One-hundred people were surveyed to find if they owned a cat
r-ruslan [8.4K]

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

Point T is on line segment S U ‾ SU . Given T U = x − 1 , TU=x−1, S U = 3 x − 7 , SU=3x−7, and S T = x + 7 , ST=x+7, determine t
dangina [55]

Answer:

TU = 12

Step-by-step explanation:

Given

TU = x − 1

SU = 3x − 7

ST = x + 7

TU = ?

Then we can say that

SU = ST + TU

⇒  3x − 7 = (x + 7) + (x − 1)

⇒  3x − 7 = 2x + 6

⇒  x = 13

Finally, we get

TU = x − 1

⇒  TU = 13 - 1

⇒  TU = 12

Therefore,

ST = x + 7 = 13 + 7 = 20

SU = 3x − 7 = 3*(13) - 7 = 32

$14871.16 = 1.957% times x

write decimals as a decimal

 /0.01957       /0.01957  

$759,895.75 = x
