The Volume () of gas vanes inversely to the pressure (P). The volume of gas is 200 cm ^ 3 under pressure of 32 kg/cm^ 2 What wil

WITCHER [35]

Answer:

0.025 Kg/ cm²

Step-by-step explanation:

if two variables vary inversely, there is a negative relationship between both variables. the increase in one variable leads to a decrease in the other variable

the equation that represents inverse proportion :

$y = \frac{b}{x}$

where b = constant of proportionality

to determine the answer in this question :

1. determine constant of proportionality

200 = k / 32

k = 6400

2. Determine the amount of pressure using the constant of proportionality

256, 000 = 6400 / pressure

pressure = 6400 / 256, 000 = 0.025

The mean of a sequence of n numbers is m. If we split the sequence into two sequences of lengths n1 and n2 and compute their mea

Furkat [3]

The mean of a sequence of numbers is the average.

The true statement is: $\mathbf{mn = m_1 \times n_1 + m_2 \times n_2}$

The given parameters are:

$\mathbf{Mean = m}$

$\mathbf{Size = n}$

The mean of a dataset is calculated as:

$\mathbf{Mean = \frac{\sum x}{Size}}$

So, we have:

$\mathbf{m = \frac{\sum x}{n}}$

Multiply both sides by m

$\mathbf{\sum x = mn}$

When the sequence is split into two, we have:

$\mathbf{\sum x_1 = m_1\times n_1}$

$\mathbf{\sum x_2 = m_2\times n_2}$

Where:

$\mathbf{\sum x_ = \sum x_1 + \sum x_2}$

So, we have:

$\mathbf{mn = m_1 \times n_1 + m_2 \times n_2}$

Hence, the true statement is: $\mathbf{mn = m_1 \times n_1 + m_2 \times n_2}$

Mito bakes biscuits. he uses 1/4 cup of flour to coat the countertop and the rolling pin. He also uses 2 1/2 cups of flour for e

Gennadij [26K]

Answer:

Mito can bake 3 batches of cookies.

The amount of flour used to bake cookies = Total flour used - Amount of flour used to coven counter top.

Step-by-step explanation:

Here, the amount of flour used to coat counter top and rolling pin = 1/4 cup

1/4 cup = 0.25 cup

Now, the amount of cup used to bake 1 batch of cookies = 2 1/2 cup

Now, 2 1/2 cup = ( 2 + 1/2 )cup = 2 + 0.5 = 2.5 cup

So, 1 batch of cookies = 2.5 cup

Total amount of flour used = 7 3/4 cups

Now, 7 3/4 cup = (7 + 3/4) cup = 7 + 0.75 = 7.75 cups

The actual amount of flour used to bake cookies

= Total flour used - Amount of flour used to coven counter top.

= 7.75 cup - 0.25 cup = 7.5 cup

Now, the number of batches baked with 7.5 cup $= \frac{\textrm{Total amount of flour used in baking}}{\textrm{Flour used in 1 batch}}$

$= \frac{7.5}{2.5} = 3$

or, the number of batches baked with 7.5 cup is 3 batches.

Hence, Mito can bake 3 batches of cookies.

3/4 of a piece of metal has a mass of 15kg.what is the mass of 2/5 of the piece of metal

olga2289 [7]

3/4=15
let,
total mass is x
x=4×15/3
=20 kg
so, total mass = 20 kg

=2×20/5
=2×4
=8 kg

Hope this helps!
