Why can't irrational numbers be whole numbers

meriva

Irrational numbers cannot be represented by a ratio of two integers.

All whole numbers, however, can. This can be done by placing the number over 1. For example 0/1, 34/1, 173635278/1.

Foram prescritos 500mg de dipirona para uma criança com febre.Na unidade tem disponivel ampola de 1g/2ml.Quantos g vão ser admin

Valentin [98]

De acordo com a disponibilidade da unidade, há apenas a seguinte dosagem: 1g/2mL - ou seja, uma grama de dipirona a cada 2mL

O enunciado está meio mal formulado, pois é dito que foram prescritos 500mg de dipirona e é essa quantidade de farmaco que a criança tem que tomar. Deseja-se saber quantos mL deverao ser administrados.

Fazendo a classica regra de 3, podemos chegar no volume desejado:

(atentar que 500mg = 0,5g)

g mL

1 --------- 2

0,5 --------- X

1 . X = 0,5 . 2

tan∅ = opposite over adjacent

Step-by-step explanation:

Step 1: Define

Angle = 28°

Opposite leg of angle = 8 ft

Adjacent leg of angle = x ft

Step 2: Find x

Substitute: tan28° = 8/x
Multiply x on both sides: xtan28° = 8
Divide tan28° on both sides: x = 8/tan28°
Evaluate: x = 15.0458
Round: x ≈ 15.0 ft

The dockland building in hamburg, germany is built in the shape of a parallelogram. What is the length of the flight of stairs t

Tamiku [17]

Answer:

The length of the flight of stairs is 52 m

Step-by-step explanation:

In parallelograms, opposite sides are equal in length

In the given figure

∵ The building is built in the shape of a parallelogram

∵ The length of the flight of stairs is one side of it

→ We can find it by finding the hypotenuse of the right triangle

whose legs are 47 m and 22 m

∴ The length of it = the length of the hypotenuse of the right Δ

→ By using the Pythagoras Theorem

∵ h = $\sqrt{(leg1)^{2}+(leg2)^{2}}$

∵ leg1 = 47 and leg2 = 22

∴ h = $\sqrt{(47)^{2}+(22)^{2}}$

∴ h = $\sqrt{2209+484}$

∴ h = $\sqrt{2693}$

∴ h = 51.89412298

∵ h represents the length of the flight of stairs

∴ The length of the flight of stairs = 51.89412298 m

→ Round it to the nearest meter

∴ The length of the flight of stairs = 52 m
