21 is to 75 as 7 is to 25 . We can now change 25 to 100 by multiplying by 4 . Therefore , on also multiplying 7 by 4: 21 is 28% of 75
Answer: d = 6
Step-by-step explanation:
x^2 + y^2 = r^2
So r = 3 and d will be 2 x r = 6
Answer:
Solve for X ( The question I did was an example )
Step-by-step explanation:
To solve and equation like 2x+9=30 you will have to isolate the number with a variable. You need to subtract 9 on both sides for that to happen.
2x=21
Now the next step is to divide. You have to divide to get the answer.
x=21/2
x= 10.5
Answer:
it seems like the first term is -64, so lets write the formula accordingly:
a_n = a1(r)^(n-1)
where 'n' is the number of terms
a1 is the first term of the sequence
'r' is the ratio
the ratio is because -64 * = 16 and so on...
the explicit formula is :
=
The answer is D becoz of the explanations
