percent change = ((new value) - (reference value))/(reference value) × 100%
... = (487 -65)/65 × 100%
... = 422/65 × 100%
... = 6.492 × 100%
... ≈ 649%
The gestation period of rhinos is 649% longer than the gestation period of dogs.
Answer: 2-(2x+40) or (2x+40)-2
Step-by-step explanation: If you wanted to solve the problem, you have to do the stuff in the parentheses before you do the stuff out of the parentheses. In the parentheses, you will have to solve 2x before you do anything else. When you solve 2x, the answer to that, add it to 40. Then the answer in the parentheses, subtract it by 2 and you can get the answer.
Answer:
Step-by-step explanation:
x2 = 36?
solution
x^2-(36)=0
Factoring: x2-36
Check : 36 is the square of 6
Check : x2 is the square of x1
Factorization is : (x + 6) • (x - 6)
(x + 6) • (x - 6) = 0
x+6 = 0
x = -6
x-6 = 0
add 6 to both side
x = 6
x = -6
The area means to multiply the length by the width.
let's solve.
14 1/2 x 13 1/4.
convert our fractions into decimals.
14 1/2 = 14.50
13 1/4 = 13.25
Now we can multiply properly.
14.50 x 13.25 = 192.125
since our shape is 2-Dimensional, our units are ^2.
Your area is:
192.25 ft^2
Answer:
A
Step-by-step explanation:
1/4 is 3/4 away from being 4/4 = 1.
