Miguel's coffee shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Miguel $5.95 per pound, and Type B coffee costs $4.65 per pound. This month's blend used three times as many pounds of Type B coffee as Type A, for a total cost of $796.00. How many pounds of Type A coffee were used?

Answers

Answer:  40 lb of Type A

Step-by-step explanation:3 pounds of Type B and 1 pound of Type A will give 4 pounds of mix at a cost of ...  3($4.65) +($5.95) = $19.90Then $796 is the cost equivalent of 796/19.90 = 40 times that 4-lb mix. Since each instance of that 4-lb mix has 1 lb of Type A, $796 worth of blend has 40 lb of Type A coffee._____Additional commentIf you'd like to do this using a variable, you can let 'a' represent the amount of Type A coffee used. Then (3a) is the amount of Type B, and the total cost is ...  5.95a +4.65(3a) = 796  19.90a = 796 . . . . . . . . simplify  a = 796/19.90 = 40 . . . as above___There will be 120 lb of Type B coffee in that amount of blend.

The amount of Type A coffee that were used is 40 pounds.

What are word problems in Algebra?

Word problems in Algebra can be solved by correctly identifying the parameters given and the one(s) meant to be solved with the appropriate use of arithmetic operations.

From the given information;

Type A coffee costs Miguel $5.95 per poundType B coffee costs $4.65 per pound.

For this month, the equation can be expressed as:

A + 3A

Thus;

5.95A + 3(4.65)A = 796.005.95A +13.95A = 796.0019.9A = 796.00A = 796.00/19.9A = 40

Therefore, we can conclude that the amount of pounds of type A coffee that were used is 40 pounds.

If there are 2.54 centimeters in 1 inch, how long in inches is a meter stick? Hint: There are 100 centimeters in 1 meter. Round your answer to the nearest hundredth.

Answers

Answer:

i dont know that well but i do know 1 meter is roughly 2ft, so id say about 25.5 inches

0.01 inch is the  length of a meter stick.

To find the length of a meter stick in inches, we can use the conversion factor:

1 meter = 100 centimeters

1 inch = 2.54 centimeters

We can set up the proportion:

1 meter / 100 centimeters = x inches / 1 inch

Cross-multiplying:

1 meter × 1 inch = 100 centimeters × x inches

x = (1 meter × 1 inch) / (100 centimeters)

x = 1 inch / 100

x = 0.01 inch

It takes 60 pounds of seed to completely plant a 7-acre field. How many acres can be planted per pound of seed?

Answers

Answer:

7/60 acres

Step-by-step explanation:

60 pounds of seed = 7 acres

We want to find acres per pound of seed, so we want to make one side of the equation equal to 1 pound of seed. To do this, we can divide both sides by 60, as anything divided by itself equals 1. We thus have

60/60 pounds of seed = 7/60 acres

1 pound of seed = 7/60 acres

If 3,k,w,18 are in AP. Find the value of 3k + 4W

Answers

9514 1404 393

Answer:

  76

Step-by-step explanation:

For some common difference d, the terms of the progression are ...

  k = 3 +d

  w = k +d = 3 +2d

  18 = w +d = 3 +3d

Solving for d, we get ...

  15 = 3d . . . . subtract 3

  5 = d . . . . . . divide by 3

Now, we can find ...

  3k +4w = 3(3 +d) +4(3 +2d) = 9 +3d +12 +8d = 21 +11d

  3k +4w = 21 +11(5) . . . . substitute for d

  3k +4w = 76

Find the area of the sector of a circle with diameter 32 feet and an angle of 7Pi/4
radians.Round your answer to four decimal places.

Answers

Answer:

703.7168 ft²

Step-by-step explanation:

Use the sector area formula, a = 1/2r²θ

If the diameter is 32 feet, then the radius is 16 feet.

Plug in the radius and angle measure into the formula, and solve:

a = 1/2r²θ

a = 1/2(16)²(7[tex]\pi[/tex]/4)

a = 703.7168

So, the area of the sector is 703.7168 ft²

Answers

9514 1404 393

Answer:

  56th batch

Step-by-step explanation:

The least common multiple of 8 and 28 is 8·7 = 56. Tom and Larry will both test the 56th batch.

__

There are a couple of ways to find the least common multiple (LCM) of a pair of numbers.

1. Factor them and use the highest power of the unique factors.

  8 = 2³

  28 = 2²×7

Unique factors are 2 and 7. Their highest powers are 3 and 1, so the LCM is ...

  (2³)(7) = 56

__

2. Divide the product by the greatest common divisor (GCD). Here, both numbers are divisible by 4:

  8 = 4·2

  28 = 4·7

So, the LCM is 8×28/4 = 56.

Answer:

Step-by-step explanation:

8=2x2x2

28=2x2x7

lcm of 8,28= 56

excerpt from Of Plymouth Plantation by William BradfordAn Understanding with the Indians (1621)All this while the Indians came skulking about them, and would sometimes show themselves aloof off, but when any approached near them, they would run away. And once they stole away their tools where they had been at work and were gone to dinner. But about the 16th of March, a certain Indian came boldly amongst them and spoke to them in broken English, which they could well understand but marveled at it. At length they understood by discourse with him, that he was not of these parts, but belonged to the eastern parts where some English ships came to fish, with whom he was acquainted and could name sundry of them by their names, amongst whom he had got his language. He became profitable to them in acquainting them with many things concerning the state of the country in the east parts where he lived, which was afterwards profitable unto them; as also of the people here, of their names, number and strength, of their situation and distance from this place, and who was chief amongst them. His name was Samoset. He told them also of another Indian whose name was Squanto, a native of this place, who had been in England and could speak better English than himself.Being after some time of entertainment and gifts dismissed, a while after he came again, and five more with him, and they brought again all the tools that were stolen away before, and made way for the coming of their great Sachem, called Massasoit. Who, about four or five days after, came with the chief of his friends and other attendance, with the aforesaid Squanto. With whom, after friendly entertainment and some gifts given him, they made a peace with him (which hath now continued this 24 years) in these terms:That neither he nor any of his should injure or do hurt to any of their people.That if any of his did hurt to any of theirs, he should send the offender, that they might punish him.That if anything were taken away from any of theirs, he should cause it to be restored; and they should do the like to his.If any did unjustly war against him, they would aid him; if any did war against them, he should aid them.He should send to his neighbors confederates to certify them of this, that they might not wrong them, but might be likewise comprised in the conditions of peace.That when their men came to them, they should leave their bows and arrows behind them. After these things he returned to his place called Sowams, some 40 miles from this place, but Squanto continued with them and was their interpreter and was a special instrument sent of God for their good beyond their expectation. He directed them how to set their corn, where to take fish, and to procure other commodities, and was also their pilot to bring them to unknown places for their profit, and never left them till he died. He was a native of this place, and scarce any left alive besides himself. He was carried away with divers others by one Hunt, a master of a ship, who thought to sell them for slaves in Spain; but he got away for England and was entertained by a merchant in London, and employed to Newfoundland and other parts, and lastly brought hither into these parts by one Mr. Dermer, a gentleman employed by Sir Ferdinando Gorges and others for discovery and other designs in these parts.Readers can infer that Samosets visit to the community improves the relationship between the colony members and the Native Americans.Which detail from the passage best supports this inference? 1. He was a native of this place, and scarce any left alive besides himself.2. After these things he returned to his place called Sowams, some 40 miles from this place, but Squanto continued with them and was their interpreter3.
