Answer:

The length of o is 24 centimeters

Step-by-step explanation:

In Δ OPQ

∵ Side p is opposite to ∠P

∵ Side q is opposite to ∠Q

∵ Side o is opposite to ∠O

→ To find side o we must use the cosine rule

∴ o = \(\sqrt{p^{2}+q^{2}-2(p)(q).cos(O) }\)

∵ p = 38 cm

∵ q = 29 cm

∵ m∠O = 39°

→ Substitute them in the rule to find o

∴ o = \(\sqrt{(38)^{2}+(29)^{2}-2(38)(29).cos(39)}\)

∴ o = 23.92008154

→ Round it to the nearest centimeter (whole number)

∴ o = 24 centimeters

∴ The length of o is 24 centimeters

The ladder will reach a Height of approximately 43.46 meters on the building.

To find out how high on the building the ladder will reach, we can use the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

In this case, the ladder forms a right triangle with the ground and the building. The base of the ladder is 7 meters, the height of the building is what we need to find, and the length of the ladder is given as 44 meters.

Using the Pythagorean theorem, we can set up the equation:

(Height of the building)^2 + 7^2 = 44^2

Simplifying the equation, we have:

(Height of the building)^2 + 49 = 1936

Subtracting 49 from both sides, we get:

(Height of the building)^2 = 1887

To find the height of the building, we take the square root of both sides:

Height of the building = √1887

Calculating the square root of 1887, we find that the height of the building is approximately 43.46 meters.

Therefore, the ladder will reach a height of approximately 43.46 meters on the building.

Answer: 72.36

Step-by-step explanation:

To find the total amount of salt in the bowl after Omar poured 13.2 grams, we need to add the initial amount of salt in the bowl to the amount of salt Omar added.

The initial amount of salt in the bowl was 59.16 grams.

Omar added 13.2 grams of salt to the bowl.

To find the total amount of salt in the bowl now, we add these two amounts: 59.16 + 13.2 = 72.36

Therefore, the bowl contains 72.36 grams of salt now.

The critical value of f for an upper-tail test at a 0.05 significance level is 2.94.

The critical value of F for an upper-tail test at a 0.05 significance level with a sample size of 21 for the sample with the smaller variance and a sample size of 9 for the sample with the larger variance can be found using an F-distribution table or calculator.

Using an F-distribution table or calculator with numerator degrees of freedom (df1) of 8 and denominator degrees of freedom (df2) of 20 (since df1 is for the sample with the larger variance and df2 is for the sample with the smaller variance), the critical value of F at the 0.05 significance level is approximately 2.94.

Therefore, the answer is a. 2.94.

Answer:

Bridget has $5.55.

Step-by-step explanation:

First let's find how much money Bridget needs to buy 5 vases. To do this, multiply the cost per vase by the amount of vases she wants to buy:

2 * 5 = 10

It would cost $10 to buy 5 vases.

Bridget needs $4.45 in order to buy 5 vases. So, to find how much money she already has, subtract the amount of money she needs from the total cost of the 5 vases:

10 - 4.45 = 5.55

Bridget has $5.55.

Answer:

$ 5.55

Step-by-step explanation:

Find the price of 5 vases

Cost of 5 vases = 5 * 2 = $ 10

She needs $4.45 to buy 5 vases. If we subtract this 4.45 from $10, the result will be the money she has already with her

Money Bridget has = 10 - 4.45

                               = $ 5.55

Foreign direct investment helps improve the economic situation of a recipient country by increasing employment opportunities in the country that the company invests in.

When foreign companies invest in a recipient country, they often establish or expand their operations, which requires hiring local workers. This leads to job creation and reduces unemployment rates in the recipient country.

Increased employment opportunities result in more individuals having access to income and improved standards of living.

Foreign direct investment also contributes to the transfer of technology, knowledge, and skills to the recipient country. Multinational companies often bring advanced technologies, production techniques, and management practices that may not have been available or widely adopted in the recipient country.

Furthermore, foreign direct investment stimulates domestic investment and encourages the growth of local businesses. When foreign companies invest in a recipient country, they often form partnerships or engage in supply chain relationships with local firms.

Overall, foreign direct investment increases employment opportunities, fosters technology transfer, and stimulates domestic investment, all of which contribute to improving the economic situation of a recipient country.

Equations

Ava and Addison are saving for a new cell phone.

Ava starts with $100 and adds $5 each week.

Let's call x to the number of weeks, thus the equation to model the amount of money of Ava's is:

A = 100 + 5x

Addison starts with 200 and adds $4 each week, thus the equation of the money he/she has is:

B = 200 + 4x

We are required to find the number of weeks needed for them to have the same amount of money saved, that is:

100 + 5x = 200 + 4x

Subtracting 4x:

100 + 5x - 4x = 200

Subtracting 100:

5x - 4x = 200 - 100

Operating:

x = 100

Ava and Addison will have the same amount of money saved in 100 weeks

Ava will have: 100 + 5(100) = $600

Addison will have: 200 + 4(100) = $600

Answer:

Step-by-step explanation:

1. Set up an equation

This may be a word problem, but it can definitely be set up into an equation.

For this equation, we can use x as the number.

One-third of x, or x/3

IS (which can also mean equal, =)

12 less than the number itself, x-12

When you put these together you get:
x/3=x-12

We can then solve this equation like normal.

1. Multiply both sides by 3 to cancel the division

x=3x-36

2. subtract 3x on both sides

-2x=-36

3. Now divide each side by -2 to get rid of x's coefficient

x = 18

Test: We can check ourselves to see if this is correct.

1/3 of 18 is 6.

6 is also 12 less than 18.

This proves that 18 is the number.

From the given table, it is found that:

a. The average population decline was of 2,250 deer a year.

b. The population would have reached 225 thousand deer during the years of 2017 and 2018.

The average rate of change of a function is given by the change in the output divided by the change in the input of the function. Hence, over an interval [a,b], the average rate of change is given as follows:

\(r = \frac{f(b) - f(a)}{b - a}\)

In 1984 and 2018, the populations are given as follows:

Hence the rate of change is given as follows:

r = (173.5 - 250)/34 = -2.25.

(2.25 thousand = 2,250).

For item b, the following linear function is built:

y = 230.5 - 1.45x.

The amount would be of 225 when:

230.5 - 1.45x = 225

1.45x = 5.5.

x = 5.5/1.45

x = 3.79.

Hence between the years of 2017 and 2018.

The probability, if Greg gets dressed in the dark, that he winds up wearing the white shirt and tan pants is 0.125 or 12.5%.

To find the probability that Greg winds up wearing the white shirt and tan pants while getting dressed in the dark, we need to find out all the possible outfit options. According to the question given, first we nned to find out number of outfit combinations possible.

Total number of Outfit Combinations:

There are 4 shirts: a white one, a black one, a red one, and a blue one and also two pairs of pants, one blue and one tan. So, total number of possible outfit combinations would be 4 * 2 = 8.

No of favourable options:

As given in the question, Greg wears white shirt and tan pants. There is only one white shirt and one tan pant. So, number of favourable options would be only 1 .

Probability = Number of favourable outcomes/Total no. of combinations

Probability = 1/8

Probability = 0.125 or 12.5%

Therefore, the probability, if Greg gets dressed in the dark, that he winds up wearing the white shirt and tan pants is 0.125 or 12.5%.
