Answer:
12,500-11,625=875
875/12,500=7/100
7/100*100=7
The percentage reduction is 7%
P.S * represents multiplication
Answer:
84
Step-by-step explanation:
x = number of girls
The total for boys is 2x * 81 and for girls it would be 90x
Therefore, the equation goes like this:
2x * 81 + 90x
Then simplify, and set to equal 3x...
3x = 252
Which is the same as
x = 84
Thank me later :)
Its about 13.64% multiply 4.75 by 100 then divide by 5.5 then subtract that number from 100
Answer:
4. 8.0
5. 27.6
6. 35.5 degrees
Step-by-step explanation:
#4- Cos 48= x/12
0.669131= x/12
x=8.0
#5
Sin 78= 27/x
0.978=27/x
0.978x=27
x=27.6
#5
Tan X= 15/21
tan x= .714
inverse tan= 35.5 degrees
Answer:
Step-by-step explanation:
abs ( -2(5-(-1)) / 3 )
= abs ( -2(5+1) / 3 )
= abs ( -2(6) /3)
= abs (-12 /3)
= 4
(3(-1) -- 1) /2
= (-3 -1) /2
= -4 / 2
= -2
since 4 is greater than - 2 this is inequality is true
