Choose all degrees of rotation that will carry the regular pentagon onto itself.
A. 72°
B. 90°
C. 108°
D. 144°
E. 216°
Answers
Answer:
A. 72°
D. 144°
E. 216°
Step-by-step explanation:
I just answered this.
in short : we rotate each vertex on a circle arc. the center of that circle being P.
so, at the end of every 1/5 of the circle arc there is a vertex of the polygon.
therefore, with every 1/5 of a full circle rotation we move the pentagon visually onto itself.
that is starting at
360/5 = 72°
and then every additional 72°
144°
216°
288°
360°
so, A, D and E are correct

The largest appropriate number out of the given options after rounding off is 545(five hundred forty-five).
What is rounding off?
When a number is rounded off, its value is maintained but is brought near to the coming number, simplifying the number. For entire figures as well as numbers at different places of hundreds, knockouts, tenths,etc., it's done. A round number is constantly understood to stand for a value or value near the nominal value expressed in both formal and informal language. When a number is rounded, it's reduced to a simpler value while retaining a significant portion of its original value.
Since the rounding is off to the nearest 100's(hundreds), the smallest number will be in the range of (450, 499) both(two) inclusive.
Since its asking about the smallest(least) number, the number that is the smallest(least) will be 450
For the largest(greatest) number the range may vary between (501, 549) both inclusive
This means that any number rounded to the nearest 100's(hundreds) will be 500
Since it is asking for the largest(greatest) number, the number will be 549
So, both(two) the numbers largest( 549) and the smallest (450) when rounded to the nearest 100's(hundreds) will result in 500.
Hence, the largest appropriate number out of the given option is 545(five hundred forty-five.

An airplane is flying at a speed of 300 mi/h at an altitude of one mile. The plane passes directly above a radar station at time
t = 0.
Answers
The horizontal distance that the plane has flown can be represented as a function of t d(t) = 300t.
What is the distance?Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.
It is given that:
An airplane is flying at a speed of 300 mi/h at an altitude of one mile.
As we know,
From the relation between time-distance-speed
distance = time×speed
Speed = 300 mi/h
let distance be d and time be t
d = 300t
We can write the above equation as:
The horizontal distance that the plane has flown:
d(t) = 300t
Thus, the horizontal distance that the plane has flown can be represented as a function of t d(t) = 300t.

1. The effects of each transaction on the individual items of the accounting equation are as follows:
Cash $70,000 + (40,000) + (15,000) + (500) + 4,000 + (3,275) + 1,800 + (700) + (1,800) = $14,525
Accounts Receivable $2,800 - 1,800 = $1,000
Office Supplies $1,200
Equipment $10,000 + 15,000 + 1,700 = $26,700
Office Suites $40,000
Accounts Payable $1,200 + $1,700 + (700) = $2,200
Capital–L. Lopez $70,000 + 10,000 = $80,000

What is the perimeter of square STUV? HELP PLSSSS
Answers
The perimeter of square STUV is 32.98 units
Calculating perimeterFrom the question, we are to calculate the perimeter of the given square.
To do this, we will determine one side length of the given square
The length of a side is the distance between the two end points
Using the points U and T
U(-7, 9) and T(1, 7)
Using the formula for the distance between two points
d = √(x₂ - x₁)² + (y₂-y₁)²
x₁ = -7
y₁ = 9
x₂ = 1
y₂ = 7
Thus,
The distance, d, between the points is
d = √(1 - -7)² + (7-9)²
d = √(1 +7)² + (-2)²
d = √(8)² + 4
d = √64+ 4
d = √68
d = 8.2462
This means the length of each side of the square is 8.2462 units
l = 8.2462 units
The perimeter, P, of a square is given by
P = 4l
P = 4 × 8.2462
P = 32.9848
P ≈ 32.98 units
Hence, the perimeter of square STUV is 32.98 units

Answers
Answer:
1. The perimeter of the basketball poster is 240.
The perimeter of the football poster is 282.
3. Football poster has the greater perimeter.
Step-by-step explanation:
To find the perimeter of the basketball poster you multiply the given side by 4 since there is 4 sides. So 60 * 4 = 240.
To find the perimeter of the football poster you use the formula 2(l+w). So our l (length) is 86, while our w(width) is 86. So plug it in the formula.
2(55+86)=282.
282 > 240, which means that the football poster has a greater perimeter.

a cheetah has the ability to accelerate quickly in 3 seconds suppose a cheetah could travel 1.5 hours at top speed covering 11 1.9 miles. how far can a cheetah travel in 1 hr?
Answers
The cheetah will travel a distance of 74.6 miles in one hour.
How do you define the relation of speed, time and distance?Any moving object travels a certain distance over time. We can calculate the speed using these two parameters.
We all know that speed equals distance divided by time. The fundamental unit of speed would be meters per second or 'm'/'s'.However, speed can also be expressed in different units, including such meters per minute as well as kilometers per hour. Speed is usually expressed in kilometers per hour. It is critical to remember that all unit symbols are recorded in the singular.The rate of displacement is actually referred to as speed. These three entities are linked by a formula:
Speed = Distance/Time
The time taken by the cheetah to cover the distance of 111.9 miles is 1.5 hour.
Put the values;
Speed = 111.9/1.5
Speed = 74.6 miles/ hour
Therefore, the distance covered by the Cheetah in 1 hour is 74.6 miles.
