I say hmm x is an unknown number x is the groups and y is number in the groups so add any first number then the second has to make 7 like 1+6=7 or 5+2=7 I hope it helps

Ms. Brooks put $1200 in a 3 retirement account that offers 8% interest compounded annually. Ms. Brooks makes no additional depos

Leona [35]

Answer:

$1,408.21.

Step-by-step explanation:

Since it is compounded annually we could use the formula

A=Pe^rt

We know that the initial amount she deposits is $1200, as stated by the problem. That is our P.

e is well, the e in your calculator which is approximately: 2.7182818284590452353602874713527

r is the rate which is 8%, although you must convert this into a decimal, which would be 0.08 as your r.

Lastly, t is the time, so in this case, 2 years.

And then plug in the values.

A=1200(e)^(0.08)(2)

A=1200(e)^(0.16)

A=1200(1.173510870991810235018611086892)

A=1,408.2130451901722820223333042704

Now since it is a money problem we must put it in the correct format.

A=$1,408.21

Two rectangles or similar one is 5 cm x 12 cm the long side of the second rectangle is 8 cm greater than twice is short side fin

NikAS [45]

Answer:

The length is 48

The width is 20

Step-by-step explanation:

When 2 rectangles (figures) are similar, the ratio of corresponding sides are equal.

This rectangle is 5 by 12, so the shorter side (corresponding to 5) to the longer side (corresponding to 12) would be the same ratio, 5:12.

Let shorter side be s, and

longer side be l

It says, long side is 8 greater than twice short, we can write this as:

$l=2s+8$

In similar rectangles, we have said the corresponding sides' ratio are equal, so we could write:

$\frac{s}{l}=\frac{5}{12}$

Now, we replace the new found expression for "l" onto this and cross multiply and solve for s first:

$\frac{s}{l}=\frac{5}{12}\\\frac{s}{2s+8}=\frac{5}{12}\\5(2s+8)=12*s\\10s+40=12s\\2s=40\\s=\frac{40}{2}\\s=20$

So the shorter side is 20. and hence the longer side would be:

l = 2s + 8

l = 2(20) + 8

l = 40 + 8

l = 48

The longer side is 48.

The length is 48

The width is 20
