1. Let the side length of each small square on the grid represent 1 unit. Draw two different triangles, e. Ach with base 5 1/2 units and area 19 1/4 units2. 2. Why does each of your triangles have area 1914 units2?

Answers

Answer:

Step-by-step explanation:

Given that:

Each small square on a grid represents 1 unit

Base of triangle = 5 1/2 units = 11/2

Area of triangle = 19 1/4 unit² = 77/4

The Area, A of a triangle is obtained thus :

77/4 = 1/2 * 11/2 * h

77/4 = 11/4 * h

h = 77/4 ÷ 11/4

h = 77/4 * 4 /11

h = 7 units

A sphere and a cylinder have the same radius and height. The volume of the cylinder is 11 feet cubed.

A sphere with height h and radius r. A cylinder with height h and radius r.

Which equation gives the volume of the sphere?
V = four-thirds (11) pi
V = two-thirds (11) pi
V = four-thirds (11)
V = two-thirds (11)

Answers

9514 1404 393

Answer:

  V = (2/3)(11)

Step-by-step explanation:

The given cylinder has a height of 2r, so its volume is ...

  V = πr²(2r) = 2πr³

The volume of a sphere is given by ...

  V = 4/3πr³

Then the ratio of the volume of the sphere to the volume of the cylinder is ...

  (4/3πr³)/(2πr³) = (4/3)/2 = 2/3

So, the volume of the sphere is 2/3 times the volume of the cylinder:

  V = (2/3)(11)

Answers

Answer:

[tex]a = 2[/tex] and [tex]b = 4[/tex]

Step-by-step explanation:

Given

The expression is:

[tex]\frac{x^2 + ax - 4}{x + 2} + \frac{x + b}{x + 2} = x + 1[/tex] --- missing from the question

Required

Find a and b

Take LCM

[tex]\frac{x^2 + ax - 4+x + b}{x + 2} = x + 1[/tex]

Cross Multiply

[tex]x^2 + ax - 4+x + b = (x+2)*(x + 1)[/tex]

Open brackets

[tex]x^2 + ax - 4+x + b = x^2+2x + x + 2[/tex]

[tex]x^2 + ax - 4+x + b = x^2+3x + 2[/tex]

Collect Like Terms

[tex]x^2 + ax +x + b- 4 = x^2+3x + 2[/tex]

[tex]x^2 + (a +1)x + b- 4 = x^2+3x + 2[/tex]

By comparing the coefficients:

[tex]a + 1 = 3[/tex]

[tex]a = 3 - 1[/tex]

[tex]a = 2[/tex]

[tex]b - 4 = 2[/tex]

[tex]b = 4[/tex]

Hence,

[tex]a = 2[/tex] and [tex]b = 4[/tex]

Answer:

a = 2

b = 6

Answer: w^2 + 15w + 54

Step-by-step explanation:

FOIL = first, outside, inside, last.

First —> multiply first numbers of each parentheses.

Outside —> multiple the OUTSIDE numbers in each parentheses (first number in the first parentheses, second number in the second parentheses.

Inside —> multiply the INSIDE numbers in each parentheses (the second number in the first parentheses, first number in the second parentheses).

Last —> multiply second number of each parentheses.

F = w^2

O = 6w

I = 9w

L = 54

Caroline uses 9.1 pints of blue paint and white paint to paint her bedroom walls. 1 4 of this amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls?

Answers

Answer:

6.83 pints

Step-by-step explanation:

The first step is to calculate the volume of the blue paint

= 9.1 × 1/4

= 2.275

Therefore the volume of the white paint can be calculated as follows

= 9.1 - 2.275

= 6.83

Hence the volume of white paint that Caroline used to paint her bedroom walls is 6.83 pints
