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: 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

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: 8.

Step-by-step explanation:

The solve this expression, you have to use PEMDAS rules. PEMDAS stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. This means that the first thing that you have to do is what is in the parentheses. This is [6 + (4 x 3)]. As I explained before, you have to do multiplication before addition, thus you have to do 4 x 3 first. This is 12, so now you have 6 + 12 in parentheses. Add this to get 18. Now that you are done solving the things in parentheses, you can use the 20 that is outside of the parentheses. You then have 20 - 12. This is 8, so your answer is 8.

Step-by-step explanation:

Find angle 44° first    ( 136 + 44 = straight line = 180 degrees)

   then angle 1 = 180 - 44- 20 = 116°   ( three angles of triangle sum t0 180°)    

Answer:

m=100 N=4480 P=1706. Q= 213.25

Step-by-step explanation:

First divide 800/8= 100

100 is M

Undo division for 560x8= 4480

4480 is N

Add 100+560= 660

Solve to equations 6986/8= 873.25

subtract 873.25-660= 213.25

213.25 is Q so undo division 213.25x8= 1706

1706 is P

Add 800+4480+1706= 6986

6986 is the first part of the equation

Add 100+560+213.25= 873.25

873.25 is the answer to the equation making answer that I gave correct

6986/8= 873.25

Step-by-step explanation:

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:

Given: [tex]4\frac{2}{6}[/tex] = [tex]3\frac{8}{6}[/tex]

First, convert the mixed fractions to improper ones:

[tex]\frac{26}{6}[/tex] = [tex]\frac{26}{6}[/tex]

When you look at them their proportional.

Answer:

When you look at them they're proportional.

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.

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:

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:

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

Answer: same as them

Step-by-step explanation:

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
