Answer:

Step-by-step explanation:

a)

2.64÷3.3 ( said 2.64 divided by 3.3)

3.3√2.64 ( yes I know it's not the division sign but it's as close as we can get)

2.64 / 3.3

All three representations are the same. each say divide 2.64 by 3.3. If you're thinking that last one looks more like a fraction, you're right, but.. that's also what that means. I'm showing these different ways to express the idea of division b/c it's part of what is involved with showing the work and understanding it.

so, to do the above let's move the decimal point to the right .. and do we want to move it one or two places. :? one because of 3.3 or two , because of 2.64, well we want to move it so we don't have to think about it in the problem... so move it the biggest amount that you need to, get the the decimil out of both numbers.. since the 2.64 needs two moves to the right of the decimal... use 100 times to move it 2 places, If you needed 3 then use 1000, 4 , 10,000 ect ect... see the pattern?

so

100(3.3 √ 2.64 )

move the decimal point in both 2 places right

330.0 √ 264.0

I put the extra zeros in, just so you can see the decimal easy. The zeros to the right of the decimal make no difference here.

now I'll know to put the number that I use to divde with above the zero, of 264.0 .. and i'll think about how many times 3 goes into 26 ,without going over. 3*8 = 24 so I want an 8

↓ ← ← ← 0.8

330.0 √ 264.0 ( multiply 8 * 330 = 2640 )

↓ → -264 .0 ( subtract 2640 from the number above )

0

you are done with that one, since there is zero left over and 0.8 is the answer

b)

0.324 ÷ 0.27

0.27 √ 0.324

0324 / 0.27

1000( 0.27 √ 0.324)

270 √ 324.0

↓ ← ← 1.2

270 √ 324.0

↓→ - 270 ( multiply by the 1 )

↓ = 54

↓→ - 540 (multiply by the 2 )

0

since there is zero left over you are done. The answer is 1.2

C)

0.32 ÷ 0.16

0.16 √ 0.32

100(0.32 / 0.16)

↓ ← 2

16 √32

↓→ -32 ( multiply 16 * 2 = 32 )

0

zero left over you are done. the answer is 2 :)

d)

16.92 ÷ 9.4

9.4 √ 16.92

100(16.92 / 9.4)

↓ ← ← 1.8

940 √1692.0

↓→→ - 940 (multiply by 1 )

↓ 7520

↓→ - 7520 (multiply by 8 )

0

since there is zero left you are done, The answer is 1.8

that was a lot, really nobody has talked or told you how to do this before?

where is your teacher? :/

A valve in a full 6000 gallon water tank is slowly opening. Water flows out of the tank through the valve. The flow rate in gall

Wittaler [7]

The volume of the gallon is 6000 gallon
the rate of water flow per min is f(t)=300t^2
a] amount of water that flowed in the first 7 minutes=7/60 hours will be:
f(7)=300(7/60)^2
solving the above we get
f(7)=7/12 gallons

b] The time taken for the tank to be empty will be as follows:
amount of water that will flow out for the tank to be empty will be 6000 gallons
thus,
6000=300t^2
this can be simplified to
20=t^2
t^2-20=0
solving this we get:
t=-2√5 or 2√5
the time taken for the tank to be empty will be t=2√5 hours=5.4721 hours

3. What are some of the goods that were in high demand and traded throughout the Afro-Eurasian

maxonik [38]

Step-by-step explanation:

Afro Eurasian network of trade basically encompassed all the major routes of trade before the discovery of Americas and thus meant that the tarde of many things was being done in different parts of it and from different parts of it.

The African coasts were rich in minerals and gold so it was traded from there while India and China were rich in silk, cotton, grain along with the very valuable salt which was also a commodity of the eastern and south eastern part of Asia.

The European trade route largely contributed to metals and non metals required for construction as well as other elements.

If f(x) = 3 – 2x and 1/x+5, what is the value of (f/g)(8)? –169 –1 13 104

Basile [38]

I'm assuming that this is the complete question.
If f(x) = 3 – 2x and g(x)=1/(x+5), what is the value of (f/g)(8)? a) –169 b) –1 c) 13 d) 104
x = 8
f(x) = 3 -2xf(8) = 3 - 2(8) = 3 - 16 = -13
g(x) = 1/(x+5)g(8) = 1/(8+5) = 1/13
(f/g)(8)f(8)/g(8) = -13/ (1/13) = -13 * 13 = -169 Choice A :)
