Answer:

A=4cm

ok to do this we do the formula

A=PiR^2

A=3.14*4^2

A=3.14*16

A=50.24

and the area of circle B is 4 times the area of a so

50.24*4=200.96

200.96=3.14*X^2

Since  r  is on the right side of the equation, switch the sides so it is on the left side of the equation. 3.14 ⋅ r 2 = 200.96  Divide each term by  3.14  and simplify.

r 2 = 64

r=8

CIRLCE A=50.24

CIRLCE B=8

Solve the following quadratic-linear system of equations. y=x^2-x-6 and y=2x-2
Keith_Richards [23]

You can do substitution 2x-2=x^2 -x -6; isolate all terms on one side 0= x^2 -x-2x -6+2; combine like terms x^2 -3x -4=0; factor the quadratic (x-4)(x+1)=0; each term is zero x-4=0 so x=4 and x+1=0 so x=-1. Now, y=2•4-2=6 and y=2•(-1) -2= -4 ; solutions for the system are ( 4,6) and ( -1, -4)

a medication prescription states 1/4 tablet twice a day per 20kg the peson weight is 211 pounds. how many tablets should be take
Black_prince [1.1K]
<h2>Hello!</h2>

The answer is: 1.187 tablets each time (twice a day)

<h2>Why?</h2>

From the statement we know that 0.25 tablet (1/4) should be taken twice a day per 20 kg, it makes 0.5 table a day, per 20 kg.

First, we need to convert the given weight unit (pounds) to kg:

1 Pound=0.45Kg

So,

211Pounds*\frac{0.45Kg}{1Pound}= 94.95Kg=95Kg

A weight of 95 Kg, means 4.75 times more than the given information of 0.5 table a day, per 20 Kg

\frac{95Kg}{20Kg}=4.75

Then,

4.75*(0.5)=2.375

So,

For a weight of 95 Kg,  2.375  tablets should be taken a day, or 1.187  tablets each time.

Have a nice day!
