Which expression shows four times eight to the fifth?

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.

Answer:

x=149

Step-by-step explanation:

pythagoras theorem dictates that a squared +b squared= c squared

in this case, c=x

51*51+140*140=x*x

2601+19600=x*x

22201=x*x

x=149

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

Answer:2 times 5 equals 10

Step-by-step explanation:

"The factors of 10 are 1, 2, 5, and 10. You can also look at this the other way around: if you can multiply two whole numbers to create a third number, those two numbers are factors of the third. 2 x 5 = 10, so 2 and 5 are factors of 10." From ww.infoplease.com great resource

The required factor of 10 in 10 of the third power is 3.

A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor.

Here,

10 of the third power = 10³
10³ = 10×10×10
The expression 10×10×10 has 3, 10's

Thus, the required factor of 10 in 10 of the third power is 3.

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
