Which equations show inverse operations of each other? Choose exactly two answers that are correct. 16×1/4 =4 1/4 ÷4 =116

qaws [65]

Answer:

6 × 1/4 = 4

4 × 1/4 = 1

4 ÷ 1/4 = 16

All three of these are correct

Step-by-step explanation:

16 × 1/4 = 4

16/4 = 4

4 = 4

1/4 ÷ 4 = 116

1/4 × 1/4 = 116

1/16 ≠ 116

4 x 1/4 = 1

4/4 = 1

1 = 1

4 ÷ 1/4 = 16

4 × 4 = 16

16 = 16

Two towns that are 31.5 km apart are 3 cm apart on a map. what is the scale of the map?

VLD [36.1K]

Answer:

1 cm : 10.5 km

Step-by-step explanation:

We are given that two towns are 31.5 km in real and are 3 cm apart on a map and we are to find the scale of the map.

For this, we can use the ratio method.

$\frac { 3 cm } { 1 c m } = \frac { 3 1 . 5 k m } { x }$

$x = \frac { 3 1 . 5 \times 1 } { 3 }$

$x = 1 0 . 5$

Therefore, the scale of the map would be 1 cm : 10.5 km.
