Answer:

5m

Step-by-step explanation:

Calculamos usando la fórmula de la proporción

Sombra / Altura

Deje que la altura de la luz de la calle = x

1,4 m / 1,75 m = 4 m / x

Multiplicar cruzada

1,4 × x = 1,75 × 4

Dividir ambos lados por 1.4

x = 1,75 × 4 / 1,4

x = 5

Por lo tanto, la altura de la farola es de 5 m.

A water dispenser has a capacity of 20,000 milliliters. Use the facts to find how much this is in liters .
laila [671]
Answer:

The water dispenser's capacity in liters is 20liters

Explanation:

Given:

A water dispenser capacity = 20,000milliliters

To find

the capacity of the water dispenser in liters

To determine the capacity in liters, we will convert the capacity in ml to liters using the conversion:

1000ml = 1 liter

let the capacity of the water dispenser in Liters = y

\begin{gathered} 1000ml\text{ = 1 L} \\ 20000ml\text{ = y} \\ cross\text{ multiply:} \\ y(1000)\text{ = 1\lparen20000\rparen} \\ 1000y\text{ = 20000} \end{gathered}\begin{gathered} divide\text{ both sides by 1000:} \\ y\text{ = }\frac{20000}{1000} \\ y\text{ = 20} \end{gathered}

The water dispenser's capacity in liters is 20liters

1/2 (4r+6) what dose (4r+6) mean
Alisiya [41]
Answer: 5

This is because (4r + 6) means you take r and multiply that number by 4.

Because there is no number, r would equal one in this case.

4 • 1 is 4

4 + 6 is 10

This would give us 1/2(10)

Half of 10 is 5.

Therefore, the answer is 5.
