If all three of them together have a total of 520 kroner then bill would have 205 kroner
amounts of money that Alan, Bill, and Cassie have:
Let A be the amount of money that Alan has.
Let B be the amount of money that Bill has.
Let C be the amount of money that Cassie has.
From the problem, we know that:
A + B = 250 (equation 1)
B + C = 475 (equation 2)
A + B + C = 520 (equation 3)
We want to solve for B, the amount of money that Bill has.
One way to do this is to use equation 1 to solve for A in terms of B:
A = 250 - B
We can then substitute this expression for A into equations 2 and 3:
(250 - B) + B + C = 520
Simplifying this equation, we get:
C = 270
Substituting this value of C into equation 2, we get:
B + 270 = 475
Solving for B, we get:
B = 205
Therefore, Bill has 205 kroner.

Rob's favorite shampoo is available in two sizes: regular and economy. Each size and its price are shown in the table. Size regular economy Quantity (oz) 20 40 Price ($) $8.00 $10. Which size is the better buy?
Answer:
Step-by-step explanation:
To determine which size of shampoo is the better buy, we need to calculate the unit price, which is the price per ounce for each size.
For the regular size, the unit price is:
$8.00 / 20 oz = $0.40/oz
For the economy size, the unit price is:
$10.00 / 40 oz = $0.25/oz
Since the unit price for the economy size is lower than the unit price for the regular size, the economy size is the better buy.
Therefore, the economy size of shampoo is the better buy.

Conve
The required circumference of the given circle is 45.27 cm approx.
What is circumference?In geometry, the perimeter of a circle or ellipse is its circumference. In other words, the circumference would equal the length of the arc if the circle were expanded up and straightened out to a line segment.
The term "perimeter" is most frequently used to describe the radius of any closed shape.
The circumference of a circle is the length around its periphery.
It is similar to the edges of other shapes, including squares.
It can be viewed as the line that defines the shape.
So, calculate the diameter using the Pythagorean theorem as follows:
h² = a² + b²
h² = 8² + 12²
h² = 64 + 144
h² = 208
h = √208
h = 14.42
Now, calculate the circumference as follows:
Radius = 14.42/2 = 7.21
Now,
= 2πr
= 2*3.14*7.21
= 45.2788
Therefore, the required circumference of the given circle is 45.27 cm approx.

Chu rides his bike 1.39 miles from his home to baseball practice. On the way home he takes a shorter route than the route he took to baseball practice. How far does he ride his bicycle from baseball practice to home?
Answer:
We don't know the exact distance Chu takes on his way back, but we do know that it's shorter than the distance he took on the way to baseball practice. Let's call the distance he takes on the way back "x".
We know that the distance he rode to baseball practice was 1.39 miles. So, the total distance he rode is:
1.39 miles + x miles
We can also assume that the total distance he rode going to baseball practice and coming back home is the same. That is:
1.39 miles + x miles = x miles + x miles
Simplifying this equation, we get:
1.39 miles + x miles = 2x miles
Subtracting x miles from both sides, we get:
1.39 miles = x miles
So, Chu rides his bicycle 1.39 miles from baseball practice to home.

Using distance formula, the triangle ABC is a scalene triangle
What is triangle ABCTo classify the triangle, we need to determine whether its sides are equal in length (in which case it's equilateral or isosceles), or whether they are all different lengths (in which case it's scalene). We can use the distance formula to calculate the length of each side of the triangle, as follows:
The distance formula gives us the distance between two points (x1, y1) and (x2, y2) in the coordinate plane:
d = √[(x2 - x1)^2 + (y2 - y1)^2]
Using this formula, we can find the length of each side of triangle ABC:
AB = √[(4-1)^2 + (4-0)^2] = √(9 + 16) = √25 = 5
BC = √[(6-4)^2 + (2-4)^2] = √(4 + 4) = 2√2
AC = √[(6-1)^2 + (2-0)^2] = √(25 + 4) = √29
We can see that AB = 5, BC = 2√2, and AC = √29. Since all three sides have different lengths, the triangle is scalene.
Note that the midpoints of the sides AB and BC are not relevant for determining the type of triangle. Also, it's not accurate to say that the midpoint of AB is (4/3, 2), as the coordinates of the midpoint are actually ((1+4)/2, (0+4)/2) = (2.5, 2), and similarly for the midpoint of BC.

Find the common ratio of the geometric sequence -7, -42, -252,. −7,−42,−252,
the common ratio of the geometeric sequence -7, -42, -252 is 6.
A geometric sequence is a sequence of numbers where each term is obtained by multiplying the previous term by a fixed non-zero constant, called the common ratio. We can find the common ratio (r) of the sequence -7, -42, -252 by dividing any term by its previous term. For example:
-42 / (-7) = 6
-252 / (-42) = 6
Since the ratio is the same for both, we can conclude that the common ratio is 6. Therefore, each term is obtained by multiplying the previous term by 6.
To check, we can multiply any term by 6 to obtain the next term in the sequence. For example:
-7 * 6 = -42
-42 * 6 = -252
So, the common ratio of the sequence -7, -42, -252 is 6.

