Adventure play sells an mp3 for 18.00 and charges $3.25 per song. King music sell a player for $23.00 and charges $2.00. For how many songs will the cost be the same
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.

An extremely handsome math teacher was on a farm and he counted 32 animals; all pigs and chickens. Then he counted the number of feet. The total was 88. Find the number of pigs and the number of chickens. (Hint: You need to take the number of legs each animal has into consideration.)
15 pigs and 17 chickens
12 pigs and 20 chickens
20 pigs and 12 chickens
22 pigs and 10 chickens
Answer:
12 pigs and 20 chickens
Step-by-step explanation:
Chicken = 2 legs
Pig = 4 legs
(15 * 4) + (17 * 2) = 88 NO
(12 * 4) + (20 * 2) = 88 Yes, and 12 + 20 = 32
Decide whether the relation is a function, and give the domain and range.
Consider the following sequence and type the next number in the sequence.
55, 48, 41,34
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.

whats 6x + 7y - 5 when x = 2 and y = 3
Answer:
28
Step-by-step explanation:
Plug into equation
Answer:
Well if x = 2 and y = 3 then that would be 28
Step-by-step explanation:
First replace the x with 2 and multiply it with 6 getting 12 and then do the same with 7y and turn the y into 3 multiply it getting 21 then you add that with the 12 we got and get 33 then subtract it by that 5 and finish with 28!
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. If she orders one 12-ounce cup and two 16-ounce cups, she will owe the coffee shop $11.30. What is the cost for a 16-ounce cup of coffee? A.$3.29 B.$4.25 C.$3.40 D.$3.95
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

A water tank is contaminated with a colony of 20 000 e.Coli bacteria. After 3 days the bacteria has grown to 28 284 e. Coli. What is the doubling time of the bacteria using an equation
Answer:
6
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

How many different numbers could he have picked?
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

Answer:
x = – ⅓
Step-by-step explanation:
The solution to the expression can be obtained as follow:
–3.1x + 7 – 7.4x = 1.5x – 6(x – 3/2)
Clear bracket
–3.1x + 7 – 7.4x = 1.5x – 6x + 9
–3.1x – 7.4x + 7 = –4.5x + 9
–10.5x + 7 = –4.5x + 9
Collect like terms
–10.5x + 4.5x = 9 – 7
–6x = 2
Divide both side by –6
x = 2 / –6
x = – ⅓
Thus, the solution to the equation is –⅓

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
