igomit [66]

Answer:

A) 1:4

Step-by-step explanation:

#We first calculate the campus' area:

a=lw\\\\=\frac{1}{4}\times \frac{1}{2}\\=0.125 \ mi^2

#We then calculate the campus' map area in square ft:

A=lw\\\\=0.5 \times 1\\\\=0.5 ft^2

Ratio is a comparison between two dimensions:

Ratio=\frac{0.125}{0.5}\\\\=0.25\\\\=\frac{1}{4}\\\\=1:4

Hence, the ratio of the area in square miles of the campus to the area in square feet of the map is 1:4

Complete the sentence below with less than,
Gekata [30.6K]

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.