A person tosses from atop a cliff a people straight downward with an initial velocity of -9. 0 meters per second, after 50 seconds, how far beneath the cliff is the people?
After 50 seconds, the person has fallen approximately 2252.5 meters below the cliff.
Assuming no air resistance, we can use the formula for distance traveled by an object under constant acceleration:
d = v_i * t + (1/2) * a * t²
where d is the distance traveled, v_i is the initial velocity, t is the time, and a is the acceleration.
In this case, the initial velocity is -9.0 m/s (negative since it is downward), and the time is 50 seconds. The acceleration due to gravity is approximately -9.81 m/s².
Substituting the given values into the formula, we get:
d = -9.0 m/s * 50 s + (1/2) * (-9.81 m/s²) * (50 s)²
≈ -2252.5 m

The number of cells in a bacteria colony increases according to the expression t^2-7t-7 with t representing the time in seconds that the colony is allowed to grow in 20°C and t^2-6t-7 when the colony grows at 30°C. After 1 minute, which will be greater in number, a colony at 20°C or 30°C?
Answer:
Step-by-step explanation:
To solve this problem, we need to find the number of cells in each colony after 1 minute (60 seconds) and compare them.
For the colony growing at 20°C, the expression for the number of cells is:
N(20°C) = t^2 - 7t - 7
Substituting t = 60 seconds:
N(20°C) = (60)^2 - 7(60) - 7 = 3533
Therefore, the number of cells in the colony growing at 20°C after 1 minute is 3533.
For the colony growing at 30°C, the expression for the number of cells is:
N(30°C) = t^2 - 6t - 7
Substituting t = 60 seconds:
N(30°C) = (60)^2 - 6(60) - 7 = 3563
Therefore, the number of cells in the colony growing at 30°C after 1 minute is 3563.
Comparing these results, we see that the colony growing at 30°C has a greater number of cells after 1 minute than the colony growing at 20°C. Therefore, the colony growing at 30°C will have a greater number of cells than the colony growing at 20°C after 1 minute.

Simple interest is calculated as $3000 x 2.5% = $76. Compound interest is added to the principal to determine the balance for the next period.
What is simple interest?Simple interest is a type of interest calculation that only takes into account the principal amount of a loan or investment. It does not include any additional payments (or compounding) of the interest. It is calculated by multiplying the principal amount by the interest rate and the number of periods for which the loan is taken out.
For Suzanne's investment, the annual interest rate is [tex]$2.5 %$[/tex], and the interest is simple. Therefore, the interest she earns each year is [tex]$$ I = P \times r = 3000 \times 0.025 = 75. $$[/tex]

The price of a 9 minute phone call is $3. 15. What is the price of a 14 minute phone call
The price of a 14 minute phone call is $4.90.
We can use the given information to set up a proportion between the price and the duration of a phone call:
price of 9-minute call / 9 = $3.15 / 1
We can then solve for the price of a 1-minute call:
price of 1-minute call = ($3.15 / 1) / 9 = $0.35
Now that we know the price of a 1-minute call, we can use it to find the price of a 14-minute call:
price of 14-minute call = ($0.35 / 1) * 14 = $4.90
Therefore, the price of a 14 minute phone call is $4.90.

The heel of a show exerts a pressure of 198 pounds per square inch.
Convert this pressure into kilograms per square centimetre
use:
1 pound = 0.45 kilograms
1 square inch = 6.25 square centimetres
Step-by-step explanation:
1 pound = 0.45 kilograms
1 square inch = 6.25 square centimeters
First, let's convert the pressure from pounds per square inch to kilograms per square inch:
198 pounds/square inch × 0.45 kilograms/pound = 89.1 kilograms/square inch
Next, let's convert from kilograms per square inch to kilograms per square centimeter:
1 square inch = 6.25 square centimeters
89.1 kilograms/square inch ÷ 6.25 square centimeters/square inch = 14.256 kilograms/square centimeter
Therefore, the pressure of 198 pounds per square inch is equivalent to 14.256 kilograms per square centimeter.

Harry invests £8000 in a savings account. The account pays 2. 8% compound interest per year
work out the value of her investment after 4 years
give your answer to the nearest penny
the value of Harry's investment after 4 years is £8,999.21 to the nearest penny.
To work out the value of Harry's investment after 4 years, we can use the formula for compound interest:
[tex]A = P(1 + r/n)^(nt)[/tex]
where:
A is the final amount
P is the initial principal (the amount Harry invested)
r is the annual interest rate (as a decimal)
n is the number of times the interest is compounded per year
t is the time in years
In this case, P = £8000, r = 0.028 (2.8% expressed as a decimal), n = 1 (compounded annually), and t = 4. Plugging these values into the formula, we get:
A = £8000(1 + 0.028/1)
= £8000(1.028)
= £8,999.21
