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)

Answer:
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

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.

Find the arc length of the partial circle.

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.

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.
