D. 2(n-8)
The difference of a number and eight is separate from being multiplied by 2 which is why you would use parenthesis.
Answer:
c
Step-by-step explanation:
Since the figures are similar then the ratios of corresponding sides are equal, that is
= 
, substitute values
= 
( cross- multiply )
10YZ = 230 ( divide both sides by 10 )
YZ = 23 → c
<span> the population grows at rate of 1.75
multiply it by this rate every year
As in year 3 it would be 5340(1.75)(1.75)(1.75)
the function is 5340(1.75)^x
</span>f(x) = 5340(1.75)^x where 1.75 is the rate of growth
so D is right answer
Answer:
Fraction Percentage Decimal
¹/₅ 20% 0.2
¹/₄ 25% 0.25
¹/₂ 50% 0.5
²/₃ 66.6% 0.6
Fraction;
25/100 = 1/4
66.6/100 = 2/3
Percentage
1/5 * 100 = 20%
1/2 * 100 = 50%
Decimal
1/5 = 0.2
25/100 = 0.25
1/2 = 0.5
