The volume of a rectangular box with a square base remains constant at 500 cm3 as the area of the base increases at a rate of 6

Andre45 [30]

Answer:

the rate at which the height of the box is decreasing is -0.0593 cm/s

Step-by-step explanation:

Given the data in the question;

Constant Volume of a rectangular box with a square base = 500 cm³

area of the base increases at a rate of 6 cm²/sec

so change in the area of the base with respect to time dA/dt = 6 cm²/sec

each side of the base is 15 cm long

so Area of the base = 15 cm × 15 cm = 225 cm²

the rate at which the height of the box is decreasing = ?

Now,

V = Ah

dv/dt = 0 ⇒ Adh/dt + hdA/DT = 0

⇒ dh/dt = -hdA/dt / A

we substitute

dh/dt = [ -( 500 / 225 ) × 6 ] / 225

dh/dt = [ -(2.22222 × 6) ] / 225

dh/dt = [ -13.3333 ] / 225

dh/dt = -0.0593 cm/s

Therefore, the rate at which the height of the box is decreasing is -0.0593 cm/s

Are the equations correct? And how do you solve this completely?

irina [24]

Your equations are right. just use the substitution method to solve. substitute y because both have that on one side

it'll look like 40x+30=30x+60.
then just get x in one side. I showed my owrk in the photo

What is 247,039 rounded to the nearest thousand

DerKrebs [107]

Answer:
247,000

Explanation:
To round a number to the nearest thousand, we check the digit in the hundreds position:
1- If the digit is less than 5, then we round down. This means that we simply convert all digits after the thousands to zero and that's it
2- If the digit is equal to or more than 5, then we round up. This means that we add one to the thousands digit and then convert all digits after the thousands to zero.

In the given number 247039, the number in the hundreds position is 0. This means that we will round down

Therefore, 246039 rounded to the nearest thousand would simply give 247000

Hope this helps :)

Roland bought a dresser for k dollars. After restoring it, he sold it for 3.1k dollars. Which is another way to describe the cha

xxMikexx [17]

Answer: 210 percent increase

Step-by-step explanation: So w know the starting value is k so we can replace it with 1 dollar

now we know he bought the dresser for 1 dollar and sold it for 3.10 dollars

First we have to subtract the starting value 3.1 - the original value

3.1 - 1 = 2.1

then we have to divide that number by the starting value

2.1 divided by 1 = 2.1

Lastly multiply times 100 to get the percent increase

2.1 x 100 = 210 % increase

hope this helps mark me brainliest if it helped
