Your family wants to purchase a new laptop with a 17” widescreen. Since the 17 inches represents the diagonal measurement of the screen (upper corner to lower corner), you want to find out the actual dimensions of the laptop. When you measured the laptop at the store, the height was 10 inches, but you don’t remember the width. Calculate and describe how you could figure out the width of the laptop to the nearest tenth inch.

Answers

Answer 1

Answer:

The size of the screen is an illustration of the Pythagoras theorem.

The width of the laptop is 13.7 inches

The given parameters are:

$\mathbf{Diagonal = 17}$

$\mathbf{Height= 10}$

Using Pythagoras theorem, we have:

$\mathbf{Diagonal^2 = Height^2 + WIdth^2}$

Substitute known values

$\mathbf{17^2 = 10^2 + WIdth^2}$

Collect like terms

$\mathbf{WIdth^2 = 17^2 - 10^2}$

$\mathbf{WIdth^2 = 189}$

Take square roots of both sides

$\mathbf{Width = 13.7}$

Hence, the width of the laptop is 13.7 inches

42gal/7min = 7 gallons per minute

Is 80 a multiple of 4?

Answers

Generally, you can tell if something is a multiple of 4 if it is a multiple of the last two digits, but that works in larger numbers (for example, 2304, you know is a multiple of 4 because the 04 is.)

But, yes it is.

80/4=20

yes here look.....

So please help me here is the question Students from three classes at Hudson valley elementary school are planning a boat trip. On the trip there will be 20 students in each class along with 11 total teachers and 13 total parents. Each boat seats 10 people. How many boats will they need to rent? Explain how you solved the problem

Answers

each class has 20 students

3 classes // 20 x3= 60

60 students + 11 teachers+13 parents = 84 people total

as you cant put half people in boats you round up to 90

meaning you would need 9 boats to have enough space for all of them xx

hope this helped x

They will need to rent 5 boats. 20+11+13=44 and each boat seats 10 people so 44÷10= 4 remainder:4 and you cant keave 4 people out they need another boat.
