describe what happens when you divide a difference by 3

Answers

When you divide a difference by 3, you are essentially finding the average difference between two quantities and then dividing that value by 3.

For example, if you have two numbers a and b, and you want to find the difference between them, you would subtract b from a to get a - b. Dividing this difference by 3 would give you:

(a - b) / 3

This expression represents the average difference between a and b, divided by 3.

For instance, if a = 10 and b = 6, then the difference between a and b is 4. Dividing this difference by 3 gives us:

(10 - 6) / 3 = 4 / 3

Therefore, when you divide a difference by 3, you are finding the average difference between two quantities and then dividing that value by 3.

Sarah rolls two fair number cubes, each labeled 1 through 6. What is the probability of rolling a sum of 7?

Answers

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

What is the approximate perimeter of the figure? Use 3.14 for pi.

Answers

Answer:

34,28 ft

Step-by-step explanation:

This figure is formed from a rectangle and a semi-circle

Opposite sides of a rectangle are equal

This figure's perimeter is the sum of all side lengths:

2 sides of 12 ft

1 side of 4 ft

Half of the circumference

d (diameter) = 4 ft

r (radius) = 0,5 × 4 = 2 ft

First, we have to find the half of the circumference (C):

[tex]0.5c = (2\pi \times r[/tex])/2

[tex]0.5c = (2 \times 3.14 \times 2)/2 = 6,28[/tex]

Now, we can find the perimeter of the given figure:

P = 6,28 + 12 + 12 + 4 = 34,28 ft

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

walnuts are 2.5 and chocolate chips are 1.5

if it takes 10.5 bushels of grapes to make 30 quarts of jelly, how many bushels of grapes will it take to make 3,200 quarts of jelly

Answers

Answer:

it will take 1120 bushels of grapes to make 3200 quarts of jelly.

Step-by-step explanation:

We can use a proportion to solve this problem. If 10.5 bushels of grapes make 30 quarts of jelly, then we can write:

10.5 bushels / 30 quarts = x bushels / 3200 quarts

where x is the number of bushels of grapes needed to make 3200 quarts of jelly.

To solve for x, we can cross-multiply and simplify:

10.5 bushels * 3200 quarts = 30 quarts * x bushels

33600 bushels-quarts = 30x bushels-quarts

Dividing both sides by 30 bushels-quarts, we get:

x = 33600 bushels-quarts / 30 bushels-quarts

x = 1120 bushels

Answer: 2.26

Step-by-step explanation: The formula for finding out the radius of a cylinder when given the volume and height is (r) = √(V / π × h)

V is the volume, π is equal to 3.14, and h is the height

(r) = √(320/ π × 20)

(r) = √(320/ 3.14 × 20)

(r) = √(320/ 62.8)

(r) = √(5.09)

(r) = 2.256

when you round 2.256 to the nearest hundredth is 2.26 cm  

I hope this helps
