there are 16 appetizers available at a restaurant. From these, janet is to chose 13 for her party. How many groups of 13 appetizers are possible

Answers

Answer 1

Answer:

560

Step-by-step explanation:

The best way to do this is to write it out, but with large ones like this you should use the equation:

C(n,r) = n!/(r!(n-r)!),

where:

C(n,r) is the number of combinations;

n is the total number of elements in the set; and

r is the number of elements you choose from this set.

The art club is designing a rectangular mural for the school hallway. Three
corners are located at (-1,-1),(-1, 1), and (4.1) on a coordinate plane. Find the
fourth vertex and graph the rectangle on the coordinate plane below.
Fourth vertex:

Answers

Answer:

The coordinates are (50, 103)

Step-by-step explanation:

The three hallways are AB, BC, CD.

The co-ordinate of D is (50, 75).

The school's flagpole is 28 meters right of the point D.

Hence the y-coordinate for the flagpole will be same as D, that is 75.

The x-coordinate will be (28 + 75) = 103.

The location of the school's flagpole will be represented by (50, 103)

The 4th vertex of the rectangle is given by D ( 4 , -1 ) and the graph is plotted

What is the Area of a Rectangle?

The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle

Area of Rectangle = Length x Width

Given data ,

Let the area of the rectangle be represented as S

Let the rectangle be represented as ABCD

The coordinates of A = A ( -1 , -1 )

The coordinates of B + B ( -1 , 1 )

The coordinates of C = C ( 4 , 1 )

So , the length of the rectangle = 4 units

The width of the rectangle = 2 units

So , the area of the rectangle S = 4 x 2 = 8 units

And , the 4th vertex of rectangle D = D ( 4 , -1 )

Hence , the coordinate D of rectangle is D ( 4 , -1 )

find a ⋅ b
a = 7i - 4j, b = 4i + 3j

Answers

Answer:

28i^2 + 5ij - 12j^2

Step-by-step explanation:

(7i-4j)(4i+3j)

7i times 4i is 28i^2

7i times 3j is 21ij

-4j times 4i is -16ij

-4j times 3j is -12j^2

In equation it looks like this:

28i^2+21ij-16ij-12j^2

Simplify 21ij and -16ij

21ij-16ij is 5ij

So the answer is:

80 tablespoons of butter for every 32 bananas

Answers

Answer:

Top row: 3 cups, 30 tablespoons, 12 bananas

Second row: 7 cups, 70 tbs, 28 bananas

Step-by-step explanation:

The ratio is 5 (sugar) : 50 (butter)...

You can make the unit rate: 1 cup of sugar: 10 tbs of butter

Since the other ratio is 80 tbs : 32 bananas...

1 tbs : .4 bananas

So...

3 cups : 30 tbs

30 tbs : 12 bananas

28 bananas : 70 tbs

70 tbs :  7 cups

HELP! Please answer fast How many terms are in the geometric series 0.4 + 1.2 + 3.6 + ... + 7,873.2?

Answers

Answer:

10 terms. I think you should check the explanation :)

Step-by-step explanation:

0.4 + 1.2 + 3.6 + ... + 7,873.2?

So I figured that you have to multiply the terms by three to get the next term.

0.4 * 3 = 1.2

1.2 * 3 = 3.6

But, I know it will takes us a really long time to get to 7,873.2, so what I will do is jump 3 sequences.

So if I multiply by 3 to get the next term, I'll multiply by 9 to get the next two terms because 3 * 3 is 9.

So to jump three times, I will multiply by 27 to get the next three terms because 3 * 3 * 3 is 27.

0.4 + 1.2 + 3.6 + ...

3.6 * 27 = 97.2

0.4 + 1.2 + 3.6 + ..., ..., 97.2, ...

97.2 * 27 = 2624.4

0.4 + 1.2 + 3.6 + ..., ..., 97.2, ..., ..., 2624.4, ...

Since we are getting close, I'm going to go back to multiply by 3.

2624.3 * 3 = 7873.2

0.4 + 1.2 + 3.6 + ..., ..., 97.2, ..., ..., 2624.4, 7873.2

Now that we have reached 7873.2, we will now count the terms (count the sets of three dots as terms too).

There are 10 terms in the geometric sequence.

Answer:

Approximately $0.10 per ounce

Step-by-step explanation:

Hi! :) I'm assuming this problem is asking for the price per ounce? If not, I apologize.

So, in order to determine the price of cereal per ounce we would simply divide $3.50 by 36 to find the cost per ounce.

$3.50 / 36 = approximately $0.09722222 which we can round up to $0.10.

What is an equation of the line that passes through the point (6,1) and is perpendicular to the line 2x+3y=18?

Answers

Answer

y = 3/2x -8

Step-by-step explanation:

The first thing you should do is change the equation into slope intercept form. Subtract 2x from both sides to get: 3y = -2x + 18. Divide all parts of the equation by 3 to get your equation in slope intercept: y = -2/3x + 6. One thing you should know when finding the slope of a perpendicular line is that it is the opposite reciprocal. So, the slope is going to be 3/2. This is your current equation: y = 3/2x + b. Plug in the point to the equation, it should look like this: 1 = 3/2(6) + b. Multiply 3/2 by 6 to get 9. This is what it should look like: 1 = 9 + b. Then, subtract 9 from both sides of the equation to get your y-intercept of -8. Go back to your other equation and plug in -8 for b. This is your final equation: y = 3/2x -8.

• The circumcenter is at the intersection of the perpendicular bisectors of the triangle's sides.

• The circumcenter is equidistant fromeach vertex of the triangle.

• The circumcenter is equidistant from each side of the triangle.

Option B is wrong as the circumcenter of an obtuse triangle is not always outside it. For the circumcenter, there is intersection of all the three lines and it's not important that they should always be outside.
