Answer
Find out the total amount of interest earned at the end of 3 years .
To prove
Formula
![Simple\ interest = \frac{Principle\times rate\times time}{100}](https://tex.z-dn.net/?f=Simple%5C%20interest%20%3D%20%5Cfrac%7BPrinciple%5Ctimes%20rate%5Ctimes%20time%7D%7B100%7D)
As given
Dawnie deposited $350 In a savings account earns 3% simple interest over three years .
Here Principle = $350
Interest = 3%
Time = 3 years
Put in the above formula
![Simple\ interest = \frac{350\times 3\times 3}{100}](https://tex.z-dn.net/?f=Simple%5C%20interest%20%3D%20%5Cfrac%7B350%5Ctimes%203%5Ctimes%203%7D%7B100%7D)
![Simple\ interest = \frac{3150}{100}](https://tex.z-dn.net/?f=Simple%5C%20interest%20%3D%20%5Cfrac%7B3150%7D%7B100%7D)
Simple interest = $31.5
Therefore $31.5 is the total amount of the interest in 3 years.
Answer:
717,051
seven hundred seventeen thousand, fifty-one
Step-by-step explanation:
Answer: There are 34.35 liters left in the test tube.
Step-by-step explanation:
Since we have given that
Depth of the tube = 9 inches
Circumference of base=4 inches
As we know the formula of circumference ,
![Circumference=2\pi r\\\\4=2\times \frac{22}{7}\times r\\\\4\times{7}{22\times 2}=r\\\\\frac{7}{11}=r](https://tex.z-dn.net/?f=Circumference%3D2%5Cpi%20r%5C%5C%5C%5C4%3D2%5Ctimes%20%5Cfrac%7B22%7D%7B7%7D%5Ctimes%20r%5C%5C%5C%5C4%5Ctimes%7B7%7D%7B22%5Ctimes%202%7D%3Dr%5C%5C%5C%5C%5Cfrac%7B7%7D%7B11%7D%3Dr)
Now, we need to find the volume of tube is given by
![\text{ Volume of test tube }=\pi r^2h\\\\\text{ Volume of test tube }=\frac{22}{7}\times \frac{7}{11}\times \frac{7}{11}\times 9\\\\\text{ Volume of test tube }=\frac{126}{11}=11.45\ inches^3](https://tex.z-dn.net/?f=%5Ctext%7B%20Volume%20of%20test%20tube%20%7D%3D%5Cpi%20r%5E2h%5C%5C%5C%5C%5Ctext%7B%20Volume%20of%20test%20tube%20%7D%3D%5Cfrac%7B22%7D%7B7%7D%5Ctimes%20%5Cfrac%7B7%7D%7B11%7D%5Ctimes%20%5Cfrac%7B7%7D%7B11%7D%5Ctimes%209%5C%5C%5C%5C%5Ctext%7B%20Volume%20of%20test%20tube%20%7D%3D%5Cfrac%7B126%7D%7B11%7D%3D11.45%5C%20inches%5E3)
Since we have also given that,
Of 1 cubic inch of space holds 3 liters of water,
So,
![1\text{ cubic inch}=3\text{ liters}\\\\11.45\text{ cubic inches}=3\times 11.45=34.35\text{ liters}](https://tex.z-dn.net/?f=1%5Ctext%7B%20cubic%20inch%7D%3D3%5Ctext%7B%20liters%7D%5C%5C%5C%5C11.45%5Ctext%7B%20cubic%20inches%7D%3D3%5Ctimes%2011.45%3D34.35%5Ctext%7B%20liters%7D)
Hence, there are 34.35 liters left in the test tube.
Answer:
true for all real numbers
Step-by-step explanation:
Subtracting z from both sides gives ...
9 ≤ 19
This statement is true for all values of z. The solution is "all real numbers."
Answer:
<h2>9 12/25.</h2>
Step-by-step explanation:
9.48 as a mixed number in simplest form:
<em><u>948/100</u></em>
<em><u>948/100= 948 ÷ 4/100 ÷ 4</u></em>
<em><u>948/100= 948 ÷ 4/100 ÷ 4= 237/25</u></em>
<em><u>948/100= 948 ÷ 4/100 ÷ 4= 237/25= 9 12/25</u></em>
<u>9 12/25 is the mixed number.</u>
