If Tamara hiked a total of 340 minutes and her goal is to hike for at least 350 minutes every week, it means she fell short by 10 minutes.

Since it takes her the same amount of time to hike each mile, we can calculate the time it takes her to hike each mile.

On Thursday, she hiked a total of 1 + 3 + 4 = 8 miles. On Saturday and Sunday, she hiked a total of 5 + 4 = 9 miles. So in total, she hiked 8 + 9 = 17 miles.

To find the time it takes her to hike each mile, we divide the total time she hiked (340 minutes) by the total distance she covered (17 miles). Therefore, it takes her 340/17 = 20 minutes to hike each mile.

The best fit line for the data collected from 2007 to 2014 is represented by the equation Y = 0.15x + 8.27.

To determine the best fit line, we utilize linear regression analysis, which aims to find the line that minimizes the overall distance between the line and the data points. In this case, the equation of the best fit line is in the form Y = mx + b, where "m" represents the slope and "b" represents the y-intercept.

Given the equation Y = 0.15x + 8.27, we can interpret it as follows:

The slope (m) of 0.15 indicates that for every unit increase in the independent variable (x), the dependent variable (Y) increases by 0.15 units.

The y-intercept (b) of 8.27 indicates that when x is zero (2007 in this case), the expected value of Y is 8.27.

Therefore, the equation Y = 0.15x + 8.27 represents the best fit line for the data collected from 2007 to 2014, where Y represents the dependent variable (museum collections) and x represents the independent variable (years).

Since it is given that  ∠1 and ∠2 are supplementary angles, the value of x=26.

Given that ∠1 ​ and ∠2 are supplementary.

∠1=124°

∠2=(2x+4)°

We know that the sum of supplementary angles is 180°.

For, example if ∠A, ∠B ,∠C and ∠D are four angles of a quadrilateral, and ∠A and ∠D are supplementary. Then,

∠A + ∠D= 180°

To determine the value of q for which the lines qx - 7y + 10 = 20 and 4y + 3x + 9 = 0 are parallel to each other, we need to compare their slopes.

First, we'll rewrite the equations in the standard form y = mx + b, where m represents the slope of the line:

For the line qx - 7y + 10 = 20, rearranging the equation gives us:

qx - 7y = 10

-7y = -qx + 10

y = (q/7)x - 10/7

For the line 4y + 3x + 9 = 0, rearranging the equation gives us:

4y = -3x - 9

y = (-3/4)x - 9/4

From the equations, we can see that the slopes are q/7 for the first line and -3/4 for the second line.

For two lines to be parallel, their slopes must be equal. Therefore, we can equate the slopes and solve for q:

q/7 = -3/4

Cross-multiplying, we have:

4q = -21

Dividing both sides by 4, we find:

q = -21/4

Therefore, the value of q for which the lines are parallel to each other is -21/4.

Adam's credit card uses the adjusted balance method and has a 30-day billing cycle. Given his credit card activity over three months and an APR of 14.63%, we need to determine Adam's balance at the end of June.

To calculate Adam's balance at the end of June, we need to consider his credit card activity and apply the adjusted balance method. The adjusted balance method takes into account the beginning balance, transactions during the billing cycle, and payments made.

Let's calculate Adam's balance step by step:

1. April:

  - Beginning balance: $626.45

  - Purchases: $37.41 and $44.50

  - Ending balance: $626.45 + $37.41 + $44.50 = $708.36

2. May:

  - Payments: $65.50 and $104.77

  - Purchases: $24.89

  - Ending balance: $708.36 - $65.50 - $104.77 + $24.89 = $563.98

3. June:

  - Payments: $23.60

  - Purchases: $15.00 and $51.85

  - Ending balance: $563.98 - $23.60 + $15.00 + $51.85 = $607.23

To calculate the finance charges, we need to multiply the average daily balance by the daily periodic rate. The daily periodic rate can be calculated by dividing the APR by 365.

