Amir pits £3035 into a bank account. The account pays 4% compound interest each year. Work out how much money amir will have in

myrzilka [38]

Answer:

$\£3840.2$

Step-by-step explanation:

Let P denotes principal amount, T denotes time period and R denotes rate of interest.

Amount = $P(1+\frac{R}{100})^T$

Amir pits £3035 into a bank account. The account pays 4% compound interest each year.

Put $P=\£3035,\,R=4\%,\,T=6$

Amount = $3035(1+\frac{4}{100})^6=3035(\frac{104}{100})^6=\£3840.2$

Therefore, Amir will have $\£3840.2$ in the account after 6 years.

a container of candy is shaped like a cylinder and has a volume of 125.6 cubic centimeters. If the heights of the container is 1

Elenna [48]

The radius of the container is 2 centimeter

<h3><u>Solution:</u></h3>

Given that a container of candy is shaped like a cylinder

Given that volume = 125.6 cubic centimeters

Height of conatiner = 10 centimeter

To find: radius of the container

We can use volume of cylinder formula and obatin the radius value

<em><u>The volume of cylinder is given as:</u></em>

$\text {volume of cylinder }=\pi r^{2} h$

Where "r" is the radius of cylinder

"h" is the height of cylinder and $\pi$ is constant has value 3.14

Substituting the values in formula, we get

$\begin{array}{l}{125.6=3.14 \times r^{2} \times 10} \\\\ {r^{2}=\frac{125.6}{31.4}} \\\\ {r^{2}=4}\end{array}$

Taking square root on both sides,

$r = \sqrt{4}\\\\r = 2$

Thus the radius of the container is 2 centimeter

Anser number 6 for me so i kan get a better grade

Arlecino [84]

Answer:

Rita is left with approximately $\$ 4$

Step-by-step explanation:

Given:

Price for trousers= $\$ 19.39$

Price for shirt = $\$ 27.88$

Price for headscarf = $\$ 8.62$

Total Money she Spent = Price for trousers + Price for shirt + Price for headscarf = $\$ 19.39 + \$ 27.88+ \$ 8.62 = \$55.89$

Total Money she had before = $\$60$

∴Total Money left = Total Money she had - Total Money she spent = $\$60 - \$55.89 = \$4.11$

Rounding to nearest whole number ≈ $\$4$

Please help me, and please explain how you get to the answer.

Sliva [168]

the answer is 16

8^(4/3) can be written in different ways. You can first simplify it by breaking the exponents down into 1/3 and 4. You can write it as (8^1/3)^4 (it still means the same thing). When you raise something to the one over something fraction, the denominator tells you what the root is. Because it says 1/3, it means that you're finding the cube root of something. So you can rewrite it as (3√8)^4 (the three should be sitting on top of the sign to signify that it's cube root). You then just solve from there. The cube root of 8 is 2 (2*2*2=8) so it'll simplify to (2)^4. You then solve it from there and get 16 as your answer (2*2*2*2=16).
