B

6/4=18/X
6x= 72
X=12

Or you can say 4+4+4=12

GEF~CBF, because <F is general and <GEF=<CBF=90°. => GE:CB=EF:BF=6:18=1:3
GE:CB=1:3
4:CB=1:3
CB=12
The answer is B

78 is 15% of what #?

nirvana33 [79]

1. 78 = 0.15x
78 / 0.15 = x
520 = x.....so 78 is 15% of 520

2. | 3x - 2 | = 8 | x + 1 | = 1

3x - 2 = 8 -(3x - 2) = 8 x + 1 = 1 -(x + 1) = 1
3x = 8 + 2 -3x + 2 = 8 x = 1 - 1 -x - 1 = 1
3x = 10 -3x = 6 x = 0 -x = 2
x = 10/3 x = -2 x = -2

ur answer is : x = -2

3. 3y - 4x + 5 = 0
3y = 4x - 5
y = 4/3x - 5/3
slope = 4/3

A survey of a group’s viewing habits over the last year revealed the following information: (i) 28% watched gymnastics (ii) 29%

almond37 [142]

Answer: D) 52%

Step-by-step explanation:

G = gymnastics

B = baseball

S = soccer

G = 28%

BA = 29%

S = 19%

G and BA = 14%

BA and S = 12%

G and S = 10%

GBS = 8%

So, as we can see at the Venn diagram attached (consider every number in %)

GBS = 8

A = G and S - GBS = 10 - 8 = 2

B = G and BA - GBS = 14 - 8 = 6

C = BA and S - GBS = 12 - 8 = 4

Only G = G - A - B - GBS = 28 - 2 - 6 - 8 = 12

Only BA = BA - B - C - GBS = 29 - 6 - 4 - 8 = 11

Only S = S - A - C - GBS = 19 - 2 - 4 - 8 = 5

So, 2+6+4+12+11+5+8 = 48

100 - 48 = 52%
