You have to add 2.52 and 1.26 and divide it by 18!
Answer:
The number would have to be added is 2
Step-by-step explanation:
To find the form of the completing square of the quadratic function:
- Divide the coefficient of x by 2
- Subtract the numerical term from the square of the quotient
Let us do these steps with our question
∵ x² - 2x - 1 = 0
→ Divide the coefficient of x by 2
∵ The coefficient of x is -2
∴ -2 ÷ 2 = -1
→ Square the -1
∵ (-1)² = 1
→ Subtract the numerical term from 1
∵ The numerical term = -1
∵ 1 - (-1) = 1 + 1 = 2
∴ We must add 2 to -1 to get 1
→ (x² - 2x - 1 + 2) - 2 = 0
→ (x² - 2x + 1) = 2
→ (x - 1)² = 2
The number would have to be added is 2
The answer is C) 8 cm squared.
That is because 64/8 = 8 cm squared. Hope this helps!!!
The answer would be 54 since there is only 180 degrees in a triangle so you subtract 90 and 36 from 180. You get 54
Answer:
$114.54
Step-by-step explanation:
In order to answer this question, we are going to have to do some multiplication :)
First, we will find out how much Maria got paid on Monday. In order to find this, we must multiply 5.1 hours by $9.20, so
5.1 * 9.20 = 46.92
We will be using this number a little later. Next, we have to find out how much Maria got paid on Tuesday, so we have to multiply 7.35 hours by $9.20, so
7.35 * 9.20 = 67.62
Now, we will combine the numbers:
67.62 + 46.92 = 114.54
Therefore, Maria earned $114.54 this week
Hope this helps :)
