How do I get the answer

EleoNora [17]

$\bf sin^2(\theta)+cos^2(\theta)=1\implies cos^2(\theta)=1-sin^2(\theta)
\\\\\\
sec(\theta)=\cfrac{1}{cos(\theta)}\\\\
-------------------------------\\\\
\cfrac{1}{1+sin(\theta)}+\cfrac{1}{1-sin(\theta)}\impliedby LCD=[1-sin(\theta)][1+sin(\theta)]
\\\\\\
\cfrac{1\underline{-sin(\theta)}+1\underline{+sin(\theta)}}{[1-sin(\theta)][1+sin(\theta)]}\implies 
\cfrac{2}{[1-sin(\theta)][1+sin(\theta)]}\\\\
-------------------------------\\\\$

$\bf \textit{difference of squares}
\\ \quad \\
(a-b)(a+b) = a^2-b^2\qquad \qquad 
a^2-b^2 = (a-b)(a+b)\\\\
-------------------------------\\\\
\cfrac{2}{1^2-sin^2(\theta)}\implies \cfrac{2}{1-sin^2(\theta)}\implies \cfrac{2}{cos^2(\theta)}
\\\\\\
\cfrac{2}{1}\cdot \cfrac{1^2}{cos^2(\theta)}\implies 2sec^2(\theta)$

A bag of sweets contains mints and toffees only.There are 21 mints in the bag.One quarter of the sweets are toffees.Calculate th

Vedmedyk [2.9K]

Answer:

Total number of sweets in the bag is 28

Step-by-step explanation:

let the total number of sweets in the bag be x :

${ \tt{for \: toffees : }} \\ \frac{1}{4} \: of \: x$

therefore fraction of mints = 1 - fraction of toffees :

$= \frac{4}{4} - \frac{1}{4} \\ \\ = \frac{3}{4}$

therefore:

$= > \frac{3}{4} \: of \: x = 21 \: mints \\ \\ \frac{3}{4} \times x = 21 \\ 3x = 21 \times 4 \\ x = \frac{21 \times 4}{3} \\ x = 28$

total sweets number is 28
