Answer:

$\large \boxed{\text{5.2 lb$\cdot$in}^{-2}}}$

Step-by-step explanation:

In a direct proportion,

Pressure = constant × temperature

p = kT

We can use the initial conditions to find the value of k, and then calculate the pressure at the new temperature.

1. Determine the value of k

Data:

p₁ = 6 lb·in⁻²

T₁ = 440 K

Calculation:

$\begin{array}{rcl}p_{1} & = &k \times T_{1}\\6 & = &k \times 440\\k & = & \dfrac{6}{440}\end{array}$

2.Calculate the new pressure

$\begin{array}{rcl}p_{2} & = &k \times T_{2}\\& = &\dfrac{6}{440} \times 380\\\\& = & \mathbf{5.2}\end{array}\\\text{The new pressure is $\large \boxed{\textbf{5.2 lb$\cdot$in}^{\mathbf{-2}}}$}$

You are dealt one card from a 52-card deck. find the probability that you are dealt an eight or a black card.

Lostsunrise [7]

Number of black cards = 52 ÷ 2 = 26

Number of non-black eight = 2

Total number of cards that are eight or black = 26 + 2 = 28

P(eight or black) = 28/52 = 7/13

Answer: 7/13

To get to zoo from the school the kids have to ride some buses if there are 7 buses and each bus have three adult supervisors to

loris [4]

There are 21 supervisors in total

Solution:

Given that, To get to zoo from the school the kids have to ride some buses

There are 7 buses and each bus have three adult supervisors to guard the children

To find: Number of supervisors in total

From given,

Total number of buses = 7

Number of supervisor in 1 bus = 3

Therefore, total number of supervisors can be found by multiplying total number of buses with number of supervisors in 1 bus

$\text{Total supervisor} = \text{Total number of buses} \times \text{Number of supervisor in 1 bus}$

Substituting the values we get,

$Total\ Supervisor = 7 \times 3 = 21$

Thus there are 21 supervisors in total
