We will solve it by this way-

2 m and 3 b can do a work in 8 days.

Then 3 m and 4 b do it in how many days.

=2*3*8=3*4*x

x=2*3*8/3*4

x=2*8/4

x=2*2

x=4 days

A culture started with 5000 bacteria after 5 hours it grew to 6500 bacteria predict how many bacteria will be present after 16 h

postnew [5]

Answer:

After 16 hours bacterial count will be 11600.

Step-by-step explanation:

Bacterial growth is always an exponential growth in a given culture.So the formula for the growth will be

Final counts of bacteria = Initial counts × $(rate of growth)^{time}$

Given from first part Initial counts = 5000

Final counts= 6500 and time of growth = 5 hours

Then we will get the value of rate of growth of bacteria from the bacteria

⇒ 6500 = 5000× $(rate)^{5}$

$(rate)^{5}= \frac{6500}{5000} = 1.3$

$Rate = \sqrt[5]{1.3} = 1.05$

Now again to get the value of bacteria after 16 hours

Final Count = 5000× $(1.05)^{16}$

= 5000×2.32

= 11600

you are attempting to guess a 3 digit number and have the following information. there are no 0s the number is even. the sum of

ss7ja [257]

The 3-digit number is 132

<h3>How to determine the 3-digit number?</h3>

The given parameters are:

Number of digits = 3
Sum of digits = 6
No 0s in the number
No repeated digit

The first highlight above implies that the number can be any of 100 to 999

The other highlights imply that the no digit can appear repeatedly, the highest digit in the number is 3, and the number must end with 2.

So, we have:

X32

The first digit is the smallest.

1 is smaller than 3 and 2.

So, we have

132

Hence, the 3-digit number is 132

Anne's potato salad recipe requires one pound of potatoes for every four people served. How many pounds of potatoes will Anne ne

Ierofanga [76]

Answer:

3.5 pounds for 14 people

Step-by-step explanation:

Given

1 pound = 4 people

Required

Determine the pounds for 14 people

Represent this with x; so, we have:

$1\ pound = 4\ people$

$x = 14\ people$

Cross Multiply

$x * 4 = 1 * 14$

$4x = 14$

Solve for x

$x = 14/4$

$x = 3.5$

<em>Hence, 3.5 pounds for 14 people</em>
