The angle that is an obtuse angle (that is, greater than 90° but less than 180°) is 120°. The correct option is B. 120°

An obtuse angle is an angle that is greater than 90° but less than 180°. Thus, if x is an obtuse angle, the range of values for x are

90° < x < 180°

From the given question, we are to determine the angle which obtuse.

In the given figure, to determine the angle which is obtuse, we will determine the angle that is greater than 90° but less than 180°.

The angle that is greater than 90° but less than 180° is 120°.

Thus,

if A C B, then A n B = A U B is always true

The statement "if A C B, then A n B = A U B" can be rephrased as "if A is a subset of B, then the intersection of A and B is equal to the union of A and B".

Every element of A is also an element of B. Therefore, the intersection of A and B contains all the elements of A.

On the other hand, the union of A and B contains all the elements of A and all the elements of B. Since A is a subset of B, all the elements of A are already included in B, so the union of A and B is just equal to B.

Therefore, we have:

A n B = A (since all the elements of A are in both A and B)

A U B = B (since A is a subset of B)

So A n B = A U B = B, which means that the original statement "if A C B, then A n B = A U B" is true

Answer:

3310.9

Step-by-step explanation:

The angles that you get when a circle is divided into 4 equal parts, would be four 90 degree angles.

The reason these angles are called 'right angles' is because they create an exact 90-degree angle, signifying one fourth of a complete circle. Every specific angle is named as a 'quadrant,' as it covers a quarter or a quadrant of the circle.

These four perpendicular angles stand side by side - having in common not just one diameter of the circle but also a shared vertex, which is at the center of the circle. Together, they share uniformly the circle into four unique sections - each turning toward a distinct quadrant of the circle parallel to their placement.

The distance between the areas of the two states is A = 1.727 x 10⁵ km²

Given data ,

Let the area of Nebraska = 2 x 10⁵ km²

Let the area of Massachusetts = 2.73 x 10⁴ km²

The difference between the areas of Nebraska and Massachusetts A =  the area of Nebraska - the area of Massachusetts

On simplifying the exponents , we get

A = 2 x 10⁵ km² - 2.73 x 10⁴ km²

Taking the common factor , we get

A = 10⁴ ( 20 - 2.73 )

A = 10⁴ ( 17.27 )

A = 1.727 x 10⁵ km²

Step-by-step explanation:

Since t is the number of years since 1910, we can find the t value we need for the equation by subtracting 1910 from 1980:

t = 1980 - 1910 = 70

Now, we can plug in 70 for t to find the amount of currency in 1980:

[tex]M(t)=2.08(1.06)^t\\M(70)=2.08(1.06)^7^0\\M(70)=122.8779348\\M(70)=122.88[/tex]

Thus, the amount of currency in 1980 according to the model was $122.88 billion

The volume of the triangular prism in the diagram is 10.5 in³

From the question, we are to calculate the volume of the the given prism.

The given prism is a triangular prism.

Volume of a triangular prism = Area of triangle × Height of prism

Thus,

Volume of the triangular prism = 1/2 × Base of triangle × Height of triangle × Height of prism

From the given diagram,

Base of triangle = 2 in

Height of triangle = 1.5 in

Height of prism = 7 in

Volume of the triangular prism = 1/2 × 2 in × 1.5 in × 7 in

Volume of the triangular prism = 10.5 in³

The dolphin's weight that differs most from the value predicted by this model is JoJo's (31 lb of difference)

Let's elaborate the model this way:

Snowflake's length - Pax's length = 8.2 - 7.6 = 0.6 ft

Snowflake's weight - Pax's weight = 549 - 519 = 30 lb

Ratio = 30/0.6 = 50 lb/ft

This means that for every foot of length, the dolphin has a variable weight of 50 lb.

However, if we multiply the ratio by the actual length of the two dolphins, we will have these results:

Snowflake = 50 × 8.2 = 410

Pax = 50× 7.6 = 380

Snowflake = Actual weight - Ratio× Length = 549 - 410 = 139

Pax = Actual weight - Ratio × Length = 519 - 380 = 139

The common difference is 139.

Therefore, the linear model that predicts the weight (y) of a dolphin given its length (X) is:

y = 139 + 50x

Now, let's use the linear equation or model to calculate the weight of the remaining four dolphins, as follows:

Blaze  y = 139 + 50 × 6.8 = 479 ⇒ difference of 9 lb (488 - 479)

JoJo   y = 139 + 50 × 5.8 = 429 ⇒ difference of 31 lb (460 - 429)

Corky   y = 139 + 50 ×8.4 = 559 ⇒ difference of 2 lb  (559 - 557)

Shadow  y = 139 + 50 × 7.4 = 509 ⇒ difference of 8 lb  (509 - 501)

Hence, the dolphin's weight that differs most from the value predicted by this model is JoJo's (31 lb of difference)

The net sales, =$20.98

The Goods available for sales= $2,045

The total cost of Goods sold=$1,955

Gross profit =$1,934.02

Net income = $1,395.98

The operating income (sales) = $7,240

The return on sales (ROS) = $345

The net sales (revenue generated) = ?

But ROS = operating income/net sales

Net sales = 7240/345;

= $20.98

The goods available for sale = beginning inventory+ new purchase = $725+$1320 = $2,045.

The total cost of Goods sold = Beginning inventory+goods available for sale - end inventory.

= 725+2,045- 815

= 2770-815

= $1,955

The gross profit = cost of goods sold (COGS) - total revenues.

= $1,955-$20.98

= $1,934.02

Net income = total operating expenses - gross profit

operating expenses = 1,750+1000+280+150+150 = $3,330

In mathematics, the expression "to the power of" pertains to the exponent, signifying how many times a key number is to be multiplied by itself.

Expressing this idea in English can be done well by using the term "to the power of." To show this, 2 raised to the third power can be interpreted as 2 multiplied by itself three times, resulting in 8.

Therefore, the possible reason behind using the word "power" is probably due to the fact that when the exponent rises, the outcome number is wide, either being greater or smaller, made on the base being above or below 1. This implies that the figure holds more significant value.

Step-by-step explanation:

To dilate the square by a factor of 1111 from the origin, we need to multiply each coordinate by 1111.

The coordinates of point C are (8,8). So, to find the coordinates of point C' after dilation, we can simply multiply each coordinate by 1111:

x-coordinate of C' = 1111 * 8 = 8888

y-coordinate of C' = 1111 * 8 = 8888

Therefore, the coordinates of point C' are (8888, 8888).

The minimum time required to depreciate the value of the car is 12 years.

Let us assumed the time to be t. Representing the formula for calculation of time-

[tex] {(0.8575)}^{t} [/tex] = 3000/18700

Cancelling zeroes common in numerator and denominator

3000/18700 = [tex] {(0.8575)}^{t} [/tex]
