Answer:
Altitude of a Cylinder
Step-by-step explanation:
Altitude of a Cylinder can be seen as a form of segment between the plane of a base to the plane of another base in which the height of the cylinder can be said to also be the length of the altitude meaning both the height and the length of the cylinder can be said to be equal which is why the axis of a cylinder is the segment which contains the centers of the two bases.
ALTITUDE OF A CYLINDER can also be seen as the distance between the bases of a cylinder which is the shortest line segment that occur between the possibly extended bases which is why ALTITUDE OF A BASE is a segment with its endpoints on the planes of
the bases that is perpendicular to the planes
of the bases.

The common ratio of a geometric series is 3 and the sum of the first 8 terms is 3280.
What is the first term of the series?
Answer:
The first term of the geometric series is 1
Step-by-step explanation:
In this question, we are tasked with calculating the first term of a geometric series, given the common ratio, and the sum of the first 8 terms.
Mathematically, the sum of terms in a geometric series can be calculated as;
S = a(r^n-1)/( r-1)
where a is the first term that we are looking for
r is the common ratio which is 3 according to the question
n is the number of terms which is 8
S is the sum of the number of terms which is 3280 according to the question
Plugging these values, we have
3280 = a(3^8 -1)/(3-1)
3280 = a( 6561-1)/2
3280 = a(6560)/2
3280 = 3280a
a = 3280/3280
a = 1
Final answer:
To find the first term of a geometric series with a common ratio of 3 and a sum of the first 8 terms being 3280, we use the sum formula for a geometric series and isolate the first term 'a'. After plugging in the values and simplifying, we find that the first term 'a' is equal to 1.
Explanation:
The student is asking about the first term of a geometric series with a known common ratio and the sum of the first 8 terms. The common ratio for this series is 3, and the sum of the first 8 terms (S8) is 3280. To find the first term (a), we'll use the following formula for the sum of the first N terms of a geometric series:
S_N = a * (1 - x^N)/(1 - x),
where 'SN' is the sum of the first N terms, 'a' is the first term, 'x' is the common ratio, and 'N' is the number of terms. In this case, x=3 and S_8=3280.
Solving for 'a' gives us:
3280 = a * (1 - 3^8)/(1 - 3)
The first term (a) can now be calculated by isolating 'a' on one side of the equation.
a = 3280 / ((1 - 3^8)/(1 - 3))
a = 3280 / (1 - 6561)/(-2)
a = 3280 / (6560/2)
a = 3280 / 3280
a = 1.
Therefore, the first term of the geometric series is 1.

David loves his dog Thor and he wants to create a rectangular enclosure that has an area of 1600ft² for the dog to stay in while no one is home. David has a total of 120 feet of fencing available and he wants to use the wall of his garage as one of the sides of the enclosure. What are the dimensions of the enclosure?
Make a Sketch of the rectangular enclosure and label the sides using variable(s).
Write and solve an equation(s) that model this situation.
What are the dimensions of the rectangular enclosure?
Answer:
80 feet by 20 feet
Step-by-step explanation:
Area of the rectangular enclosure = 1600ft²
Area, lw=1600
w=1600/l
Perimeter, 2w+l=120 feet
Substituting w=1600/l into the perimeter
2(1600/l)+l=120
3200/l+l=120
[tex]\dfrac{3200+l^2}{l}=120\\ 3200+l^2=120l\\l^2-120l+3200=0\\l^2-40l-80l+3200=0\\l(l-40)-80(l-40)=0\\(l-40)(l-80)=0\\l-40=0\:or\:l-80=0\\l=40\:or\:l=80[/tex]
When l=40, w=1600/40=40 feet
When l=80, w=1600/80=20 feet
Since the enclosure is rectangular, the acceptable dimensions are:
Length =80 feet
Width =20 feet
In 1906 Americans consumed an average of 26.85 gallons of whole milk per year. By 1998 the average consumption was 8.32 gallons. What is the percent decrease in consumption of whole milk?
Answer: 69.01%
Step-by-step explanation:
In 1906 Americans consumed an average of 26.85 gallons of milk per year while by 1998 the average consumption was 8.32 gallons.
To get the percent decrease in consumption of whole milk goes thus:
We first find the amount of decrease in the milk consumed. This will be:
= 26.85 - 8.32
= 18.53
Percentage decrease
= 18.53/26.85 × 100
= 0.6901 × 100
= 69.01%
The areas of the squares adjacent to two sides of a right triangle are 32units^2 and 32 units^2. Find the length, x, of the third side of the triangle.
Answer:
The length of the third side of the triangle is 8 units
Step-by-step explanation:
Here, since the two sides are adjacent a square, what this means is that the length of the square equals the length of the sides of the triangle adjacent to it.
Mathematically, the formula for the area of a square is L^2
With an area of 32 square units, the length of the side of this triangle is thus √(32) =
4√2 units
So we have two sides of the right triangle with length 4√2 units
Now we should know that this right triangle is an isosceles right triangle since the lengths of the adjacent and the opposite are equal.
Now to calculate the length of the third side which is the hypotenuse, we make use of the pythagoras’ theorem which states that the square of the longest side of a right triangle which is the hypotenuse is equal to the sum of the squares of the other two sides
Thus mathematically, the square of the hypotenuse length is 32 + 32 = 64
Let’s call the hypotenuse h for documentation purposes
h^2 = 64
h = √64
h = 8 units