Average daily balance = (Beginning balance + Ending balance) / 2

                   = ($626.45 + $607.23) / 2

                   = $616.84

Daily periodic rate = 14.63% / 365 = 0.0004016

Finance charges = Average daily balance * Daily periodic rate * Billing cycle

               = $616.84 * 0.0004016 * 30

               = $7.41 (rounded to the nearest cent)

Finally, to find Adam's balance at the end of June, we add the finance charges to the ending balance:

Balance at the end of June = Ending balance + Finance charges

                         = $607.23 + $7.41

                         = $614.64

Therefore, Adam's balance at the end of June is approximately $614.64, which is not one of the options provided.

The property that allows one to set aside the order of operations is called the Commutative Property. The order of operations is also known as the PEMDAS rule.

The order of operations, also known as the PEMDAS rule (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction), is a fundamental principle in mathematics that dictates the sequence in which operations should be performed in an arithmetic expression. However, there are instances where the order of operations can be set aside or rearranged without affecting the final result. This is possible due to the Commutative Property, which applies to addition and multiplication.

The Commutative Property states that the order in which numbers are added or multiplied does not change the result. For addition, it means that the sum of two numbers remains the same regardless of the order in which they are added.

By applying the Commutative Property, one can rearrange the order of addition or multiplication operations, allowing for more flexibility in evaluating expressions. This property is particularly useful when simplifying or solving mathematical equations, as it enables us to change the order of terms without altering the final outcome. However, it's important to note that the Commutative Property does not apply to subtraction or division operations, and the order of operations should be followed strictly in such cases.

According to the question, the total weight is 240. Therefore,[tex]1P + 1D + 2N + 3Q = 240[/tex] [Equation 2]Let the value of a penny, nickel, dime, and quarter be 1C, 5C, 10C, and 25C respectively.According to the question, the total value is [tex]$12.30[/tex]. Therefore,[tex]1P + 5N + 10D + 25Q = 1230[/tex] [Equation 3]

From Equation 1,[tex]P = 120 - N - D - Q.[/tex]

we can substitute [tex]N = 3A and D = 3B[/tex] in the equation above.

This gives: [tex]4(3A) + 9(3B) + 24Q = 1110[/tex] Simplifying this,

we get:[tex]4A + 3B + 8Q = 370[/tex]

From here, we can substitute Q = 1, 2, 3, ... and check which values of A and B satisfy this equation. After some calculations, we find that Q = 7, A = 19, and B = 8.

The cost Type A coffee were used in the blend 40 pounds .

assume the number of pounds of Type A coffee used is 'x'.

Given:

Cost of Type A coffee = $5.95 per pound

Cost of Type B coffee = $4.65 per pound

Total cost of the blend = $796.0

The blend used three times as many pounds of Type B coffee as Type A.

set up the equation to represent the total cost:

Total cost = Cost of Type A coffee + Cost of Type B coffee

$796.0 = $5.95 × x + $4.65 × (3x)

Simplifying the equation:

$796.0 = $5.95x + $13.95x

Combining like terms:

$796.0 = $19.9x

Dividing both sides by $19.9:

x = $796.0 / $19.9

x ≈ 40

The wavelength at which the Hot Jupiter would be brightest can be estimated using Wien's displacement law, which states that the peak wavelength of radiation emitted by a black body is inversely proportional to its temperature.

According to Wien's displacement law, the wavelength (λ) is given by the formula λ = b/T, where b is the Wien's displacement constant and T is the temperature in Kelvin.

Using the given temperature of the Hot Jupiter (3118 K) and the Wien's displacement constant, which is approximately equal to 2.898 × 10^6 nm·K, we can calculate the peak wavelength as follows:

λ = (2.898 × 10^6 nm·K) / (3118 K) ≈ 928.51 nm

Therefore, the Hot Jupiter would be brightest at a wavelength of approximately 928.51 nanometers.
