Vis inversely proportional to r, when r = 3, V= 10.
Find the constant of proportionality.
For full credit, write a proportion and show work.
[Please help I have been stuck for an hour on this]
Answer:
Constant of proportionality = 30
Example: r = 6, V = 5
Step-by-step explanation:
Inverse proportion: V*r = constant
Given r=3, V=10, constant = V*r = 30
Example:
r = 6, V = 30/6 = 5
Triangle ABC is given by the points A(3, 2), B (4, 4), and C(5, 1). Select True or False for each statement.
Answer:
C. The perimeter of ΔABC is 7.6 units.
Step-by-step explanation:
Triangle ABC is given by the points A(3, 2), B(4, 4), and C(5, 1). Determine if each statement is True or False.
A. The perimeter of ΔABC is 9.9 units.
B. ΔABC is an equilateral triangle.
C. The perimeter of ΔABC is 7.6 units.
Solution:
A triangle is a polygon with three sides and three angles. Types of triangles are isosceles, equilateral, scalene, acute, obtuse and right angled triangle.
The distance between two points (x₁, y₁) and (x₂, y₂) in the coordinate plane is:
[tex]Distance=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]
Given the vertices of triangle ABC as A(3, 2), B(4, 4), and C(5, 1). Therefore we have to calculate the side lengths of the triangle:
[tex]AB=\sqrt{(4-3)^2+(4-2)^2}=\sqrt{1+4}=\sqrt{5} \\\\AC=\sqrt{(5-3)^2+*(1-2)^2}=\sqrt{4+1}=\sqrt{5} \\\\BC=\sqrt{(5-4)^2+(1-4)^2}=\sqrt{1+9}=\sqrt{10}[/tex]
1) Perimeter of the triangle = AB + AC + BC = √5 + √5 + √10 = 7.6 units
2) Since only two sides of the triangle are equal (i.e. AB = AC), hence the triangle is an isosceles triangle.

Alyssa opened a bank account that earns 1.5% simple interest. Over 4 years, she earned $72 in interest. How much money did
she initially deposit into the bank account?
Answer:
1200
Step-by-step explanation:
72/4=$18 interest each year
amount x interest rate = interest
amount x .015 = 18
amount = 18/.015
amount = 1200
Assuming exponential function has a starting value of 360 and a decay rate of 73% write an equation to model the situation
Answer:
a = 360 * 0.27^n
Step-by-step explanation:
a = 360 * (1 - .073)^n
a = 360 * 0.27^n
What is the value of x?
x = [ ? ]
Answer:
Step-by-step explanation:
The tangent to the angle makes an angle of 90° with the radius.
The interior angle of the equilateral triangle is 60, so that leaves 90-60 = 30° for the remaining angle with the tangent.
By the exterior angle theorem, 30°+x° = 60° (interior angle of the equilateral triangle), therefore
x = 60-30 = 30°.
Select the correct answer.
Which statement is true?
find the value of x.
Answer:
139 degrees
Step-by-step explanation:
we only have a central angle here (angle at the center of the circle).
and that angle remains the same along these 2 lines all the way out to the circle arc (and beyond, wherever these 2 lines take us).
so, if there is nothing missing in this graph, then x is the same as the inner angle : 139 degrees

The charity gala will cost $392 if it has 28 attendees. How many attendees can there be, at most, if the budget for the charity gala is $812? Solve using unit rates.
I know the answer but m e h.
Answer:
58 attendees
Step-by-step explanation:
Find the unit rate
cost $392 if it has 28 attendees
392/28 = $14 per attendee
How many attendees can there be,if the budget is $812?
812/14 = 58 attendees
How can I solve for y and what is the answer
Answer:
y = 38
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Consider the angles in the large outer triangle, then
x + 46 + 78 = 180
x + 124 = 180 ( subtract 124 from both sides )
x = 56
Consider the 3 angles in the smaller inner triangle, then
y + x + 86 = 180 , that is
y + 56 + 86 = 180
y + 142 = 180 ( subtract 142 from both sides )
y = 38

Step-by-step explanation:
Given

Required
Expression to solve c
To solve for c, we simply calculate the sine of angle at B
i.e.
[tex]\sin(50^o) = \frac{Opposite}{Hypotenuse}[/tex]
This gives:
[tex]\sin(50^o) = \frac{3}{c}[/tex]
Make c the subject

What is the area of this polygon?
___ units2
If you can please explain with you answer!! Thank you so much!
Answer:
39 units
Step-by-step explanation:
area of polygon = area of rectangle VERD + area of triangle MVR
[length of rectangle (6) * width of rectangle (5)] + [1/2 * 3 (height of triangle) * 6 (height of triangle)] = area of polygon
(6*5) + (1/2*3*6) = area of polygon
30 + 9 = area of polygon
area of polygon = 39

I believe your answer is:

Here’s why:
We can use inverse operations to solve for 'm'.⸻⸻⸻⸻
[tex]\boxed{\text{Solving for 'm':}}\\\\5m+1\leq4\\--------\\\rightarrow 5m + 1 - 1 \leq 4 - 1\\\\\rightarrow 5m\leq3\\\\\rightarrow \frac{5m\leq3}{5}\\\\\rightarrow \boxed{m\leq\frac{3}{5}}[/tex]

Any number that is less than or equal to the value of three-fifths would work.

What is the value of y in the equation 5x + 2y = 20, when x = 0.3?
Answer:
y=9.25
Step-by-step explanation:
5x+2y=20
5(.3)+2y=20
1.5+2y=20
2y=20-1.5
2y=18.5
y=18.5/2
y=9.25
ITS DUE SOON PLEASE HELP ME
Answer:
Step-by-step explanation:
The total amount of students is 240
240(50%) = 120 > 60 so, the first true or false is False
240(5%) = 12 = 12 so, the the second true or false is True
240(60%) = 144 = 144 so, the third true or false is True
132 + 12 = 144
A stock loses half its value each week. If the stock started at $125, what is it worth after 4 weeks?
Answer: 7.81
The formula is
y = 125* (1/2)^4
y = 125 / 16
y = 7.81
So at the end of the 4th week, the stock is worth only 7.81 dollars.
If that is not the motive and the first week doesn't count then the formula changes to...
y = 125 * (1/2)^(n-1)
y = 125 * (1/2)^3
y = 15.625 could be the other answer if you looked at it in that perspective
However, I would go with 7.81 as the answer.
Hope I helped :)

An ice cream shop has a sign in their window that says, "We sell 12,000 scoops per month." The number of scoops has been rounded. Which could be the number of scoops sold if they rounded to the nearest thousand? Choose all answers that apply
Answer:
B - 12,111
C - 11,589
Step-by-step explanation:
Here are the options
A - 10, 999
B - 12,111
C - 11,589
In order to round off to the nearest thousand, look at the hundred figure, if the number is greater or equal to 5, add 1 to the thousand figure. If this is not the case, add zero. Replace all the figures before the thousand figure with zero. i.e. the hundred ten, unit
Rounding off 10,999 to the nearest thousand is 11,000
the hundred figure is greater than 5, so one is added to the thousand figure. The
Rounding off 12,111 to the nearest thousand is 12,000
the hundred figure is less than 5, so zero is added to the thousand figure.
Rounding off 11,589 to the nearest thousand is 12,000
the hundred figure is equal to 5, so one is added to the thousand figure.
