Answer:

17.69 miles

Step-by-step explanation:

We are given that Brian is riding his bike with a speed of 12.2 miles per hour . We have to evaluate the distance traveled if he rides his bike for 1.45 hours.

We know that the formula for distance is given as

Distance = speed * time

Distance = 12.2 * 1.45

Distance = 17.69

Hence Brian travels 17.69 miles.

Answer:

First, multiply the numbers. Then count the number of decimal places in each factor. Place the decimal in the product so the product has the same number of decimal places as both factors combined.

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.

4x - 3y = -28 x + 5y = 39 cant seem to be able to figure the answer for this

Rus_ich [418]

value of x = -1 and value of y=8

Step-by-step explanation:

We need to solve the system of equations:

$4x - 3y = -28\,\,\,(1)\\x + 5y = 39\,\,\,(2)$

Multiply eq(2) with 4 and subtract with eq(1)

$4x-3y=-28\\4x+20y=156\\-\,\,\,-\,\,\,\,\,\,\,\,\,\,\,\,\,\,-\\--------\\-23y=-184\\y=\frac{-184}{-23}\\y=8$

So, value of y=8

Now, finding value of x by putting value of y in equation 2

$x+5y=39\\x+5(8)=39\\x+40=39\\x=39-40\\x=-1$

So, value of x = -1

value of x = -1 and value of y=8

HELP QUICK!!!

sattari [20]

Answer:

Step-by-step explanation:

let the length of shortest side be x

and length of second side be 2x

and third side be x+17

given , perimeter = 173 feet

therefore , x+2x+x+17 =173

4x =173-17

4x =156

x = 156/4

x = 39

therefore ,

length of :

shortest side = 39 feet

second side =78 feet

third side =56 feet

hope it helps.. please mark me as the brainliest...
