There Is A Proportinal Relationship Between The Volume Of A Sample Of Helium In Liters And The Mass Of

Answers

Answer 1

The constant of proportionality in this relationship is 5.6.

Proportional relationship:

Proportional relationship is a relationship between two variables where there ratios are equivalent.

The variables are as follows:

v = the volume of a sample of helium in litters

m = the mass of that sample in grams

Therefore,

v = km

where

k = constant of proportionality

Therefore,

k = 28 / 5

k = 5.6

Area of a prism is area of cross section x length. Area of triangle is 1/2 base times height. Surely that makes it easy for you now m8.

Answer and Step-by-step explanation:

First, lets write down the volume of an equilateral triangular prism.

The volume of a triangular prism is as follows:

[tex]V = \frac{1}{2} * b * h * l[/tex]

Where:

b = base length (edge)

h = height

l = length.

[tex]V = \frac{1}{2} * 4*10*2\sqrt{3} = 40\sqrt{3} = 69.2820[/tex]

Step-by-step explanation:

The original blueprint of a concrete patio has a scale of 2 inches = 3 feet.
Victoria wants to make a new blueprint of the patio with a
length of 16.8 inches.

a. What is the scale for the new blueprint?

b. What is the width of the blueprint with the new scale?

Answers

The scale factor for the new blueprint will be - {K} = 3/2 and the width of the blueprint with the new scale will be 25.2 feet.

What is ratio?

Ratio is a quantitative relation between two amounts showing the number of times one value contains or is contained within the other.

Given is that the original blueprint of a concrete patio has a scale of

2 inches = 3 feet. Victoria wants to make a new blueprint of the patio

with a length of 16.8 inches.

{A} -

It is given that -

2 inches = 3 feet

1 inch = (3/2) feet

The scale factor for the new blueprint will be -

{K} = 3/2

{B} -

The width of the blueprint with the new scale will be -

{w} = 3/2 x 16.8

{w} = 3 x 8.4

{w} = 25.2 feet

Therefore, the scale factor for the new blueprint will be - {K} = 3/2 and the width of the blueprint with the new scale will be 25.2 feet.

Step by Step: Solve:
3x + 2 ( 2x + 9 ) = 4

Answers

Answer:

3x + 2 (2x + 9) = 4

3x + 4x + 18 = 4

7x + 18 = 4

7x = -14

x = -2

Step-by-step explanation:

i think it should be -2. if im wrong sorry

3x+2 (2x+9) = 4

Take care of the parenthesis to get the following

3x + 4x + 18 = 4

Add the X values

7x + 18 = 4

Take 18 from both sides so it looks like this

7x = 4 - 18

From this you’ll get this

7x = -14

Divide both sides by 7

x = -14 / 7

Simplify

X = 7 * - 2 / 7

Simplify

X = -2
