The constant of proportionality is: 0.2 and the equation is: c = 0.2t
Step-by-step explanation:
Let t be the number of texts and c be the cost
Then according to given statement
c ∝ t
The proportionality symbol will be removed and a constant f proportionality will be introduced.
![c = kt](https://tex.z-dn.net/?f=c%20%3D%20kt)
<u>For constant of proportionality:</u>
![3.20 = k * 16\\k = \frac{3.20}{16}\\k = 0.2](https://tex.z-dn.net/?f=3.20%20%3D%20k%20%2A%2016%5C%5Ck%20%3D%20%5Cfrac%7B3.20%7D%7B16%7D%5C%5Ck%20%3D%200.2)
Hence the constant of proportionality is 0.2

50% were invested in land, 10% were invested in stocks and 20% were invested in bonds.
Based on this, the total percentage of investments can be calculated as follows:
percentage of investments = 50% + 10% + 20% = 80%
The remaining percentage that was put into a saving account can be calculated as follows:
percentage of money in saving account = 100% - 80% = 20%
Now we know that the remaining is $35,000 represent the 20% of his money.
Assume his total amount of money is m, therefore:
20% x m = 35000
0.2m = 35,000
m = (35,000) / 0.2 = 175,000
Based on this, <span>the total amount of money that Mr. Rodriguez saves and invests is $175,000</span>
Answer:
a. sine
Step-by-step explanation:
As it can be seen from the figure, triangle ABC is the right-angled triangle with Angle C is equal to 90 degree.
In a right-angled triangle, there is a formula as following:
<em>+) sine (an acute angle) = (length of its opposite side)/ hypotenuse</em>
In the figure, angle B and length of the hypotenuse are given.
As x is the length of AC and AC is the opposite side to angle B
=> So that we can use sine to find x
Their are 3 numbers less than 4 on a die with 6 sides so 3 is 50% of 6 so then it should land on a number less than 4 50% of the 600 rolls to get 300
