Answer:
140 ounces of water and 105 ounces of 35% salt solution.
Explanation:
Let
be the ounces of water that need to be added and
be the ounces of 35% solution that need to to be added.
We know that the total of ounces of water and of 35% solution must be 245 ounces:

35% of
is the salt, and since no salt is added with addition of
liters of water, this must be equal to the amount of salt in the final 15% solution:

we solve for
and get:

We put this value into
and solve for
to get:

Thus we have 140 ounces of water and 105 ounces of 35% solution.
<span>The correct answer to the question "Forms of money in the United States consist of paper money, coins, and _____." is checking account balances.
Money is any item or verifiable record that is generally accepted as payment for goods and services and repayment of debts in a particular country or socio-economic context, or is easily converted to such a form.
The money supply of a country consists of currency (banknotes and coins) and bank money (the balances held in checking accounts, savings accounts, and other types of bank accounts).</span>
In order to solve first convert both values into improper fractions:
18/5+63/10
second, convert both values to fractions with a base of ten:
36/10+63/10
finally, add the numerators:
99/10 is the final answer
1) This is not an arithmetic sequence because it has n².
2) To find 5 first terms of this sequence, you can simply substitute n with 1,2,3,4, and 5, and calculate values of a(1),a(2), a(3), a(4) and a(5).
a(n) = 3n²- 1
n=1 a=3*1² - 1 = 3-1=2
n=2 a=3*2² - 1 = 11
n=3 a=3*3² - 1 =26
n=4 a=3*4² - 1 = 47
n=5 a=3*5² -1 = 74

Answer C. 2,11,26,47,74.
Answer:
653.45 cm^2
Step-by-step explanation:
The volume of a cylinder can be found using:
v=pi r^2 h
We know the radius is 4, and the height is 13, so we can substitute them in
v=pi (4^2)(13)
v=pi (16)(13)
v=pi 208
v=653.451272
Rounded to the nearest hundredth
v=653.45
So the volume is 653.45 cm^3
