Answer:
Step-by-step explanation:
a. This is a decay function, since the final value (A) gets smaller and smaller as the days pass by.
b. The bacteria is decreasing by 75% per day exponentially.
c. In order to calculate the amount of bacteria in a week we simply substitute the variable t for 7 (7 days in a week) and solve for A
A = 200(0.75)^7
A = 26.7 bacteria after 1 week
d. In order to calculate this we need to substitute the variable A with 100 and solve for t
100 = 200(0.75)^t ... divide both side by 200
0.5 = 0.75^t
[tex]\frac{ln(0.5)}{ln(0.75)}[/tex] = t
2.4 = t
It will be half the initial amount after 2.4 days.
These figures are similar. The perimeter and area of one are given. The perimeter of the other is also given. Find its area and round to the nearest tenth. erimeter = 20m Area = 19.6m ^ 2 rimeter = 34m Area=[ ? ] m^ 2
Answer:
Area of big diagram = 33.32 m²
Step-by-step explanation:
Given:
Both given diagram is similar
Perimeter of small diagram = 20 m
Area of small diagram = 19.6 m²
Perimeter of big diagram = 34 m
Find:
Area of big diagram
Computation:
Both given diagram is similar So,
Perimeter of small diagram / Area of small diagram = Perimeter of big diagram / Area of big diagram
20 / 19.6 = 34 / Area of big diagram
Area of big diagram = [19.6/20][34]
Area of big diagram = 33.32 m²
Answer:
56.6
Step-by-step explanation:
this equation (34/20)^2 * 19.6 = 56.644

Part B Point S is located at 5/4 on the number line. A student claims that the location of point S is to the right of the location of point P on the number line. *Explain whether the students claim is correct or in correct. *Write an equality that describes the relationship between the value of point P and the value of point S.
Number line can be found in the picture attached below
Answer:
The claim is incorrect ; Point S will be located to the left of Point P
2.5 > 1.25
Step-by-step explanation:
Location of point S = 5/4 = 1 1/4 = 1.25
From the number line ; location of point P = 2.5
Point S is lesser than P, therefore, point S would be located to the left of point P on the number line.
Inequality that describes the relationship between the value of point P and point S ;
Point P = 2.5 ; Point S = 1.25
Point P > Point S
2.5 > 1.25

Answer:
180-80=100
100-38=62
MJL=62
angle(m)=80
Answer:
<MJL = 62°
<m = 80°
x = 4
Step-by-step explanation:
in ∆JKL total angle aum is 180° and to find <L we have to subtract the given angles in this triangle from 180
that is
<L = 180-80-38 = 62°
then <MJL = 62° (alternative interior angle)
<JLM= 38° (alternative interior angle)
then <m = 180-62-38 = 80°

15 chocolate were distributed between raju and sanju in the ratio 2:3 . How many chocolates did raju receive?
Answer:
6chocolates
Step-by-step explanation:
Given
The total number of chocolate = 15chocolates
If it is divide into ratio 2:3
total ratio = 2+3
Total ratio = 5
Number of chocolate raju receives = 2/5 * 15
Number of chocolate raju receives = 2 * 3
Number of chocolate raju receives = 6chocolates
The number of chocolates that Raju received are; 6 chocolates
ProportionWe are told that;
Number of chocolates distributed = 15
Ratio of sharing between Raju and sanju = 2:3
Thus, fraction to be received by both of them are;
For Raju = 2/(2 + 3) = 2/5For Sanju = 3/(2 + 3) = 3/5Thus;
Amount of chocolates for Rajus = 2/5 × 15 = 6
In conclusion, Raju received 6 chocolates.

Step-by-step explanation:
a. What is the total cost (startup fee and monthly charge) to use the cell phone plan for 1 month?
answer for a: $95 + $55 = $150
b. Is there a proportional relationship between time and the cost of the cell phone plan?
answer for b: There is a proportional relationship between time and the cost of the cell phone plan because each month of time that passes, your phone will be charged $55. We know this because every month of Han's cell phone plan costs $55.
c. What is the total cost for x months? (Write an equation for the situation.)

The zookeeper find the lions in the zoo daily during the week the line graph shows the amount of meat in kilograms fair to the liens on each day of the week find the rate of change in the same amount of meat are fed to the alliance between Thursday and Friday
The changes is is the same amount of meat from Thursday to Friday is ___
Kilograms of meat
The rate of change is the same amount of meat from Thursday to Friday is 14 Kilograms of meat
Here, the line graph shows the amount of meat in kilograms fed to the lions on each day of the week.
From the line graph the amount of meat fed to the lines on Thursday is 58 kilograms
And the amount of meat fed to the lines on Thursday is 72 kilograms
Let x represents the rate of change in the amount of meat from Thursday to Friday.
So, the value of x would be,
x = 72 - 58
x = 14 kilograms
Thus, the rate of change in the same amount of meat are fed to the alliance between Thursday and Friday = 14 kilograms

The triangles shown are similar. Which side of triangle PQR corresponds to side LN in triangle MNL? Triangle L N P. Side L N is 12, N M is 10, M L is 14. Triangle P R Q. Side P R is 28, R Q is 24, Q P is 20. RQ PQ PR LM
Answer:
LN corresponds to RQ
Step-by-step explanation:
If we look at the diagram we find that LN corresponds to RQ, MN corresponds to QP and ML corresponds to PR .
The both triangles are similar as PQR is 2 times of MNL .
Therefore
PQR= 2MNL
PR= 2ML
28= 2(14)
QP= 2MN
20 = 2(10)
RQ =2 LN
24= 2(12)

RQ
