Answer: The sum of the exterior angles of a 54-gon should be 360°.
Step-by-step explanation:
A polygon is a closed figure made up of straight lines like triangle (3-gon) , quadrilateral (4-gon) , square(4-gon), pentagon (5-gon) , octagon(8-gon) etc.
The sum of exterior angles of any polygon with n sides ( or n-gon ) is always 360 degrees.
A 54-gon is a polygon with 54 sides.
Therefore , the sum of the exterior angles of a 54-gon should be 360°.

mrs. O'Neill has 9/4 lb of strawberries if each batch of muffins requires 1/2 pound of strawberries how many batches of muffins can she make provide step by step directions
Answer:
1.125 or 9/8 batches of muffins
Step-by-step explanation:
m = 0.5s where m = the amount of muffins and s = the lb of strawberries
m = 0.5(2.25)
m = 1.125 or 9/8 batches of muffins
Answer:
4.5 batchesStep-by-step explanation:
1 batch = 1/2 poundsx batches = 9/4 poundsCross-multiplication:
x*1/2 = 1*9/4x = 9/4*2x = 9/2x = 4.5 batchesAt what interest rate will P20,000 accumulate to P26,080 in 8 years time?
Answer:
Rate of interest = 3.8%
Step-by-step explanation:
Given:
Initial amount p = 20,000
Final amount p + I = 26,080
Number of year t = 8 year
Find:
Rate of interest
Computation:
I = 26,080 - 20,000
I = 6,080
I = PRT
6,080 = (20,0000)(r)(8)
Rate of interest = 3.8%

A 6 ft tall person walks away from a 10 ft lamppost at a constant rate of 3 ft/s. What is the rate (in ft/s) that the tip of the shadow moves away from the pole when the person is 15 ft away from the pole
Answer:
12.5 ft/s
Explanation:
Height of person = 6 ft
height of lamp post = 10 ft
According to the question,
dx / dt = 5 ft/s
Let the rate of tip of the shadow moves away is dy/dt.
According to the diagram
10 / y = 6 / (y - x)
10 y - 10 x = 6 y
y = 2.5 x
Differentiate both sides with respect to t.
dy / dt = 2.5 dx / dt
dy / dt = 2.5 (5) = 12.5 ft /s

Which best describes how to find an equation of the line shown?
A. The slope m is rise over run, so y over x =m. Solve for Y to get y=mx.
B. The slope m is run over rise, so x over y=m. Solve for x=ym.
C. The slope m is run over rise, so x over y=m. Solve for y to get y= x over m.
D. The slope m is rise over run, so x over y=m. Solve for x to get x=ym.
Answer:
AStep-by-step explanation:
m (slope) = rise = y = y₁ - y₁
run x x₁ - x₁
to get y = mx
therefore, the answer to the question is :
A. The slope m is rise over run, so y over x =m.
Solve for y to get y=mx.

Ken made $14,500 in five months at his new job. How much can he make in two years if his pay remains constant?
Answer:
$69,600
Step-by-step explanation:
Figure out how much Ken makes a month by dividing 14500/5.
This gives you $2900.
If Ken makes $2900 a month and there are 24 months in two years, multiply his monthly earnings by 24 months.
$2900 * 24 = $69,600
What is the scale factor of ABC to DEF?
Answer:
The answer is 8.
Step-by-step explanation:
Since you are looking for the scale factor of ABC to DEF the answer is 8 because DEF is 8 times larger than ABC.
The scale factor of ABC to DEF would be 1/3 Thus, the correct option is B.
What is the scale factor?The scale factor states the scale or measurement by which a figure is bigger or smaller than the other figure. The size by which the figure would be reduced or enlarged is called its scale factor.
In a triangle ABC and DEF
The sides are as follows 5 to 15 which is thrice the length of the side in ABC.
4 to 12 which is 3 times the length of the side in ABC.
3 to 9 which is 3 times the length of the side in ABC.
Thus, the scale factor would be 1/3.

Answer:
7 1/2 customers
Step-by-step explanation:
(02.07)A student writes an incorrect step while checking if the sum of the measures of the two remote interior angles of triangle ABC below is equal to the measure of the exterior angle.
A triangle ABC is shown. The base of the triangle extends into a straight line. The angle formed between this straight line and the edge of the triangle is marked as p. The angle adjacent to p is marked as o, and the other two angles inside the triangle are marked as m and n.
Step 1: m∠m + m∠n + m∠o = 180 degrees (sum of angles of a triangle)
Step 2: m∠p − m∠o = 90 degrees (alternate interior angles)
Step 3: Therefore, m∠m + m∠n + m∠o = m∠o + m∠p
Step 4: So, m∠m + m∠n = m∠p
In which step did the student first make a mistake and how can it be corrected?
Step 1; it should be m∠m + m∠n + m∠o = 90 degrees (corresponding angles)
Step 1; it should be m∠m + m∠n + m∠o = 90 degrees (adjacent angles)
Step 2; it should be m∠o + m∠p = 180 degrees (alternate exterior angles)
Step 2; it should be m∠o + m∠p = 180 degrees (supplementary angles)
Answer:
I'm pretty sure it's the last option. Step 2; it should be m<o+m<p=180 degrees (supplementary angles)
Step-by-step explanation:
I think it's the last one since m<o and m<p are supplementary.
