Answers
Answer:
Step-by-step explanation:
As you can see from the attached picture below, the only figure that is equal to 5 whole units would be the final triangle. That is because it has 2 whole units in the middle, two half units in the top which equal 1 whole unit. And 2 units in each side corner which when combined would equal 2 whole units making it a total of 5. The rest of the shapes either hold more than 5 or less than 5 units. In the picture below, the top 3 shapes hold more than 5 units while the bottom two triangles hold less than 5.

Consider right triangle △ABC below.
Which expressions are equivalent to sin(∠B)?
Choose two answers:
A: tan(∠A)
B: length of side adjacent to ∠A/length of hypotenuse
C: sin(∠A)
D: AC/AB
Answers
Answer:
Khan academy
Step-by-step explanation:
The expressions that are equivalent to sin(∠B) are option (B) length of side adjacent to ∠A/length of hypotenuse and option (D) AC/AB are the correct answers.
What is trigonometry?Trigonometry is mainly concerned with specific functions of angles and their application to calculations. Trigonometry deals with the study of the relationship between the sides of a right-angled triangle and its angles.
For the given situation,
From the diagram,
The right angle is at ∠C, so opposite to that side is hypotenuse.
If we consider angle at ∠B, then the side opposite to that side is opposite side and the other side is adjacent side.
Thus, Sin∠B = [tex]\frac{oppposite}{Hypotenuse}[/tex]
⇒ Sin∠B = [tex]\frac{AC}{AB}[/tex]
From the options, now check which options is equivalent to Sin∠B,
Option (A): tan(∠A)
Now, consider the angle at ∠A,
so, [tex]tan(\angle A)=\frac{oppposite }{adjacent}[/tex]
⇒ [tex]tan(\angle A) =\frac{CB}{AC}[/tex]
Option A is not equivalent to sin(∠B).
Option (B): length of side adjacent to ∠A/length of hypotenuse
⇒ [tex]\frac{AC}{AB}[/tex]
Option B is equivalent to sin(∠B).
Option C: sin(∠A)
[tex]Sin(\angle A)=\frac{CB}{AB}[/tex]
Option C is not equivalent to sin(∠B).
Option D: AC/AB
Option D is equivalent to sin(∠B).
Hence we can conclude that the expressions that are equivalent to sin(∠B) are option (B) length of side adjacent to ∠A/length of hypotenuse and option (D) AC/AB are the correct answers.

Question 3 (10 points) (08.03/08.05 MC) A pair of equations is shown below:
y = 7x - 8
y = 5x – 2
Part A: Explain how you will solve the pair of equations by substitution or elimination. Show all the steps and write the solution. (5 points)
Part B: If the two equations are graphed, at what point will the lines representing the two equations intersect? Explain your answer. (5 points)
Answers
Answer:
part A) rearrange the equations to form simultaneous equations:
y-7x=8
y-5x=-2
now eliminate the y values by minusing the two equations:
(y-7x=8)-(y-5x=-2)
to get:
-2x=-6
x=3
now substitute x into one of the equations to get y:
y=5x-2
y=15-2
y=13
[tex]x = 3 \\ y = 13[/tex]
part B) the lines will intercept at (3, 13)

[tex]\boxed {\boxed {\sf 22a-14b}}[/tex]
Step-by-step explanation:
We are given this expression:
[tex]17a-10b+5a-4b[/tex]
We are asked to simplify. For this expression, we will need to combine like terms. Like terms are terms with the same variable. In this expression, there are 2 variables: a and b. Use the commutative property of addition to move the like terms together.
[tex](17a+5a)+(-10b+ -4b)[/tex]
Add inside the parentheses.
[tex]22a+ (-10b+-4b)[/tex]
A positive next to a negative, like +- becomes a negative.
[tex]22a+ (-10b-4b)[/tex]
[tex]22a+ -14b \\22a-14b[/tex]
The expression 17a-10b+5a-4b is equal to 22a-14b.

The ratio of dogs to cats in the neighborhood was 3 to 7. If a total of 210 dogs and cats were in the neighborhood, how many cats were there? Complete the statement by providing the correct response in number form.
Answers
Answer:
147 cats
Step-by-step explanation
There are 3 dogs/ 7 cats
3x + 7x = 210
10x = 210
210 ÷ 10 = 21
Therefore,
x = 21.
dogs would be 3x (3 x 21) = 63
cats would be 7x (7 x 21) = 147
