What is the relationship between all 5 triangles

a slide on the playground is 12 and 1/2 FEET long..... its 3 feet and 7 inches longer then the small slide.... how long is the s

You simply have to add the two numbers together, however, you have to convert everything into inches only. You know that there are 12 inches in one foot. To calculate the length of the longer slide, it is simply doing 12 feet TIMES 12 (since there are 12 inches in one foot). This makes 144 inches. Add 1/2 feet in there, this is adding 1/2 of 12 inches, which is 12/2=6 inches. The long slide is therefore 144+6= 150 inches. Now you want to convert 3 feet and 7 inches into inches only. 3 feet TIMES 12 = 3x12=36 inches. Add 7 inches to this, and you will get 36+7=43 inches. To know how long the small slide is, subtract 43 inches from 150 inches, and this will give you 150-43=107 inches. So, the small slide is 107 inches. :)

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

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.
