It seems that you have missed the necessary options to answer this question, but anyway, here is the correct answer. To calculate a rewards program incentive, you use the simple interest formula. Using the simple interests formula, <span>A = P(1 + rt) where P is the Principal amount of money to be invested at an </span>Interest<span> Rate R% per period for t Number of Time Periods. Hope this helps.</span>
Answer:
That is the sort of question an 8-year-old might be asked to solve because it is so simple. time= 3 1/3 hrs to travel 100km, 1/3 of an hour is 20 minutes.
Answer:
<u>b) 95 degrees</u>
Step-by-step explanation:
Remember that the internal angles of a triangle add up to 180°.
Solving :
- 45° + 40° + ∠x = 180°
- ∠x + 85° = 180°
- ∠x = <u>95 degrees</u>
There is extra info here that could about drive you nuts. If you constructed right triangles from this scenerio, both the triangles would look identical. We have base angles of 90 (where the light goes into the ground, assuming the light pole is straight up in the air and not threatening to fall over on one of these people, ending their trig nightmare...) and another base angle of 28. We have the heights of these people as 6, so what we have is a right triangle with a base angle of 28 and a height across from that angle as 6. We need the length of the hypotenuse of this triangle which can be found very easily using the tangent sin ratio:
which gives us that x=12.78 feet
Answer:
<u>x = -7</u>
Step-by-step explanation:
Add 4 to both sides:
7x - 4 + 4 = 3 + 8x + 4
Simplify (The 4's cancel out)
7x = 8x + 7
Subtract 8x from both sides (The 8's cancel out)
7x - 8x = 8x + 7 -8x
Simplify:
-x = 7
Divide both sides by -1
-x/-1 = 7/-1
Simplify:
x = -7
Hope this helps!
