Step-by-step explanation:To convert a meter per second measurement to a mile per hour measurement, multiply the speed by the conversion ratio. One meter per second is equal to 2.236936 miles per hour, so use this simple formula to convert:
Answer:
x = -7/2 and x = 1
So, there are 2 roots of this equation.
And the roots are real numbers.
Step-by-step explanation:
We need to describe the nature of roots for this equation
2x^2+5x-7=0
2x^2-2x+7x-7=0
2x(x-1)+7(x-1)=0
(2x+7)(x-1)=0
2x+7=0, x-1=0
2x=-7, x =1
x = -7/2 and x = 1
So, there are 2 roots of this equation.
And the roots are real numbers.
Answer:
the answer would be 12 minutes
Step-by-step explanation:
Answer:
Parenthesis, Exponents (& roots), Multiplication, Division, Addition, Subtraction.
This is the order you use when you need PEMDAS. For example, in this question:
(2 * 3) + 5(3)
First, you solve the parenthesis: 2 * 3 = 6
Next, you solve for multiplication: 5(3) = 15
Finally, you add: 6 + 15 = 21

9.9 squared is close to 10 squared therefore it is 100
100×1.79= 179
