Answer:

28.27cm³

Step-by-step explanation:

Area of a circle:

[tex]A=\pi r^2[/tex]

First, find the area of a full circle with this given radius:

[tex]\rightarrow A=(3.14159)(6)^2\\\rightarrow A=(3.14159)(36)\\\rightarrow A=113.09734\\[/tex]

Now, to find the radius of a quarter circle with the same radius, just divide by 4:

[tex]\rightarrow A = \frac{113.09734}{4}\\\rightarrow A = 28.27433[/tex]

The radius of the quarter circle is about 28.27cm³

Answer:

[tex]y=\frac{4}{7} x-\frac{9}{7}[/tex]

Step-by-step explanation:

The yellow points are on (4,1) and (8,8).

The slope is [tex]\frac{8-4}{8-1} =\frac{4}{7}[/tex]

In point-slope form the equation is y-1=[tex]\frac{4}{7}[/tex](x-4)

Expand and add 1 to get y=[tex]\frac{4}{7}[/tex]x-[tex]\frac{9}{7}[/tex]

Answer:

4 people

Step-by-step explanation:

you can set up a proportion based on number of people to the area of the space

area of a 6 by 8 feet space = 48

so 3 is to 48 as 'n' is to 70

3/48 = n/70

1/16 = n/70

16n = 70

n = 70/16 or 4, rounded to a whole number

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

Explanation:

The notation A U B means "set A union with set B". To union two sets, we combine them as one big set.

For example, {1,2,3} union with {a,b,c} becomes {1,2,3,a,b,c}

So {2,3,4,5} U {0,3,6,10,12} = {2,3,4,5,0,3,6,10,12} which sorts to {0,2,3,4,5,6,10,12}. Notice I tossed out that duplicate "3". We only list each unique value once

--------------------

A n B = intersection of A and B

We're looking for the numbers that are in both sets at the same time. In this case, only "3" is in both sets.

So A n B = { 3 }

Even though we have one value, we still use curly braces to denote we have a set.

--------------------

Now to compute A - B

Start with set A = {2, 3, 4, 5}

The erase any values that are found in set A n B. So we'll erase the "3"

Therefore, A-B = { 2, 4, 5}

This is basically another way of saying "start with set A, then kick out anything found in set B".

--------------------

Lastly, to compute B - A, we follow these steps

Start with B = {0, 3, 6, 10, 12}

Erase the items found in A n B = { 3 }

Therefore, B - A = { 0, 6, 10, 12 }

Answer:

30%

Step-by-step explanation:

One simple way of finding out discounts is to simplify our answer by starting with 10% and subtracting from that.

If the original price were to have a 10% discount, it would be 4.70/10 for .47 per 10% off.

10% gives us 4.23, so let's take another 10% off by doing 4.23-.47, which is equal to 3.76. While lower, it's not our answer so lets do another 10%

3.76-4.7 = $3.29

With a total of 3 10%'s taken off, or in this case, 30% off, we can conclude that the discounted prices of $3.29 is 30% of the original price.

Answer:

40% is the answer

Step-by-step explanation:

They are 7 ounces of combined meat and cheese in each sandwich (4+3 =7)

There were 13 sandwiches made in the hour (91 oz/7 oz = 13)

52 ounces of meat were used (4*13 = 52) If 13 sandwiches were made, and we know that 4 ounces of meat were used on each sandwich, 4*13 would tell us how many ounces of meat total were used.

39 ounces of cheese were used (3*13 = 39) If 13 sandwiches were made, and we know that 3 ounces of cheese were used on each sandwich, 3*13 would tell us how many ounces of cheese total were used.

You can check to see if the multiplication answers are correct by adding them (39+52 = 91)

I hope this helps you!

Answer:

The answer is (3, 1.25).

Step-by-step explanation:

Since A is at (1, 1.75), count over to B in a way you would count quarters. Don't worry about going down to it just count over to B to where you're over the point. The number that you get for counting over to B is the first number which is 3. Then go back to point A and count down like your counting quarters until you're right across from point B. The number that you get from counting down to B is the second number which is 1.25. Put them together and you get (3, 1.25).

Hope this helps.

Answer:

x^2 + 14x + 49

Step-by-step explanation:

The current expression is a binomial because it has two terms (x and a 7).

To make it a trinomial, we multiply x + 7 by itself (because it is getting squared in the expression).

(x + 7)^2 can be written as (x + 7)(x + 7).

To simplify that out, we use the method FOIL. Foil essentially means you multiply the FIRST two values in the parenthesis, and then the OUTSIDE values of the parenthesis and then the INSIDE values of the parenthesis, finally multiplying the LAST values in the parenthesis. This is how it looks:

(x * x) + (7 * x) + (7 * x) + (7 * 7).

Simplifying, we get x^2 + 14x + 49, which has three terms, thus making it a trinomial.

Hope this helps! :)
