The sum between angles a° and c° gives 300°.

Here we want to find the sum of the two angles a° and c°.

First, we can see that a is a plane angle, then:

a° = 180°

We also can see that c° plus the angle at its left which is 60° should be a plane angle, then we can write:

60° + c° = 180°

c° = 180° - 60°

c° = 120°

Now we know the values of c°  and a°, then the sum will give:

a° + c° = 120° + 180° = 300°

That is the answer.

Answer:

2 real solutions

Step-by-step explanation:

Currently, this quadratic equation is in standard form, which is:

[tex]ax^2+bx+c=0[/tex]

We can find the number of real solutions using the discriminant from the quadratic equation which is:

To calculate b, we can plug one of the points into the equation to solve for b. If we plug in (1,2) we get 2 = 1(1) + b, so b = 1. Therefore, the equation of the linear function is y = x + 1.

To find the equation of the linear function represented by the table, we can use the slope-intercept form of a linear equation, which is y = mx + b. To calculate m, we can take two points on the line and calculate the rise (y2 - y1) over the run (x2 - x1). In this case, we can take the points (1,2) and (3,4). The rise is 2 and the run is 2, so m = 1. To calculate b, we can plug one of the points into the equation to solve for b. If we plug in (1,2) we get 2 = 1(1) + b, so b = 1.

Answer:

we can see that the second option, 21 oz for $3.50, has the better value because it costs less per ounce compared to the first option.

Step-by-step explanation:

To calculate the unit rate for each option, we divide the price by the amount of ounces:

For 17 oz for $2.98:

Unit Rate = $2.98 ÷ 17 oz

Unit Rate = $0.175 oz^-1 (rounded to three decimal places)

For 21 oz for $3.50:

Unit Rate = $3.50 ÷ 21 oz

Unit Rate = $0.167 oz^-1 (rounded to three decimal places)

Comparing the two unit rates, we can see that the second option, 21 oz for $3.50, has the better value because it costs less per ounce compared to the first option.

If a ray QT bisects <RQS, then the measure of one  m ∠TQS = 23.5°

Bisector:

In geometry, bisector is the division of something into two equal or equal parts (of the same shape and size). This usually involves a bisector, also called the midline. The most commonly considered bisectors are the bisector (the line passing through the midpoint of a given line segment) and the angle bisector (the line passing through the vertex of the angle, the bisector equal to the angle ).

According to the Question:

Given :

a ray QT bisects <RQS

∠PQR and ∠RQS is a linear pair . It makes and angle 180 degree

m ∠PQR + m ∠RQS = 180

From the diagram,

m ∠PQR = 3x-5, and m ∠RQS= x+1

Substitute the expression and solve for x

     m ∠PQR + m ∠RQS = 180

⇒ 3x-5 + x+1 = 180

⇒ 4x -4 = 180

⇒ 4x = 184

⇒ x = 46

Now ,  

m ∠RQS = x +1

               = 46 +1

               = 47

Given  QT bisects <RQS. it means QT divides RQS equally

   m ∠TQS = m ∠RQS/2

⇒ m ∠TQS = 47/2

⇒ m ∠TQS = 23.5

Step-by-step explanation:

Therefore, it will cost $1.42 to mail a package that weighs 6.8 ounces.

To mail a package that weighs 6.8 ounces, the amount it will cost can be calculated using the given information. The post office charges $0.55 to mail a standard-sized item that weighs an ounce or less, and the charge for each additional ounce (up to 13 ounces), or fraction of an ounce, of weight is $0.15.

Therefore, to mail a package that weighs 6.8 ounces, we can use the following formula:
Cost = $0.55 + (Number of additional ounces) x $0.15

We need to find the cost of mailing a package that weighs 6.8 ounces. We know that the first ounce costs $0.55, and the package weighs 6.8 ounces. Therefore, the number of additional ounces is:
6.8 - 1 = 5.8

We also know that the cost for each additional ounce is $0.15. Therefore, the cost of mailing a package that weighs 6.8 ounces can be calculated as:
Cost = $0.55 + (5.8) x $0.15
Cost = $0.55 + $0.87

The function of given situation is 30x + 40y = 240. The x and y- intercept of function is  (8, 0), (0, 6).

To represent this situation, we can use the following function:

f(x, y) = 30x + 40y

where x is the number of picks and y is the number of shovels.

Since the function represents the total amount spent by Jack, we can set it equal to the given amount:

30x + 40y = 240

To find the x-intercept, we can set y = 0 and solve for x:

30x + 40(0) = 240

30x = 240

x = 8

Therefore, the x-intercept is (8, 0), which means that if Jack buys 8 picks and no shovels, he will spend $240.

To find the y-intercept, we can set x = 0 and solve for y:

30(0) + 40y = 240

40y = 240

y = 6

Therefore, the y-intercept is (0, 6), which means that if Jack buys 6 shovels and no picks, he will spend $240.

