In the EXPLORE online library, the ratio of the number of novels to that of dictionaries is 2:3 and the total number of novels is 624. If Joe buys more novels and the ratio becomes 7:3, then how many novels have been bought in total?

Answers

Answer 1

Using a system of equations, it is found that 1530 more novels have been bought in total.

For the system, we have that:

x is the number of novels.y is the number of dictionaries.

The ratio of the number of novels to that of dictionaries is 2:3, hence:

[tex]\frac{x}{y} = \frac{2}{3}[/tex]

[tex]3x = 2y[/tex]

[tex]y = \frac{3x}{2}[/tex]

Total number of novels is 624, hence:

[tex]x = 624[/tex]

[tex]y = \frac{3}{2} \times 624 = 936[/tex]

Buys z more novels, and the ratio becomes [tex]\frac{7}{3}[/tex], hence:

[tex]\frac{624 + z}{923} = \frac{7}{3}[/tex]

[tex]1872 + 3z = 6461[/tex]

[tex]z = \frac{6461 - 1872}{3}[/tex]

[tex]z = 1530[/tex]

1530 more novels have been bought in total.

Identify the initial amount a and the rate of growth r (as a percent) of the exponential function f(t) = 1500(1.074)t. Evaluate the
function when t=5. Round your answer to the nearest tenth.
A=
R=%
When t=5, f(5)=

Answers

The initial amount is the first number = 1500

Rate of growth is inside the parentheses and is added to 1, the rate of growth is 7.4%

Replace t with 5 and solve

1500(1.074) ^5 = $2143.45

Answer:

The growth rate is 7.4% and the initial amount is 1500. The answer when t=5 is 2143.45.

Step-by-step explanation:

Assuming this is actually supposed to be written as 1500*(1.074)^t, then this equation follows the standard growth form y = A(1+r)^t where A represents the initial amount, r represents the rate as a decimal, and t represents time. This means that 1500 (A) would be the initial amount, and if you subtract 1 from what's inside the paratheses, you will get the r rate as a decimal. To get this as a percent, simply multiply it by 100, so you will get 7.4% as your growth rate.

To find what the answer would be when t = 5, just plug in 5 for the value of t in the equation.

f(5) = 1500*(1.074^5)

f(5) = 1500*(1.42896)

f(5) = 2143.45

Show your work.

Answers

Answer:

25 free throws on Friday.

Step-by-step explanation:

On Monday  made 20 free throws

On Friday made 25%  more free throws on Friday than Monday

On Friday made 20 free throws + 25% of Monday free throws

On Friday = Monday throws + 25% × Monday throws

On Friday       = 20 + (.25 × 20)

On Friday        = 20 + 5

Please answer me ASAP I need an answer.

Answers

Answer:

P = 15.95N - 550

Step-by-step explanation:

The profit is the difference between the revenue and the total cost:

P = R - C

Substitute values:

P = 31.90N - (550 + 15.95N)P = 31.90N - 15.95N - 550P = 15.95N - 550

The difference between cost and revenue is profit

P=R-CP=31.90N-(15.95N+550)P=31.90N-15.95N-550P=15.95N-550

Answers

Answer:

So the answer is... Hold on... Ok i did my research and the answer is........

Step-by-step explanation:

1. Economic

The Industrial Revolution stimulated the hunt for colonies. First, colonies provided raw

materials. Second, colonies served as a market for surplus manufactured goods.

2. Political

Every country wanted national hegemony – that is, to be the No. 1 imperialist country in the

world. To achieve this, they wanted to control as much of the world as

possible. The nation’s greatness is measured by the quality and quantity

of its colonies. Folks wanted to plant the flag in as many places as

possible. Every country wanted recognition as a world power. They

wanted to improve their reputation among other European countries.

They wanted to increase their political power and prestige. Every country

was in competition with its rivals. You took territory – simply to prevent

your rival from getting it!

3. Military

Every imperialist country was worried about its own national security: The competition

among imperialist powers was vicious. One had to protect one’s own

country and its colonies. Every country wanted to gain military

advantage over its rivals. A colony could serve as a fueling station for

the Navy. A ship could stop and load up on supplies. Some spots in the

world, especially waterways, were strategically important. The Navy

was paramount: It must have freedom to travel to and from the

colonies.

4. Cultural

Social Darwinism was the prevailing belief in Europe. It explained why some countries were

rich and some were poor. People compete for survival. The strong survive.

The rich were naturally superior. The weak were unfit. Poverty was a sign of

being unfit. The poor were naturally inferior. The European colonizers were

the Superior Races. The African and Asian colonized were Inferior Races. The

Europeans regarded themselves as racially and culturally superior to the people

of Africa and Asia. Humanitarians argued that it was Europe’s noble duty to

uplift and enlighten the backward peoples. Belief in Anglo-Saxon superiority

was prevalent.

5. Religious

The “missionary impulse”: Christianity is superior to all other religions. We must

spread Christianity to Asia and Africa. Religion encouraged imperialism. People

felt they needed to acquire territory in order to Christianize people. A serious

moral issue – Christianity is in direct conflict with Social Darwinism. Under

Christianity, all people are equal in God’s eyes. Under Social Darwinism, the

Europeans are superior and the Africans and Asians are inferior. There was also a

certain element of hypocrisy: While the Europeans spoke of uplifting people, they

were actually motivated by profit and greed.

Solve for y: 3^3 + 14 y- (25y - 13) = y + 7y - 9y

Answers

Answer:

y = 4

Step-by-step explanation:

3^3 + 14y - (25y - 13) = y + 7y - 9y

Exponents first.

27 + 14y - (25y - 13) = y + 7y - 9y

Distribute the negative sign from the parenthesis.

27 + 14y - 25y + 13 = y + 7y - 9y

Common terms.

27 + 13 = 40

14y - 25y = -11y

y + 7y - 9y = -y

40 - 11y = -y

Add 11 to both sides.

40 = 10y

Divide both sides by 10.

4 = y

Rearrange.

y = 4.

Dan bought a truck for $29,800. The value of the truck depreciated at a constant rate per year. The table shows the value of the truck after the first and second years: Year 1 2 Value (in dollars) 26,522 23,604.58 Which function best represents the value of the truck after t years? f(t) = 29,800(0.89)t f(t) = 26,522(0.89)t f(t) = 29,800(0.11)t f(t) = 26,522(0.11)t

Answers

Answer:

A) f(t) = 29,800(0.89)^t

Step-by-step explanation:The truck value decreases by 11% each year.

The present value of the truck was $29,800.

29,800 x 0.11 = 3,728 dollars lost from value.

29,800 - 3,728 = 26,522, the value of the truck after one year.

26,522 x 0.11 = 2,917.42 cash lost from value.

26,522 - 3,728 = 23,604.58, the value of the truck after two years.

Therefore, the answer is A) f(t) = 29,800(0.89)^t.

Step-by-step explanation:

Given the quadratic function, g(x) = x²- 5x + 8:

In order to evaluate and determine the output value given g(8), substitute the input value into the function:

g(x) = x²- 5x + 8

g(8) = (8)²- 5(8) + 8

g(8) = 64 - 40 + 8

g(8) = 32
