A land bridge from Asia to the Americas was made possible by which of the following?

A) archaeologists

B) the development of stone tools

C) last Ice Age

D) prehistoric people

Answers

Answer:

C, Last Ice Age

Step-by-step explanation:

A land bridge wouldn't be developed by humans. The only reasonable explanation would be the last Ice Age

A land bridge from Asia to the Americas was made possible by the last Ice Age.  So, the correct answer is C.

What is Land Bridge?

A land bridge is an isthmus or wider land connection between otherwise separate areas, over which animals and plants are able to cross and colonize new lands.

A land bridge from Asia to the Americas was made possible by the last Ice Age.

During the last Ice Age, much of the Earth's water was locked up in glaciers, causing sea levels to drop and exposing a land bridge between Asia and North America.

This allowed prehistoric people to migrate from Asia to the Americas, a journey that would not have been possible without the land bridge created by the last Ice Age.

Hence, A land bridge from Asia to the Americas was made possible by the last Ice Age.  So, the correct answer is C.

Answers

Answer:

26

Step-by-step explanation:

The mean absolute deviation of the data is 11.

The mean absolute deviation (MAD) of a data set is the average distance between each data value and the mean.

To find the mean absolute deviation of the data, start by finding the mean of the data set. Find the sum of the data values, and divide the sum by the number of data values.

Given: The data below show the weights, in pounds, of a group of professional football players.

325, 310, 289, 288, 285, 285, 285, 280, 280, 273

The mean of the data set is 290 pounds.

How to find the mean absolute deviation of the data

set, to the nearest whole number?

The average absolute deviation is

[(325-290)+(310-290)+|(289-290)|+|(288-290)|+3|(280-290)|+21(280-290)|+|(273-290)|]/10

=> (35+20+1+2+5+5+5+10+10+17)/10

325 adults and 612 children

A total of 937 people attended the play.  Admission was $2.00 for adults and $0.75  for students. The total ticket sales  amounted to $1,109. How many students  and adults attended the school play?  First complete the equations below, where A  stands for Adults and S stands for Students.

[325]A + [612]S = 1,109; A + S = [2.75]

325 (amount of adults)  x 2 (2 is the amount of money for each adult ticket)

= $650

937 (amount of people total in the play) - 325 (adults)

= 612 (kids)

612 x 0.75 (amount for each child)

= $459

$459 + 650 = $1109

325 + 612 = 937

Find the arc length of the partial circle.
Either enter an exact answer in terms of t or use 3.14 for it and enter your answer as a decimal.

Answers

Answer:

9.42 Units

Step-by-step explanation:

Either enter an exact answer in terms of pi or us 3.14 for pi and enter your answer as a decimal.

The arc length of a partial circle whose radius is 8 and measure of the central angle is 90 degrees is 12.

To find the arc length of a partial circle, we can use the formula:

Arc Length (L) = θ × r,

where L is the arc length, θ is the central angle in radians (or degrees), and r is the radius of the circle.

In this case, the radius (r) is given as 8 units, and the measure of the central angle (θ) is given as 90 degrees. However, we need to convert the central angle from degrees to radians before plugging it into the formula, as trigonometric functions work with radians.

To convert degrees to radians, we use the conversion factor: π radians = 180 degrees.

θ (in radians) = 90 degrees × (π radians / 180 degrees) ≈ 1.57 radians.

Now, we can calculate the arc length:

Arc Length (L) = 1.57 radians × 8 units ≈ 12.

Which expression is equivalent to 36a minus 27?
9 (4a minus 3)
3 (18a minus 9)
9 (4a minus 27)
3 (12a minus 6)

Answers

Answer:

It's the first expression

Step-by-step explanation:

9 (4a minus 3)

(9x4a)-(9x3)

36a minus 27

The correct expression equivalent to 36a minus 27 is 9(4a minus 3)

What is an expression?

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given that, an expression is 36a minus 27, we need to find an expression equivalent to the given expression,

So, converting the expression into mathematical expression,

36a minus 27

= 36a-27

HCF of 36 and 27 is 9, so taking 9 common,

Therefore,

36a-27 = 9(4a-9)

We can write 9(4a-9) in statement,

9(4a-9) = 9(4a minus 3)

Hence, the correct expression equivalent to 36a minus 27 is 9(4a minus 3)
