6 persons * $8= $48
4 popcorns * $6.25= $25
6 persons * $2.75= $16.5 (drinks)
$48+$25+$16.5= $89.50 total
You multiply 20,400 by 10 which will equal 204,000
Answer:
A=195.97 cm^2
Step-by-step explanation:
Area of a circle is given by
A = pi r^2
We are given the diameter. We need to find the radius
d= 2r
15.8 = 2r
Divide by 2
7.9 =r
Now we can find the area
A = pi * (7.9)^2
A = pi *62.41
Let pi = 3.14
A = (3.14) * 62.41
= 195.9674 cm^2
We round to the nearest hundredths
A=195.97 cm^2
Answer:
Step-by-step explanation:
We have given that:
There are 20 alligators in the swamp. Each year, the number of alligators increases by 25%. There are 25 crocodiles in the swamp. Each year, 10 new crocodiles join the swamp
Part A:
According to the above mentioned statement the function for representing the number of alligators and crocodiles in the swap throughout the year is:
Alligators = y=20(1.25)^x (x represents years)
crocodiles: y=10x+25
Part B:
Number of alligators after 4 years in the swap = y=20(1.25)^x
Number of alligators after 4 years in the swap = y=20(1.25)^4
Number of alligators after 4 years in the swap=48.82
This shows that about 48 to 49 alligators will be there in the swap after 4 year
Number of crocodiles after 4 years in the swap = y= 10(4)+25 = 65
Part C:
We will use the graph method to solve this part:
After approximately 7 years, the number of animals of each type will be the same, 95.
Answer:
2.45
Step-by-step explanation:
B+16.12=18.57. Take the sum and the given value and subtract the given value from the sum. You can do this on all problems like this.
