The formula tells you
.. V = constant * T/P
That is, volume is proportional to absolute temperature and inversely proportional to pressure.
When temperature increases from 273 K to 300 K, volume is increased by the factor 300/273.

When pressure increases from 2 atm to 3 atm, volume is changed by the factor 2/3.

The new volume will be
.. (10 L) * (300/273) * (2/3) = 2000/273 L ≈ 7.3 L

There are x number of students at helms. If the number of students increases by 7.8% each year, how many students will be there
vodomira [7]

There will be 1.078x students next year and equation is number of students in next year = x + 7.8% of x

<h3><u>Solution:</u></h3>

Given, There are "x" number of students at helms.  

The number of students increases by 7.8% each year which means if there "x" number of students in present year, then the number of students in next year will be x + 7.8% of x

Number of students in next year = number of students in present year + increased number of students.

\begin{array}{l}{\text { Number of students in next year }=x+7.8 \% \text { of } x} \\\\ {\text { Number of students in next year }=x\left(1+\frac{7.8}{100}\right)} \\\\ {\text { Number of students in next year }=x(1+0.078)=1.078 x}\end{array}

Thus there will be 1.078x students in next year

HELP ME!! whats the answer? no goofing around pleaze
valentinak56 [21]

Answer: A

Step-by-step explanation:

\frac{6.3\cdot \:10^8}{9\cdot \:10^2}

=\frac{6.3\cdot \:10^6}{9} --> Exponent rule for division, 10^8/10^2 = 10^6

= 700,000 --> In scientific notation, 7.0×10^5

A right prism has height 7½ and triangular bases with sides of length 5, 12, and 13 What is the: Total Surface Area of the Prism
sdas [7]

Given:

A right prism has height 7½ and triangular bases with sides of length 5, 12, and 13.

To find:

The total surface area of the prism.

Solution:

We have,

Height of prism = 7½ = 7.5

Sides of triangular base are 5, 12, 13. These sides of Pythagorean triplets because

5^2+12^2=13^2

25+144=169

169=169

So, the base of the prism is a right triangle.

Area of a triangle is

Area=\dfrac{1}{2}\times base \times height

A_1=\dfrac{1}{2}\times 5\times 12

A_1=30

The area of the base is equal to the area of the top, i.e., A_2=30 sq units.

Perimeter of the base is

P=5+12+13

P=30

The curved surface area of the prism is

CSA=\text{Perimeter of the base}\times \text{Height of the prism}

CSA=30\times 7.5

CSA=225

Now, the total area of the prism is

A=A_1+A_2+CSA

A=30+30+225

A=285

Therefore, the total surface area of the triangular prism is 285 square units.
