A forest covers 73,000 acres. A survey finds that 0.2% of the forest is old-growth trees. How many
acres of old-growth trees are there?
There are acres of old-growth trees.
Type an integer or a decimal)
Answer:
143 acres.
Step-by-step explanation:
To find how many acres of old-growth trees there are, we need to find what 0.2% of 73,000 is.
To find a percent of a number, multiply the percent by the number.
0.2% is equal to 0.002.
73,000 x 0.002 = 143
So, 143 acres of the forest is old-growth trees.

Complete the following questions.
1. It costs Bill $35.50 to make a 3 tier chocolate cake. He marks his cakes up by 60%, what is the markup? What is the selling price of the cake?
2. Sue has $14.75 in making a flower arrangement. She marks them up by 45%. What is the markup? What is the selling price?
3. Jim goes to Walmart and purchases items that costs $98.25. The sales tax rate is 7%. How much tax does he pay? How much is his total?
4. Jill purchases a car for $19,250.95. The sales tax rate is 4.5%. How much sales tax does she pay? How much is the total cost of the car?
1. 35.50 increase 60% =
35.50 × (1 + 60%) = 35.50 × (1 + 0.6) = $56.80
2. 14.75 increase 45% =
14.75 × (1 + 45%) = 14.75 × (1 + 0.45) = 21.3875 = $21.39
3. 98.25 increase 7% =
98.25 × (1 + 7%) = 98.25 × (1 + 0.07) = 105.1275 = $105.13
4. 19250.95 increase 4.5% =
19250.95 × (1 + 4.5%) = 19250.95 × (1 + 0.045) = 20117.24275 = $20117.24

An amusement park charges an entrance fee plus an additional charge per ride that a person
goes on. The park would like to model the total amount, a, a person will pay as a function of
the number of rides, r, they go on. Amelia went on 7 rides and paid a total of $49.50. Lucas
went on 12 rides and spent a total of $67.00.
(49.50,7) (67,12)
(49.50,67) (7,12)

Answer:

Step-by-step explanation:
A sample of a radioactive isotope had an initial mass of 540 mg in
the year 2009 and decays exponentially over time. A measurement
in the year 2011 found that the sample's mass had decayed to 300
mg. What would be the expected mass of the sample in the year
2021, to the nearest whole number?
Answer:
16 mg
Step-by-step explanation:
[tex]N_0[/tex] = Initial mass of sample = 540 mg
t = Time taken = 2 years
[tex]t_{1/2}[/tex] = Half life of isotope
N = Final mass of sample = 300 mg
Radioactive decay is given by
[tex]N=N_0e^{-\dfrac{\ln 2}{t_{1/2}}t}\\\Rightarrow \ln\dfrac{N}{N_0}=-\dfrac{\ln 2}{t_{1/2}}t\\\Rightarrow t_{1/2}=-\dfrac{\ln2}{\ln\dfrac{N}{N_0}}t\\\Rightarrow t_{1/2}=-\dfrac{\ln2}{\ln\dfrac{300}{540}}2\\\Rightarrow t_{1/2}=2.358\ \text{years}[/tex]
In 2021 the number of years passed from 2009 would be 12 years
[tex]N=N_0e^{-\dfrac{\ln 2}{t_{1/2}}t}\\\Rightarrow N=540e^{-\dfrac{\ln 2}{2.358}12}\\\Rightarrow N=15.86\approx 16\ \text{mg}[/tex]
The expected mass of the sample in the year 2021 would be 16 mg.

Brady rented a car for two days at $25 a day plus
$0.15 per mile. If his total bill came to $102.50, how
many miles did Brady drive?
Answer:
He drove 350 miles.
Step-by-step explanation:
I need points.
Brady drove 16.67 miles extra.
What is division?One type of operation in mathematics is division. We divide the expressions or numbers into the same number of components during this operation.
Given, Brady rented a car for two days at $25 a day plus $0.15 per mile.
His total bill is $102.50.
We divide the 102.50 by 25.
That means, 102.50 / 25
= 4 is quotient and 2.50 is remainder.
Now we divide 2.50 by 0.15
That means, 2.50 / 0.15
= 16.67 miles
Therefore, 16.67 miles, Brady drove.

The number y of duckweed fronds in a pond after t days is y=a(1230.25)t/16, where a is the initial number of fronds. By what percent does the duckweed increase each day? Round your answer to the nearest whole number.
Answer:
[tex]56\%[/tex]
Step-by-step explanation:
The function is
[tex]y=a(1230.25)^{t/16}[/tex]
We need to convert it into the form
[tex]y=a(1+r)^n[/tex]
where r = Growth rate
n = Time taken
a = Initial quantity
[tex]y=a(1230.25)^{t/16}\\\Rightarrow y=a((1230.25)^{1/16})^t\\\Rightarrow y=1.56^t[/tex]
1.56 can be written as [tex]1+0.56[/tex], so
[tex]y=(1+0.56)^t[/tex]
So, [tex]r=0.56[/tex]
In percent [tex]0.56\times 100\%=56\%[/tex]
The duckweed will increase each day by [tex]56\%[/tex].

The Turtle's Equation: y= 2x + 12
The rabbit's Equation: y=5x
A) solve the system (using the substitution method)
(Hint: find x, and then use it to find y)
System:
y = 2x + 12
y = 5x
Answer:
A) y=2x+12. ( replace y with 5x) ➡️ 5x=2x+12 y=5x 5x-2x=12
➡️ 3x=12
3x/3=12/3
x=4
B) y=5x
y=5×4
y=20
