Answer: Decompose means the opposite, to take apart

Step-by-step explanation: In this lesson, the words composition and decomposition are used to describe how irregular figures can be separated into triangles and other polygons. The area of these parts can then be added together to calculate the area of the whole figure.

Each bacterium in a petri dish splits into 2 bacteria after one day. The function b(d) = 600 • 24 models

TiliK225 [7]

Answer:

(a)Initial Number of Bacteria=600

(b) $\text{Number of bacteria after 5 days}=19200$

Step-by-step explanation:

Given an initial number $b_0$ of bacteria in a petri dish, and each bacteria splits into 2 bacteria after one day.

The function $b(d) = 600 \cdot 2^d$ models the number of bacteria, b after d days.

Part A

Given $b(d) = 600 \cdot 2^d$

When d=0,

The initial number of bacteria in the petri dish,

$b_0=b(0) = 600 \cdot 2^0=600$

Part B

After 5 days, when d=5

$b(5) = 600 \cdot 2^5=600 \cdot 32\\\text{Number of bacteria after 5 days}=19200$

How many mEq of KCI will the patient receive in 24 hours?

Brilliant_brown [7]

10% = 10g/100ml. Ergo, 15ml/100ml (10g) = 1500mg of KCL
.9% NACL = 9g/1000mL, Ergo = 9000mg NaCl
Now we have to figure out how many mEqs of each salt we have.
MW of NaCl = 58.5
MW of KCl = 74.5
So, in moles, we have:
1500 KCl / 74.5 = 20.13 mmol KCl
9000 NaCl / 58.5 = 153.85mmol NaCl
Because the valence of both ions is one, as an example, it would be both 20.13 mEq of Cl- and K+ from 20.13 mmoles of KCL.
So, just add the two together, 20.13 + 153.85 = 174-ish.

(b) If you put $9050 in the ATM each day, what percent of the days in a month should

lora16 [44]

Answer:

23.33%

Step-by-step explanation:

The computation of the percentage of days in a month for running out of cash is shown below:

Percentage of running out of Cash is

= (Relevant Occurrence of an event ÷ Total number of events) × 100%

where,

The Relevant occurrence of an event is 7 (105,94,101,98,94,96,92)

And, the total number of events is 30 i.e. 30 days

So, the percentage is

= 7 ÷ 30 × 100

= 23.33%
