IRINA_888 [86]

Answer:

a = 12

b = 2

c = 11

Step-by-step explanation:

$\frac{( {x}^{5}y {z}^{4} )^{3} }{ {x}^{3} yz} = {x}^{a} {y}^{b} {z}^{c} \\ \\ \frac{ {x}^{5 \times 3}y^{3} {z}^{4 \times 3} }{ {x}^{3} yz} = {x}^{a} {y}^{b} {z}^{c} \\ \\ \frac{ {x}^{15}y^{3} {z}^{12} }{ {x}^{3} yz} = {x}^{a} {y}^{b} {z}^{c} \\ \\ {x}^{15 - 3} {y}^{3 - 1} {z}^{12 - 1} = {x}^{a} {y}^{b} {z}^{c} \\ \\ {x}^{12} {y}^{2} {z}^{11} = {x}^{a} {y}^{b} {z}^{c} \\ \\ equating \: like \: terms \: from \: both \: sides \\ \\ {x}^{12} = {x}^{a} \: \implies \: a = \boxed{ 12}\\ \\ {y}^{2} = {y}^{b} \: \implies \: b = \boxed{ 2} \\ \\ {z}^{11} = {z}^{c} \: \implies \: c = \boxed{ 11}$

Compare the average score of a student at the beginning of a month and at the end of that month, if at first, it increased by 40

IceJOKER [234]

Answer:

Increased by 5%

Step-by-step explanation:

Let at the beginning the student's score be $s$ points.

At first, it increased by 40%. So, the new score is

$s+0.4s=1.4s$

Then it decreased by 25%, so the new score is

$1/4s-0.25\cdot 1.4s=1.4s-0.35s=1.05s$

At the beginning of a month the score was $s$ and at the end of that month the score was $1.05s$ . Since $1.05>1,$ the score increased by $1.05-1=0.05=5\%$
