Answer:

a.

65,000

Step-by-step explanation:

There are 65000 possibilities of 4 character-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

where a = 8

           b = 15

           c = s (which is unknown)

plugin values into the formula:

a² + b² = c²

8² + 15² = s²

s = √(64 + 225)

s = √289

s = 17

Answer:

3 batches of cookies

Step-by-step explanation:

Bank. A recipe for one batch of cookies calls for 5 cups of flour and 2 teaspoons of vanilla.

How many batches can you make with 15 cups of flour and 6 teaspoons of vanilla?

We can calculate the batches using either cups of flour or number of teaspoons.

For flour

5 cups of flour = 1 batch of cookies

15 cups of flour = x

Cross Multiply

5x = 15 × 1

x = 15/5

x = 3 batches of cookies

For teaspoons of vanilla

2 teaspoons of vanilla = 1 batch of cookies

6 teaspoons of vanilla = x

Cross Multiply

2x = 6 × 1

x = 6/2

x = 3 batches of cookies.

Hence: you can make 3 batches of cookies with 15 cups of flour and 6 teaspoons of vanilla

Answer:

y= -7x+7

Step-by-step explanation:

y= mx+b

y= slope x+ y intercept

The equation of the line having the slope -7 and y-intercept  is 7 is: y = -7x + 7

A straight line's equation is a relationship between its x and y coordinates, and it is written as y = mx + c, where m is the line's slope and c is its y-intercept.

We are given that the slope m is -7,

and the line crosses the y-axis at 7.

so the value of c = 7

Therefore, we can substitute these values into the slope-intercept form to get:

y = -7x + 7

So the equation of the line is y = -7x + 7.

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

Answer:

where is the drawing l don't understand the measurements

Answer:

I need to see the equation to solve it.

Step-by-step explanation:

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°
