Answer:

1-------------- Commutative property of addition

You can commute the terms in a addition, so doesn't matter wat therm goes left or right,

2 ------------ is multiplicative inverse

Each number X has another number Y so X*Y=1

3-------------- Associative property of addition

When you have parentheses in this type of addition, the order in what you do te equation doesn't matter

4 ------------- distributive property

You can distribute the multiplication here, so x(a +b) = x*a + x*b

5 ------------ Additive identity

There exist one number a so for every number x, x+a = x, and the number a is te zero.

What is the l and w of a rectangular field of 40 ft perimeter?
shusha [124]
The perimeter doesn't tell you the dimensions.

With a 40-ft perimeter, there an infinite number of possibilities
for the length and with.  The only thing we know for sure is that
the sum of (length + width) is 20-ft.

The field could be . . .

1'  by  40'
2'  by  20'
3'  by  13-1/3 '
4'  by  10'
5'  by  8'

Mrs. Lavetan has 45 to complete her writing paper. She spend 10 and 1/8 min to planning her paper and 15 and 1/2 minutes weighti
Flura [38]

Answer: 20 minutes

Step-by-step explanation:

She has 45 mins to complete her writing paper.

She spends: 10\frac{1}{8} minutes to plan her paper.

She spends: 15\frac{1}{2} minutes writing rough drafts.

How much time left does she have?

45-(10\frac{1}{8} +15\frac{1}{2})

45-(10+15(\frac{1}{8}+\frac{1}{2}))

45-(25\frac{(1)(2)+(8)(1)}{(8)(2)})

45-(25\frac{2+8}{16} )

45-(25\frac{10}{16}) Simplify the fraction.

45-(25\frac{5}{8})

45-25(\frac{5}{8})

So she has approximately,

20\frac{5}{8} =\frac{165}{8}= 20 minutes.

The Toblerone company packages chocolate candy in a container that is a triangular prism. The base is an
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
