Answer:

[tex]n = -5[/tex]

Step-by-step explanation:

Given

[tex]Digit = 0.000025[/tex]

Required

Rewrite using scientific notation, then find n

[tex]Digit = 0.000025[/tex]

Express as fraction

[tex]Digit =\frac{25}{1000000}[/tex]

This can be splitted to

[tex]Digit = 25 * 10^{-6}[/tex]

The first number must be between 1 and 10; hence, 25 can be expressed as 2..5 * 10

[tex]Digit = 2.5 * 10* 10^{-6}[/tex]

Apply law of indices

[tex]Digit = 2.5 * 10^{1-6}[/tex]

[tex]Digit = 2.5 * 10^{-5}[/tex]

Comparing n, the given options

[tex]n = -5[/tex]

(a) The formula for the total time T, in minutes, needed to preheat the oven and bake a turkey weighing p pounds is T = 15 + 16p.

(b) The approximate time required to prepare a turkey weighing 14 pounds is 239 minutes.

We have,

(a)

To express the total time T, in minutes, needed to preheat the oven and then bake a turkey weighing p pounds, we can use the formula:

T = 15 + 16p

The first term, 15, represents the time needed to preheat the oven to 325 degrees (in minutes).

The second term, 16p, represents the recommended cooking time per pound for a turkey weighing p pounds (in minutes).

(b)

Using the formula T = 15 + 16p, we can find the approximate time required to prepare a turkey weighing 14 pounds:

T = 15 + 16 * 14

T = 15 + 224

T = 239

Therefore, the approximate time required to prepare a turkey weighing 14 pounds is 239 minutes.

Thus,

(a) The formula for the total time T, in minutes, needed to preheat the oven and bake a turkey weighing p pounds is T = 15 + 16p.

(b) The approximate time required to prepare a turkey weighing 14 pounds is 239 minutes.

Answer:

0.06546.

Step-by-step explanation:

Total number of tickets = 715

Good raffle tickets  (Prize) = 4

Number of tickets bought = 12

[tex]\text{Probability of winning}=\dfrac{\text{Number of tickets bought}}{\text{Total raffle tickets}}[/tex]

[tex]\text{Probability of winning}=\dfrac{12}{715}[/tex]

[tex]\text{Probability of not winning}=1-\dfrac{12}{715}=\dfrac{703}{715}[/tex]

Let x be event of the number of winning prizes.

Probability that you will win at least 1 of the raffles is

[tex]P(x\geq 1)=1-P(x=0)[/tex]

[tex]P(x\geq 1)=1-^{4}C_0\left(\dfrac{12}{715}\right)^0\left(\dfrac{703}{715}\right)^{4-0}[/tex]

[tex]P(x\geq 1)=1-\left(\dfrac{703}{715}\right)^{4}[/tex]

[tex]P(x\geq 1)=1-0.93454[/tex]

[tex]P(x\geq 1)=0.06546[/tex]

Therefore, the required probability is 0.06546.

Answer:

65%

Step-by-step explanation:

The formula for the grade of the ramp = Rise of the ramp/ horizontal distance of the ramp

Rise of the ramp = 52 feet

Horizontal distance = 80 feet

Grade of the ramp = 52 feet/80 feet

= 0.65

The grade of the ramp is 0.65

Rounding up to the nearest whole percent

Grade of the ramp = 0.65 × 100

= 65%

Therefore, the grade of the ramp to the nearest whole percent = 65%

Answer:1.33333333333 hamburgers every minute

Step-by-step explanation:40 burgers ÷ 30minutes = 1.333333 burgers every minute

A wheel with a 20 in diameter has a circumference of 2π*(20 in) = 40π in.

For every 40π in traveled, a wheel makes one complete revolution, or turns an angle of 2π rad.

We need to convert from in to mi: there are 12 in to 1 ft, and 5280 ft to 1 mi, and so there are 12*5280 = 63,360 in to 1 mi.

We also need to convert h to min: there are 60 min to 1 h.

So we have an angular speed of

(45 mi/h) * ((2π)/(40π) rad/in) * (63,360 in/mi) * (1/60 h/min) = 2376 rad/min

As mentioned before, there are 2π rad to 1 rev, so

(2376 rad/min) * (1/(2π) rev/rad) ≈ 378.152 rev/min

(where rev/min is equivalent to rpm)

Answer:

Domain: x ≥ 7

Range: y ≥ -1

Step-by-step explanation:

Domain is the set of x-values that can be inputted into function f(x).

