To do this question, you simply add what the Vice President makes to how much more the President makes. $562,500+ $237,400=799,900.

Then value of gold is appreciating 18% every hour you were lucky enough to have gold coin which was worth $40 at the beginning o

Zepler [3.9K]

Answer:

The equation is $y=40(1.18)^{x}$

Step-by-step explanation:

The exponential growth equation is $y=a(1 + r)^{x}$ , where

a is the initial value (value y at x = 0)
r is the rate of increasing in decimal

∵ The value of gold is appreciating 18% every hour

∴ r = 18%

∵ 18% = $\frac{18}{100}$ = 0.18

∴ r = 0.18

∵ The gold coin was worth $40 at the beginning of the crisis

∴ The initial amount is $40

∴ a = 40

∵ y represents the value of the gold after x hours

∴ $y=a(1+r)^{x}$

- Substitute the values of a and r in the form above

∴ $y=40(1+0.18)^{x}$

∴ $y=40(1.18)^{x}$

The equation is $y=40(1.18)^{x}$

A tortoise is walking in the desert. It walks for 4.8 meters at a speed of 3 meters per minute. For how many minutes does it wal

It is normally smart to write out a diagram of some sort to help you visualize the situation. I made one for this situation, although it might now suit you as well as it would me.

The idea behind this problem is to make you understand rates. Rates being the same thing as a slope. If you have learned about that already then that will help a lot, but if you haven't then that's fine.

So we have 4.8m and we traveled at a speed of 3 meters per 1 minute. A rate you are probably pretty familiar with is mph. Which is Miles per Hour. Or if you don't live in the U.S. Kmph. Which is Kilometers per Hour.

What you do to solve these type of problems is you take the given value and you use the rate to get the value you want.

The easiest way to do this is to make sure the signs (Meters) "cancel" out.

4.8m * (1min / 3m)

To cancel something out you need to have it over itself. Here are a few examples:

3/3 = 1
4/4 = 1
100,000/100,000 = 1
598/598 = 1

In the case of units, such as meters. They go *poof* from the problem.
So we have this problem:
(4.8m*1 minute) / 3m = ? minutes

4.8/3 = 1.6

If you want the answer in fractional form... here is how you do it: (I won't explain it because you most likely won't need to do this, but if you want to know how to do it then just ask)

4(8/10)
4(4/5)
(24/5)/3
(24/5) * (1/3)

24/15
8/5 is our final fractional answer!

Need the answer to 2. 3. 7. 8. please help! Really confused on how to do this.

Oduvanchick [21]

2. $\overline{SV}||\overline{TU}$ (this is given in the first sentence)

3. $\angle XSV\cong\angle XUT$ and $\angle XVS\cong\angle XTU$ due to ...

7. ... the alternate interior angles theorem (which holds because $\overline{ST}$ and $\overline{TU}$ are parallel)

8. Because the above establishes that $\Delta SXT\cong\Delta UXV$ , which means $\overline{ST}||\overline{UV}$ , which in turn means $VUTS$ is a parallelogram.
