Hi again I helped you on your last question, I love helping people. Anyway here's the answer!
16. 0.188 rounded nearest hundredth = 0.19
17. 0.455 rounded nearest hundredth = 0.46
18. 0.538 rounded nearest hundredth = 0.54
19. 0.417 rounded nearest hundredth = 0.42
20. 2.833 rounded nearest hundredth = 2.83
21. 3.667 rounded nearest hundredth = 3.67
Angle of taller building Tan 45° = opposite (height of the building)/
adjacent 50 feet (distance between Kathy and the taller building
Tan 45° = 1
Height of taller building from eye level = multiplying adjacent
50 feet * Angle (Tan 45°) 1 = 50 feet opposite
Angle of smaller building Tan 38° = 0.781
Height of smaller building from eye level = Angle * adjacent
50 feet = 39.06 feet
Difference of eye level from ground is 5 feet
Taller building height is 50 + 5
Total height of taller building is 55 feet.
Smaller building height is 39.06 + 5
Total height of smaller building is 44.06 feet

Given:
Principal (P)= $1,000
Rate of interest (R)= 4% = 0.04
Simple interest (I)= $100
To find:
The time for which she deposits $1000 into a savings account at 4% simple interest.
Solution:
The formula for simple interest is
On substituting P=1000, R=0.04 and I=100 in the above formula, we get
Divide both sides by 40.
Therefore, the required time is 2.5 years.
Answer: low
Step-by-step explanation: because there are more greens than red or might say 20%

Answer: B) 10pi</h3>
==========================================
Explanation:
AB is a diameter of the circle with point O in the center. This makes angle AOB to be 180 degrees. Consequently, arc ADB makes up 180 degrees of a full 360 degree circle (ie it makes up half of the circle since 180/360 = 1/2)
We're told that arc ADB is 15pi units long. Since arc ADB makes up half the circle, the full circle must therefore be 2*15pi = 30pi. This is the circumference.
------------------
We're also told that angle COB is 60 degrees. Let's find angle COA
(angleCOA) + (angleCOB) = 180
angleCOA = 180-(angleCOB)
angleCOA = 180-60
angleCOA = 120
Angle COA is 120 degrees
This makes up 120/360 = 1/3 of the full circle
So (1/3)*(circumference) = (1/3)*(30pi) = 10pi is the arc length of AC where we take the shorter path from A to C along the circle's edge.
