Answer:

x = 48°

Step-by-step explanation:

42 + 90 + x = 180 (we can tell because it is a straight line and straight lines are supplementary, ie = 180)

Rearrange the equation so that x is on one side:

x = 180 - 90 - 42

Simplify

x = 48°

Answer:

68°

Step-by-step explanation:

x+42+90=180

x+132=180

x=180-132

x=68°

The minimum number of tables that the store must sell in order to meet the requirements is 9 tables.

A system of inequality is a set of inequalities in which we perform the operations to find the range of the solution.

Given that, an online furniture store sells chairs for $100 each and tables for $550 each. Every day, the store can ship at most 21 pieces of furniture and must sell no less than $5700 worth of chairs and tables. If 10 chairs were sold, we are asked to determine the minimum number of tables that the store must sell in order to meet the requirements.

Let x be the number of chairs sold and y be the number of tables sold.

Chairs are sold for $100 each, then x chairs cost $100x.

Tables are sold for $550 each, then y tables cost $550y.

Every day, the store can ship at most 21 pieces of furniture, then,

x+y ≤ 21

Store must sell no less than $5,700 worth of chairs and tables, then

100x+550y ≥ 5700

If 10 chairs were sold, then x=10 substitute this value into both inequalities:

100·10+550y ≥ 5700

\(8\frac{6}{11}\) ≤ y ≤ 11

Hence, the minimum number of tables that the store must sell in order to meet the requirements is 9 tables.

The number of regions created when constructing a Venn diagram with three overlapping sets is 8.

In a Venn diagram, each set is represented by a circle, and the overlapping regions represent the elements that belong to multiple sets.

When three sets overlap, there are different combinations of elements that can be present in each region.

For three sets, the number of regions can be calculated using the formula:

Number of Regions = 2^(Number of Sets)

In this case, since we have three sets, the formula becomes:

Number of Regions = 2^3 = 8

So, when constructing a Venn diagram with three overlapping sets, there will be a total of 8 regions formed.

Each region represents a unique combination of elements belonging to different sets.

These regions help visualize the relationships and intersections between the sets, providing a graphical representation of set theory concepts and aiding in analyzing data that falls into multiple categories.

Therefore, the correct answer is 8.

When two dice are tossed, the event A represents the event of getting a sum of 12. We need to determine the number of outcomes that satisfy this event.

To find the number of outcomes of event A, we can enumerate all possible outcomes when two dice are tossed. Each die has six sides numbered from 1 to 6.

When we roll the first die, there are six possible outcomes: 1, 2, 3, 4, 5, and 6. For each outcome of the first die, there is a corresponding outcome of the second die that, when added together, will result in a sum of 12.

The possible outcomes that satisfy event A are (6, 6) since 6 + 6 = 12.

Therefore, the number of outcomes of event A is 1.

Answer: 1.8 L/h

Step-by-step explanation:

To convert the rate of water dripping from a tap from millilitres per second (ml/sec) to litres per hour (L/h), we need to use conversion factors.

Step 1:

First, let's convert the rate from millilitres per second to litres per second.

There are 1000 millilitres in a litre, so we can divide the rate in millilitres per second by 1000 to get the rate in litres per second:

\(\LARGE \boxed{\textsf{0.5 ml/sec $\div$ 1000 = 0.0005 L/sec}}\)

Step 2:

We can convert the rate from litres per second to litres per hour. There are 3600 seconds in an hour, so we can multiply the rate in litres per second by 3600 to get the rate in litres per hour:

\(\LARGE \boxed{\textsf{0.0005 L/sec $\times$ 3600 = 1.8 L/h}}\)

Therefore, the rate of water dripping from the tap is 1.8 L/h.

Note that we can compare which one is faster using the velocity or the speed of two items.

Speed is distance divided by the time.

For the Infinite Dimension :

The speed is 18.

For the Rise over run's

Slope is the same as distance divided by the time.

So the speed is 24

In this problem we examine two stochastic processes for a stock price: PROCESS A:  the variance of the instantaneous return is constant per unit time. and  in PROCESS B, the variance of the instantaneous return per unit time is not constant but depends on the value of s(t).

In PROCESS A, the instantaneous return is given by dS/S, which represents the change in the stock price relative to its current value. Since PROCESS A is a “driftless” geometric Brownian motion, the change in stock price, ds, is proportional to the stock price, S, and the Wiener process, dw. Therefore, we can write ds = oSdw.

