Use the diagram to find the distance WX across the water
Answer:
115m
Step-by-step explanation:
Given
In TriangleXYZ
XZ = 23m
ZY = 19m
In TriangleXVW
WV = 95m
Solution
In Triangles XYZ and XVW
AngleWXV = AngleYXZ as they are Vertically Opposite Angles
AngleXWV = AngleXZY as they are Alternate Angles
Therefore TriangleXYZ and TriangleXVW are Similar Triangles
So,
XY/XV = YZ/VW = XZ/XW as they are Corresponding Sides of Similar Triangles
So,
XZ/XW = YZ/VW
or
23/XW = 19/95
23/XW = 1/5
XW = 23 × 5
XW = 115m
Therefore the distance WX is 115m
Arunima buys two bouquets for 121. 75 each and candies for2. 25each. If she left with 21. 10,how much money did she have in the beginning
Knowing that two bouquets of flowers and candies are bought, leaving 21.10, the money at the beginning of the purchase is $266.85.
To find out how much money she had in the beginning, we can use the following equation:
Starting money - (bouquets cost + candies cost) = money left
Let's plug in the given values:
Starting money - ((2 x 121.75) + (2.25 x candies)) = 21.10
Simplifying the equation, we get:
Starting money - (243.50 + 2.25 x candies) = 21.10
Now, we can rearrange the equation to solve for the starting money:
Starting money = 21.10 + 243.50 + 2.25 x candies
If we plug in the given values, we get:
Starting money = 21.10 + 243.50 + 2.25 x candies
Starting money = 266.85
Therefore, Arunima had a total of $266.85 in the beginning.

If an aqueduct had a distance of 53 miles, what would the drop (in feet) at the end destination if the slope is 0.1%?
As a result, the drop at the aqueduct's final destination is 279.84 feet.
What is percent?Percent is a term used to represent a part or a fraction of a whole expressed as a value out of 100. The word "percent" comes from the Latin phrase "per centum," which means "per hundred." Percentages are commonly used to express ratios or proportions of quantities, and are denoted using the symbol "%". For example, if a student answers 85 out of 100 questions correctly on a test, their score can be expressed as 85%, which represents the proportion of questions they answered correctly out of the total number of questions.

(b) There are 14 European cities that Rashid would eventually like to visit. On his next vacation, though, he only has time to visit 3 of the cities: one on Monday, one on Tuesday, and one on Wednesday. He is now trying to make a schedule of which city he'll visit on which day. How many different schedules are possible? (Assume that he will not visit a city more than once.)
(a) There are 220 different boxed sets possible.
(b) here are 2184 different schedules possible for Rashid's vacation.
(a)
To calculate the number of different boxed sets possible, use the combination formula. In this case, choose 9 albums out of 12, and the order of the albums in the boxed set doesn't matter.
The number of combinations of n items taken r at a time is given by the formula:
C(n, r) = n! / (r! × (n - r)!)
In this case, to find C(12, 9):
C(12, 9) = 12! / (9! × (12 - 9)!)
C(12, 9) = 12! / (9! × 3!)
C(12, 9) = (12 × 11 × 10) / (3 × 2 × 1)
C(12, 9) = 220
(b)
To calculate the number of different schedules Rashid can make for his vacation, count the number of ways chosen 3 cities out of 14 for each day of the week.
For Monday, choose one city out of 14.
For Tuesday, choose one city out of the remaining 13 .
For Wednesday, choose one city out of the remaining 12 .

Kirk and martin, two experimental physicists, want to change the diameter of a laser beam while keeping its rays propagating parallel
Kirk and martin, two experimental physicists, want to change the diameter of a laser beam while keeping its rays propagating parallel so the value of distance l is l = fs - fa.
In a partly ionized plasma with several species, we investigate the propagation of electromagnetic waves (or incompressible waves with little thermal pressure) through the magnetic field. Due of variances in mass and density, each species responds to and hence influences electromagnetic field disturbances differently.
For the first lens , ray of light from distant object are parallel , so image will formed at the focal length of first lens.
For second lens,
object distance (u) = fa + l
image distance (v) = ∞
By lens formula,
1/v - 1/u = -1/fs
u = fs
fa + l = fs
l = fs - fa
Collisions between all of the species complicate the process even further. Based on a multi-fluid treatment and Faraday's and Ampere's laws, including the displacement current, a linear analysis is used to derive the dispersion relation of parallel propagation covering a wide range of frequencies, from magnetohydrodynamics (MHD) waves to light waves, with an arbitrary combination of multiple positively charged species, negatively charged species, and neutral species.

