Answer:
400 yd
Step-by-step explanation:
It's a 3 - 4 - 5 triangle
If the hypotenuse is a multiple of 5 and another length is the same multiple of 3 or 4, the one left over will be the same multiple of the one that's left.
Hi! This might be long but I hope it helps!
1. 115. If q=4, then the equation tells us that 0.1d+(0.25)⋅4=12.5. Subtracting 1 from both sides gives 0.1d=11.5, so d=115.
2. 100. If q=10, then the equation tells us that 0.1d+(0.25)⋅10=12.5. Subtracting 2.5 from both sides gives 0.1d=10, so d=100.
3. Yes. If you know the number of quarters, then you can determine the number of dimes from the equation. We can even write the equation in a way that shows this: d=125−2.5q. The expression 125−2.5qrepresents the output—it is the rule that determines the output d from a given input q.

Answer
137.385
Step-by-step explanation:
What is 6.5% of 129?
First, you have to change 6.5% to a decimal which is 0.065.
Then, you have to multiply 0.065 times 129 which gives you 8.385.
Finally, you have to add that amount to 129 which gives you $137.385, and that is the total cost of the prom dress
