Answer: the sum invested = $600
<u>Step-by-step explanation:</u>
Interest (I) = Principal (P) × rate (r) × time (t)
Original amount: I = P × r × 3
Increased by 1%: I + 18 = P × (1+ .01)r × 3
Substitute I with Prt and set the equations equal to each other to find r:
3Pr + 18 = 3.03Pr
Solve for Pr:
18 = 0.03Pr
<u> ÷0.03</u> <u>÷ 0.03 </u>
600 = Pr
Answer:
i think its a dialation
Step-by-step explanation:
Answer:
Step 1 : First, solve one linear equation for y in terms of x .
Step 2 : Then substitute that expression for y in the other linear equation. ...
Step 3 : Solve this, and you have the x -coordinate of the intersection.
Step 4 : Then plug in x to either equation to find the corresponding y -coordinate.
Step-by-step explanation:
As there are no given data to work with in this given problem, allow me to generally describe the steps involved in going about this type of problems.
If we are asked about rate, we simply divide the number of fuels (in gallons) used by the racing dragster by the time (in second) it takes for it to be consumed.
