I’m trying to figure out What equals 6 x 9?

Answer:

2 hours

Step-by-step explanation:

you can write two linear equations and then set them equal to each other to see when they intersect. so for the first equation which will be representing the junior space cadets distance from his house. this can be written as

d = 50t + 50

where t represents time and d represents distance. there is 50 being added to the equation since he had already been traveling for an hour

the second equation which will represent his sister Gwen can be represented as

d = 75t

Now we set them equal to each other

50t + 50 = 75t

50 = 25t

2 = t

Answer:

\(\underline{\boxed{\tt \angle x=75^{o}}}\)

Step-by-step explanation:

We know that all angles of a triangle always add up to 180°.

\(\angle BDH+\angle DBH+\angle DHB=180^o\)

\(39^o+36^o+\angle DHB=180^o\)

\(\angle DHB=105^o\)

Now, ∠DHB & ∠x are supplementary angles because they form a straight line.

\(\angle DHB+\angle x=180^o\)

\(105^o+\angle x=180^o\)

\(\angle x=75^o\)

Answer: 75°

Step-by-step explanation:

The the terms be x and y

The sum of the terms = x+y

Difference of terms = x-y

Product of the sun and differences will be expressed as:

(x-y)(x+y) = x²-xy+xy-y²

(x-y)(x+y) = x²-y²

Hence the product of the terms is equivalent to the difference of two squares of the terms

Answer: 345 + n

For finding the total, we have to add 345 with n.

Answer:

x = 104

y = 74

Step-by-step explanation:

According to the figure, the quadrilateral has two pairs of parallel, opposite sides. That makes the quadrilateral a parallelogram.

In a parallelogram, opposite sides are congruent and opposite angles are congruent.

Because of congruent sides:

x - 7 = 97

x = 104

Because of congruent angles:

y = 74

The recursive formula for Lindsey's scores is aₙ = aₙ₋₁ \(\times\) r, and the explicit formula is aₙ \(= 67 \times r^{(n-1).\)

To find the recursive and explicit formulas for the given geometric sequence, let's analyze the pattern of Lindsey's scores.

From the given information, we can observe that Lindsey's scores are increasing at the same rate.

This suggests that the scores form a geometric sequence, where each term is obtained by multiplying the previous term by a common ratio.

Let's denote the first term as a₁ = 67 and the common ratio as r.

Recursive Formula:

In a geometric sequence, the recursive formula is used to find each term based on the previous term. In this case, we can write the recursive formula as:

aₙ = aₙ₋₁ \(\times\) r

For Lindsey's scores, the recursive formula would be:

aₙ = aₙ₋₁ \(\times\) r

Explicit Formula:

The explicit formula is used to directly calculate any term of a geometric sequence without the need to calculate the previous terms.

The explicit formula for a geometric sequence is:

aₙ = a₁ \(\times r^{(n-1)\)

For Lindsey's scores, the explicit formula would be:

aₙ \(= 67 \times r^{(n-1)\)

In both formulas, 'aₙ' represents the nth term of the sequence, 'aₙ₋₁' represents the previous term, 'a₁' represents the first term, 'r' represents the common ratio, and 'n' represents the term number.

C can finish the work in 5 days, working alone.

Let C alone take x days to complete the work.

The following points should be kept in mind when approaching the solution of this problem :

Step 1: Find the work done by A alone in 1 day and that done by B alone in 1 day.

Step 2: Use the work done by A alone in 1 day and that done by B alone in 1 day to find the work done by all three A, B, and C together in 1 day.

Step 3: Use the work done by all three A, B, and C together in 1 day to find the number of days it takes for C to complete the job alone.

Now let's begin:

Step 1: Let A alone take 10 days to complete the job.

So, A alone can do the job in 1 day = 1/10.  

Let B alone take 20 days to complete the job.

So, B alone can do the job in 1 day = 1/20.

Step 2: Now we can find the work done by A, B, and C together in 1 day. We know that they finish the job in 4 days, so the total work done = 1/4.

The work done by A alone in 1 day = 1/10.

The work done by B alone in 1 day = 1/20.

