A newly constructed fish pond contains 1000 liters of water. Unfortunately, the pond has been contaminated with 5 kg of a toxic

chemical during the construction process. The pond's filtering system removes water from the pond at a rate of 200 liters/minute, removes 50% of the chemical, and returns the same volume of (the now somewhat less contaminated) water to the pond.
Write a differential equation for the time (measured in minutes) evolution of:
a) The total mass (in kilograms) of the chemical in the pond.
b) The concentration (in kg/liter) of the chemical in the pond.
c) The concentration (in grams/liter) of the chemical in the pond.
d) The concentration (in grams/liter) of the chemical in the pond, but with time measured in hours.

Round 9118 to the nearest ten
gavmur [86]

(8)=ones place

(1)0=tens place

(1)00=hundreds place

(9)000=thousands place

The "1" beside the 8, is the tenths spot so you would round that part of the number.

Therefore the answer would be:

9120

Can someone please help me! Big ideas 8.4 number 16
8_murik_8 [283]
<h3>Answer:   24.5 </h3>

============================================================

Explanation:

It might help to draw it out. See the diagram below.

The base is JK which is 7 units long. I'm picking this as the base because this segment is completely horizontal.

Notice how the base JK spans from x = -3 to x = 4, which we can use subtraction and absolute value to get |J-K| = |-3-4| = 7.

The height is always perpendicular to the base. If the base is JK = 7, then the height is the vertical distance from K (or J) to L. This vertical distance is also 7 units. Subtract the y coordinates and apply absolute value. The base and height aren't always the same number.

Now we can find the area of the triangle

area = base*height/2

area = 7*7/2

area = 49/2

area = 24.5 square units
