2C1 × 4C1 = 8 (2C1 for the last digit, 4C1 for the first)

It can be a 3 digit no.

_ _ _

First digit has to be less than 5 to be less than 500, and the last digit has to be even.

1) 2/4 _ 4

2C1 × 3C1 = 6 (2C1 to choose between 2 and 4, 3C1 for the second digit)

2) 1/3 _ 2/4

2C1 × 3C1 × 2C1 = 12 (2C1 to choose between 1 and 3, 3C1 for the second digit, 2C1 to choose between 2 and 4)

Total = 2 + 8 + (6 + 12)

What type of angles are ∠4 and∠6? Question 2 options: adjacent angles alternate exterior angles alternate interior angles corres
lianna [129]

Angles 4 and 6 are called Alternate Exterior Angles

Step-by-step explanation:

Alternate Exterior Angles are a pair of angles on the outer side of the each of two lines but on opposite sides of the transversal.

When we take two parallel lines they will create 8 angles, such as 1,2,3,4,5,6,7 & 8.

In that angle 6 is 65 degrees.

Angles 1,2,3 & $ are in one line and remaining four angles on other line.

So Angles 4 and 6 are alternate exterior angles.

Erica sells magazine subscriptions and makes a flat rate of $5.35 for each subscription she sells. if erica made $42.80 on monda
Dovator [93]

Answer:

c. 34

Step-by-step explanation:

1) Add all the given prices on each day.

= 42.80 + 64.20 + 74.90

= 181.90

2) Set up an equation since we do not know how many magazine subscriptions she sold, but we know how much money she made.

Let x = number of magazine subscriptions sold

5.35x = 181.90

x = \frac{181.90}{5.35}

x = 34
