Answer: Tim worked on Monday 7:30 and earned $56.25

Step-by-step explanation: Looking at the timecard, Tim entered his job at 8:15 and left at 4:15. If we count the hours as 24h per day, 4:15 is equal 16:15, so, with that:

16:15 - 8:15 = 8h

But, Tim has a half hour lunch, then, on Monday:

8 h - 30 min = 7h30min

In other words, Tim worked 7 hours and 30 minutes on Monday.

For his earnings: He earns $7.50 per hour. As he worked 7h:

1 hour = 7.50

7 hours = 7.(7.50) = 52.50

But, Tim worked 7 hours and 30 minutes. If 1 hour is $7.50, half hour is

\frac{7.5}{2} = 3.75

Finally, in 7 hours and 30 minutes, Tim, roughly, receives:

$52.50 + $3.75 = $56.25

On Monday, Tim received $56.25.

A crewman on a fishing boat was injured and needs to be treated in a hospital right away. You are with a Coast Guard station nea
Alborosie

The helicopter has to leave at 1:30 pm to meet the boat after 2 hours at the meeting point.

<h3>What is Speed ?</h3>

Speed is the distance covered by an object in a given amount of time.

It is measured in km/h or m/h.

According to the data in the question

If the boat goes to the station ,

Speed of the boat = 10mph

it will take 400/10 = 40 hours.

The helicopter has 6600 lbs of fuel.

For the 30 minutes to remove the fisherman and the 1 hour more fuel is needed, that will consume

1.5 *1200 = 1800 lbs of fuel.

the helicopter now has

6600-1800

= 4800 lbs of fuel for flying.

This will give it 4 hours of flying time as

4800 lbs/1200 lbs per hour

it can only fly one way for 2 hours at 150 mph

= 300 miles distance from the station.

The boat is at 400 miles

boat needs to reach the meeting point 300 miles away from the station.

which is 100 miles from where it is now

100/10 = 10 hours

the boat will need 10 hours to go to the meeting point.

To meet the boat , which will take 10 hours the helicopter must start flying after 8 hours as it will also take 2 hrs

So 8 hours from 5:30 am will be 1:30 pm

The helicopter has to leave at 1:30 pm to meet the boat after 2 hours at the meeting point.

A rectangle has a width of 59 centimeters and a perimeter of 238 centimeters. What is the rectangle's length?
Mademuasel [1]

Answer:

60 cm

Step-by-step explanation:

2x the width and 2x the length gives you the perimeter. This can be represented by the equation:

2w + 2L = P

Use the information given in the word problem to fill in the variables.

2(59) + 2L = 238

118 + 2L = 238

move 118 to the other side of the equation.

2L = 238 - 118

2L = 120

move 2 to the other side of the equation.

L = \frac{120}{2}

L = 60

The number of windows on each floor form an arithmetic sequence; 124 windows on the first floor, 116 windows on the second floor
zubka84 [21]

Answer:

Formula is 132 - 8n, and there are 52 windows on 10th floor.

Step-by-step explanation:

difference = 116-124 = -8  ( 8 less windows for every floor you go up)

the first fllor has 124 windows

Formula:

a_{1} = 124

a_{n} = 124 + (-8)(n - 1) = 132 - 8n

10th Floor:

a_{10} = 124 + (-8)(10 - 1) = 124 + (-8)(9) = 124 - 72 = 52  windows
