Viktor [21]

Answer:

32.33 <= m

Step-by-step explanation:

Since we are dealing with below sea level our initial starting point and max level will both be negative values, while our descending rate will also be negative because we are going down. Using the values provided we can create the following inequality...

-400 <= -12m - 12

Now we can solve the inequality to find the max number of minutes that the submarine can descend.

-400 <= -12m - 12   ... add 12 on both sides

-388 <= -12m   ... divide both sides by -12

32.33 <= m

Put this equation into slope intercept -2×+3y=9
siniylev [52]

y = \frac{2}{3} x + 3

The equation of a line in slope-intercept form is

y = mx + c ( m is the slope and c the y-intercept )

rearrange - 2x + 3y = 9 into this form

add 2x to both sides

3y = 2x + 9 ( divide all terms by 3 )

y = \frac{2}{3} x + 3 ← in slope-intercept form

jolli1 [7]

Answer:

6.21 times more

Step-by-step explanation:

Assuming 2.04 x 10^11 was only a typo

you would need to first equal the powers of 10

so 20.4 x 10^10 and 3.28 x 10^10

now that they have the same powers

\frac{20.4 * 10^{10}}{3.28 * 10^{10}}  = \frac{20.4}{3.28} = 6.219512...

if it's asking for how many times i would approximate it to 6.21 times more

How you tell 7/10 is greater than 1/2 without using a model
Lesechka [4]
If you can make the denominators the same so 2 can become 10 by mulitiplying by 5 and 1x5 is 5 so 5/10 is less than 7/10
