It can be shown as {x | x < 7, x > 7}

A área do círculo mede 196 π cm². Qual a medida do seu raio?

AleksandrR [38]

Hey there!!

The area of a circle = πr²

The area is given as 196π

Hence,

196π = πr²

... r²= 196

... r = √196

... r = 14

<em>Hence, the radius is 14 cm. </em>

<em>Hope it helps!</em>

Solve the Inequality.

$\blue{\textsf{\textbf{\underline{\underline{Answer:-}}}}$

x<-4

$\blue{\textsf{\textbf{\underline{\underline{How\:to\:Solve:-}}}}$

First, add 6x on both sides:

-2x+3+6x<-13

Add the x's:

4x+3<-13

Now, subtract 3 on both sides:

4x<-13-3

4x<-16

Divide by 4 on both sides:

x<-4

So the values of x that are less than -4 will make the given inequality true.

If 6 people want to share a 30 pound bag of beans equally by weight how many pounds of beans should each person get? Between wha

sertanlavr [38]

Answer:

The 6 people would each get 5lb. of beans. 5 lies between 4 and 6.

Step-by-step explanation:

To get the answer to this problem, all you have to do is divide the total pounds of beans by how many people there are. 30 ÷ 6= 5, so each person would get 5 pounds. Since 5 comes between 4 & 6, you can use that as your answer.
