Eli was swimming upstream in a river and lost a plastic bottle at bridge A. He noticed the loss after swimming 10 minutes , so immediately started to swim downstream to catch it. He caught it at bridge B, which was 1 mile away from bridge A. What was the rate of water flow in miles per hour?
Using proportions, it is found that the rate of water flow was of 6 miles per hour.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, the bottle flowed 1 mile in 10 minutes. How much does it flow in 1 hour = 60 minutes? The rule of three is given by:
1 mile - 10 minutes
x miles - 60 minutes
Applying cross multiplication:
10x = 60
x = 60/10
x = 6.
Hence, the rate of water flow was of 6 miles per hour.

Which pair of angles are vertical angles?
/_ZRQW and /_ZWQV
/_ZRQT and /_ZTQV
/_ ZRQW and /_ZTQU
/_ZRQS and /_ZSQU
Answer:
(c) is correct.
Step-by-step explanation:
When two lines cross each other, the angles opposite to each other are called vertically opposite angles. They are always equal.
In this given figure,
Line TW and RU cross each other at Q, it means
\(\angle RQW=\angle TQU\) (vertically opposite angles)

Find the distance between the integers on a number line. 9 and -9
Answer:
18 units
Step-by-step explanation:
First, -9 to 0 is 9 units. Next 0 to 9 is also 9 units. Added up, this gives a total of 18 units.
Hope this helps! :)
Answer:
18
Step-by-step explanation:
You can do this two ways:
From -9 to 0, the distance is 9 units.
From 0 to 9, the distance is 9 units.
Add the two distances together, and you get 18 units.
You can also do this with the distance formula for a number line.
The distance, d, between numbers a and b on the number line is:
d = |a - b|
Our numbers are -9 and 9. It does not matter which number you call a and which you call b. Since the expression has absolute value in it, the answer will always come out non-negative.
d = |-9 - 9| = |-18| = 18
If you do it the other way, you get:
d = |9 - (-9)| = |9 + 9| = |18| = 18

Answer:
perimeter = 16 ft
Step-by-step explanation:
You want the perimeter of an isosceles triangle with side length 5 ft and altitude 4 ft.
Base lengthThe side lengths being equal mean the triangle is isosceles. That also means altitude PS bisects the peak angle and segment QR. Once we find the length QS using the Pythagorean theorem, we can double that measure to find QR.
The Pythagorean theorem tells us ...
QS² +PS² = QP²
QS² +(4 ft)² = (5 ft)²
QS² = (25 ft²) -(16 ft²) = 9 ft² . . . . . evaluate squares, subtract 16 ft²
QS = √(9 ft²) = 3 ft
Now we know the base length is ...
QR = 2·QS = 2(3 ft) = 6 ft
PerimeterThe perimeter is the sum of the outside edge lengths:
Perimeter = PQ +QR +RP
Perimeter = (5 ft) +(6 ft) +(5 ft) = 16 ft
The perimeter of ∆PQR is 16 feet.
__
Additional comment
With some practice, you can learn to recognize a 3-4-5 right triangle. That is the triangle used here for each of the right triangles that make up ∆PQR. Once you identify the long side as 4 and the hypotenuse as 5, you know immediately the short side is 3.
The set {3, 4, 5} is called a "Pythagorean triple." Other triples commonly seen in high school problems are {5, 12, 13}, {7, 24, 25}, {8, 15, 17}. Legs of these lengths form a right triangle. Knowing any two (or their ratio) tells you immediately the value of the third. Of course, these triples can be scaled by any factor. (3, 4, 5) scaled by 2 is (6, 8, 10), another commonly seen triple.
There are no isosceles right triangles that have integer values for both the legs and the hypotenuse. If the legs are both 4, the hypotenuse will be 4√2 ≈ 5.657... (an irrational number), not 5.
What is the product of 2 over 3y and y?
12 over 3y
2 over 3
2 over 3y
22 over 3y
The product of 2/3y and y is \(2/3y^2.\)
The product of 2/3y and y can be found by multiplying the numerators and denominators separately.
To multiply the numerators, we multiply 2 and 1 (since y can be written as y/1).
This gives us 2.
To multiply the denominators, we multiply 3y and 1.
This gives us 3y.
Therefore, the product of 2/3y and y is \(2/3y * y =\) \(2/3y^2.\)
In general, when multiplying fractions, we multiply the numerators and the denominators separately.
So, if we have a fraction a/b and another fraction c/d, their product would be ac/bd.
However, in this specific case, the expression can be simplified further.
Since we have y in both the numerator and denominator, they cancel out, leaving us with \(2/3y^2.\)
To summarize, the product of 2/3y and y is \(2/3y^2.\)

\(\frac{3x-7y}{8}\) × \(\frac{6}{3x-7y}\) ← cancel 3x - 7y on numerator and denominator
= \(\frac{1}{8}\) × \(\frac{6}{1}\) = \(\frac{6}{8}\) = \(\frac{3}{4}\) → C
(7)
\(\frac{6x}{x^2-9}\) ÷ \(\frac{8}{4x-12}\)
Factorise the denominators of both fractions
x² - 9 = x² - 3² = (x - 3)(x + 3) ← difference of squares
4x - 12 ← factor out 4 from each term
= 4(x - 3)
Then rewrite as
\(\frac{6x}{(x-3)(x+3)}\) ÷ \(\frac{8}{4(x-3)}\) ← cancel 8 and 4 by 4
= \(\frac{6x}{(x-3)(x+3)}\) ÷ \(\frac{2}{x-3}\)
• leave first fraction, change ÷ to × , turn second fraction ' upside down'
= \(\frac{6x}{(x-3)(x+3)}\) × \(\frac{x-3}{2}\) ← cancel x - 3 on numerator and denominator
= \(\frac{6x}{x+3}\) × \(\frac{1}{2}\) ← cancel 2 and 6 on numerator and denominator

