Their least common multiple is  90 .

90 = 5 x 18

90 = 2 x 45

Answer:

Step-by-step explanation:

we are given that given that  1/2T = 60 so T=120°  so we also know R = 120 °

then W and S are also the same angle so 2z +240 = 360

2z = 120

z=60

W =60 °

S = 60 °

which makes sense b/c the small triangles also tell us that the sharp angles of the small triangles are 30 °  for the  30 , 60 90 triangle.

so by complementary angle we know that c = 60 °

we also know that a = 12 b/c all the small triangles are identical.  

we also know that b= 90 °  also by complementary angle

we can also solve for length of SW and RT

cos(30)=adj / Hyp  

12*Cos(30) = adj

12*\sqrt{3} /2 = adj

but the adjacent side is 2 times for SW so

SW = 12 \sqrt{3}

for RT

sin(30) = Opp / hyp

12 * Sin(30) = Opp

12 * 1/2 = opp

but RT is times 2 again, sooo

RT = 12

you can also solve for the area of SRWT = 12 *12 = 144 units  (what ever unties 12 is in)   hmmm

That's all I can think of to solve for now  :)

The graph of h (x) =|x- 10|+ 6 is shown. On which interval is this graph increasing? A. (–∞, 6) B. (–∞, 10) C. (6, ∞) D. (10, ∞)
gladu [14]

Answer:

D.

Step-by-step explanation:

The graph increases when y hits its lowest point and then starts to go back up again. In this case, when x = 10, it starts to go back up again.

Hello!

First you have to find the volume of the cylinder

To find the volume of a cylinder you use the equation

V =  \pi  r^{2} h

V is volume
r is radius
h is height

Put in the values you know and 3.14 for pi

V = 3.14 *  3^{2} * 7

Square the number

V = 3.14 * 9 * 7 

Multiply

V = 197.82
------------------------------------------------------------------------------------------------------
Next you find the volume of the sphere

To find the volume of a sphere you use the equation

V =  \frac{4}{3}  \pi  r^{3}

V is volume
r is radius

Put in the values you know and 3.14 for pi

V =  \frac{4}{3} * 3.14 *  3^{3}

Cube the number

V =  \frac{4}{3} * 3.14 * 27

Multiply

V = 113.04
------------------------------------------------------------------------------------------------------
Finally you subtract the two volumes from each other

197.82 - 113.04 = 84.78
------------------------------------------------------------------------------------------------------
The answer is C)84.78

Hope this helps!
