1kg is equal to 1000 grams:
To convert a value from kg to grams just add 3 zeros to the end.

(2x105)/(3x103) + 3x103 * 5x102

AleksAgata [21]

Answer:

1500066.66

Step-by-step explanation:

Given: $(2\times10^{5} )/(3\times 10^{3} ) + 3\times10^{3} \times 5\times10^{2}$

Now, simplifying it.

Using PEDMAS in solving the expression

First opening the parenthesis

= $2\times10^{5} /3\times 10^{3} + 3\times10^{3} \times 5\times10^{2}$

Next dividing the number

as per law of indices, $x^{m} \div x^{n} = x^{m-n}$

= $2\times10^{5-3} /3 + 3\times10^{3} \times 5\times10^{2}$

= $2\times10^{2} /3 + 3\times10^{3} \times 5\times10^{2}$

= $\frac{2\times10^{2} }{3} + 3\times10^{3} \times 5\times10^{2}$

Next multiplying the number as per PEDMAS

as per law of indices, $x^{m} \times x^{n} = x^{m+n}$

= $\frac{2\times10^{2} }{3} + 15\times10^{3+2}$

= $\frac{2\times10^{2} }{3} + 15\times10^{5}$

= $\frac{2\times 100}{3} + 15\times10^{5}$

Next dividing the number as per PEDMAS

= $2\times 33.33 + 15\times10^{5}$

Next multiplying the number as per PEDMAS

= $66.66+1500000$

Now adding the number

= 1500066.66

Answer:

19 dimes and 15 quarters.

Step-by-step explanation:

Lets substitute in the equation

565=10x+25(34-x)

565=10x+850-25x

15x=285

x=19

So...

34-19=15

The statemment 3+3=6 serves as a/an ___ to the conjecture that the sum of two odd numbers is an odd number.

s344n2d4d5 [400]

The statement 3+3=6 serves as a disproof to the conjecture that the sum of two odd numbers is an odd number.
Odd numbers are numbers which can NOT be divided evenly into groups of two.
6 can be divided by 2 (6:3=2), which means that the sum of two odd numbers is not an odd number.
On the other hand, there is a statement that is always true (a theorem) about the sum of two odd numbers: The sum of two consecutive odd numbers is divisible by 4.
