Answer 1

Answer:

Answer:

$\boxed{2144}$

Step-by-step explanation:

The sum can be found by adding the parts:

$\sum\limits_(n=1)^(32){(4n+1)}=4\sum\limits_(n=1)^(32){n}+\sum\limits_(n=1)^(32){1}=4\cdot(32\cdot 33)/(2)+32\n\n= 2112+32=\boxed{2144}$

The sum of numbers 1 to n is n(n+1)/2.

What is the value of 2.57 1.75

Answers

Answer:

2.57 - 1.75 = 0.82

Step-by-step explanation:

Let us assume that we need to find the value of 2.57 - 1.75 i.e. we need to subtract 1.75 from 2.57. It can be done as follows :

The first number is 2.57 and other no is 1.75.

In 2.57, 2 is in ones place, 5 is in tenths place and 7 is in hundredths place.

In 1.75, 1 is in ones place, 7 is in tenths place and 5 is in hundredths place.

Subraction :

2.57

- 1.75

= 0.82

Hence, the value of 2.57 - 1.75 is 0.82

In January 2010, Diana invested $4,500 in an account that paid interest compounded annually. the table showstopper balance of the account at different times. what was Diana's balance, in dollars and cents, in January 2014. the numbers on the table are, For the month Jan. 2011-$4,635.00Jan. 2012-$4,774.05
Jan. 2013-$4,917.27

Answers

Final answer:

The question is related to compound interest. Diana's account balance in 2014 cannot be precisely calculated with the provided information, but based on the increasing balance trend, it would be larger than the 2013 balance of $4,917.27.

Explanation:

The subject of this question is compound interest, which is used in Mathematics. When Diana invested $4,500 in an account in 2010, the balance in the account increased each year due to the interest being compounded, or added to the principal amount. For example, by January 2011, the balance had grown to $4,635.00. The balance continued to grow each subsequent year.

To find Diana's balance in 2014, we would typically need to apply the formula for compound interest. However, in this case, the question only provides the balances for the years up to 2013. If a similar growth pattern continued, we could expect that the balance in 2014 would be larger than the $4,917.27 balance of 2013. Without a specific interest rate or an exact balance for 2014, we cannot precisely calculate the 2014 balance.

The amount of carbon 14 still present is a sample after t yearsis given by the function C(t)=
Coe-.00012t
where co is the initial anong . estimate the age of a sample of
wood discoverd by a arecheologist if the carbon level in the sample
is only 20% of it orginal carbon 14 level.

Answers

Answer:

The age of this sample is 13,417 years.

Step-by-step explanation:

The amount of carbon 14 present in a sample after t years is given by the following equation:

$C(t) = C_(0)e^(-0.00012t)$

Estimate the age of a sample of wood discoverd by a arecheologist if the carbon level in the sampleis only 20% of it orginal carbon 14 level.

The problem asks us to find the value of t when

$C(t) = 0.2C_(0)$

So:

$C(t) = C_(0)e^(-0.00012t)$

$0.2C_(0) = C_(0)e^(-0.00012t)$

$e^(-0.00012t) = (0.2C_(0))/(C_(0))$

$e^(-0.00012t) = 0.2$

$ln e^(-0.00012t) = ln 0.2$

$-0.00012t = -1.61$

$0.00012t = 1.61$

$t = (1.61)/(0.00012)$

$t = 13,416.7$

The age of this sample is 13,417 years.

8 pencils and one eraser cost $1.35 and 6 pencils and one eraser cost $1.05. How much does one pencil cost?

Answers

Answer:

one pencil cost $0.15

Step-by-step explanation:

Answer: $0.15 and/or 15 cents

Explanation: If you use common sense, information provided, and basic math, you notice that after 2 pencils were removed the total cost dropped 30 cents/$0.30; therefore, after 2 pencils are taken away the cost drops 30 cents and to find the price for one pencil all you have to do is divide 30/2 and you get 15 cents and/or $0.15.
