Hannah has an eraser 1 1/2 in. long, a pencil 5 7/8 in. long, and a marker 7 5/8 in. long. Can she arrange these items into a triangle? Explain your thinking.

Answer: 24 over 2 squared equals 50 minus 6 squared minus 8

56 divided by 8 plus 3 squared equals 2 times 2 cubed

Step-by-step explanation:

24/2^2 = 50-6^2 - 8

24/4 = 50-36-8

6 = 14-8

6=6

39-3*6 = 6*10/4 + 4

39 - 18 = 15 + 4

21 = 19

9^2 - 5 ^ 2 = 4 ^ 2 - 7

81 - 25 = 16 - 7

56 = 9

56/8 + 3^2 = 2 * 2^3

7 + 9 = 2 * 8

16 = 16

Answer:

 A newspaper is organized in a logical format. The front page has the most exciting news of the day. The editors determine what is most newsworthy for their readership. The A-section contains world and national news; the B-section contains local news. Some of the categories include entertainment, local news, national news, classified advertisement, and neighborhood news. They are laid out the way they are because they want to catch the reader's eyes. They want the reader to look at the newspaper and think "oh that looks interesting."

Answer:

124/67 and 1/3

Step-by-step explanation:

The second ratio is 1.5/4.5, which readily reduces to 1/3.

Dividing both numerator and denominator of 24.8 / 13.4 by 2 yields the simpler 12.4 / 6.7  or  124/67.  This latter result cannot be reduced.

Answer:

Option D.

Step-by-step explanation:

Let the coordinates of a point which divides the segment XY in the ratio of m : n is (x, y).

Segment X(-4, -9) and Y(4, 7) has been divided in the ratio of 2 : 6.

Therefore, x = \(\frac{[4m+n(-4)]}{m+n}=\frac{8-24}{2+6}\)

                    = -\(\frac{16}{8}\)

                    = -2

and y = \(\frac{[7m+n(-9)]}{m+n}=\frac{14-54}{2+6}\)

         = \(-\frac{40}{8}\)

         = -5

Therefore, the point (x, y) is (-2, -5).

Option D. will be the answer.

Answer: 7/15

Step-by-step explanation:

2/3 - 1/5

Find the LEAST COMMON DENOMINATOR for 3 and 5. (These are the bottom numbers of your fractions!)

The least common denominator for 3 and 5 is 15.

Look at it this way.

Multiply 3 by 1, 2, 3, 4, 5:

3, 6, 9, 12, 15

Multiply 5 by 1, 2, 3:

5, 10, 15

Both of them match at 15! This is your least common denominator.

Now, let's go back.

2/3 - 1/5

Since you want 15 on the bottom, multiply 2/3 by 5/5.

2 x 5 = 10

3 x 5 = 15

Now we have: 10/15

We also want 15 on the bottom of 1/5. Multiply by 3/3.

1 x 3 = 3

5 x 3 = 15

Now we have: 3/15

Finally, you can solve the problem!

10/15 - 3/15 = ?

Your answer is: 7/15.

Answer:

Step-by-step explanation:

To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.

Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.

The sum of the parts in the ratio is 8x + 5x + 2x = 15x.

We know that the total number of fruits is 120. Therefore, we can set up the following equation:

15x = 120

To solve for x, we divide both sides of the equation by 15:

x = 120 / 15

x = 8

Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:

Number of bananas = 2x = 2 * 8 = 16

So, there are 16 bananas in total.

We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.

Answer:

(9, -15)

Step-by-step explanation:

First, label the 2 equations:

-10x -6y= 0 -----(1)

-4x -6y= 54 -----(2)

(2) -(1):

(-4x -6y) -(-10x-6y)= 54 -0

-4x -6y -(-10x) -(-6y)= 54 (expand, simplify)

-4x -6y +10x +6y= 54 (expand)

10x -4x= 54 (simplify)

6x= 54

x=54 ÷6

x= 9

susbt. x=9 into (1):

-10(9) -6y=0 (subst. x=9 into -10x-6y=0)

-90= 6y (bring y term to the other side)

6y= -90

y= -90 ÷6

y= -15

Thus, the solution is (9, -15).

