Lucy earned $400 and $550 in interest the last 2 years. Describe the average interest she should earn in each of the next 3 year
Rzqust [24]
So she has 400 and 500 so far.

now if she were to have an average of 2300 for the next 5 years, that means some years she made more, some she made less, but in the 5 years run, she made 2300 * 5 or 11500 total.

Neverminding the lows and highs, if we bundle up the 11500 bucks and divide by 5, that'd 2300, which is what's called the average, the average amount doesn't take into account that some numbers are higher than others, it kinda just flattens them out.

so in total she would have made 11500 in each account.

so in the account with 400, she needs 11100 more, how much will it be 1100 for the next three years on average?  11100/3  or 3700.

so if she earns 3700 each year, for the next 3 years in the account with 400 already, she'd have 11500 bucks in 5 years with an average of 2300.

now let's look at the 500 account, she needs 11000 more, how much will it be for 11000 for the next three years on average?  11000/3 or about 3666.67.

so if she earns 3666.67 each year, for the next 3 years, she'd have 11500 bucks in 5 yeas with an average of 2300.

Find an equation for the nth term of the arithmetic sequence.
amm1812

Answer:

a_n=-301 +37(n-1)

Step-by-step explanation:

arithmetic sequence formula:  a_n=a +(n-1)d

where a is the first term and d is the common difference

Given:

  a_{10}=32

⇒ a +(10-1)d=32

⇒ a+9d=32

Given:

    a_{12}=106

⇒ a +(12-1)d=106

⇒ a+11d=106

Rearrange the first equation to make a the subject:

a = 32 - 9d

Now substitute into the second equation and solve for d

    (32 - 9d) + 11d = 106

⇒ 32 + 2d = 106

⇒ 2d = 106 - 32 = 74

⇒ d = 74 ÷ 2 = 37

Substitute found value of d into the first equation and solve for a:

a + (9 x 37) = 32

a + 333 = 32

a = 32 - 333 = -301

Therefore, the equation is: a_n=-301 +37(n-1)

How do I find the percentage of 18/20
borishaifa [10]
Or for this and any other problem . every percentage is out of a 100

soooo ,
20 | 100 %
10 | 50 %
5 | 25 %
1 | 5 %

SOOO

10 + 5 = 15 50 % + 25 % = 75 % , so know we know 15/20 is 75 percent

but you need 18/20 not 15/20 , so 1 equals 5 % in this problem


1+1+1 = 3 5+5+5 = 15

15 + 3 = 90 75 + 15 = 90 , 18/20 = 90%

I know its probably alot but I wanted to show you all I did , so that it could maybe help you in the future , just gotta plug in different numbers
