To find a missing side of a right triangle use the Pythagorean theorem
A2+b2=c2
C is the hypotenuse (long side)
Plug into the equation
11^2+b2=12^2
121+b2=144
So subtract 144-121 to get the missing side you get 23
Take the square root
It will be 4.7
If they want it rounded
X=5
If I had any mistakes in my answer I am sorry but everything should be correct

What is the area of this composite figure?

Natalija [7]

Answer:

C.) 7.14 in²

Step-by-step explanation:

The figure is made up of a square and a circle. The circle is divided in half and each piece is set on one side of the square. This means that the diameter of the circle is equal to the length of the sides of the square, 2 inches.

The area of the square can be found by multiplying length times the width:

$2*2=4$

The area of the square is 4 inches, and since we multiplied two lengths, we square the value:

A=4in²

Now find the area of the circle using the formula:

$A=\pi r^2$

The radius is half of the diameter, so the radius is 1. Insert values and solve:

$A=\pi *1^2\\\\A=\pi *1\\\\A=\pi$

The area of the circle is equal to π. Add the values together:

$4+\pi =7.14$

The area of the figure is 7.14 in²

The price of a bottle of shampoo was marked up 15%, then marked down 4%. If the original price was $4.50, what is the new price?

balandron [24]

Answer:

Cost of shampoo = $4.50

% Mark up of Shampoo = 15%

15% Mark up of Shampoo = 15/100 x $4.50 = $0.67

Price of Shampoo 15% Mark up = $4.50 + $0.67 = $5.17

% Mark down of Shampoo = 4%

4% Mark down of shampoo = 4/100 x $5.17 = $0.21

Price of Shampoo 4% Mark down = $5.17 - $0.21 = $4.96
