What is the area of a regular pentagon if its apothem has a length of 4 feet and each side has a length of 5.8 feet?
a 139.2 ft?
b. 58 ft2
C. 116 ft2
d 69.6 ft-
The area of a regular pentagon is 58 ft2. thus option B is correct.
What is apothem?Apothem for a regular polygon is a line segment that originates from the center of the regular polygon and touches the mid of one of the sides of the regular polygon.
It is perpendicular to the regular polygon's side it touches.
Given; An apothem has a length of 4 feet and each side has a length of 5.8 feet.
The area of any regular polygon can be calculated as:
Area = number of sides (n) x 0.5 x length of sides (s) x apothem (a)
Area = 5 x 0.5 x 4 x 5.8
Area = 58
Hence, the area of a regular pentagon is 58 ft2. thus option B is correct.

Answer:
Step-by-step explanation:
From the graph attached,
Coordinates of the vertices of ΔOAB,
O → (0, 0)
A → (2, 4)
B → (5, 0)
If a point (h, k) is rotated 90° counterclockwise about the origin the image point will be,
(h, k) → (-k, h)
By this rule, if triangle OAB is rotated 90° counter clockwise, new vertices will follow the same rule,
O(0, 0) → O'(0, 0)
A(2, 4) → A'(-4, 2)
B(5, 0) → B'(0, 5)
By plotting these points we can get the image triangle.
The scale drawing of a rectangular room has a length of 18 inches and a width of 12 inches. If the scale for the
drawing is 1 inch = 2 1/2 feet, what is the perimeter of the actual room?
Step-by-step explanation:
Scale factor =5/2
length=5/2×18= 45
width=5/2×12= 30
perimeter = 2(L+W)
=(45×2+30×2)
90 +60
=150 inches

*PLEASE HELP ME* (math attachment) IT'S PAST MIDNIGHT I'M TIRED AND DESPERATE
D
Step-by-step explanation:let's rewrite this
x + y = 11 - equation 1
- x = - y - 9 - equation 2
solve the first equation for x
x + y = 11 (add -y to both sides to get x by itself)
x = -y + 11 - equation 3
now substitute -y + 11 for x in the second equation
y - 11 = - y - 9 (2 negative signs next to each other equals positive)
2y - 11 = -9 (add y to both sides)
2y = 2 (add 11 to both sides)
y = 1 (divide both sides by 2)
now substitute y = 1 into equation 3
x = -1 + 11
x = 10
therefore, x = 10 and y = 1. in coordinates, x goes before y
therefore, the coordinates are (10, 1)
therefore the answer is D
good luck my friend! hope this helped a lot! also, i found a website if you don't fully understand this, its called MathPapa, i didn't use it to work this out so my working might be different but it definitely helps me sometimes. for an equation like this, type it likes this: x+y=11; -x=-y-9

Find the probability of rolling a 5 or greater on the first die and a 2 or greater on the second die
Answer:
The probability is 1/9
Step-by-step explanation:
The probability of rolling a 5 the first time is 1/6
The probability of rolling a number greater than 2
Numbers greater than 2 are 3, 4, 5, 6
So the probability of rolling a number out of these four is 4/6
So the probability of rolling a five for the first time and the probability of rolling a number greater than 2 the second time will be
1/6 * 4/6 = 4/36 = 1/9
Answer:
1/3, 5/6, and 5/18.
Step-by-step explanation:
If a die has 6 sides, then because there are 2 sides equal or greater than 5 (5 and 6), then there is a 2/6 or 1/3 chance of rolling the first die. On the second roll, there are 4 sides equal or greater than 5 (2, 3, 4, 5, and 6), so there is a 5/6 chance of rolling it. To find the probability of both happening, multiply 1/3 by 5/6 to get 5/18.

Multiply the width by the height:
6 2/3 x 2 4/5 = 18 2/3 square feet.
Now divide the volume by that number:
210 / 18 2/3 = 11 1/4
The length of the tank is 11 1/4 feet

The formula for finding the volume of a cone is V=
nur?n. The radius of a cone is 5 cm and the height of a cone is 10
cm. What is the approximate volume of the cone?
Answer:
261.8 cm^3
Step-by-step explanation:
1) find the base area
base area = radius^2 x pi = 5^2 x pi = 25 x pi = 78,539816 cm^2
2) find the volume
V = (base area x height)/3 = (78.539816 x 10)/3 = 785.3/3 = 261.8 cm^3