Josiah invested $96,000 in an account paying an interest rate of 3.5% compounded continuously. Assuming no deposits or withdrawals are made, the value of the account will reach $153,400 after 9 years.
How long would it take, to the nearest year, for the value of the account to reach $153,400?To calculate this, we can use the formula for the future value of a single sum invested with an inverted interest rate compounded continuously.
Future Value = Present Value × (1 + r)n
Where:
Present Value = 96,000r = 3.5% expressed as a decimal, 0.035n = number of yearsWe can solve for n to find out how many years it will take to reach $153,400.
153,400 = 96,000 × (1 + 0.035)n
153,400/96,000 = (1 + 0.035)n
Taking the natural log of both sides and simplifying:

jimmy and amanda are on an archery team . jimmy hits 3 bullseyes in every 20 shots . amanda hits a bull-eye 0n 18 percent of her shots how hit more bull's-eyes more often explain
Answer:
Jimmy hits 3 bullseyes in every 20 shots, which can be written as a fraction: 3/20.
To compare this to Amanda's performance, we need to find out what fraction of Amanda's shots result in a bullseye. We know that Amanda hits a bullseye on 18 percent of her shots, which can be written as a fraction: 18/100 or 9/50.
To determine who hits more bullseyes more often, we can compare the two fractions. We can find a common denominator of 100 to make the comparison easier:
3/20 = 15/100
9/50 = 18/100
Now we can see that Amanda hits a bullseye more often than Jimmy, as 18/100 is a larger fraction than 15/100. In other words, if both Jimmy and Amanda shoot 100 arrows, Amanda is expected to hit more bullseyes than Jimmy.
Answer:
Jimmy
Step-by-step explanation:
To compare who hits more bull's-eyes more often, we need to calculate the probability of hitting a bull's-eye for each person.
Jimmy hits 3 bullseyes in every 20 shots, so the probability of hitting a bull's-eye for Jimmy is:
3/20 = 0.15 or 15%
Amanda hits a bull's-eye on 18 percent of her shots, so the probability of hitting a bull's-eye for Amanda is:
18% = 0.18
Comparing these probabilities, we can see that [Jimmy hits more bull's-eyes more often,] since his probability of hitting a bull's-eye (15%) is greater than Amanda's probability (18%).
It's important to note that this comparison is based solely on the given information about hitting bull's-eyes, and does not necessarily reflect overall performance or skill as an archer. Other factors, such as accuracy, consistency, and technique, may also play a role in determining an archer's success.
Calculate the amount that will be in the bank after 5 years if R4 700 is invested at 5% simple interest
The amount after 5 years with a simple interest of 5 % is A = $ 875
What is Simple Interest?Simple interest is a method of calculating interest that ignores the impact of compounding. While interest frequently compounds throughout the course of a loan's set periods, simple interest does not. Simple interest is calculated by multiplying the principal amount by the interest rate, times the number of periods.
Simple Interest = ( Principal Amount x Rate x Time Period ) / 100
Given data ,
Let the amount in the bank after 5 years be A
Let the simple interest be represented as I
Now , the principal amount invested = $ 700
The rate of interest r = 5 %
The number of years n = 5 years
Simple Interest = ( Principal Amount x Rate x Time Period ) / 100
On simplifying , we get
Simple Interest I = ( 700 x 5 x 5 ) / 100
Simple Interest I = 25 x 7
Simple Interest I = $ 175
Now , the amount after 5 years = P + I = 700 + 175

A landowner recently sold a large plot of land. The sale decreased his total acreage by 12%. Let v be the original acreage. A. Write two equivalent expressions that represent the new acreage. B. Use the expressions to describe another way to find the new acreage
A. Two equivalent expressions that represent the new average are x = v - 0.12v and x = 0.88v.
B. Another way to find the new average directly using:
x = 0.88v (using the second expression )
What is expression ?
In mathematics, an expression is a combination of numbers, symbols, and/or operators that represent a value or a relationship between values. Expressions can be as simple as a single number, variable, or symbol, or they can be complex combinations of terms, functions, and operations.
For example, the expression "2x + 3" is a combination of the number 2, the variable x, and the operators + and *. It represents a relationship between x and a value that is 3 more than twice x.
Expressions can be used in a wide range of mathematical contexts, including algebra, calculus, geometry, and statistics, to name a few. They are an essential tool for describing and solving mathematical problems.
A. Let x be the new acreage after the sale. Then we have:
x = v - 0.12v (12% decrease means 0.12v decrease from v)
x = 0.88v (Simplify by factoring out v)
So, two equivalent expressions that represent the new average are x = v - 0.12v and x = 0.88v.
B. Another way to find the new acreage is to multiply the original acreage by the decimal equivalent of the percent decrease. In this case, the percent decrease is 12%, which is equivalent to 0.12 as a decimal. So, we have:
x = v - 0.12v (using the first expression above)
x = 0.88v (simplify)
x = (1 - 0.12)v (factor out v)
x = 0.88v (simplify)
Alternatively, we can calculate the new average directly using:
x = 0.88v (using the second expression above)
