What is the area of a rectangle with side lengths of 5 12 foot and 2 3 foot
Answer:
3 2/3ft²
Step-by-step explanation:
Area of a rectangle = Length × Width
Given
Length = 5 1/2 foot
Width = 2/3foot
Substitute
Area of the rectangle = 5 1/2 × 2/3
Area of the rectangle = 11/2×2/3
Area of the rectangle = 22/6
Area of the rectangle = 11/3
Area of the rectangle = 3 2/3ft²
For positive acute angles A and B, it is known that tan A = 35/12 and sin B = 20/29. Find the value of sin(A - B ) in the simplest form.
Answer:
[tex]\displaystyle \sin(A-B)=\frac{495}{1073}[/tex]
Step-by-step explanation:
We are given that:
[tex]\displaystyle \tan(A)=\frac{35}{12}\text{ and } \sin(B)=\frac{20}{29}[/tex]
Where both A and B are positive acute angles.
And we want to find he value of sin(A-B).
Using the first ratio, we can conclude that the opposite side is 35 and the adjacent side is 12.
Then by the Pythagorean Theorem, the hypotenuse is:
[tex]h = \sqrt{35^2 + 12^2} =37[/tex]
Using the second ratio, we can likewise conclude that the opposite side is 20 and the hypotenuse is 29.
Then by the Pythagorean Theorem, the adjacent is:
[tex]a=\sqrt{29^2-20^2}=21[/tex]
Therefore, we can conclude that:
So, for A, the adjacent is 12, opposite is 35, and the hypotenuse is 37.
For B, the adjacent is 21, opposite is 20, and the hypotenuse is 29.
We can rewrite sin(A-B) as:
[tex]\sin(A-B)=\sin(A)\cos(B)-\cos(A)\sin(B)[/tex]
Using the above conclusions, this yields: (Note that since A and B are positive acute angles, all resulting ratios will be positive.)
[tex]\displaystyle \sin(A-B)=\Big(\frac{35}{37}\Big)\Big(\frac{21}{29}\Big)-\Big(\frac{12}{37}\Big)\Big(\frac{20}{29}\Big)[/tex]
Evaluate:
[tex]\displaystyle \sin(A-B)=\frac{735-240}{1073}=\frac{495}{1073}[/tex]
There is a rope hanging from the top of a pole with 3 feet of it lying on the ground. When it is tightly stretched, so that the end just touches the ground, it reaches a point 8 feet from the base of the pole. How long is the rope
Answer:
length of rope [tex](P+3) =12.167[/tex]
Step-by-step explanation:
From the question we are told that
Length of rope on Ground [tex]L_1=3 feet[/tex]
Length of rope from pole base when stretched [tex]L_2=8feet[/tex]
Given length of pole as P
length of the rope is therefore given by
[tex]P+3[/tex]
Generally the Pythagoras theorem is mathematically given by
[tex]P^2+8^2=(P+3)^2[/tex]
[tex]P^2+64=P^2+9[/tex]
[tex]P=9.167[/tex]
Therefore
length of rope [tex]P=9.167[/tex]
length of rope [tex](P+3) =9.167+3[/tex]
length of rope [tex](P+3) =12.167[/tex]

The measure of the angle Z is equivalent to 41.7°.
What is tangent function?The tangent function is one of the main six trigonometric functions and is generally written as tan (x). It is the ratio of the opposite side and the adjacent side of the angle in consideration in a right-angled triangle.Given is a right angle triangle XYZ.
Using the tangent function, we can write -
tan(Z) = XY/XZ
tan(Z) = 25/28
tan(Z) = 0.89
Z = tan⁻¹(0.89)
Z = 41.7°
Therefore, the measure of the angle Z is equivalent to 41.7°.

