To answer this question, we need to know first the unit conversion of each item in the choices such conversions are enumerated below:
1 centigram = 0.001 dekagrams
1 hectograms = 0.1 kilograms
1 grams = 1000 milligrams
1 dekagrams = 0.1 hectograms

From the choices, the correct unit conversion is the letter "B" which is "To find the number of hectograms in 4.5 kilograms, multiply 4.5 by 10". The solution is shown below:
4.5 kilograms * (1 hectograms / 0.1 kilograms), we need to cancel both kilograms such as the remaining unit is only the hectograms
4.5 * (1 hectograms / 0.1) where 1 divided by 0.1 is 10
4.5 * 10 hectograms

Therefore, 4.5kilograms should be multiplied by 10 in order to have hectograms as a unit.

Answer:

-4 and 5

Step-by-step explanation:

4*5 = x(x-1) ; cross multiply

20 = x²-x ; distribute multiplication over subtraction

x²-x-20 =0; subtract 20 from both sides

(x+4) (x-5) = 0; factor

x+4 =0 gives x = -4

x-5 =0 gives x = 5

30 ounces = how many pounds and ounces

Tatiana [17]

Answer: " 1 lb , 14 oz. " .

_________________________________________________

Step-by-step explanation:

_________________________________________________

Note the exact conversion: " 16 oz. = 1 lb. " .

→ {that is: " 16 ounces = 1 pound " .}.

_________________________________________________

30 oz. * ( 1 lb / 16 oz). = $\frac{30}{16}$ lbs. ;

= (30/2) / (16/2) lbs.

= (15 / 8) lbs. ;

_________________________________________________

8 ┌ 15

7 ;

______________________

The answer is equal to: " 1 7/8 lbs. " .

→ (1 lb) + (7/8) (lb). ;

______________________

→ (7/8) lb. = how many "oz." ??

_______________________

Note the exact conversion: " 1 lb. = 16 oz. " .

_______________________

→ $\frac{7 lb}{8}$ * $\frac{16 oz}{1 lb}$ ;

= $\frac{7}{8} * \frac{16}{1}$ oz. ;

→ The "8" cancels to a "1" ; and the "16" cancels to a "2" ;

→ {since: " {16 ÷ 8 = 2 } " ;

and: {since: " {8 ÷ 8 = 1 } " .

_______________________________________________

→ So we can rewrite as:

_______________________________________________

→ $\frac{7}{1} * \frac{2}{1}$ oz. ;

= { 7 * 2 } oz. ;

= 14 oz.

_______________________________________________

→ So:

_______________________________________________

→ " 30 oz. " = " (1 lb) + (7/8) lb. " ;

= " 1 lb. + 14 oz. " ;

= " 1 lb , 14 oz. " .

_______________________________________________

→ The answer is: " 1 lb , 14 oz. " .

_______________________________________________

Let us check our answer:

→ Does: " 1 lb. + 14 oz. = ? 30 oz. ? " ;

_______________________________________________

Note the exact conversion: " 1 lb. = 16 oz. " .

_______________________________________________

→ Does: " 16 oz. + 14 oz. = ? 30 oz. ?? " ;

_______________________________________________

₁

16 oz

<u>+ 14 oz </u>

30 oz.

_______________________________________________

→ Does: " 30 oz. = ? 30 oz. ? " ??? ; → Yes!
