While traveling to Europe, Phelan exchanged 250 US dollars for euros. He spent 150 euros on his trip. After returning to the United States he converts his money back to US dollars. How much of the original 250 US dollars does Phelan now have? Round to the nearest cent.
1 European euro = 1.3687 US dollars
44.70 US dollars
73.06 US dollars
136.87 US dollars
140.41 US dollars

[Right Triangles Only] sin∅ = opposite over hypotenuse [Right Triangles Only] cos∅ = adjacent over hypotenuseStep-by-step explanation:
Step 1: Define
We are given a right triangle. We can use trig to solve for the missing side length.
Step 2: Set up ratios
We can choose between the 2 angles and have multiple ratios to solve for x.
sin33° = x/51
cos57° = x/51
Hence, we see that the 1st option would be the correct answer.

Round final answer to the nearest whole degree.
Angle =
Answer:
α = 164.5387822595581°
Step-by-step explanation:
Calculate dot product:
a · b = ax · bx + ay · by = 5 · (-7) + (-4) · 3 = - 35 - 12 = -47
Calculate magnitude of a vector:
|a| = ax2 + ay2 = 52 + (-4)2 = 25 + 16 = 41
|b| = bx2 + by2 = (-7)2 + 32 = 49 + 9 = 58
Calculate angle between vectors:
cos α = a · b
|a|·|b|
cos α = -47
41 · 58
= - 47
2378
√2378 ≈ -0.9638111202541978
α = 164.5387822595581°
Lin and Han's families provide money for their school lunch accounts.
• Han starts with $100 in his account. He spends $15 each week on lunches.
• Lin starts with $25 in her account and does not spend any of it. Her family adds $10 each
week to her account.
1. At the end of 4 weeks, who has more money in their account?
2. After how many weeks will Han and Lin have the same amount of money in their lunch
accounts?
Answer:
1. Lin
2. 3 weeks
Step-by-step explanation:
Lin has more money in his account, and after 3 weeks Han and Lin will have the same amount of money in their lunch accounts.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
Han starts with $100 in his account. He spends $15 each week on lunches.
Lin starts with $25 in her account and does not spend any of it. Her family adds $10 each week to her account.
For hen:
x be the number of weeks
Total amount left = 100 - 15x
Plug x = 4
Total amount left = $40
For Lin:
y be the number of weeks.
Total amount = 25 + 10y
Plug y = 4
Total amount = 25+40 = $65
Lin has more money in his account.
To have the same amount:
100 - 15x = 25 + 10y
x = y
100 - 15x = 25 + 10x
x = 3 weeks
Thus, Lin has more money in his account, and after 3 weeks Han and Lin will have the same amount of money in their lunch accounts.

Keenan hiked 15 times as far as Margot. How far did Keenan hike? the total number of miles be m
The Keenan hike is measured in m is [tex]\frac{15m}{16}[/tex]miles.
The given parameters;
Keenan and Margot hiked m miles altogether.
Let the distance Margot hiked = n
Then, the distance Keenan hiked = 15n
The combined distance both hiked: m = n + 15n
Calculating Margot's hiked distance in terms of m is as follows:
m = n + 15n
m = 16n
n=[tex]\frac{m}{16}[/tex]
The calculation for Keenan's hike in terms of miles is

vegetable ghee is stored in the cylindrical vessel of internal radius 1.4m height 1.5m. if it is transferred into the rectangular tin cans 33cm * 10cm*5cm how many cans are required to empty the vessel
Answer:
5,598 cans are required to empty the vessel
Step-by-step explanation:
The volume of a cylinder of radius r and height h is:
[tex]V = \pi r^2h[/tex]
The volume of a box of dimensions X, Y, and Z is:
V=X.Y.Z
A cylinder of r=1.4 m and height h=1.5 is used to store vegetable ghee. It contains a volume of:
[tex]V_1 = \pi 1.4^2*1.5[/tex]
[tex]V_1=9.236\ m^3[/tex]
Converting to cubic cm:
[tex]V_1=9.236*1,000,000\ cm^3[/tex]
[tex]V_1=9,236,282\ cm^3[/tex]
The volume of each rectangular tin can is:
[tex]V_2=33*10*5=1,650\ cm^3[/tex]
[tex]V_2=1,650\ cm^3[/tex]
The number of cans required to empty the vessel is:
[tex]V_1/V_2=9,236,282/1,650 = 5,598[/tex]
5,598 cans are required to empty the vessel

