Answer 1

Answer:

4/5

Step-by-step explanation:

{(2/5) / (1/2)} ×1

= (2/5)÷(1/2)

= 2/5×2/1

= 4/5

Answer 2

Answer:

4/5

Step-by-step explanation:

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.

[tex]\frac{2}{5} * 1=2/5\\\frac{2}{5} *2=4/5[/tex]

Answers

Y would = 12 does this help with your question

Answer:

y = 12

Step-by-step explanation:

The two bars between x mean absolute value, so all negatives turn into positives because absolute value just means the total distance from zero.

y = |x| +6

y = |-6|+6

y = 6+6

y = 12

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

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.

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.

½(10x - 18) - 13x = -2x + 7 - 6x

Distribute

5x -9 -13x = -2x +7 -6x

Combine like terms

-8x -9 = -8x+7

Add 8x to each side

-8x -9 +8x = -8x+7+9x

-9 = 7

Question 1 :In order to convert this equation to Slope-Intercept Form, you must first isolate y.

What is the first step in isolating y?

6x+7y=14

Question 3: Convert to Slope-Intercept Form to graph 3x+5y=10.

Answers

Answer:

Step-by-step explanation:

Add -6x to both sides

6x + 7y + − 6x = 14 + − 6x

7y = − 6x + 14

Divide both sides by 7

7y / 7 = − 6x + 14 / 7

y = − 6 / 7x + 2

Answer

y = −6 / 7x + 2

Graph question: answer would be :  

[tex]y = \frac{-3}{5} x+ 2[/tex]

Place a point on (0,2) and a point on (5, -1)

In order to convert 6x+7y=14 equation to Slope-Intercept Form is use the subtraction property of equality to subtract 6x from both sides of the equation

What is Slope-Intercept?One of the four additional techniques for figuring out any straight line's equation is the slope-intercept form. Typically, straight lines are shown as y = mx+c. The x and y variables are said to have a maximum power of unity by this common straight line equation. As a result, x = x1 and y = y1. Additionally, this demonstrates that only linear equations can be solved using the slope-intercept form. You ought to be able to solve linear equations with two variables. The graph of such equations is a straight line, as you should be aware of. Additionally, you need to be confident in your understanding of the y-intercept, x-intercept, and slope properties of linear equations.

6x + 7y = 14 to rewrite in the form y = mx + b,

make y the subject of the equation 6x + 7y = 14

7y = -6x + 14

divide both sides by 7

y = (-6/7)x + 2

The slope is -6/7 while the intercept is 2.
