Argyle has $1000 in his savings account. He wants to save more money. He is
Thepotemich [5.8K]
You would use the formula P(1+r/n)^nt=A I explained it in the picture and if the number is growing it is 1+r/n and if it’s not it is 1-r/n. Also if you don’t know the formula you can do it year by year which I also showed but it will take a long time and it’s easy to make a mistake. The answer would be A because if you plug the numbers into the formula you will get 4045.56 for plan b then you subtract 3000 and round, getting 1046. It is the formula of exponential growth/decay if you want to research further.

A race track is made from two straights and two semicircles. The straights are 80m long. The race track has a total perimeter of
Dmitriy789 [7]

Answer:

76.4 m

Step-by-step explanation:

The race track has two straights and two semi circles.

Each straight is 80m

total perimeter for the straights is 80 * 2 = 160m

two semi circles which creates a full circle

perimeter of a full circle = \pi d

NB : (d) is the diameter

therefore we can find the value of the diameter

400 = 160 + \pi d

400- 160 = \pid

240 = \pid

d = 240/\pi

d = 76.394.....

<u>d = 76.4 m</u>

Solve x/5 - 1=7? help please !!
xxTIMURxx [149]
First, add 1 on both sides of the equation to begin to isolate x

x/5 = 8

Now, to isolate x, multiply both sides of the equation by 5/1

\frac{x}{5} · \frac{5}{1} = \frac{5x}{5} = x

x= 7 · 5/1 = 7 · 5 = 35

x = 35
