Answer:

(i) 540kg

(ii) 5.56 (rounded off to 3 significant figures)

$108 \div 30 = 3.6kg$

$(i)3.6 \times 150 = 540kg$

$(ii)3.6 \times x = 20$

$x = \frac{20}{3.6}$

Answer:

The answer to your question is: 5 bottles

Step-by-step explanation:

Process

First week

Divide 24 by 8

24/8 = 3 bottles = 1/8

but Sanjay drank 3/8 = 9 bottles

And there are 24 - 9 bottles left = 15

- Second week

Divide 15 by 3

15/3 = 5 then 5 bottles = 1/3

but sanjay drank 2/3 = 10 bottles

Then, there are 15 - 10 bottles left = 5

If the statement if it cold then i wear a jacket is assumed to be true is it converse if i wear a jacket it must be cold also al

Archy [21]

The converse of any statement, true or false, is never always true. The only guaranteed true statement is a contrapositive of a true statement. A contrapositive is a statement where the hypothesis and conclusion are switched, and both sides are negated.
