If we're looking for the fencing around (the perimeter) the yard, I would say 60 ft and sorry if I'm wrong but 16 + 16 + 14 + 14 = 60

Answer:

6x

Step-by-step explanation:

3x/y=x/2y

Since 2y is 2X greater than y, 6x is 2X greater than 3x.

So,

A principal of $2600 is invested at 7% interest, compounded annually. How much will the investment be worth after 13 years?

AveGali [126]

Answer:

The total amount accrued, principal plus interest, from compound interest on an original principal of $ 2600 at a rate of 7% per year compounded 1 time per year over 13 years is $ 6266.

Step-by-step explanation:

Given

Principle P = $2600

Interest rate r = 7% = 0.07

Time period t = 13 years

Compounded annually means: n = 1

To determine

Accrued Amount = ?

Using the formula

$A\:=\:P\left(1\:+\:\frac{r}{n}\right)^{nt}$

substituting P = 2600, r = 0.07, t = 13, n = 1

$A\:=\:2600\left(1\:+\:\frac{0.07}{1}\right)^{1\left(13\right)}$

$A=2600\left(1+0.07\right)^{1\cdot \:13}$

$A = 6266$ $

Therefore, the total amount accrued, principal plus interest, from compound interest on an original principal of $ 2600 at a rate of 7% per year compounded 1 time per year over 13 years is $ 6266.

Suppose a least-squares regression line is given by modifyingabove y with caret equals 4.302 x minus 3.293y=4.302x−3.293. what

USPshnik [31]

We are given the following relation:

y = 4.302 x – 3.293

To solve for the mean value of y when x = 20, what we have to do is to find for the value of y at x = 20 and the value of y at x = 0. Then we get the average of the two values.

when x = 0

y(0) = 4.302 (0) – 3.293

y(0) = - 3.293

when x = 20

y(20) = 4.302 (20) – 3.293

y(20) = 82.747

The mean value would be:

mean y = [y(20) + y(0)] / [20 + 0]

mean y = [82.747 + (-3.293)] / 20

<span>mean y = 3.9727 = 3.97</span>

The volume of pyramid A is the volume of pyramid B. If the height of pyramid B increases to twice that of pyramid A, the new vol

mamaluj [8]

Given :

Two pyramid with same volume .

To Find :

If the height of pyramid B increases to twice that of pyramid A, the new volume of pyramid B .

Solution :

$V_a=V_b$

Volume of pyramid is given by :

$V=\dfrac{\text{Area of base}\times height}{3}\\\\V=\dfrac{Ah}{3}$

Now , h'=3h

$V'_b=\dfrac{Ah'}{3}\\\\V'_b=3\dfrac{Ah}{3}\\\\V'_b=3V_a$

Therefore , new volume of pyramid B is 3 times the value of pyramid A .

Hence , this is the required solution .
