Answer:
Step-by-step explanation:
If AB is a tangent of a circle, then the angle B is right angle. Therefore the triangle ABC is a rigth triangle.
BC and x are the radius of a circle. Therefore BC = x.
Use the Pythagorean theorem:
We have
Substitute:
<em>subtract 6400 from both sides</em>
Ok, so first this is a system. You have:
8x+12y=3200
And
X+y=300.
That means y= -X + 300.
If you replace "y" in the first equation with -X+300, it would be 8x+12(-X+300)=3200.
If you simplify that, X will be equal to 100. Now go back to the second equation, which is X+y= 300.
Now that you know X is 100, you can subtract it from 300 to find y.
So,
X=100 and y=200!
Hope this helps!!!

Answer:
$10.12
Step-by-step explanation:
Step one:
given data
we are told that the cost of binoculars is $155.75
and also the sales tax is 7%
Step two:
We want to first solve for the sales tax which is 7% of $155.75
=7/100* 155.75
=0.070*155.75
=10.12
Cassie will pay a tax of $10.12
Also Cassie will pay a total amount of
= 155.75+10.12
=$165.87
The answer is 65. That's the nearest whole number.
