When a spaceship full of scientists landed on Planet Q, they found that 3/8 of the 160 aliens had 3 eyes. The rest of the aliens had 5 eyes. How many eyes total do the 160 aliens have?

Answer:

228cm^2

Step-by-step explanation:

Formulas we'll use: area of a rectangle is length x width, and area of a triangle = 1/2x base x height

the base is a rectangle, 10 by 3 cm. 10 x 3 = 30cm^2

the sides are also rectangles, 13 by 3 cm. 13 x 3 = 39, but there are 2 of them, 39 x 2 = 78cm^2

The top and bottom are triangles, 1/2(10)(12) = 1/2(120) = 60, but there are 2 of them, 60 x 2 = 120cm^2

Add up the areas to get your total surface area. It's in square cm

30 + 78 + 120 = 228cm^2

Answer and Step-by-step explanation:

To find the length of z, we need the lengths of the other 2 sides first. Simply take the square root of both areas and that will be your sides.

[tex]\sqrt{13}[/tex] and [tex]\sqrt{29.25}[/tex]

Now find z, the hypotenuse.

[tex](\sqrt{13}) ^2 + (\sqrt{29.25} )^2 =z^2\\\\13 + 29.25 = z^2\\\\42.25 = z^2\\\\\sqrt{42.25} = z\\\\6.5 = z[/tex]

6.5 is the answer.

Answer: 11 1/2 ft

Step-by-step explanation:

We know that the equation for the area of a rectangle is:

length x width = area

All we have to do is fill it in with the numbers and solve:

length x 8 1/3 = 95 5/6

length = 95 5/6 ÷ 8 1/3

length = 23/2 = 11 1/2

Thus, the length of Tamara's room is 11 1/2 feet.

Answer:

1/13

Step-by-step explanation:

Answer:

1/13 is the answer  

Step-by-step explanation:

The value of n is 4. That means, the process is applied 4 times.

Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times.

Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.

Given:

To encode a message,

James first replaces each letter within the message with its corresponding number, where A = 1, B = 2, · · ·, Y = 25, and Z = 26. Next, James multiplies each number by 3 and then subtracts 5, and continues this process a total of n times.

To find the value of n:

We use process inversely.

Let m be the given number.

For example,

m = 16

The inverse process;

add 5 and then divide by 3 until we get the whole number.

So, first time

(16 + 5)/3 = 21/3 = 7,

Second time applying process,

(7+5)/3 = 4.

And the corresponding letter is D.

And the value of n is 2.

Now, m = 367

Applying process inversely,

First time,

(367 + 5) / 3 = 124

Second time,

(124+5)/3 = 43

Third time,

(43+5)/3 = 16

Fourth time,

(16+5)/3 = 7

m = 205

Applying process inversely,

First time,

(205+ 5) / 3 = 70

Second time,

(70+5)/3 = 25

Third time,

(25+5)/3 = 10

Fourth time,

(10+5)/3 = 5

m = 853

Applying process inversely,

First time,

(853+ 5) / 3 = 286

Second time,

(286+5)/3 = 97

Third time,

(97+5)/3 = 34

Fourth time,

(34+5)/3 = 13

m = 1339

Applying process inversely,

First time,

(1339+ 5) / 3 = 448

Second time,

(448+5)/3 = 151

Third time,

(151+5)/3 = 52

Fourth time,

(52+5)/3 = 19

We applied the process 4 times.

Therefore, the value of n is 4.

c-90

Step-by-step explanation:

blue shape-90 degree angle

pink is 45 since 2 make up a quadrant

aqua is 30 because half 2 quadrants equal 180.

180-(45x2)=90

Answer:

2 5/8

Step-by-step explanation:

3 1/8 - 1/2​

Get a common denominator

3 1/8 - 1/2 *4/4

3 1/8 - 4/8

Borrow 1 from the 3 in the form of 8/8

2 + 8/8+1/8 - 4/8

2 9/8 - 4/4

2 5/8

Answer:

21/8 or 2 5/8

Step-by-step explanation:

Step 1: Find a common denominator for 1/2 to have the same denominator as 3 1/8:

1/2 is equal to 4/8, which has the same denominator as 3 1/8.

Step 2: Convert the mixed fraction into an improper fraction so it will be easier to subtract.

3 1/8 = 25/8

Step 3: Now subtract:

25/8 - 4/8 = 21/8 or 2 5/8 (keep the denominator the same)

Answer:

1) x= -1/27

2) x=-4

3) x=13

Step-by-step explanation:

1) 7+7/9x= = -42

   14/9x= = -42

  14/9x X 9x= -42 X 9x

    14= -378x

    -378x= 14

   -378x/-378= 14/-378

      x= -1/27

2) 4x+1=−15

 4x+1-1=-15-1

    4x=-16

   4x/4= -16/4

      x=-4

3) −4(x−3)=−40

 -4(x-3)/-4= -40/4

     x-3=10

   x-3+3=10+3
