Is Br2 equal to Avogadro's number?
Br₂ does not equal to Avogadro's number. Since bromine is a diatomic element.
What is a diatomic element?
Diatomic molecules—so named because they only contain two atoms of the same or different chemical elements—are molecules that are made up of two atoms. A diatomic molecule is considered to be homonuclear if it contains two atoms of the same element, such as oxygen (O₂) or hydrogen (H₂).
Each bromine molecule consists of 2 atoms of bromine. Br₂ consists of two moles. One mole of bromine consists of 6.02214076 × 10²³ atoms. Thus 2 moles of bromine consist of 2 × 6.02214076 × 10²³ = atoms. Thus Br₂ does not equal to Avogadro's number.

A packet of grass seed can be
used to cover 50m² of lawn.
A circular lawn has a diameter of 20 metres
How many packets of grass
seed must be bought so that the entire lawn can be covered?
Answer:
7 packets of grass seed
Step-by-step explanation:
First, find the area of the circular lawn using the formula, A = [tex]\pi[/tex]r²
If the diameter is 20 meters, the radius is 10 meters.
Plug in 10 as the radius and solve for the area:
A = [tex]\pi[/tex]r²
A = [tex]\pi[/tex](10²)
A = 100[tex]\pi[/tex]
So, the area of the lawn is 100[tex]\pi[/tex] m² or approximately 314.16 m²
Divide this by 50 to find how many packets of grass seed are needed:
314.16/50
= 6.28
Round this up to 7, since we need to have a whole number answer.
So, 7 packets of grass seed have to be bought.

Jesse from Boston goes to his grandpa Isaac in New York by bus at an average speed of 35 mph and it takes him 6 hours. In a while, Jesse and Isaac go back from New York to Boston in Isaac's car at an average speed of 42 mph. How long does Jesse's trip from New York to Boston take?
Answer:
The Average Speed is 48mph
Step-by-step explanation:
I've done this problem before, I wish A+'s upon all that read this answer. take care man!
The time it takes for Jesse to complete his trip from New York to Boston is 5 hours.
How long does Jesse's trip from New York to Boston take?To calculate the time it takes for Jesse's trip from New York to Boston, we need to use the formula: time = distance / speed.
Given that Jesse traveled from Boston to his grandpa Isaac in New York at an average speed of 35 mph, and the trip took him 6 hours, we can determine the distance using the formula: distance = speed × time.
Distance = 35 mph × 6 hours = 210 miles.
Now, for the return trip from New York to Boston, Jesse and Isaac travel at an average speed of 42 mph. To find the time it takes, we divide the distance by the speed:
Time = 210 miles / 42 mph = 5 hours.
Therefore, Jesse's trip from New York to Boston takes 5 hours time.

What is reflex angle class 9?
A reflex angle is an angle which measures more than 180 degrees and less than 360 degrees.
There are different types of angles in geometry, such as obtuse, acute and right angles, which all are under 180 degrees.
Assume, z is an acute or obtuse angle, and r is the reflex angle, then:
z + r = 360
r = 360 - z
Therefore, we can find the related reflex angle(r), if we know the value of the acute or obtuse angle(z).
A reflex angle equals the summation of 180 degrees and any of the primary angles (acute, right and obtuse angles). Therefore,
Reflex angle = 180° + Acute angle
Reflex angle = 180° + Right angle
Reflex angle = 180° + Obtuse angle

Explain the term angles?Whenever two straight lines as well as rays intersect at a single endpoint, an angle is created. The vertex of the an angle is the location where two points come together.
Measure or "the measure of" are indicated by the "m." Consequently, m1 and m2 stand for "the measure for angle one" and "this same measure of angle two," respectively.The total of a triangle's three internal angles is 180 degrees, as stated by the angle sum feature of a triangle.A closed shape with both inner and exterior angles, a triangle is created by three line segments.When the values of the remaining two angles are known, then angle sum property is utilised to determine the measure of an uncertain interior angle.Thus, the measure of angle ABC means, vertex B lies in between A and C, whose value is to be obtained.

