Answer:
12
Step-by-step explanation:
Given that
Current count of pushups = 8
Number of increase in pushups each day = 2
The desired pushup goal on daily basis = 30
Days require = x= ?
as we can conclude the number of pushups would increase by following sequence
8, 10, 12, 14, 16, ......30
Now as we can be the number of pushups by a constant number each day it means this sequence is arithmetic.
First term of our sequence is X1 and the final term is Xn, and the difference between two consecutive terms (Common Difference) is 2.
So
X1 = 8
Xn = 30
d = 2
Using the formula of nth term for arithmetic sequence
Xn = X1 + (n-1)d
Substituting the values
30 = 8 + (n-1)2
30-8 = (n-1)2
22 = 2n -2
22+2 = 2n
2n = 24
n = 24/2
n = 12
So, it means on the 12th day he will have to do 30 pushups if he starts from 8 and increase 2 pushups each day.
Answer:
25 + 2x= 325 x=150
Step-by-step explanation:
-25 -25
2x 300
/2 /2
×= 150
Hey user
the answer to this is going to be
2 c
hope this helped
have a good day
Please include the instructions when you post a question. Thanks.
Use the formula A = P*e^(rt).
Here, A = $700*e^(0.065*t), where t is the # of years (which you have not yet included in your post).
As an example: After 2 years you'll have A = $700*e^(0.065*2), or A=$797.18, in your account.
Answer:
$51.75
Step-by-step explanation:
Okay, so. They decreased there interest by .15. It is really nothing. So, we have no clue how many years. So, we will just use one year. We would start by multiplying 50 and 3.5% that will equal 1.75. Then we would add it up. 50 + 1.75, it will equal to 51.75.
Therefore your answer is $51.75
Hope this helps!