The value of X is 9.

The value of y is -15.

Answer:

Q1)$-95.75

Q2)$140.20

Q3)D

Q4)D

Answer:

Q1- total amount of negative balances: -95.75

Q2- Total amount of positive balances: 140.2

Q3- D:129.86

Q4- D: 37.84

Step-by-step explanation:

Q1- Add up all the negative numbers: (-19.00)+(-30.25)+(-46.50). this turns into: -19.00-30.25-46.50= -95.75

Q2- Add up all the positive numbers: 56.84+83.36= 140.20

Q3- use one of the numbers that were given to you and subtract account E from it and you should get the amount in account C. In this case we use $129.86.

So 129.86-46.50= 83.36

Q4- Add up both accounts. Account B is a negative amount and account A is a positive amount, we do -B+A

-19.00+56.84= 37.84

Answer:

Mean = 33.7

Median = 34.5

Mode = 34

Range = 33

After adding 26....

mean decreases by 0.7

median decreases by 0.5

mode is 34

range is 33

Step-by-step explanation:

mean = sum of all the data values/number of data values

= (18 + 19 + 20  + 34 + 34 + 35 + 37 + 42 + 47 + 51)/10
= 337/10
= 33.7

To find median arrange the values in increasing order, find the mid value

If the number of data points is even, find the average of the mid 2 data values

Arranging data values we get:
18, 19, 20, 34, 34, 35, 37, 42, 47, 51

Since there are 10 data values, take the average of the middle two:
(34 + 35)/2 = 34.5

The mode is the value that occurs most often. We see that there are two instances of 34 whereas the other values appear only once

Mode = 34

The range is highest - lowest = 51 - 18 = 33

After we add 26, we get the following data set arranged

18, 19, 20, 26, 34, 34, 35, 37, 42, 47, 51

we can calculate the stats using the same technique as above

We get the following values

mean = )(18 + 19 + 20 + 26 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/11
= 33  

median = 34

mode = 34

range = 51-18 = 33

To find the decrease in mean and median subtract from the first set of values

Answer: yes, because it is useful to describe changes in the behavior of the thing we are describing.

Step-by-step explanation:

A piecewise function f(x) is a function that is "different" depending on the range of the values of x, this is for example:

y = x -----> if x < 0

y = x^2 ----- if x ≥ 0

This is used to represent changes in the behavior of the thing we are describing.

For example, suppose an object that is moving with constant velocity, the velocity graph will be a constant line.

Now, the object suddenly, at a time t = t0 accelerates to a constant acceleration A, now the graph of the velocity is a linear graph with slope equal to A.

So this situation can be represent this with a piecewise function:

V(t) = c -----> if t < t0

V(t) = c + A*t -----> if t ≥ t0

So the answer is yes, we can.

Answer:

14) AED = 139

15) CEF = 90

16) DEB = 41

17) BEF = 49

18) CEB = 139

19) AEF = 131

Step-by-step explanation:

14) DEC = 180 degrees, because it is a straight line. We know that AEC is 41 degrees, so to find AED, we just subtract DEC (180) by AEC (41) which is 139.

15) CED = 180 degrees, because it is a straight line. We know that DEF is 90 degrees, because it is a right angle, so to find CEF, we just subtract CED (180) by DEF (90) which is 90.

16) AEC = 41 degrees and we know that AEB and CED are straight lines, so that means it will be the same measurement on the other side, so DEB = 41.

17) We know that DEF is 90 degrees, because it is a right angle, and that DEB is 41 degrees, so to find BEF, we just subtract DEF (90) by DEB (41) which is 49.

18) We know that CEF is 90 degrees, because it is a right angle, and that FEB is 49 degrees, so to find CEB, we just add CEF (90) to FEB (49) which is 139.

19) We know that CEF is 90 degrees, because it is a right angle, and that AEC is 41 degrees, so to find AEF, we just add CEF (90) to AEC (41) which is 131.