At 10 m tall farmhouse is located 28.0 metres away from a tree with a an Eagles nest. The angle of the elevation from the roof of the farmhouse to the Eagles nest is 30
What is the height of the Eagles nest?
A 16m
B 24m
C 26m
D 48m
Answer:
26m
Step-by-step explanation:
opp represents the height of the nest from the angle of elevation,adj represents the distance of the farmhouse from the building . Therefore,according to Tan rule (TOA)
Tan30° = opp/adj
opp= tan30° x adj
opp= tan30° x adj
opp = 0.5774 x 28
0pp= 16.12m
the height of the eagle's nest from the ground = 16m + 10m(since the farm house is 10m tall)
the height ...= 26m

16 and what other number is the geometric mean of 32
Answer:
16 and 64
Step-by-step explanation:
The geometric mean n of two numbers a and b can be given as;
√ab = n
In this question;
a = 16
b = ?
n = 32
So we have
16 * b = 32^2
b = 32^2/16
b = (32 * 32)/16
b = 2 * 32
b = 64

What is the length of the hypotenuse?
C =
miles
Answer:
The hypotenuse is 55 miles
Step-by-step explanation:
Given the sides of a right angle triangle as 33 and 44 miles, we want to get the hypotenuse
Mathematically, by Pythagoras’ theorem, the hypotenuse square is the sum of the squares of the other two sides
So we have;
h^2 = 33^2 + 44^2
h^2 = 3025
h = √3025
h =55 miles

Find the selling price of a suit if a store
paid $140 for it, and it was marked up 80%
over the cost.
Answer:
$252
Step-by-step explanation:
The store paid $140 for the suit. Let's first find the 80% of $140.
$140 x 80% = $112
So now we just need to add $112 to $140.
$140 + $112 = $252
A consistent and dependent system of linear equations has how many solutions?
Answer/Step-by-step explanation:
If a system has at least one solution, it is said to be consistent . If a consistent system has exactly one solution, it is independent . If a consistent system has an infinite number of solutions, it is dependent . When you graph the equations, both equations represent the same line.
the coordinates of 3 points are a(-1, -6), b(3, -12) and c(k, 6). Find the value of k if a, b and c are collinear.
Plz answer quickly and step by step.
Answer:
The value of [tex]k[/tex] is -9.
Step-by-step explanation:
If [tex]A(x,y) = (-1,-6)[/tex], [tex]B(x,y) =(3, -12)[/tex] and [tex]C(x,y) = (k,6)[/tex], then [tex]\overrightarrow{BC} = \alpha\cdot \overrightarrow{BA}[/tex]. By vectors sum, we find each vector below:
[tex]\overrightarrow{BA} = A(x,y)-B(x,y)[/tex] (1)
[tex]\overrightarrow{BA} = (-1,-6)-(3,-12)[/tex]
[tex]\overrightarrow{BA} = (-4, 6)[/tex]
[tex]\overrightarrow{BC} = C(x,y)-B(x,y)[/tex] (2)
[tex]\overrightarrow{BC} = (k,6)-(3,-12)[/tex]
[tex]\overrightarrow{BC} = (k-3, 18)[/tex]
By substituting in the equation defined at the begining of this answer:
[tex](k-3, 18) =\alpha\cdot (-4, 6)[/tex]
[tex](k-3, 18) = (-4\cdot \alpha, 6\cdot \alpha)[/tex] (3)
The value of [tex]\alpha[/tex] is:
[tex]6\cdot \alpha = 18[/tex] (3a)
[tex]\alpha = 3[/tex]
If we know that [tex]\alpha = 3[/tex], then the value of [tex]k[/tex] is:
[tex]k-3 = -4\cdot \alpha[/tex]
[tex]k = 3-4\cdot \alpha[/tex]
[tex]k = 3-4\cdot (3)[/tex]
[tex]k = 3-12[/tex]
[tex]k = -9[/tex]
Then, the value of [tex]k[/tex] is -9.
