(100 POINTS!) The measures of the exterior angles of an octagon are x°,2x°,3x°,4x°,5x°,6x°,7x°, and 8x°. Solve for X.

The value of ∠C is 73 degrees.

A triangle is a three-sided polygon that consists of three edges and three vertices.

We need to find the value of ∠C

the value of ∠A is 59 degrees and  the value of ∠B is 48 degrees.

We know that from angle sum property the sum of three angles is 180 degrees.

∠A+∠B+∠C=180

59+48+∠C=180

107+∠C=180

Subtract 107 from both sides

∠C=180-107

∠C=73 degrees.

Hence, the value of ∠C is 73 degrees.

Answer:120

Step-by-step explanation:

The mass of the sample after four days is 1.75 kg.

The decay rate for a radioactive substance follows the exponential decay formula:

m(t) = m₀ * e^(-kt),

where m₀ is the initial mass, m(t) is the mass at time t, k is the decay rate parameter, and e is the base of the natural logarithm.

Given that the initial mass of the sample is 2.05 kg and the decay rate parameter is 4% per day, the formula becomes:

m(t) = 2.05 * e^(-0.04t).

To find the mass after four days, we substitute t = 4:

m(4) = 2.05 * e^(-0.04 * 4)

m(4) = 1.75 kg

The coordinates of point T' after Ry-axis is (2, 5) and the coordinates of point T' after Rx-axis is (-2, -5). The solution has been obtained by using the concept of reflection.

What is reflection?

In geometry, a reflection is referred to as a flip. In a reflection, the shape is reflected. An image will reflect over a line known as the line of reflection.

We are given a point T(-2, 5)

In order to find the coordinates of the reflection of  point in the y-axis, we need to change the sign of abscissa i.e., x-coordinate and retain the ordinate i.e., y-coordinate.

So, we get the image of (-2 , 5) as (2, 5)

Thus, the coordinates of point T' after Ry-axis is (2, 5).

When we reflect across the x-axis, the x-coordinate remains the same, but the y-coordinate is taken to be the additive inverse.

So, we get the image of (-2 , 5) as (-2, -5).

Thus, the coordinates of point T' after Rx-axis is (-2, -5).

Hence, the coordinates of point T' after Ry-axis is (2, 5) and the coordinates of point T' after Rx-axis is (-2, -5).

The probability that at least one of the codes will have repeating digits is 0.4712.

The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

Here, The probability of a pin being repeated is 14.7%

⇒ 14.7/100

After Eliminating the decimal point;

⇒ 14.7/100 = 147/1000

Hence,

The probability that a pin, if selected will have a repeating digit format = 147/1000

The probability of a pin not having repeating digits format is,

⇒ 1 - 147/1000

⇒ 853/1000

If four codes are selected at random (without replacement), the probability that all four of the codes will not have repeating digits format is,

⇒ (853/1000) x (852/999) x (851/998) x (850/997)

⇒ 0.5288

Thus, The probability that at least one of them will have repeating digits is,

⇒ 1 - 0.5288

The number of solutions that the system of equations has is given as follows:

The system of linear equations represented in the graph have

The first step in obtaining the number of solutions of the system of equations is obtaining the linear function that represents each line.

The slope-intercept definition of a linear function is given as follows:

y = mx + b.

In which:

m is the slope.

b is the y-intercept.

here, we have,

The first line goes through these following points:

(0,3) and (3,4).

The slope is given by change in y divided by change in x, hence:

slope = 3

When x = 0, y = 3,

hence the intercept is of b = 3

and the function is given as follows:

y = 3x - 3

The second line goes through these following points:

(0,-2) and (3,-1).

Hence the slope is of:

m = 3

The intercept is of b = -2,

and the equation is given as follows:

y = 3x-2.

Hence the solution is obtained as follows:

A 59 gal water tank hold will hold 492 lb of water.

The first step is to determine how many lb of water a 1 gal hot water tank can hold. In order to determine this value, divide 350 by 42.

Division is the process of grouping a number into equal parts using another number. The sign used to denote division is ÷.

Weight of water in a 1 gal water tank = 350 / 42 = 8.333 lb

Now, multiply the value gotten in the previous step by 59.

Weight of water in a 59 gal water tank = 8.333 x 59 = 492 lb

The exact weight of the object is 83.0N

Weight is the force with which a body is attracted toward the earth or a celestial body by gravitation and which is equal to the product of the mass and the local gravitational acceleration. Weight is a vector quantity and it is expressed as :

weight = mass × acceleration due to gravity

acceleration due to gravity is constant on a planet. On earth the acceleration due to gravity is 10m/s².

The mass of the object is 8.30grams

The weight of the object = 8.30 × 10 = 83N

The number of items on their grocery shopping list given the percentage already bought is 20 items.

Percentage of items bought already= 60%

Number of items bought already= 12

Total number of items on the list= x

Number of items bought already = Percentage of items bought already × Total number of items on the list

12 = 60% × x

12 = 0.6 × x

12 = 0.6x

Answer:36

Step-by-step explanation:

The delivered price (including freight) of the living room set is $2858.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

List Price = $5800

Trade  discount = 50%

So, Price after discount

= $5800 - 50% x $5800

= 5800- 2900

= $2900

if Levin pays within 10 days he will have a discount of 3%, So,

3% x $2900

= $87

Thus, the Delivered price = $2900 -$87+ freight charges ( shipping)

                                           = $2900 -$87 + $45 =$2858

Angle geometry is a branch of mathematics that deals with the study of angles and their properties in two-dimensional figures such as circles, triangles, and polygons.

NUMBER 25

x = 53° (alternate angles)

x + y + 49° = 180° (sum of angles in a triangle is 180°)
