The volume of a gas held at constant temperature varies inversely with the pressure of the gas. If the volume of the gas is 1200 cubic centimeters then the pressure is 200 millimeters of mercury, what is the volume when the pressure is 800 ml?

Answers

Answer:

300

Step-by-step explanation:

The volume of the gas varies inversely as the pressure

V= k/p

K= VP

= 1200×200

= 240,000

Therefore the volume when the pressure is 800

K= VP

240000= V×800

V= 240000/800

= 300

Hence the volume is 300 cubic centimeters

Help..? Pleaseee , it has to do with the Pythagorean Theorem. But I have no idea how to do it

Answers

Pythagorean Theorem is

a ²+ b ² = c ²

a and b are the shorter sides, while c is the hypotenuse, or longest side. Let’s say the side we are looking for is “b”.

Let’s first rearrange the equation, then sub in.

a ²+ b ² = c ²
b ² = c ²- a ²
b = √ (c ²- a ²)
b = √(17 ²- 15 ²)
b = √(289-225)
b = √ 64
b = 8

Se va a colocar una escalera que mide 5 metros (m) de longitud sobre una pared. El fabricante de la escalera recomienda que, por seguridad, el ángulo que forme la escalera con el piso sea de 78°, ¿Cuál será la distancia sobre el piso del pie de la escalera a la pared?

Answers

Answer:

4.9 m

Step-by-step explanation:

Resolvemos la pregunta anterior usando la función trigonométrica de seno

sin θ = Opuesto / Hipotenusa

θ = 78 °

Hipotenusa = Longitud de la escalera = 5 m

Opuesto = Distancia sobre el suelo = x

sin 78 = x / 5m

Multiplicar cruzada

x = sin 78 × 5 m

x = 4.8907380037m

Aproximadamente

= 4.9 m

Biscuits are sold in in packs of 8. How many packs should you buy if you need 56 biscuits.

Answers

Answer:

7

Step-by-step explanation:

you just divide 8/56= 7

-----------------------------------------------------------------------------

Step 1:

Start by setting it up with the divisor 56 on the left side and the dividend 8 on the right side like this:

           

 56⟌8    

Step 2:

The divisor (56) goes into the first digit of the dividend (8), 0 time(s). Therefore, put 0 on top:

   0    

 56⟌8    

Step 3:

Multiply the divisor by the result in the previous step (56 x 0 = 0) and write that answer below the dividend.

      0    

 56⟌8    

   0    

Step 4:

Subtract the result in the previous step from the first digit of the dividend (8 - 0 = 8) and write the answer below.

   0    

 56⟌8    

    -0  

     8    

the answer to 8 divided by 56 calculated using Long Division is: 7

a dime is dropped from a building at 1.024 ft . if the equation for height as a function of time is h(t)=-16t^2+ initial height where is t is time in seconds and h(t) is height in feet, how many seconds will it take for the dime to hit the ground?

Answers

Answer:

The dime hits the ground after 8 sec.

Step-by-step explanation:

Set h(t) = -16t^2 + h(0) equal to 0:  -16t^2 + 1,024 ft = 0, or:

16t^2 = 1,024 ft, or:

 t^2 =  64 ft^2

Then t = +8 sec

The dime hits the ground after 8 sec.

Jack tool out a 6-year loan for $25,000 to purchase a boat at a 4.5% interest rate. If the interest is compounded monthly, what will he have paid total over the course of the loan?

Answers

Answer:

A = $32,732.58  

A = P + I where

P (principal) = $25,000.00

I (interest) = $7,732.58

Step-by-step explanation:

Given data

Time= 6 years

Principal=  $25,000

Rate= 4.5%

First, convert R as a percent to r as a decimal

r = R/100

r = 4.5/100

r = 0.045 rate per year,

Then solve the equation for A

A = P(1 + r/n)^nt

A = 25,000.00(1 + 0.045/12)^(12)(6)

A = 25,000.00(1 + 0.00375)^(72)

A = $32,732.58

Find area of the composite figure..

Answers

Answer:

627square inches

Step-by-step explanation:

Area of the composite figure.. = area of triangle + area of parallelogram

Since the triangle is an equilateral triangle;

Area of the triangle = r²sintheta

Area of the triangle = 18²sin60

Area of the triangle = 324sin60

Area of the triangle  = 324(0.8860)

Area of the triangle = 280.584 square in

Area of the triangle = 281 square inches

Area of parallelogram = absintheta

Area of parallelogram = 20(20)sin60

Area of parallelogram = 400(0.8660)

Area of parallelogram = 346.4square inches

Area of parallelogram = 346 square inches

Area of the figure = 346  + 281

Area of the figure  = 627square inches

f is inversely proportional to √ g . When f = 8 , g = 25 Work out f when g = 16

Answers

QUESTION :-

f is inversely proportional to √ g . When f = 8 , g = 25 Work out f when g = 16

ANSWER :

By question , f is inversely proportional to square root of g. In mathematical form ,

[tex]\implies f \propto \dfrac{1}{\sqrt g}[/tex]

Let k be constant . So that ,

[tex]\implies f =k \dfrac{1}{\sqrt g}[/tex]

When f = 8 , g is 25. So that ,

[tex]\implies 8= k\dfrac{1}{\sqrt {85}}[/tex]

[tex]\implies k = 8\sqrt{25} [/tex]

Hence the value of constant is 8√25.

So that when g is 16 ,

[tex]\implies f = 8\sqrt{25} \times 1/ \sqrt{16}\\\\\implies f = 8*5 / 4 \\\\\implies \boxed{ f = 10 } [/tex]

Hence the Value of f is 10 .

Write True or False. You can use the measures of the angles formed by two lines and a transversal to determine whether the two lines are parallel.

Answers

Answer:

I think that the answer is true (explanation might not be 100% accurate)

Given that for 2 lines to be parallel, they have to never intersect at any point, meaning they both have to be straight and "facing" the same way. If either line has a tilt/angle of any sort, then they are not parallel.
