A ball bearing has mass 0.44 pounds. 1 kg = 2.2 pounds. <br>

torisob [31]

Answer:

(i) 0.2 kg

(ii) kg/cm³

(b) 2.29 kg

Step-by-step explanation:

This problem gives you relations between units, and the formulas for density and mass. It is asking you to make use of these relations in various mass and density calculations.

The relationship between kg and pounds can be used to write a units conversion multiplier. It will have numerator equal to denominator, but will have units such that multiplying by it will give the units you want.

0.44 pounds × multiplier = __ kg

0.44 pounds × (1 kg)/(2.2 pounds) = (0.44/2.2)(1 kg)

0.44 pounds = 0.2 kg

The formula can be used to find the units of interest:

Density = mass/volume

units of density = (units of mass)/(units of volume)

units of density = kg/cm³

Using the given formula with the given value of L, we find the volume to be ...

V = 4(1.40 cm)(3 -1.40 cm)² = 14.336 cm³

Then the mass is ...

mass = volume × density

mass = (14.336 cm³)×(0.160 kg)/(1 cm³) = 2.29376 kg

The mass is about 2.29 kg.

<em>Additional comment</em>

Often you will see density in terms of kg/m³ or g/cm³. Water has a density of about 1 g/cm³ or 1000 kg/m³. The most dense non-radioactive element in the periodic table is osmium, with a density of about 22.6 g/cm³, or 0.0226 kg/cm³. The material in part (b) of this problem has a density about 7 times that, so is clearly not from Earth.

Graph the image of triangle PQR after a reflection across the line y = 2

ololo11 [35]

Answer: Refer to the diagram below

P ' is at (-7, 9)
Q ' is at (1, 9)
R ' is at (-6, 4)

================================================

Explanation:

The diagram shows how point R moves to R'. We move up 2 units going from R(-6,0) to (-6,2). This lands us on the line of reflection. Then we move another 2 units up to land on (-6,4) which is the location of point R'.

The other points P and Q follow the same idea. Though the distances will be different from R. For P and Q, we'll move 7 units up to arrive at the line of reflection, then another 7 units to arrive at the proper locations of P' and Q', which are (-7,9) and (1,9) respectively.
