The total number of pounds of flour he can buy is 7 pounds of flour

Let's assume that Mikal has $1 to spend on flour. According to the problem, he can buy:

- 12 pounds of wheat flour for $1, which means that the price of wheat flour is 1/12 = $0.0833 per pound.

- 6 pounds of rice flour for $1, which means that the price of rice flour is 1/6 = $0.1667 per pound.

- 4 pounds of almond flour for $1, which means that the price of almond flour is 1/4 = $0.25 per pound.

If Mikal spends $1 on an equal amount of all three types of flour, he will spend $1/3 = $0.3333 on each type of flour. To determine how many pounds of each type of flour he can buy, we need to divide $0.3333 by the respective price per pound of each type of flour:

- Wheat flour: $0.3333 / $0.0833 per pound = 3.9996 pounds (rounded to 4 pounds)

- Rice flour: $0.3333 / $0.1667 per pound = 1.9998 pounds (rounded to 2 pounds)

- Almond flour: $0.3333 / $0.25 per pound = 1.3332 pounds (rounded to 1 pound)

Therefore, Mikal can buy 4 pounds of wheat flour, 2 pounds of rice flour, and 1 pound of almond flour with $1. The total number of pounds of flour he can buy is:

4 + 2 + 1 = 7 pounds of flour.

Based on experimental probability, Abdul should expect 10 tails in the next 40 flips.

The experimental probability of getting tails is calculated as the ratio of the number of tails obtained in the experiment to the total number of coin flips.

In this case, the experimental probability of getting tails is 16/64, which simplifies to 1/4 or 0.25.

This means that in the long run, we would expect approximately 25% of coin flips to result in tails.

To determine how many of the next 40 flips Abdul should expect to come up tails based on experimental probability,

we can multiply the experimental probability by the total number of flips.

Abdul should expect 0.25 × 40 = 10 tails in the next 40 flips.

Experimental probability of getting tails = Number of tails obtained / Total number of coin flips

Experimental probability of getting tails = 16/64

Experimental probability of getting tails = 0.25 or 25%

Expected number of tails in the next 40 flips = Experimental probability of getting tails × Total number of flips

Expected number of tails in the next 40 flips = 0.25×40 = 10 tails

Step-by-step explanation:

The coordinates of point B: (0,6)

Coordinates of point C: (3,8)

A kite has 4 sides, of which we have 2 equal pairs, thus the coordinates of point D must be (6,6)

Answer:

(6,6)

Step-by-step explanation:

The question is asking us to complete the half figure, and make it a kite.  We can see that the 2 lines AB and BC are half of the shape.  In the attachment, I drew a line of symmetry down the middle of the shape.  

I also created a point, Y, down the red line, AC, to represent the perpendicular bisector of the 2 diagonals.  We can see that line segment BY is the radius of the entire line BD.  

This radius is 3 units, so we now know that the diameter horizontally is 6 units.  We can draw this on the other side to create point D.  

This means that point D is at (6,6).

Streets 2 and 3 are parallel and Street 1 is intersecting it

Parallel lines are two or more straight lines that continue indefinitely without ever crossing each other, despite their extended lengths. They have an equal inclination and remain the same distance apart at all times. Consequently, intersections will never occur between them.  

On the contrary, if non-parallel lines exist, they intersect to create one point, famously known as the 'point of intersection'. This specific point supplies the solution to the system of equations formed by the two lines.

Answer: 9 x 10^4

Step-by-step explanation:

9 ten thousands in standard form is written like this: 90,000

To convert this into scientific notation, we simply count how many spaces we want to move the decimal point.

So far, our number looks like this with a decimal point: 90000.0

To make this number equal to 9, we have to move the decimal point 4 spaces to the left.

The 4 then becomes our exponent.

So now we have 9 by itself, and all we do is multiply it by 10 with an exponent of 4, to show you are multiplying 10 four times.

Therefore, 9 ten thousands written in scientific notation is 9 x 10^4

"The probability that the first freshman to arrive will be seated at a round table is (5/13)."

To calculate the probability, we need to determine the total number of seats and the number of seats at round tables.

There are 8 rectangular tables with 6 chairs each, so the total number of seats at rectangular tables is 8 * 6 = 48.

There are 5 round tables with 4 chairs each, so the total number of seats at round tables is 5 * 4 = 20.

The total number of seats in the community center is 48 + 20 = 68.

The probability of the first freshman being seated at a round table is the number of seats at round tables (20) divided by the total number of seats (68), which gives us 20/68 = 5/17.

Therefore, the correct answer is option C: 5/17.

To save $220 per month while working a job that pays $8.50 per hour with deductions of 26.15%, you would need to work approximately 43 hours per month, rounded up to the nearest whole hour.

To calculate how many hours you would need to work, you need to first determine your hourly pay after deductions. To do this, subtract the percentage of deductions (26.15%) from 100% (100% - 26.15% = 73.85%). Then, multiply your hourly rate by this percentage to get your effective hourly rate after deductions: $8.50 x 0.7385 = $6.27.

To save $220 per month, you need to earn at least $220 more than your expenses from your second job. Assuming a 4-week month, your expenses would need to be at most $55 per week ($220/4 weeks = $55/week).

To earn $55 per week, you need to work for $55/$6.27 = 8.77 hours per week. Rounded up to the nearest whole hour, you would need to work approximately 9 hours per week.

Multiplying this by 4 weeks gives you a total of 36 hours. However, since you need to earn slightly more than $55 per week to account for taxes and rounding, you would need to work approximately 43 hours per month.

