X is the number of hours to burn 450 calories:
<em>equality method:</em>
600 calories * 1 hour  = 450 calories * x hours
x hours = 450/600 calories * 1 hour 
x = 0.75 
So, she needs 0.75 hours (45 minutes) to burn 450 calories
<em>
Inequality method:
</em>600x > 450
x > 450/600
x > 0.75
So, she needs at least 0.75 (45 minutes) to burn at least 450 calories.

Hope this Helps! :D

What is the distributive property of 4+10
IgorC [24]

Answer:

  2(2 +5)

Step-by-step explanation:

We presume you want to rewrite the expression making use of the distributive property. For that, it is helpful to find a factor common to the two terms. The GCD of 4 and 10 is 2, so we can factor that out:

  4 + 10 = 2(2 +5)

_____

Of course, you can use any factor you like. It doesn't need to be an integer.

  = (1/3)(12 +30)

  = 0.4(10 +25)

  = 4(1 +2.5)

R = sec(θ) − 2cos(θ), where -π/2 &lt; θ &lt; π/2
Alex

Answer:

  y = (x/(1-x))√(1-x²)

Step-by-step explanation:

The equation can be translated to rectangular coordinates by using the relationships between polar and rectangular coordinates:

  x = r·cos(θ)

  y = r·sin(θ)

  x² +y² = r²

__

  r = sec(θ) -2cos(θ)

  r·cos(θ) = 1 -2cos(θ)² . . . . . . . . multiply by cos(θ)

  r²·r·cos(θ) = r² -2r²·cos(θ)² . . . multiply by r²

  (x² +y²)x = x² +y² -2x² . . . . . . . substitute rectangular relations

  x²(x +1) = y²(1 -x) . . . . . . . . . . . subtract xy²-x², factor

  y² = x²(1 +x)/(1 -x) = x²(1 -x²)/(1 -x)² . . . . multiply by (1-x)/(1-x)

  \boxed{y=\dfrac{x\sqrt{1-x^2}}{1-x}}

__

The attached graph shows the equivalence of the polar and rectangular forms.

*PLEASE ANSWER TY* What is the area of minor sector DFE?
FinnZ [79.3K]

Answer:

x ≈ 34.88 square cm

Step-by-step explanation:

Solve by proportional formula:

Area of a sector/area of circle* = sector central arc measure/360

*area of a circle = πr²

x/(53.29π) = 75/360

x/53.29π = 0.2083

x = 11.1020833π

x = 34.8782233

x ≈ 34.88 square cm
