If A=kr² and V=kr³, find the percentage increase in A and V if r is increased by 20%
Answer:
The percentage increase in A is 44%. The percentage increase in V is 72.8%.
Step-by-step explanation:
The easiest way to go about solving this problem is to pick your own numbers and plug them into the given equations.
For example, let's say that k = 5 and that r = 10.
[tex]A=kr^{2}[/tex] ⇒ [tex]A= 5 * 10^{2} =500[/tex]
[tex]V=kr^{3}[/tex] ⇒ [tex]V= 5 * 10^{3}= 5000[/tex]
The question is asking, what is the percentage increase if r is increased by 20%. Our chosen k-value will stay the same but our r-value is going to increase. To find the new value of r, we multiply 10, our current value of r, by 1.2. This gives us a new value for r, which is 12.
[tex]10*1.2=12[/tex]
Now, we are going to plug in our new r-value and our k-value into the given equations. k = 5; new r = 12
[tex]A=kr^{2}[/tex] ⇒ [tex]A=5*12^{2}=720[/tex]
[tex]V=kr^{3}[/tex] ⇒ [tex]V=5*12^{3}=8640[/tex]
Next, we have to calculate the percentage increase in our values of A and V. To do this, we use the following formula:
[tex]Percentage Increase = \frac{final - initial}{initial} * 100[/tex]
Percentage Increase for A
Initial value: 500
Final Value: 720
[tex]Percentage Increase = \frac{720-500}{500} * 100 = 44%[/tex]
Percentage Increase for V
Initial value: 5000
Final Value: 8640
[tex]Percentage Increase= \frac{8640-5000}{5000} *100 = 72.8%[/tex]
The percentage increase for A is 44% and the percentage increase for V is 72.8%.

Diego says a quadrilateral with four congruent sides is always a regular polygon. Mai says it never is one. Do you agree with either of them?
Help please!!!
Answer:
mai is correct
Step-by-step explanation:
a quadrilateral with four congruent sides is never a regular polygon it is a rhombus. hope this helps!
A regular polygon has four congruent sides and four congruent angles.
I do not agree with any of them, because both arguments are incorrect
For a polygon to be a regular polygon, the following conditions must be met
All four sides must be congruentAll four angles must be congruent (90 degrees)Some quadrilaterals with four congruent sides are:
Rhombus, Kite, Square, etc.
A rhombus has four congruent sides, but all four angles are not congruent.
This means that Diego's argument is incorrect
All sides and angles of a square are congruent.
Because Mai says such polygons can never be a regular polygon, then Mai's argument is also wrong.
Hence, I do not agree with any of them.

O 336 square units
O 588 square units
Answer: B
Step-by-step explanation:
It’s 168 because to solve problems for the area of a reduced or enlarged figure, first square the scale factor. Then use the given dimensions to find the area of the original figure. Multiply the square of the scale factor by the area of the original to get the reduced or enlarged figure.

Frank has completed 34 deliveries so far this week. He needs to make 85 deliveries for the week. What percentage of his deliveries has Frank completed?
Answer: 40 percentage of his deliveries has Frank completed
Step-by-step explanation:
Given : Deliveries completed by Frank = 34
Total deliveries = 85
Percentage of deliveries has Frank completed = [tex]\frac{\text {Deliveries completed by Frank}}{\text {Total deliveries}}\times 100[/tex]
Putting in the values:
Percentage of deliveries has Frank completed = [tex]\frac{34}{85}\times 100=40\%[/tex]
Thus 40 percentage of his deliveries has Frank completed

Answer:
No answer is equal to 393,500
Step-by-step explanation:
You can try to solve each question.
0.3935 × 10 -6 = -2.065
39.35 × 10 -4 = 389.5
3.935 × 10 -5 = 34.35
3.935 × 10 +5 = 44.35
None of these equal to 393,500

Explain why angle is considered a defined term in geometry.
Answer:
An angle is considered a defined term in geometry because defined terms are terms that have a formal definition and can be defined using other geometrical terms.
Angle: Two rays that share the same endpoint, however, the rays take off in different directions. The area in the middle of the two rays is the angle measure.

How do i do this. Im mad lost
Answer:
x-int: (8/3, 0)
y-int: (0, -32/3)
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
x-intercept is the x-value when y = 0
y-intercept is the y-value when x = 0
Step 1: Write equation
2x - 1/3 = 1/2y + 5
Step 2: Subtract 5 on both sides
2x - 16/3 = 1/2y
Step 3: Multiply 2 on both sides
4x - 32/3 = y
Step 4: Rewrite
y = 4x - 32/3
Step 5: Find x-int
0 = 4x - 32/3
32/3 = 4x
x = 8/3
(8/3, 0)
Step 6: Find y-int
y = 4(0) - 32/3
y = 0 - 32/3
y = -32/3
(0, -32/3)
