To solve this problem, we are going to need to set up a proportion. Let's let x represent what we are trying to find, the number of teaspoons of vanilla needed for the cookie recipe when 5 cups of flour are used.
3 cups flour/1.5 tsp vanilla = 5 cups flour/x tsp vanilla
The easiest way to simplify a proportion like this is to cross multiply. This means taking the numerator of one fraction and multiplying it by the denominator of the other fraction and setting it equal to the product of the other numerator and denominator. This is modeled below:
3 * x = 5 * 1.5
The first thing we should do to simplify is multiply our values on both sides of the equation.
3x = 7.5
Next, we should divide both sides of the equation by 3 to get the variable x (what we are trying to figure out) by itself.
x = 2.5
This means that for 5 cups of flour, 2 1/2 teaspoons of vanilla are needed.
Hope this helps!
Y=-25 because the difference between 9 and -12 is 21. -4 minus 21 equals -25.
Answer:
6 plus 4 i times the square root of 5
Step-by-step explanation:
The given statement can be written as:
6+√-80
To solve √-80 re-write -80 as -1 * 80
Now √-80 =√-1 * 80
Now we can write it as:
6+ √-1 * √80
We know that √-1 = i
Thus it becomes:
6+ i√80
Now find the square root of 80
80 does not have a perfect square root
Its square root can be found as 80 = 4*4*5
Then,
6+i√4*4*5
Notice that 4 makes a pair.. So we will write it outside the square root
6+1*4√5
We will write it as:
6+4i√5
Thus the correct option is 6 plus 4 i times the square root of 5....
I'm thinking it's a parabola since you can cover a vast amount of apace within the parabola too.
(2,0)
2(2) - 3(0) = 4
10(2) - 15(0) = 20
