A submarine is only allowed to change its depth be Racing toward the surface in 60 meter stages. If the submarine starts off at
lara31 [8.8K]

Answer:

Depth = 100m

Step-by-step explanation:

Given

Initial Level = 340 m

Number of stages = 4

Difference in each stage = 60 m

Required

Determine the depth of the submarine after 4 stages

First, we have to calculate the total distance moved towards the surface of the sea;

This is calculated as

Total\ Distance = Number\ of\ Stages * Difference\ in\ each\ stage

Total\ Distance = 4 * 60m

Total\ Distance = 240m

This implies that the submarine moved a total distance of 240 metres;

It;'s new depth is calculated as follows;

Depth = Initial\ Depth - Total\ Distance

Depth = 340m - 240m

Depth = 100m

<em>Hence, its new depth after 4 stages of rising is 100m</em>

ERROR ANALYSIS Describe and correct the error in finding the x-intercept.
EastWind [94]

The x-intercept is -6

Step-by-step explanation:

In order to find the x-intercept, we put y = 0 and to find the y-intercept we put x = 0

In the given method, x is put equal to zero instead of y as x-intercept had to be found.

Given equation is:

-2x+3y=12

-2x + 3(0) = 12\\-2x +0 = 12\\-2x = 12

Dividing both sides by -2

\frac{-2x}{-2} = \frac{12}{-2}\\x = -6

The x-intercept is -6

Johnathan can jog 3 2/3 miles in 7/8 hour. Determine his average speed in miles per hour.
kap26 [50]
If you would like to know Johnathan's average speed in miles per hour, you can calculate this using the following steps:

3 2/3 = 11/3 miles ... 7/8 hour
x miles = ? ... 1 hour

11/3 * 1 = 7/8 * x
11/3 = 7/8 * x
x = 11/3 * 8/7 
x = 88/21
x = 4 4/21 miles

The correct result would be 4 4/21 miles per hour.
