If the scale factor between a scale drawing of a rectangle and the real object is 1:3 what would be the ratio of the areas?

Answers

Answer 1

Answer:

The ratio of the areas will be will be 1 : 9

Step-by-step explanation:

The linear scale factor represents a ratio that is used to multiply the dimensions of objects so that accurate geometries can be transferred between real-life and paper.

The linear scale factor is quite different from the area scale factor but related to it in the following way:

The area factor can be obtained by squaring the linear scale factor.

This is Area factor = (Linear scale factor) ^2.

Linear scale factor = (1:3)

Area factor = [tex]1^2 : 3^2[/tex]

Area factor will be 1: 9

Thus, when the linear scale factor is 1:3 the area factor will be 1 : 9

66 is 13% of 200

F(x)=3x+2, if you are asked to find f(4), what does this mean?

Answers

Answer:

you substitute x for 4

Step-by-step explanation:

so its f(x) and f(4) so you use 4 for x so you would solve f(x)=3(4)+2

Substitute x for 4
For example: f(4)=3(4)+2
So f = 7/2
F = 3.5

Answer:

  1. 2x +2y = 310; x -y = 55

  2. y = 50, x = 105

Step-by-step explanation:

Let the numbers be represented by x and y. Double the numbers would give 2x and 2y. We're told the sum of the doubled numbers is 310, so one equation is ...

  2x + 2y = 310

The difference of the numbers is (x-y). We're told that difference is 55, so the other equation is ...

  x - y = 55

__

We can divide the first equation by 2, and subtract the second.

  1/2(2x +2y) -(x -y) = 1/2(310) -(55)

  2y = 100 . . . . . . . simplify

  y = 50 . . . . . . . . . divide by 2

  x -50 = 55   ⇒   x = 105 . . . . use the second equation to find x

The two numbers are 105 and 55.

A discount store bought two dozen cameras for $14 each.
After the cameras didn't sell for a long period, the store
decreased their selling price to $10.99 per camera. What was the
store's overall loss on the two dozen cameras?

Answers

Answer:

72.24

Step-by-step explanation:

Price for each camera = 14

Number of camera = 2dozen = 12 x 2 = 24

Total cp = 24 x 14 = 336

~~~~~~~~~~~~~~

Price for each camera=  10.99

Number of cams = 24

Total sp = 10.99 x 24 = 263.76

Loss = 336 - 263.76  = 72.24

Un elev a depus la banca suma de 250 lei. Știind ca banca oferă dobânda anuala de 1%,iar stația impozitează dobânda cu 16%,aflati ce suma va avea elevul după un an de depunere.

Answers

Răspuns:

292,50

Explicație pas cu pas:

Dobânda totală% = (1% + 16%) = 17% = 17/100 = 0,17

Suma principală depusă, P = 250

Suma totală, A după 1 an poate fi calculată astfel:

A = P (1 + rt)

Unde ; r = rata dobânzii; t = timp

A = 250 (1 + (0,17 * 1))

A = 250 (1,17)

A = 292,5
