Answer:

The altitude is changing at a speed of 200 √3 km/hr

Step-by-step explanation:

Here, we want to know how far the altitude of the plane is changing

we are told that the airplane makes an angle of 60 degrees with the ground

So therefore , the rate of change of its altitude will be ;

sin 60 = x/ 400

x = 400 sin 60

x = 400 * √3/2

x = 200 √3 km/hr

Round to the nearest cent.<br> 5. $406.439
boyakko [2]

Answer:

406.4

Step-by-step explanation:

When rounding you only look at the number you're rounding and the one before it. In this case it would be the 4 and 3 after the decimal since we're rounding to the nearest cent. If the numbers before the one you're rounding are 0-4 then you leave the number the same. If the numbers are between 5-9 then you add one to the number. Since the number before 4 is between 0-4 you leave it as 4. But if it was between 5-9 then you'd change the 4 to 5.

Ishaan is 727272 years old and William is 444 years old. How many years will it take until Ishaan is only 555 times as old as Wi
Sati [7]

Answer:

It will take 13 years to Ishaan age will be 5 times William age.

Step-by-step explanation:

Given : Ishaan is 72 years old and William is 4 years old.

To find : How many years will it take until Ishaan is only 5 times as old as William?

Solution :

Let x be years since today.

According to question,

Ishaan's age is I=72+x

William's age is W=4+x

Now, We want the time for Ishaan age will be 5 times William's age:

i.e. I=5W

72+x=5(4+x)

72+x=20+5x

72-20=5x-x

52=4x

x=13

It will take 13 years to Ishaan age will be 5 times William age.

By this time William will be 17 years old and Ishaan will be 85 years old.

Why do 4500 divided by 90 and 450 divided by 9 have the same answers
vladimir2022 [97]

Answer:

The numbers are closely related to each other, 4500 being 450 multiplied by 10, and 90 being 9 multiplied by 10 as well. Therefore, they equal the same amount.

Step-by-step explanation:

I don't know if that made sense but I hope it helps! Just know that 4500x90 is only one place value over 450x9.
