Clare knows that Priya has a bunch of nickels and dimes in her pocket and that the total amount is $1.25. Write an equation that
Mrrafil [7]

Answer:

The equation that describes the relationship between the number of dimes and the number of nickels in Priya's pocket. is;

0.05n+0.10d=1.25

Explanation:

Let n and d represent the number of nickels and dimes in her pocket;

We know that;

1 nickel is 5 cents = 0.05 dollar

1 dime is 10 cents = 0.10 dollar

Also;

n nickels = n times 0.05 dollars

0.05n

d dimes = d times 0.10 dollar

0.10d

The total is given as;

the total amount is $1.25.

So, we have the equation as;

0.05n+0.10d=1.25

Therefore, the equation that describes the relationship between the number of dimes and the number of nickels in Priya's pocket. is;

0.05n+0.10d=1.25

The number y of hits a new website receives each month can be modeled by y = 4070ekt, where t represents the number of months th
makvit [3.9K]

Answer:

<u><em>k = 0.2645</em></u>

Step-by-step explanation:

Given model:

y = 4070 e^{kt}

y = no. of hits website received = 9000 (in 3rd month)

t= no. of months website has been operational = 3

put in the above equation:

9000 = 4070  e^{3k}

\frac{9000}{4070} = e^{3k}

\frac{900}{407}=e^{3k}

<u><em>Taking natural logarithm on both sides, we get:</em></u>

ln\frac{900}{407}=ln(e^{3k})

ln\frac{900}{407}= 3k ln<em>e</em>

ln<em>e</em>=1

ln \frac{900}{407}= 3k

or k = \frac{1}{3}ln\frac{900}{(407)}

k =\frac{1}{3}(0.7936)

<em>k = 0.2645</em>

I need help with this question please
Mice21 [21]

Answer:

210 mph

Step-by-step explanation:

speed of jet = x

headwind: speed = x - 27

time taken = 1134.6/(x - 27)

tailwind: speed = x + 27

time taken = 1469.4/(x + 27)

same amount of time:

1134.6/(x - 27) = 1469.4/(x + 27)

Cross multiply,

1134.6(x + 27) = 1469.4(x - 27)

1134.6x + 30634.2 = 1469.4x - 39673.8

334.8x = 70308

x = 210 mph