Range is the set of y-values that can be outputted from function f(x).

We know that we can't take a square root of a negative and get a real number. The closest we can get is the square root of zero, no less.

What x-value renders the square root 0? x = 7 does, and we can't go less than that or we will get imaginary numbers. Therefore, the domain is x ≥ 7.

To find the range, we simply solve the rest of the function when x = 7, as we cannot go any lower.

y = 0 - 1

y = -1

Therefore, our range has to be y ≥ -1 because that would be the lowest y-value outputted from the lowest x-value.

Answer:

155

Step-by-step explanation:

∠QOR= 25

∠POQ = x

here sum of both angles is 180 ( by linear pair)

therefore,

∠QOR + ∠POQ =180

25 + x = 180

x=180-25

x=155

hence, ∠POQ= 155

Answer:

0.94 liters antifreeze is  drained out and replaced with water to get a concentration to 50 per cent of the solution.

Step-by-step explanation:

Total amount of the solution is 4.7 liters.

It contains 70 percent antifreeze = 70% * of 4.7 = 3.29 liters of antifreeze

It contains 30 percent water = 30% * of 4.7= 1.41 liters water

For the solution to have 50 % antifreeze it must contain

4.7 * 50%= 2.35 antifreeze.

We have 3.29 liters and we want to have 2.35 liters of antifreeze

Therefore we will (3.29-2.35 =)0.94 liters drained out and replace it with water to get a concentration to 50 per cent.

Answer:

$30

Step-by-step explanation:

The price of each chemistry class is $30.

Answer:

$134.71

Step-by-step explanation:

This is a simple interest question

A = P(1 + rt)

A = Amount after t months or years

P = Principal or amount saved

r = interest rate = 5.18% = 0.0518

t = time.in years = 18 months

= 1 year and 6 month

= 1.5 year

A = $125( 1 + 0.0518 × 1.5)

A = $125 ( 1 + 0.0777)

A = $125(1.0777)

A = $134.71

Step-by-step explanation:

A graph is formed using the height of students in Diego's math class.

It is provided that he arranges the students from shortest to tallest and measures the height in inches of each student in the class.

A distribution is known as to be skewed to the right, or positively skewed, when maximum of the data are collected on the left of the distribution and the graph has a longer tail towards the right.

For a positively skewed data: Mean > Median

A distribution is said to be skewed to the left, or negatively skewed, if maximum of the data are collected on the right of the distribution and the graph has a longer tail towards the left.

For a negatively skewed data: Mean < Median

A distribution is said to be symmetric, if maximum of the data are collected in the middle of the distribution and the graph has equal proportion of tails on both sides.

For a symmetric data: Mean = Median

Answer

81 tokens

Step-by-step explanation:

x+12-4=170

x+8=170

 -8   -8

x=162

     162/2=81 tokens

The number of tokens he had before he started playing the game is 81 tokens.

Given,

James is playing an arcade game with tokens.

In the first game, he hits the jackpot and doubles the number of tokens that he has.

In the second game, James wins 12 more tokens.

In his third and final game, he loses 4 tokens. James now has 170 tokens.

We need to find how many tokens did he have before he started playing the game.

Doubles = multiply by 2

x more than M = M + x

Loses x from M = M - x

We have,

Let the number of tokens he had initially be M.

First game:

Doubles the number of tokens

= 2M

Second game:

James wins 12 more tokens.

=  2M + 12

Third game:

Loses 4 tokens.

= 2M + 12 - 4

= 2M + 8

James now has 170 tokens

This means:

2M + 8 = 170

2M = 170 - 8

2M = 162

M = 162 / 2

M = 81

Thus the number of tokens he had before he started playing the game is 81 tokens.

The total number of seats in the auditorium are 2225.

Given is that an auditorium has 50 rows of seats. The first row has 20 seats, the second row has 21 seats, the third row has 22 seats.

We can write the sequence as -

20, 21, 22, 23, 24, .......,

It is a arithmetic sequence. We can write the total number of seats in the auditorium as the sum of the terms of the sequence. We can write -

S{n} = (50/2)(2 x 20 + 49 x 1)

S{n} = 25(40 + 49)

S{n} = 25 x 89

S{n} = 2225

Therefore, the total number of seats in the auditorium are 2225.
