Answer:

141

Step-by-step explanation:

First, you would round 72.91 to 73 because the number to the right of 7 is greater than or equal to 5, so you would round up. Same goes for 67.526. round both up to 73 and 68 then add. You would get an answer of 141 :)

Answer: 141

Step-by-step explanation: By rounding up to the nearest whole number, that is taking 72.91 -> 73. The reason it is this way is that when a decimal is past 0.5, you round up. If a decmial is below 0.5, then you round down.

In this specific situation, we get the numbers 72.91 and 67.526.

As I explained, the numbers would round up because both numbers decimal values are above 0.5.

So after 72.91 is 73, and after 67.526 is 68.

68 + 73 =

141

hopefully I helped!

(2y+1.6)/0.8=30/2.5<br> Please Help!<br> Solve for Y

galina1969 [7]

y = 4

first note that the right side simplifies to 12, equation can be written

$\frac{2y+1.6}{0.8}$ = 12 ( multiply both sides by 0.8 )

2y + 1.6 = 9.6 ( subtract 1.6 from both sides )

2y = 8 ( divide both sides by 2 )

y = 4

In Exercises 1 and 2, find the equilibrium solutions of the differential equation specified.1) dy/dt = (y + 3)/(1 - y)2) dy/dt =

Aleks [24]

Answer:

1. Equilibrium solution: y= -3

2. Equilibrium solution y= ±1.414

Step-by-step explanation:

Thinking process:

The equilibrium solution can only be derived when $\frac{dy}{dt} = 0$

1. Let's look at the first equation:

$\frac{dy}{dt} = \frac{(y+3)}{(1-y)}$

equating $\frac{dy}{dt} = 0$ to the expression $\frac{(y+3)}{(1-y)}$ gives

y + 3 = 0

y = -3

Therefore, the equilibrium solution occurs at y = -3

2. Let's look at the second solution:

$\frac{dy}{dy} = \frac{(t^{2}- 1) (y^{2}-2) }{y^{2}-4 }$

dividing each side by (t²-1) gives

1/(t²-1) $\frac{dy}{dt}$ = (y²-2)/ (y²-4)

factorizing the right hand side gives:

at equilibrium: $\frac{dy}{dt} = 0$ , then

y² - 2 = 0

solving for y gives y = ±√2

= ±1.414

scoray [572]

Answer:

The difference between the number of drops of water in the larger jug and the number of drops of water in the smaller jug is <u>42,739,999.999999999.</u>

Step-by-step explanation:

Given:

An environmental scientist estimated the number of drops of water in two different jugs. He estimated that the smaller jug contains 8,060,000.000000001 drops of water and the larger jug contains 50,800,000 drops of water.

Now, to find the difference between the number of drops of water in the larger jug and the number of drops of water in the smaller jug.

The smaller jug contains drops of water = 8,060,000.000000001.

The larger jug contains drops of water = 50,800,000.

Now, to get the difference between the number of drops of water we subtract the number of drops of water in the smaller jug from the number of drops of water in the larger jug:

$50,800,000-8,060,000.000000001$

$=42,739,999.999999999$

Therefore, the difference between the number of drops of water in the larger jug and the number of drops of water in the smaller jug is 42,739,999.999999999.
