The compound interest when $7300 when interest is compounded semi annually is $2482.70.
The compound interest when $7300 when interest is compounded monthly is $1972.73.
What is the compound interest?An investment earns compound interest when both the amount invested and the interest accrued increases in value at predetermined time intervals.
The formula to represent compound interest is :
FV - amount invested
FV = P (1 + r)^nm
FV = Future value P = Present value R = interest rate m = number of compoundingN = number of yearsa. 7300 x [1 + (0.1/2)]^(3 x 2) = 9782.70
Compound interest = 9782.70 = 7300 = $2482.70
b. 7300 x [1 + (0.08/12)]^(12 x 3) = 9272.73
9272.73 - 7300 = $1972.73

Answer:
z = 10
Step-by-step explanation:

give brainiest please!
hope this helps :)
Answer:
z = 10
Step-by-step explanation:
Distribute:
(2z + 5) + 5(z + 2) = 10(z - 1)
2z + 10 + 5(z + 2) = 10(z - 1)
and distribute again:
2z + 10 + 5(z + 2) = 10(z - 1)
2z + 10 + 5z +10 = 10(z - 1)
and add the 2 tens that are in bold.
2z + 10 + 5z +10 = 10(z - 1)
2x + 20 + 5z = 10(z-1)
Theres a lot more steps but just
comebine like terms

Stubtract 20 from both sides
simplify
subtract 10z from both sides
simplfy
divide both sides by the same factor

There are 18 students on the debate club. How many ways can the club send 4 students to the next debate
There are 3060 ways the club send 4 students to the next debate if there are 18 students on the debate club.
What is permutation and combination?A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.
We have the total number of students = 18
The number of ways the club send 4 students to the next debate is:

Step-by-step explanation:
Katrina lives directly east of the park. The football field is directly south of the park. The
library sits on the line formed between Katrina's home and the football field at the exact point
where an altitude to the right triangle formed by her home, the park, and the football field
could be drawn. The library is 4 miles from her home. The football field is 18 miles from the
The distance between library and park is 6√2 miles and the distance between park and field is 6√11 miles.
What is Similar Triangle?Similar triangles are the triangles that have corresponding sides in proportion to each other and corresponding angles equal to each other.
Here, mark the park as A, Home as B, Library as C and field as D.
Now, CD = 18 miles
BC = 4 miles
we have to find AC (distance between library and park)
BD = BC + CD = 18 + 4 = 22 miles
Using property of similar triangles,
AD² = BD X CD
AD² = 22 X 18
AD = √22 X √18
AD = 6√11 miles
By Pythagoras theorem,
AD² = AC² + CD²
396 = AC² + 324
AC² = 396 - 324
AC² = 72
AC = √72
AC = 6√2 miles
Thus, the distance between library and park is 6√2 miles and the distance between park and field is 6√11 miles.

10 POINTS, please explain your answer ik so confused about how to get surface areas ty lol
Step-by-step explanation:
since there is triangle , you use the formula
1/2 × b × h
as you can see the base is 6 and the height is 4, so
1/2 × b × h
= 1/2 × 6 × 4
=12
12 × 2 = 24 , you times by 2 because there is 2 triangle
There is also rectangle in the diagram, so you use the formula , length × breadth , the length is 8 and the breadth is 5, so
length x breath
= 5 × 8
=35
35 × 2 = 70 , times by 2 because you can see 2 rectangles with the same length and breadth
length x breath
= 8 × 6
= 48
this one is different because the length is 8 and the breadth is 6.
SA = 48 + 35 + 24

Answer:
Part A:
In order to find a coterminal angle, or angles of the given angle, simply add or subtract 360 degrees of the terminal angle as many times as possible.
Part B:Simply put, coterminal angles start at 0° and end at the same place, though in different directions and multiple times around (you're probably going to want to make that sound a little more formal). Since each time around is 360°, boom
Part C: 75° is in Quadrant II, right? If I go one more time around, 75 + 360 = 435°. I can also go "backward. Starting at 0 and going clockwise, I'm going 75 fewer degrees than all the way around, so 360-75 = 285° but since I'm going "backward" 75 - 360 = -285°. One more is on you.

I need help with this.
Answer:
x= -4, y = 4.
Step-by-step explanation:
first, divide the first equation by its G.C.D (5), to obtain its simplest form.
5x/5 + 5y/5 = 0/5 to obtain x + y = 0.
Then, find the value of y by rearranging the second equation.
y = 36 + 8x. (Rem; when 8x moves to the other side of the equation, it changes the sign)
Now substitute the value of y (36 + 8x) in the first equation which is x + y = 0.
x + 36+8x = 0
Put like terms together.
36 + 9x = 0
move 9x to the other side and change its sign.
36 = -9x
divide both sides by 9,
x = -4.
Lastly, find the value of y by replacing the value of x in either equation.
-8(-4) + y = 36
32 + y = 36
rearrange to obtain
y = 36 - 32
y = 4.

many months will he have to belong to each before the costs are the same?
Answer:
2 months

50 - 40 = 10
25-20 = 5
10/5 = 2
The months for which Joey have to belong to each before the costs are the same are 2 months.
What is equation modelling?
Equation modelling is a method of writing a mathematical relation from a mathematical statement for mathematical analyses of the problem given.
Given is different fees structure of two gyms → Gym A has a $40 sign up fee and it costs $25 per month. Gym B has a $50 sign up fee and costs $20 per month.
Assume that the months for which Joey have to belong to each before the costs are the same be x.
Then -
For Gym A -
Total cost for x months = C[A] = 25x + 40
For Gym B -
Total cost for x months = C[B] = 20x + 50
For same cost -
C[A] = C[B]
25x + 40 = 20x + 50
25x - 20x = 50 - 40
5x = 10
x = 2
Therefore, the months for which Joey have to belong to each before the costs are the same are 2 months.

From his eye, which stands 1.52 meters above the ground, Wyatt measures the angle of elevation to the top of a prominent skyscraper to be 28 degrees. If he is standing at a horizontal distance of 331 meters from the base of the skyscraper, what is the height of the skyscraper? Round your answer to the nearest tenth of a meter if necessary.
The height of the skyscraper is 177.51 m which is 331 m from the base of skyscraper.
What is Trigonometric Ratio?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
Here, h₀ = 1.52 m, angle of elevation = 28⁰
d = 331 m
Now, tan 28⁰ = h/d
h = d. tan 28⁰
h = 331 X 0.5317
h = 175.99 m
Total height = h + h₀
= 175.99 + 1.52
= 177.51 m
Thus, the height of the skyscraper is 177.51 m which is 331 m from the base of skyscraper..

A. x = - 12/9
B. x = - 20/23
C. x = - 20/9
D. x = - 12/23
Answer:
x = -20/9
Step-by-step explanation:
First we need to distribute this equation 4(4x+1) = 3x-4(6-x)+8. After distributing we get 16x+4 = 3x-24+4x+8. Next we add like terms to get 16x+4 = 7x-16. Now subtract 7x on both sides to get 9x+4 = -16. Now subtract -4 on both sides to get 9x = -20. Now divide by 9 on both sides to get x= -20/9.
