C = d*pi
78.5 = 3.14 d
d = 78.5/3.14
d = 25 feet

Circumference=Diameter×pi
78.5=d(3.14)
78.5=d3.14
78.5/3.14=d3.14/3.14
25=d
The diameter of the circle is 25 feet

liberstina [14]

Answer:

<h2><u>The amount paid to an employee was </u><u>162</u></h2>

Step-by-step explanation:

<h2><u>The expression 12h + 30w Identifies the amount paid to an employee.</u></h2><h2><u>Let h represent hours and let w represent the total amount of g-wagons sold. </u></h2><h2><u>Since the question explains that an employee works 6 hours and sells 3 wagons, put h as h = 6 and w as w = 3. We would end up getting this equation. 12h + 30w = 12(6) + 30(3).</u></h2><h2><u>Now all you need to do is solve it.</u></h2><h2><u>left side = 72</u></h2><h2><u>right side = 90</u></h2><h2><u>72 + 90 =</u><u> 162</u></h2>

Five bells begin to ring together and they ring at intervals of 3, 6, 10, 12 and 15 seconds, respectively. How many times will t
Evgen [1.6K]

Answer:

60 times will they ring together at the same second in one hour excluding the one at the end.

Step-by-step explanation:

Given : Five bells begin to ring together and they ring at intervals of 3, 6, 10, 12 and 15 seconds, respectively.

To find : How many times will they ring together at the same second in one hour excluding the one at the end?

Solution :

First we find the LCM of 3, 6, 10, 12 and 15.

2 | 3  6  10  12  15

2 | 3  3   5   6  15

3 | 3  3   5   3  15

5 | 1    1  5   1    5

  | 1    1   1   1     1

LCM(3, 6, 10, 12,15)=2\times 2\times 3\times 5

LCM(3, 6, 10, 12,15)=60

So, the bells will ring together after every 60 seconds i.e. 1 minutes.

i.e. in 1 minute they rand together 1 time.

We know, 1 hour = 60 minutes

So, in 60 minute they rang together 60 times.

Therefore, 60 times will they ring together at the same second in one hour excluding the one at the end.

Find the two values of k for which y(x)=ekx is a solution of the differential equation
Travka [436]

Answer:

The 2 values of k are 3 and 6.

Step-by-step explanation:

If the given function  of y is a solution of the differential equation then it shall be able to satisfy it

Thus we have

y''-9y'+18y=0

Putiing y=e^{kx} in the above differential euation we get

\frac{d^2e^{kx}}{dx^2}-9\frac{de^{kx}}{dx}+18\cdot e^{kx}=0\\\\k^{2}e^{kx}-9k\cdot e^{kx}+18\cdot e^{kx}=0\\\\k^2-9k+18=0

Solving the above uadratic euation with the standard formula we get

k=\frac{-(-9)\pm \sqrt{(-9)^2-4\times 1\times 18} }{2}\\\\k_1=6\\\\k_2=3
