A pear weighs 7/8 pound. A case contains 12 pears. If each pear weighs the same, how much does the case of pears weigh?

Answer: D (Mean is 85)

Explanation:

"The list below shows the quiz scores for a group of students.

95, 80, 80, 85, 80, 85, 90"

The choices talk about median and mode so we find those first:

Median: find by taking which is the middle number when the data is from low to highest

1) rearrange them from low to high

80, 80, 80, 85, 85, 90, 95

2) find middle number

80, 80, 80, 85, 85, 90, 95

The median is 85

Mean: mean is the average of all numbers. Find by adding numbers and dividing by amount of numbers

1) add 80, 80, 80, 85, 85, 90, 95 and get 595

2) There are 7 total numbers so do 595/7 = 85

The mean is 85

why?

A is wrong because they are 85 not 80

B is wrong because it is 85 not 80

C is wrong because it is 85 not 80

D is right because it is 85!

Answer:

673.6? ur supposed to divide right?

Answer:

No 4 is easy you get 2/3

My explanation is just make the denominator the same which is 13/6 - 9/7

13 x 7/6x7 - 9x6/7x6

The answer it its 91/42 - 63/42

=28/42

If you simply it it would be 2/3

(/ this means by) sorry for my bad explanations

Answer:

We could calculate the range and median.

Answer:

1.  145-(3squared times 4)=109

2. 45 divided by 9 times 12-8= 52

3.  2 squared +3 times 4-12= 4

4.[155-(3 times 9) times 2] -12= 89

5. [(6 times 2) +(5 times 5)  times 3= 111

6. 2 times {15+[24-(1.5 times 2)]}= 72

Step-by-step explanation:

(BOMDAS) brackets, operations, multiplication, division, addition, subtraction

1. (deal with the brackets first)

3 squared=9 then times by 4 =9*4=36

so..

145-36=109

2. (start with division )

45 divided by 9 =5

so

5 times 12-8= 52

3. 2 squared = 4

4 times 3 =12

so

4+12-12 =4

4.  (deal with brackets first)

3 times 9 = 27

27 times 2=  54

155-54= 101

101-12=89

5. (deal with the brackets first)

6 times 2 =12    

5 times 5=25

so 12+25=  37 times 3 = 111

6.  (deal with the brackets first)

1.5 times 2= 3

24-3= 21

15+21=36

2 times 36= 72

hope this helps!!!

Answer:

No, It is not true

Step-by-step explanation:

First of all, we should have a number in the tenths place, and we don't.

Also, in the hundredths place, we should have 9, not 4.

And finally, the answers should be 0.195, not 0.042.

Answer:

This is False

You want to add it up as if there wasnt any decimal  than you want to put the decimals back 3 spots

0.025 + 0.17= 0.195

Answer:

area of triangular logo = ½ × base × height

= ½ × 8 × 11

2

= 22 in²

Answer:

22

Step-by-step explanation:

If you multiply the base times height, which would be 8 * 5 1/2, You get 44. Then multiply that by 1/2 to get the area, and you get 22.

Answer:

x = 3

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

120° is an exterior angle of the triangle , then

15x + 5 + 22x + 4 = 120

37x + 9 = 120 ( subtract 9 from both sides )

37x = 111 ( divide both sides by 37 )

x = 3

Answer:

Shaded area is 55 units²

Step-by-step explanation:

Ignoring the white cutout, we have a rectangle of length 10 and width 7 (count the squares in each direction).  The area of this larger rectangle is

(10 units)(7 units) = 70 units².  The white area that we previously ignored has dimensions 3 by 5 units, and thus an area of 15 units²  

Subtract the latter from the former, obtaining the net area

70 units² - 15 units² = 55 units²

Answer:

20 minutes( 0.3333 hours) after they leave the station will they be 50 km apart, if the Two trains on opposite tracks leave the same station at the same time. One train travels at an average speed of 80 km/hr and the other travels at an average speed of 70 km/hr.

Step-by-step explanation:

The given is,

                  One train travels at an average speed of 80 km/hr

                  The other travels at an average speed of 70 km/hr

Step:1

     Formula to calculate the distance traveled by two trains,

     Distance traveled by two trains = (Rate of speed of train one +

                                                          Rate of speed of other train) × Time

        From the given the above equation becomes,

        Let, h = Time taken to each the distance

                                         50 = ( 80 + 70 ) h

                                           50 = (150) h

                                                 = 0.3333 hours

                                                 = ( 0.333 × 60 )          ( ∵ 1 hr = 60 minutes )

                                               h = 20 minutes

Step:2

           Check for solution,

           From equation (1),

                          50 = ( 80+70 ) (0.3333)

                          50 = (150)(0.3333)

                          50 = 50

Result:

         20 minutes( 0.3333 hours) after they leave the station will they be 50 km apart.

Answer:

Step-by-step explanation:

The solution of a system of linear equations is the point of intersection of their graphs because the intersection represents the only x or y values that will satisfy both/all equations. The graph visually shows that the intersection of these equations is the only spot on the graph that all of the equations have in common. This means that only this spot will satisfy all equations. For example, the intersection may be (0,1); this means that for all equations an x value of 0 will always result in the y value of 1. However, an x or y value that satisfies one equation may not satisfy the others if they do not lead to the desired outcome.
