Brady started to fill the box shown with some unit cubes.

Enter the total number of unit cubes needed to completely fill the box.Include the unit cubes already shown in your total.



Answers

Answer:

210

Step-by-step explanation:

Step 1: 6 rows and 6 columns each side so 6*6=36

Step 2: we have 6 sides so 36*6=216 cubes

Step 3: substract 6 cubes from the total since each row and column shares the same cube 216-6=210 cubes

The total number of unit cubes is A = 210 cubes and volume is V = 216 units³

What is the Volume of a Rectangle?

The volume of the rectangle is given by the product of the length of the rectangle and the width of the rectangle and the height of the rectangle

Volume of Rectangle = Length x Width x Height

Volume of Rectangle = Area of Rectangle x Height

Given data ,

Let the height of the rectangle be = 6 units

Let the length of the rectangle be = 5 units

And , let the width be = 7 units

So , Volume of Rectangle = Length x Width x Height

V = 6 x 5 x 7

V = 210 units³

Hence , the number of unit cubes is A = 210

Distance will be 5.66

Answer:

5.66

Step-by-step explanation:

Given,

Point A = 2,3

Point B = -2, -1

So,

X1 = 2, X2 = -2 , Y1 = 3 , Y2 = -1

Therefore,

Distance between Point A and B is

[tex] = \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} } [/tex]

[tex] = \sqrt{ {( - 2 - 2)}^{2} + {( - 1 - 3)}^{2} } [/tex]

Step-by-step explanation:

A heavy piece of equipment has wheels on one side and legs on the other as shown in the diagram below.

Two people are trying to move the equipment. Each person grabs a handle and begins to lift. The first person imparts an upward force of 300 N and the second person imparts an upward force of 290 N. This is enough to lift the side of the equipment, but they also need to get it moving.
While maintaining the upward forces, the first person imparts a horizontal force of 185 N and the second person a horizontal force of 205 N. They maintain these forces while the equipment begins to move.

What is the total force in the horizontal direction?
____ N   

What is the total force in the upward direction?
____ N   

Determine the magnitude and direction of this resultant vector (the resultant vector from combining the forces of the two people).

Magnitude: ____ N   

Direction: _____ °   


Answers

9514 1404 393

Answer:

horizontal: 390 Nvertical: 590 N707.2∠56.5° N

Step-by-step explanation:

The problem statement tells you the two horizontal forces are 185 N and 205 N. The total horizontal force is (185 +205) N = 390 N.

The vertical forces are said to be 300 N and 290 N. The total vertical force is (300 +290) N = 590 N.

The magnitude of the resultant is the root of the sum of the squares:

  √(390² +590²) = √(152100 +348100) = √500200 ≈ 707.248

The angle of the resultant (relative to the horizontal) is ...

  α = arctan(vertical/horizontal) = arctan(590/390) ≈56.53°

The resultant force is about 707.2 N at an angle of 56.5° above the horizontal.

A zoologist studied the wild cat population of two islands during a four year span - Meow Island and Purr Island. She collected the following data about the population.



1. How would you describe the growth of each island ?

2. Which do you think will be modeled by a linear function ?

Answers

Answer:

Meow Island has a linear function.

Step-by-step explanation:

Meow Island increases by multiply the input by 3 for each coordinate. On the other hand, Purr Island increases by adding 4. Linear functions increase with multiplication, not by addition, and so Meow Island increases linearly.

Move all terms containing x to the left side of the equation.

Subtract 3x from both sides of the equation.

3x+9−3x=11

Combine the opposite terms in

3x+9−3x.

Subtract 3x from 3x.
