B Is the first one and I think 10 is A
Answer:
(–1, 1)
(4, –2)
Step-by-step explanation:
Let
(x,y) ----> the coordinates of point C
Applying the Pythagoras Theorem
step 1
Find the possibles values of x
Simplify
Solve the quadratic equation
The values of x are
x=-1 and x=4
step 2
Find the possibles values of y
Simplify
Solve the quadratic equation
The values of y are
y=-2, y=1
therefore
The possibles coordinates of point C are
(-1,1),(4,-2)
What are factors of -40?
(-20)(2)
(-10)(4) (sum of these factors is 6, which is not what we wanted)
(-5)(8) = -40 and the sum of the factors (-5) and (8) is 3.
{-5, 8} is the list of factors of -40 that add up to 3.
Answer:
1. I dont know what format they want you to write it in but its 27/100 which is 0.27 as a decimal and 27% as a percent
2. it'll be 11/100 which is 0.11 as a decimal and 11% as a percent
Step-by-step explanation:
Since adding up all the people with cats, dogs or both is 73, and theres 100 people surveyed, that means 100-73=27 so 27 people dont have a cat or dog. Therefore its 27/100 which is 0.27 as a decimal and 27% as a percent
For number 2, because 11 people have both a dog and cat I believe itll be 11/100 which is 0.11 as a decimal and 11% as a percent
