Answer:
7630
Step-by-step explanation:
We have that the distance of a comet from Earth is about 7.63*10³ .
This number is given in scientific notation.
We want to write this number in standard form.
Since we are multiplying by a power of 10, we move forward three times.
Therefore in standard form:
![7.63 \times {10}^{3} = 7630](https://tex.z-dn.net/?f=7.63%20%5Ctimes%20%20%7B10%7D%5E%7B3%7D%20%20%3D%207630)
-4/(x + 1) = -1/(x + 5)
this is a proportion so we cross multiply
-1(x + 1) = -4(x + 5)
-x - 1 = -4x - 20
-x + 4x = -20 + 1
3x = -19
x = -19/3
Rate = 5.5 miles/s
Time to reach 2 miles
2 / 5.5
0.364 s
There are 5 quarters and 3 dimes.
Let's illustrate it as ![\frac{5}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B3%7D)
Now adding 5 quarters and 5 dimes, we get
.
5/3 is not equal to 10/8 hence it no longers has the ratio of 5:3 but now has the ratio of 5:4
Answer:
Step-by-step explanation:
For a. the 14.7 represents the pressure that the air puts on you all the time.
For b. the d represents the depth you go under the surface of the water.
For c. we have to solve p(d) when d = 8:
p(8) = 14.7 + 0.445(8) so
p(8) = 14.7 + 3.56 and
p(8) = 18.26 psi
