How do I get the answer 1/2•-3 4/7

1 answer:

5 0

First off, we need to convert the mixed fraction to "improper", and then just multiply linearly, let's do so,

$\bf \stackrel{mixed}{3\frac{4}{7}}\implies \cfrac{3\cdot 7+4}{7}\implies \stackrel{improper}{\cfrac{25}{7}}
\\\\\\
\cfrac{1}{2}\cdot \cfrac{25}{7}\implies \cfrac{1\cdot 25}{2\cdot 7}\implies \cfrac{25}{14}\implies 1\frac{11}{14}$

This is a simple dynamical system for whom the the solutions are given as

$S=R[\frac{(i+1)^n-1}{i}](i+1)$

putting values we get

S=2000[\frac{(1.03)^{30}-1}{0.03}](1.03)

= $98005.35

withdrawal of money takes place from one year after last payment

To determine the result we use the present value formula of an annuity date

$P = R\frac{1-(1+i)^{-n}}{i}{i+1}$

we need to calculate R so putting the values and solving for R we get

R= $6542.2356

he wanted to make another quilt with an area of 42 square feet what are its possible dimensions if they must be whole numbers. W

Ostrovityanka [42]

Area=legnth times width
42=legnth times width
a quilt is normally for a big bed probably at leas 3 feet wide
factor 42
42=2 times 3 tiesm 7
possible values are
2 by 21
3 by 14
6 by 7
I would go with the 6 by 7 format

On a coordinate plane, parallelogram H I J K is shown. Point H is at (negative 2, 2), point I is at (4, 3), point J is at (4, ne

Mrrafil [7]

<h3>Answer: Choice C. (1,0)</h3>

============================================================

Explanation:

Point H is at (-2,2) and J is at (4,-2)

Focusing on the x coordinates, the midpoint is (x1+x2)/2 = (-2+4)/2 = 1.

The y coordinates have a midpoint of (y1+y2)/2 = (2+(-2))/2 = 0.

The midpoint is at (1,0). That's why the answer is choice C.

--------------------------

This next section is optional.

Points I and K are located at (4,3) and (-2,-3) respectively

Averaging the x coordinates gets us (x1+x2)/2 = (4+(-2))/2 = 1

Doing the same for the y coordinates gets us (y1+y2)/2 = (3+(-3))/2 = 0

We end up with the same midpoint (1,0)

The midpoint being the same for both diagonals proves that each diagonal is bisected, ie cut in half.
