Then square both sides

X+3=1

Then subtract 3

X=-2

Hope this helps!

Suppose that you are a manager of a clothing store and have just purchased 100 shirts for $15 each. After a month of selling the shirts at the regular price, you plan to have a sale giving 30% of the original selling price. However ,you want to make a profit of $6 on each shirt at the sale price. What should you price the shirts at initially to ensure this?

Answers

He should set the original price at $27.30

When you say "Plan to have a sale giving 30% of the original selling price", I suppose it's taking away 30%? So taking away 30% is like $15 - $4.5 = $10.50
Adding $6 more is $16.50.
If you're saying the manager is selling the price 30% of $15 then the price is $4.50 Plus the $6, it should be $10.50

So the answer should either be $16.50 or $10.50

To the nearest tenth, what is the length of the hypotenuse of an isosceles right triangle with a leg of 7 3 inches? A) 15.7inches
B) 16.2 inches
C) 17.1 inches
D) 18.5 inches

Answers

Answer:

the answer is the option C

$17.1\ in$

Step-by-step explanation:

we know that

An isosceles right triangle has two equal legs

Let

x------> the length side of the hypotenuse

y-----> the length side of the leg

Applying the Pythagoras theorem

$x^(2) =y^(2)+y^(2)$

$x^(2) =2y^(2)$

In this problem we have

$y=7√(3)\ in$

Substitute and solve for x

$x^(2) =2(7√(3))^(2)$

$x=17.1\ in$

Whitch simplified fraction is equal to 0.53

Answers

The decimal .53 has the 3 in the hundredths place, so the fraction that this was originally is $(53)/(100)$ . When you divide 53 by 100 on your calculator, you will get backk .53

The most simple version of 0.53 in a fraction would be 53/100.

Since 53 is a prime number, we divide it between 100, and we get $(53)/(100)$