Suppose a researcher is testing to see if a basketball player can make free throws at a rate higher than the NBA average of 75%. The player is tested by shooting 10 free throws and makes 8 of them. In conducting the related test of significance we have a computer applet do an appropriate simulation, with 1000 repetitions, and produce a null distribution. This distribution represents:_______.
A. Repeated results if the player makes 75% of his shots in the long run.
B. Repeated results if the player makes 80% of his shots in the long run.
C. Repeated results if the player makes more than 75% of his shots in the long run.
D. Repeated results if the player makes more than 80% of his shots in the long run.
E. None of these
Answer: A. Repeated results if the player makes 75% of his shots in the long run.
Step-by-step explanation:
The null distribution is always the opposite of the alternative distribution which in most cases represents the claim or hypothesis which is to be tested or performed. In the scenario given, the challenge is to show that a basketball player has an average higher than that of the NBA. NBA average stands at 75%. The alternative hypothesis is the claim, which is ;
H1 : μ > 75%
THE null is thus :
H0 : μ = 75% ; which means that repeated result of the player will yields an average of 75%

бx — бу = 4
Answer:
the first one is x= 6-3y or if you are going to solve with the y it will be y =2 - x/3
the second one if you are solving for x it will be x= 2/3 + y if you are solving for y it will be x = 2/3 + x
Step-by-step explanation:
hope this helps
x = 6 - 3y....... equation 1
6x -6y = 4
or, 6 (6 - 3y) - 6y = 4
or, 36 - 18y - 6y = 4
or, 36 - 24y = 4
or, 36 - 4 = 24y
or, 32/24 = y
or, 4/3 = y

Jessica is making cookies and brownies for a bake sale. Her recipe for cookies calls for 1 egg per batch, and her recipe for brownies calls for 2 eggs per batch. If Jessica uses 18 eggs and makes 11 batches, how many batches of cookies and brownies did she make?
Answer:
Number of batches of cookies = 4
Number of batches of brownies = 7
Step-by-step explanation:
Let the number of batches of cookies she made = x
And the number of batches of brownies = y
Total number of batches she made = 11
So the equation representing batches will be,
x + y = 11 ---------(1)
Her recipe for cookies calls for eggs = 1 per batch
So eggs required for x batches of cookies = 1 × x = x
Similarly, her recipe for brownies calls for eggs = 2 per batch
So, eggs required for y batches of brownies = 2y
Total number of eggs required = 18
Therefore, equation will be,
x + 2y = 18 ---------- (2)
Equation (2) minus equation (1)
(x + 2y) - (x + y) = 18 - 11
y = 7
From equation (1),
x + 7 = 11
x = 4
Therefore, number of batches of cookies and brownies she made were 4 and 7.

The final cost of a sale item is determined by multiplying the price on the tag by 75%. Which best describes the function that represents the situation?
It is linear because the ratio of the change in the final cost compared to the rate of change in the price tag is constant.
It is linear because the function is continuous.
It is nonlinear because the final cost is determined by multiplying each price tag by 0.75.
It is nonlinear because the price tag and final cost columns do not have the same common difference
Answer:
It is linear because the ratio of the change in the final cost compared to the rate of change in the price tag is constant.
The statement 'it is linear because the ratio of the change in the final cost compared to the rate of change in the price tag is constant' describes this case.
What is the ratio of the change?The ratio of the change is the value that one values changes depending on the corresponding change suffered by another variable.
In this case, the ratio of the change is linear because both variables are directly (proportionally) related and determine a constant equation.
In conclusion, the statement 'it is linear because the ratio of the change in the final cost compared to the rate of change in the price tag is constant' describes this case.

A. How many feet a boards should he buy? Explains.
B. if you can only buy 8-fot boards, how many should he buy? explain
Answer:
Step-by-step explanation:
1 foot = 12 inches
47.5 inches × (1 foot)/(12 inches) = (47.5/12) feet
24 boards × ((47.5/12) feet)/board = 95 feet
:::::
(8 feet)/board × (12 inches)/foot = (96 inches)/board
96/47.5 = 2 remainder 1
An 8-foot board provides two 47.5" boards, with an inch wasted.
He needs to buy 12 of the 8-foot boards.
