A scale drawing of a soccer field is 6 inches long. The actual soccer field is 300 feet long. Which of the following represents
2 answers:
Answer:
<em>1in : 50ft </em>
<em>6in : 300ft</em>
Step-by-step explanation:
<u>Scaling</u>
Objects can be represented in a reduced or augmented size by using scaling which is basically multiplying or dividing by a constant factor. For example, we can use scaling when representing geographic locations or dimensions on a map.
The soccer field is represented by a drawing that is 6 inches long, and the actual soccer field is 300 feet long.
To calculate the scale factor, we divide the actual dimension by the scaled dimension:
Dividing:
factor = 50 ft/in
This means each inch of the drawing represents 50 ft of the actual field, thus the scale factor is 1 in:50 ft.
If we hadn't divided, the scale factor would be 6 in:300 ft, thus there are two correct choices:
1in : 50ft
6in : 300ft

Answer:
She consumes 30 blue ray disk and 60 DVD respectively.
Step-by-step explanation:
Consider the provided information.
Calculate marginal utility of good
Differentiate with respect of x and y.
Her consumption of Blu-ray disks (X) with a price of $40 and Y is her consumption of DVDs with a price of $10.
The ratio of marginal utility of good x to y is equal to the price ratio:
Substitute the respective values.
She has $1800 with which to spend on the two goods.
Her consumption of Blu-ray disks (X) with a price of $40 and Y is her consumption of DVDs with a price of $10. She has $1800 with which to spend on the two goods.
Therefore,
Substitute the value of y in above equation.
Thus,
She consumes 30 blue ray disk and 60 DVD respectively.
Answer:
12
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
Here [ a, b ] = [ 3, 6 ] , then
f(b) = f(6) = 6² + 3(6) + 2 = 36 + 18 + 2 = 56
f(a) = f(3) = 3² + 3(3) + 2 = 9 + 9 + 2 = 20 , then
average rate of change = =
= 12
