Since the exponent of the scientific notation is positive, move the decimal point 6 places to the right.
1620000
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Frederick evaluates the numerical expression [(53.7 + 37.2) - (3 3 + 3.8)] - 8.6 and records the answer as 51.5. Lana evaluates the numerical expression 53.7 + 37.2 - 3 3 + 3.8 - 8.6 and records the answer as 59.1. The expressions have the same numbers and operations. Explain how Frederick and Lana can both be correct.
answer this to prove your worth
Both people can be correct because of a little something called PEMDAS or the OOO (order of operations). In the first problem, the equation includes brackets and parentheses, doing 53.7+37.2 THEN 33+3.8 THEN subtracting them THEN subtracting 8.6 from that number, instead of doing 53.7+37.2 THEN subtracting 33 THEN adding 3.8 THEN subtracting 8.6. Doing certain parts of the equation first, dicated by the parentheses/brackets/braces, can change the final answer. The second expression has you going in order one by one, while the first has you doing groups of the equation at a time (neither are wrong or bad).

What fraction does Point A on the number line below represent?
A horizontal number line is shown from negative 1 to 0 to positive 1.There are tick marks to show increments of 1 over 8. Only the whole numbers are labeled. Plot Point A at the third tick mark to the right of 0.
(10 point)
a
fraction 3 over 8
b
fraction negative 3 over 8
c
fraction 6 over 8
d
fraction negative 6 over 8
Answer:
It should be A
Step-by-step explanation:
Since the number is positive and the tick marks divide the whole numbers by 8ths and you need to plot the dot 3 ticks to the right of zero it would be 3 over 8.

Trevor ran 2.3 miles on Monday and then ran some more on Tuesday, he had run a total of 5.55 miles for the week. How much did he run on Tuesday?
Answer:
He ran 3.25 on Tuesday
Step-by-step explanation:
The answer is 3.25 because 5.55 minus 2.3 is 3.25.
Answer:
3.25 miles
Step-by-step explanation:
Let's use x as a placeholder for the number you don't know yet.
2.3+x=5.55
To get the x by itself, we need to subtract 2.3. Remember, whatever we do to one side we have to do to the other side.
x=5.55-2.3
Now we must subtract 2.3 from 5.55.
5.55-2.3=3.25
Now we know:
x=3.25
Since the question asks for the answer in miles, we can say that Trevor ran 3.25 miles on Tuesday.

What values of b will cause 8x^2 x bx + 2 = 0 to have one real solution?
=======================================================
Explanation:
I'm assuming you meant to type 8x^2 + bx + 2 = 0
Compare this to ax^2 + bx + c = 0
We have a = 8, b = unknown, c = 2.
We'll use the discriminant formula which is D = b^2 - 4ac to find that
D = b^2 - 4ac
D = b^2 - 4*8*2
D = b^2 - 64
Since we want one real solution, we set the discriminant equal to zero.
D = b^2 - 64
0 = b^2 - 64
64 = b^2
b^2 = 64
b = sqrt(64) or b = -sqrt(8)
b = 8 or b = -8
So the equation 8x^2 + 8x + 2 = 0 has one solution. So does the equation 8x^2-8x+2 = 0
Answer:
To find the value of