To determine the variance of the instantaneous return, VAR[ds/S], we need to compute the variance of ds and divide it by S². The variance of dw is constant and independent of time, which means it does not depend on the stock price or the time step. As a result, when we divide the constant variance of dw by S², we obtain a constant variance for the instantaneous return VAR[ds/S]. Hence, in PROCESS A, the variance of the instantaneous return is constant per unit time.

However, in PROCESS B, the situation is different. The process ds = aS²dw has an additional term, S², which means the change in stock price is now proportional to the square of the stock price. Since the variance of dw is constant, dividing it by S² will yield a variance of the instantaneous return that depends on the current stock price, S(t). As the stock price changes, the variance of the instantaneous return will also change, reflecting the nonlinear relationship between the stock price and the change in stock price in PROCESS B. Therefore, in PROCESS B, the variance of the instantaneous return per unit time is not constant but depends on the value of s(t).

Answer:

#13. line QR is 26.

#14. a) x = 2 b) m = 6

Step-by-step explanation:

13. We can use the Pythagorean therom: a^2 + b^2 = c^2

We will substitue PQ for a and PR for b

10^2 + 24^2  = c^2

100 + 576 = c^2

100 + 576 = 676

Then, we find the square root of 676, which is 26.

14. a) 3(2x -1) = 9

we first use distributive property:

6x - 3 = 9

then we add 3 to both sides to counteract the -3:

6x = 12

we divide both sides by 6 to get x alone:

x = 2

b) 3m - 12 = 6

we add 12 to both sides to counteract the -12:

3m = 18

we divide both sides by 3:

m = 6

Step-by-step explanation:

You want to draw the triangle with vertex coordinates (2, 1), (3, 3), and (5, 1), along with its rotation 180° about the origin.

The coordinate pair (2, 1) means the point is located 2 units to the right of the y-axis (where x=0), and 1 unit above the x-axis (where y=0). This point is incorrectly plotted in images 2 and 4, eliminating those possibilities.

Rotation 180° about the origin causes the signs of each of the coordinates to be reversed (negated, become the opposite of what they were). That means point (2, 1) gets rotated to the location (-2, -1).

This rotated point is 2 units left of the y-axis, and 1 unit down from the x-axis. It is correctly located in image 3.

Additional comment

Rotation 180° about a point is equivalent to reflection across that point. The segment between a point and its image will have the center of rotation as its midpoint.

Answer:

Susie reaches the store first being ahead by 0.06 hours.

Step-by-step explanation:

20 miles going 45 miles/hour.

20 miles / (45 miles / hour) = 20 miles hours / 45 miles =

= 20 hours / 45 = 4/9 hours = 0.44 hours

25 miles going 50 miles/hour.

25 miles / (50 miles / hour) = 25 miles hours / 50 miles =

= 25 hours / 50 = 1/2 hours = 0.5 hours

So Susie needs less time (= arrives first).

the difference is 0.5 - 0.44 = 0.50-0.44 = 0.06 hours

as additional practice :

0.06 hours is 60 × 0.06 minutes.

60 × 0.06 = 60 × 6 / 100 = 360 / 100 = 3.6 minutes.

Step-by-step explanation:

formula for areas of rectangles= width x height

width=x-5

height=x+5

(x-5)(x+5)= \(x^{2}\)-5x+5x-25

since the 5x's cancel out each other

The area of rectangle is \((x^{2} -25)\) unit square.

The area of rectangle is product of length and width.

         \(Area = length*width\)

Given that length is \((x+5)\) and width is \((x-5)\).

When you change the shape of the clay and put it back in the same amount of water, the total volume will remain the same because it is determined by the volume of the clay, not its shape.

When you submerge a piece of clay in water and measure the total volume, you are essentially measuring the volume of both the clay and the water it displaces.

The clay has a certain volume, and when it is placed in water, it pushes the water aside and takes up space.

Now, if you change the shape of the clay and put it back in the same amount of water, the total volume will remain the same. This is because the amount of water displaced by the clay is determined by its volume, not its shape.

So, even if you change the shape of the clay, it will still displace the same amount of water and have the same total volume.

Let me give you an example to help illustrate this. Imagine you have a cube of clay with a volume of 10 cm³. When you place this cube in water, it displaces 10 cm³ of water.

If you then reshape the clay into a sphere, it will still displace the same amount of water, 10 cm³, because the total volume of the clay hasn't changed.

In summary, when you change the shape of the clay and put it back in the same amount of water, the total volume will remain the same because it is determined by the volume of the clay, not its shape.
