Answer 1
Answer:

Answer:

To bring the submarine back to the sea level, it have to move 578 feet upwards

Step-by-step explanation:

Given:

Initially the depth the submarine dives  =  657 feet below sea

The height the submarine moves up =  79 feet

To Find :

Change in its depth required to bring the submarine back to the sea level  = ?

Solution :

In initially the Submarine will be at the depth of  657 feet below sea

when it goes up, the the depth reduces

657 - 79  = 578 feet

Now the submarine will be the depth of  578 feet

Now the submarine have to move  578 feet upwards to reach the sea level

The length of a fence on a scale drawing is 6cm. If the scale is 1cm: 4 m, what is the actual length of the fence.A. 10m
B.18 M
C. 24 M
D. 48 M

Please show work..Not for a cheat but I am struggling understanding proportions and algebra. Thank you

Answers

Answer:  Option 'C' is correct.

Step-by-step explanation:

Since we have given that

Length of a fence on a scale drawing = 6 cm

Scale = 1 cm : 4 m

Let the actual length of the fence be x

Since there is direct variation between the scale and actual.

According to ratio, we will have,

(1)/(4)=(6)/(x)\n\nx=6* 4\n\nx=24\ m

Hence, Option 'C' is correct.
 the answer is C if the scale is 1cm:4m 4x6 is 24
