A point has zero dimension. True or False?

Answers

Answer 1

Answer:

Answer:

True

Step-by-step explanation:

A point is zero-dimensional with respect to the covering dimension because every open cover of the space has a refinement consisting of a single open set.

Sorry! OK. I'll make this quick. Formula: A= A+B+C+D
A= 134 cm2
B= 170 cm2
C= 202cm2
D= 238 cm2
So, just add them altogether.
A= 744 cm (But I don't know what the exponent would be. Sorry!) I think that is how it would be. Its been a while since of done Area, though. Sorry about not knowing the exponent. And sorry if this isn't acurate.

Answer:

Area of the rectangle: 24 cm²
Area of the circle: 380.13 cm²
Area of between the circle and the rectangle: 356.13 cm²

Explanation:

The question describes a rectangle of dimensions 4 cm × 6 cm inscribed in a circle with radius 11 cm.

You can find:

The area of the rectangle
The area of the circle
The area between the rectangle and the circle.

1. Area of the rectangle:

$Area=length* width=4cm* 6cm=24cm^2$

2. Area of the circle:

$Area=\pi* radius^2=\pi * (11cm)^2\approx 380.13cm^2$

3. Area between the rectangle of the circle:

This is the area of the circle that does not belong to (or is outside of) the area of the rectangle.

$Area=\text{area of the circle - area of the rectangle}\n \n Area=380.13cm^2-24cm^2=356.13cm^2$

Marcia says she can use rounding to find the exact product of 6x75. She says that since 75 is halfway between 7 tens and 8 tens the exact product of 6x75 must be halfway between 6x70 and 6x80 is she correct

Answers

Marcia is correct if she says she can use rounding to find the exact product of 6x75; the exact product of 6x75 must be halfway between 6x70 and 6x80.

What is an arithmetic operation?

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.

It is given that:

Marcia says she can use rounding to find the exact product of 6x75.

From the data:

Find the product of 6 and 75:

= 6x75

= 450

Find the product of 6 and 70:

= 6x70

= 420

Find the product of 6 and 80:

= 6x80

= 480

= 420 + 30

=450

= 450 + 30

= 480

The expression can be defined as the combination of constants and variables with mathematical operators.

Thus, Marcia is correct if she says she can use rounding to find the exact product of 6x75; the exact product of 6x75 must be halfway between 6x70 and 6x80.

Yes because 6x75=450
6x70=420
6x80=480

So 420+30=450
450+30=480