Spherical Coordinates:

In mathematics, a spherical coordinate system is a coordinate system in three-dimensional space in which the position of a point is specified by three numbers: the radial distance of the point from a fixed origin, the polar angle measured at from a fixed zenith direction, and its Azimuth orthogonal projection on a reference plane passing through the origin and normal to the vertex, measured from a fixed reference direction on this plane.

According to the Question:

To change the coordinates from rectangular to spherical we have to use these formulae:

The correct options are:

The equation StartFraction 1 over 8 EndFraction (x + 16) = StartFraction 76 over 8 EndFraction represents the situation, where x is the food bill.

The solution x = 60 represents the total food bill.

What is the equivalent expression?

Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.

Since there are 8 friends and they decided to split the bill and tip evenly among themselves, each friend pays an equal share of the total bill, which is the food bill plus the tip. Let x be the food bill.

Then the total bill is x + 16 (the food bill plus the tip), and each friend's share is StartFraction 1 over 8 EndFraction (x + 16).

So, we have the equation StartFraction 1 over 8 EndFraction (x + 16) = StartFraction 76 over 8 EndFraction, which represents the situation where the total bill is $76 and there are 8 friends. Solving for x, we get:

StartFraction 1 over 8 EndFraction (x + 16) = StartFraction 76 over 8 EndFraction

x + 16 = 76

x = 60

Therefore, the total food bill is $60, which is the solution to the equation.

Each friend's share of the food bill and tip is StartFraction 1 over 8 EndFraction (x + 16) = StartFraction 1 over 8 EndFraction (60 + 16) = $9.

The equation 8(x + 16) = 76 is not correct, as it assumes that the total bill is divided equally among 8 people without taking into account the food bill and the tip separately.

hence, The correct options are:

The equation StartFraction 1 over 8 EndFraction (x + 16) = StartFraction 76 over 8 EndFraction represents the situation, where x is the food bill.

The solution x = 60 represents the total food bill.

The mean, median, mode, and range of times for the second week are

Mean: 13.857 hours

Median: 14 hours

Mode: 16 and 10 hours

Range: 8 hours

To find the mean, median, mode, and range for the second week, we first need to calculate the new set of values by adding 6 to each entry in the first week.

New set of values for the second week:

16 14 18 12 11 10 16

Mean

To find the mean, we add up all the values in the set and divide by the total number of values

Mean = (16 + 14 + 18 + 12 + 11 + 10 + 16) / 7

Mean = 97 / 7

Mean = 13.857

Therefore, the mean for the second week is 13.857 hours.

Median

To find the median, we need to arrange the values in ascending order:

10 11 12 14 16 16 18

The median is the middle value in the set. Since there are an odd number of values in the set, the median is the fourth value, which is 14.

Therefore, the median for the second week is 14 hours.

Mode

The mode is the value that appears most frequently in the set. In this case, there are two values that appear twice: 16 and 10. Therefore, the set has two modes.

Therefore, the mode for the second week is 16 and 10 hours.

Range

The range is the difference between the highest and lowest values in the set. In this case, the highest value is 18 and the lowest value is 10.

Therefore, the range for the second week is 18 - 10 = 8 hours.

The pricing structure for the tour company is based on a base price of $60 per person, which is then discounted by $4 for each additional person up to a maximum of 8 people. This means that for a group of 2 people, the price would be $60 + $56 = $116, while for a group of 3 people, the price would be $60 + $52 + $52 = $164.

The pricing structure incentivizes larger groups to go on the tour, as they can benefit from the discounted price per person. However, the discount stops at 8 people, which means that larger groups do not receive any further discounts. This is likely because the tour company may have a limit on the number of people they can accommodate on a single tour.

It is important for customers to be aware of the pricing structure when considering booking a tour with the company.

The ratio of the area of the inscribed circle to the area of the square ABFE is π:2.

If AB is divided into four congruent segments, each of which is the diameter of a semicircle, then we can draw four semicircles such that each one has its diameter on AB and they all have the same radius. Let the radius of each semicircle is r.

Let's assume the radius of each semicircle to be "r" and AB to be equal to "4r" because AB is divided into four congruent segments. Let the center of the inscribed circle be "O". Draw radii from the center of the inscribed circle to the tangent points, and let the tangent points on the semicircles be "C" and "D", and the midpoint of AB be "M".

Since CM and DM are radii of semicircles, they each have a length of "2r". So, MC = MD = 2r. Additionally, since CMDO is a square (as opposite sides are parallel and equal in length), we have CM = MD = CO = DO = 2r.

By the Pythagorean theorem, we have MC² = MO² - OC². Substituting the values we have, we get:

(2r)² = MO² - (2r)²

4r² = MO² - 4r²

MO² = 8r²

The area of the inscribed circle can be calculated as πr², so substituting MO² = 8r², we get the area of the inscribed circle as 8πr².

The area of the square ABFE is (4r)² = 16r².

So, the ratio of the area of the inscribed circle to the area of the square ABFE is:

(8πr²) : (16r²) = π : 2

Therefore, the ratio of the area of the inscribed circle to the area of the square ABFE is π : 2.
