Answer:

11.   p = 59.2^\circ

12.   C.  x \tan q

Step-by-step explanation:

11.

First, find side DB.

(DB)^2 = 6^2 + 5^2

DB = \sqrt{61}

Now find m<p.

\cos p = \dfrac{adj}{hyp}

\cos p = \dfrac{4}{\sqrt{61}}

p = \cos^{-1} \dfrac{4}{\sqrt{61}}

12.

Let the height be y.

\tan q = \dfrac{y}{x}

y = x \tan q

An open box is to be constructed from a square piece of sheet metal by removing a square of side 6 feet from each corner and tur
den301095 [7]

Answer:

24 feet

Step-by-step explanation:

We are given that an open box is to be constructed from a square piece of sheet metal by removing a square side 6 feet from each corner and turning up the edges.

We have to find the dimensions of the sheet metal

Let x feet be the side of square  metal sheet

Length of box=x-12 feet (because 6 feet removed from each corner)

Width of box=x-12 feet

Height of box=6 feet

Volume of box=864 cubic feet

We know that volume of cuboid=l\times b\times h

Box is in cuboid shaped

Therefore, volume of box=6(x-12)(x-12)

6(x^2-24x+144)=864

x^2-24x+144=\frac{864}{6}

x^2-24x+144=144

x^2-24x+144-144=0

x(x-24)=0

Then ,x=0 , x-24=0

x=24

x=0 is not possible because side of square  metal sheet can not be zero

Therefore, x=24

All sides of square metal sheet are equal.

Hence, side of square metal sheet =24 feet

lozanna [386]

Answer:

40%

Step-by-step explanation:

Given that :

Cost of production of small latte = 2.10

Sale price of small latte = 2.94

The Markup = Sale price of small latte - cost of production of small latte

The Markup = 2.94 - 2.10 = 0.84

Percentage Markup = (0.84 / 2.10) * 100%

Percentage Markup = 0.4 * 100% = 40%
