WILL GIVE BRAINLIEST!! In this triangle, what is the value of x? enter your answer, rounded to the nearest tenth, in the box.
Answers
x = 56.5 and rounded to the nearest tenth is still gonna be 56.5 but to the nearest TENS is 60 (Please give brainliest!!)
Step-by-step explanation:
His is a right triangle so you can use SOH CAH TOA :
Sine = opposite/ hypotenuse
Cosine= adjacent/ hypotenuse
Tangent = opposite/ adjacent
here you have the hypotenuse and are looking to solve for the adjacent side to angle measure 28
so you can set this up like this: cos(28)= x/64
now multiply both sides by 64 and you'll get x = 56.5 just make sure your calculator is in degrees not radians

Scott tossed a wad of paper. It landed in
а
the trash can 3 times and missed 2 times.
Based on these results, how many times
would Scott expect the wad of paper to
land in the trash can if he throws it 60
times?
A. 20
B. 36
C. 40
D. 48
Answers
Answer:
36 times.
Step-by-step explanation:
3/5=0.6
2/5=0.4
60*0.6=36
Scott would expect the wad of paper to land in the trash can approximately 36 times out of 60 throws. So, correct option is B.
To calculate the expected number of times the wad of paper would land in the trash can if Scott throws it 60 times, we can use the concept of probability.
Based on the given results, the probability of the wad of paper landing in the trash can is 3 out of 5 times (3 times in the trash can out of a total of 5 throws).
To find the expected number of successful throws (i.e., landing in the trash can) out of 60 throws, we can set up a proportion:
(Probability of success) = (Number of successful throws) / (Total number of throws)
3/5 = x/60
Now, cross-multiply and solve for 'x':
5x = 3 * 60
5x = 180
x = 180 / 5
x = 36
The correct answer is B. 36
This calculation is based on the assumption that the probability remains the same for each throw, which is the case for independent events like tossing a wad of paper.

• It has a 15% annual interest rate.
• The interest is compounded monthly
• The card has $0 minimum payments for the first four years it is active.
The expression that models this situation is P(1 + r/n)^nt, where (1 + r/n) represents the growth factor of the interest rate.

Answers
Answer:
Equation 1: 7x + 2y = 12.8
Equation 2: 6x + 3y = 12
Cost of 1 apple: $1.60
Cost of 1 orange: $0.80
Cost of 1 orange: $Step-by-step explanation:
Let's use the elimination method to solve this
Multiply equation 1 by 3
(7x + 2y = 12.8) x 3 = 21x + 6y = 38.4
Multiply equation 2 by -2
(6x + 3y = 12) x -2 = -12x - 6y = -24
The x terms will cancel each other out
21x + 6y = 38.4
-12x - 6y = -24
9x = 14.4
Divide by sides by 9 to isolate the x variable
9x/9 = 14.4/9
x = 1.6
This means an apple costs $1.60
Plug the new x into one of the original equations to find y; we'll use equation 1
7(1.6) + 2y = 12.8
11.2 + 2y = 12.8
Subtract 11.2 from both sides
11.2 + 2y = 12.8
- 11.2 - 11.2
2y = 1.6
Divide both sides by 2
2y/2 = 1.6/2
y = 0.8
This means an orange costs $0.80

All the real numbers are the domain of the function. Then the range of the function will be [16π, ∞).
What is a function?A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.
The domain means all the possible values of x and the range means all the possible values of y.
The equation that represents the surface area of the paper cup is given below.
S(h) = 4π√(16 + h²)
Where h is the height of the cup.
The graph of the equation is drawn below. Then all the real numbers are the domain of the function.
And the lowest point of the function will be given as,
S(0) = 4π√(16 + 0²)
S(0) = 4π√16
S(0) = 16π
Then the range of the function will be [16π, ∞).
