Answer:

I believe the answer is -28

Step-by-step explanation

I gotchu bro

The answer is -28 because Liana starts at 25 below sea level (which is the same thing as -25) If she rises 9 feet, then you know to add because she is going up so your just gonna add. Next she descends 12 feet, so she went down, so subtract. So i know the answer is going to be -28 because -25+9 is -16, then imma subtract -16 and 12 so, -16 - 12= -28. There ye go

Howard’s uncle gave him $885 for his tenth birthday. The money was invested in a savings account with interest compounded at 12%
Stella [2.4K]
Principal Amount = P = $885
Amount Accumulated = A = $3500
Interest rate = r = 12% = 0.12
Compounding period in a year = n = 2
Time in years = t = ?

The formula for compounding is:

A=P(1+ \frac{r}{n})^{t*n}

Using the values, we get:

3500=885(1+ \frac{0.12}{2})^{2*t} \\  \\ 
 \frac{3500}{885} =(1.06)^{2t} \\  \\ 
log(\frac{3500}{885})=log((1.06)^{2t}) \\  \\ 
log(\frac{3500}{885})=2tlog(1.06) \\  \\ 
t= \frac{log(\frac{3500}{885})}{2log(1.06)}  \\  \\  \\ 
t=11.80

This means, it will take him 11.8 or approximately 12 years

MAVERICK [17]

Answer:

A

Step-by-step explanation:

5x - 10 > 15

Add 10 to each side

5x-10+10 >15+10

5x > 25

Divide each side by 5

5x/5 >25/5

x>5

There is a open circle at 5 and the line goes to the right since x is bigger
