Zachary has 10 9/16 cups of dough to make dumplings. If he uses 13/16 cup of dough for each dumpling, how many dumplings can Zachary make?

Answers

Answer:

Zachary can make 13 dumplings.

Step-by-step explanation:

We know the size of the groups (13/16 cups) and the total (10 9/16 cups of dough). We're trying to find the number of groups that would fit in our total (10 9/16 cups). To find that out, we need to compute:

13\16 x ? =10 9/16

10 9/16 divided by 13/16 = ?

10 9/16 x 16/13

[tex]\displaystyle 21 \approx c[/tex]

Explanation:

Solving for Angles

[tex]\displaystyle \frac{a^2 + b^2 - c^2}{2ab} = cos\angle{C} \\ \frac{a^2 - b^2 + c^2}{2ac} = cos\angle{B} \\ \frac{-a^2 + b^2 + c^2}{2bc} = cos\angle{A}[/tex]

Do not forget to use [tex]\displaystyle arccos[/tex] or [tex]\displaystyle cos^{-1}[/tex]towards the end, or the result will be thrown off.

Solving for Edges

[tex]\displaystyle b^2 + a^2 - 2ba\:cos\angle{C} = c^2 \\ c^2 + a^2 - 2ca\:cos\angle{B} = b^2 \\ c^2 + b^2 - 2cb\:cos\angle{A} = a^2[/tex]

Take the square root of the result in the end, or you will throw yourself off.

What is the area of this triangle?

Enter your answer as a decimal in the box. Round only your final answer to the nearest tenth.


in²

The figure contains a triangle. One side is 13 inches. A second side is 7.5 inches. The angle between the given sides is 94 degrees.

Answers

Answer:

Area = 48.6 in²

Explanation:

The area of the triangle can be calculated using the side-angle-side method as follows:

Area = 0.5 * first side * second side * sin(angle included between the two sides)

This rule is illustrated in the attached image.

Now, we have:

first side = 13 in

second side = 7.5 in

The angle included between the two sides = 94 degrees

The given angle is included between the two given sides, therefore, we can apply the above rule to get the area.

Area of triangle = 0.5 * 13 * 7.5 * sin(94)

Area of triangle = 48.63 which is approximately 48.6 in²

Describe a data set that has the same mean, median, and mode.

I not really understanding this question could somebody help ​

Answers

Answer: Okay, so you probably already know this but,

The mean - is the same as the average value of a data set and is found using a calculation. Add up all of the numbers and divide by the number of numbers in the data set.

Add up all of the numbers and divide by the number of numbers in the data set. The median is the central number of a data set. Arrange data points from smallest to largest and locate the central number.

The mode of a data set is the number that occurs most frequently in the set. To easily find the mode, put the numbers in order from least to greatest and count how many times each number occurs. The number that occurs the most is the mode!

Step-by-step explanation:

In a perfectly symmetrical distribution, the mean and the median are the same. This example has one mode (unimodal), and the mode is the same as the mean and median. In a symmetrical distribution that has two modes (bimodal), the two modes would be different from the mean and median.

hope this helps you!!

Answer:

One of the many examples is {0, 0, 0, 0, 0}

Step-by-step explanation:

The mean is the average of a data set.
The median is the number in the middle (or between the 2 middle numbers) of a data set that is placed from least to greatest.
The mode is the value that shows up the most times in the data set.

A few examples of a set with the same mean, median, and mode could be any number repeated in a data set:
{0, 0, 0, 0, 0}
This would work because the mean is 0, the median is 0, and the mode is 0.

Let the vector v v have an initial point at ( 1 , − 7 ) (1,−7) and a terminal point at ( 3 , − 2 ) (3,−2). Determine the components of vector v . v.

Answers

Answer:  The vector is < 2, 5 >

==========================================================

Explanation:

Label the initial point (1,-7) as point P and (3,-2) as point Q.

The x coordinate of P is 1The x coordinate of Q is 3

This is a change of +2, meaning we move 2 units to the right.

Therefore, the x component of the vector is +2 or simply 2.

The y coordinate of P is -7The y coordinate of Q is -2

This is a change of +5 when moving from P to Q. We have moved 5 units up. The y coordinate of the vector is +5 or simply 5.

Overall, the vector is < 2, 5 > which tells the reader "move 2 units to the right and 5 units up.

Beth currently brings in an annual salary of $37,000 and anticipates a raise of 5% every year. What will her salary be in 14 years? If necessary, round your answer to the nearest cent.

Answers

Answer:
A = $73,257.47

A = P + I where
P (principal) = $37,000.00
I (interest) = $36,257.47

Calculation Steps:
First, convert R as a percent to r as a decimal
r = R/100
r = 5/100
r = 0.05 rate per year,

Then solve the equation for A
A = P(1 + r/n)nt
A = 37,000.00(1 + 0.05/1)(1)(14)
A = 37,000.00(1 + 0.05)(14)
A = $73,257.47

Summary:
The total amount accrued, principal plus interest, with compound interest on a principal of $37,000.00 at a rate of 5% per year compounded 1 times per year over 14 years is $73,257.47.


I hope this helps! :)

Beth salary in 14 years would be $62900.

What is the simple interest?

Simple interest is the borrowing amount added only to the principal amount.

Given, Beth currently brings in an annual salary of $37,000 and anticipates a raise of 5% every year.

To find the interest rate:

The formula to calculate the simple interest is;

                                                 S.I. = P x T x R / 100 ,

Where S.I. is simple interest , P is principal amount, T is time period and R is interest rate in a year.

And according to the question,

P = 37000, T = 14 years and R = 5%

Substituting all the values to the formula,

S.I. = P x T x R / 100

S.I. = 37000 x 14 x 5 / 100

      = 25900

Beth final salary = principal amount + interest rate

                           = 37000 + 25900

                          = 62900

Therefore, Beth salary after 14 years is $62900.

How to find the area of a regular polygon

A polygon is regular when all sides and central angles have the same length.The area of a regular polygon (A) can be found in terms of the number of sides (n) and the apothema (a), whose length is 17, by using the following formula:

A = 0.25 · n · a² · tan (180/n)     (1)

If we know that n = 8 and a = 17, then the area of the regular octagon is:

How to find angles in a triangle?

The interior angles of the triangle are given as m∠A = 3x and m∠B = 50°.

The exterior angle of the triangle is given as m∠ACD = 5x.  

The sum of angle in a triangle is equals to 180 degrees. Therefore,

3x + 50 + (180 - 5x)  = 180

3x + 50 - 5x + 180 = 180

3x - 5x + 50 + 180 = 180

-2x + 230 = 180

subtract 230 from both sides

-2x + 230 - 230 = 180 - 230
