Answer:
x = 8
y = 8√3
Step-by-step explanation:
sin(30) = 1/2
cos(30) = √3/2
They are rule!!!
sin 30° = x / 16
16 sin 30° = x
x = 16 sin 30°
x = 8
sin 60° = y / 16
16 sin 60° = y
y = 16 sin 60°
y = 13.85640....
y = 13.9 (nearest tenth)

A triangle has sides with lengths of 10, 15, and 6 feet. Find the perimeter of a similar triangle whose shortest side is 7
Answers
Answer:
P = 36 1/6 feet
Step-by-step explanation:
you can create the following proportion:
6 / 7 = 10 / x
cross-multiply:
6x = 70
x = 11 2/3
use the same ratio to write a second proportion to find the last side:
6 / 7 = 15 / x
cross-multiply:
6x = 105
x = 17 1/2
Perimeter = 7 + 11 2/3 + 17 1/2 = 28 7/6 + 7 = 29 1/6 + 7 = 36 1/6 feet

the nth term of a sequence is 3n2-1
the nth term of a different sequence is 30-n2
find the only number in both sequences
Answers
Answer: The common number is 26.
Step-by-step explanation:
We know that the n-th term of a sequence is:
aₙ = 3*n^2 - 1
And the n-th term of another sequence is:
bₙ = 30 - n^2
Remember that in a sequence n is always an integer number.
We want to find a number that belongs to both sequences, then we want to find a pair of integers x and n, such that:
aₙ = bₓ
This is:
3*n^2 - 1 = 30 - x^2
Let's isolate one of the variables, i will isolate n.
3*n^2 = 30 - x^2 + 1 = 31 - x^2
n^2 = (31 - x^2)/3
n = √( (31 - x^2)/3)
Now we can try with different integer values of x, and see if n is also an integer.
if x = 1
n = √( (31 - 1^2)/3) = √10
We know that √10 is not an integer, so we need to try with another value of x.
if x = 2:
n = √( (31 - x^2)/3) = √(27/3) = √9 = 3
Then if we have x= 2, n is also an integer, n = 3.
Then we have:
a₃ = b₂
The common number between both sequences is:
a₃ = 3*(3)^2 - 1 = 26
b₂ = 30 - 2^2 = 26

The first step would be to find how many players do both activties. So we would need to add 3/8 + 4/5.
I think you may now how to add fractions, but I will explain it anyways.
1. Figure out a common denominator, and find the equivlent fraction
2. Add
15/40 + 32/40 = 37/40
Then we need to figure how many members the fraction 37/40 represents.
As the fraction is already out of 40,
it would represent 37 members.
Therefore, 37 members do both activites.

A book costs b dollars and a magazine costs m dollars.
Write an expression for the total cost, in dollars, of 5 books and 3 magazines.
Answers
Answer:
C = 5b + 3m
Step-by-step explanation:
Answer:
5b + 3m
Step-by-step explanation:
If b represents the cost of a book, then 5b will represent the cost of 5 books
If m represents the cost of a magazine, then 3m will represent the cost of 3 magazines.
To create an expression for the total cost, add these terms together:
5b + 3m
So, the expression for the total cost is 5b + 3m

Find m and n if the remainder when 8x^3+mx^2-6x+n if divided by (x-1) and (2x-3) are 2 and 8 respectively
Answers
Answer:
we have:
8x³ + mx² - 6x + n
= 8x³ - 8x² + (m + 8)x²- (m + 8)x + (m + 2)x - (m + 2) + m + 2+ n
= 8x²(x - 1) + (m + 8)x(x - 1) + (m + 2)(x - 1) + (m + n + 2)
= (x - 1)[8x² + (m + 8)x + m + 2] + (m + n + 2)
because the remainder if divided by (x-1) is 2
=> m + n + 2 = 2
⇔ m + n = 0 (1)
we also have:
8x³ + mx² - 6x + n
= 8x³ - 12x² + (m + 12)x² - 3/2.x.(m + 12) + ( 12 + 3/2.m)x - (9/4.m + 18) + n +9/4m + 18
= 4x²(2x - 3) + 1/2.(m + 12)x(2x - 3) + (3/2m + 12).1/2.(2x - 3) + 9/4m + n + 18
= (2x - 3)(4x² + (m + 12)/2.x + 3/4m + 6) + 9/4m + n + 18
because the remainder if divided by (2x - 3) is 8
=> 9/4m + n + 18 = 8
⇔ 9/4m + n = -10 (2)
from (1) and (2), we have:
m + n = 0
9/4m + n = -10
=> m = -8
n = 8

$77 at 16% for 6 months
What is the difference between the total amount in the account if you did simple and compound interest?
Answers
Answer:
$0.231
Step-by-step explanation:
Given data
P= $77
r= 16%
t= 6 months= 0.5 years
For simple interest
A= P(1+rt)
A=77(1+0.16*0.5)
A= 77(1+0.08)
A= 77*1.08
A= $83.16
For compound interest
A=P(1+r)^t
A= 77(1+0.16)^0.5
A= 77(1.16)^0.5
A= 77*1.077
A= $82.929
The difference is
=83.16- 82.929
=$0.231
