The natural market sells a 12-ounce jar of peanut butter for $3.96. They also sell bulk peanut butter for $5.50 per pound. The ____ has a cheaper unit rate.

Answers

Answer:

The Jar of peanut butter

Step-by-step explanation:

The easiest way to do this is to calculate price per ounce of each unit.

We'll assign the 12 ounce jar to the variable s and the bulk to the variable b.

First create an equation to find the values of each product per ounce.

Since the 12 ounce jar(s) sells for 3.96 we can say it is 3.96 for every 12 ounces, or s = 3.96/12oz.

Simplify this equation and you get s = 0.33 per ounce.

For b we need to convert pounds to ounces.

There are 16 ounces per pound so the equation we get is:

b = 5.50/16oz

Simplified we get:

b =  about 0.34/oz

The smaller jar has a rate of $0.33/oz

The bulk has a rate of $0.34/oz

This means the answer is b. The jar of peanut butter has a cheaper unit rate.

While on a trip, you notice that the video screen on the airplane, in addition to showing movies and news, records your altitude (in kilometers) above the ground.

As the plane starts its descent
(at time x = 0), you record the following data: Time, x (min.) Altitude, y (km)
12 0 10 8 16 16 18 4 110 12

If you were to graph these points on a graph, you would notice that the line that forms represents a linear function. What is the practical meaning of slope in this situation?

a. For every minute that passes, the airplane descends 1 kilometer.

How to find the rate of change of a linear equation?

Suppose that the considered linear equation is of the form

y=mx+c

Then, when we change x by 1 unit, then:

The rate of change is the slope. The formula for slope is

m = y2 - y1 / x2 - x1

Using the first two points, (0, 12) and (2, 10), we have

m = (10-12)/(2-0)

m  = -2/2

m = -1

This means the plane descends 1 km per minute which means in 3 minutes' time, the plane descends 3 km.

Therefore, option a. For every minute that passes, the airplane descends 1 kilometer.

if 50% is 7 what is 25%, 75%, and 100%​

Answers

Answer:

100% = 14

75% = 10.5

25% = 3.5

Answer:

100% = 1475% = 10 1/250% = 725% = 3 1/2

Step-by-step explanation:

50% if a number is also 1/2 of that number. So, we multiply 7 by 2 to get 14.

Now we know that we need to solve for 25%, 75%, and 100% of 14.

100% of a number is just that number, so 100% of 14 is 14.

To solve for 75% of 14, we multiply 3/4 by 14.

3/4 x 14/1 = 42/4 = 10 1/2

The final number to solve for is 25% of 14.

1/4 x 14/1 = 14/4 = 3 1/2

A department store is having a clothing sale. If a $35.00 pair of pants has a discount tag of 20% off, what is the sale price?

Answers

Answer:

$28.00

Step-by-step explanation:

You start with 35.00.

Now 10% of this is 3.5.

Multiply by 2 because it's 20%.

You get 7, so 7 is 20% of 35.00.

35.00 minus 7 is 28.00.

The pair of pants will be 28.00 dollars!

Any help appriciated!

Answers

Step-by-step explanation:

The area of a circle is given by :

A = πr²

r is the radius of the circle

(4) Diameter = 22 cm

Since, radius = diameter/2

r = 11 cm

Now, area of the circle,

[tex]A=\pi \times (11)^2\\\\A=380.13\ cm^2[/tex]

(5) Diameter = 30 cm

Since, radius = diameter/2

r = 15 cm

Now, area of the circle,

[tex]A=\pi \times (15)^2\\\\A=706.85\ cm^2[/tex]

(6) Diameter = 4cm

Since, radius = diameter/2

r = 2 cm

Now, area of the circle,

[tex]A=\pi \times (2)^2\\\\A=12.56\ cm^2[/tex]

So, the area of circles 4,5 and 6 are 380.13², 706.85² and 12.56² respectively.

A patient needs a total dose of 50 grams of albumin. The pharmacy has 50 m
bottles of 25% Albumin in stock. How many bottles should the pharmacy
technician prepare to provide the required dose?

Answers

Answer : The number of bottles should the pharmacy  technician prepare to provide the required dose are 4 bottles.

Step-by-step explanation :

As we are given that a patient needs a total dose of 50 grams of albumin and the pharmacy has 50 mL bottles of 25% Albumin in stock.

Now we have to determine the number of bottles should the pharmacy  technician prepare to provide the required dose.

