a cookie recipe uses 6 cups of brown sugar for every 9 cups of white sugar. How many cups of brown sugar is needed if I use 24 c
Vlad1618 [11]

Answer:


Step-by-step explanation:

You can create a ratio from the provided recipe,

for every 6 cups of brown sugar you need 9 cups of white sugar so it would be 6:9

?:24

24/9=2.6

6x2.6=15.6

so for 24 cups of white sugar you would need about 16 cups of brown sugar.

Lapatulllka [165]

Answer:

I think 1/2

Step-by-step explanation:

Since there are 4 coins overall and 2 nickels, then the probabilty is 2/4

2/4 simplified is 1/2

(I've never been too good at probability so sorry if it is wrong)

Why do you need the answer so bad? Are you trying to get a pet?

3(3−3)=2(+3)−30 how do I do this???? I'm in 10th grade and this confuses me every time.
astra-53 [7]
Well when you simplify it you get this,

0=-24,


Do what’s inside the parentheses first

3-3 is 0, 3•0 is 0

2•positive 3 is 6

6- -30 is -24

So you have 0=-24

Or just -24 :)

Consider the function below. (If an answer does not exist, enter DNE.) f(x) = x3 − 27x + 3 (a) Find the interval of increase. (E
xxTIMURxx [149]

Answer:

(-∞,-3) and (3,∞)  

Step-by-step explanation:

f(x) = x³ − 27x + 3

1. Find the critical points

(a) Calculate the first derivative of the function.

f'(x) = 3x² -27  

(b) Factor the first derivative

f'(x)= 3(x² - 9) = 3(x + 3) (x - 3)

(c) Find the zeros

3(x + 3) (x - 3) = 0

x + 3 = 0      x - 3 = 0

     x = -3          x = 3

The critical points are at <em>x = -3</em> and x = 3.

2. Find the local extrema

(a) x = -3

f(x) = x³ − 27x + 3 = (-3)³ - 27(-3) + 3 = -27 +81 + 3 = 57

(b) x = 3

f(x) = x³ − 27x + 3 = 3³ - 27(3) + 3 = 27 - 81 + 3 = -51

The local extrema are at (-3,57) and (3,-51).

3, Identify the local extrema as maxima or minima

Test the first derivative (the slope) over the intervals (-∞, -3), (-3,3), (3,∞)

f'(-4) = 3x² -27 = 3(4)² - 27  = 21

f'(0) = 3(0)² -27 = -27

f'(4) = 3(4)² - 27 = 51

The function is increasing on the intervals (-∞,-3) and (3,∞).

The graph below shows the critical points of your function.
