Dorian buys 2 pounds of almonds for $21.98 and 3 pounds of dried apricots for $26.25. Which is less expensive per pound? How much is less expensive?

Answers

Dried apricots are $2.24 per pound less expensive.

Step-by-step explanation:

Apricots are less expensive by $2.24 per pound.

Step-by-step explanation:

The cost of 2 pound of almonds for = $21.98

The cost of 1 pound of almonds =

                                                    = $10.99

The cost of 3 pounds dried apricots for = $26.25

The cost of 1 pound dried apricots =

                                                         = $8.75

Difference in cost per pound = 10.99 - 8.75

                                                 = $2.24

3lbs of apricot for $26.25 because they are 2.24 less that 2lbs of almonds for $21.98

Use the figure and flowchart proof to answer the question: Which theorem accurately completes Reason A?

A. Alternate Interior Angles Theorem
B. Corresponding Angles Theorem
C. Alternate Exterior Angles Theorem
D. Same-Side Interior Angles Theorem

Answers

Answer:I believe that it would answer D) same side interior angles.

Same side interior angles or consecutive angle always add up to 180 degrees

A cannot be because the angles that the diagram is telling us are not alternate interior angles, alternate interior angles would be angle UQR and angle QRZ

B cannot be because they are not corresponding and also they are not Alternate Exterior angles. Which left us with D.

Find a common multiple between 30 and 42 that is bigger than them.
(Note: I'm not finding the LCM I just need a multiple bigger than them)

Answers

Answer:

210

Step-by-step explanation:

GCF(30,42) = 6

LCM(30,42) = ( 30 × 42) / 6

LCM(30,42) = 1260 / 6

LCM(30,42) = 210

1260

1260 is a multiple of 30 and 42.
30(42)=1260,
multiplying both of these numbers means that the result will always be a common multiple.

Answer: -2r+8

Step-by-step explanation:

The price of Stock A at 9 A.M. was ​$13.64. Since​ then, the price has been increasing at the rate of ​$0.06 each hour. At noon the price of Stock B was ​$14.39. It begins to decrease at the rate of ​$0.11 each hour. If the two rates​ continue, in how many hours will the prices of the two stocks be the​ same?

Answers

Answer: In about 3 hours and 21 minutes the prices of the two stocks will be the same at $14.02

Step-by-step explanation: We can begin by calculating the value of stock A at noon by adding $.06 per hour or 3 hours, $0.18 to its 9am price. $13.64 + 0.18 = 13.82

Then set up the equation to find the point where the prices are equal:

x is the amount of time in hours.

.06x + 13.82 = -.11x + 14.39    

Add .11x to both sides and subtract 13.82 from both sides

.06x + .11x = 14.39 - 13.82

.17x = 0.57

x = 3.353 hours

To get minutes instead of a decimal, multiply .353 × 60 ≈ 21 minutes

The time is 3:21

The increase in price is for stock A is about $0.20

13.82 + .0.06(3.353) = $14.02

Stock B decreased by $0.37

14.39 - 0.11(3.353) = $14.02

f(10)=1.75r+9

Answers

Answer:

Simplifying

f(r) = 5 + 1.75r

Multiply f * r

fr = 5 + 1.75r

Solving

fr = 5 + 1.75r

Solving for variable 'f'.

Move all terms containing f to the left, all other terms to the right.

Divide each side by 'r'.

f = 5r-1 + 1.75

Simplifying

f = 5r-1 + 1.75

Reorder the terms:

f = 1.75 + 5r-1

Step-by-step explanation:

tada i think

Let's solve for f.

f(10)=1.75r+9

Step 1: Divide both sides by 10

10f/10 =1.75r+9/10

Answer : f=0.175r+9/10

Which equation is correctly rewritten to solve for y?
12y + d = –19y + t
A. Y= t+d/-7
B. Y= -7(t+d)
C. Y= t-d/31
D. Y= 31(t-d)

Answers

Answer:

C. y=(t-d)/31

Step-by-step explanation:

Step 1: Add 19y to both sides.

31y+d=t

Step 2: Add -d to both sides.

31y=t-d

Step 3: Divide both sides by 31.

y=(t-d)/31

Here is a double number line showing that it costs $3 to buy 2 bags of rice:

1. At this rate, how many bags of rice can you buy with $12? ___________

2. Find the cost per bag. _____________

3. How much do 20 bags of rice cost? _____________

Answers

Answer:

1. 8 bags of rice

2. $1.50 per bag

3. $30

Step-by-step explanation:

For #1, you set up the proportion 3 over 2 is equal to 12 over x and solve by cross multiplication. Then, you should get the answer of 8 bags. For #2, you do $3 divided by 2 to get the answer of $1.50. For #3, you use your answer from #2 and do 1.5 times 20 to get $30.

1. The cost of 12 bags of rice is 18 dollars.

2. Per bag of rice cots 1.5 dollars.

3. The cost of 20 bags of rice is 30 dollars.

What is a unitary method?

A unitary method is a mathematical technique for determining the value of a single unit then we can derive any no. of units by multiplying it by the single unit.

Given it costs 3 dollars for 2 bags of rice.

We know if we determine the cost of one bag of rice we can find out the cost of any no. bags of rice.

∴ 2 bags of rice cost 3 dollars,

So, 1 bag of rice cots (3/2) dollars = 1.5 dollars.

1. At the rate of 1.5 dollars per bag of rice 12 bags of rice will cost (1.5×12) dollars = 18 dollars.

2. The cost per bag of rice is 1.5 dollars.

3. The cost of 20 bags of rice is (1.5×20) dollars = 30 dollars.

A cylinder has a volume of 1884cm^3. Find the volume of a cone with the same radius and height as the cylinder

Answers

Answer:

628

Step-by-step explanation:

The volume V of a cylinder whose radius is r and height is h is given as

V = πr²h

The volume of a cone v of a radius r and height h is also given as

v = 1/3 πr²h

As such , given that the cylinder has a volume of 1,884 cm ³, the volume of a cone with the same radius and height as the cylinder

= 1/3 * 1,884 cm ³

= 628 cm ³
