Answer:

Step-by-step explanation:

The biggest 6 digit number is 999,999. If it is a multiple of 2, then the largest one is 999,998.

A number that is larger than 199,999 and is a multiple of 2 is 200,000

Every 100,000 there are 50,000 even numbers

so the answer is 349999

I am not very sure about this so if its wrong Im very sorry

Answer: um what do u mean?

The required number next number in the sequence is 27.

Given that,
Sequence = 55, 48, 41,34, the number that comes next in the sequence is to be determined.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

here,
Given sequence,
55, 48, 41, 34
The sequence has a common difference of 7,
When we subtract 7 from the number 34, the next number in the sequence can be calculated,
So.
next number = 34 - 7 = 27

Thus, the required number next in the sequence is 27.

Answer:

Step-by-step explanation:

The formula for doubling time is given as:

P(t) = Po(2)^t/k

Where:

P(t) = Population after time t = 28,284

Po = Initial Population = 20,000

t = time = 3 days

k = doubling time = ?

28,284 = 20,000 × (2)^3/k

Divide both sides by 20,000

28,284/20,000 = 20,000/20,000 × (2)^3/k

1.4142 = (2)^3/k

2^1/2 = (2)^3/k

Divide both sides by 2

1/2 = 3/k

Cross Multiply

k × 1 = 2 × 3

k = 6

Therefore, the doubling time(k) of the bacteria is 6

Answer:

D.$3.95

Step-by-step explanation:

Let us represent

12-ounce cup = x

16-ounce cup = y

A customer orders a round of coffee for her friends.

If she orders two 12-ounce cups and one 16-ounce cup, she will owe the coffee shop $10.75.

Hence:

2x + y = 10.75.....Equation 1

y = 10.75 - 2x

If she orders one 12-ounce cup and two 16-ounce cups, she will owe the coffee shop $11.30.

Hence:

x + 2y = 11.30.....Equation 2

We substitute 10.75 -2x for y in Equation 2

x + 2(10.75 - 2x) = 11.30

x + 21.50 - 4x = 11.30

Collect like terms

x - 4x = 11.30 - 21.50

-3x = -10.20

x = -10.20/-3

x = $3.40

Solving for y

y = 10.75 - 2x

y = 10.75 - 2($3.40)

y = 10.75 - 6.8

y = $3.95

Therefore , 16-ounce cup is represented by y, the cost for a 16-ounce cup of coffee is $3.95

Option D is correct

Answer:

a) The y-intercept is 160. It represents the initial distance Jayden was from his home.

b) The x-intercept is 4. It represents the amount of time taken for Jayden to reach his home.

Step-by-step explanation:

The y-intercept can be found by looking at the value of y when x=0. When x=0, y= 160. Since the x-axis is the amount of time in hours, x=0 would mean the initial time. The x-axis is the number of miles from Jayden's home thus, Jayden was 160 miles away from his home when x=0 hours.

The x-intercept can be found by looking at the x value when y=0. When y=0, x=4. This means that it took Jayden 4 hours to reach home or 4 hours to travel 160miles to his house.

Answer:

You must perform the same operation on both sides of the equation when isolating the variable in order to keep the equation balanced.

Step-by-step explanation:

According to the properties of equality, you must perform the same exact operation to each side of the equation, so you must also subtract from to keep the equation balanced.

Answer:

AG = 10

GD = 5

CD = 12

Step-by-step explanation:

Centroids divide a median (like AD) into two segments that are in a 2:1 ratio. That's the centroid's special power. So if AD is a total of 15 units long, then dividing it into two segments in a 2:1 ratio means the long side is 10 and the short side is half that, or 5, which checks out because 10+5 = 15.

Now you have GD = 5, and you also know that angle GDC is 90 degrees, so you know triangle GDC is a right triangle, which means it obeys the Pythagorean Theorem.

so CD² + GD² = CG²

so CD² + 25 = 169

CD² = 144

CD = 12

Answer:

4 songs

Step-by-step explanation:

Given data,

Adventure play sells mp3 = $18

Charges per song = $3.25

King music sell Mp3 = $23

Charges per song = $2

Let number of songs be Y, then we can calculate by using following method,

Adventure play MP3 cost + charges per song = Kings Music MP3 cost + charges per song

By putting the value, we get

$18 + $3.25 Y = $23 + $2 Y

By solving the equation,

$3.25 Y - $2Y = $23 - $18

$1.25 Y = $5

Y = $5 ÷ $1.25

Y = 4 songs

Hence, for 4 songs the cost be same.
