Answer:

42 acres to 72 acres, there is an increase of 30 acres

percentage wise

72-42=30

30/72=.4166...

therefore there is also a 41.6% increase

Step-by-step explanation:

Now, the change is given from 42 acres to 72 acres, therefore

How can I make this a perfect square<br> w^2-4w+
Neporo4naja [7]
Ax^2+bx+c
if a=1, then
take 1/2 of b and square it

w^2-4w+c
b=-4
-4/2=-2, (-2)^2=4
add that
w^2-4w+4
(w-2)(w-2)
(w-2)^2

to make it into perfect squres, add 4

What is the probability of not rolling a number larger than 4 with a fair die?
Fiesta28 [93]
Find the probability of rolling a number bigger than 4 and subtract that by 100%; 

P(5)= 1/6 <-- 6 possible outcomes, 1, 2, 3, 4, 5 or 6
P(6)= 1/6 

You could have rolled a 5 or 6. When the word or is used, the probabilities are added together, when and is used, they are multiplied. 

(1/6)+(1/6)=2/6 

1-P(5)+P(6) 
=1-(2/6) 
=(6/6)-(2/6)
=4/6 

Therefore the probability of not rolling a number larger than 4 is 4/6 or 2/3.

Hope I helped :)

What is the length of the missing leg of a right triangle given a leg of length 8 and a hypotenuse of length 10. Leave your answ
bezimeni [28]

Answer:

6

Step-by-step explanation:

The hypotenuse will always be equal to "c." You can put "a" or "b" as 8. This gives us a^2 + 8^2 = 10^2 which simplifies to a^2 + 64 = 100. From there, you simplify (subtract 64, giving you a^2 = 36, and then take the square root of a^2 & 36 to get a = 6 (because 6*6 = 36))