As,

The pharmacy  has stock albumin = [tex]50mL\times \frac{25}{100}[/tex]

The pharmacy  has stock albumin = 12.5 mL

So,

Number of bottles should the pharmacy  technician prepare to provide the required dose = [tex]\frac{50}{12.5}[/tex]

Number of bottles should the pharmacy  technician prepare to provide the required dose = 4

Therefore, the number of bottles should the pharmacy  technician prepare to provide the required dose are 4 bottles.

Though near the midnight hour, it was bright day as he passed through the weary camp. Many saw him, all knew him, but few and cold were the greetings he received."Negore, the Coward," he heard Illiha, a young woman, laugh, and Sun-ne, his sister's daughter, laughed with her.Black anger ate at his heart; but he gave no sign, threading his way among the camp-fires until he came to one where sat an old man. A young woman was kneading with skillful fingers the tired muscles of his legs. He raised a sightless face and listened intently as Negore's foot crackled a dead twig."Who comes?" he queried in a thin, tremulous voice."Negore," said the young woman, scarcely looking up from her task.Negore's face was expressionless. For many minutes he stood and waited. The old man's head had sunk back upon his chest. The young woman pressed and prodded the wasted muscles, resting her body on her knees, her bowed head hidden as in a cloud by her black wealth of hair. Negore watched the supple body, bending at the hips as a lynx's body might bend, pliant as a young willow stalk, and, withal, strong as only youth is strong. He looked, and was aware of a great yearning, akin in sensation to physical hunger. At last he spoke, saying:"Is there no greeting for Negore, who has been long gone and has but now come back?""Thou art my woman, Oona," Negore said, his tones dominant and conveying a hint of menace.She arose with catlike ease and suddenness to her full height, her eyes flashing, her nostrils quivering like a deer's."I was thy woman to be, Negore, but thou art a coward; the daughter of Old Kinoos mates not with a coward!""Old Kinoos and I came among you from a strange land. Thy people took us in by their fires and made us warm, nor asked whence or why we wandered. It was their thought that Old Kinoos had lost the sight of his eyes from age; nor did Old Kinoos say otherwise, nor did I, his daughter. Old Kinoos is a brave man, but Old Kinoos was never a boaster. And now, when I tell thee of how his blindness came to be, thou wilt know, beyond question, that the daughter of Kinoos cannot mother the children of a coward such as thou art, Negore."Again she silenced the speech that rushed up to his tongue."Know, Negore, if journey be added unto journey of all thy journeyings through this land, thou wouldst not come to the unknown Sitka on the Great Salt Sea. In that place there be many Russian folk, and their rule is harsh. And from Sitka, Old Kinoos, who was Young Kinoos in those days, fled away with me, a babe in his arms, along the islands in the midst of the sea. My mother dead tells the tale of his wrong; a Russian, dead with a spear through breast and back, tells the tale of the vengeance of Kinoos."But wherever we fled, and however far we fled, always did we find the hated Russian folk. Kinoos was unafraid, but the sight of them was a hurt to his eyes; so we fled on and on, through the seas and years, till we came to the Great Fog Sea"At last we came to Pastolik, which is where the Yukon drowns itself in the Great Fog Sea."So, when there came a ship, Old Kinoos stepped forward and said he would show the way. He was an old man then, and his hair was white; but he was unafraid. And he was cunning, for he took the ship to where the sea sucks in to the land and the waves beat white on the mountain called Romanoff. The sea sucked the ship in to where the waves beat white, and it ground upon the rocks and broke open its sides. Then came all the people of Pastolik, (for this was the plan), with their war-spears, and arrows, and some few guns. But first the Russians put out the eyes of Old Kinoos that he might never show the way again, and then they fought, where the waves beat white, with the people of Pastolik."Now the head-man of these Russians was Ivan. He it was, with his two thumbs, who drove out the eyes of Kinoos. He it was who fought his way through the white water, with two men left of all his men, and went away along the rim of the Great Fog Sea into the north. Kinoos was wise. He could see no more and was helpless as a child. So he fled away from the sea, up the great, strange Yukon, even to Nulato, and I fled with him."This was the deed my father did, Kinoos, an old man. But how did the young man, Negore?"What information in the story would best support the idea that Kinoos should be called Kinoos, the brave? (1 point)Select one:a. He entered many unknown villages seeking shelter.b. He raised a child on his own.c. He travelled across the Great Fog Sea.d.
