Answer: $221.76

Step-by-step explanation:

Each wall has a length of 12 and a height of 8 and there are 4 walls

(12 x 8) x 4 = 384 sq ft

multiply sq ft by cost ($0.33)

384 x 0.33 = $126.72 for the walls and door

The ceiling has a length of 12 and a width of 12

12 x 12 = 144 sq ft

multiply sq ft by cost ($0.66)

144 x 0.66 = 95.04

add the costs

126.72 + 95.04 = $221.76 total

An archaeologist is categorizing the artifacts he has discovered. Two-thirds of the artifacts are shards of pottery. One-eighth
Reika [66]

Answer:

Personal items=15

Step-by-step explanation:

We are given:

Total number of artifacts = 72.

We are told that 2/3 of total artifacts are shards of pottery.

\text{Shards of pottery}=72*\frac{2}{3} =24*2=48

We are also told that 1/8 of total artifacts are tools.

\text{Tools}=72*\frac{1}{8}=9

Now we will find out number of personal items by subtracting combined number of shards of pottery and tools from total number of artifacts.

\text{ Personal items}=72-(48+9)

\text{ Personal items}=72-57=15

Therefore, there are 15 personal items.

What is the length of the hypotenuse of the triangle when x=13
ValentinkaMS [17]

Answer:

90.80

Step-by-step explanation:

6x+4

= (6)(13)+4

= 78+4

=82

3x

=(3)(13)

= 39

So we know the sides are 39 and 82

Pythagoras theorem in triangles

= a2+b2= c2

Now, we know the value of a and B but not c (the hypotenuse)

Therefore,

c2 = (39)^2 + (82)^2

= 1521+ 6724

= 8245

so, c = √8245

= 90.80 unitd

Sec theta - Csc theta / (csc theta)(sec theta)
Sophie [7]

Answer:

sin(x)-cos(x)

Step-by-step explanation:

\frac{\frac{1}{cos(x)} - \frac{1}{sin(x)}  }{\frac{1}{sin(x)} * \frac{1}{cos(x)}  }

Simplify the denominator:

\frac{\frac{1}{cos(x)} - \frac{1}{sin(x)}  }{\frac{1}{cos(x)sin(x)}  }

Simplify the numerator:

\frac{{\frac{2(sin(x)-cos(x))}{sin(2x)} }  }{\frac{1}{sin(x)} * \frac{1}{cos(x)}  }

Divide the fractions: <u>(a/b)/(c/d) = (a * d)/(b * c)</u>:

\frac{(-cos(x)+sin(x))*2cos(x)sin(x)}{sin(2x)}

Use the identity: <u>2cos(x)sin(x) = sin(2x):</u>

\frac{sin(2x)(-cos(x)+sin(x))}{sin(2x)}

Cancel out the common factor (sin(2x)):

-cos(x) + sin(x)

Simplify:

sin(x) - cos(x)
