A regular hexagon of side 8 cm is given. the hexagon is devided into 6 congruent triangles . calculate the area of the hexagonal
Answer:
96√3 cm^2
Step-by-step explanation:
half base = 4 cm
height of each triangle = 4√3 cm
Area of each triangle
(8 * 4√3)/2 = 16√3 cm^2
area of the hexagonal = 16√3 * 6 = 96√3 cm^2
Find the height of the triangle.

Answer:
12
Step-by-step explanation:
[tex]y = - x {}^{2} + bx + 10 \\ y = - (x {}^{2} - bx - 10) \\ y = -( (x - \frac{b}{2} ) {}^{2} - \frac{b {}^{2} }{4} - 10) \\ y = - (x - \frac{b}{2} ) {}^{2} + 10 + \frac{b {}^{2} }{4} \\ \\ therefore \: \frac{b}{2} = 6 \\ b = 12[/tex]

Write an equation for the nth term of each geometric sequence:
5, 10, 20, 40,
Answer:
a(n) = 5*2^(n-1)
Step-by-step explanation:
The nth term of a geometric series is given by the relation :
a(n) = ar^(n-1)
Where, a = first term ; r = common ratio ; a(n) = nth term of the series.
Given the series : 5, 10, 20, 40,
First term, a = 5
Common ratio = a2/ a1 = a3/a2
Common ratio = 10/5 = 20/10
Common ratio = 2 = 2
Hence, nth term =
a(n) = 5*2^(n-1)

Answer:
KRM = 44 degrees, MRD = 46 degrees
Step-by-step explanation:
This angle is a right angle so it equals 90 degrees. That means that equations 3g + 29 and 7g + 11 will amount to 90 degrees.
(3g + 29) + (7g + 11) = 90
Combine like terms:
10g + 40 = 90
10g = 50
g = 5
Plug in 5 to both equals (in this case the question only asks for 3g + 29 or KRM):
3(5) + 29 =
15 + 29 =

A. $330,34
B. $12,568.96
C. $47,568.96
D. $13, 568.96
Answer:
I think its C you can hate how much you want if I'm wrong im more of a no tester when I get an answer i check but not online
Step-by-step explanation:
The interest to the bank over the life of the loan is $12568.96 if the Tom and Kathy want to borrow $35,000 in order to build an addition to their home.
What is debt?It is defined as the amount one party needs to pay to another party as the first party borrowed an amount which will credited by the second party. Debt occurs when one party cannot be able to purchase something under normal circumstances.
We know the formula for the monthly payment:
[tex]\rm p = \dfrac{r\times pv}{1-(1+r)^{-n}}[/tex]
r = 5 3/8% = 5.375 = 0.05375
Period of the loan n = 12×12 = 144
Loan amount = $35,000
After calculating, we will get:
Monthly payment = $330.34
Total payment = 330.34×12×12 = $47568.96
Total pay in interest to the bank over the life of the loan:
= $47568.96 - 35000
= $12568.96
Thus, the interest to the bank over the life of the loan is $12568.96 if the Tom and Kathy want to borrow $35,000 in order to build an addition to their home.

The radius of the sphere is approximately 4.2 feet.
What is the volume of the sphere?To find the volume of a specific sphere, we need to know its radius. Once we have the radius, we can plug it into the formula and calculate the volume.
The formula for the volume of a sphere is:
V = (4/3) x π x r^3
where V is the volume of the sphere, r is its radius, and π is a mathematical constant approximately equal to 3.14.
We are given the volume of the sphere, so we can plug it into the formula and solve for the radius:
384 = (4/3) x π x r^3
Dividing both sides by (4/3) x π, we get:
r³ = 384 / ((4/3) x π)
r³ = 72.825
Taking the cube root of both sides, we get:
r ≈ 4.243
The radius of the sphere is approximately 4.2 feet.

simon has a quarter, dime, nickel, and penny in his pocket. He wants to buy a snack at the canteen that costs 40¢. If he pulls out one coin at a time, what is the probability that the first 3 coins that are equal to $0.40?
Answer:
1/4
Step-by-step explanation:
Q=event of pulling a quarter (25 cents)
D=event of pulling a dime (10 cents)
N=event of pulling a nickel (5 cents)
P=event of pulling a penny (1 cent)
Simon needs to pull out the penny last, so that the first three coins add up to $0.40.
We assume the coins are wrapped so it is a random choice.
For the first coin, probability of NOT pulling a penny is 3/4,
similarly, for the second coin, probability of NOT pulling a penny is 2/3,
for the third coin, probability of NOT pulling a penny is 1/2,
For all this to happen, we use the multiplication rule
P(3 coins but no penny) = (3/4*2/3*1/2) = 1/4

Since this is a right triangle we can use the Pythagorean theorem
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
3.4^2 + 6.5^2 = h^2
11.56+42.25=h^2
53.81= h^2
Taking the square root of each side
sqrt(53.81) = sqrt(h^2)
7.335529974=h
Rounding to the nearest tenth
7.3 =h
