Answer:

Answer:

For converging lens

object distance u = - 2.0cm

Focal length f = 5.0cm

From lens formula

m=

m=

=3

Size of image = size of object x Magnification

= 2 x .10 = 2.0cm

For diverging lens

object distance u = 140 - 120 = 20 cm

focal length f = -30 cm

frac{1}{v}+\frac{1}{20}=-\frac{1}{30}

v = -12 cm

m = 12/20 = 0.6

size of final image = .6 x 30 = 18 cm

Whats would the slope of (-3,10),(-5,-4) coordinates be?
valentina_108 [34]

Answer:

The slope is 7.

Step-by-step explanation:

Let the given points are (p, q)= (-3, 10) & (r, s) =(-5, -4).

Then the slope (m) = (s-q)/(r-p)

⇒ m = (-4 -10)/(-5-(-3))

⇒ m = (-14) / (-5 +3)

⇒ m = -14/- 2

⇒m = 7

Hence the slope is m =7 .

Tickets to the fashion show we're $2.50 for adults and $1 for students. The receipts were $674 for 302 tickets sold. How many ad
rodikova [14]

Answer:the number of adults that attended the show is 248

the number of students that attended the show is 54

Step-by-step explanation:

Let x represent the number of adults that attended the show.

Let y represent the number of students that attended the show.

Total number of tickets that were sold is 302. This means that

x + y = 302

Tickets to the fashion show were $2.50 for adults and $1 for students. The receipts for all the tickets were $674. This means that

2.5x + y = 674 - - - - - - - - - 1

Substituting x = 302 - y into equation 1, it becomes

2.5(302 - y) + y = 674

755 - 2.5y + y = 674

- 2.5y + y = 674 - 755

- 1.5y = - 81

y = - 81/- 1.5

y = 54

Substituting y = 54 into x = 302 - y, it becomes

x = 302 - 54 = 248
