6.4 - 2x - 6.63x = 610.5
subtract 6.4 from both sides
-2x -6.63x =604.1
collect like terms
-8.63x = 604.1
divide both sides by -8.63
x= -70
Population are always modeled by exponential growth equation given by:
f(x)=a(1+b)^t
where:
a=original number
b=rate of growth
t=time
thus
f(x)=412(1.05)^t
the population after 9 months will be:
f(9)=412(1.05)^9=639.15=639
Answer:
Step-by-step explanation:
This represents an arithmetic progression with the first term of a = 15 and common difference of d = 3.
<u>The tenth row is the 10th term:</u>
<u>The row 10 has:</u>
- a₁₀ = 15 + 9*3 = 15 + 27 = 42 seats
Answer:
40 cm
Step-by-step explanation:
10x4= 40
Translate
'what' means unknown or find this or ?
'is' means = or equals
22%
'of' means multiply
50
percent means parts out of 100
x%=x/100 so 22%=22/100
so
what is 22% of 50 means
?=22/100 times 50
?=1100/100
?=11
answer is 11
the hack, is to recognize that 50 is 1/2 of 100, so 22% of 1/2 of 100 is 22/2=11
answe ris 11
