a) You are given the rate as 7.4m/min,

The equation would become d = 7.4t where d is the total distance and t would be the total number of minutes.

b) d would be a positive number because the diver is ascending, which means he is moving up towards the surface.

c) To find how long it took the diver, replace d with 41.36 ( how deep the diver was) and solve for t:

41.36 = 7.4t

To solve for t, divide both sides by 7.4:

t = 41.36 / 7.4

t = 5.59 minutes ( 5 minutes and 35 seconds)

Which value is equivalent to

Ksenya-84 [330]

Answer:

$\frac{25}{144}$

Step-by-step explanation:

$(\frac{7 * 5 * 2}{7 * 3} )^2 * (\frac{5^0}{2^-3})^3 * 2^{-9}$

Simplified becomes;

$(\frac{10}{3})^2 * 2^3 * \frac{1}{2^9}$

Simplifying further gives; $\frac{25}{144}$

Layla is working two summer jobs, babysitting and tutoring. She can work at most 8 hours altogether between both jobs in a given

ExtremeBDS [4]

Answer:

The inequality equation is $b+t\leq 8$ ,

Step-by-step explanation:

Let the number of hours she work in Babysitting be b.

Also Number of hours she work in tutoring be t.

She can work at most 8 hours altogether between both jobs in a given week.

We need to find the Inequality expression that would represent the possible values for the number of hours babysitting, b and the number of hours tutoring, t.

It can be framed as;

number of hours she work in Babysitting plus Number of hours she work in tutoring should be less than or equal to 8.

Expressing in mathematical form we get;

$b+t\leq 8$

Hence the Inequality is given as $b+t\leq 8$ .
