The expression  that could represent the cost of 7 t-shirts and a $6 tax is (a)  7n + 6

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

Number of shirts = 7

Tax = $6

Represent the cost of each shirt with n

So, we have the following equation

Total cost = Number of shirts * Cost of each shirt + Tax

Substitute the known values in the above equation, so, we have the following representation

Total cost = 7 * n + 6

Evaluate

5.8525 grams out of 25 grams of xenon will be left after 11 days.

The amount of time needed for an isotope's radioactivity to decrease to 50% of its initial value.

The given data is

T1/2=5.25 days.

No=25g

T=11 days

We'll have to find the disintegration constant first.

The formula for finding it is

T½ = In2 / λ

T½ = half-life

λ = disintegration constant

λ = In2 / T½

λ = 0.693 / 5.25

λ = 0.132

In(N / No) = -λt

where,

N = final mass of the radioactive sample

No = initial mass of the sample

λ = disintegration constant

t = time for the radioactive decay

In(N/No) = -λt

N / No = e^-λt

N = No(e^-λt)

N = 25 × e^-(0.132 × 11)

N=5.8525 g.

Convert the given to slope-intercept form, y = mx + b, to make it equivalent:

Answer:

the portion of the x-axis that the straight line cuts is the interval [5r, -5r].

Step-by-step explanation:

To find the portion of the x-axis that the straight line cuts, we first need to solve the equation for θ. The sine function has a range of [-1, 1], so the value of r must be greater than or equal to 5 in order for the equation to have a solution.

To solve the equation, we can use the fact that sin(π/4 - θ) = cos(θ). Therefore, the equation can be rewritten as:

cos(θ) = 5

We can then use the fact that cos(θ) = x/r to solve for x:

x = 5r

Therefore, the portion of the x-axis that the straight line cuts is the interval [5r, -5r].

Note that this is only valid if r is greater than or equal to 5. If r is less than 5, there are no solutions to the equation and the straight line does not cut the x-axis.

Answer:

AngleCAB = 44°

AngleHAB = 66°

Step-by-step explanation:

AngleEAF is a right angle, equal to 90°.

EH and DC are just two intersecting lines. They form a couple of pairs of vertical angles. Vertical angles are equal to each other. We'll use the vertical angles, AngleEAD and CAH.

Angle EAD and CAH are equal to each other.

EAD = CAH

90°+20° = 2x + 3x

Combine like terms.

110° = 5x

Divide by 5

110/5 = x

22 = x

Angle CAB

= 2x

= 2(22)

= 44

AngleCAB = 44°

AngleHAB

= 3x

= 3(22)

= 66

AngleHAB = 66°

At 9 AM Bob could declare the pool was full of water, using given information about fill rate, discharge rate and time.

What is fill rate and discharge rate ?

The definition of fill rate is the percentage of customers orders you are able to meet without running out of stock at any given time.

The discharge rate is the amount of fluid that is passing through a given cross sectional area per unit time.

We need to divide it in 3 parts:

Part 1: When only 1 hose is filling the pool at 3 gal per hr.

Part 2 : When after 10 hours animals started drinking water .

Part 3: When 2nd hose also started at the rate 2 gal per hr.

Part 1:

For 10 hours it get started . So, pool get filled is 30gal.

Part 2:

After 10 hours, rate decreased by animals at 1 gal/hour.

So, rate = 3-1 = 2 gal/hour.

So, water filled for 5 hour = 10 gal.

So, total pool is filled = 10 + 30 = 40 gal.

Remaining = 60 - 40 = 20 gal.

Part 3:

2nd hose is added at the rate 2gal/hour.

Now, rate = 2+2 = 4 gal/hour.

Time taken for 20 gal = 5 hours.

So, total time taken = 10 + 5 +5

                                 = 20 hours.

We need to find the time ,

Time at which water is started = 1pm

1PM + 11hours = 12AM

For remaining , 9 hours

12AM + 9hours = 9AM.

Given,

Here we have the three long wires hang vertically. The distance between wire 1 and wire 2 is 23.0 cm On the left, wire 1 carries an upward current of 1.50 A. To the right, wire 2 carries a downward current of 3.60 A. Wire 3 is to be located such that when it carries a certain current, each wire experiences no net force.

And now we need to find the position of wire 3 and the magnitude and direction of the current in wire 3.

As per the given question, we know that the

=> Current in wire 1, i1 =1.2A upward

=> Current in wire 2, i2=5A downward

And the distance between wire 1 and 2 is calculated is

=> 20cm = 0.2m

Here the current is calculated as

=> F/l = μo•i1•i3/2πx

So,

=> F/l=6×10⁻⁶N/m

=> 6×10⁻⁶ = μo•i1•i3/2πx

=> 6×10⁻⁶ =4π×10⁻⁷×1.2×i3/(2π×0.0632)

When we do Cross multiply,

=> 6×10⁻⁶×2π0.0632=4π×10⁻⁷×1.2×i3

=> 2.383×10⁻⁶=4π×10⁻⁷×1.2×i3

=> i3= (2.383×10⁻⁶)/(4π×10⁻⁷×1.2)

Therefore, i3= 1.58A and it's direction is downward.

Given,

Suppose that there are 5 children in a gymnastics class.

One day, they count the number of steps each person takes while walking on their hands until they lose balance and come down.

The mean number of steps these children took while walking on their hands is 20 steps.

Here we need to find the the population and parameter.

Based on the given question,

We know that the parameters are descriptive measures of an entire population and their values are usually unknown because it is infeasible to measure an entire population.

Therefore, you can take a random sample from the population to obtain parameter estimates.

Similarly, for the population could simply be referred to as the total number or set of similar objects or subjects related to a certain study or research.

Here the given scenario described above, the area of interest is a particular gymnastic class, therefore all individuals or children belonging to this particular gymnastic class makes up the population.

And then the parameter on the other hand are statistical metrics, values or calculations derived from the population figure or information.

So, the mean value of steps obtained from the step counts of the population data is called the parameter.

And the parameter is a value that describes a characteristic of an entire population, such as the population mean.

Therefore, the population mean and standard deviation are two common parameters.

If the probability that the bug moves to its starting vertex on its tenth move is m/n , then the value of m+n is 683 .

In the question ,

it is given that ,

the bug starts from a vertex of an equilateral triangle , and

in each move , it randomly selects one of  two vertices where it is not currently located .

Let the probability that the bug is at its starting vertex after n moves is Pₙ .

If the bug is on its starting vertex after n moves, then it must be not on its starting vertex after n-1 moves .

At this point it will has (1/2) chance of reaching starting vertex in the next move.

Thus Pₙ =  (1/2)(1 - Pₙ₋₁) . P₀ =1 ,

So , the probabilities in each move can be written as

P₁ = 0 ,  P₂ = 1/2, P₃ = 1/4 , P₄ = 3/8 , P₅ = 5/16, P₆ = 11/32 , P₇ = 21/64 , P₈ = 43/128, P₉ = 85/256, P₁₀ = 171/512 ,

So , the tenth move P₁₀ is given as 171/512 , which is m/n .

So, m + n is = 171 + 512 = 683 .

Therefore , the value of m+n is = 683 .
