Answer:

C.)-12

Step-by-step explanation:

A sequence is an ordered list of numbers.

One way to define the sequence is by listing the numbers of the sequence.

This list is

a1,a2,a3,a4,a5, ... ,an

Where a1 is the first number of the sequence, a2 is the second number of the sequence , ... , an is the ''nth'' number of the sequence meaning that the sequence has a total of ''n'' numbers.

In this exercise, the sequence is

-4,-2,-12,-14,...

This means that the first number of the sequence is -4 ⇒ a1 = -4

The second number is -2 ⇒ a2 = -2

The third number is -12 ⇒ a3 = -12

The value of a3 in the sequence is -12

The correct option is C.)-12

A student ID number is a letter of the alphabet followed by 2 digits. How many different IDs are possible if the digits can be r

mars1129 [50]

First, there are 26 distinct alphabets and 10 distinct digit numbers.

Then, the first digit of ID has 26 possibilities.

For the rest of 2 digits, the total cases are 10*10 = 100 possibilities.

However, there are 10 cases are repeated when two digits are the same. so you have to subtract it by 10

So answer will be 26 * (100-10) = 23400

Dave walked to his friends house at a rate of 4 mph and returned biking at a rate of 10 mph. If it took him 18 minutes longer to

vesna_86 [32]

Answer:

The total distance of the round trip was 4 miles

Step-by-step explanation:

1. Let's check all the information given to answer the question correctly:

Speed of Dave walking to his friend's house = 4 mph

Speed of Dave biking from his friend's house = 10 mph

Time walking is 18 minutes longer than time biking

2. What was the total distance of the round trip?

Time walking = x

Time biking = x - 18

For solving x, we will use the following equation:

4x = 10 * (x - 18)

4x = 10x - 180

-6x = - 180

x = -180/-6 (Dividing by - 6)

x = 30

Dave walked 30 minutes and biked 12 minutes, now we can calculate the total distance, this way:

30 minutes = 0.5 hours and 12 minutes = 0.2 hours

Total distance = 4 *0.5 + 10 * 0.2

Total distance = 2 + 2

Total distance = 4 miles.
