Answer:
Tan 0 = 21/29
Step-by-step explanation:
Use the identity sin(2θ) = 2sin(θ)cos(θ)
You have sin(θ) = 20/29
Given that θ is acute (meaning it's in the first quadrant), and, the opposite side is 20 and the hypotenuse is 29, you can calculate the adjacent side with the Pythagorean Theorem as 21. That means the cos(θ) = 21/29.
So sin(2θ) = 2(20/29) = (21/29)

Answer:

Step-by-step explanation:
As we said, points on the coordinate plane are represented as (a, b), where a and b are rational numbers. Rational numbers are numbers that can be written as a fraction, p/q, where p and q are integers. We call a the x-coordinate of the point and we call b the y-coordinate of the point.

Answers
Answer:
10000000000
Step-by-step explanation:
The product of 100,000 multiplied by 100,000 is 10,000,000,000.
To find the product of 100,000 multiplied by 100,000, perform the multiplication operation:
100,000 x 100,000 = 10,000,000,000
The answer is 10,000,000,000.
To explain this, when multiplying two numbers, multiply each digit of one number by each digit of the other number and sum up the results.
In this case, we have:

(4, –1)
(–4, –1)

Answers
Step-by-step explanation:
3x - 4y = 16
-4y = 16 - 3x
y = -(16 - 3x)/4
2x + 3y = 5
2x + -3(16 - 3x)/4 = 5
(8x - 48 + 9x)/4 = 5
17x - 48 = 20
17x = 68
x = 68/17
x = 4
3x - 4y = 16

You have agreed to borrow $50 and after six months you pay back $58. How much interest are you paying? What is the interest rate?
Answers
Answer:
interest: 8 interest rate: 16
Step-by-step explanation:
the interest is 8$ since you payed 8$ extra, the interest rate can be counted in another way but I forgot it. So 50 is 100%, you divide it by 100 and get 0.5. then you take 8/0.5 which means how many percent there is in 8 which is 16.
This can be solved much easier if you multiply by 2. you borrow 100 and get 116 in return. both interest and interest rate is 16
The interest is $8 and rate of interest is 16%.
What is interest?Using the interest rate formula, we get the interest rate, which is the percentage of the principal amount, charged by the lender or bank to the borrower for the use of its assets or money for a specific time period. The interest rate formula is
Interest Rate = (Simple Interest × 100)/(Principal × Time).
Given:
Interest = $58 - $50 = $8
Time = 6 months = 1/2 hours
Principal = $50
rate = ?
Thus, the rate of interest
= 8 x 100 / 50
=800 /50
= 16%
Hence, the interest is $8 and rate of interest is 16%.

Factor out the coefficient of the variable term.
The expression
3/8d + 3/4
Factored is
Answers
Answer:
For this case we have the following expression:
(3/8)d + 3/4(3/8)d+3/4
We must factor the term that accompanies the variable.
We have then:
(3/8) (d + (3/4) * (8/3))(3/8)(d+(3/4)∗(8/3))
Rewriting the expression we have:
(3/8) (d + 8/4) (3/8) (d + 2)(3/8)(d+8/4)(3/8)(d+2)
We're going to check the result. To do this, we multiply the term 3/8 for each term within the parenthesis:
(3/8) d + 2 (3/8)(3/8)d+2(3/8)
Rewriting:
(3/8) d + 3/4(3/8)d+3/4
The factorization is correct.

how to simplify 4a-3b+6a
Answers
Step-by-step explanation:
very simple : the terms with the same base (either a specific number or a variable with the same exponent, or a function ...) can be combined.
4a - 3b + 6a
which terms here have the same base ?
ah, 4a and 6a refer to the same variable (and with the same exponent : 1, as a = a¹).
therefore, I can combine them :
4a + 6a = a×(4+6) = a×10 or simply 10a
so the result is
10a - 3b

Step-by-step explanation: If it doubles every 27 years and its asking if 54 years had passed then it would be 5000*4 which is 20,000
Brainliest is appreciated
Answer: 20,000
Step-by-step explanation:
Because the population doubles every 27 years, the population will double twice since 54/27 = 2
5,000 * 2 = 10,000
10,000 * 2 = 20,000
Alternatively you can add instead of multiplying
5,000 + 5,000 = 10,000
10,000 + 10,000 = 20,000

b-a < c < b+a

find the mean (average) of the data set below? 2/4 18/5 28/10 5/20
Answers

sum of numbers divided by how many numbers there are.
(2/4 + 18/5 + 28/10 + 5/20)/4
we bring all fractions to .../20, as 20 is the smallest common multiple of all denominators. and then we can easily sum them all up.
so,
(10/20 + 72/20 + 56/20 + 5/20)/4 =
143/20 / 4 = 143/20 × 1/4 =

Okay, so he gets up at 7:00. He goes to bed at 10:00. So, 10, into 12 thats two hours and then 7 thats another seven hours, so 9 hours he is in bed. Theres 24 hours in a day so thats 9 hours out of the day. If we turned that into a percentage that would be %62.5 hours in a day he is not sleeping, and 100 - 62.5 would be 37.5.
