Option 4
Expression that represent the approximate amount of people the smaller stadium can hold is
<em><u>Solution:</u></em>
Given that larger stadium can hold people which is about 15 times as many people as the smaller stadium can hold
To find: Expression that represent the approximate amount of people the smaller stadium can hold
From given information,
Number of people larger stadium hold = 15 times as many people as the smaller stadium can hold
Number of people larger stadium hold = 15 x (Number of people smaller stadium hold)
Which can also be expressed as:
To convert to scientific notation:
Move the decimal point in your number until there is only one non-zero digit to the left of the decimal point. The resulting decimal number is a.
Count how many places you moved the decimal point. This number is b.
If you moved the decimal to the left b is positive.
If you moved the decimal to the right b is negative.
If you did not need to move the decimal b = 0.
Write your scientific notation number as a x 10^b and read it as "a times 10 to the power of b."
So option 4 is correct
Answer:(2/3) + (9/10) = 47/30
= 1 17/30
Step-by-step explanation:
Answer:
Using division equality property to solve for b. b=27
Step-by-step explanation:
A book cost $3
Mr. Grayson spent $81 on books
Let number of books be b
Total cost invest on book = 3b
This would be equal to $81
Therefore, 3b=81
Now we solve for b
Using division method of equality
If we divide both side by same number in equality.After division we get both are equal .
3b=81
Here we divide by 3 both sides
3b÷3=81÷3
b=27
Thus, Using division equality property to solve for b. b=27
Answer:
45
Step-by-step explanation:
When you're completing the square you're adding (b/2)^2 which in this case is (-5)^2 or 25. This is because when you rewrite it as a square binomial you write it in the form (x+(b/2))^2 which is going to result in x^2+b+(b/2)^2. Since you need to reach 25 you need to add 45 since the last value is at -20.
