A star is a swirling mass of dense gases powered by thermonuclear reactions. The great solar furnace transforms 7 million tons of mass into energy every second. How many tons of mass will be transformed into energy during the star's 10-billion-year lifetime. Hint: Find the number of seconds in 10 billion years.

Answers

Answer:

2.20752 x [tex]10^{24}[/tex]

Step-by-step explanation:

The first thing you have to do is to look for the number of seconds in one year. You have to multiply 365 days by 86,400 seconds.

365 days refer to the total number of days per year86,400 seconds refer to the number of seconds per day

Let's solve.

365 x 86,400 = 31,536,000 or 3.1536 x [tex]10^{7}[/tex]

Therefore, one year has 3.1536 x [tex]10^{7}[/tex] seconds.

Next, you have to know the number of seconds in 10 billion years.

(3.1536 x [tex]10^{7}[/tex]) x  (1.0 x [tex]10^{10}[/tex]) = 3.1536 x [tex]10^{17}[/tex]

The last step is to multiply the number of seconds in 10 billion years to 7 million tons of mass per second.

(3.1536 x [tex]10^{17}[/tex]) x 7,000,000 = 2.20752 x [tex]10^{24}[/tex]

Answers

Answer:

Percent of increase in weight = 33.33% Approx.

Step-by-step explanation:

Given:

Old weight = 60 pound

New weight = 80 pound

Find:

Percent of increase in weight

Computation:

Percent of increase in weight = [(New weight - old weight)/Old weight]100

Percent of increase in weight = [(80 - 60)/60]100

Percent of increase in weight = [(20)/60]100

Percent of increase in weight = 33.33% Approx.

An automobile manufacturer sold 30,000 new cars, one to each of 30,000 customers, in a certain year. The manufacturer was interested in investigating the proportion of the new cars that experienced a mechanical problem within the first 5,000 miles driven. a) A list of the names and addresses of all customers who bought the new cars is available. Each customer from a simple random sample of 1,000 customers who bought one of the new cars was asked whether they experienced any mechanical problems within the first 5,000 miles driven. 400 customers from the sample reported a problem. Of the 400 customers who reported a problem, 140 customers, or 32.5%, reported a problem specifically with the power door locks. Explain why 0.35 should not be used to estimate the population proportion of the 30,000 new cars sold that experienced a problem with the power door locks within the first 5,000 miles driven.

Answers

Answer:

The reason that 0.35 should not be used to estimate the population proportion of the 30,000 new cars sold that experienced a problem with the power door locks within the first 5,000 miles driven is that 0.35 does not represent the sample proportion.

The correct sample proportion is 0.14 (140/1,000) and not 0.35 (140/400).  It is this that can be used to estimate the population proportion and not 0.35.

Step-by-step explanation:

a) Data and Calculations:

New cars sold by the automobile manufacturer = 30,000

Number of customers that the 30,000 new cars were sold to = 30,000

Simple random sample = 1,000 customers

Number of customers from the SRS that reported a problem = 400

This is equal to 40% of the sample (400/1,000 * 100)

Proportion of customers who reported a problem (specifically) with the power door locks = 140/400 = 0.35

Proportion of customers out of the sample that reported specifically a problem with the power door locks = 140/1000 = 0.14.

Help 30 point question!

Answers

You're given 3 points (x, y) on the circle with equation

x ² + y ² + Dx + Ey + F = 0

and you have to use these known points on set up 3 equations involving D, E, and F.

For the point (3, -1), this means when x = 3, y = -1, so

3² + (-1)² + 3D - E + F = 0

→   3D + (-1)E + 1F = -10

The next point (-2, 4) gives

(-2)² + 4² - 2D + 4E + F = 0

→   (-2)D + 4E + 1F = -20

And from the last point (6, 8),

6² + 8² + 6D + 8E + F = 0

→   6D + 8E + 1F = -100

Armando has 3 blue shirts, 3 green shirts,

and 2 red shirts. He has 3 pairs of jeans

and 4 pairs of cargo pants. He is equally

likely to wear any of the shirts with any

pair of pants. What is the probability that

Armando will wear a green shirt with cargo pants?

Answers

Answer:

0.2143 = 21.43% probability that Armando will wear a green shirt with cargo pants.

