Solution:

A triangle is a polygon with three sides and three angles. Types of triangles are scalene, acute, obtuse, isosceles, equilateral and right angled triangle.

A right angled triangle is a triangle with one angle equal to 90 degrees. The longest side of a right angled triangle is known as the hypotenuse. Trigonometric identities is used to show the relationship between the angles and sides of a right angled triangle, i.e.:

sinθ = opposite/hypotenuse; cosθ = adjacent / hypotenuse; tanθ = opposite / adjacent

From the image:

let the distance from jack to the base of the building be x, hence:

tan60 = x / 60

x = 60 * tan60 = 104 ft.

Answer:

q = 55

Step-by-step explanation:

      \(p\ \alpha\ \frac{1}q} \\\\p = k \times \frac{1}{q}\\\\22 = k \times \frac{1}{5}\\\\22 \times 5 = k\\\\k = 110\\\\\)

Find q when p = 2

   \(p = k \times \frac{1}{q}\\\\2 = 110 \times \frac{1}{q}\\\\2 \times q = 110\\\\q = \frac{110}{2}\\\\q = 55\)

Answer:

\(y=-\frac{2}{5}x+1\)

Step-by-step explanation:

Write in slope-intercept form,  y = m x + b .

to convert 25min into hours we divide 25 by 60 so the answer would be 0.416 hours

the formula to find the distance is we multiply speed and time so

distance=4km/p X 0.416 hours =1.664

so now we have the first answer

now we do the same thing for the other part of the question

distance= timeXspeed

distance=0.416X3=1.248

then we add to find total distance

1.248+1.644=2.912

2.912 is the total distance

Answer:

No they are not similar

Step-by-step explanation:

To make them similar, they would have to have the same angle measurements. The first triangle has 81, and 60 if you add them then subtract the sum by 180 you get the last angle measure, which is 39. 39 is not the same as 40 in the second triangle, proving they do not have the same angles and are not similar

Answer:

14%

Step-by-step explanation:

Using the formula for calculating Simple interest.

Simple interest = Principal × Rate × Time/100

Given Simple interest = $16.68

Principal = loan obtained = $580

Time (in years) = (75/365) year {we will convert days to year}

Rate (in %) = ?

On substituting to get the rate

16.68 = {580×R×(75/365})/100

16.68 = 580×R×75/365×100

16.68×36,500 = 580×R×75

608,820 = 43,500R

R = 608,820/43,500

R = 13.99℅

Rate ≈ 14%

The interest rate that was charged for the loan is approximately 14%

The mean absolute percentage error is 33.3%

The mean absolute percentage error measures the forecast accuracy by determining how well a particular forecasting method is able to reproduce the time series data that are already available.

This method is referred to as the forecasts of accuracy, which help to measure the number of errors that are in a former forecast.

Then this would factor these errors into a new forecast while making adjustments to the new forecast.

Forecasted sales were $4,000

Actual sales were $3,000

Absolute error = |Actual sales - Forecasted sales|

                        = |3,000-4,000|

                        = 1000

Mean Absolute error percentage = (Absolute error / Actual sales) *100%

                                                       =(1000/3000)*100

                                                       = 33.33%

Hence, The Mean Absolute error percentage is 33.3%

Step-by-step explanation:

a general line equation is

y = ax + b

the original line is

y = 3/5 x + 10

the factor of x is always the slope (inclination of the line).

it is "y change/x change".

the slope of a perpendicular line (angle of 90°) is turning the slope of the original line upside-down and flips the sign.

so, it is -5/3.

we use the point information to get the right "b" for our new line :

-5 = -5/3 × 15 + b

-5 = -5×5 + b

-5 = -25 + b

b = 20

so, the perpendicular line equation going through (15, -5) is

y = -5/3 x + 20

After your grandmother makes a $5,000 deposit on your 18th birthday, the amount in the savings account can be calculated using compound interest. Assuming the account pays an interest rate of 7%, the amount in the account immediately after the deposit can be determined by applying the compound interest formula.

To calculate the amount in the savings account after the deposit on your 18th birthday, we can use the compound interest formula: A = P(1 + r/n)^(nt), where A represents the final amount, P is the principal (initial deposit), r is the interest rate, n is the number of times interest is compounded per year, and t is the number of years.

In this case, the initial deposit is $5,000, the interest rate is 7% (or 0.07 as a decimal), and the deposit is made on your 18th birthday, which means the time is 17 years. Since no information is given about the compounding frequency, let's assume it is compounded annually (n = 1).

Plugging in the values into the compound interest formula, we have A = 5000(1 + 0.07/1)^(1*17) = 5000(1.07)^17 ≈ $15,128.

Therefore, the amount in the savings account immediately after your grandmother makes the deposit on your 18th birthday is approximately $15,128, rounded to the nearest dollar.

Answer:

1. -11

Step-by-step explanation:

2. All real numbers

3)  since we don't have the information about the interest paid (I), we cannot determine the rate of interest at this time.

(1) To find the total amount Adrian paid in 36 months, we can multiply the monthly installment by the number of installments:

Total payment A = Monthly installment * Number of installments

              = $375 * 36

              = $13,500

Therefore, Adrian paid a total of $13,500 over the course of 36 months.

