How do I prove that a quadrilateral is a rectangle?
maw [93]
I think you want to prove that a rectangle is a quadrilateral. You can prove this with definitions. The definition of a quadrilateral is that it is a shape with four sides. Since a rectangle has four sides, that proves that a rectangle is a quadrilateral.

Lisa completed the table to describe the product of a mystery one - digit factor and factor and each numbers
deff fn [24]

Answer: part A is 0, 2, 4, 6, 8 and part B is Because the products all are even, the mystery factor must also be an even number. We have selected all of the even one-digit numbers.

Step-by-step explanation:

So, the number you need to find is between 0 and 9, because is a 1-digit number. For example, it cannot be 10 because 10 is a 2-digit number.

So, the number could be like 0,1,2,3...etc

In the table, the "X" in the left upper corner is the symbol for multiplication.

The "?" in the left lower corner represents the mystery number.

The table shows that the product of the mystery number and 1,2,3,4 and 5 is always an even number

For example, the product of the mystery number and 3 is even.

That means that our mystery must be even.

So, we know that the mystery number is between 0 and 9 and it must be even.

Therefore, the mystery number can be one of the following numbers:

0, 2, 4, 6, 8

Plllzzz im new and i neeed help
ella [17]

Answer:

4082

Step-by-step explanation:

Given

The composite object

Required

The volume

The object is a mix of a cone and a hemisphere

Such that:

<u>Cone</u>

r = 10cm ---- radius (r = 20/2)

h = 19cm

<u>Hemisphere</u>

r=10cm

The volume of the cone is:

V_1 = \frac{1}{3}\pi r^2h

V_1 = \frac{1}{3}\pi * 10^2 * 19

V_1 = \frac{1900}{3}\pi

The volume of the hemisphere is:

V_2 = \frac{2}{3}\pi r^3

V_2 = \frac{2}{3}\pi 10^3

V_2 = \frac{2000}{3}\pi

So, the volume of the object is:

V = V_1 + V_2

V = \frac{1900}{3}\pi + \frac{2000}{3}\pi

V = \frac{3900}{3}\pi

V = 1300\pi

V = 1300 * 3.14

V = 4082
