Answer 1

Answer:

(3x +2)° + 28° = 180°

=> 3x + 30 = 180

=> 3x = 180–30

=> x = 150/3

=> x = 50

You begin painting your house with 10 gallons of paint you purchased at the hardware store. Each gallon of paint covers 400
square feet of surface area. If g is the gallons of paint used for painting x square feet, which type of model would best describe the
relationship between g and x?
A)
linear
B)
radical
quadratic
D)
exponential

Answers

Answer:

A)  linear

Step-by-step explanation:

Let the gallons of paint be represented by g, and the area by x.

Each gallon of paint covers 400 square feet of surface area.

⇒ x = 400g

So that; when g = 1,

x = 400 square feet

when g = 5,

x = 400 x 5

  = 2000 square feet

when g = 10,

x = 400 x 10

 = 4000 square feet

The relationship between the variables is linear because g and x increases at a constant rate.

Answer:

Keplers Third Law

Step-by-step explanation:

Kepler's Third Law relates the period of an orbit to the radius of an orbit, if the orbit is circular, and to the semimajor axis if the orbit is elliptical.

Let's derive it for a circular orbit, assuming a mass m is orbiting a mass M, with r being the radius of the orbit.

ΣF = ma

GmM/r2 = mv2/r

Cancelling the m's and a factor of r gives:

GM/r = v2

We can bring in the period using:

v = 2πr / T

This gives GM/r = 4π2r2/T2

Re-arranging gives:

Kepler's Third Law: T2 = (4π2/GM) r3

For an system like the solar system, M is the mass of the Sun. So the constant in the brackets is the same for every planet, and we get the relationship that the period of the orbit is proportional to r3/2.

The same with satellites orbiting the Earth - in that case M is the mass of the Earth, but again the larger the orbit the larger the period.

Answer:

h=−6.28r2+s/6.28r

Step-by-step explanation:

Step 1: Flip the equation.

6.28hr+6.28r2=s

Step 2: Add -6.28r^2 to both sides.

6.28hr+6.28r2+−6.28r2=s+−6.28r2

6.28hr=−6.28r2+s

Step 3: Divide both sides by 6.28r.

6.28hr/6.28r=−6.28r2+s/6.28r

h=−6.28r2+s/6.28r

a) The unknown is the price of a large pizza

b)  Each pizza cost is positive,

c) The the price of a pizza be p,

so the price of one pizza is p

d) The expression is  

6 pizzas minus 3 dollar off each pizza

6p -3p

e) Set this equal to the total cost

6p -3p= 38.94

f) Combine like terms

3p = 38.94

Divide each side by p

3p/3 = 38.94/3

p = 12.98

The price of each pizza before discount is 12.98

Because if it can eat 2/5's in 1/2 hours, then if it eats for 1 whole hour or 2/2's it will be able to eat 4/5's of it's own body weight.

Just imagine that one half hour is 1 and if you add two half hours together it makes one complete hour or 2/2. So just multiply it by 2 cause it was eating for two half hours.
