nadya68 [22]

Answer:

Option (3)

Step-by-step explanation:

By applying the property of inscribed angle and intercepted arc in the given circle,

"Measure of an inscribed angle is half the measure of the intercepted arc"

$m(\angle LKJ)=\frac{1}{2}m(\text{arc LJ})$

$85=\frac{1}{2}(20x+10)$

$170=20x+10$

$20x=160$

$x=8$

Therefore, Option (3) is the correct option.

5/4y + 8 = 17.50 Please Help me

natima [27]

Step 1: Subtract 8 from both sides.
5/4y+ 8− 8= 17.5− 8
5/4y = 9.5

Step 2: Multiply both sides by 4/5.
(4/5) * (5/4y) = (4/5) * (9.5)

y = 38/5

I don't know how to factor this, what should I do to get the right answer

lina2011 [118]

Answer:

Step-by-step explanation:

First, you can reduce it

4(n^2-11n+30)

This should make it easier to work with. But remember, keep the 4 there. You cannot just get rid of it because it would change the value of the equation

Now find factors of 30 that have a difference or ad up to 11.

Factors of 30:

1, 30

2, 15

3, 10

5, 6

Ahh yes, 5 and 6 add to 11

4(n-5)(n-6)

A circle is placed in a square with a side length of 16 ft , as shown below. Find the area of the shaded region.

Luda [366]

Answer:

55.04 ft²

Step-by-step explanation:

Calculate the area of the square, the area of the circle, then subtract the area of the circle from the area of the square.

Area of square = 16 x 16 = 256 ft²

Area of circle = $\pi$ r²

radius = 16 ÷ 2 = 8

⇒ Area of circle = 3.14 x 8² = 200.96 ft²

Shaded area = 256 - 200.96 = 55.04 ft²
