Answers

Answer 1

Answer: a. c = 30 + 45h

b. $322.50

Step-by-step explanation:

A. Write a function that can be used to find the total charge, c, Juan will pay when the electrician works, h, hours.

This will be calculated as:

c = 30 + 45h

B. How much will Juan pay if it takes the electrician 6 1/2 hours to complete the job?

Using the expression,

c = 30 + 45h

c = 30 + 45(6 1/2)

c = 30 + 292 1/2

c = 322.50

Therefore, Juan will pay $322.50

The legs of a right triangle measure 8 cm and 6 cm respectively. How long is the longest side of the triangle?

a.12
b.10
c.14
d.11

Answers

Answer:

b. 10

Step-by-step explanation:

Based on the Pythagoras Theorem, the longest side of a right-angled triangle is: [tex]\sqrt{a^{2}+b^{2} }[/tex] where a and b are the legs of the triangle.

Longest side of triangle = [tex]\sqrt{8^{2}+6^{2}}[/tex]

                                        = [tex]\sqrt{64+36}[/tex]

                                        = [tex]\sqrt{100}[/tex]

                                        = 10

a. 65,000
b. 60,840
c. 58,500
d. 52,650

Answers

Answer:

a.

65,000

Step-by-step explanation:

There are 65000 possibilities of 4 character-password

What is a password?

A password is a security code that is used for verifying identities

The password has 4 characters.

The password must begin and end with a letter.

So the selections are:

First = 26

Last = 25

The other selections are:

Second = 10 digits

Third = 10 digits

So, the number of password is:

Password = 26 * 10 * 10 * 25

Evaluate

Password = 65000

Hence, there are 65000 possibilities of 4 character-password

Answers

Answer:

x = 30

Step-by-step explanation:

As we know, the angles inside of a triangle added together all equal 180°, so you would combine 3x + 2x + x = 180°. And then from there you can solve.

3x + 2x + x = 180°

[Combine like terms] 6x = 180°

[Divide 6 from both sides of the equal sign] x = 30°
