The distance of the cruise liner from me 20 seconds later will be; 2600ft.
How far will the cruise liner be in 20 seconds?a) Since, the speed of the liner is 30ft/sec, it follows that after 20secs, the liner would cover; (30×20)ft = 600ft more; and consequently, the distance is now; √(2000²+600²) = ft.
b) For the boat to be 2500 ft away given the speed 30ft per sec; Time taken = 2500/30 = 83.3seconds. Hence, the boat will be more than 2500 feets away after 2 minutes.
c) If the boat's distance is 2000ft from me; it follows that the distance covered is 10 seconds is; √(2000²-1500²) = 1322.9ft
Hence, the speed to attain this distance is; 1322.9/10 = 132.29ft/sec.

What is the maximum number of consecutive odd positive integers that can be added together before the sum exceeds $401$
The maximum number of integers is 27 that can be added together before the summation of the A.P. Series exceeds 401.
According to the statement
We have a given that the maximum sum of the positive integers is 400.
And we have to find the value of n which is a maximum number of integers by which the value of sum become 400.
So, to find the value of the n we use the
A.P. Series'Summation formula
According to this,
S = n (n+1)/2
Here the value of s is 401
Then
S = n (n+1)/2
401 = n (n+1)/2
401*2 = n (n+1)
802 =n (n+1)
n (n+1) = 802
n^2 + n -802 =0
By the use of the Discriminant formula the
value of n becomes n = -28 and n = 27.
The negative value of n is neglected.
Therefore the value of n is 27.
So, The maximum number of integers is 27 that can be added together before the summation of the A.P. Series exceeds 401.

a vendor sold 25 dozens of mangoes. He was able to sell 3/5 of the total number of mangoes at 15.50 pesos and the remaining at 19.00 pesos each. How much was the total sales?
Answer: 422.5
Step-by-step explanation: To find how many mangoes were sold at 15.50 pesos, find 3/5 of the total number of mangoes. 3/5 of 25 is 15 because 3 (numerator) times 25 (mangoes) divided by 5 (denominator) is 15. 15 times 15.50 (price) is 232.5 pesos. Next we take the remaining mangoes (10) and multiply it by the price (19) to get 190 pesos. Add the sales and you get 422.5 pesos.
Answer:
422.50 pesos total
Step-by-step explanation:
3/5 ths of 25 = 15
(1/5th of 25 is 5, so we can multiply that number by 3 (3)(5) to get what 3/5ths of 25 are)
So, 15 mangoes were sold at 15.50 pesos
15 × 15.50 = 232.50
(why is this multiplication?
remember that repeated addition is multiplication. We are adding the cost of each mango (15.50) 15 times, which we could write as 15.50 + 15.50... 15 times, or we could simply multiply the two values :) )
Because this vendor has sold 15 of his mangoes, he has 10 left (25 - 15 = 10), so we multiply
10 × 19.00 to find the combined cost:
10 × 19.00 = 190.00
Now, we want to find the total sale (how much money he made in total, from all 25 mangoes)
So, let's add our two values together:
232.50
+ 190.00
422. 50
So, the vendor made 422.50 pesos total from his mangoes

The volume of the cylindrical water tank shown below is 490π feet^3. If the tank is 10 feet high, what does its radius r equal?
The cylindrical water tank with a volume of 490π feet³, and a height of 10 feet, has a radius of 7 feet.
The volume of a cylinder having a radius of r units, and a height of h units, is given by the formula, V = πr²h.
In the question, we are asked to find the radius (r), of a cylindrical water tank, with a volume of 490π feet³, and a height of 10 feet.
Substituting the value of V = 490π feet³, and h = 10 feet, in the formula for the volume of a cylinder, V = πr²h, we get:
490π feet³ = π.(r²)(10 feet).
Rearranging this, we can write:
r² = (490π)/(10π) feet²,
or, r² = 49 feet²,
or, r = √49 feet,
or, r = 7 feet.
Thus, the cylindrical water tank with a volume of 490π feet³, and a height of 10 feet, has a radius of 7 feet.

A poll worker analyzing the ages of voters found that mu = 65 and sigma = 5. what is a possible voter age that would give her zx = 1.14? round your answer to the nearest whole number.
If the value of μ is 65, σ is 5 and z is 1.14 then the value of possible voter age would be 70.6 years.
Given that value of μ is 65, σ is 5 and z is 1.14.
We have to calculate the possible voter age that can satisfy the given values of σ,μ and z.
We know that in z test,
z=X-μ/σ
in which μ is population mean,σ is population standard deviation.

3. A train travels 20 km at a uniform speed of 60 km/h and the next 20 km at a uniform speed of 80km/h. Calculate its average speed.
Answer:
Given,
Distance traveled = 20 km
Speed = 60 km/h
So, timetaken=DistanceSpeed=2060=13h
For the next journey
Distance traveled = 20 km
Speed = 80 km/h
So, timetaken=DistanceSpeed=2080=14h
Now,
Total distance traveled = 20 + 20 = 40 km
Total time taken = 13+14=712
We know,
Averagespeed=TotaldistancetraveledTotaltimetaken=40712=68.5 km/h
Hence the average speed of the train is 68.5 km/h

