When traveling to Great Britain, Bethany exchanged $635 US dollars into £580 British pounds. How many pounds did she receive for each US dollar?
After the exchange from the U.S dollar to British pounds, Bethany received £0.91 for each U.S. dollar.
What is an exchange rate?An exchange rate is a rate or a price of one country's currency in terms of another.
The exchange rate describes how much each currency can be obtained when converting one currency to another.
In this instance, the exchange rate between the U.S. dollar and the British pound is $1 = £0.91.
Data and Calculations:Total US dollars with Bethany = $635
The total British pounds received by Bethany after the exchange = £580
Exchange rate per U.S. dollar = £0.91 (£580/$635)
Exchange rate per British pound = $1.095 ($635/£580)
Thus, Bethany received £0.91 for each U.S. dollar.

twenty more than a number is less than twice the same number
Answer:
x+20<2x
Step-by-step explanation:
20 more than a number implies that twenty must be added to the variable. Then, because it says less than you add a less than symbol. Finally, twice the same number tells you to use x again but since it’s being multiplied by 2, typing 2x makes it easier to understand.
Find seven ordered pairs to the equation y=x²-2. Then determine its graph.
X
-3
The graph of y = x² -2 is a parabola
To find the seven ordered pairs of the equation y = x²-2, we have to find out the value of y by assuming the different values of x that are 0,1,-1,2,-2,3 and -3which gives us seven different coordinates
Let put x=0, y= -2
Let put x=1, y= -1
Let put x=-1, y= -1
Let put x=2, y= 2
Let put x=-2, y= 2
Let put x=3, y= 7
Let put x=-3, y= -7
If we plot all the coordinates for the value of x and y (0,-2),(1,-1),(-1,1),(2,2),(-2,2)(3,-7),(-3,7) and connect all the dots we will get a upward facing parabola
Hence, The graph of y = x² -2 is a parabola

You want to buy an item that costs $100. Which of these is the most cost-effective choice for buying the item?
The most cost-effective choice for buying the item is buying it at a 10 percent discount without sales tax.
A percent discount on a product means that the price of the product is reduced by that percentage.
The full question is that, You want to buy an item that costs $100. Which of these is the most cost-effective choice for buying the item?.
a. using a paid membership card to buy it at a 10 percent discount.
b. buying it online at a 10 percent discount with a $5 shipping charge.
c. buying it at a 10 percent discount without sales tax.
we will calculate the final price in each case to analyze the most cost-effective choice,
In in first case, when using a paid membership card to buy it at a 10 percent discount. we get,
10% of $100 = 10/100×100 = $10
cost = $100 - $10 = $90
On top of this $90 there is the charges of the membership card, therefore the price increases. ( price in first case)
In second case, when buying it online at a 10 percent discount with a $5 shipping charge.
100%-10% = 90%
90% of 100 = $90
Cost: $90 + $5 = $95 ( price in second case)
In third case, when buying it at a 10 percent discount without sales tax.
100% - 10% = 90%
90/100 × 100 = $90. ( price in third case which is minimum as compared to rest of the cases)
Therefore, buying the item at a 10 percent discount without sales tax is the most cost effective method since there is no other cost involved.

1. Write a function that describes the area of the water puddle on the floor as a function of its
radius. Use function notation.
The area of the floor water puddle as a function of radius is 6860. The function notation is mgt∆x = (20 0.5t)g4∆t.
What is meant by function notation?Function notation is a method for writing functions that are simple to read and understand. When we use function notation, the independent variable is typically x, and the dependent variable is F. (x).
Therefore,
The bucket moves upward at a rate of 40/10 = 4 meters per minute. If time is measured in minutes, the bucket is x = 4t meters above the ground at time t. Water is dripping out at a rate of 5/10 kg/minute. Because there is initially 20 kg of water in the bucket, there is m = 20 0.5t kg remaining at time t.
Consider the interval of time between t and t + t. During this time, the bucket moves ∆x = 4∆t meters. So the work performed during this interval is
mgt∆x = (20 0.5t)g4∆t,
The bucket is x = 4t meters
and the integral for the total work performed is
[tex]4 g \int_0^{10}(20-0.5 \cdot t) d t \\[/tex]
= [tex]4 g\left(20 t-\left.0.25 t^2\right|_0 ^{10}=700 g=700 \cdot(9.8)=6860\right. \text { joules. }[/tex]
Hence, The area of the floor water puddle as a function of radius is 6860.
The complete question is:
A bucket of water of mass 20 kg is pulled at constant velocity up to a platform 40 meters above the ground. This takes ten minutes during which time 5 kg of water drips out at a steady rate through a hole in the bottom of the bucket. Find the work needed to raise the bucket to the platform

Answer:
A
Step-by-step explanation:
Let's get the answer.
Suppose the question was the distance between 12 and 1. You would write it as 12 - 1 = 11. So you have to pick an answer that looks like this example.
B: is actually 11 12 -1 = 11
C: is 12 +(-1) = 12 - 1 which also gives 11
D: -1 -12 = -13. You are not really really with a distance here. You are combining 2 negative numbers.
So the answer is A.
-12 - (-1) = -12 + 1 = - 11
Which statement is true concerning the vertex and the axis of symmetry of g(x)=5x2−10x?
The true statement concerning the vertex and the axis of symmetry of g(x) = 5x^2 − 10x is that both values are equal
What are quadratic equations?Quadratic equations are second-order polynomial equations and they have the form y = ax^2 + bx + c or y = a(x - h)^2 + k
How to determine the true statement?The equation of the function is given as
g(x) = 5x^2 - 10x
Differentiate the above equation
So, we have
g'(x) = 10x - 10
Set to 0
So, we have
10xx - 10 = 0
Divide through by 10
So, we have
x - 1 = 0
Solve
x = 1

tax is 1.45% of all wages.)
o $660.00
o $740.00
o $890.68
o $11,396.97
Based on the gross pay to the employees of Family Flowers, the employer's share of total Social Security and Medicare taxes for the first quarter is $11,396.97
How to find the social security and medicare tax?First, find the gross pay for all 17 people in the first quarter:
= ( (660 x 14) + (740 x 3)) x 12 weeks in quarter
= (9,240 + 2,220) x 12
= $137,520
The social security tax is paid up to $128,400:
= 6.2% x 128,400
= $7,960.80
The Medicare tax is:
= 1.45% x 137,520
= $1,994.04
