The answer is 2,925
to get the answer: 26*112=2912 .5 equals half an hour so half the pages
so you add 2912 + 13= 2925

Answer:

19/100 which is already simplified( it can't be simplified)

How I got the answer: subtract 81 from 100 and you'll get 19.

Put 19 over 100 (19/100) and there's the answer.

devlian [24]

Answer:

The predicted time, in minutes, that it took to gather the items if the order has 22 items is 63.8905 minutes

Step-by-step explanation:

Regression Output :

Predictor Coefficient

Constant 3.0979

Square root of items 2.7633

R.sq.- 96.7%

So, with this data the regression equation is,

$\hat{y}=3.0979+2.7633x$

Now we are supposed to find the predicted time, in minutes, that it took to gather the items if the order has 22 items

Substitute x =22 in equation

$\hat{y}=3.0979+2.7633(22)$

$\hat{y}=63.8905$

Hence the predicted time, in minutes, that it took to gather the items if the order has 22 items is 63.8905 minutes

3 times 5 times 2.5 = $37.5

3 x 5 =15

15 x 2.5 =37.5

37.5 x 2 = 75 for both of them

I don't know if this is right or not, but that's how I would solve it!

Un bosque de 2 km2 está formado por hayas y pinos. Las hayas ocupan 380.000 m2 ¿Cuántos metros cuadrados ocupan los pinos?

Ivanshal [37]

Answer:

Los pinos ocupan $\\ 1620000m^{2}$ o 1 millón seiscientos veinte mil metros cuadrados.

Step-by-step explanation:

Una manera de resolver este problema es la siguiente:

$\\ 1km^{2} = 1km * 1km = 1000m * 1000m = 1000000m^{2}$

$\\ 2km^{2} = 2km * 1km = 2000m * 1000m = 2000000m^{2} = 2 * 10^{6}m^{2}$

En palabras, $\\ 2km^{2} = 2000000m^{2}$ , o dos kilómetros cuadrados son iguales a 2 millones de metros cuadrados.

Sabemos que:

Estos $\\ 2km^{2} = 2000000m^{2}$ de bosque lo ocupan hayas y pinos, y, adicionalmente,
Las hayas ocupan $\\ 380000m^{2}$ .

De esta manera, la parte que ocupan los pinos es el total del bosque menos el área ocupada por las hayas. Por lo tanto, el área ocupada por los pinos es:

$\\ 2000000m^{2} - 380000m^{2}$

$\\ 1620000m^{2}$

¿Cuántos metros cuadrados ocupan los pinos?

Los pinos ocupan, entonces, $\\ 1620000m^{2}$ o 1 millón seiscientos veinte mil metros cuadrados.
