Let’s first find the rate that she types at in wok.
128/3 = 42+2/3 words per minute.
Now divide 576 by the rate.
576/42.666= 13.5 minutes

Uma balconista vendeu 70 centímetros de tecido a um freguês. Essa balconista preencheu corretamente a nota fiscal, escrevendo:
Evgesh-ka [11]

Answer:

Step-by-step explanation:

A clerk sold 70 centimeters of fabric to a customer. This clerk correctly filled out the invoice, writing:

1 point

a) 0.07 m

b) 0.070 m

c) 0.070 cm

d) 0.70 m

The clerk sold 70cm of fabrics

So, she want to filled the invoice but it length of fabrics sold must be in metre.

From metric units

100cm = 1m

Then,

70 cm = x

100cm = 1m

Cross multiply

70 cm × 1m = x × 100cm

Divide both side by 100cm

Then,

x = 70 cm × 1 m / 100cm

cm cancel out

x = 70 × 1m / 100

x = 70m / 100

x = 0.7m.

So, the correct answer is D.

To Portuguese

O funcionário vendeu 70cm de tecidos

Então, ela deseja preencher a fatura, mas o comprimento dos tecidos vendidos deve estar em metros.

De unidades métricas

100cm = 1m

Então,

70 cm = x

100cm = 1m

Multiplicação cruzada

70 cm × 1 m = x × 100 cm

Divida os dois lados por 100cm

Então,

x = 70 cm × 1 m / 100 cm

cm cancelar

x = 70 × 1m / 100

x = 70m / 100

x = 0,7 m.

Então, a resposta correta é D.

J has coordinates (-2,8) R has coordinates (-7,-3) find the coordinates of point A that partition (JR) in the ratio 5:2 and sket
kolbaska11 [484]

J Coordinates: (-2,8)

R Coordinates: (-7,-3)

A cuts JR in the ratio of 5:2

We have to find out the coordinates for A. Let coordinates of A be (x,y)

The section formula helps us determine a point (x,y) that divides the line joining two points (x1,y1) and (x2,y2) in the ratio of m:n

x1, y1 represents the point which is more on the left side of the x axis, while x2,y2 represents the point which is more on the right side of the x axis

So here x1 = -7, y1 = -3, x2 = -2, y2 = 8, m = 5, n = 2

As per section formula, x = (mx₂ + nx₁) / (m + n), and y = (my ₂ + ny₁) / (m + n))

⇒ x = ((5*-2) + (2*-7)) / (7)

⇒ x = (-10+ (-14)) / (7)

⇒ x = -24 / 7

⇒ x = -3.43

and y = ((5*8) + (2*-3)) / (7)

⇒ y = (40 - 6) / 7

⇒ y = 4.86

So coordinates of A are (-3.43,4.86)

Please see the attached image for seeing the points and line on chart.
