Answer:
6.76
Step-by-step explanation:
applying pythogorem theorem
a^2+b^2=c^2
5^2+b^2=13^2
25+b^2=169
b^2=169/25
b^2=6.76^2
b=6.76
One way is to make them all decimals or all fractions:
.5 .2 .35 .48 .80 are the numbers above changed to decimals.
I will make them the same length (two digit past the decimal point) to compare
.50 .20 .35 .48 and .80
Now it is easy to put them in order
.2 .35 .48 .5 and .80
Let's put them into all fractions
5/10 1/5 35/100 12/25 and 4/5
Instead of finding a common denominator let's try this:
Think of them as test scores - the person who got 1 out 5 did the worst
Next came the person who got only 35 out of 100 - they only did better than the one above (1/5)
12/25 is almost 1/2 but a little below half the questions right
5/10 is exactly half the questions right (so it is bigger than 12/25 by a little).
4/5 is the best score (and the only one who passed).
So 1/5, 35/100, 12/25, .5 and 4/5 are in order least to greatest and match the answer above in bold.
Answer:
A. -24
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a directly or proportional variation if it can be expressed in the form 
or 
In this problem we have
For x=-3, y=12
Find the value of the constant of proportionality k
substitute the given values
so
The linear equation is equal to
what is the value of y when x=6?
substitute the value of x in the linear equation and solve for y
43.3% All you need to do is move the decimal two places to the right and there you go.
