The hypotenuse of a right triangle has a length of 14 units and a side that is 9 units long. Which equation can be used to find
the length of the remaining side?
2 answers:
Answer:
10.7 units
Step-by-step explanation:
This is actually quite straightforward.
You will need to apply the Pythagorean Theorem formula, which is , where we have a and c in this instance.
Here, c equals 14 and a equals 9, so we can substitute these values in.
.
Calculating 9 squared gives us 81 and 14 squared results in 196.
To isolate b, we subtract 81 from 196 resulting in 115.
Next, we need to determine the square root of 115, which gives us b, approximately 10.7 units.
Thus, the length of the remaining side measures 10.7 units.

Given :
Miki possesses 104 nickels and 88 dimes. She intends to sort her coins into sets where each set has an equal count of both nickels and dimes.
Last year, 216,000 cars were sold.
To Find :
An equation that can identify the number of trucks, t, sold the previous year.
Solution :
Let t represent the quantity of trucks sold and c represent the cars sold.
The statement indicates that the quantity of cars sold exceeded three times the trucks sold by 39,000.
Thus,
Plugging the value of c = 216000 into the equation above yields :
This gives us the solution we seek.
