Answer:

The rate of exchange is 8%

Step-by-step explanation:

Given as :

Shelley delivered 12 newspaper after  20 min

And She delivered 36 papers after 60 min

Let the exchange rate = R %

So,

     Final value = Initial value ×  ( 1 + \frac{Rate}{100} )

Or, 36 × 60 =  12 × 20 ×  ( 1 + \frac{Rate}{100} )

Or,  2160  = 240 ×  ( 1 + \frac{Rate}{100} )

Or,   \frac{2160}{240} =  ( 1 + \frac{Rate}{100} )

Or,   9   =  ( 1 + \frac{Rate}{100} )

∴     \frac{Rate}{100} = 9 -1 = 8

Or , Rate = 8%

Hence The rate of exchange is 8%   Answer

PLEASE I REALLY NEED YOUR HELP!
Ivenika [448]

Answer:

x = 28

m∠ACD = 68°

Step-by-step explanation:

∠BAE ≅∠DAC because they are vertical angles

∠ACD = 180 - 124 = 56°

to find 'x':   56 + 2x + (180 - 4x) = 180

236 - 2x = 180

-2x = -56

x = 28

m∠ACD = 180 - 4(28)  =  180 - 112  =  68°

PLEASE HELP!!!!!! 100 POINTS!!!!!!!!
FrozenT [24]

Answer:

Answers are below

Step-by-step explanation:

Hour 0                 1 bacterium

Hour 1                  3 bacterium

Hour 2                 9 bacterium

Hour 3               27 bacterium

Hour 4                81 bacterium

Hour 5            243 bacterium

Hour 6            729 bacterium

After 24 hours, the number of the bacterium will reach 282,429,536,481.

B)  This table represents exponential growth because of the number of bacterium always being multiplied by 3.

C)  The reason that any number to the zero power is one is that any number to the zero power is just the product of no numbers at all, which is the multiplicative identity, 1.

D)  Y = 1 + 3 to the power of x

E)  The rule would change by having all of the numbers multiplied by 100 since there is 100 bacterium at Hour 0.

Hey there,

Your question states: You have a 332 feet fencing to enclose a rectangular region. What is the maximum area.

Your correct answer would be 6,889.

Reason/explanation: 

The formula that we would use is P = 2l+2w

f(x)=ax^{2} +b*x+c

L=166=-W\\  L=83
_____________________________________________________________

So by this, now that we know that L=83

We do . . . 83 × 83. . . 

And you final answer would be Option A.) 6,889

Hope this helps you!

Answer:

slope = 2

Step-by-step explanation:

Pick two points to find the slope. (1, 2) and (3, 3)

From the left (1, 2) to (3, 3), it goes up 2 units and to the right 1 unit.

We can plug this into the slope equation which is rise/run

2/1 = 2 = slope
