if there are 10 people per race, and 2222 people have come in first place, then how many races have happened?
Answer:
22,220
Step-by-step explanation:
Because you multiply by 10 because 2222 times 1 is 1 person per race, so if there is 10 then you multiply by 10.

Environmentalists estimate an annual population decrease of giraffes in the wild of 3.5% due to development. This can be modeled by the function p(x) = 140,000(0.965)^x, where x is the number of years of tracking the populations. Conservationists have developed a sanctuary that has shown the ability to increase the population by 0.85% per year. The increase can be modeled by the function S(p) = p(1.0085)^x.
Which function represents S(p(x)), rounded to the nearest ten thousandth?
A. S(p(x)) = 135,100(0.9732)^x
B. S(p(x)) = 135,100(1.9735)^x
C. S(p(x)) = 140,000(0.9732)^x
D. S(p(x)) = 140,000(1.9735)^x
Answer:
S(p(x)) = 140,000(0.9732)^x
Step-by-step explanation:
Given the population functions:
ENVIRONMENTALIST: decline by 3.5% annually
p(x) = 140,000(0.965)^x
CONSERVATIONISTS: Increase by 0.85% annually ;
S(p) = p(1.0085)^x
Formulate S(p(x)) rounded to the nearest ten thousand
p(x) = 140,000(0.965)^x
S(p) = p(1.0085)^x
S(p(x)) = p(1.0085)^x
Where p(x) = 140,000(0.965)^x
S(p(x)) = 140,000(0.965)^x(1.0085)^x
S(p(x)) = 140,000(0.9732025)^x
S(p(x)) = 140,000(0.9732)^x

(2) A clock at London’s Heathrow airport chimes every half hour. At the beginning of the
n’th hour, the clock chimes n times. (For example, at 8:00 am the clock chimes 8 times,
at 2:00 pm the clock chimes fourteen times, and at midnight the clock chimes 24 times.)
The clock also chimes once at half-past every hour. Determine how many times in total
the clock chimes in one full day. Use sigma notation to write the form of the series before
finding its sum.

You go to the store and notice the people standing in line. 7 adults and 4 children. If this ratio stays the same and there 55 people in the store. how many would be children?
Answer:
20
Step-by-step explanation:
7+4=11
11*5= 55
4*5=20 :)
The number of children and adults will be 35 and 20, respectively.
What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
You go into the store and observe the folks in queue. There are 7 adults and 4 children. If this ratio remains constant and there are 55 people in the store.
7x / 4x = constant
Then the equation is given below.
7x + 4x = 55
11x = 55
x = 11
Then the number of adults is given as,
7x = 7 (5) = 35
Then the number of children is given as,
4x = 4 (5) = 20
The number of children and adults will be 35 and 20, respectively.
More about the ratio and the proportion link is given below.

So angle A is equal to angle C
Let Angle A be x
And angle ABD is equal to 90 degree
So in triangle ADB
90+32+x=180 (angle sum property)
x=180-122
x=58
As angle A and angle C are equal
So angle C=58 degrees

Anne owns a used car lot and in order to get cars to sell, she buys used cars at an
auction place. It costs $200 to attend the auction and she buys used cars at
$2,000 each. Last Tuesday, she purchased 10 cars. Which of the following
functions correctly represents this situation in function notation?
f(x) = 10x + 200
f(x) = 200x + 2,000
f(x) = 2,000x + 10
f(x) = 2,000x + 200
Answer:
It would be 2,000x+200
Step-by-step explanation:
okay it costs $200 to attend so that's a cost you are going to have to pay regardless. The $2,000 depends on how many cars you buy. So it would be 2,000 (times how ever many cars you buy) plus the $200.
