Question
A triangle with area 40 square inches has a height that is four less than six times the width. Find the width and height of the
triangle

Answers

Answer:

width is 4

height is 20

Step-by-step explanation:

Area=½ width × height

let the width be x

height will be 6x - 4

40 = ½ × x × (6x - 4)

40 = 2/2 × 3x² - 2x

40 = 3x² - 2x

3x² - 2x - 40 = 0

3x² -12x + 10x - 40 = 0

3x(x-4) + 10(x-4) = 0

(3x + 10)(x - 4) = 0

x = -10/3 or 4

dimension cannot be negative

Answer:

3/2^3=3/8 and (-1/4)^2 = 1/16

Step-by-step explanation:

1. You know what 2^3 is, right? That's 2*2*2. 2*2 is 4, and then 4*2 is 8. So that is 3/8.

2. (-1/4)^2 is (-1/4)*(-1/4), right? So that is (-1*-1)/(4*4). Two negatives make a positive, so -1*-1=1. 4*4 is 16, so we have 1/16.

The dimensions of a trapezoid are halved.
a) How will the area be affected?
b) If the area of the original trapezoid is 28 cm?, then what will the area of the smaller
trapezoid be?
Draw or add images here

Answers

Answer:

  a) area will be 1/4 of the original

  b) 7 cm²

Step-by-step explanation:

a)

Consider the equation for the area of a trapezoid:

  A = 1/2(b1 +b2)h

Now, halve each of the dimensions:

  A' = 1/2((1/2)b1 +(1/2)b2)((1/2)h)

  A' = (1/4)(1/2(b1 +b2)h) = 1/4A

The area is multiplied by the square of the scale factor: (1/2)² = 1/4.

__

b)

The area of the smaller trapezoid will be ...

  A' = 1/4A = (1/4)(28 cm²) = 7 cm²

A box is 36 inches long,18 inches wide, and 6 inches deep. How many cubic feet are in the box?

Answers

Answer:

3,888 ft³

Step-by-step explanation:

Multiply the dimensions together.

[tex](36)(18)(6)=3888[/tex]

Therefore, the box is 3,888 ft³.

The volume of the box in feet given its dimensions is 2 1/4 feet³.

What is the volume of the box?

The volume of the box can be determined by multiplying the length, width and height of the box with each other.

Before the volume can be determined, the dimensions have to be converted from inches to feet.

1 inch - 1/12 feet

Length = 36 / 12 = 3 feet Width = 18 / 12  = 3/2 feet Height = 6/12 = 1/2 feet

Volume = 3 x 3/2 x 1/2 = 9/4 = 2 1/4 feet³

(g, 6) and (-5, -9)

Slope = 3/2

Answers

Answer:

g=5

Step-by-step explanation:

(-9)-(6) / (-5)-(g) = 3/2

3 x -(g+5) = 2 x -15

g+5=10

g=5

Answer:

g=15

Step-by-step explanation:

we first can substitute in (-5,-9) into the x and y variables in y=mx+b as well as the slope:

so we get:

-9=3/2(-5)+b

now lets solve for b:

3/2 x -5 = -15/2

-9=-15/2+b

now add the -15/2 on both sides of the eqaution:

b=-33/2

now lets substitute it back in:

y=3/2x-33/2

NOW lol substitute the 6 in to find g:

6=3/2g-33/2

solve from here to get

45/2=3/2g

multiply by 2 on each side

45=3g

divide both sides by 3:

g=15!!!!!!!!!!!!!!
