Answer:
1. 3r - 2
2. 6x - 9
3. -10y + 29
4. 4x - 3
Step-by-step explanation:
i dont know how to explain. Sorry, i just learn about this today. I have the same exactly questions and here is the answer.
Answer:
1 minute and 4 seconds
Step-by-step explanation:
5 hours - 1hour 20mins = 3hours 40 mins
3 hours 40 mins = 220 minutes
236 / 220 = 1.07272... x0.6 x 100 = 64.36... seconds
1 minute and 4 seconds
Mid point formula =
(x1/2+x2/2, y1/2+y2/2)
x=
x+0 = 8
/2
x+0 = 8 x 2
x = 16
y=
y+(-2) = 1
/2
y-2 =1 x2
y=2+2
y=4
(16,4)
(In this case, the midpoint (x ,y) will be represent as the answer)
Answer:
Step-by-step explanation:
It will take 39.3 years for the balance of this account to reach $5000
Step-by-step explanation:
Formula for time (t)
t = ![\frac{ln(\frac{A}{P})}{n[ln(1+\frac{r}{n})]}](https://tex.z-dn.net/?f=%5Cfrac%7Bln%28%5Cfrac%7BA%7D%7BP%7D%29%7D%7Bn%5Bln%281%2B%5Cfrac%7Br%7D%7Bn%7D%29%5D%7D)
Where:
1. A = the value of the accrued investment/loan
2. P = the principal amount
3. r = the annual interest rate (decimal)
4. n = the number of times that interest is compounded per unit t
5. t = the time the money is invested or borrowed
∵ Olga invests $3000 in an account that earns 1.3% annual interest
compounded monthly
∴ P = $3000
∴ r = 1.3% = 1.3 ÷ 100 = 0.013 ⇒ annual interest
∴ n = 12 ⇒ compounded monthly
∵ The account will reach $5000
∴ A = 5000
- Substitute these values in the rule above
∴ t = ![\frac{ln(\frac{5000}{3000})}{12[ln(1+\frac{0.013}{12})]}](https://tex.z-dn.net/?f=%5Cfrac%7Bln%28%5Cfrac%7B5000%7D%7B3000%7D%29%7D%7B12%5Bln%281%2B%5Cfrac%7B0.013%7D%7B12%7D%29%5D%7D)
∴ t = 39.3 years
It will take 39.3 years for the balance of this account to reach $5000
