Answer:
27.4 yards
Explanation:
The diagonal of a rectangle, one of it's length and one of it's width will form a right angle triangle
Let
Width = x
Length = 2x
Diagonal = 80 yards
c^2 = a^2 + b^2
Where
c= diagonal
a= length
b= width
c^2 = a^2 + b^2
80^2 = (2x)^2 + (x)^2
80^2 = 2x * 2x + x^2
80^2 = 4x^2 + x^2
6,400= 5x^2
Divide both sides by 5
x^2= 6400 / 5
= 1280
x^2 = 1,280
Find the square root of both sides
√x^2 = √1,280
x= 35.8
How many yards, to the nearest tenth of a yard, does a person save by walking diagonally across the land instead of walking its length and its width?
Yards saved= (Length + width) - diagonal
= (2x+x) - 80
= {2(35.8) + 35.8} - 80
= (71.6 + 35.8) - 80
= 107.4 - 80
= 27.4
Yards saved = 27.4 yards
At best, I would recommend a code of ethics for the press to
follow regarding celebrities. The
problem is enforcing these codes as many of these journalists would like to
catch celebrities when they least expect it.
Also there are publications that pay for these kinds of photos and
articles as sensationalism sells. It
needs to be discourage but how is the problem.
Answer:
b. most research in social psychology builds off of prior research relatively slowly and systematically
Explanation:
Social psychology studies the psychology of a group of individuals in a called a society. Social psychologists studies the effect that the group has on the individual and the effect that the individual has on the group.
Social psychologists hypothesize how and why the effects take place. Then these hypothesis are tested by the social psychologist who first proposed the hypothesis, then if the hypothesis holds true the hypothesis is accepted.
This hypothesis is then tested in different situations and if the hypothesis still holds true the hypothesis becomes accepted widely. If the hypothesis does not hold true modifications are suggested after which the modified hypothesis is tested. If the modified hypothesis holds true then the modified hypothesis is accepted and the previous hypothesis is corrected.
The answer should be letter choice B
