Answer:

B.

We know that angle 1 has a measure of 55 degrees

That means angle 2 is 125 degrees

This is because the two angles have to have a sum of 180

So, angle 3 is 55

Angle 4 is 125

Angle 5 is 55

Angle 6 is 125

Angle 7 is 55

Angle 8 is 125

C.

GH 1200

Step-by-step explanation:

Salary = GH6000

Allowances= GH2000

Taxable income = (Salary + Allowances)

Taxable income = GH6000 + GH2000

The best ticket deal are illustrations of linear equations

The ticket system is a better deal to the max ticket

From the complete question, we have the following summary:

Charges = $22 per person

Surcharge = $10 per transaction

Charges = $20 per person

Surcharge = $16 per transaction

Assume there would be only one transaction, the linear equations that represent the ticket deals are:

Ticket System: y = 22x + 10

Max Ticket: y = 20x + 16

The costs of ticket for two people in both deals are:

Ticket System: y = 22*2 + 10 = 54

Max Ticket: y = 20*2 + 16 = 56

By comparison;

54 is less than 56

This means that the ticket system is a better deal to the max ticket

Answer:

Step-by-step explanation:

First find the length of the two equal sides. Use Pythagoras.

c^2 = a^2 + b^2

c = ?

a = 7

b = 1/2 48 = 24

c^2 = 24^2 + 7^2

c^2 = 576 + 49

c^2 = 625                Take the square root of 625

√c^2 = √625

c = 25

Both of the equal sides = 25

Perimeter and answer = 25 + 25 + 48 = 98

Answer: 25 + 25 + 48 = 98

Values which are written in proper scientific notation are:

[tex]-3.5*10^4\\3.5*10^4\\3.5*10^-4[/tex]

What is scientific notation?

A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8.

The given numbers are

[tex]1)-350\\2)-3.5*10^4\\3)0.000350\\4)3.5*10^4\\5)3.5*10^-4\\6)35*10^-5\\7)3500[/tex]

As we can see that every number except first, third, sixth and seventh number has been written according to the definition of scientific notation mentioned above.

Therefore, values which are written in proper scientific notation are:

Step-by-step explanation:

First, let's solve the inequality.

Step 1: Subtract 6 from both sides.

Step 2: Divide both sides by 5.

Now that we know x has to be less than 2.6, we can easily assume the largest integer value that satisfies the inequality is when x = 2

Answer:

22.2 feet

Step-by-step explanation:

Treat the ladder, building, and the ground between the bottom of the ladder and the building as the legs of a right triangle.

Then, you can use the Pythagorean Theorem.

X^2 + Y^2 = Z^2

The ladder is the "diagonal" side, so it is the hypotenuse, Z.

It doesn't particularly matter whether the building is X or Y; the end result will be the same.

Therefore:

(23)^2 + Y^2 = (32)^2

Y^2 = (1024 - 529) = 495

Y = 22.249; rounded to the nearest tenth, 22.2 feet

The correct statements about the given triangle are : All sides have different lengths, The third angle measures 40°, It is an acute triangle.

A polygon with three vertices, angles and sides is called a triangle.

Given is a triangle with angle measures of 60° and 80°,

We need to choose the correct statement from the given options,

Calculating the 3rd angle, let its measure be x,

60° + 80° + x = 180°

x = 40°

Since, all the angles are different therefore, the sides will also be different,

Also, all the angles are less than 90°, therefore, the triangle is an acute triangle,

Hence, the correct statements about the given triangle are : All sides have different lengths, The third angle measures 40°, It is an acute triangle.
