Answer: B) It is the product of the initial population and the growth factor after d days.
Step-by-step explanation: Given initial number of bacteria = 10.
Rate of increase = 20% each day = 0.2 .
Expression for finding the number of bacteria after d days is given by
, where d is the number of days.
We can see than initial population of bacteria is 10 and 10 is being multiplied with growth factor (1 + 0.2) after d days.
Therefore, correct option is B option.
B) It is the product of the initial population and the growth factor after d days.
Answer:
100
Step-by-step explanation:
2:3:5
20:30:50
20 + 30 + 50 = 50 + 50 = 100
Answer:
$28.80
Step-by-step explanation:
Multiply $24 by 20% (0.20)
24 x 0.2 = 4.80
So, the tip is $4.80
Add the tip to the price of the tab
24 + 4.8 = 28.8
So the overall price of the restaurant tab is $28.80

Answer:
29.9 °F
Step-by-step explanation:
The formular for mean is given as;
Mean = Sum of Terms / Number of terms
Number of terms = 6
Sum of terms = 35.5 + 30.8 + 27.3 + 32.1 + 23.8 + 29.9 = 179.4
Mean = 179.4 / 6 = 29.9
Answers:
- x = 9
- angle QRT = 18 degrees
- angle TRS = 72 degrees
=============================================================
Explanation:
The smaller angles QRT and TRS combine to the angle QRS which is 90 degrees.
(angle QRT) + (angle TRS) = angle QRS
(2x) + (8x) = 90
10x = 90
x = 90/10
x = 9
We'll then use this x value to find each angle
- angle QRT = 2x = 2*9 = 18 degrees
- angle TRS = 8x = 8*9 = 72 degrees
As a way to check the answer,
angle QRT + angle TRS = 18+72 = 90
so the answer is confirmed.
