We can name an angle either by naming its vertex or by three letters , keeping the letter of vertex in between.

so here vertex is F

we can name it as ∠EFG, ∠F , ∠GFE

This strikes out the option B that is ∠G

so option B is the answer

Answer:

The weight of large box = 13.75 kilograms

the weight of small box = 6.5 kilograms

Step-by-step explanation:

Given:

delivery of 2 large boxes and 3 small boxes has a total weight of 47 kilograms

delivery of 6 large boxes and 5 small boxes has a total weight of 115 kilograms.

Let x be the weight of large box

and y be the weight of small box

Make equation from the given information

2(weight of large box) + 3(weight of small box) = 47

2x + 3y = 47 -----------> equation 1

Do the same and make one more equation

6x + 5y = 115-----------> equation 2

Now we solve both equation using elimination method

Multiply the first equation by 3

6x + 9y = 141

6x + 5y = 115 (subtract both equations)

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

4y = 26

divide both sides by 4

So y= 6.5

Now plug in 6.5 for y and find out x

2x+3y = 47

2x + 3(6.5) = 47

2x + 19.5 = 47 (subtract 19.5 on both sides)

2x = 27.5

divide both sides by 2

x = 13.75

The weight of large box = 13.75 kilograms

the weight of small box = 6.5 kilograms

20% of the girls in class have blonde hair. 16 girls do not have blonde hair. How many total students

yawa3891 [41]

The problem is to find how many students have either blond hair or glasses and then divide that by the total number of students; that will find the probability.
Since 7 have blonde hair and 9 have glasses, that would be a total of 16 persons if there were no overlap; that is, no blonde wears glasses and nobody who wears glasses is a blonde.
But there are 4 persons who have both blond hair and wears glasses. That means, of the 7 who are blondes, 3 of them do not wear glasses. And, of the 9 who wear glasses, 5 of them are not blondes.
So we have 3 who are blondes without glasses, 5 who wear glasses who are not blondes, and 4 blonds with glasses, for a total of 12 persons.
The probability is, therefore, 12/26 or 6/13.