The amount a money in the bank account can be expressed by the exponential equation A=300(1.005)^12t where A is the amount in dollars and t is the time in years. About how many years will it take for the amount in the account to be more than $900?
Answer:
It will take more than 18.35 years for the amount in the account to be more than $900
Step-by-step explanation:
The amount in the bank account can be expressed by the exponential equation :
[tex]A=300(1.005)^{12t}[/tex]
Where A is the amount in dollars
t is the time
We are supposed to find About how many years will it take for the amount in the account to be more than $900
So, [tex]300(1.005)^{12t} >900[/tex]
[tex](1.005)^{12t} > \frac{900}{300}[/tex]
[tex](1.005)^{12t} > 3[/tex]
t>18.35
Hence It will take more than 18.35 years for the amount in the account to be more than $900

Answer:
d. The speeds in race A are likely to be near 145 mph and the speeds in race B are likely to be near to 153 mph.
Step-by-step explanation:
For the boxplot for Race A, the following is obtained from the attached diagram
The range of speed of the race is= Highest - Lowest
170 - 120= 50
The 1st Quartile is = 142
The 2nd Quartile is = 153
The 3rd Quartile is = 165
The Inter quartile range = 3rd quartile - 1st quartile = 165-142= 23
For the boxplot for Race B
The following values is obtained from the attached image.
The range of speed of the race is
Highest speed - Lowest speed
165 - 125= 40
The 1st Quartile is = 139
The 2nd Quartile is = 145
The 3rd Quartile is 150
The Inter quartile range = 3rd quartile- 1st quartile = 150 - 139 = 11
From the values above, we can see that ,
The speeds in race A are likely to be near 145 mph and the speeds in race B are likely to be near to 153 mph.

Kelly combines 6.54 ounces of strawberries with 6.09 ounces of blueberries to make fruit bowls.She pours the fruit equally into three bowls, and has 1.68 ounces of fruit left over. How many ounces of fruit are in each bowl?
Answer:
3.65 ounces in each bowl
Step-by-step explanation:
Strawberry=6.54 ounces
Blueberry=6.09 ounces
If Kelly combines the two fruits to make fruits bowls
Then,
6.54 ounces of strawberry + 6.09 ounces of blueberry=12.63 ounces of fruits.
She pours the fruits equally in each bowl and has a leftover of 1.68 ounces.
Let quantity in each bowl = x
There are 3 bowls
Total quantity in three bowls=3x
Leftover=1.68
Total fruits = 12.63
We have the equation
3x+1.68=12.63
Subtract 1.68 from both sides
3x=12.63-1.68
3x= 10.95
Divide both sides by 3
x=10.95/3
x=3.65
Answer:
3.65 ounces of fruit in each bowl
Step-by-step explanation:
If the combination was made with 6.54 ounces of strawberries and 6.09 ounces of blueberries, the total ounces of fruit used is 6.54 + 6.09 = 12.63 ounces.
The remaining after dividing in three bowls is 1.68, so the amount used is 12.63 - 1.68 = 10.95 ounces
If we divide this amount of fruit by three bowls, we have:
Amount of fruit per bowl = 10.95 / 3 = 3.65 ounces

[2.5] [0.75] [262.5]
# of hotdogs sold was 75
# of chips sold was 100
Step-by-step explanation:
got it right on edge ya digg
The number of hot dogs is 75 while the number of snacks is 100.
The linear equation to solve the question will be:
h + s = 175 ........ i
2.50h + 0.75s = 262.50 ........ ii
From equation i, s = 175 - h ..... iii
Put equation iii into ii
2.50h + 0.75s = 262.50
2.50h + 0.75(175 - h) = 262.50
2.50h + 131.25 - 0.75h = 262.50
Collect like terms
2.50h - 0.75h = 262.50 - 131.25
1.75h = 131.25
h = 131.25/1.75
h = 75
The number of hot dogs is 75 while the number of snacks is 100.

How many times does 2/3 go into 2?
Answer: 3 times
Step-by-step explanation:
2/(2/3)=3
Answer: 3 times.
Step-by-step explanation:
To find how many times 2/3 goes into 2, convert 2 to a fraction with the same denominator as 2/3.
You can do this by multiplying the fraction 2/1 by 3/3 to make the denominator equal 3:
[tex]\frac{2}{1}*\frac{3}{3} =\frac{6}{3}[/tex]
Then, you can divide the fractions. Because 6/3 and 2/3 have the same denominator, you can simply divide 6 by 2.
2/3 goes into 2 three times.
