What is the total cost of a $150.00 necklace if the sales tax is 6.5%

LiRa [457]

The best thing to do is to find what 1% is, and you can do this by dividing 150 by 100.
150/100= 1.5
As you're looking for 6.5%, you've got to multiply 1.5 by 6.5
1.5*6.5= 9.75
You've then got to add 9.75 and 150 together
150+9.75= $159.75
Therefore, after the sales tax, the cost of the necklace is $159.75
Hope this helps :)

An altitude of a right triangle to its hypotenuse divides this hypotenuse into two segments that measure 9cm, and 16cm. What are

ozzi

Answer:

Step-by-step explanation:

Let a be the length of the altitude, then from the given triangles, applying the basic proportionality theorem, we get

$\frac{BD}{AD}=\frac{DC}{BD}$

⇒ $(BD)^{2}=DC{\times}AD$

⇒ $(BD)^2=9{\times}16$

⇒ $BD=\sqrt{144}$

⇒ $BD=12 cm$

Thus, the length of altitude is: 12 cm.

Now, $\frac{AB}{AD}=\frac{AC}{AB}$

⇒ $(AB)^{2}=220$

⇒ $AB= 14.83 cm$

Also, $\frac{BC}{DC}\frac{AC}{BC}$

⇒ $(BC)^{2}=400$

⇒ $BC=20 cm$

Thus, the lengths of the legs of this triangle are 14.83 and 20 cm.

Please show your work !!!!!!!!!!!!

dedylja [7]

Answer:

$(3.4)$

Step-by-step explanation:

Our equation is $f(x)=-2(x-3)^2+4$
Now there are 2 ways you can do this, I'll show you the shortcut
If you have an equation like this, just take the value in parenthesis and equate it to zero
$x-3=0.x=3$ is the x of the vertex
Put this back into the equation
$f(x)=-2(x-3)^2+4\\x=3\\f(3)=-2(3-3)^2+4\\f(3)=-2(0)^2+4=4$ this is the y

When you find the surface area of a cube, you ________ the length of the cube and<br> multiply by 6

Papessa [141]

Answer:

The word for the blank would be "square".

Step-by-step explanation:

Since the area of a face of a cube would be square its side length, the total surface area of a cube would be that times 6.

Hope this helped!