The solutions of the quadratic equation 3x² − x + 8 = 0 are as follows;
x = 0.1667 + 1.6245i
x = 0.1667 - 1.6245i
How to solve the given quadratic equation?In Mathematics, the standard form of a quadratic equation is given by this mathematical expression;
ax² + bx + c = 0
Mathematically, the quadratic formula is modeled or represented by this mathematical expression:
[tex]x = \frac{-b\; \pm \;\sqrt{b^2 - 4ac}}{2a}[/tex]
From the information provided above, we can logically deduce the following data values (parameters);
3x² − x + 8 = 0
Where:
a = 3b = -1c = 8Substituting the data values (parameters) into the quadratic formula, we have the following;
[tex]x = \frac{-(-1)\; \pm \;\sqrt{(-1)^2 - 4(3)(8)}}{2(3)}\\\\x = \frac{1\; \pm \;\sqrt{1\; - \;4(3)(8)}}{2(3)}\\\\x = \frac{1\; \pm \;\sqrt{1\; - \;96}}{6}[/tex]
x = (1 ± √95)/6
x = (1 + √95)/6 = 0.1667 + 1.6245i

A line that includes the point (4,1) has a slope of 1 7 . What is its equation in point-slope form?
Answer:

Step-by-step explanation:
The one point form of line also called slope point form is given by
[tex](y-y_1)=m(x-x_1)[/tex]
where (x1, y1) is the point and m is slope
Given: (x1, y1) = (4,1) and m= 17
Substituting these values in above equation to find equation in point-slope form
(y-1)=17(x-4)
y-1 = 17x-68
y = 17x-67

Two people stand on opposite ends of a bridge that crosses a river. Both can see an island located in the river. The angle
formed at the location of the first person is 37' and the angle formed at the second person is 55'. If the bridge is 5280 feet
long, how far is the first person from the island?
Answer:
The first person is about 4327.76 feet away from the island.
Step-by-step explanation:
We can draw a diagram to represent the situation. This is attached below.
Essentially, we want to find the value of x.
We are given that ∠A is 37° and ∠B is 55°.
The interior angles of a triangle must total 180°. Hence:
[tex]m\angle A+m\angle B+m\angle C=180[/tex]
Substitute:
[tex](37)+(55)+m\angle C=180[/tex]
Thus:
[tex]\displaystyle m\angle C=88^\circ[/tex]
We are also given that the length of the bridge is 5,280 feet. Since we want to find x, we can use the Law of Sines:
[tex]\displaystyle \frac{\sin(A)}{a}=\frac{\sin(B)}{b}=\frac{\sin(C)}{c}[/tex]
The variables do not really matter. It is more important that we align the angles with their respective (i.e. opposite) sides.
The respective side to ∠C is AB which measures 5280.
The respective angle to x is ∠B, which is 55°.
Hence:
[tex]\displaystyle \frac{\sin(55)}{x}=\frac{\sin(88)}{5280}[/tex]
Solve for x. Cross-multiply:
[tex]x\sin(88)=5280\sin(55)[/tex]
Thus:
[tex]\displaystyle x=\frac{5280\sin(55)}{\sin(88)}[/tex]
Use a calculator:
[tex]\displaystyle x\approx 4327.76\text{ feet}[/tex]
The first person is about 4327.76 feet away from the island.

The exact value of secθ in simplest radical for is 1.083
What are trigonometric identities?Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.
We are Given θ is an angle in standard position.
Its terminal side passes through the point (12, -5).
To find the exact value of secθ in simplest radical form.
When θ is an angle in standard position and its terminal side passes through the point (x,y), then the exact value of secθ is:
So, we have x = 12 and y = -5 which is in the first quadrant.
Therefore,
r² = x² + y²
r² = ( 12 )² + ( -5 )²
r² = 144 + 25
r² = 169
r = 13

Answer:
area = 289.24 units²
Step-by-step explanation:
divide the polygon into 9 equal triangles
the top angle of a triangle will be 360°/9 = 40°
the sides of a triangles are both 10 units
The base of a triangle is 6.84 units
the height of a triangle is:
cos 20° = height/10
0.9397 = height/10
height = 9.4 units
The area of a triangle = 1/2(6.84)(9.4) = 32.13 units²
the polygon is made from 9 of these triangles, so 9 x 32.13 = 289.24 units²
