Answer:

$12.06

Step-by-step explanation:

In order to solve this, you must put both interest rates with the initial deposit into the compounded interest equation: A = P (1+r/n)^nt.

Bank of Canada:

P (principle amount deposited) = 4800

r (interest rate) = 2.4% or .024

n (number of terms compouded per year) = 1

t (total number of year) 8

A = 4800 (1+.024)^8

A = $5802.84

TD Bank:

P (principle amount deposited) = 4800

r (interest rate) = 2.4% or .024

n (number of terms compouded per year) = 12

t (total number of year) 8

A = 4800 (1+.024/12)^12*8

A = 5814.90

If you invest with TD over bank of Canada you will receive $12.06 more.

Answer:

4xy See image.

Step-by-step explanation:

Remember for division questions to use Keep, Change, Flip. You will Keep the first term the same. Change the divide to times. And Flip the second term (turn it upside down, in math this is called the reciprocal)

Also, you need to know when you you get to the part where everything is times, then you times: top×top, and bottom×bottom.

Once everything is times, you can rearrange the order and cancel (cancel is not really the mathy thing happening, you are dividing---

x/x is 1 and y/y is 1,

10/5 is 2, 6/3 is 2) See image.

The ratio of votes for Caleb to votes for Tyler in an election is 18:1. There were a total of 1995 votes. How many people voted
Sergeeva-Olga [200]
Tyler got 1/(18 +1) = 1/19 of the 1995 votes, so 1995/19 = 105 votes.

Please help. I've been trying to figure this out for an hour and I still don't understand how it's 72. I feel really stupid beca
rosijanka [135]

Answer:

C. 72\pi

Step-by-step explanation:

The radius of the circle is 24 units, then the area of the whole circle is

\pi r^2=\pi \cdot 24^2=576\pi \ un^2.

The shaded circle is limited by 45° angle, so its area is

\dfrac{45}{360}=\dfrac{1}{8}

of the area of the whole circle.

The area of the shaded circle is

\dfrac{1}{8}\cdot 576\pi =72\pi \ un^2.

A.) The formula for the volume of a sphere is given below and the relationship between the radius r and the diameter d is r=d/2.
Tasya [4]

Answer:

\displaystyle V=\frac{4}{81}\cdot \pi\ cm^3

Step-by-step explanation:

<u>The Volume of a Sphere </u>

The volume of a sphere of radius r is given by:

\displaystyle V=\frac{4}{3}\cdot \pi\cdot r^3

A. )

If the diameter of the sphere is d, the radius is r=d/2. Substituting:

\displaystyle V=\frac{4}{3}\cdot \pi\cdot \left (\frac{d}{2}  \right )^3

Operating

\displaystyle V=\frac{4}{3}\cdot \pi\cdot \frac{d^3}{8}

Simplifying

\displaystyle V=\frac{1}{6}\cdot \pi\cdot d^3

B.)

The diameter of the sphere is 2/3 cm, thus the volume is:

\displaystyle V=\frac{1}{6}\cdot \pi\cdot \left (\frac{2}{3}  \right )^3

Operating:

\displaystyle V=\frac{1}{6}\cdot \pi\cdot \frac{8}{27}

\displaystyle V=\frac{8}{27}\frac{1}{6}\cdot \pi

\boxed{\displaystyle V=\frac{4}{81}\cdot \pi\ cm^3}
