Find each product or quotient. Express your answer in exponential form.<br> (-x^5y^7)/y^3
Alenkasestr [34]
Remember some laws
(ab)/c=a(b/c)
and
\frac{x^m}{x^n}=x^{m-n}
so

\frac{-x^5y^7}{y^3} =(-x^5)( \frac{y^7}{y^3})=(-x^5)(y^{7-3})=-x^5y^4

Half of the children in a library group like pets, one fourth don't like pets and seven children do not have any
erik [133]

Answer:

14 children

Step-by-step explanation:

Half the children like pets and a quarter of the children do not, so another quarter does not have preference. Let x = total number of children, and we would have this equation.

0.25x = 7

x = 28


Since we are asked to give the number of children who like pets, 28/2 = 14 is the answer.

An arc subtends a central angle measuring
barxatty [35]

Answer:

The arc is one-third of the circumference.

Step-by-step explanation:

The area of a circumference = 2πr

C = 2πr ... (1)

If an arc subtends a central angle measuring 2π/3 rad,

The length of the arc = rθ

Given θ = 2π/3

Length of the arc L = r(2π)/3

L = 2πr/3... (2)

L = 1/3(2πr)

Since C = 2πr

L = 1/3C

This shows that the arc is one-third of the circumference.
