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].
Solve tree he system of equations by the substitution method.
12x + 3y =8
-4x = y + 8
Answer:
8x + 2y
Step-by-step explanation:
12x + 3y = 8 you need to transfer the no. 8 to left since it's positive, it will be negative once you tranfer that and the result is this 8x + 3y -8 =0. Then do it again on the second given, -4x = y + 8.
Tranfer the y variable to left, y is positive then it will be a negative. No need to transfer the no. 8. Then the result would be -4x - y + 8=0
To this solve this, wrote it like this:
12x + 3y –8
-4x - y + 8
——————
8x + 2y

what is this 59 divided 535
Answer:
9.07 [Rounded]
Step-by-step explanation:
535 divided by 59 is 9.07, which I rounded.
The value of the division 535 ÷ 59 is 9 with a remainder of 4 and the decimal form can be expressed as 9.067.
To find the value of division 535 ÷ 59, we can perform a long division.
To perform the calculation, we can use long division:
59 ) 535 ( 9
- 531
______
4
Divide the first digit of the dividend (5) by the divisor (59). Since 5 is less than 59, we bring down the next digit, making it 53.
Divide 53 by 59. The result is 0, as 53 is less than 59.
Bring down the next digit, making it 535.
Divide 535 by 59. The result is 9, as 59 can go into 535 nine times.
Multiply 9 by 59, which equals 531.
Subtract 531 from 535, which gives us a remainder of 4.
Therefore, the value of the division 535 ÷ 59 is 9 with a remainder of 4.
In decimal form, the division can be expressed as 9.067, indicating that 59 goes into 535 nine times with a remainder of 4.

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.

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% =

solve using Pythagoras Theorem (please)
Answer:
HA = 16.2 m
DE = 17 m
Step-by-step explanation:
From the base of the cuboid, HDA will form a right angle triangle, where;
DA = 15 m
HA = 6 m
HA is the hypotenuse
Using pythagoras theorem;
HA = √(15² + 6²)
HA = √(225 + 36)
HA = √261
HA = 16.155 m
Approximating to 1 decimal place gives;
HA = 16.2 m
Similarly, HDE will also form a right angle triangle.
Thus;
DE = √((HD)² + (HE)²)
HD = 16.2 m
HE = 5 m
Thus;
DE = √(16.2² + 5²)
DE = 16.95 m
Approximating to 1 decimal place gives
DE = 17 m
