Answers
30 inches would be longer because 2 feet is equal to 24 inches. 30 is larger than 24.
2 feet = 24 inches
30 inches is longer

60x-3x to the second power divided by 3x
Answers
example 4/2=2/2 times 2/1=1 times 2/1
then we undistribute the factor
we want a factor of 3x to make a one
60x=3x times 20
-3x^2=3x tiimes -x
use undistributive property which is
ab+ac=a(b+c)
so
60x-3x=3x(20)+3x(-x)=3x(20-x)
so now we have
[3x(20-x)]/3x=(3x/3x) times (20-x)/1=1 times 20-x=20-x
answer is 20-x

Answer: 1.2
Why? Here:
3.6 is also known as 36/100
So, 36/100 ÷ 3/1
36/100 x 1/3 ( transposing because of divide)
36 comes in 3 table so, 36÷3 is 12
12/100 x 1
12/100 also known as 1.2

The answers for both the parts are as (a) the rate of proofreading is 7.5 pages per hour and (b) The payment received for each page is $2,.67.
What is Unitary method ?
In order to solve a problem for two different values of a quantity, its unit value is first derived. This method is known as unitary method.
Given that,
The pages proofread in 2 hours is 15.
The total amount received is $40.
(a) The proofreading rate can be known by dividing the total pages by total time as below,
Rate of proofreading = 15/2 = 7.5 pages per hour.
(b) As per the question the unitary method can be applied to obtain the payment for one page as follows,
Payment for proofreading 15 pages = 40
Thus, payment for proofreading one page is 40/15 = 2.67.
Hence, the proofreadingrate is 7.5 pages per hour and the average payment for each page is $2.67 respectively.

because 15 (number of pages) divided by 2 (number of hours) is 7.5.
B. $2.67
Because $40 divided by 15 (the number of pages) is $2.67

Answer:
Option D is the correct answer.
Step-by-step explanation:
Refer the figure given below
Area of isosceles trapezoid = Area of 2 triangles + Area of rectangle.
We have
a = 16, b = 24 and h = 10
Substituting
Option D is the correct answer.
=(16+24)×10÷2
= 200 ft2
