The common ratio of a geometric sequence is 3 and the 8th term is 4,374. What is the 4th term in this sequence?
Answer:
the first term is a1
the 8th term is a8
the 4th term is a4
we have:
[tex]a8=a1.3^{7}\\\\<=>4374=a1.3^{7}\\\\<=>a1=2[/tex]
with a1 = 0,002 => a4 = a1.3³ = 2.27 =54
Step-by-step explanation:
The 4th term of the given geometric sequence is 54.
What is geometrical progression series?A geometric progression is a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.
For example, the sequence 1, 4, 16, 64,… is a geometric sequence with a common ratio of r = 4.
The nth term of a GP is given as a[tex]r^{n-1}[/tex]
As per the given,
Common ratio r = 3
8th term = 4374
a(3)⁸⁻¹ = 4374
a = 2
The 4th term will be as, 2 x (3)⁴⁻¹ = 54
Hence "The 4th term of the given geometric sequence is 54".

Write the measure in descending order 0.5m - 480mm - 55cm
Answer:
480mm<55cm<0.5m
Step-by-step explanation:
millimeters means 100
centimeters means 10
meters means 1
there are 10mm in every 1cm and 100cm in every 1m
Answer:
55cm>0.5m>480mm
Step-by-step explanation:
as we know
1000mm=1m
100cm=1m
So we see
55=55cm
0.50=50cm
480=48cm

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.

Candace makes a sugar-water mixture for hummingbirds. She knows the amount of sugar used in the mixture is proportional to the amount of water used.
Which of the following could represent the relationship between the amount of sugar and water Candace should use in the mixture?
Answer:
the first image (the image with the upward sloping line)
Step-by-step explanation:
If the amount of sugar used in the mixture is proportional to the amount of water used, as more water is used, the more sugar is used. So, as more water is used, more sugar is used.
If the amount of water used is constant regardless of the amount of sugar, the appropriate graph would be the second graph. the graph with the straight line

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 points represented by the (x, y) coordinate pairs all lie on line "k". These are the points: (1,3), (2, 1), (3,-1). (4.-3), and (5,-5). What is the slope of line k? A.2 B.5 C.-3 D.-2
Answer:a
Step-by-step explanation:
Bsnanna
If the points (1,3), (2, 1), (3,-1). (4.-3) lie on line k, then the slope of line k is -2
Option D is the correct choice
The points that lie on the line k are:
(1,3), (2, 1), (3,-1). (4.-3), and (5,-5).
We can find the slope of the line k by picking any two points on the line
The slope m of a line passing through the points (x₁, y₁) and (x₂, y₂) is given by the formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
On the line k, let us select the points (1,3) and (2, 1)
x₁ = 1, y₁ = 3, x₂ = 2, y₂ = 1
[tex]m = \frac{1-3}{2-1} \\\\m= \frac{-2}{1}\\\\m= -2[/tex]
Therefore, the slope of the line k is -2

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.

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

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.
