Jules is aboard a submarine studying marine life. She’s trying to find a family of whales and must time when the submarine descends perfectly to find them. Her submarine is 22 feet below sea level and descends at a constant rate of 12 ft. per minute. The submarine must stay no less than 400 ft. below sea level. Let m = the number of minutes. Write an inequality that can be used to find how long the submarine can descend. Then, write the time the submarine can descend.

Answers

Answer 1

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

Answer 2

Answer:

-22 + -12 >(or equal to) -400.at most 31.5 minutes

Joseph took a taxi from his house to the airport. The taxi company charged a pick-up
fee of $3.10 plus $2 per mile. The total fare was $21.10, not including the tip. Write
and solve an equation which can be used to determine m, the number of miles in the
taxi ride.

Answers

Answer:

2m + 3.10 = 21.10

m = 9

Step-by-step explanation:

First Step

2m + 3.10 =21.10

Subtract 3.10 from both sides

Second Step

2m = 18

Divide 2 from both sides

m = 9

The equation is 2m + 3.10 = 21.10

And, the number of miles in the taxi ride is m = 9.

Here,

Joseph took a taxi from his house to the airport. The taxi company charged a pick-up fee $3.10 plus $2 per mile. The total fare was $21.10.

Now,

The equation is written as,

2m + 3.10 = 21.10

Subtract 3.10 from both sides

2m = 18

Divide 2 from both sides

m = 9

Hence, The equation is 2m + 3.10 = 21.10

And, the number of miles in the taxi ride is m = 9.

Answers

Answer:

RS = 45.9 feet

Step-by-step explanation:

Let the length of RS be represented by x. In the given triangle applying the required trigonometric function, we have;

Cos θ = [tex]\frac{Adjacent}{Hypotenuse}[/tex]

Cos 54 = [tex]\frac{27}{x}[/tex]

⇒ x = [tex]\frac{27}{Cos 54}[/tex]

      = [tex]\frac{27}{0.5878}[/tex]

x = 45.9340

x = 45.9 feet.

The length of RS in the given triangle is 45.9 feet.

Step-by-step explanation:

1st  , notice that our problem is about an eight part whole.  I mean,  the questions are around an object of 8 parts.  so start thinking 1/8 ths

A) asks about P(7)  ... they want to know.. how often the spinner will land on 7. so if it's totally random, 7 will happen just as likely as any of the other numbers so 7 will happen  1/8 th of the time

as a fraction  it's  1/8  as a decimal it's 0.125 and as a percent it's 12.5 %

B) asks about  P(2 or 6 )   [ btw, p here stands for probability ]  

so it's  1/8 + 1/8 =  1/4  or one quarter of the time we would get a 2 or a 6

as a fraction it's  1/4  , as a decimal it's 0.25  and as a percent it's 25%

C)   asks  about P( greater than 4)  or  P( >4)   so that's the whole left side of the circle :0  

as a fraction it's 1/2  as a decimal it's 0.5  and as a percent   it's 50%

D) P( not a 5) or P( ~=5)  so every thing but a 5

as a fraction that's 7/8  as a decimal it's 0.875 and as a percent that 87.5 %

Answers

Answer:

Step-by-step explanation:

6x28=168

To earn atleast $168, Hermes should do babysit for atleast 28 hours.

What is inequality?

Inequality is just like an equation showing relationship between two or more variables but this is expressed in greater than ,less than form.

It defines a range of value of the relationship.

How to form inequality?

We have been given that Hermes earns $6 per hour for babysitting and he wants to earn atleast $168 for a new video game. We have to calculate the minimum number of hours that he should do babysit in order to earn $168.

We know that total revenue will be number of hours* payment of 1 hour.

let the number of hours that he does babysit is x.

The inequality will be :

6x>168

x>168/6

x>28

Hence to earn atleast $168 he should work for atleast 28 hours.
