Answer:
Brownies
18
54
270
Cooldies
16
32
96
384
Step-by-step explanation:
Brownies
simply multiply the 18 by 3 we get 54 and if we multiply 54 by 5 we get 270.
we multiply it by 5 because in series it skip 1 number to multiply next.
Cooldies
first we multiply 16 by 2 we get 32.
next we multiply 32 by 3 we get 96.
and next we multiply 96 by 4 we get 384.
Simply increment in multiplication.
A is located at (-3,-5) B is located at (1,-9)
-3 + 1 = -2/2 =-1
-5 + -9 = -14/2 = -7
midpoint is (-1,-7)
Answer: 644,800
Step-by-step explanation:
This can also be solved using the terms of Arithmetic Progressions.
Let the 13 years be number of terms of the sequences (n)
Therefore ;
T₁₃ = a + ( n - 1 )d , where a = 310,000 and d = 9% of 310,000
9% of 310,000 = 9/100 x 310,000
= 27,900
so the common difference (d)
d = 27,900
Now substitute for the values in the formula above and calculate
T₁₃ = 310,000 + ( 13 - 1 ) x 27,900
= 310,000 + 12 x 27,900
= 310,000 + 334,800
= 644,800.
The population after 13 years = 644,800.
Answer:
<h3>39.6</h3>
Step-by-step explanation:
collecting like terms we have:
5x-2x=-1+42
equating the terms..we have:
3x=41
divide both sides by the Co-efficient of x:
3x\3=42\3
x=39.6
