Q2:

This answer should be Vertical Angles.

Vertical angles are angles that are opposite of each other when two lines cross and equal each other. [tex](a^o=b^o)[/tex]

Q3:

A pair of vertical angles is formed when two lines intersect each other at a single point. They are said to be linear if the angles are adjacent after the intersection of the two lines. The sum of the angles of a linear pair is always equal to [tex]180^o[/tex]. Such angles are also known as complementary or supplementary angles.

This way we eliminate the first option because they intersect at a point, but the sum of their angles is not equal to [tex]180[/tex] degrees.Second option is correct.Third option includes vertical angles. So that it is wrong.We see two angles intersecting at a single point and their sum is [tex]180[/tex] degrees. This option is the correct one.We see two right angles. This is also a correct option.

The answer is [tex]2^{nd}+4^{th}+5^{th}[/tex]

Q4:

The answer is the first option. Adjacent angles. The rule is simple. If [tex]a+b=90^o[/tex] if they're adjacate angles.

Q5:

The answer is the third option. Supplementary angles. The rule is simple. If [tex]a+b=180^o[/tex] if they're supplementary angles.

Using the sine rule we estimate the value of b to be approximately 4.6 units.

The sine law, often referred to as the sine formula, sine rule, or law of sines, is a trigonometrical equation that connects the lengths of any triangle's sides to its sines.

When just two angles and one side of a triangle are known, the rule of sines can be used in the triangulation process to identify the other sides. When two sides and one of the non-enclosed angles are known, it can also be used. These facts do not always prove the triangle, hence the technique in some of these circumstances provides two reasonable estimates for the enclosed angle (this is known as the ambiguous case).

The sine rule states that [tex]\frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC}[/tex] , where A ,B and C are the three vertices of the triangle and a, b and c are the three side lengths.

Given A = 50° and B = 62 ° and a = 4 .

Now we use the given values to :

[tex]\frac{4}{sin50} =\frac{b}{sin62}[/tex]

or, b = 4.6104...

or , b ≈ 4.6

Hence the length of b is 4.6

Trevor tutors French for $15 and hour and scoops ice cream for $10 an hour. He iS going to work 15 hours

hours

Answers

Inequality - Trevor needs to tutor more than 6 hours in order to make at least $180.

What is inequality?

inequality, A declaration of an order relationship between two numbers or algebraic expressions, such as greater than, greater than or equal to, less than, or less than or equal to. Either questions or theorems can be used to express inequality problems, and both can be solved using methods similar to those used to solve equations. The triangle inequality, for instance, states that the length of the remaining side of a triangle is greater than or equal to the sum of the lengths of any two of its sides. Many of these inequalities, including the Cauchy-Schwarz inequality, are used by mathematical analysis to prove some of its most significant theorems.

Total number of hours = 15

Let the hours spent tutoring French is x

Therefor, hours spent in scooping ice cream = (15-x)

Tutoring French is $15 an hour, total for x hours = 15x

Scooping ice cream is $10 an hour, 10×(15-x)= 150-10x

To make more than $180,

= 15x+ (150-10x)> 180

= 15x+150-10x>180

=15x-10x>180-150

A cylindrical container is to be constructed so that the sum of its height and its diameter is 15 feet.
a) Write an equation relating the height of the cylinder, h, to its radius, r. Solve the equation for h in terms of r.
b) The volume of a cylinder is given V=πr^2h. Use your answer in part A to express the volume of the cylindrical container in terms of r alone. Leave your expression in factored form so that it will be easier to analyze.
c) What are the values of r for which this problem makes sense? Explain.

Answers

From the characteristics of the given cylinder, we have that:

a) The equation is h = 15 - 2r.

b) The volume of the cylinder is of V = πr²(15 - 2r).

c) The values of r should be in the range of 0 < r < 7.5.

What is the volume of a cylinder?

The volume of a cylinder of radius r and height h is given according to the following equation:

V = πr²h.

The sum of the height and the diameter is of 15 feet, hence:

h + d = 15.

The diameter is twice the radius, hence:

h + 2r = 15.

For item a, the solution of h in terms of r is:

h = 15 - 2r.

Hence, in item b, the equation is:

V = πr²h.

V = πr²(15 - 2r).

For item c, there are two constraints, as follows:

r > 0, as the radius of a cylinder cannot be negative nor zero.r < 7.5, as the height must be positive.

Whenever the coefficients with one variable are opposites, the equations are added to eliminate a variable; when the coefficients with one variable are equal, the equations are subtracted to eliminate a variable.

For the given question;

Let the number of pie eaten by Alex be 'a'.

y = x + 6 and 3x - 3y = -18
y = −4x + 11 and −6x + y = 11
y = -2x + 5 and 2x + y = -7

Answers

y = x + 6 and 3x - 3y = -18 will have no solution (parallel lines)

y = −4x + 11 and −6x + y = 11 will have unique solution (intersecting lines)

y = -2x + 5 and 2x + y = -7 will have no solutions (parallel lines)

taking first set of equations,

y = x + 6 and 3x - 3y = -18

rearranging it in the ax+by=c form we get,

x - y = 6

3x - 3y = -18

a1=1, b1= -1, c1= 6

a2=3, b2= -3, c2= -18

now comparing,

1/3 = 1/3 ≠ 6/(-18) 0r -1/3

thus, we get a1/a2=b1/b2≠c1/c2, which satisfies the condition for parallel lines, thus there will be no solution.

taking second set of equations,

y = −4x + 11 and −6x + y = 11

rearranging it in the ax+by=c form we get,

4x+y=11

-6x+y=11

a1=4, b1= 1, c1= 11

a2=-6, b2= 1, c2= 11

4/6 or 2/3≠1/1

thus, we get a1/a2≠b1/b2, which satisfies the condition for intersecting lines, so there will be a unique solution.

taking third set of equations,

y = -2x + 5 and 2x + y = -7

rearranging it in the ax+by=c form we get,

2x+y=5

2x+y=-7

a1=2, b1= 1, c1= 5

a2=2, b2= 1, c2= -7

2/2 or 1/1 =1/1≠ -5/7

thus, we get a1/a2=b1/b2≠c1/c2, which satisfies the condition for parallel lines, thus there will be no solution.

Do the ratios 9 6 and 12 8 form a proportion?

Answers

The ratios 9:6 and 12:8 does not form a proportion, since the products of the two are not equal.

Given we have two ratios:

9:6 and 12:8

An equation in mathematics that shows that two ratios expressed in fraction form are equivalent is known as a proportion. The rule that says a/b= c/d if and only if ad=bc allows us to assess whether two ratios, a: b and c: d, constitute a proportion.

To determine if 9:6 and 12:8 form a proportion, we use the rule of proportion.

That is, 9/12 = 8/6

If only if 9×6=12×8

Therefore,  9×6=54

and 12×8=96

since these two products are not equal, we have that 9:12 and 8:6 do not form a proportion.

He lifted it above his head and, as he slowly lowered his hands again, began to draw the string back.12 By the time the arrow was level with his face, the bow was fully drawn. For a moment that seemed to last an eternity, archer and bow remained utterly still.
