Fantasty-N-Fun sells gaming cards for $9.99 but they pay only $6.75 per card. What is the percent markup
Sliva [168]
100%=9.99
×%=6.75

9.99x=100×6.75
9.99X=675

X=675/9.99
67.567% or 67.57

you could also say:

6.75/9.99=0.67567

0.67567×100=67.57%

so the markup is 100%-67.57%=32.43%

EXPLAIN THE SECOND PART.......
alexdok [17]
\tan^2\theta-\sin^2\theta=\dfrac{\sin^2\theta}{\cos^2\theta}-\sin^2\theta
=\sin^2\theta\left(\dfrac1{\cos^2\theta}-1\right)
=\sin^2\theta(\sec^2\theta-1)
=\sin^2\theta\tan^2\theta

Now if 0^\circ, then both \sin\theta>0 and \tan\theta>0. Adding two positive numbers gives another positive number, so \tan\theta+\sin\theta>0. Why this is useful will be apparent shortly.

Back to the identity:

\tan^2\theta-\sin^2\theta=\tan^2\theta\sin^2\theta

Factorizing the left hand side, we have

(\tan\theta-\sin\theta)(\tan\theta+\sin\theta)=\tan^2\theta\sin^2\theta

Now, any number squared will be positive, which means the right hand side is necessarily greater than 0.

We showed earlier that \tan\theta+\sin\theta>0. So we understand that we have

\underbrace{(\tan\theta-\sin\theta)}_?\underbrace{(\tan\theta+\sin\theta)}_+=\underbrace{\tan^2\theta\sin^2\theta}_+

The only way to multiply a number by a positive number to get yet another positive number is to have the first number also be positive, which means

\tan\theta-\sin\theta>0

and from this it follows that

\tan\theta>\sin\theta

in the provided region.

Please help me 16% of what is 41?
saul85 [17]

The answer is 256.25


EXPLANATION


Let x represent the number.



Then, \frac{16}{100}x=41



We cross multiply yo obtain,



16x=41\times 100



We now divide both sides by 16.



x=\frac{4100}{16}



This will give us,


x=256.25




Therefore the number is 256.26

Score: 0 of 1 pt
jonny [76]

Answer:

See attachment for graph

Step-by-step explanation:

Given

y = x^2 - 3

Required

The graph of the equation

First, we determine the range of y

x = -3

y = x^2 - 3 \to y = (-3)^2 - 3 = 6

(-3,6)

x = -2

y = (-2)^2 - 3 = 1

(-2,1)

x = -1

y = (-1)^2 - 3 = -2

(-1,-2)

x=0

y = 0^2 - 3 = -3

(0,-3)

x = 1

y= 1^2 - 3 = -2

(1,-2)

x = 2

y =2^2 - 3 = 1

(2,1)

x = 3

y = 3^2 - 3 = 6

(3,6)
