The equation for the Bowler world is c = $1.1g + $5,

The equation for the Lucky spares is c = $1.5g + $3.

and the cost is the same for 5 games and the cost is $10.5.

Each term in a linear equation has an exponent of 1, and when this algebraic equation is graphed, it always produces a straight line. It is called a "linear equation" for this reason.

Both linear equations with one variable and those with two variables exist.

Given the Bowler, World charges $5.00 to rent shoes and $1.10 per game. Lucky Spares charges $3.00 for shoes and $1.50 per game.

Part A

using g for the number of games and c for the cost

for Bowler World

charges for shoes = $5

cost for per game = $1.1

cost for g games = $1.1g

total cost c =  $1.1g + $5 ..........(1)

for Lucky spares

charges for shoes = $3

cost for per game = $1.5

cost for g games = $1.5g

total cost c =  $1.5g + $3 ..........(2)

B. if the cost used in both places is equal then equation 1 equals equation 2

so $1.1g + $5 = $1.5g + $3

1.5g - 1.1g = 5 - 3

0.4g = 2

g = 2/0.4

g = 5

and cost is c =  $1.1g + $5

c = 1.1*5  + 5

c = 5.5 + 5

c = $10.5

Hence equations are  c =  $1.1g + $5 and  c =  $1.5g + $3,

and the cost is same for 5 games and the cost is $10.5.

Tthe population of the colony after 2 hours is 64a

From the question, we have the following parameters that can be used in our computation:

Rate = doubles every 20 minutes

Represent the initial population with a

So, we have the following representation

f(t) = a(2)^t

Where t is the number of 20 minutes in the time

The time is given as 2 hours

So, we have

t = 2 hours/20 minutes

Evaluate

t = 6

The function becomes

f(t) = a(2)^6

Evaluate

f(t) = 64a

hence, the population is 64a

The value of 'x' in the expression (1/2)(4x - 5) + 5/2 = 10 is, x = 5.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, An expression  (1/2)(4x - 5) + 5/2 = 10.

(1/2)(4x - 5) = 10 - 5/2.

(1/2)(4x - 5) = (20 - 5)/2.

(1/2)(4x - 5) = 15/2. ('2' on both sides of the denominator cancels)

4x - 5 = 15.

4x = 20.

x = 5.

The two numbers are 7/6 and 5 when the sum of two numbers is 3 more than four times the first number.

Let's call the two numbers x and y, where x is the first number and y is the second number.

The problem gives us two equations that relate the two numbers:

[tex]x + y = 3 + 4x\\y - x = 2y - 10[/tex]

We can substitute the expression for y from equation 1 into equation 2:

[tex]y - x = 2(3 + 4x) - 10[/tex]

Expanding the right side and simplifying, we get:

[tex]y - x = 6 + 8x - 10\\y - x = 8x - 4[/tex]

Adding x to both sides:

[tex]y = 9x - 4[/tex]

Substituting this expression for y into equation 1:

[tex]x + (9x - 4) = 3 + 4x[/tex]

Expanding and simplifying the right side:

[tex]10x - 4 = 3 + 4x[/tex]

Subtracting 4x from both sides:

[tex]6x - 4 = 3[/tex]

Adding 4 to both sides:

[tex]6x = 7[/tex]

Dividing both sides by 6:

[tex]x = 7/6[/tex]

Substituting this value of x back into the expression for y:

[tex]y = 9x - 4 = 9 * (7/6) - 4 = 63/6 - 4 = 9 - 4 = 5[/tex]

So the two numbers are 7/6 and 5.

Answer:

[tex]\frac{1}{9}[/tex] or 11.11%

Step-by-step explanation:

P(A) = probability of an event

f = favored outcomes

N = number of total outcomes

[tex]P(A)=\frac{f}{N}[/tex]

In this equation there is one favored income, when the first counter is blue and the second one is green. There are also nine total outcomes. This means that the equation necessary is:

[tex]P(A)=\frac{1}{9}[/tex]

The probability that Mike takes a blue counter and then Ellie takes a green counter is [tex]\frac{1}{9}[/tex] or around 11.11%

The equation solved for the variable y is:

y = 4 - x

To do this, we need to isolate the variable y in the given equation.

We have the equation:

3y -2 = 10 - 3x

Adding 2 in both sides we will get:

3y -2 +2 = 10 - 3x + 2

3y = 12 - 3x

Now we can divide both sides by 3 to get:

3y/3 = (12 - 3x)/3

y = 4 - x

That is the equation solved for y.

The length of the stone walkway would be 536.64 inches.

To find the length of the stone walkway, the landscaper needs to determine the length of the diagonal of the rectangular lawn.

The length of the diagonal can be calculated using the Pythagorean theorem:

[tex]d^2 = l^2 + w^2[/tex]

Where d is the length of the diagonal, l is the length of the rectangle, and w is the width of the rectangle.

So to find the length of the walkway, the landscaper would need to know the length and width of the rectangular lawn.

Suppose a landscaper wants to place a stone walkway from one corner of a rectangular lawn that is 40 feet long and 20 feet wide to the opposite corner.

Using the Pythagorean theorem, we can calculate the length of the diagonal:

[tex]d^2 = 40^2 + 20^2[/tex]

[tex]d^2 = 1600 + 400[/tex]

[tex]d^2 = 2000[/tex]

[tex]d =\sqrt{2000}[/tex]

[tex]d = 44.72 feet[/tex]

Rounding to the nearest inch, the length of the stone walkway would be 44.72 * 12 = 536.64 inches, which can be rounded to 536 inches.

Above 700: 5%, Above 550: 34%, Between 400 and 550: 26%, Below 400: 16%, Below 550: 55%.

To calculate the fraction of students who scored above 700, we can use the z-score formula, which is (x - μ) / σ, where x is the score, μ is the mean, and σ is the standard deviation. In this case, μ = 500 and σ = 100. Plugging in 700 for x, we get (700 - 500) / 100 = 2. This corresponds to a z-score of 2, which is .9772, meaning that 97.72% of the scores are below 700. This means that 5% are above 700. To calculate the fraction of students who scored above 550, we can use the same formula, but with 550 for x. This gives us (550 - 500) / 100 = .5, which corresponds to a z-score of .5, meaning that 84% of the scores are below 550. This means that 34% are above 550. To calculate the fraction of students who scored between 400 and 550, we can subtract the z-score of 400 from that of 550. This gives us .84 - .2 = .64, meaning that 64% of the scores are below 550. This means that 26% are between 400 and 550.

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
