Answer:

$39,851.25

Step-by-step explanation:

If the sales increase at a rate of 9% per year, this means it will be 109% of the previous year's value since 100% + 9% = 109%

109% in decimal form = 109/100 = 1.09

Therefore, the exponential function is:

y = 20000 \cdot 1.09^x, where x is the number of years

So when x=8,  

y = 20000 \cdot 1.09^8=39851.252...

After 8 years, annual sales = $39,851.25

If a lawn measures 40 and 4/5 ft by 50 and 7/8ft how many square feet of seed will he need?
pychu [463]
So convert to improper fracitons (improper=x/y where x>y and the current one is mixed where it is in t s/f form) so

40 and 4/5=(40 times 5)/5 and 4/5=200/5 and 4/5=204/5

50 and 7/8=(50 times 8)/8 and 7/8=400/8 and 7/8=407/8

area=legnth times width
legnth =407/8
width=204/5
multiply 407/8 and 204/5

407/8 times 204/5=(407 times 204)/(8 times 5)=83028/40=2075.7 square feet

the answer is 2075.7 ft^2 of seed

PLEASE HURRY! this is financial algebra
Zina [86]

Answer:

6 years

Step-by-step explanation:

Simple interest= P.R.T

I = $1300

P = 18000 deposit

Rate = 1.19%

T = ?

Putting into the formula we have

1300 = 18000x1.19/100xT

1300 = 18000x0.0119xT

1300 = 214.2T

Divide through to get T

T = 1300/214.2

= 6.069

So when we approximate T = 6 years

It would take 6 years to make $1300 in interest
