A rectangle has an area of 72 swaure units. The width of the rectangle is 9 units. The length of the rectangle is 2x + 4. What i

vichka [17]

Answer:

8 units

Step-by-step explanation:

Area of a rectangle = Width multiplied by Length

Substitute in all the known numbers into this formula to get

72 = (9) × $(2x+4)$

Solve the equation for x, to find out the length

$9(2x+4)=72$

$2x+4=72/9$

$2x+4=8$

$2x=8-4$

$2x=4$

$x=4/2$

$x=2$

Length of the rectangle = $(2x+4)$

$2(2)+4$

$4+4=8$

Suppose that a family wants to start a college fund for their child. If they can get a rate of 5.5% , compounded monthly,

chubhunter [2.5K]

The monthly deposit should be $81.38.

An ordinary annuity is a fixed payment made for a fixed amount of time at the end of each period.

The formula to determine the monthly deposit is:

Future value / annuity factor

Annuity factor = {[(1+r)^n] - 1} / r

Where:

r = interest rate = 5.5 / 12 = 0.4583%
n = 20 x 12 = 240

35,450 / [(1.004583)^240 - 1] / 0.004583 = $81.38
