The volume of the smaller cube:
Volume of a cube = Length³
Volume of a cube = 1³ = 1 ft.³
The volume of the larger cuboid:
Volume of a cuboid = Length × Width × Height
Volume of a cuboid = 13 × 7 × 8
= 728 ft.³

The volume of the composed figure:
728 ft³ + 1 ft.³ = 729 ft³

Suppose triangle ABC has vertices at A(1, 0), B(10, 0), and C(2, 6). After a 60° counterclockwise rotation about the origin, ver

Artemon [7]

Check the picture attached.

Let OB be the radius of circle with center O.

Let B' be the image of B after the described rotation

OB and OB' are sides of the equilateral triangle OBB'.

The x coordinate of B' is the midpoint of OB, that is 5.

In the right triangle B', point (5, 0) and B:

Distance point (5, 0) to B is 5
|B'B|=|OB|=10

so by the pythagorean theorem:

$a= \sqrt{ 10^{2} - 5^{2} } = \sqrt{ 2^{2} *5^{2} - 5^{2} }= \sqrt{5^{2}(4-1)}=5 \sqrt{3}$ units

Answer: $5 \sqrt{3}$

Answer:

343 gallons, So Sarah dumped water in the pool each minute consists of 7 gallons so if she did it for 49 minutes, thats 7 gallons each for each minute. So you do 7 times 49 which gives you how many gallons in those total minutes.

-10 Fish because they re removing fish they removed 60 for 6 days so you have to figure out how many fish they have removed each day so 60 fish divided by how many days equals how many fish they have taken out each day.

Im sorry i forgot the negative again lol

Answer:

20,18,16,14,12,10,8,6,4,2

10,9,8,7,6,5,4,3,2,1

Step-by-step explanation:

Pattern A:

Rule : start with 20 and subtract 2

Pattern B:

Rule : Start with 10 and subtract 1

Pattern 1:

20 - 2 = 18

18 - 2 = 16

16 - 2 = 14

14 - 2 = 12

12 - 2 = 10

10 - 2 = 8

8 - 2 = 6

6 - 2 = 4

4 - 2 = 2

20,18,16,14,12,10,8,6,4,2

Pattern 2:

10 - 1 = 9

9 - 1 = 8

8 - 1 = 7

7 - 1 = 6

6 - 1 = 5

5 - 1 = 4

4 - 1 = 3

3 - 1 = 2

2 - 1 = 1
