Answer: x = -3.5
Step-by-step explanation:
Since they are similar they should have the same ratio, so if four equals two, then 5 equals 2.5. Then you solve the equation 2.5 = x+5, to find x.
225 yards/ 5 trips = 45 yards per trip.
Final answer: 45 yards
Answer:
Step-by-step explanation:
Let's call the initial point and the second point we can find the distance between these two points with the following formula:
And if we replace we got:
So since we know the time in order to reach the point R we can find the velocity like this:
And this velocity is constant along all the displacement.
Let's call the final point
And we can find the distance between the point R and F like this:
And if we replace we got:
Since the velocity is constant we can find the time between point R and F like this:
And we are interested on "When will it pick up the ball located at position (28,35)?" And then the total time would be:
The figure attached illustrate the problem.
The formula for area of a circle is: πr^2
r is half the diameter.
FE is the diameter: r = 20/2 = 10
Area of circle using FE = π10^2 = π * 100 = 314 square meters.
BE is a radius:
Area = π3.5^2 = π * 12.25 = 38.465 = 38.5 square cm ( rounded to nearest tenth).
AB is a radius:
Area = π11^2 = π * 121 = 379.94 = 380 square feet ( rounded off).
EF is a diameter
r = 12/2 = 6 meters
Area = π6^2 = π * 36 = 113.04 = 113 square meters ( rounded off).
Answer:
Annuity C
Step-by-step explanation:
The longer the term, the greater the contribution that interest makes. If we simply assume there is an answer among these choices, it will be the choice with the longest term: Annuity C.

For n payments, the multiplier of the payment at 5% per year is ...
(1.05^n -1)/(0.05)
The attached graph shows this value exceeds 2n for n > 26.5. That is, for n=30, the interest earned is more than the amount contributed.