Step-by-step explanation:

Probability:

A probability is the number of desired outcomes divided by the number of total outcomes.

Probability of independent events:

The probability of two independent events is the multiplication of their separate probabilities.

Green shirt:

3 green shirts, out of 3 + 3 + 2 = 8 shirts.

So 3/8 probability of green shirts.

Cargo pants:

4 cargo pants, our of 4 + 3 = 7.

So 4/7 probability of cargo shirts.

Green shirt and cargo pants:

[tex]p = \frac{3}{8} \times {4}{7} = \frac{12}{56} = \frac{3}{14} = 0.2143[/tex]

0.2143 = 21.43% probability that Armando will wear a green shirt with cargo pants.

Gabe​ Amodeo, a nuclear​ physicist, needs 90 liters of a ​50% acid solution. He currently has a 30% solution and a 60% solution. How many liters of each does he need to make the needed 90 liters of ​50% acid​ solution?

Answers

Answer:

You need two equations: one for solution amounts and one for alcohol amounts.

Step-by-step explanation:

90 = X + Y

45 = (0.6)/X + (0.3)Y

Here X = amount of 60 % solution and Y = amount of 30 percent solution. Note that percentages have been converted to decimal amounts in the second equation.

From here you have to solve two equations with two unknowns. Easiest to solve first equation for X = 90 - Y, then substitute into second equation. this get you one equation in one unknown. Solving you you will get

X = 30 liters and Y = 60 liters.

The Farmers Market sells apples by the bushel, and each bushel of apples weighs 42 lbs. A bushel of large apples contains 84 apples. If a bushel of small apples contains twice as many apples is a bushel of large apoles, how many small apples are in 1 lb of apples?​

Answers

Answer:    4 apples in 1 lb

Step-by-step explanation:

Since there are twice as many apples as large apples, you would multiply

2 x 84 = 168

To find the apples per pound we want to divide the total number of apples, which is 168 by the weight of the bushel which is 42 lbs.

168/42=4

Therefore, there is 4 apples in 1 lb.

here we have hypoteaus and base

so by using pythagoreaus theorem

p^2 = 13^2 - 12^2

p^2 = 169 - 144

p^2 = 25

p = root under 25

p = 5

Answer:

5 cm

Step-by-step explanation:

A^2+B^2=C^2

12^2+B^2=13^2

144+B^2=169 (You have to subtract 144 from both sides to get B^2 by its self)

-144       = -144

B^2= 25 (To get rid of the square you have to find the square root)

Answers

Answer:

1) $68.40

2)456 tickets

Step-by-step explanation:

1)

They need to raise $8,250.

They have already raised $3,120.

The amount they have still to raise is $8,250-$3,120=$5,130.

There are 75 band members, so the amount yet to raise per member is $5,130/75=$68.40.

2)

The businesses give $0.50 for every $1 in ticket sales, ie. they pay an extra 50% of the total.

Let number of tickets sold=x

Let money made from ticket sales = 7.5x

The total amount of money made is therefore 1.5(7.5x)=11.25x

The minimum amount of tickets to hit $5,130:

$5,130=11.25x

x=456

3. What variable represents the output of this function?

4. Write the inverse of the function you wrote.

5. What variable represents the input of the inverse function?

6. What represents the output of the inverse function?​

Answers

Answer:

1. f(N) = C ,where C = N - 7

2. The input of the function is x = N

3. The output of the function = y = C = N -7

4. F(C) = N where N = C - 7

5. Input of the inverse function = C

6. Output of the inverse function = N = C - 7

Step-by-step explanation:

Let Noah's cousin age = C

and  Noah's age = N

As given ,Noah's cousin is exactly 7 years younger than Noah.

⇒ C = N - 7

a.)

As we know that , A function is a maping of x to y such that f(x) = y

Let x = N , y = C

So, f( x) = y

⇒f(N) = C ,where C = N - 7

b.)

The input of the function is x = N

c.)

The output of the function = y = C = N -7

d.)

A inverse function is a mapping of y to x

i.e change the variable ,

As we have C = N - 7

It becomes

N = C - 7

So the inverse function becomes

F(C) = N where N = C - 7

e.)

Input of the inverse function = C

f.)

Output of the inverse function = N = C - 7
