Which expression is equivalent to 4^-5?
Basile [38]
Since there is a negative exponent, you need to first convert that into a positive exponent which is going to be 1/4^5
Then, we can find out the answer by simply breaking apart the exponents into 5 groups of 4.
1/(4)(4)(4)(4)(4)

A jeweler who buys a ring from a jewelry maker for $125 marked with the price by 135% for sale in the store what is the selling
siniylev [52]
Marked up by 135% means
new price=original price+(original price times markup) =125+(125 times 1.35)=293.75
tax
293.75 times 0.075=22.03125

293.75-22.03125=271.718 so aprox $271.72


selling price would be $271.72

HELP FAST GIVE A DECENT AMOUNT OF POINTS! FOR EASY!
laila [671]

Answer:

The value of angle is 56.9°

Step-by-step explanation:

First, you have to find the length of hypotenuse using Pythagoras' Theorem, c² = a² + b² :

{c}^{2}  =  {a}^{2}  +  {b}^{2}

let \: a = 8.25 \\ let \: b = 6.45

{c}^{2}  =  {8.25}^{2}  +  {6.45}^{2}

{c}^{2}  = 68.0625 + 41.6025

{c}^{2}  = 109.665

c =  \sqrt{109.665}

c = 10.47cm \: (4s.f)

In order to find θ, you have to apply Sine Rule :

\sin(θ)  =  \frac{opposite}{adjacent}

let \: oppo. = 8.77 \\ let \: hypo. = 10.47

\sin(θ)  =  \frac{8.77}{10.47}

θ =  { \sin( \frac{8.77}{10.47} ) }^{ - 1}

θ = 56.9 \: (1d.p)

[ please help! ] The graph below shows a line segment PQ.
Tpy6a [65]

Answer:

Slope of the line segment PQ is 1/2.

Step-by-step explanation:

We are given with a line connecting two points P and Q.

The coordinates of P are (4,4) and the coordinates of Q are (-2,1).

Slope of line joining two points (x_{1},y_{1}) and (x_{2},y_{2})

is given by the formula \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Hence the slope of the line PQ is \frac{1-4}{-2-4}=\frac{-3}{-6}= \frac{1}{2}

Therefore correct option is 'C' that is 1/2.
