B= 5/2 or in short form b= 2 1/2 or decimal form b=2.5
Answer:
Step-by-step explanation:
height of monument = 555 feet
Scale in/ft = 1 /25
So, 25 feet = 1 inch
1 feet = 1 /25 inch
555 feet = 555 /25 = 22.2 inch
It means that the height of monument is 22.2 inch on scale. As it is a decimal number so it is not a reasonable scale.
Answer:
Step-by-step explanation:
There are 24 marbles in the bag.
So,
There are 17 marbles that are either white and green.
Therefore,
"the probability of drawing a white marble" is 9/24
=0.375 or approximately as 37.5%.
Probability of drawing first white marble from the bag.
Now,
"The probability of drawing a green marble" is 8/24
=0.333 or approximately as 33.3%.
Probability of drawing a green marble.
Let x = our unknown number
10x = 600
Divide by 10 on both sides to isolate the variable x.
x = 600/10
x = 60
600 is 10 times as much as 60.
Answer:
-6i
Step-by-step explanation:
Complex roots always come in pairs, and those pairs are made up of a positive and a negative version. If 6i is a root, then its negative value, -6i, is also a root.
If you want to know the reasoning, it's along these lines: to even get a complex/imaginary root, we take the square root of a negative value. When you take the square root of any value, your answer is always "plus or minus" whatever the value is. The same thing holds for complex roots. In this case, the polynomial function likely factored to f(x) = (x+8)(x-1)(x^2+36). To solve that equation, you set every factor equal to zero and solve for the x's.
x + 8 = 0
x = -8
x - 1 = 0
x = 1
x^2 + 36 = 0
x^2 = -36 ... take the square root of both sides to get x alone
x = √-36 ... square root of an imaginary number produces the usual square root and an "i"
x = ±6i