Given the area (A) is 7,701 square centimeters, the longer base (b1) measures 119 centimeters, and the shorter base (b2) is 85 centimeters, we can solve for the height (h) using the following steps:

1. Plug in the given values into the formula: 7,701 = (1/2)(119 + 85)h
2. Simplify the expression inside the parentheses: 7,701 = (1/2)(204)h
3. Multiply the two numbers inside the parentheses: 7,701 = 102h
4. Divide both sides of the equation by 102 to solve for h: h = 7,701 / 102

The equilibrium level of output in the economy can be calculated using the following formula:

Y = C + I + G + NX

Where:

Y = Equilibrium level of output

C = Consumption

I = Investment

G = Government spending

NX = Net exports

We can calculate consumption using the marginal propensity to consume (MPC) and autonomous spending (A):

C = MPC(Y - T) + A

Where:

T = Taxes (assumed to be 0 in this case)

Substituting in the given values:

C = 0.8(Y - 0) + 2000

C = 0.8Y + 2000

Substituting in the given values for investment, government spending, and net exports:

Y = 0.8Y + 2000 + 7500 + 10000 - 1000

Y = 0.8Y + 19500

Solving for Y:

0.2Y = 19500

Y = 97500

Therefore, the equilibrium level of output in the economy is $97,500.

If net exports increase by $1000, then the new value of net exports (NX) is 0.

Substituting the new value of NX into the formula:

Y = 0.8Y + 2000 + 7500 + 10000 - 0

Y = 0.8Y + 19500

Solving for Y:

0.2Y = 19500

Y = 97500

Therefore, the equilibrium level of output in the economy is still $97,500.

The multiplier is calculated as:

Multiplier = 1 / (1 - MPC)

Substituting in the value of MPC:

Multiplier = 1 / (1 - 0.8)

Multiplier = 5

Therefore, the multiplier in this case is 5.

Let's assume that the length of the rectangle is x and the width is y.

The perimeter of the rectangle is given by:

P = 2x + 2y

Substituting P = 62, we get:

62 = 2x + 2y

Simplifying the above equation, we get:

x + y = 31

The area of the rectangle is given by:

A = xy

To find the area, we need to solve for one of the variables, either x or y. We can use the equation x + y = 31 to solve for y in terms of x:

y = 31 - x

Substituting this expression for y in the equation for the area, we get:

A = x(31 - x)

Expanding the above expression, we get:

A = 31x - x^2

To find the maximum area, we need to find the value of x that maximizes A. We can do this by completing the square:

A = - (x^2 - 31x)

A = - [(x - 15.5)^2 - 240.25]

A = 240.25 - (x - 15.5)^2

The maximum area occurs when x = 15.5, so the dimensions of the rectangle are:

x = 15.5 mm

y = 31 - x = 15.5 mm

The area of the rectangle is:

A = xy = 15.5 mm × 15.5 mm = 240.25 mm^2

p + q + 36 = 0 is the equation that is true. From this equation, we can say that p + q = -36.

If we substitute x = 1 in the given function, we get:

f(1) = [tex](1)^4 + 5(1)^3 + p(1)^2 + q(1) + 30[/tex]

= 1 + 5 + p + q + 30

= p + q + 36

We are given that f(1) = 0. Therefore, we have:

p + q + 36 = 0

This is the equation that is true. From this equation, we can say that p + q = -36.

Now, let's see why this is the case. When we substitute x = 1 in the given function and get f(1) = 0, it means that (1, 0) is a point on the graph of the function. This point lies on the x-axis, which means that the function intersects the x-axis at x = 1. Since the x-axis is the line y = 0, this means that f(x) = 0 when x = 1.

Using this information, we can write an equation in terms of p and q. If we substitute x = 1 in the given function and get f(1) = 0, it means that:

f(x) = [tex](x - 1)(x^3 + 6x^2 + (6+p)x + (30-q))[/tex]

Therefore, we have:

[tex](x - 1)(x^3 + 6x^2 + (6+p)x + (30-q)) = 0[/tex]

Since (1,0) is a point on the graph of the function, we know that x = 1 is a root of this equation. Therefore, we have:

[tex](x - 1)(x^3 + 6x^2 + (6+p)x + (30-q)) = (x - 1)(x^2 + (7+p)x + (36-p-q))[/tex]

We know that (x - 1) is a factor of this equation, so we can use polynomial long division to divide the expression [tex](x^2 + (7+p)x + (36-p-q))[/tex] by (x - 1). The quotient will give us the other two roots of the equation. However, we do not need to find these roots to answer the question. All we need to know is that p + q = -36.

Let's denote the cost of one apple as 'a' and the cost of one banana as 'b'. We can set up a system of two equations to represent the given information:

4a + 9b = 12.70   (equation 1)

8a + b = 17.70    (equation 2)

We can use either substitution or elimination method to solve for 'a' or 'b'. Let's use the elimination method by multiplying equation 2 by 9 and subtracting it from equation 1:

4a + 9b = 12.70

-(72a + 9b = 159.30)   (multiplying equation 2 by 9)

------------------

-68a = -146.60

Dividing both sides by -68, we get:

a ≈ 2.16

Therefore, the cost of one apple is approximately $2.16.

50% of the beads Nolan received were orange.

To find the percentage of beads that were orange, we need to divide the number of orange beads by the total number of beads and then multiply by 100.

Percentage of orange beads = (Number of orange beads / Total number of beads) * 100

In this case, Nolan received a total of 86 beads, and 43 of them were orange.

Percentage of orange beads = (43 / 86) * 100

Calculating this expression:

Percentage of orange beads = 0.5 * 100

Percentage of orange beads = 50%

Therefore, Out of total number of  beads Nolan received, 50% were orange.
