Answer:
900
Step-by-step explanation:
(n – 2)180 where n is the number of sides
since this is a 7 sided polygon
(7-2) * 180
5 * 180
900
Answer:
49
Step-by-step explanation:
Complementary angles always add up to 90 degrees, so make and equation. First, say that angle ABC and angle QRS add up to ninety degrees. Substitute the values to get 41 degrees plus angle QRS equals 90 degrees, and once you subtract 41 from both sides, you get angle QRS equals 49 degrees.

Answer:
The rate of interest for the investment is 4.7%
Step-by-step explanation:
Given as :
The interest amount for investment = I = $250
The investment amount = p = $3500
The time period for investment = 18 months = 1.5 years
Let The rate of interest applied = r%
<u>Now, From Compound Interest </u>
Amount = Principal ×
∵ Interest = Amount - Principal
So, I = A - p
Or, A = I + p
Or, A = $250 + $3500
i.e A = $3750
∴ A = p ×
Or, $3750 = $3500 ×
Or, =
Or, 1.071428 = =
Or, 1.047069 =
Or, 1.047069 - 1 =
Or, 0.047069 =
∴ r = 0.047069 × 100
i.e r = 4.7069
So, The rate of interest = r = 4.7%
Hence, The rate of interest for the investment is 4.7% Answer
Answer:
A: 18x+15
Step-by-step explanation:
5(4x+3)-2x
Distribute the 5
20x +15 - 2x
Combine like terms
20x-2x +15
18x +15
