baherus [9]

Answer:

3500.

Step-by-step explanation:

We have been given that Cesar Chavez lead a March with 6,300 people. The ratio of marchers who were not farm-workers to farm-workers is 4:5. We are asked to find the number of marchers, who were farm-workers.

First of all, we will find the ratio of farm-workers to total marchers as:

$\frac{\text{Farm-workers}}{\text{Total marchers}}=\frac{\text{Farm-workers}}{\text{Farm-workers+non-farm-workers}}=\frac{5}{4+5}=\frac{5}{9}$

To find the number of marchers, who were farm-workers, we need to find $\frac{5}{9}$ of whole marchers.

$\text{Number of marchers that were farm-workers}=6300\times \frac{5}{9}$

$\text{Number of marchers that were farm-workers}=700\times \frac{5}{1}$

$\text{Number of marchers that were farm-workers}=3500$

Therefore, 3500 marchers were farmers.

I need help with it pls

Basile [38]

Answer:

Step-by-step explanation:

Step 1: What are the couch's original coordinates?

A: (-4, 2)
N: (-4, 3)
G: (-1, 3)
L: (-1, 4)
E: (-5, 4)
S: (-5, 2)

Step 2: Rotate the couch 90° counterclockwise.

Rule: (x, y) → (-y, x)

A': (-4, 2) → (-2, -4)
N': (-4, 3) → (-3, -4)
G': (-1, 3) → (-3, -1)
L': (-1, 4) → (-4, -1)
E': (-5, 4) → (-4, -5)
S': (-5, 2) → (-2, -5)

Step 3: Now reflect the "new" couch over the y-axis.

Rule: (x, y) → (-x, y)

A'': (-2, -4) → (2, -4)
N'': (-3, -4) → (3, -4)
G'': (-3, -1) → (3, -1)
L'': (-4, -1) → (4, -1)
E'': (-4, -5) → (4, -5)
S'': (-2, -5) → (2, -5)

Step 4: Finally translate the new new" couch right 1 unit and up 5 units.

Rule: (x + 1, y + 5)

A''': (2, -4) → (2 + 1, -4 + 5) → (3, 1)
N''': (3, -4) → (3 + 1, -4 + 5) → (4, 1)
G''': (3, -1) → (3 + 1, -1 + 5) → (4, 4)
L''': (4, -1) → (4 + 1, -1 + 5) → (5, 4)
E''': (4, -5) → (4 + 1, -5 + 5) → (5, 0)
S''': (2, -5) → (2 + 1, -5 + 5) → (3, 0)

Step 5: Use the distance formula to show that the length of EG is the same as the length of E'''G'''.

EG: (-5, 4)(-1, 3)
E'''G''': (5, 0)(4, 4)

Distance between E(-5, 4) and G(-1, 3)

x₁ = -5
x₂ = -1
y₁ = 4
y₂ = 3

$\large \textsf {d = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$}\\\\\large \textsf {d = $\sqrt{(-1-(-5))^2+(3-4)^2}$}\\\\\large \textsf {d = $\sqrt{(-1+5)^2+(3-4)^2}$}\\\\\large \textsf {d = $\sqrt{4^2+(-1)^2}$}\\\\\ \large \textsf {d = $\sqrt{16+1}$}\\\\\large \textsf {d = $\sqrt{17}$}\\\\\large \textsf {d = ${4.12}$}$

Distance between E'''(5, 0) and G'''(4, 4)

x₁ = 5
x₂ = 4
y₁ = 0
y₂ = 4

$\large \textsf {d = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$}\\\\\large \textsf {d = $\sqrt{(4-5)^2+(4-0)^2}$}\\\\\large \textsf {d = $\sqrt{(-1)^2+4^2}$}\\\\\large \textsf {d = $\sqrt{1+16}$}\\\\\ \large \textsf {d = $\sqrt{17}$}\\\\ \large \textsf {d = ${4.12}$}$

This means that the length of EG is the same as the length of E'''G'''.

Hope this helps!

When is a rhombus a rectangle?

Alinara [238K]

Check the picture below.

a rhombus is a quadrilateral with all equal sides.

now, the sides do not have to be slanted, but they must be equal, IF it happens that all sides meet at right-angles, then the rhombus is a "rectangle", due to its right-angleness, incidentally enough, since all sides are equal, if that ever happens, it also becomes a square.
