 3

y = 7x/3

d) Let y represent the money Mai spent, hence:

y = x - (1/4)x  = x - 0.25x

y = 0.75x

e) Let y represent the amount of almond kiran ate, hence:

y = x + 1.5x = 2.5x

f) Let y represent the recycling Mai collected, hence:

y = x - (3/10)x = x - 0.3x

y = 0.7x

g) Let y represent the amount of km kiran walked, hence:

y = x + (3/8)x

y = (11/8)x

h) Let y represent the amount of puzzles mai completed, hence:

y = x + (3/5)x = x + 0.6x

y = 1.6x

Step-by-step explanation:

Answer:

base = 519.62, height = 173.21 m

Step-by-step explanation:

Let the base and height of the triangle be represented by b and h respectively.

Thus,

b = 3h

Area of a triangle = [tex]\frac{1}{2}[/tex] x base x height

For the given triangle,

area = [tex]\frac{1}{2}[/tex] x b x 3h

       = [tex]\frac{3}{2}[/tex]bh

Area of the triangle = [tex]\frac{3}{2}[/tex]bh

To determine the number of hectares,

36 per hectare = 486

hectare = [tex]\frac{486}{36}[/tex]

             = 13.5

numbers of hectares = 13.5

Area of the hectares = number of hectares x 10 000 m²

                                   = 13.5 x 10 000

                                  = 135000

Total area of the hectares = 135 000 m²

So that,

area of the hectares = area of the triangle

area of the triangle = [tex]\frac{3}{2}[/tex]bh

135 000 = [tex]\frac{3}{2}[/tex]bh

270000 = 3bh

bh = [tex]\frac{270000}{3}[/tex]

     = 90000

bh = 90000

But, b = 3h

3h x h = 90000

3[tex]h^{2}[/tex] = 90000

[tex]h^{2}[/tex]  = [tex]\frac{90000}{3}[/tex]

     = 30000

h = [tex]\sqrt{30000}[/tex]

  = 173.2051

h = 173.21 m

So that,

b = 3 x 173.2051

  = 519.6153

b = 519.62

Therefore, the base of the triangle is 519.62 m, while the height is 173.21 m.

The answer is 10.5, but don't put 10.5 if it's just asking for the number and not the unit only put (10)!!!