(2) In the simple interest formula I = Prt, the letters used represent the following variables:

I: Interest (the amount of interest paid)

P: Principal (the initial amount, or in this case, the car worth)

r: Rate of interest (expressed as a decimal)

t: Time (in years)

(3) To find the rate of interest in percentage, we need more information. The simple interest formula can be rearranged to solve for the rate of interest:

r = (I / Pt) * 100

=====================================================

Explanation:

Laura starts off with a balance of $606.40

This balance is in effect for x days, where x is some positive whole number between 1 and 30.

For the remaining 30-x days, her balance is 606.40-55.25 = 551.15 dollars after making the payment of $55.25

Here's a table to keep track of everything so far

\(\begin{array}{|c|c|c|} \cline{1-3}& A & B\\ \cline{1-3}\text{Interval} & \text{Num Days} & \text{Balance}\\ \cline{1-3}\text{June 1st to June x} & x & 606.40\\ \cline{1-3}\text{June x+1 to June 30th} & 30-x & 551.15\\ \cline{1-3}\end{array}\)

where "Num Days" is shorthand for "number of days".

What we do is multiply the A and B column to form column C like this

\(\begin{array}{|c|c|c|c|} \cline{1-4}& A & B & C\\ \cline{1-4}\text{Interval} & \text{Num Days} & \text{Balance} & \text{A*B}\\ \cline{1-4}\text{June 1st to June x} & x & 606.40 & 606.40x\\ \cline{1-4}\text{June x+1 to June 30th} & 30-x & 551.15 & 551.15(30-x)\\ \cline{1-4}\end{array}\)

Add up the stuff in column C

606.40x+551.15(30-x)

Then divide by 30 to compute the average daily balance

\(\frac{606.40x+551.15(30-x)}{30}\)

That average daily balance is plugged into this formula

\(\text{F} = \frac{\text{ADB}*\text{APR}*\text{n}}{365}\)

where

We are given the following

Plug in \(\text{ADB} = \frac{606.40x+515.15(30-x)}{30}\) and solve for x

So,

\(\text{F} = \frac{\text{ADB}*\text{APR}*\text{n}}{365}\\\\5.71 = \frac{\frac{606.40x+551.15(30-x)}{30}*0.1204*30}{365}\\\\5.71 = \frac{(606.40x+551.15(30-x))*0.1204}{365}\\\\5.71*365 = (606.40x+551.15(30-x))*0.1204\\\\2,084.15 = 606.40*0.1204x+551.15*0.1204(30-x)\\\\2,084.15 = 73.01056x+66.35846(30-x)\\\\\)

\(2,084.15 = 73.01056x+1,990.7538-66.35846x\\\\2,084.15 = 6.6521x+1,990.7538\\\\2,084.15-1,990.7538 = 6.6521x\\\\93.3962 = 6.6521x\\\\6.6521x = 93.3962\\\\x = 93.3962/6.6521\\\\x = 14.0401076351829\\\\\)

That value is approximate.

When rounding to the nearest whole number, we get x = 14.

Therefore, from June 1st to June 14th, Laura has a balance of $606.40

From June 15th to June 30th, she has a balance of $551.15

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

Checking the answer:

Here's the updated table with x replaced with 14. So x+1 = 14+1 = 15

\(\begin{array}{|c|c|c|c|} \cline{1-4}& \text{A} & \text{B} & \text{C}\\ \cline{1-4}\text{Interval} & \text{Num Days} & \text{Balance} & \text{A*B}\\ \cline{1-4}\text{June 1st to June 14th} & 14 & 606.40 & 8489.60\\ \cline{1-4}\text{June 15th to June 30th} & 16 & 551.15 & 8818.40\\ \cline{1-4}\end{array}\)

Adding everything in column C gets us

8489.60+8818.40 = 17,308

Divide that over 30 days

(17,308)/30 = 576.93

Her average daily balance for the month of June is $576.93

Plug that into the formula mentioned to get the finance charge.

\(\text{F} = \frac{\text{ADB}*\text{APR}*\text{n}}{365}\\\\\text{F} = \frac{576.93*0.1204*30}{365}\\\\\text{F} = \frac{2,083.87116}{365}\\\\\text{F} = 5.7092\\\\\text{F} = 5.71\)

We get the correct finance charge of $5.71, so the answer has been confirmed.

bisects x = -12AB / (2AB - 6BD)

m∠ABC = 6x

= 6 × (-12AB / (2AB - 6BD))

To solve for x and find the measure of angle ABC (m∠ABC), we will apply the angle bisector theorem and use the given information.

According to the angle bisector theorem, the ratio of the lengths of the segments created by an angle bisector is equal to the ratio of the measures of the angles formed by the bisector.

Let's set up the equation using the given information:

m∠ABD = 6x (angle ABD)

m∠DBC = 2x + 12 (angle DBC)

Using the angle bisector theorem, we have:

AB/BD = m∠ABD/m∠DBC

Since BD bisects ∠ABC, we can substitute the given measures into the equation:

AB/BD = (6x) / (2x + 12)

To solve for x, we can cross-multiply:

AB × (2x + 12) = BD × (6x)

Expanding both sides of the equation:

2ABx + 12AB = 6BDx

Rearranging the equation:

(2AB - 6BD)x = -12AB

Now we can isolate x:

x = -12AB / (2AB - 6BD)

The measure of angle ABC (m∠ABC), we substitute the value of x back into the expression:

Simplifying this expression further would require additional information about the lengths of AB and BD.

Without this information, we cannot find the exact value of m∠ABC.
