Answer:
The total amount of ribbon she had was 35 feet of ribbon.
Step-by-step explanation:
I hope this is one of the answers and I hope this helps you. Stay safe:)
L=2W+3, A=LW, using L from the first in the second gives you:
A=(2W+3)W
A=2W^2+3W, and we are told A=90 so
2W^2+3W=90
2W^2+3W-90=0
2W^2-12W+15W-90=0
2W(W-6)+15(W-6)=0
(2W+15)(W-6)=0, since W>0 for all real possibilities,
W=6ft, and since L=2W+3
L=15ft
So the pool will be 6 ft wide by 15 ft long.

Answer: B. Accurate but not reliable
Step-by-step explanation:
An experiment is said to be "reliable" when it consistently gives the same answers when done repeatedly, when the experiment is carried out several times it gives the same result each times.
An experiment is said to be " accurate "
when it produce a correct result using the right procedure and method .
In this case the research assessing a new screening tools for early identification of prostate cancer, test result is "accurate but not reliable ", since the consistent test result was not accurate.
The given vectors are 
and 
Two vectors are said to be orthogonal if they are perpendicular to each other. i.e. the dot product of the two vectors is zero.
Let us consider the dot product of the vectors
which is not equal to zero. Hence, the given vectors are not orthogonal.
Two vectors are said to be parallel if one vector is a scalar multiple of the other vector.
Here we can observe that the from the given vectors, one vector can not be expressed as the scalar multiple of the other vector.
Hence, the given vectors are neither parallel nor orthogonal.
