Answer:

$36√(3) -12\pi$

Step-by-step explanation:

The area of the shaded portion, we have to calculate.

Now, join C and O to form two right triangles Δ AOC and Δ BOC.

Now, from Δ AOC,

$\tan 60 = (AC)/(AO) = (x)/(6)$

⇒ x = 6√3

So, area of Δ AOC = $(1)/(2) * 6 * 6√(3) = 18√(3)$

Due to symmetry area of Δ BOC will also be 18√3.

Now, area of quadrilateral OACB is 2 × 18√3 = 36√3

Now, area covered by the arc AB about center O will be $(120)/(360) * \pi r^(2) = 12\pi$

Therefore, the area of the shaded portion is $36√(3) -12\pi$ (Answer)

36\sqrt{3} -12\pi

at the park, people can climb a rope ladder to its top. rosa climbed 2/8 of the up the ladder. Justin climbed 2/6 of the way up the ladder. who climbed higher on the rope ladder?

Answers

well if you make the denominater of the fraction the same, aka finding the lowest common multiple you can find out so what you do is 8 and 6 both go into 24 8 goes into 24 3 times and 6 goes 4 times so you multiply the numerator by how many times the denominator goes into the LCM(lowest common multiple) and get 6/24 and 8/24 meaning justin climbed higher

In ΔNOP, the measure of ∠P=90°, the measure of ∠N=83°, and NO = 83 feet. Find the length of OP

Answers

Answer: Length OP = 82.38 feet

Step-by-step explanation: Given that the ΔNOP, the measure of ∠P=90°, the measure of ∠N=83°, and NO = 83 feet.

We can find the length of OP by using trigonometry ratio since it is a right angle

NO = hypothenus and

OP = opposite

Sin 83 = OP/NO

Sin83 = OP/83

OP = 83sin83

OP = 82.38 feet

Simplify the ratio:26:65

Answers

$(26)/(25)$

Divide both numerator and denominator by "13", and you get,

= $(2)/(5)$

And thats your simplified answer

Final answer:

In order to simplify the ratio 26:65, we find the greatest common divisor of 26 and 65, which is 13. Dividing both numbers of the ratio by this divisor, the simplified ratio becomes 2:5.

Explanation:

To simplify the given ratio 26:65, we need to find the greatest common divisor (GCD) of the two numbers and divide each of them by this GCD. The GCD of 26 and 65 is 13. Hence, we divide both numbers of the ratio by 13.

26 ÷ 13 = 2

65 ÷ 13 = 5

Therefore, the simplified form of the ratio 26:65 is 2:5.

Estimate product
126.12 and 2.2

Answers

so estimate
round to whole numbers
126 times 2
we know that times 2 is just add them twice
126 times 2=126+126=252
aprox 252

I might round 126.12 UP to 130 and 2.2 DOWN to 2, then multiply 130 x 2 to get 260. This UNDER-estimates the true answer, 277.4, because rounding 126.12 up to 130 is only a slight increase percentage-wise (about 3%) whereas rounding 2.2 down to 2 is a greater decrease percentage-wise (10%).