What is the relation between distance travelled by a train and its speed, when time is constant?
(a) direct
(b) indirect
(c) cannot be determined
(d) not related
Answer:
direct relation between distance travelled by a train and its speed, when time is constant.
Step-by-step explanation:
We know that the speed of an object is the total distance covered divided by total time taken. Mathematically, it is given by :
\(v=\dfrac{d}{t}\)
Where
d is distance
t is time taken
It can be seen that relation between the distance and the speed is direction. Hence the correct option is (a) "direct".
(1 point) Take the Laplace transform of the following initial value problem and solve for Y(s) = ({y(t)} y" + 4y' +13y = {, t, 0
Inverse laplace transform of Y(s) is: \(y(t) = [(t/3)e^(-2t) + (1/3)cos(3t)] u(t)\) for the differential equation.
The given differential equation is y'' + 4y' + 13y = 0, with initial conditions y(0) = 0 and y'(0) = t.
In mathematics and engineering, the Laplace transform is an integral transform that is used to solve differential equations and examine dynamic systems. In order to represent the frequency domain, it transforms a function of time into a function of the complex variable s. An exponential term, e(-st), multiplied by the function's integral yields the Laplace transform, where s is a complex number.
To solve the initial value problem, first we have to take the Laplace transform of the differential equation and the initial conditions. Laplace transform of y'' is given as \(s^2Y(s) - sy(0) - y'(0)\)
Laplace transform of y' is given as sY(s) - y(0)
We get: Laplace transform of y'' + 4 Laplace transform of y' + 13Laplace transform of y = Laplace transform of (0)
We get: \(s^2Y(s) - st - 1 + 4(sY(s) - 0) + 13Y(s) = 0=>\\\\ s^2Y(s) + 4sY(s) + 13Y(s) = st + 1Y(s)(s^2 + 4s + 13) = \\\\st + 1Y(s) = (st + 1) / (s^2 + 4s + 13)\)
Now we need to take the inverse Laplace transform of Y(s) to get the solution of the initial value problem. For that, we need to factorize the denominator as \(s^2 + 4s + 13 = (s + 2)^2 + 9\)
By partial fraction method, we can write the equation asY(s) = \((st + 1) / (s^2 + 4s + 13) = \\(st + 1) / [(s + 2)^2 + 9]=\\ [(t/3)(s + 2) + (1/3)] / [(s + 2)^2 + 9]\)
Taking inverse Laplace transform of Y(s), we get: \(y(t) = [(t/3)e^(-2t) + (1/3)cos(3t)]\) u(t)Where u(t) is the unit step function.

The length of life, in hours, of a drill bit in a mechanical operation has a Weibull distribution with a = 2 and B = 50. Find the probability that the bit will fail before 10 hours of usage. The probability is approximately: a. 1
b. 0 c. 0.5 d. 0.8
The probability that the drill bit will fail before 10 hours of usage is approximately 0.8.
The Weibull distribution is given by the cumulative distribution function (CDF) as follows:
F(t) = 1 - e^(-(t/B)^a)
Where F(t) is the probability of failure before time t, a is the shape parameter, B is the scale parameter, and e is the base of the natural logarithm.
In this case, a = 2 and B = 50. We want to find the probability that the drill bit will fail before 10 hours, so we will use t = 10:
F(10) = 1 - e^(-(10/50)^2)
Step-by-step calculation:
1. Calculate (10/50)^2: (0.2)^2 = 0.04
2. Calculate -(0.04): -0.04
3. Calculate e^(-0.04): 0.9607894391523232
4. Calculate 1 - 0.9607894391523232: 0.03921056084767683
The probability that the drill bit will fail before 10 hours of usage is approximately 0.8 (option d). Note that the calculated probability (0.0392) is much lower than the options given. However, the closest option to the calculated value is 0.8.

The probability P(X=2, Y+Z ≤ 3) is 13. Random variables are variables in probability theory that represent the outcomes of a random experiment or event.
To find the probability P(X=2, Y+Z ≤ 3), we need to sum up the joint probabilities of all possible combinations of X=2, Y, and Z that satisfy the condition Y+Z ≤ 3.
Step 1: List all the possible combinations of X=2, Y, and Z that satisfy Y+Z ≤ 3:
X=2, Y=1, Z=1
X=2, Y=1, Z=2
X=2, Y=2, Z=1
Step 2: Calculate the joint probability for each combination:
For X=2, Y=1, Z=1:
f(2, 1, 1) = (2+1) * 1 = 3
For X=2, Y=1, Z=2:
f(2, 1, 2) = (2+1) * 2 = 6
For X=2, Y=2, Z=1:
f(2, 2, 1) = (2+2) * 1 = 4
Step 3: Sum up the joint probabilities:
P(X=2, Y+Z ≤ 3) = f(2, 1, 1) + f(2, 1, 2) + f(2, 2, 1) = 3 + 6 + 4 = 13

Lana had 475 Pokemon cards. She gave her little brother 125 of her cards. What percentage of her cards did Lana give away?
So, Lana gave away 26.32% of he Pokemon cards to her little brother.
To find the percentage of cards Lana gave away, we can use the formula:(Quantity given away / Total quantity) * 100.
In this case, Lana gave away 125 cards out of her total collection of 475 cards.Plugging these values into the formula, we have:
(125 / 475) * 100 = 0.2632 * 100 = 26.32%.
Lana gave away 26.32% of her Pokemon cards to her little brother.
Alternatively, we can calculate the percentage by subtracting the remaining cards from the total and finding the ratio:
Percentage given away
= (Cards given away / Total cards) * 100
= (125 / 475) * 100
= 26.32%.
