According to modern science. Earth is about 4.5 billion years old and written human history extends back about 10,000 years. Suppose you represent the entire history of Earth by 12 hours on a clock, with the birth of Earth at the stroke of midnight and today at the stroke of noon. How long before noon does written human history begin?

Answer:

a) 376.66

b) Option 2: No, the result from part (a) could not be the actual number of adults who said that rising gas prices are "quite annoying" because a count of people must result in a whole.

c) 377

d) 40.77%

Step-by-step explanation:

a) 37% of 1018 is;

37/100 × 1018 = 376.66

b) Thus, the result in a above is not a whole number. Thus;

No, the result from part (a) could not be the actual number of adults who said that rising gas prices are "quite annoying" because a count of people must result in a whole.

c) from a above a, we got a value of 376.66.

Now the actual number would be preferably an integer. Thus, actual number is approximately 377.

d) percentage of respondents said that cellular phones are not at all harmful = 415/1018 × 100% = 40.77%

Answer:

x = -12

Step-by-step explanation:

multiply all terms by 3 to get whole numbers

->21+2x=-3

subtract 21 both sides to isolate the variable

->2x=-24

divide by 2 both sides to simplify

->x=-12

Answer:

Total Probability = 1 / 221

Step-by-step explanation:

Total number of cards = 52

Total number of kings = 4

Probability (first card is a king) = 4 / 52

Probability (Second card is a king) without replacement = [4-1] / [52-1]

Probability (Second card is a king) without replacement = 3 / 51

Total Probability = [Probability (first card is a king)][Probability (Second card is a king) without replacement]

Total Probability = [4/52][3/51]

Total Probability = 12 / 2652

Total Probability = 1 / 221

[tex] slope (m) = 6 [/tex]

Step-by-step explanation:

To get the slope of the line of the given table of values, all we need is just 2 coordinate pairs from the table. We can pick any two.

Let's use, (-1, 0), and (0, 6).

Apply the formula, [tex] \frac{y_2 - y_1}{x_2 - x_1} [/tex], where,

[tex] (-1, 0) = (x_1, y_1) [/tex]

[tex] (0, 6) = (x_2, y_2) [/tex]

Thus:

[tex] m = \frac{6 - 0}{0 - (-1)} [/tex]

[tex] m = \frac{6}{1} [/tex]

[tex] slope (m) = 6 [/tex]

Answer:

5.40

Step-by-step explanation:

i think that's it because

if u take 150 - the one cake it will equal = 135

then u divide 135 by the 25 pies it will equal 5.40

150-15= 135

135÷ 25= 5.60

Step-by-step explanation:

LHS = (tan β + Sec β)(1 - sin β)

= ((sin β / cos β) + (1/cos β))(1-sin β)

= ((1+ sin β)*(1- sin β))/cos β

= (1 - sin^2 β) / cos β

= cos^2 β / cos β

= cos β

= RHS

Hence proved

Answer:

Three plus six: 3 * 6

When we multiply x*y, we are summing x times the same number: y ory times the same number.(x)

In our case, we are summing three times six, so: 6 + 6 + 6 = 18

We could also say we are summing six times three: 3 + 3 + 3 + 3 + 3 + 3 = 18

Nowwe can say that 6 * 3 = 18

Alternate interior angles

Answer:

29900 ft

Step-by-step explanation:

just plug in 18 for x

A function assigns the values. The predicted height of the airplane after 18 minutes of takeoff is 29,864 ft.

A function assigns the value of each element of one set to the other specific element of another set.

The measure of the height of an airplane at a certain time is given by the function,

[tex]y = \dfrac{29,864 }{1+9.381 e^{-0.9948x}}[/tex]

where x is the time in minutes and y is the height of the airplane.

Now, the height of the plane after 18 minutes post takeoff can be calculated by substituting the value of time, x as 18 in the function.

[tex]y = \dfrac{29,864 }{1+9.381 e^{-0.9948x}}\\\\y = \dfrac{29,864 }{1+9.381 e^{-0.9948 \times 18}}\\\\y = \dfrac{29,864 }{1+9.381 e^{-7.9064}}[/tex]

[tex]y = \dfrac{29,864 }{1+9.381 e^{-7.9064}}\\\\y = \dfrac{29,864 }{1+(9.381 \times 1.6724 \times 10^8)}\\\\y = \dfrac{29,864 }{1+(1.5689 \times 10^8)}\\\\y = \dfrac{29,864 }{1.000000157}[/tex]

y = 29864 ft

Hence, the predicted height of the airplane after 18 minutes of takeoff is 29,864 ft.
