What is the value of sin A for this triangle?

2 answers:

The answer is ~0.556

Sin= opposite over hypotenuse.

To find the hyp., you use a squared plus b squared = c squared.

4+9=13

Square root of 13 is ~ 3.605

Now that you have your hyp, you can divide.

2 divided by 3.605 ~ 0.556 (rounded)

Hope this helps!!

The sine of the angle is the ratio of the opposite side to the hypotenuse. The hypotenuse of this triangle can be computed from the Pythagorean theorem:
.. AB = √(AC^2 +BC^2) = √(9 +4) = √13 . . . . cm
Then the ratio of opposite side BC to the hypotenuse AB is
.. sin(A) = BC/AB = 2/√13

Corresponds to the 3rd selection.

What is -2 1/2 + 1 1/3 in fraction form?

olga nikolaevna [1]

$-2\frac{1}{2} +1\frac{1}{3}=\frac{-1}{6}$

Solution:

Given expression is $-2\frac{1}{2} +1\frac{1}{3}$ .

Let us first convert mixed fraction into improper fraction.

$-2\frac{1}{2} +1\frac{1}{3}=\frac{(-2\times 2) +1}{2} +\frac{(1\times 3) + 1}{3}$

$=\frac{-4 +1}{2} +\frac{3 + 1}{3}$

$=\frac{-3}{2} +\frac{4}{3}$

Take LCM for the denominators (LCM of 2, 3 = 6) and make the same.

$=\frac{-3\times3}{2\times3} +\frac{4\times2}{3\times2}$

$=\frac{-9}{6} +\frac{8}{6}$

$=\frac{-1}{6}$

$-2\frac{1}{2} +1\frac{1}{3}=\frac{-1}{6}$

Hence the fraction form of $-2\frac{1}{2} +1\frac{1}{3}$ is $\frac{-1}{6}$ .

Whoever answers first i will mark as brainiest

vfiekz [6]

Answer:

As shown in picture,

volume of cone V = base area x height x (1/3) = pi x (4/2)^2 x 6 x (1/3) = 8 x pi

volume of cup V = base area x height = pi x (3/2)^2 x 3 = 6.75 x pi

(all the volumes are in cubic inches)

A - Incorrect

24 pack of cups: V = 24 x 6.75 x pi = 162 x pi

21 pack of cones: V = 21 x 8 x pi = 168 x pi

162 x pi < 168 x pi

B - Correct

12 pack of cups: V = 12 x 6.75 x pi = 254.5 > 250

C - Correct

14 pack of cones: V = 14 x 8 x pi =351.9 > 350

D - Correct

Volume of cylinder 8 tall, 6 wide: V = pi x (6/2)^2 x 8 = 72 x pi

12 pack of cups: V = 12 x 6.75 x pi = 80.4 x pi > 72 x pi

Hope this helps!

Can someone pls help me

Irina18 [472]

Answer:

6π Km

Step-by-step explanation:

The arc length is calculated as

arc = circumference of circle × fraction of circle

= 2πr × $\frac{120}{360}$

= 2π × 9 × $\frac{1}{3}$

= 18π × $\frac{1}{3}$

= 6π Km ← exact value
