Pretty sure it’s 20degrees so D!!
Answer:
D*1.2 (OR) 1.2D
Step-by-step explanation:
Because the new menu has one hundred percent of the original menu (D), plus twenty percent, the new menu is 120%, or 1.2
You can then multiply the number of items on the original menu (D), by the new menu's value, which is 1.2 (or 120%).
This brings you to the answer of 1.2D
A quadratic is an expression of the form ax²+bx+c.
If the quadratic is in the perfect square form, it could be factored to look something like this:
(x+a)² or (x-a)²
Both of the above forms have one solution, that is "-a" and "a" respectively.
So if your quadratic equation is of the form:
(x±a)² = b, where b > 0
You can solve for "x" by taking the square root of both sides and getting 2 solutions -- ±a±√b.
And if your quadratic equation is of the form:
(x±a)² = b, where b < 0
Then when you try taking the square root of both sides, you will have to take the square root of a negative number, which means you will not get a real solution. Therefore, there will be zero solutions.
And finally if your quadratic equation is of the form:
(x±a)² = b, where b = 0
Then you will have one solution -- ±a.
Hope that helps!
The answer is (4, -6), or the fourth option.
To convert 0.45 to percent multiply by 100
<span>0.45 × 100 = </span>45 %
<span>Write the decimal number as a fraction
(over 1)
0.45 = 0.45 / 1
Multiplying by 1 to eliminate 2 decimal places
we multiply top and bottom by 2 10's
Numerator (N)
N = 0.45 × 10 × 10 = 45
Denominator (D)
D = 1 × 10 × 10 = 100
N / D = 45 / 100
Simplifying our fraction
= 45/100
= 9/20
