Let's see the facts:

The angles of symmetry in point A is 60 degrees because the plane in point A is divided in 6 parts, so dividing 360° by 6 give us 60°. The same reasoning applies for the point B dividing it by 3 parts.

The angles of symmetry in point B is 120 degrees.

The length of AC is given by AE + EC

According to the Pythagorean Theorem, we know that:

AE² = AD² - ED²

AE² = 5² - 3²

AE² = 25 - 9

AE² = 16

AE = 4

EC² = DC² + ED²

Since DC = BC, we have:

EC² = BC² + ED²

EC² = 45 - 9

EC² = 36

EC = 6

Therefore, AC = 4 + 6 = 10

The total area for the parallelogram-shaped tiles Felix needs to buy exists 80cm² at the price of $40.

In calculating the area of a parallelogram, the base exists multiplied by the height, in an exact way as computing the area of a rectangle.

Given that, the base of one parallelogram-shaped tile exists 4cm with a height of 2 cm.

Area of one parallelogram shaped tile = 4cm × 2cm

Area of one parallelogram-shaped tile = 8cm²

Total area for the 5black and 5white tiles = 10 × 8cm²

Total area for the 5black and 5white tiles = 80cm²

Therefore, Felix must buy a total area of 80cm² of 10 parallelogram-shaped tiles.

Answer:

All of them work.

Step-by-step explanation:

An invertible function can be tested for by the horizontal line test. An function is not invertible is a horizontal line drawn anywhere crosses two or more points. A straight line is an invertible function as long as the slope is not equal to 0. With that, let's check A. From x = -6 to -4, the horizontal line test does not cross two points anywhere. A works. Let's check B. B also works because it passes the horizontal line test. C also works.

She cannot afford to buy the car with monthly instalments of $350. She needs to make a downpayment of $856.44 to afford the car

The total amount of the car loan = 13456.44

Number of instalments = 36 monthly payments

Affordable installment per month = $350

EMI: A fixed payment is made by a borrower to a lender at a specific time each month, known as an equated monthly instalment (EMI). The loan is repaid in full over a predetermined period of time by making equal monthly payments to the principal and interest.

Total payment that can be made using the instalments = Monthly instalments * Number of instalments

= 350*36

Total payment that can be made using the instalments = 12600

The amount remaining after paying instalments = 13456.44 - 12600

= 856.44

Downpayment required = $856.44

The amount of money should be invested to obtain interest of amount 50000$ is 34,000$(approximately)

The practice of adding interest to the principal amount of a loan or deposit is known as compound interest, sometimes known as interest on principal and interest. Reinvesting interest, or adding it to the lent capital rather than paying it out or seeking repayment from the borrower, results in interest being received on the principal amount plus interest collected previously.

[tex]{\displaystyle A=P\left(1+{\frac {r}{n}}\right)^{nt}}[/tex]

Where,A is the total sum.

P equals the initial principal amount.

The nominal yearly interest rate is r.

The compounding frequency is n.

t is the total amount of time that the interest is charged (expressed using the same time units as r, usually years).

The final value less the beginning investment yields the entire compound interest.

On substituting the values we get that initial investment of approximately 34000$

Answer:

242.

Step-by-step explanation:

Basically, you have to put the 2 numbers "1936" and "8" down. After you put the 2 numbers down, you have to figure out how many times 8 goes into 19 which is 2 times.

You put the 2 above the 1 in 1936. After you put the 2 up there, you have to figure out 2 x 8 which is 16. You have to put the 16 below the 19 and subtract 19 by 16 which is 3.

After you finish that equation, you must bring the 3 down next to the 3 you wrote down on 19 - 16. The number turns into 33 and you have to figure out how many times 8 goes into 33 which is 4 times. You put the 4 next to the 2 above and then do 4 x 8 which is 32. You do 33 - 32 which is 1.

You bring the 6 down in 1936. It turns into a 16. You now have to figure out how many times 8 goes into 16 which is 2 times. You put 2 next to the 2 and the 4 above and that turns the number into 242.

You then have to do 2 x 8 which is 16 and put 16 under the 16 from 33 - 32. That'll make an equation which is 16 - 16 which is 0. There is no remainder and all the numbers were added above so 242 is your answer.

