That big triangle is made up of 2 congruent 30-60-90 triangles with each base measuring 4.5. You could use the tangent ratio to get tan60 = x / 4.5. Multiply both sides by 4.5 to get 4.5 tan60 = x. Do that on your calculator in degree mode to get that x = 7.79 or 7.8
Answer: Richard.
Step-by-step explanation: The question mark for Steve is 55, making the rate of change 110/2 or 55/1, or 1.
Geeta's pay's function is p=75+45h, and 75+45×1=120, 75+45×2=165, and 75+45×3=210. The rate of change for Geeta is 45/1, or 45.
Now, Richard's pay is easy. All u have 2 do is subtract 110-80=30, and subtract 80-50=30. His rate of change is 30/1, or 30.
Answer:
2 3/4
Step-by-step explanation:
To find the amount of time between two events, we can use subtraction, just like we do with regular subtraction problems. The subtraction will look something like this:
10:33
-
7:18
Like in a regular subtraction problem, we can subtract the digits that line up, like 10 and 7. Subtracting all of the corresponding digits, we get that it took Tony 3 hours and 15 minutes to finish baking the cookies.
