Write these lengths in order of size, starting with the smallest. 0.043 km 433cm 4340mm 4.3m
Ahat [919]

The order of length measurement starting with the smallest is 4.3 m, 433 cm, 4340 mm, and 0.043 km.

To compare the given measurements of length, they should have similar units. In this case, we can convert each length measurement to meter. The following conversion of different units to meter is listed below:

  • 1 km = 1000 m
  • 1 cm = 0.01 m or 100 cm = 1 m
  • 1 mm = 0.001 m or 1000 mm = 1 m

Conversion of units to m:

  • 0.043 km * (1000 m/km)= 43 m
  • 433 cm * (0.01 m/cm) = 4.33 m
  • 4340 mm * (0.001 m/mm)= 4.34 m
  • 4.3 m

Lengths in order of size starting with the smallest:

  1. 4..3 m
  2. 433 cm or 4.33 m
  3. 4340 mm or 4.34 m
  4. 0.043 km or 43 m

The coordinates of point A on a grid are (−3, −2). Point A is reflected across the y-axis to obtain point B. The coordinates of
Lina20 [59]

Answer:

The coordinates of point B are  (3,-2)

Step-by-step explanation:

we know that

The rule of the reflection of a point across the y-axis is given by

(x,y) -----> (-x,y)

so

Applying this rule to the point A(-3,-2)

A(-3,-2) --------> B(3,-2)

therefore

The coordinates of point B are  (3,-2)

Graph the line passing through (−2,5) whose slope is m=1/5
Nonamiya [84]

Hello there! :)

Given:

x-coordinate of point = -2

y-coordinate of point = 5

Slope, or "m" = 1/5

Substitute in these values into slope-intercept formula (y = mx+b)

5 = 1/5(-2) + b

5 = -2/5 + b

25/5 = -2/5 + b

27/5 = b

Rewrite the equation:

y = 1/5x + 27/5

Graph the equation using a graphing utility:
