Answer:

First you do what is in the parentheses.

2+4= 6

The equation is now:

6(6) -1 / 2 *3 + 1 =

Then you do the division:

-1 / 2 = -0.5

6(6) (-0.5) * 3 + 1 =

3 + 1 = 4

-0.5 * 4 = -2

The equation is now:

6 * 6 * -2

6 * 6 = 36

36 * -2 = -72

Answer:

5 markers :)

Step-by-step explanation:

Let's say that

x = the number of pens

y = the number of pencils

Anthony spent $2.80 to buy a total of 12 pens and pencils

0.35x + 0.15y = 2.80

x + y = 12

by solving the system of equations

0.35x + 0.15y = 2.80

x + y = 12

we find

x = 5 pens

y = 7 pencils

Answer:

Anthony bought 7 markers.

Step-by-step explanation:

Hi, so in this problem we will need 2 equations! One to represent the unknown numbers of pens and markers, and the other to represent the prices of the pens and markers.

Our first equation should look like:

12 = p + m

12 represents the total number of items purchased, p is the letter for pens, and m is the letter for markers, as the number of each is unknown.

Next, the other equation shoud look like this:

2.80 = 0.35 p + 0.15 m

This is because the total price is 2.80 and the pens cost 35 cents each, and each  marker costs 15 cents.

Now, we need to plug one of the equations into the other to figure out the variable for the marker. Let's change the 12 = p +m equation, so that the variable p is isolated.

The equation should now look like this: P = 12 - m.

Now, let's plug this equation into the p variable for the 2.80 = 0.35p + 0.15m.

It should look like this: 2.80 = 0.35(12 - m) + 0.15 m

Now, let's distribute! :)

The equation should now be distributed as such:

2.80 = 4.2 - 0.35 m + 0.15 m.

Now, let's simplify the equation!

-1.4 = -0.2 m

Now, all that's left is to divide the -1.4 by the -0.2.

You should get 7, which is the total number of markers Anthony bought!

Hope this helps!

To find a plane containing the point (-5, 6, -6) and the line defined by parametric equations x(t) = 7 - 5t, y(t) = 3 - 6t, and z(t) = -6 - 6t, we can use the point-normal form of the equation of a plane.

The equation of a plane in point-normal form is given by Ax + By + Cz + D = 0, where (A, B, C) is the normal vector to the plane, and (x, y, z) are the coordinates of a point on the plane. We can determine the normal vector by taking the cross product of two direction vectors in the plane.

The direction vector of the line can be obtained by taking the coefficients of t in the parametric equations, which gives us (-5, -6, -6). We can choose any two non-parallel direction vectors in the plane, for example, (1, 0, 0) and (0, 1, 0). Taking the cross product of these two vectors, we get the normal vector (0, 0, -1).

Now, we can substitute the values of the point (-5, 6, -6) and the normal vector (0, 0, -1) into the point-normal form equation. This gives us 0*(-5) + 0*6 + (-1)*(-6) + D = 0, which simplifies to D = -6. Thus, the equation of the plane containing the point (-5, 6, -6) and the given line is 0*x + 0*y - z - 6 = 0, or simply -z - 6 = 0.

To fairly represent the situation of Celine's field hockey team making it to the finals, we can use simulations like a dice roll or a computer program to simulate the tournament multiple times and determine the likelihood of Celine's team winning at least 3 games and making it to the finals.

Celine's field hockey team has a 50% chance of winning each game in the Swift County Tournament. They need to win at least 3 out of 4 games to make it to the finals on Sunday. We need to determine how likely it is that they will make it to the finals.

To simulate this situation, we could use a random number generator or dice. Each time we roll the dice if the number is 1-3, it represents a win for Celine's team, and if it is 4-6, it represents a loss. We would then repeat this simulation 100 times or more to get a good idea of the likelihood of Celine's team making it to the finals.

Another simulation that could be used is a computer program that simulates a tournament. We could program the computer to randomly generate a winner for each game based on the 50% chance of winning, and then repeat the tournament multiple times to determine how often Celine's team makes it to the finals.

In both simulations, we would calculate the number of times Celine's team wins at least 3 games and makes it to the finals. We would then divide this number by the total number of simulations to determine the likelihood of Celine's team making it to the finals.

Answer:

Step-by-step explanation:

To solve this problem, we can use the formula for calculating simple interest:

I = P * r * t

where:

I = interest earned

P = principal (initial amount of money)

r = rate of interest

t = time (in years)

We can rearrange the formula to solve for the principal:

P = I / (r * t)

In this case, we know that Gill earned $2306 in interest after one year at a rate of 6%. So:

I = $2306

r = 0.06

t = 1 year

Substituting these values into the formula, we get:

P = $2306 / (0.06 * 1)

P = $38,433.33

Therefore, the initial amount of money that Gill deposited into her account was $38,433.33.

Answer: 20 over 4     or      4/20

Step-by-step explanation:             I belive this is you answer for number 2.

a) The Mach number at the duct entrance is 0.878.

b) The temperature and pressure in the square section is 727 R.

c) The maximum length of the duct that can be added before the flow chokes is 40.9 feet.

a) To determine the Mach number at the duct entrance, first use the isentropic flow equation to calculate the velocity.

\($\frac{2}{\gamma-1}\left[\left(\frac{P_{0}}{P_{1}}\right)^{\frac{\gamma-1}{\gamma}}-1\right]=M^{2}$\)

Where P0 is the ambient pressure, P1 is the static pressure, and M is the Mach number. Assuming a perfect gas with γ = 1.4,

\($\frac{2}{1.4 - 1}\left[\left(\frac{14.7}{P_{1}}\right) ^{\frac{1.4-1}{1.4}} - 1\right] = M^{2}$\)

Because all we are given is the ambient pressure and a Mach number of 0.50 in the second section, the Mach number at the entrance can be found by solving this equation for M:

\($M = \sqrt{\frac{2}{1.4 - 1}\left[\left(\frac{14.7}{P_{1}}\right) ^{\frac{1.4-1}{1.4}} - 1\right] } = 0.878$\)

b) To determine the temperature and pressure in the 8 x 8 in. square section, use the isentropic flow equation for area ratio

\($\frac{A_{1}}{A_{2}} = \Big(\frac{2}{\gamma+1}\Big)^{\frac{\gamma + 1}{2(\gamma -1)}}M^{\frac{2}{\gamma - 1}}$\)

The area ratio for this problem is:

\($\frac{12^{2}} {8 \times 8} = 4$\)

With a Mach number of 0.50 and γ = 1.4, the equation becomes

\($4 = \Big(\frac{2}{\gamma+1}\Big) ^{\frac{\gamma+1}{2(\gamma-1)}} \big(0.5 \big) ^{\frac{2}{\gamma-1}}$\)

Solving this equation yields

\($P_{2} = 3.27 \quad psia$\)

\($T_{2} = 727 \quad \text{R}$\)

c) To determine the amount of 8 × 8 in. duct that can be added before the flow chokes, use the same equation used in part b. with M=1. The area ratio for this problem is again 4, so the equation becomes

\($4 = \Big(\frac{2}{\gamma+1}\Big) ^{\frac{\gamma+1}{2(\gamma-1)}} \big(1 \big) ^{\frac{2}{\gamma-1}}$\)

Solving for P₂ yields

\($P_{2} = 1.90 \quad psia$\)

Assuming f = 0.04 in the 8 × 8 in. duct, the maximum length of this duct that can be added before the flow chokes is

\($L_{max} = \frac{2 \times 0.04 \times 14.7}{1.90 - 0.04 \times 14.7} \times \frac{144}{\pi D_{2}^{2}} = 40.9 \quad ft$\)

Therefore,

a) The Mach number at the duct entrance is 0.878.

b) The temperature and pressure in the square section is 727 R.

c) The maximum length of the duct that can be added before the flow chokes is 40.9 feet.

To achieve the goal of obtaining an estimate of the annual health insurance deductible acceptable to its employees, the company can consider using a stratified sampling plan.

In a stratified sampling plan, the population is divided into homogeneous groups called strata based on relevant characteristics. In this case, the company can stratify the employees based on their respective states or regions. Since employee insurance plans vary greatly from state to state, this stratification will help ensure that each state or region is properly represented in the sample.

Once the employees are stratified, the company can then randomly select a proportional sample from each stratum. This means that the sample size from each stratum is proportional to the size of that stratum in the overall population. This approach will provide a representative sample that captures the diversity of insurance plans across different states or regions.

By implementing a stratified sampling plan, the company can obtain reliable estimates of the annual health insurance deductible acceptable to its employees while accounting for the variation in insurance plans across different states or regions.
