Answer:

112 cm

Step-by-step explanation:

First find the area of the triangle. Formula: 1/2bh

Base of 8 times height of 4 = 32. Then you divide 32 by 2(or multiple by 1/2, it's essentially the same) to get 16.

Now that you've found the area of the triangle, you multiply that by the length of the shape. (7cm)

16*7 = 112

So the volume of the shape = 112cm^3

The manufacturer of a wooden feeding trough for farm animals makes the sides and bottom of the trough 1 foot thick. The outer he

Tju [1.3M]

Answer:

outer width of trough = outer height of trough = x = 4ft

outer length of trough = 2x = 8ft

Step-by-step explanation:

Let,

x = outer width of trough = outer height of trough

Now, according to given condition:

2x = outer length of trough

Now we calculate the inner dimensions by subtracting the thickness (1 ft)

Therefore,

x - 2(1ft) = x - 2ft = inner width of trough (because 1ft from both sides will be subtracted)

x - 1ft = inner height of trough (because only bottom thickness will be subtracted)

2x - 2ft = inner length of trough (because 1ft from both sides will be subtracted)

Now, for the holding volume or inside volume of trough will be:

$Inner Volume = 36\ ft^3 = inner\ height*inner\ width*inner\ length \\36 = (x - 1)(x - 2)(2x - 2)\\36 = (x - 1)(2x^2 - 6x + 4)\\36 = (2x^3 - 6x^2 + 4x - 2x^2 + 6x - 4)\\36 = (2x^3 -8x^2 + 10x - 4) \\2x^3 -8x^2 + 10x - 40 = 0\\2x^2(x-4)+10(x-4) = 0\\(x-4)(2x^2+10) = 0\\$

So, we will have three roots from this solution. Two, of them will be complex from the second factor. So, we ignore them and take the third one as our answer:

x - 4 = 0

x = 4ft

Now the outer dimensions will be:

outer width of trough = outer height of trough = x = 4ft

outer length of trough = 2x = 8ft

Zack watered his garden with 1 3/8

victus00 [196]

Answer:

The correct answer is that Zack used 2 7/8 gallons to water his garden on the fifth week.

Step-by-step explanation:

Let's find out the pattern Zack is using to water his garden, this way:

First week = 1 3/8 gallons of water

Second week = 1 3/4 gallons of water = 1 3/8 + 3/8 = 1 6/8 = 1 3/4

Third week = 2 1/8 gallons of water = 1 3/4 + 3/8 = 1 6/8 + 3/8 = 2 1/8

The constant of adding every week is 3/8 gallons, therefore,

Fourth week = 2 1/8 + 3/8 = 2 4/8 = 2 1/2 gallons of water

Fifth week = 2 1/2 + 3/8 = 2 4/8 + 3/8 = 2 7/8 gallons of water

The correct answer is that Zack used 2 7/8 gallons to water his garden on the fifth week.

Can someone help me solve x

evablogger [386]

Answer:6

Step-by-step explanation:solve the equation, you know that it equals 90 because the angle is 90

so 16x-6=90

+6 both sides

16x=96

divided by 16 both sides to isolate x

x=6

Consider a triangle with two sides that

AURORKA [14]

9514 1404 393

Answer:

C) 14 cm

Step-by-step explanation:

A triangle solver can quickly show you the third side is 14 cm.

The law of cosines can be used for this purpose. If the given sides are 'a' and 'b', and the third side is 'c', then that law tells you ...

c² = a² +b² -2ab·cos(C)

c² = 7² +11² -2·7·11·cos(100°) ≈ 196.74

c ≈ √196.74 ≈ 14.03

The length of the third side is about 14 cm.
