Write the following expression using symbolic language.
1) Five less than the product of seven and a number x
2) The difference of nine times a number y and eighteen
3) Half a number n increased by four times the number
4) Twice the sum of a number w cubed and twenty-three

Answers

Answer:

1) 7x - 5 2) 9y - 18 3) 0.5n + 4n 4) 2(w³+23) Step-by-step explanation:

The product of seven and a number x: 7·x = 7x

Five less than the product of seven and a number x:

7x - 5

nine times a number y: 9·y = 9y

The difference of nine times a number y and eighteen:

9y - 18

half a number n: 0.5n

four times the number: 4·n = 4n

Half a number n increased by four times the number:

0.5n + 4n

a number w cubed: w³

the sum of a number w cubed and twenty-three: w³+23

Twice the sum of a number w cubed and twenty-three:

2(w³+23)

If the sequence 4, 8, 12, 16 continues, what will be the 7th
term?

Answers

Answer:

Step-by-step explanation:

In order to find the seventh term in this arithmetic function, you need to find its function; in order to do this, you must first identify the common difference by finding the difference between two consecutive terms:

16 - 12 = 4; the common difference is 4

Now, you need to find the 0th term, which is the 1st term minus the common difference:

4 - 4 = 0

At this point, you can write out the function (where f(n) = [0th term] + [common difference]n:

f(n) = 4n

Finally, you can plug 7 into this function:

f(n) = 4(7)

f(n) = 28, so the 7th term is 28

Answers

Answer:

Yes, the amount of sugar you need proportional to the amount of lemonade mix you use.

Step-by-step explanation:

You are making lemonade. The amount of sugar you need depends on the amount of lemonade mix you use. Cups of sugar

1/3

Packets of lemonade mix

Is the amount of sugar you need proportional to the amount of lemonade mix you use?

Cups of sugar ∝ Number of packets

C ∝ N

C = k/N

k = C/N

a) For

1/3 cups of sugar and 1 packet of Lemonade mix

1/3 ∝ 1

1/3 = 1k

k = 1/3/1

k = 1/3

b) For

1 cups of sugar and 3 packets of Lemonade mix

1 ∝ 3

1 = 3k

k = 1/3

c) For

3 cups of sugar and 9 packets of Lemonade mix

3 ∝ 9

3= 9k

k = 3/9

k = 1/3

Therefore, Yes, the amount of sugar you need proportional to the amount of lemonade mix you use. This is because the value is k is the same

Answers

Answer:

4/9

Step-by-step explanation:

At t = 0 ; volume = 270

At t = 1.5 ; volume = 80

y = P(1 - r)^t

y =ab^x (exponential)

a = initial amout at t = 0

y = final amount

t = 1.5

80 = 270b^t

80/270 = b^t

8/27 = b^1.5

8/27 = b^3/2

b^3/2*2/3 = (8/27)^2/3

Cube root of 8/27 = 2/3

Square of 2/3 = (2/3)^2 = 4/9

Find the interest
earned:
$26,000 for 36 months
at 7.5% annual
compound interest

Answers

Answer:

Interest = $6,300 (Approx.)

Step-by-step explanation:

Given:

Amount deposit (P) = $26,000

Number of month = 36 month

Number of year (n) = 36 / 12 = 3 year

Rate of interest (r) = 7.5% = 0.075

Find:

Interest earned

Computation:

Interest = p[(1+r)ⁿ-1]

Interest = 26,000[(1+0.075)³-1]

Interest = 26,000[(1.075)³-1]

Interest = 6,299.71

Interest = $6,300 (Approx.)

The total cost of a pair of shoes and a hoodie is $150 the hoodie cost $100 more than the pair of shoes how much does each item cost?

Answers

x + y = 150

x = y + 100

2y + 100 = 150

2y = 50

y = 25

shoes are 25 hoodie is 125

Answer:

shoes = $25

hoodie = $125

Step-by-step explanation:

total cost = $150

hoodie = x + 100

shoes = x

x + x + 100 = 150

2x = 150 - 100

x = 50/2

x = 25

shoes = $25

hoodie = $125

add them up and u get the price of the shoe 125+25= $150

Find the volume of a right circular cone that has a height of 2.7 ft and a base with a diameter of 14.4 ft. Round your answer to the nearest tenth of a cubic foot.

Answers

Answer:

20.4 cubic feet

Step-by-step explanation:

formula for the volume of a cone is (r^2xhxpi)/3

so, r= 14.4/2

(7.2x2.7xpi)/3

The volume of a right circular cone is 146.49 cubic foot.

What is the volume of a right circular cone?

The Volume of Right Circular Cone formula is defined as The volume of a cone is one-third of the product of the area of the base and the height of the cone.

The volume of a right circular cone is given by;

[tex]\rm Volume=\dfrac{1}{3}\pi r^h\\\\r = radius, \ h = height\\[/tex]

The volume of a right circular cone that has a height of 2.7 ft and a base with a diameter of 14.4 ft.

The radius of the cone is;

[tex]\rm Radius=\dfrac{diameter}{2}\\\\ Radius=\dfrac{14.4}{2}\\\\ Radius=7.2[/tex]

The volume of a right circular cone is;

[tex]\rm Volume=\dfrac{1}{3}\pi r^h\\\\ Volume=\dfrac{1}{3}\times 3.14 \times (7.2)^2\times 2.7\\\\Volume=146.49[/tex]

Hence, the volume of a right circular cone is 146.49 cubic foot.

An Indian anthropologist, Chandra Thapar, made a study of foreign cultures which had customs similar to those of his native land. One culture in particular fascinated him because it reveres one animal as sacred, much as the people in India revere the cow. The tribe Dr. Thapar studied is called the Asu and is found on the North American continent north of the Tarahumara of Mexico. Though it seems to be a highly developed society of its type, it has an overwhelming preoccupation with the care and feeding of the rac - an animal much like a bull in size, strength and temperament. In the Asu tribe, it is almost a social obligation to own at least one if not more racs. Anyone not possessing at least one is held in low esteem by the community because he is too poor to maintain one of the beasts properly. Some members of the tribe, to display their wealth and prestige, even own herds of racs. Unfortunately the rac breed is not very healthy and usually does not live more than five to seven years. Each family invests large sums of money each year to keep its rac healthy and shod, for it has a tendency to throw its shoes often. There are rac specialists in each community, perhaps more than one if the community is particularly wealthy. These specialists, however due to the long period of ritual training they must undergo and to the difficulty of obtaining the right selection of charms to treat the rac, demand costly offerings whenever a tribesman must treat his ailing rac. At the age of sixteen in many Asu communities, many youths undergo a puberty rite in which the rac figures prominently. The youth must petition a high priest in a grand temple. He is then initiated into the ceremonies that surround the care of the rac and is permitted to keep a rac. Although the rac may be used as a beast of burden, it has many habits which would be considered by other cultures as detrimental to the life of the society. In the first place the rac breed is increasing at a very rapid rate and the Asu tribesmen have given no thought to curbinanswer this question pleaseeee 1)What is the Theme (An underlying message about life or human nature that the writer wants the reader to understand) of this work?
