Answer: The Answer is "less than"
Step-by-step explanation:
To find the sum of a series, you find the difference between the first and last term, multiply that by the number of terms, then divide by 2.
For the even numbers, 2 is the first term and 200 is the 100th term (because 2+(100-1)2 is equal to 200). So, (100(2+202)/2 = 10100.
For the odd numbers, 1 is the first term and 201 is the 101th term (because 1+(101-1)2 is equal to 201). So, (101(1+202))/2 = 10251.5.
10100<10251.5 so the sum of the first 100 even numbers is less than the sum of the first odd 101 numbers.
Answer is D
Step by step explanation
Answer:
D. 850 square foot
Step-by-step explanation:
Area of a space is the length
multiply by the width
The area for the kitchen, dining, office and sunroom will be calculated independently and added together.
Note the word "and the office and sunroom are each 10 feet by 10 feet"
Kitchen area = 10 ft x 15ft= 150sqft
Living/Dining area = 20ftx25ft= 500sqft
Sunroom = 10ftx10ft= 100sqft
Office= 10ftx10ft=100sqft
Therefore total surface area is the cumulative of the 4 areas
150sqft+500sqft+100sqft+100sqft= 850sqft
Since (x - 2)° and (2x + 5)° represent a pair of supplementary angles, then their sum must be equal to 180°. Therefore, the two supplementary angles are 57° and 123°.
