Answer:

r = 9 ft
h = 5 ft
V = 1272.35 ft³
L = 282.743 ft²
T = 254.469 ft²
B = 254.469 ft²
A = 791.681 ft²

Agenda:

r = radius
h = height
V = volume
L = lateral surface area
T = top surface area
B = base surface area
A = total surface area
π = pi = 3.14159
<span>√ = square root

Dr. Irvine saw 130 patients in one week. The ratio of kids to adults that he saw is 3 to 7. If k represents the number of kids a

Vitek1552 [10]

Answer:

<u>The correct answer is </u>

<u>C. k+d=130 </u>

<u>7k = 3d</u>

<u>Number of kids Dr. Irvine see in a week is 39.</u>

Step-by-step explanation:

1. Let's review the information given to answer the question correctly:

Number of patients Dr. Irvine see in a week = 130

Radio of kids to adults = 3:7 or 3/7

Number of Kids = k

Number of adults = d

2. Let's find the equations system that should be set up to find out how many kids Dr. Irvine see

k + d = 130 (Number of patients Dr. Irvine see in a week)

Including the ratio:

7k = 3d

Replacing d:

d = 130 - k

Now substituting:

7k = 3 * (130 - k)

7k = 390 - 3k

10k = 390

k = 390/10

<u>k = 39</u>

If 3,000 bacteria, with a growth constant (k) of 2.8 per hour, are present at the beginning of an experiment, in how many hours

Ivenika [448]

Given:

Initial number of bacteria = 3000

With a growth constant (k) of 2.8 per hour.

To find:

The number of hours it will take to be 15,000 bacteria.

Solution:

Let P(t) be the number of bacteria after t number of hours.

The exponential growth model (continuously) is:

$P(t)=P_0e^{kt}$

Where, $P_0$ is the initial value, k is the growth constant and t is the number of years.

Putting $P(t)=15000,P_0=3000, k=2.8$ in the above formula, we get

$15000=3000e^{2.8t}$

$\dfrac{15000}{3000}=e^{2.8t}$

$5=e^{2.8t}$

Taking ln on both sides, we get

$\ln 5=\ln e^{2.8t}$

$1.609438=2.8t$ $[\because \ln e^x=x]$

$\dfrac{1.609438}{2.8}=t$

$0.574799=t$

$t\approx 0.575$

Therefore, the number of bacteria will be 15,000 after 0.575 hours.
