Answer:
38:81
Step-by-step explanation:
There are a total of 81 Astronauts in the space program.
Out of these, 43 are in outer space.
We are to determine the ratio of the number of astronauts on Earth to the total number of astronauts.
Number of Astronauts on Earth = Total Number - Number in Outer Space
=81-43 = 38
Therefore:
Number of astronauts on Earth : The total number of astronauts. = 38:81
Answer:
$80
Step-by-step explanation:
Area of Mr Jones's yard = 40 * 65 square feet
= 2600 square feet
Mr. Jones was charged $52 for the yard.
Therefore cost per square feet = 52/2600 = $0.02 per square feet
Area of neighbor's yard = 50 * 80 = 4000 square feet
Hence the neighbor will be charged 0.02 * 4000 = $80
For the area corresponding to the yard of size 4000 square feet, he will have to pay $80 to the landscaping company.
Plit the second term in 2{x}^{2}-x-12x2 −x−1 into two terms2{x}^{2}+x-2x-1=02x2 +x−2x−1=0
