Altitude of mountain climber is 4572 and altitude of submarine commander is -609. What is the the difference in their altitude

1 answer:

8 0

To have a minus altitude or negative altitude you need to go below 0 ( which is represented by the sea level).

To get the difference between the mountain climber and submarine commander you add both altitudes as positive numbers: 4572 + 609 = 5181 m difference!

Another ex.

If a scuba diver is under the water, say 10 m hhe has a altitude of -10m

And a submarine is under at 100m that is a altitude of -100m.

The difference between the two is 100-10=90 m, not -90m. The difference is always a positive number.

Need Help. The question is down below

Useful Log Rules:

log(A*B) = log(A)+log(B) .......... log rule 1
log(A/B) = log(A) - log(B) .......... log rule 2
log(A^B) = B*log(A) ................... log rule 3

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

Part (a)

All logs shown below are base 3.

log(500) = log(5*100)

log(500) = log(5*10^2)

log(500) = log(5)+log(10^2) .... use log rule 1

log(500) = log(5) + 2*log(10) .... use log rule 3

log(500) = 1.4650 + 2*2.096 ....... substitution

log(500) = 5.657

<h3>Answer: 5.657</h3>

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

Part (b)

All logs shown below are base 3.

log(2) = log(10/5)

log(2) = log(10) - log(5) .... use log rule 2

log(2) = 2.096 - 1.4650 ....... substitution

log(2) = 0.631

<h3>Answer: 0.631</h3>

This is the two that go together, but are separate questions

Option 1)

6a + 8s = 102

14a + 4s = 150

each adult ticket costs 9 dollars

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

Explanation:

6 adult tickets and 8 student tickets bring in $102, so that means 6a+8s = 102

14 adult tickets and 4 students tickets bring in $150, so 14a+4s = 150

The system of equations is

$\begin{cases}6a+8s = 102\\14a+4s = 150\end{cases}$

If we multiply both sides of the second equation by -2, we get this updated system

$\begin{cases}6a+8s = 102\\-28a-8s = -300\end{cases}$

Add the equations straight down

6a+(-28a) = -22a

8s+(-8s) = 0s = 0 ... the 's' terms go away

102+(-300) = -198

So we end up with the equation -22a = -198 and that solves to a = 9 after dividing both sides by -22.

Each adult ticket costs $9

If you want the value of s, then

6a+8s = 102

6(9)+8s = 102

54 + 8s = 102

8s = 102-54

8s = 48

s = 48/8

s = 6

Meaning each student ticket costs $6

Or you could use the other equation

14a+4s = 150

14(9)+4s = 150

126+4s = 150

4s = 150-126

4s = 24

s = 24/4

s = 6

We get the same value of s

Please answer this multiple choice question for 30 points and brainliest!!

mixer [17]

Answer:

B. s = 0.85r

Step-by-step explanation:

The sale price is 15% off the regular price. In equation form, that is ...

s = r - 15%×r

s = r(1 - 0.15) = 0.85r

The equation that can be used to calculate the sale price is <em>s = 0.85r</em>.
