if a * b = a^2 - b^3, then what is the value of 3 * -2

Answer: The probability is 1/6.

Step-by-step explanation:

If two dice are rolled together, the sample space of outcomes is

(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6),

(2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (2, 6),

(3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6),

(4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (4, 6)

(5, 1), (5, 2), (5, 3), (5, 4), (5, 5), (5, 6)

(6, 1), (6, 2), (6, 3), (6, 4) , (6, 5), (6, 6)

⇒ Total number of outcomes(sample space) = 36

Getting the sum 7 (favourable outcomes) = (1, 6), (2, 5), (3, 4), (4, 3), (5, 2), (6, 1).

⇒ Probability of Getting a sum 7 = Number of favourable outcomes / Total number of outcomes.

⇒ P = 6 / 36

⇒ P = 1 / 6

Answer:

Budget is the name given for the evaluation or speculative calculation of the cost of a work or service to be provided.

Step-by-step explanation:

The definition of a budget normally takes into account two main characteristics: the revenue, that is, the amount collected or available, and the expense, which would be the amount to be spent for the completion or maintenance of something. Budgets are present in various aspects of everyday life, from planning for a renovation of the house, to the amounts that will be earmarked for the maintenance of public government services, which directly or indirectly affect the lives of citizens.

Balancing a budget seems easy, but it requires a lot of self-control and discipline. Some strategies for achieving this balance are: do not spend more than what you earn, do not buy anything on impulse, do not borrow, renegotiate your debts and save on expenses that are superfluous.

Step-by-step explanation:

Killer whales in the Pacific are about 2.6 m long at birth. They grow at a rate of about 0.38 m per year, up to the age of 10 or more years. A marine biologist finds and rescues a 5-meter-long killer whale stranded on a beach. Based on this information, how old is the whale?

Length when found is the length at birth plus the product of age and yearly growth.

Answer:

¨Isaac has 1.17 pounds of cat food. He uses 0.13 pounds of cat food to feed one cat. How many cats can Isaac feed with the cat food he has?¨ the answer is 9

Answer:

9

Step-by-step explanation:

1.17 divided by 0.13

Step #1: 0.13 x 5 = .65

1.17 - 0.65 = 0.52

Step #2: 0.13 x 4 = 0.52

0.52 - 0.52 = 0

Step #3: 5 + 4 = 9.

1.58*2=3.06

4.20*6.99=29.36

4.38=4.38

3.06+29.36+4.38=36.8

40-36.8=3.2

Answer: $3.2

Heights of mountains are often measured in feet.

Answer:

Angle 4 is 151

Step-by-step explanation:

angle 3 and 4 form a straight line and since it is a straight line it equals 180 and since you know that angle 3 is 29 you subtract 180 - 29 = 151. And when you add that back up 29 + 151 = 180. So this is correct

Answer:

Step-by-step explanation:

1)13

it starts at 0 then +13

2)65

you put $65 in the bank

3)6

it jump 6 feet out of water and level of water is always 0 in this case

4)-13

the elevator goes down 13 from 0

5)-6

your sister has no money then she and own you $6 which put her in the negatives

6)-65

like i said in question 3 water is always 0 so you go down from 0 -65

Step-by-step explanation:

Answer:

walnuts cost $2.50 per pound, chocolate chips cost $1.50 per pound

Step-by-step explanation:

let w be the cost of 1 pound of walnuts

and c be the cost of 1 pound of chocolate chips

then

2w + 12c = 23 → (1)

5w + 3c = 17 → (2)

multiplying (2) by - 4 and adding to (1) will eliminate c

- 20w - 12c = - 68 → (3)

add (1) and (3) term by term to eliminate c

(2w - 20w) + (12c - 12c) = 23 - 68

- 18w + 0 = - 45

- 18w = - 45 ( divide both sides by - 18 )

w = 2.5

substitute w = 2.5 into either of the 2 equations and solve for c

substituting into (1)

2(2.5) + 12c = 23

5 + 12c = 23 ( subtract 5 from both sides )

12c = 18 ( divide both sides by 12 )

c = 1.5

then

cost of 1 pound of walnuts is $2.50

cost of 1 pound of chocolate chips is $1.50

Answer:

C

Step-by-step explanation:

Check the picture below.

so the shape on 2) is simply the shape of a rectangular prism underneath a  right-cylinder, now if we take the cylinder from the prism, we have the picture as you see below, so let's simply get the area of cylinder excepting  the bottom part, and then we'll take the area of the prism excepting the cylindrical part above it.

now, the area of the prism is simply the area of 6 rectangles, and the area of the cylinder is just the area of one circle above and the lateral area of it.

[tex]\stackrel{ \textit{\LARGE area of the prism} }{\stackrel{\textit{front and back}}{(25)(5)}+\stackrel{\textit{left and right}}{(25)(5)}+\stackrel{\textit{top and bottom}}{(25)(25)}~~ - ~~\stackrel{ \textit{excepted area} }{\pi (10)^2}} \\\\\\ 125+125+625~~ - ~~100\pi ~~\approx ~~ 560.84 \\\\[-0.35em] ~\dotfill[/tex]

[tex]\stackrel{ \textit{\LARGE area of the cylinder} }{\stackrel{ \textit{circular top} }{\pi (10)^2}~~ + ~~\stackrel{ \textit{lateral area} }{2\pi (10)(5)}}\implies 100\pi +100\pi ~~ \approx ~~ 628.32 \\\\[-0.35em] ~\dotfill\\\\ 560.84~~ + ~~628.32 ~~ \approx ~~ \text{\LARGE 1189.16}~cm^2[/tex]

1189.16 cm²

So the shape on 2) is simply the shape of a rectangular prism underneath a  right-cylinder, now if we take the cylinder from the prism, we have the picture as you see below, so let's simply get the area of cylinder excepting  the bottom part, and then we'll take the area of the prism excepting the cylindrical part above it.

Now, the area of the prism is simply the area of 6 rectangles, and the area of the cylinder is just the area of one circle above and the lateral area of it.

Area of the Prism = (25 * 5) + (25 * 5) + (25 * 25) - (100 * π)

                               = 125 + 125 + 625 - 100 π

                               = 560.84 cm²(Approximately)

Area of the cylinder = (π * 10²) + (2π * 10 * 5)

                                   = 100π + 100π

                                   = 628.32 cm² (Approximately)

Total area = Area of prism + Area of cylinder

                 = 560.84 + 628.32

                 = 1189.16 cm² (Approximately)

Answer:

  p = 12s -25

Step-by-step explanation:

You want an expression for Haddie's profit from the sale of s scarves when she has revenue of $12 each and a cost of $25.

Profit is the difference between revenue and cost. Haddie's revenue from sale of s scarves is ...

  revenue = 12s

Haddie's cost is the fee she pays for the booth rental:

  cost = 25

Her profit (p) is the difference between these values:

  profit = revenue - cost

  p = 12s -25