How to find the area below the curve by Riemann's sum
In this problem we must estimate the value of the area below the curve by finite number of rectangles using Riemann sums, whose expression is:
A ≈ [(b - a) / n] · ∑ f[a + i · (b - a) / n], for i = {0, 1, 2, 3, ..., n - 1} (1)
Where:
n - Number of rectanglesa - Lower limit of the interval.b - Upper limit of the interval.i - Index of the rectangle.The approximate area below the curve using five rectangles is: f(x) = 20 · x - x², a = 0, b = 20, n = 5
A ≈ [(20 - 0) / 5] · ∑ f[0 + i · (20 - 0) / 5]
A ≈ 4 · ∑ f(4 · i)
A ≈ 4 · [f(0) + f(4) + f(8) + f(12) + f(16)]
f(0) = 20 · 0 - 0² = 0
f(4) = 20 · 4 - 4² = 64
f(8) = 20 · 8 - 8² = 96
f(12) = 20 · 12 - 12² = 96
f(16) = 20 · 16 - 16² = 64
A ≈ 4 · (0 + 64 + 96 + 96 + 64)
A ≈ 1280
And using ten rectangles:
A ≈ [(20 - 0) / 10] · ∑ f[0 + i · (20 - 0) / 10]
A ≈ 2 · ∑ f(2 · i)
A ≈ 2 · [f(0) + f(2) + f(4) + f(6) + f(8) + f(10) + f(12) + f(14) + f(16) + f(18)]
f(0) = 20 · 0 - 0² = 0
f(2) = 20 · 2 - 2² = 36
f(4) = 20 · 4 - 4² = 64
f(6) = 20 · 6 - 6² = 84
f(8) = 20 · 8 - 8² = 96
f(10) = 20 · 10 - 10² = 100
f(12) = 20 · 12 - 12² = 96
f(14) = 20 · 14 - 14² = 84
f(16) = 20 · 16 - 16² = 64
f(18) = 20 · 18 - 18² = 36
A ≈ 2 · (0 + 36 + 64 + 84 + 96 + 100 + 96 + 84 + 64 + 36)
A ≈ 1320
And using infinite rectangles:
A ≈ [(b - a) / n] · ∑ f[a + i · (b - a) / n]
A ≈ (20 / n) · ∑ [20 · (20 / n) · i - (20 / n)² · i²]
A ≈ (20 / n) · ∑ [400 · i / n - 400 · i² / n²]
A ≈ ∑ (8000 · i / n² - 8000 · i² / n³)
A ≈ (8000 / n²) · ∑ i - (8000 / n³) · ∑ i²
A ≈ (8000 / n²) · [n · (n + 1) / 2] - (8000 / n³) · [n · (n + 1) · (2 · n + 1) / 6]
A ≈ (8000 / n²) · [(n² + n) / 2] - (8000 / n³) · [(n² + n) · (2 · n + 1) / 6]
A ≈ 4000 · (n² + 2) / n² - (8000 / n³) · [(2 · n³ + 3 · n² + n) / 6]
A ≈ 4000 · (1 + 2 / n²) - (4000 / 3) · [2 + 3 · (1 / n) + (1 / n²)]

In a movie theater, the number of seats in a row is 8 greater than the total number of rows. How many rows are in the movie theater, if the total number of seats in the theater is 884?
Answer:
26 rows
Step-by-step explanation:
this is like a rectangle length×width situation.
seats per row = s
number of rows = r
s × r = 884
s = r + 8
so, we can use e.g. the second equation in the first :
(r + 8) × r = 884
r² + 8r = 884
r² + 8r - 884 = 0
the general solution to such a quadratic equation is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
x = r
a = 1
b = 8
c = -884
r = (-8 ± sqrt(8² - 4×1×-884))/(2×1) =
= (-8 ± sqrt(64 + 3536))/2 = (-8 ± sqrt(3600))/2 =
= (-8 ± 60)/2 = -4 ± 30
r1 = -4 + 30 = 26
r2 = -4 - 30 = -34
a negative number did not make any sense for the number of rows, so r = 26 is our answer.

c. They have the same vertical shift.
A vertical shift is just an alternate within the y-price of each characteristic. it's miles literally picking up the entire characteristic or graph and moving the whole element up or down. If it's far moved up, we add to the y-cost, if it's far moved down, we subtract from the y-cost.
Vertical shift and lateral shift are phenomena because of the refraction of mild rays once they journey from one medium into every other. while light rays travel across two parallel surfaces, the emergent rays from the second one floor are parallel to the incident rays on the primary floor.
The segment Shift is how far the function is shifted horizontally from the standard position. The Vertical Shift is how long way the function is shifted vertically from the same old function.

The members of a cooking club are making cakes, which they will sell at a street fair for $8 apiece. It cost $30 for a booth at the fair, and the ingredients for each cake cost $2. At some point, the club members will sell enough cakes so that their sales cover their expenditures. How many cakes will they have sold?
They need to sell 5 pieces to cover their expenditures (have a profit of zero).
How many cakes will they have sold?
We know that the costs are:
$30 for the booth at the fair.$2 for each piece of cake they sell.And the revenue is:
$8 for each piece of cake.So, the profit (the difference between the revenue and the cost) for selling x pieces is:
p(x) = $8*x - $2*x - $30
p(x) = $6*x - $30
We want to find the value of x such that p(x) = 0, then:
0 = $6*x - $30
x = $30/$6 = 5
They need to sell 5 pieces to cover their expenditures (have a profit of zero).

Write formal proofs using the HL Theorm.
Answer:
Given PR is perpendicular to QS, and PQ and PS are congruent. Angle PRQ and angle PRS are right angles by the definition of perpendicular segments. Therefore triangle PRQ and triangle PRS are right triangles. Segment PR is congruent to segment PR by the reflexive property of congruence. By the HL Theorem, triangles PRQ and PRS are congruent.
