Answer:

52 cm^2

Step-by-step explanation:

To find the rectangular area on the bottom you multiply 3 by 5 = 15 cm^2.

To find the triangular area on the sides you multiply 4 by 3 = 12 cm^2 then divide by 2 = 6 cm^2, but since there are 2 of them you multiply by 2 again and end up with a surface area of 12 cm^2.

To find the square area on the top you multiply 5 by 5 = 25 cm^2.

So the total surface area is 25+15+12 = 52 cm^2.

Note: cm^2 represents cm squared

Se obtuvo $ 448 de ganancia por la venta de donas.

Se obtuvo $ 280 de ganancia por la venta de bolillos.

Step-by-step explanation:

1) ¿Cuanta ganancia se obtuvo en la venta de donas?

La ganancia es el producto del porcentaje producido de donas, expresado como razón, el precio unitario de la dona y el total producido de panes. Es decir:

$C = \frac{40\,donas}{100\,panes}\times (140\,panes)\times \left(8\,\frac{USD}{dona} \right)$

$C = 448\,USD$

Se obtuvo $ 448 de ganancia por la venta de donas.

2) ¿Cuanta ganancia se obtuvo en la venta de bolillos?

La ganancia es el producto del porcentaje producido de bolillos, expresado como razón, el precio unitario del bolillo y el total producido de panes. Es decir:

$C = \frac{25\,bolillos}{100\,panes}\times (140\,panes)\times \left(8\,\frac{USD}{bolillo}\right)$

$C = 280\,USD$

Se obtuvo $ 280 de ganancia por la venta de bolillos.

Helo me please please

drek231 [11]

i) Area = length x width

=250 x 100

= 25000 cm2

ii) it is a square so the sides are equal

Area = 10 x 10

= 100cm2

iii) 25000/100

250 tiles will be needed

Iv) one tile is 4.75 dollars

Total tiles are 250

Cost for tiling

=250 x 4.75

=1187.5

Hope this helps

M(x) = x² - 4x + 3
m(x) = x² - x - 3x + 3
m(x) = x(x - 1) - 3(x - 1)
m(x) = (x - 3)(x - 1)

(x - 3)(x - 1) = 0
x - 3 = 0 ∧ x - 1 = 0
x = 3 ∧ x = 1

or

m(x) = x² - 4x + 3
Δ = (-4)² - 4 · 1 · 3
Δ = 16 - 12 = 4
√Δ = √4
√Δ = 2

x = (4 - 2)/2 ∧ x = (4 + 2)/2
x = 2/2 ∧ x = 6/2
x = 1 ∧ x = 3
