Cameron wanted to buy some pens.They had 18 pens for $ 6.84 for 30 pens for $8.40 which is a better deal?

romanna [79]

$6.84 divided by 18= .38 which means 38 cents per pen

$8.40 divided by 30= .28 which means 28 cents per pen

so $8.40 for 30 pens is a better deal than 18 pens for $6.84 by ten cents.

Segment addition postulate What’s the answer?

Free_Kalibri [48]

$\bf Step-by-step~explanation:$

Keep in mind: The entire line segment (VX) is equal to 14.

$\bf Step~1:$

Let's see how the line segment looks like first.

Line segment VX is 14 units long.

______________

V X

W is on the line segment somewhere, and VW is equal to 3.

3 ?

______________

V W X

$\bf Step~2:$

We have to solve for the ?. Let's put ? as x. So now we are solving for x.

We have to set up our equation like this:

x + 3 = 14

Since our unknown value plus 3 is equal to 14, we have to subtract 3 from 14 to get our answer.

14 - 3 = 11

3 11

______________

V W X

$\large\boxed {\bf Our~final~answer: ~WX=11}$

The central angle of a circle is equal in measure to one radian when the corresponding arc length is equal to which of the follo

irinina [24]

The formula to find the arc length L is
L = r*theta
where r is the radius and theta is the central angle in radians (this formula will not work if theta is in degrees)

If the central angle is 1 radian, then theta = 1 and
L = r*theta
L = r*1
L = r
So the arc length is the same as the radius

Answer: Choice A) The radius of the circle
