Sharon is building bookshelves for her room.She bought a board that is 10 1/2 feet long.If she cuts the board in three equal pieces, how long will each shelf be?

Answers

Each shelf would be 3 1/2 inches
Hey there!

To solve this you divide 10 1/2 by 3:

10 1/2 = 21/2
3 = 3/1

21 x 1 = 21
2 x 3 = 6

21/6 is the answer, but when we simplify it we get 3 1/2 as our final answer.

Each shelf will be 3 1/2 feet long.

Hope this helps you.

Use the Pythagorean theorem to determine the distance between point A(-8,8) and point B(-5,1), the distance between point C(2,7) and point D(8,-5), and the distance between point E(3,-7) and point F(-6,-9).

The distance between points__and __is the greatest. The distance is___units.

Answers

Final answer:

The Pythagorean theorem is used to find the distance between points in a coordinate plane by calculating the hypotenuse of a right triangle formed by the coordinates. The greatest distance is between point B and point E.

Explanation:

To find the distance between two points using the Pythagorean theorem, you need to know the coordinates of the points. The formula for the distance between two points (x1, y1) and (x2, y2) is:

distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)

For point A(-8,8) and point B(-5,1):For point C(2,7) and point D(8,-5):For point E(3,-7) and point F(-6,-9):

The greatest distance is between point B and point E, which is approximately __units long.

What is percentage?

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

Given, Eight students share 12 mini oatmeal muffins equally and 6 students share 15 mini apple muffins equally.

In first group,

Each student will get = 12/8

Each student will get = 3/2 mini muffin

In second group,

each student will get = 15/6

each student will get = 5/2

Since, carmine is in both the groups,

She will get = 5/2 + 3/2

Carmine will get total mini muffin = 8/2 = 4

Therefore, Carmine will have 4 muffins for herself.

To find the measure of angle 2 in the given triangle, subtract 180 degrees from the sum of the other two angles.

Explanation:

To find the measure of angle 2 in the given triangle, we need to use the fact that the sum of angles in a triangle is always 180 degrees.

Thus, Angle 3 can be found by subtracting angles 1 and 2 from 180 degrees: Angle 3 = 180 - 42 = 138 degrees.

Finally, Angle 2 can be found by subtracting Angle 3 and Angle 4 from 180 degrees: Angle 2 = 180 - 138 - 81 = 39 degrees.

Write in slope-intercept form an equation of the line that passes through the given points. (−9, 5), (−3, 3)

Answers

The slope intercept form is the y = mx + b
We need to solve for the slope first
remember
the slope is the change in y/ over the change in x
y2 - y1 / x2 - x1
3 - 5 / -3 --9
-2/6 this can be simplified to -1/3
That is the slope so we plug it into the equation
y = mx + b
m = slope
y = -1/3x + b
Now to solve for the y-intercept, we plug in one of the coordinates to solve for b
3 = -1/3(-3) + b
3 = 1 + b
3 = b + 1
subtract 1 from both sides
2 = b
That is the point where it intercepts the y-axis
(0,2)

Now we have our equation for the line that passes through the points, (-9,5)(-3,3). 
That equation is y = -1/3x + 2

Hope this helps :)

The slope intercept format is y = -1 / 3x + 2

The slope intercept formula is represented as follows

y = mx + b

where

m = slope

b = y-intercept

Therefore, let's find m using the coordinates (-9, 5)(-3, 3)

m = 3 - 5 / -3 - (- 9)  = -2 / 6 = - 1 / 3

let's find b using the coordinate(-3, 3)

3 = -1 / 3 (-3) + b

3 = 1 + b

b = 2

Finally,

y = -1 / 3x + 2

18.65 × 6.8 how do you do it

Answers

18.65
 *  6.8
_____
         126.82
First, multiply the numbers and ignore the decimal points. Just pretend the decimal points are not there.

        18.65
     x     6.8
    -----------
       14920
   + 11190
  ------------
     126820

Now you need to place the decimal point.
The original numbers are 18.65 and  6.8.
18.65 has 2 decimal places to the right of the decimal point.
6.8 has 1 decimal place to the right of the decimal point.
Add the number of decimal places to the right of the decimal point of both numbers: 2 + 1 = 3.
The answer, 126820, must also have 3 decimal places to the right of the decimal point, so we count digits starting at the right side (with the 0, and we place the decimal point after the third digit (to the left of the third digit).
126.820
Since a final zero after the decimal point has no value, we simply write 126.82

Answer: 126.82

Rule: the "larger" the number numerically in the minus region, the smaller the number actually is. Think money. Which would you rather be - 1000 dollars or - 100 dollars. Well you may say neither, but you have to choose. I would rather be just 100 dollars in debt which is - 100 from my point of view.

There are 7 cards with a picture of a rose and 2 cards with a picture of a daisy. Alfa keeps all the cards face down on the table with the pictures hidden and mixes them up. She then turns over one card face up and finds the picture of a rose on it. She removes this card from the table and turns over another card without looking. What is the probability that the card that Alfa turns over has a rose on it? 6 over 9 6 over 8 7 over 9 7 over 8

Answers

The answer would be 6/8 because she has already taken out one of the rose cards, so now you're only left with 8 cards. There are still 2 daisy cards, so you would subtract 8 by 2 and get 6. This makes it 6/8.

Answer: [tex]\dfrac{6}{8}[/tex] or 6 over 8.

Step-by-step explanation:

Given: The number of card having rose on it  = 7

The number of card having daisy on it = 2

Then the total number of cards on table = [tex]7+2=9[/tex]

After removing one rose card , the total number of cards left on table = 8

The number of rose card left on table = 6

Now, the required probability is given by :-

[tex]\text{P(Rose)}=\dfrac{\text{Number of rose card }}{\text{Total cards}}\\\\\Rightarrow\text{P(Rose)}=\dfrac{6}{8}[/tex]

Hence, the probability that the card that Alfa turns over has a rose on it = [tex]\dfrac{6}{8}[/tex]

A 14-ounce box of cereal sells for $2.10. what is the unit rate.

Answers

Final answer:

To find the unit rate for a 14-ounce box of cereal selling for $2.10, divide the price by the number of ounces to get $0.15 per ounce.

Explanation:

The unit rate for a 14-ounce box of cereal selling for $2.10 can be calculated by dividing the price of the box by the number of ounces it contains. To find the unit rate, you would perform the following calculation:

Unit rate = Price per box ÷ ounces per box

Unit rate = $2.10 ÷ 14 ounces

Unit rate = $0.15 per ounce

Therefore, the unit rate or cost per ounce for the cereal is $0.15.

-4x-2(8x+1)=-(-2x-10)

Answers

-4x - 2(8x + 1) = -(-2x - 10)

The first step is to distribute. On the left side of the equation, multiply the -2 by both terms inside the parentheses; on the right side of the equation, multiply the -1 by both terms inside the parentheses:

-4x - 2(8x + 1) = -(-2x - 10)
-4x - 16x - 2 = 2x + 10

Next, combine like terms.

-4x - 16x - 2 = 2x + 10
-20x - 2 = 2x + 10

Then subtract 2x from both sides and add 2 to both sides to get like terms together; combine like terms.

-20x - 2 = 2x + 10
-20x - 2x = 2 + 10
-22x = 12

Lastly, divide both sides by -22 and simplify.

-22x = 12
x = 12/-22
x = -6/11

Answer:
