Here's the key:
Any radius that's perpendicular to a chord, bisects the chord.
So the piece of a radius that's perpendicular to the chord bisects it,
and the part of the chord that forms a side of the triangle is also 6.5 .
The triangle is a right triangle, and its hypotenuse is a radius of the circle.
the diameter of the circle is 16, so the length of the radius is 8 .
So now you know the length of the hypotenuse and one leg of a right
triangle, and side 'x' is the other leg.
This is where Pythagoras comes in.
(hypotenuse)² = (one leg)² + (the other leg)²
(8)² = (6.5)² + x²
64 = 42.25 + x²
x² = 64 - 42.25
x² = √21.75
x = about 4.664... (looks like choice-A)
20 watches are made according to the cost of 385 dollars
Answer:
16,575
Step-by-step explanation:
3.5% of 15,000 is 525$
525 x 3 = 1575$
15,000 + 1575 = 16,575
For the answer to the question above asking <span>What is the factorization of g3 – 125?
</span>The first term is, g2 its coefficient is 1.
The middle term is, +5g its coefficient is <span> 5 </span>.
The last term, "the constant", is <span> +25
</span>
Multiply the coefficient of the first term by the constant 1 • 25 = 25<span>
</span>Find two factors of 25 whose sum equals the coefficient of the middle term, which is 5.<span> Since there are no factors.
The answer will be,
</span>
<span>(g - 5) • (g2 + 5g + 25)</span>
It asks for area. area for rectangle is length * width. and triangle is 1/2 * base * height
The long side area has sides of 10 and 6. So area for that side is:
10 * 6 = 60
(I got the 6 from using the height of other side. they are same height)
area of other side is the area of rectangle and triangle added together.
area rectangle = 8 * 6 = 48
area triangle = 1/2 * 3 * 8 = 12
area side = 12 + 48 = 60
area 2 sides = 60 + 60 = 120
