Total amount of money received by David for working at his father's store = $50
Amount of money spent by David at the movies = $20
Amount of money spent by David buying comics books = $10
Amount of money spent by David buying candy = $5
Then
Total amount spent by David = (20 + 10 + 5) dollars
= 35 dollars
Amount of money saved by David = (50 - 35 ) dollars
= 15 dollars
So
The ratio of the amount of money David
spent to the amount of money David saved = 35:15
= 7:3
So the ratio of the amount of money David spent to the amount of money David saved is 7:3
Given:
![\log (5k+4)=8r](https://tex.z-dn.net/?f=%5Clog%20%285k%2B4%29%3D8r)
To find:
The exponential form of given equation.
Solution:
We have,
![\log (5k+4)=8r](https://tex.z-dn.net/?f=%5Clog%20%285k%2B4%29%3D8r)
According to the property of the logarithm,
![\log_ax=y\Rightarrow x=a^y](https://tex.z-dn.net/?f=%5Clog_ax%3Dy%5CRightarrow%20x%3Da%5Ey)
Using the above property of the logarithm, we get
Therefore, the required equation in exponential form is
.
Between 16 and 20 is 68%.....between 18 and 20 is half of that....so it would be 34%
Answer: 55.4
Step-by-step explanation:
Remember soh cah toa
tangent = adjacent/opposite
angle is 18 degrees
Opposite is 18
Adjacent is x
So tangent of 18 degrees = 18/x
Use calculator to find tangent of 18 =0.3249
So 0.3249 = 18/x
Reciprocal both sides
3.0777 = x/18
Multiply both sides by 18
x = 55.3983
