Identify the value of r and a1 for each geometric
series.
2 + 3 + 4.5+ 6.75 + ...
Given:
The given geometric series is [tex]2 + 3 + 4.5+ 6.75 + ...[/tex]
We need to determine the value of r and a₁
Value of a₁:
The term a₁ denotes the first term of the geometric series.
Hence, from the given series, the first term of the series is 2.
Thus, a₁ = 2.
Therefore, the value of a₁ is 2.
Value of r:
The term r denotes the common ratio between the terms in the geometric series.
The value of r is given by
[tex]r=\frac{3}{2}=1.5[/tex]
[tex]r=\frac{4.5}{3}=1.5[/tex]
[tex]r=\frac{6.75}{4.5}=1.5[/tex]
Thus, the value of r is 1.5

Imagine we have a piece of string 25,000 miles long, just long enough to exactly circle the globe at the equator. We take the string and fit it snugly around the equator, over oceans, deserts and jungles. When we have completed our task, we find that the string is just one yard too long. To overcome the error, we decide to tie the ends together and to distribute the extra 36 inches evenly over the entire 25,000 miles, figuring that it will never be noticed. How far do you think the string will stand off from the ground at each point, merely by virtue of the fact that it is 36 inches (3 feet) too long? Explain your answer.
Answer: just an extra one foot
Step-by-step explanation:
Given that the length of the piece of string = 25,000 miles
Since the string is long enough to exactly circle the globe at the equator over oceans, deserts and jungles. We can say that the string could completely circle a sphere
Assuming that the earth is a perfect sphere.
The circumference of the circle = 25,000 mile.
But note that the circumference of a circle is directly proportional to the radius. If you double the radius, the circumference will also be doubled. Half the circumference, half the radius. Increase the circumference by 30%, radius will also be increased by 30% and so on.
In this question, the radius is being increased by 3 feet, so we need to know that as a fraction of the original radius.
Circumference = 2πr
Let's also convert miles to feet
25000 × 5280 = 2(3.143)r
r = 132 × 10^6/2π
r = 21008452.5 feet
3 feet - that's how far off the ground we're lifting the string out of 21008452.5 feet is close to one part in 25000 miles. The string was 132000000 feet long to start with, so we need just an extra 1 foot.

Please kindly check the attached file for more
Answer:
8π
Step-by-step explanation:
first the equation for a cone is [tex]\pi r^2\frac{h}{3}[/tex]
[tex]V=\pi *3^{2} *\frac{8}{3} \\ =\pi *9*\frac{8}{3} \\ =\frac{72}{3} \pi \\ =24\pi[/tex]
so since Abigail spilled 2/3 of the water then you do
[tex]24\pi * \frac{1}{3}\\ =8\pi[/tex]
so overall the volume of the remaning water is 8π.
A rectangle has a height of 6k^3 and a width of 2k^2 + 4K +5 what is the area
Answer:
The answer is 12k^5+24k^4+30k^3.
Step-by-step explanation:
You want to multiply the height by width to find area. Multiply 6k^3 times 2k^2+4k+5. 6k^3(2k^2+4k+5)= 12k^5+24k^4+30k^3.
Final answer:
The area of a rectangle with a height of 6k³ and a width of 2k² + 4k + 5 is calculated by multiplying the height by the width, resulting in 12k⁵ + 24k⁴ + 30k³.
Explanation:
To calculate the area of a rectangle, you multiply the height by the width. The given height of the rectangle is 6k³ and the width is 2k² + 4k + 5. Applying the formula for the area of a rectangle, we have:
A = height × width
A = 6k³ × (2k² + 4k + 5)
To find the area, distribute the height into each term of the width:
A = (6k³ × 2k²) + (6k³ × 4k) + (6k³ × 5)
A = 12k⁵ + 24k⁴ + 30k³
The area of the rectangle is 12k⁵ + 24k⁴ + 30k³.