Given data:

Population Mean = 346

Standard Deviation = 72

Expected Value of e(x) = population mean = 346

Sample Size = 216

In this case, if many random samples of 216 are taken, then the mean of the sample mean numbers per week is 346. (Option C)

To solve for the variance of x or var(x), we follow the formula below:

In this case, the given standard deviation is 72 and the sample size is 216. Therefore, we have:

One of the properties of the Sampling Distribution of the Mean is that the sampling distribution of the mean is approximately normally distributed so long as the sample size is 30 or higher. Our sample mean here is 346 with a sample standard deviation of √24 or 4.899.

How likely is it to observe a sample mean number of sags per week that exceeds 390?

For this one, we have this formula to use:

Our bar "x" is 390. The "myu" symbol is our population mean which is 346. This σ symbol is the population standard deviation 72 and n is our sample size = 216.

Under a normal curve, the areas defined are between z = -3.5 to z = +3.5. Since our z should exceed > 8.98 and thus far greater than +3.5, then we can say that the probability of having a sample mean that exceeds 390 is zero.

The tanker has been filling the reservoir for 0.0288 minutes or 1.728 seconds as the rate of filling is 1212 gallons per minute using the estimation concept.

As per the question statement, A tanker truck fills the gas station’s reservoir at the rate of 1212 gallons per minute and the reservoir was empty and it is now 35 gallons full. We are supposed to find out for how long has the tanker been filling the reservoir. We will use the concept of estimation.

Rate of filling gas = 1212 gallons per minute

i.e., 1212 gallon of gas taken 1 minute for transfer.

1 gallon of gas will take = (1/1212) minutes

Hence 35 gallons of gas will take = (1/1212)*35 minutes = 0.0288 min.

So, the  tanker has been filling the reservoir for 0.0288 minutes or 1.728 seconds as the rate of filling is 1212 gallons per minute.

EXPLANATION

Let's see the facts:

Plan A --> $35 + $0.25/minute

Plan B --> $20 + $0.5/minute

Let's call "x" to the number of minutes that a person could talk.

Here we have two equations as follows:

(1) 35 + 0.25x

(2) 20 + 0.5x

Where x represents the number of minutes a person talks on the phone.

We need to equal both equations in order to obtain the same cost.

35 + 0.25x = 20 + 0.5x

Now, we need to solve this equality as shown as follows:

-Subtracting -35 to both sides:

35 + 0.25x -35 = 20 + 0.5x -35

-Adding similar terms:

0.25x = 0.5x - 15

-Subtracting -0.5x to both sides:

0.25x - 0.5x = -15

-Adding similar terms:

-0.25x = -15

-Dividing both sides by -0.25:

x = -15/-0.25

-Simplifying:

x= 60 minutes

So, when a person talks for 60 minutes the cost of both plans is the same.

Simple interest is a method of calculating the interest charge. Simple interest can be calculated as the product of the principal amount, rate, and period.

Simple Interest = (Principal × Rate × Time) / 100

If the initial amount (also called as principal amount) is given as 30, and the interest rate is 15% annually, and it is left for 4 months for that simple interest, then the interest amount earned is given by:

4 month = 0.333 year

Therefore,

Simple Interest = (Principal × Rate × Time) / 100

Simple Interest = (30 × 15× 0.333) / 100

Simple Interest = 31.50

Hence, the money she will have after 4 months would be 31.50 dollars.

Step-by-step explanation:

- General linear equation of a line passing through point (x, y) with a gradient m and y-intercept (0, c) is ;

[tex]{ \rm{y = mx + c}}[/tex]

- As finding gradient, m; consider points (0, -3) and (3, 2) from the graph;

[tex]{ \rm{slope \: m = \frac{2 - ( - 3)}{3 - 0} }} \\ \\ { \rm{m = \frac{5}{3} }}[/tex]

- Consider point (0, -3), relate it with (0, c) hence c is -3;

[tex]{ \rm{y = \frac{5}{3}x - 3 }}[/tex]

- If you see the format of the coordinates, x coordinates are greater than y coordinates, hence y < x
