A circle is dilated by a scale factor of 1.5 to create a new circle. The area of the new circle is 1.5 times the area of the original circle.
True or false??
Answers
Given:
The given statement is "A circle is dilated by a scale factor of 1.5 to create a new circle. The area of the new circle is 1.5 times the area of the original circle."
To find:
Whether the given statement in true or false.
Solution:
Area of circle is
[tex]A=\pi r^2[/tex]
Where, r is the radius of the circle.
Let [tex]r_1[/tex] be the radius of the original circle. So, the area of the circle is
[tex]A_1=\pi (r_1)^2[/tex]
The circle is dilated by a scale factor of 1.5 to create a new circle. So, the radius of the new circle is:
[tex]r_2=1.5r_1[/tex]
The area of the new circle is
[tex]A_2=\pi (r_2)^2[/tex]
[tex]A_2=\pi (1.5r_1)^2[/tex]
[tex]A_2=2.25\pi (r_1)^2[/tex]
[tex]A_2=2.25A_1[/tex]
The area of the new circle is 2.25 times the area of the original circle.
Therefore, the given statement is false.

Bob wants to order some books from an online bookstore. Each book costs 16.50 and shipping for the entire order is a flat rate of 25.03. Bob can spend no more than 78.00
Answers
Answer:
x ≤ 3.210
Bib can buy no more Than 3 books
Step-by-step explanation:
Given that:
Cost per book = 16.50
Total shipping = 25.03
Total budgeted amount = 78
The number of books, x that can be ordered can be represented by the inequality :
16.50x + 25.03 ≤ 78
16.50x ≤ 78 - 25.03
16.50x ≤ 52.97
x ≤ 52.97 / 16.50
x ≤ 3.210

Answers
Answer:
x = 7/10; y = 21/5
Step-by-step explanation:
y = 6x
4x + y = 7
Since the first equation is already solved for y, we can easily use the substitution method. We substitute 6x for y in the second equation and solve for x.
4x + y = 7
4x + 6x = 7
10x = 7
x = 7/10
Now we use the first equation and substitute 7/10 for x and solve for y.
y = 6x
y = 6 * 7/10
y = 42/10
y = 21/5
Answer: x = 7/10; y = 21/5

8 18
To find:
The slope of the line that described by the data in the table.
Solution:
Consider any two points from the given table.
Let the two points are (0,8) and (4,13). So, the slope of the line is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{13-8}{4-0}[/tex]
[tex]m=\dfrac{5}{4}[/tex]
[tex]m=1.25[/tex]
Therefore, the slope of the line described by the data in the table is 1.25.
