We shall use Trigonometrical Ratio as below:

Making x the subject of the formula, we get

Thus, the distance from the control tower to point A is 80.0 meters.

Part (c)

We are required to find the length of AB= y.

Considering triangle PQB, we have:

Solving for y, we get

Thus, the distance moved by the plane from its initial position is 108.9 meters.

Multiply 3x11/12 and reduce to lowest terms Convert into a mix number ​

we have

3*(11/12)=11/4

11/4=8/4+3/4=2+3/4=2 3/4

First, we need to calculate the value of the monthly payments. We can use the general ordinary anuity formula:

Where PV=$87000

n=20

i=0.06

Replace the given values and solve for PMT:

Now that you have the payment, you can construct the table of the amortization schedule with the know information:

To calculate the missing information, start by calculating the interest component of the payment (interest paid) by multiplying the periodic interest by the remaining principal.

The monthly interest is the yearly interest divided by 12, then:

And the interest paid is then:

Now, calculate the principal paid by subtracting the interest paid from the payment amount:

Then, by putting the values on the amortization schedule:

The remaining principal is 87000-7150.06 (principal paid).

Now for the second payment, calculate the interest paid with the new remaining principal:

And the principal paid is:

The remaining principal is:

Thus:

And for the third month, you apply the same calculations and the amortization schedule is:

ANSWER

KM = 17

EXPLANATION

We have that point L is on the line segment KM.

Let us draw a diagram to represent it:

From the diagram, we see that the length of KM is the sum of the lengths of KL and LM.

This means that:

KM = KL + LM

KM = 12 + 5

KM = 17

That is the value of the length of KM.

we have that

the value of a represent a vertical dilation

so

We stretch the graph in the vertical direction by a scale factor of

Let Larry score x, Michael scored 2x

x + 2x = 18

3x = 18

x = 18/3 = 6 points.

Therefore, Larry scored 6 points. Option A

Given the cost of item =$ 100

If it is discounted 24%

So, the discount will be = 24% of 100 = 0.24 x 100 = $24

The cost after discount = 100 - 24 = $76

If it is marked up 24%

so, the rise will be = 24% of 76 = 0.24 x 76 = $18.24

The cost after marked up = 76 + 18.24 = $94.24

So, the answer is : No, and the cost will be = $94.24

EXPLANATION:

When multiplying and/or dividing fractions, answer if each of the statements below are TRUE or FALSE.

1.The denominators MUST be the same. (FALSE);They can have different denominators for both multiplying and dividing fractions.

2.You must convert mixed numbers into improper fractions before multiplying or dividing.(TRUE) ; This procedure is important so that the operation between fractions is as easy and correct.

3.You can keep mixed numbers when performing multiplication or division.

(FALSE) ; These mixed fractions must be converted to improper fractions to later do the correct multiplication or division.

4.Numerators must be multiplied by numerators and denominators must be multiplied by denominators.​(FALSE); The numerator of the first fraction must be multiplied in a cross by the denominator of the second fraction; the denominators are multiplied by each other.

Assuming that each snack pack has 1 juice box and 1 cheese cracker snack, then Holli can make as much as the lowest quantity of juice boxes or cheese cracker snacks.

Let the triangles represent cheese cracker snacks and squares represent juice boxes:

The smallest pack possible includes one cheese cracker snack and one juice box:

The red ovals represent snack packs. Since there are not enough cheese cracker packs to make 77 snack packs, the maximum amount of packs that can be made is 76.

From the drawing, we can see that each snack pack will have one juice box.

Notice that we have 12 people evenly distributed in a round table (360°).

This way, each person would be

30° from each other.

After the two passes, the soup would have moved 120°, meaning that

It would have moved 4 places.

Now, the person sitting 4 places away from Lacy, if the soup is passed counterclockwise, is Haifa

Therefore, the soup would be in front of Haifa.

Let's fill a table with the first two years, we already know those

So, we need to complete the chart for years 3,4, and 5. We know that in year 3, will receive double the money than we get in year 2, this is 2*$2=$4. Now we write that result on our table.

In year 4 we'll get double the money than in year 3, this is 2*$4=$8

Similarly, in year 5 we get double the money than what we got in year 4: 2*$8=$16

And we have filled in the table!

Now, a bonus, the pattern here seems to be an equation, notice this:

year 1 -> $1 = $2^0

year 2 ->$2 = $2^1

year 3 -> $4 = $2^2

year 4 -> $8 = $2^3

year 5 -> $16 = $2^4

This means that the amount of money we'll receive each year is given by

Where t is the year! (year 1, year 2, etc)

Given that the ratio of the sides of two smaller polygons is 4:5

To Determine: The ratio of the areas

Solution:

Note that if the ratio of the sides of two similar shapes is a : b, then the ratio of their areas would be a² : b²

It was given in the question that the ratio of the sides of two smaller polygons is 4:5. Then, their areas would be

Hence, the ratio of the areas is 16 : 25

By applying the linear pair theorem also, we will have that

Hence,

The value of y= 88°

We have:

Applying properties of logarithms:

Okay, here we have this:

We need to solve the following expression:

Finally we obtain that the result is -11.25.

we are given the following expression:

First, we will subtract 17 to both sides:

We get an expression of the form:

To complete the square we will add and subtract the following term:

Replacing the values:

Therefore, we will add and subtract 36:

Now we associate the first three terms:

Now we factor in the associated terms:

Solving the operations:

Now we solve for "x", first by adding 28 to both sides:

Now we take square root to both sides:

Now we subtract 6 to both sides:

Now we factor 28 as 7*4:

Notice that triangles TUZ and WXV have an angle with the same measure; therefore, we need two additional corresponding similar angles, or two corresponding similar sides, or one side and an angle to prove similarity.

Options A is not possible since it would imply that triangle TUZ has two 90°-inner angles.

Option B states a relation between two sides of triangle TUZ, not between two sides (one of each triangle). Option B cannot be the answer.

According to the figure, angles TUZ and WXV have to be congruent; therefore, option C cannot be the answer.

The only valid alternative is option D, option D is the answer.
