The diameter d in inches of a rope required to lift a weight of w tons is given by the function d = 10w/ π . How much weight can
Ilia_Sergeevich [38]

Answer:

Option D) 1.26 tons

Step-by-step explanation:

we have

d=\frac{10w}{\pi}

where

d is the diameter of a rope in inches

w is the weight in tons

we have

d=2(2)=4\ in ----> the diameter is two times the radius

substitute the value of d and solve for w

4=\frac{10w}{\pi}

w=\frac{4\pi}{10}=0.4\pi\ tons

assume

\pi =3.14

0.4(3.14)=1.26\ tons

How many triangles will be in the 5th set of triangles?
tia_tia [17]

Answer:

25.

Step-by-step explanation:

I am assuming you only mean the small triangles, not the composite ones.

The  second  triangle set has 3 triangles on bottom row and 1 on the top - total 4.

The 3rd triangle set has 5 triangles on the bottom , 3 on the next up and 1 on the top  - total  9

Following the pattern 4th set will have the number of triaNGLES

7 + 5 + 3 + 1 = 16.

So the 5th will have 9 + 7 + 5 + 3 +1 = 25 triangles.
