In a cookie recipe, for every 3 cups of flour, 2 teaspoons of vanilla is needed. How many teaspoons are needed for 5 cups of flo
AfilCa [17]

to find this answer we use proportional reasoning.

3 cups of flour:2 teaspoons of vanilla

3:2

if 5 cups of flour are used then we adjust the ratio to keep it proportional

the vanilla is 'x' because we don't know the value (yet)

5:x

then we set it up in an equation and solve

3/2=5/x

2 multiplied by 5 divided by 3     x=3.33

5:3.33

you need 3.33 teaspoons of vanilla for 5 cups of flour

A six-sided die is rolled find P (of an even number) don't forget to reduce fraction
velikii [3]

Answer:

P(even no.) = 0.5

Step-by-step explanation:

Using the Formula of Probability = \frac{Required  outcomes}{Total possible outcomes}

Total no. of outcomes when a six sided die is rolled are: 6 (as shown below)

1, 2, 3, 4, 5, 6

Required outcomes are only even number: 3 (as shown below)

2, 4, 6


Thus P(even no.) = \frac{3}{6} = \frac{1}{2} = 0.5

30. f(x) = 11x3 + 3x2 - 4x + 2 and g(x) = 5x3 - 7x + 2. What is f(x) – g(x)? Show all of your steps and
balandron [24]

Answer:

3x(2x^2 +x-1)

Step-by-step explanation:

f(x) = 11x^3 + 3x^2 - 4x + 2,

g(x) = 5x^3 - 7x + 2,

f(x) - g(x) =11x^3+3x^2-4x+2 - (5x^3-7x + 2)=

11x^3+3x^2 -4x+2-5x^3+7x-2=

(11x^3-5x^3)+3x^2+(-4x+7x)+(2-2)=

6x^3 +3x^2 - 3x=

3x(2x^2 +x-1)