Let C alone do the job in 1 day = 1/x.

Total work done in 1 day by A, B, and C = 1/10 + 1/20 + 1/x = 2/20 + 1/x = 1/4.

We can now simplify the equation: 1/x = 1/4 - 2/20 = 1/5.

x = 5

Therefore, C alone can do the work in 5 days, working alone.

The given equation is rearranged to obtain 9x - 1 - (41 - 5x) = 0. By simplifying and solving the equation, we get x = 3.

To solve this equation, we first simplify it by subtracting what is to the right of the equal sign from both sides of the equation. This gives us 9x - 1 - 41 + 5x = 0, which simplifies to 14x - 42 = 0. We then pull out the like factor of 14 to obtain 14(x - 3) = 0.

Next, we use the zero product property to find the values of x that make the equation true. We know that 14 can never equal 0, so we focus on the expression inside the parentheses. Setting x - 3 equal to 0, we get x = 3.

Therefore, the solution to the given equation is x = 3.

B. We are to describe the relationship between bridge length and breaking weight.

To do this, we need to check the graph.

In doing that, we will see that the breaking weight appears to decrease as the Bridge length increases.

We can conclude then that the breaking weight and bridge length have an inverse relationship.

That is shown in the graph.

The highest value of the breaking weight is 14 and that is when the value of bridge length is at its lowest (4).

The lowest value of the breaking weight is 3 and that is when the value of the bridge length is at its highest (11)

Hence, there is an inverse relationship between them.4)

The z-score corresponding to Ling's with a score of 74 on an exam with a mean of 80 and standard deviation of 8 is -0.75.

Given that Ling receives a score of 74 on an exam with a mean of 80 and a standard deviation of 8, we are to determine the z-score corresponding to her score.

The formula for z-score is given as follows:

z = (X - μ) / σ`

where X is the value of the variable (Ling's score in this case)

μ is the mean of the population

σ is the standard deviation of the population

Now,

Let X be the score Ling receives on the exam.

X = 74

Mean, μ = 80

Standard deviation, σ = 8

We can now use the formula for z-score and substitute the values into it:

z = (X - μ) / σ

z = (74 - 80) / 8

z = -6 / 8z = -0.75

Therefore, the z-score corresponding to Ling's score is -0.75.

a. The price of the consol is approximately $133.33.

b. The new price of the consol would be $100. The price of the consol falls by 24.99% and the interest rate rises by 1%.

c. Your holding period return is approximately -49.99%.

a. The price of the consol can be calculated using the formula for the present value of a perpetuity:

Price = Annual Payment / Interest Rate

In this case, the annual payment is $4 and the interest rate is 3%. Substituting these values into the formula:

Price = $4 / 0.03 ≈ $133.33

Therefore, the price of the consol is approximately $133.33.

b. To calculate the new price of the consol if the interest rate rises to 4%, we use the same formula:

New Price = Annual Payment / New Interest Rate

Substituting the values, we get:

New Price = $4 / 0.04 = $100

The percentage change in the price of the consol can be calculated using the formula:

Percentage Change = (New Price - Old Price) / Old Price * 100

Substituting the values, we have:

Percentage Change in Price = ($100 - $133.33) / $133.33 * 100 ≈ -24.99%

The percentage change in the interest rate is simply the difference between the old and new interest rates:

Percentage Change in Interest Rate = (4% - 3%) = 1%

Comparing the two percentages, we can see that the price of the consol falls by approximately 24.99%, while the interest rate rises by 1%.

c. The holding period return can be calculated using the formula:

Holding Period Return = (Ending Value - Initial Value) / Initial Value * 100

The initial value is the purchase price of the consol, which is $133.33, and the ending value is the price of the consol after one year with an interest rate of 6%. Using the formula for the present value of a perpetuity, we can calculate the ending value:

Ending Value = Annual Payment / Interest Rate = $4 / 0.06 = $66.67

Substituting the values into the holding period return formula:

Holding Period Return = ($66.67 - $133.33) / $133.33 * 100 ≈ -49.99%

Therefore, the holding period return is approximately -49.99%.