solve for y
64−(3y+8y+y)÷40=37
Answer:
y= 90
Step-by-step explanation:
64−(3y+8y+y)÷40=37
Combine terms in the parentheses
64−(12y)÷40=37
Subtract 64 from each side
64-64−(12y)÷40=37-64
-(12y)÷40=-27
Multiply each side by 40
-(12y)÷40*40=-27*40
-12y =-1080
Divide each side by -12
-12y/-12 = -1080/-12
y =90
Answer:
y= 90
Step-by-step explanation:
64−( 3y+8y+y 40 )=37 64+ −3 10 y=37 −3 10 y+64=37
Step 2: Subtract 64 from both sides.
−3 10 y+64−64=37−64 −3 10 y=−27
Step 3: Multiply both sides by 10/(-3).
( 10 −3 )*( −3 10 y)=( 10 −3 )*(−27) y=90

Maria has 56.20 feet of ribbon to use for a border around a rectangular bulletin board in her
classroom. The board is 4.47 feet tall and 7.25 feet wide. How many feet of ribbon will Maria
have left after she puts the border around the bulletin board?
Answer:
32.76 ft
Step-by-step explanation:
step 1
Find the perimeter of the rectangular bulletin board
The perimeter of rectangle is given by
[tex]P=2(W+H)[/tex]
where
W is the width
H is the height
we have
[tex]W=7.25\ ft\\H=4.47\ ft[/tex]
substitute
[tex]P=2(7.25+4.47)=23.44\ ft[/tex]
step 2
Subtract the perimeter from the total feet of ribbon
so
[tex]56.20-23.44=32.76\ ft[/tex]

Horse: 45 beats per minute
Cow: 65 beats per minute
Dog: 90 beats per minute
The Richter scale is used for measuring the magnitude of an earthquake. The Richter magnitude is given R = 0.67log(0.37E) + 1.46 where E is the energy (in kilowatt hours) released by the earthquake. If an earthquake release 1,770,000 kilowatt hours of energy, what is the earthquake's magnitude?
Answer:
R=3.897
Step-by-step explanation:
Given the magnitude measured by the Ritcher scale is given as;
R = 0.67log(0.37E) + 1.46 where E= is the energy (in kilowatt hours)
If E=1,770,000 then
R= 0.67log(0.37*1770000)
R=0.67log(654900)
R=0.67*5.81617
R=3.897
Final answer:
To determine the magnitude of an earthquake that released 1,770,000 kilowatt hours of energy using the Richter scale formula, the calculated magnitude is approximately 5.51.
Explanation:
The Richter scale is used for measuring the magnitude of an earthquake. Given the Richter magnitude formula
R = 0.67log(0.37E) + 1.46
where E is the energy (in kilowatt hours) released by the earthquake, we can calculate the magnitude of an earthquake that released 1,770,000 kilowatt hours of energy.
First, substitute the given energy value into the formula:
R = 0.67log(0.37*1770000) + 1.46.
Performing the calculation:
0.37 * 1,770,000 = 654,900
log(654,900) = 5.816
R = 0.67 * 5.816 + 1.46
R ≈ 5.51
Therefore, the earthquake's magnitude on the Richter scale is approximately 5.51.
If Chickens lay about 12 eggs about every 4 days how many will they lay in 1 year 2 months and 3 days?
Answer:
1284 Eggs
Step-by-step explanation:
To work this out you would first have to know how many days there are in a year, which is 365. Then you would need to add the amount of days in January and February. January has 31 days and February would have 29, and so 29 plus 31 is 60. Then you would add 60 to 365, which is 425. Then you would add 3 to 425, which is 428. Then you would divide 428 by 4, which is 107. Then you would multiply 107 by 12, which is 1284.
1) Find out how many days there are in a year.
There are 365 days in a year
2) Add 31 to 29.
[tex]31+29=60[/tex]
3) Add 60 to 365.
[tex]365+60=425[/tex]
4) Add 3 to 425.
[tex]425+3=428[/tex]
5) Divide 428 by 4.
[tex]428/4=107[/tex]
6) Multiply 107 by 12.
[tex]107*12=1284[/tex]
