Here's the equation for one year:
0.04(15000) + 15000
Because it is 9 years:
0.36(15000) + 15000
We can make it simpler:
1.36(15000)
Multiply:
20400
Their balance is $20400
Answer:
56
Step-by-step explanation:
b + a is 90 degrees.
90 plus 90 plus 124 is 304
360 - 304 is 56
It is true that the ratio 4/7 to 8/9 has a unit rate of 9/14.
In a unit rate, the denominator becomes 1. So we divide the numerator by the denominator to make it one.
Now according to the question we have been given two ratios which are 4/7 and 8/9.
We have to find the unit rate of 4/7 to 8/9. For this we will divide 4/7 by 8/9. We will get,’
= (4/7)/(8/9)
It can be written in a simpler way as
= (4*9)/(7*8)
= 36/56
Reducing it into a simple fraction we get,
= 9/14
Thus, the ratio 4/7 to 8/9 has a unit rate of 9/14. Hence the statement is true.

The equations that can be used are 10T + 5S = 190 and T + S = 30.
<h3><u>Equations</u></h3>
Given that the girls tennis team was interested in raising funds for an upcoming trip, and the team sold tumblers for $10 and sun hats for $5, and when the sales were over, the team had earned $190 and sold 30 total products, which included a mix of tumblers and hats, to determine which equations can be used to represent the situation, the following calculations must be made:
- T + S =190
- -It cannot be used because it has any relationship with the price of the products.
- 10T + 5S = 30
- -It cannot be used because it only considers the quantity variable.
- T + S = 30
- -It can be used as it shows the amount of products sold.
- 10T + 5S = 190
- -It can be used because it relates the total price to the quantity of each product.
- T + S = 15
- -It cannot be used because it only considers the price variable.
- 5T + 10S = 190
- -It cannot be used because it erroneously relates the price of each product.
Therefore, the equations that can be used are 10T + 5S = 190 and T + S = 30.
