Answer: [tex]9.38\times10^{33}[/tex]

Step-by-step explanation:

Given: Molecules in a liter of water = [tex]3.35\cdot10^{25}[/tex]

A certain river discharges about [tex]2.8\cdot10^8[/tex] liter of water every second.

Molecules in river = [tex]3.35\cdot10^{25}\times2.8\cdot10^8[/tex]

[tex]=3.35\cdot2.8\cdot10^{25}\cdot10^8\\\\= 9.38\times10^{25+8}\ \ \ \ [a^m\cdot a^n=a^{m+n}]\\\\= 9.38\times10^{33}[/tex]

Hence, there are [tex]9.38\times10^{33}[/tex] does the molecules in river per second.

Answer:

3/4

You need the LCD which is 4

3 + 1x2/2x2 + 3/4

3 + 2/4 + 3/4

3 + 2+3/4

3+5/4

3 + 1 1/4

20/4 - 4 1/4

20/4 - 4x4+1/4

20/4 - 17/4

5 - 17/4

5x4/4 - 17/4

20/4 - 17/4

3/4

Answer:

2.325

Step-by-step explanation:

i used a calculator ,i think i did it right lol

Answer:

D

Step-by-step explanation:

m=11

Step-by-step explanation:

the top side is 4, so that means the bottom side will also be 4, add them both, you get 8, 30-8 = 22, 22/2 = 11, m=11

Answer:

3

Step-by-step explanation:

2(4m + m) = 30

8m + 2m = 30

10m = 30

Divide by 10 on each side

m = 3

Check:

2 ( (4 x 3) + 3) = 30

2 ( 12 + 3) = 30

24 + 6 = 30

30 = 30

Hope this helps! :)

Answer:

yes

Step-by-step explanation:

it is going by 5s.

Answer:

Yes. This is because if you plot the numbers on a ration table or see the graph points, you can see a pattern: you multiply by 5. The equation to solve this would be y=5x. Another reason why this is proportional is that the graph starts from the origin (0,0) This is the opposite for non-proportional relationships. Hope this helps! :)

Answer:

2x^14

Step-by-step explanation:

Answer:

The value of y=6

Step-by-step explanation:

Given that y varies directly with x

Using the formula

y ∝ x

y=kx

Where k is the constant of proportionality

In order to find 'k' use the given condition

y=8  when  x=20

y=kx

k=y/x  

 = 8/20

 = 2/5

Thus, the equation to find 'y' is

y=2/5x

when x=15 then

y=2/5(15)

 = 6

Thus, the value of y=6

Given:

The exponential function passes through two points (0,4) and (3,32).

To find:

The formula for the exponential function.

Solution:

The general form of an exponential function is

[tex]y=ab^x[/tex]          ...(i)

where, a is initial value and b is growth factor.

The exponential function passes through two points (0,4) and (3,32). It means the function must be satisfy by these points.

Putting x=0 and y=4 in (i), we get

[tex]4=ab^0[/tex]

[tex]4=a(1)[/tex]

[tex]4=a[/tex]

Putting a=4, x=3 and y=32 in (ii), we get

[tex]32=4b^3[/tex]

Divide both sides by 4.

[tex]8=b^3[/tex]

Taking cube root on both sides.

[tex]2=b[/tex]

Putting a=4 and b=2 in (i), we get

[tex]y=4(2)^x[/tex]

Therefore, the required formula for the exponential function is [tex]y=4(2)^x[/tex].

Answer:

6

Step-by-step explanation:

Answer:

y-2=1/8(x+5)

Step-by-step explanation:

1. Perpendicular lines have opposite slopes. To get the new slope, take the slope of the first line and turn it to make it the opposite reciprocal.

Since it's -8, the opposite of it is 1/8.

2. Now, use point slope: y-y1=m(x-x1). Plug in the values of the ordered pair and the slope into the equation.

y-2=1/8(x+8)

And that's your answer

-1/4x+10=7

-1/4x=7-10

-1/4x=-3

-12x=-1

x=1/12

Step-by-step explanation:

m=y²-y¹/x²-x¹

m=(-9)-(-9)/14-8

m=0/6

m=0

Answer: angle 2 is 28

Step-by-step explanation:if angle (1) and (2) are supplementary which equals 180degrees; we know angle one is 152 degrees, so a simple 180-152= 28 degrees; so angle 2 is 28

Answer:

Letter D

Step-by-step explanation:

D KO PO SURE SORRY PO KUNG MALI ✌

Answer:

For part A-Emily would spend $22.70 on 22 feet of wire. For part B- Andy would spend $2.30 for 15 yards of wire.

Step-by-step explanation:

The cost is going down 10 cents by the foot, so getting 22 feet into 264 inches then having 165 into 164 and going up by the ten ending the number in four. Same with the yards in feet then the feet into yards and going down by 10. Hope it helps and makes sense.
