Because there are 4 students who passed in all subjects, we can say that only 2 students passed in English and Mathematics only, only 3 students passed in Mathematics and Science only, and no one passed in English and Science only.

Given that we have deduced the number of students who passed in two subjects, we can now solve for the number of students who passed only one subject. 
                English = 15 - (4 + 2 + 0) = 9
                Mathematics = 12 - (4 + 3 + 2) = 3
                Science = 8 - (4 + 3 + 0) = 1

1. In English but not in Science,
                    9 + 2 = 11
2. In Mathematics and Science but not in English
                    3 + 3 + 1 = 7
3. In Mathematics only 
                             = 3
3. More than one subject only
                   3 + 4 + 2 + 9 = 18

It will really be helpful if you draw yourself a Venn Diagram for this item.

Answer:

there are 4 students who passed in all subjects, we can say that 2 students passed in English and Mathematics,  3 students passed in Mathematics and Science only, and no one passed in English and Science only.

Step-by-step explanation:

Given that we have deduced the number of students who passed in only two subjects, we can now solve for the number of students who passed only one subject. 

               English = 15 - (4 + 2 + 0) = 9

               Mathematics = 12 - (4 + 3 + 2) = 3

               Science = 8 - (4 + 3 + 0) = 1

1. In English but not in Science,

                   9 + 2 = 11

2. In Mathematics and Science but not in English

                   3 + 3 + 1 = 7

3. In Mathematics only 

                            = 3

3. More than one subject only

                  3 + 4 + 2 + 9 = 18

Help i give 5 stars and a crown​
REY [17]

Answer:

See below.

Step-by-step explanation:

1a)

<u>Angles:</u>

  • 48, 90, 90, a.

<u>Add:</u>

  • 48 + 90
  • = 138 + 90
  • = 228

<u>Subtract:</u>

  • 360 - 228
  • = 132.

Angle a: 132.

1b)

To get angle h above 180°, <u>We need to add h + 164:</u>

  • h + 164
  • = 110 + 164
  • = 274.

h = 110.

This is how to get h over 180°.

I’m stuck on this question please help
Komok [63]
Take the price of pears (£1.30 per kilogram) and multiply it by the amount of pears (7kg). You get 9.1 so now you take the total amount spent (£12.70) and subtract the 9.1 and you get 3.6 now that is the amount you spent on the apples. So take 3.6 and divide it by the amount of apples you got (2kg) you will get 1.8 and that is your overall answer.
