\(2520-1008=1512\)

Answer:

$113.90

Step-by-step explanation:

Find the cost of the meal with sales tax:

90 x 0.075 = 6.525

Add that to the original cost of the meal:

90 +  6.525 = 96.525

Find the cost of the tip:

96.525 x 0.18 = 17.3745

Add the tip to the meal price:

96.525 + 17.3745 = 113.8995

In mathematics, linear programming is a technique for maximizing operations under certain restrictions.

Using the mathematical modeling technique of linear programming, a linear function is maximized or minimized depending on the restrictions it is subjected to. This method has proved helpful for directing quantitative judgments in business planning, industrial engineering, and—to a lesser extent—in the social and physical sciences.

In mathematics, linear programming is a technique for maximizing operations under certain restrictions. Maximizing or minimizing the numerical value is the primary goal of linear programming. It comprises of linear functions that are subject to restrictions in the form of inequalities or linear equations.

( x , y)

So we have

\((0 \: , \: - 7) = ( \frac{ - 2 + x}{2} \: , \: \frac{ - 6 + y}{2} )\)

To find the x and y - coordinates of B , we compare the the x and y coordinates of the left side to the ones on the right

So we have

For the x coordinate

\(0 = \frac{ - 2 + x}{2} \\ 0 = - 2 + x \\ \\ x = 2\)

For the y coordinate

Answer: The average amount of pocket change per person is $2.06.

Step-by-step explanation:

To find the average amount of pocket change per person, we need to first add up all the amounts and then divide by the number of people (which is 7 in this case).

Adding up the amounts: $0.00 + $1.25 + $0.02 + $2.00 + $10.75 + $0.40 + $0.00 = $14.42

Dividing by the number of people: $14.42 ÷ 7 = $2.06 So the average amount of pocket change per person is $2.06.

Answer:

53/100

Step-by-step explanation:

First, we convert the fraction to a decimal number by dividing the numerator by the denominator:

8 / 15 = 0.533

There are two parts to the decimal number above:

Integer Part: 0

Fractional Part: 533

Now, we will make the Fractional Part just two digits (nearest hundredth) by using our rounding rules.*

In this case, Rule I applies, so 8/15 (or 0.533) rounded to the nearest hundredth in decimal format is:

0.53

Next, we will make 8/15 rounded to the nearest hundredth in fraction format. Since you can divide our decimal format answer above by 1 and keep the same value, you can make it like this:

0.53 = 0.53/1

Then, we multiply the numerator and denominator by 100 to get rid of the decimal point:

(0.53 x 100) / (1 x 100) = 53/100

That's it. 8/15 rounded to the nearest hundredth is displayed below (simplified if necessary):

Given the lengths of the two sides and the angle between them, only one triangle can be created under the given circumstances.

1. Given that angle B is 32.5°, side AB is 37 cm, side AC is 26 cm, etc.

2. Calculate side BC using the Law of Cosines:

BC = (2(AB)(AC)cosB) + (AB)(AC)2

3. Input the values that are known: BC = (37 2 + 26 2 - 2(37)(26)cos32.5°)

4. Condense: BC = (1369 plus 676 minus 1848 cos 32.5 °)

5. Determine BC =. (2095 - 1539.07)

6. Condense: BC = 556.93

7. Determine BC as 23.701 cm.

8. Since the lengths of the two sides and the angle between them are specified, only one triangle can be formed under the current circumstances.

By applying the Law of Cosines, we can determine the length of the third side, BC, given that side AB is 37 cm, side AC is 26 cm, and angle B is 32.5°. In order to perform this, we must first determine the cosine of angle B, which comes out to be 32.5°. Then, we enter this value, together with the lengths of AB and AC, into the Law of Cosines equation to obtain BC.BC = (AB2 + AC2 - 2(AB)(AC)cosB) is the equation. BC is then calculated by plugging in the known variables to obtain (37 + 26 - 2(37)(26)cos32.5°). By condensing this formula, we arrive at BC = (1369 + 676 - 1848cos32.5°). Then, we calculate BC as BC = (2095 - 1539.07), and finally, we simplify to obtain BC = 556.93. Finally, we determine that BC is 23.701 cm. Given the lengths of the two sides and the angle between them.

The required length of the guy wire, to the nearest foot is 15 feet.

We can use the Pythagorean theorem to solve for the length of the guy wire. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.

In this case, we can consider the 7-foot pole, the 4-foot distance from the stake to the pole, and the guy wire as the sides of a right triangle. Therefore, the length of the guy wire (the hypotenuse) can be found using the formula:

c² = a² + b²

Where c is the length of the guy wire, a is the 4-foot distance from the stake to the pole, and b is the 14-foot distance from the pole to the tower. Plugging in the given values, we get:

c² = 4² + 14²

c² = 16 + 196

c² = 212

c = √212

c = 14.6

So, the length of the guy wire is approximately 14.6 feet, rounded to the nearest foot, which is 15 feet.

Answer:

The answer for the nearest foot is 36ft long.

Step-by-step explanation:

So first we have to find the hypotenuse of the small triangle which is:

                                     \(a^{2}\)+\(b^{2}\)=  \(c^{2}\)

                                     \(7^{2}\)+\(4^{2}\)=\(c^{2}\)

                                     65 = \(c^{2}\)

                                     ±\(\sqrt{65}\)=\(\sqrt{c^{2} }\)​

                                     8.062... = c

Then we compare the small triangle to the big triangle:Compare the small triangle to the big triangle (in the photo link):

After that we set up a proportion and solve for x:Set up a proportion and solve for x which is:

                                    \(\frac{4x}{4}\)=\(\frac{145.120}{4}\)

                                   \(x=36.280\)

The coupon payment for the bond is $3428.81.The coupon payment for the bond is $3428.81. However, none of the options provided match this value.

To calculate the coupon payment, we can use the formula:

Coupon Payment = Coupon Rate * Face Value

Given that the yield to maturity is 12%, we can determine the coupon rate by dividing the yield to maturity by the number of periods per year. In this case, since the bond matures in 4 years, the number of periods per year is 1. Therefore, the coupon rate is 12% / 1 = 12%.

The face value of the bond is $41,000.

Now, let's calculate the coupon payment:

Coupon Payment = 12% * $41,000 = $4,920

Since the bond is currently selling for $11,050, we can calculate the coupon payment for $4 as follows:

Coupon Payment for $4 = ($4 / $41,000) * $11,050 = $1,070.73

However, the options provided do not match this value. Therefore, the correct answer is not among the options provided.
