Customers who purchase museum tickets in advance receive 10% off the regular admission price. Anias paid a sale price of $54. He

alisha [4.7K]

Answer:

Regular price of a ticket = $60

Step-by-step explanation:

Given:

On purchasing museum tickets in advance customers get 10% off on the regular price of ticket.

Anias paid the sale price of ticket = $54

To find the regular price of ticket.

Solution:

Let the regular price of ticket in dollars be $=x$

Discount offered for booking in advance = 10%

Discount amount in dollars = $Discount\ percent \times Regular\ price=10% \times x =0.10 \times x =0.1x$

Sale price of a ticket in dollars= Regular price - Discount amount= $x-0.1x=0.9x$

Sale price given for a ticket = $54

So, we have:

$0.9x=54$

Dividing both sides by 0.9

$\frac{0.9x}{0.9}=\frac{54}{0.9}$

∴ $x=60$

∴ Regular price of a ticket = $60

20 POINTS <br> Can someone please explain what I did wrong?

mr_godi [17]

Your diagram is correct.

I would have however written the Given as stated

Given :

XB≅XA≅AY≅YB ( If they are equidistant then they are all the same distance, thus the values will all be equal)

Prove:

<x≅<b≅<y≅<a (this is because a square is formed) < is angle

XM≅YM≅AM≅MB (The fact that the previous statements are true means that this is a square, if M is the midpoint than all these segments are equal)

MX≅MY

Im not sure what you did wrong besides maybe you didn't prove it well enough, everything is correct that you have written. I cant read the pen but it looks like you were missing a step.

Solve negative one fifth times the quantity 4 minus 14 times the quantity one fourth squared end quantity end quantity.

asambeis [7]

The value of the expression is one eight

<h3>How to solve the expression?</h3>

The expression is given as:

negative one fifth times the quantity 4 minus 14 times the quantity one fourth squared end quantity

Rewrite properly as:

-1/5 * (4 - 14) * (1/4)^2

Evaluate the difference

-1/5 * (-10) * (1/4)^2

Evaluate the exponent

-1/5 * (-10) * 1/16

This gives

2 * 1/16

Further, evaluate

1/8

Hence, the value of the expression is one eight
