Answer:

6.7cm

Step-by-step explanation:

We apply Pythagoras Theorem twice.

First we find out the diagonal of the base of the cuboid.

The diagonal of the base = sqrt (2^2+4^2) = sqrt (20).

Then we find out AB by applying Pythagoras Theorem.

AB^2 = 5^2 + [sqrt (20)]^2

AB^2 = 45

AB = 6.7cm (correct to 1 decimal place)

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

$\pi =3.14$

$0.4(3.14)=1.26\ tons$

When constructing parallel and perpendicular lines, how are the steps similar?

Schach [20]

Similar steps:

1. You need to draw a reference line first( It's trivial but hey, it's similar)

2. You need to draw the other line with pre-defined slope( parallel with same slope, perpendicular with the product of the slope to be -1)
