18 hotdogs - 12 hotdog buns = 6 hotdug buns still needed

6 is the amount of hotdog buns needed.

You subtract 12 from 18 because you already have that amount of buns and need to see how many you need to get.

My brain is fried from this stuff :( Help!!!A cake shop bakes a variety of brownies. The top-selling brownies are ones with toppings of chocolate chip, walnuts, or both. A customer enters the store. The probability that the customer will pick both toppings is 0.4. What is the probability that they will pick neither the chocolate chip nor the walnut toppings?

Answers

Probabilities:
-Chocolate chip only: 0.2
- Walnut only: 0.1
- Both: 0.4
Total probability = 1
1 = 0.2 + 0.1 + 0.4 + x
x = 1 - 0.2 - 0.1 - 0.4= 0.3

X2-15x+50=0

Answers

Answer:

(x - 10)(x - 5)

Step-by-step explanation:

Well to factor X^2-15x+50

we need to find 2 numbers that multiply to get 50 and add to get -15.

-5 * -10 = 50

-5 + -10

x*x = x^2

Factored (x - 10)(x - 5)

Hope this helps :)

Answer:

(x - 10)(x - 5)

Step-by-step explanation:

Step 1- Find 2 numbers that multiply to be 50.

10 × 5

-10 × -5

25 × 2

-25 × -2

All these multiply to get 50.

But the numbers must also add up to be -15.

Step 2- Find the 2 numbers that also add up to be -15.

10 + 5 = 15

-10 + -5 = -15

25 + 2 = 27

-25 + -2 = -27

The correct equation would be - 10 + -5

The 2 number you would use when you factor would be -10 and -5

Step 3- Write the equation

You can write the equation as (x - 10)(x - 5)

Or you can also write it as (x - 5)(x - 10)

Semicircle arc AB,AC,BD and CD divide the circle above in to regions. The points shown along the diameter AD divided in to 6 equal parts. If AD=6 what is the total area of the shaded region?

Answers

Area semicircle = π * r^(2) / 2;

 the total area of the shaded region = 2 * [ π* ( BD / 2)^(2) / 2 - π* ( CD / 2)^(2) / 2 ] = 4π - 1π = 3π.
